|
|
|
46 ;;; This package attempts to make accessing files and directories on
|
|
|
47 ;;; remote computers from within GNU Emacs as simple and transparent
|
|
|
48 ;;; as possible. Currently all remote files are accessed using FTP.
|
|
|

76 ;;; If you have any problems with efs, please read this section

|
|
|
79 ;;; Installation:
|
|
|
80 ;;;
|
|
|
81 ;;; For byte compiling the efs package, a Makefile is provided.
|
|
|
82 ;;; You should follow the instructions at the top of the Makefile.
|
|
|
83 ;;; If you have any problems, please let us know so that we can fix
|
|
|
84 ;;; them for other users. Don't even consider using efs without
|
|
|
85 ;;; byte compiling it. It will be far too slow.
|
|
|
86 ;;;
|
|
|
87 ;;; If you decide to byte compile efs by hand, it is important that
|
|
|
88 ;;; the file efs-defun.el be byte compiled first, followed by efs.el.
|
|
|
89 ;;; The other files may be byte compiled in any order.
|
|
|
90 ;;;
|
|
|
91 ;;; To use efs, simply put the byte compiled files in your load path
|
|
|
92 ;;; and add
|
|
|
93 ;;;
|
|
|
94 ;;; (require 'efs)
|
|
|
95 ;;;
|
|
24
|
96 ;;; in your .emacs file. Note this takes awhile, and some users have
|
|
|
97 ;;; found this to be unbearably slow. Therefore ...
|
|
22
|
98 ;;;
|
|
|
99 ;;; If you would like efs to be autoloaded when you attempt to access
|
|
|
100 ;;; a remote file, put
|
|
|
101 ;;;
|
|
|
102 ;;; (require 'efs-auto)
|
|
|
103 ;;;
|
|
|
104 ;;; in your .emacs file. Note that there are some limitations associated
|
|
|
105 ;;; with autoloading efs. A discussion of them is given at the top of
|
|
|
106 ;;; efs-auto.el.
|
|
|
107
|
|
|
108 ;;; Configuration variables:
|
|
|
109 ;;;
|
|
|
110 ;;; It is important that you read through the section on user customization
|
|
|
111 ;;; variables (search forward for the string ">>>"). If your local network
|
|
|
112 ;;; is not fully connected to the internet, but accesses the internet only
|
|
|
113 ;;; via a gateway, then it is vital to set the appropriate variables to
|
|
|
114 ;;; inform efs about the geometry of your local network. Also, see the
|
|
|
115 ;;; paragraph on gateways below.
|
|
|
116
|
|
|
117 ;;; Usage:
|
|
|
118 ;;;
|
|
|
119 ;;; Once installed, efs operates largely transparently. All files
|
|
|
120 ;;; normally accessible to you on the internet, become part of a large
|
|
|
121 ;;; virtual file system. These files are accessed using an extended
|
|
|
122 ;;; file name syntax. To access file <path> on remote host <host> by
|
|
|
123 ;;; logging in as user <user>, you simply specify the full path of the
|
|
|
124 ;;; file as /<user>@<host>:<path>. Nearly all GNU Emacs file handling
|
|
|
125 ;;; functions work for remote files. It is not possible to access
|
|
|
126 ;;; remote files using shell commands in an emacs *shell* buffer, as such
|
|
|
127 ;;; commands are passed directly to the shell, and not handled by emacs.
|
|
|
128 ;;; FTP is the underlying utility that efs uses to operate on remote files.
|
|
|
129 ;;;
|
|
|
130 ;;; For example, if find-file is given a filename of:
|
|
|
131 ;;;
|
|
|
132 ;;; /ange@anorman:/tmp/notes
|
|
|
133 ;;;
|
|
|
134 ;;; then efs will spawn an FTP process, connect to the host 'anorman' as
|
|
|
135 ;;; user 'ange', get the file '/tmp/notes' and pop up a buffer containing the
|
|
|
136 ;;; contents of that file as if it were on the local file system. If efs
|
|
|
137 ;;; needed a password to connect then it would prompt the user in the
|
|
|
138 ;;; minibuffer. For further discussion of the efs path syntax, see the
|
|
|
139 ;;; paragraph on extended file name syntax below.
|
|
|
140
|
|
|
141 ;;; Ports:
|
|
|
142 ;;;
|
|
|
143 ;;; efs supports the use of nonstandard ports on remote hosts.
|
|
|
144 ;;; To specify that port <port> should be used, give the host name as
|
|
|
145 ;;; host#<port>. Host names may be given in this form anywhere that efs
|
|
|
146 ;;; normally expects a host name. This includes in the .netrc file.
|
|
|
147 ;;; Logically, efs treats different ports to correspond to different
|
|
|
148 ;;; remote hosts.
|
|
|
149
|
|
|
150 ;;; Extended filename syntax:
|
|
|
151 ;;;
|
|
|
152 ;;; The default full efs path syntax is
|
|
|
153 ;;;
|
|
|
154 ;;; /<user>@<host>#<port>:<path>
|
|
|
155 ;;;
|
|
|
156 ;;; Both the `#<port>' and `<user>@' may be omitted.
|
|
|
157 ;;;
|
|
|
158 ;;; If the `#<port>' is omitted, then the default port is taken to be 21,
|
|
|
159 ;;; the usual FTP port. For most users, the port syntax will only
|
|
|
160 ;;; very rarely be necessary.
|
|
|
161 ;;;
|
|
|
162 ;;; If the `<user>@' is omitted, then efs will use a default user. If a
|
|
|
163 ;;; login token is specified in your .netrc file, then this will be used as
|
|
|
164 ;;; the default user for <host>. Otherwise, it is determined based on the
|
|
|
165 ;;; value of the variable efs-default-user.
|
|
|
166 ;;;
|
|
|
167 ;;; This efs path syntax can be customised to a certain extent by
|
|
|
168 ;;; changing a number of variables in the subsection Internal Variables.
|
|
|
169 ;;; To undertake such a customization requires some knowledge about the
|
|
|
170 ;;; internal workings of efs.
|
|
|
171
|
|
|
172 ;;; Passwords:
|
|
|
173 ;;;
|
|
|
174 ;;; A password is required for each host / user pair. This will be
|
|
|
175 ;;; prompted for when needed, unless already set by calling
|
|
|
176 ;;; efs-set-passwd, or specified in a *valid* ~/.netrc file.
|
|
|
177 ;;;
|
|
|
178 ;;; When efs prompts for a password, it provides defaults from its
|
|
|
179 ;;; cache of currently known passwords. The defaults are ordered such
|
|
|
180 ;;; that passwords for accounts which have the same user name as the
|
|
|
181 ;;; login which is currently underway have priority. You can cycle
|
|
|
182 ;;; through your list of defaults with C-n to cycle forwards and C-p
|
|
|
183 ;;; to cycle backwards. The list is circular.
|
|
|
184
|
|
|
185 ;;; Passwords for user "anonymous":
|
|
|
186 ;;;
|
|
|
187 ;;; Passwords for the user "anonymous" (or "ftp") are handled
|
|
|
188 ;;; specially. The variable efs-generate-anonymous-password controls
|
|
|
189 ;;; what happens. If the value of this variable is a string, then this
|
|
|
190 ;;; is used as the password; if non-nil, then a password is created
|
|
|
191 ;;; from the name of the user and the hostname of the machine on which
|
|
|
192 ;;; GNU Emacs is running; if nil (the default) then the user is
|
|
|
193 ;;; prompted for a password as normal.
|
|
|
194
|
|
|
195 ;;; "Dumb" UNIX hosts:
|
|
|
196 ;;;
|
|
|
197 ;;; The FTP servers on some UNIX machines have problems if the "ls"
|
|
|
198 ;;; command is used. efs will try to correct for this automatically,
|
|
|
199 ;;; and send the "dir" command instead. If it fails, you can call the
|
|
|
200 ;;; function efs-add-host, and give the host type as dumb-unix. Note
|
|
|
201 ;;; that this change will take effect for the current GNU Emacs
|
|
|
202 ;;; session only. To make this specification for future emacs
|
|
|
203 ;;; sessions, put
|
|
|
204 ;;;
|
|
|
205 ;;; (efs-add-host 'dumb-unix "hostname")
|
|
|
206 ;;;
|
|
|
207 ;;; in your .emacs file. Also, please report any failure to automatically
|
|
|
208 ;;; recognize dumb unix to the "bugs" address given below, so that we can
|
|
|
209 ;;; fix the auto recognition code.
|
|
|
210
|
|
|
211 ;;; File name completion:
|
|
|
212 ;;;
|
|
|
213 ;;; Full file-name completion is supported on every type of remote
|
|
|
214 ;;; host. To do filename completion, efs needs a listing from the
|
|
|
215 ;;; remote host. Therefore, for very slow connections, it might not
|
|
|
216 ;;; save any time. However, the listing is cached, so subsequent uses
|
|
|
217 ;;; of file-name completion will be just as fast as for local file
|
|
|
218 ;;; names.
|
|
|
219
|
|
|
220 ;;; FTP processes:
|
|
|
221 ;;;
|
|
|
222 ;;; When efs starts up an FTP process, it leaves it running for speed
|
|
|
223 ;;; purposes. Some FTP servers will close the connection after a period of
|
|
|
224 ;;; time, but efs should be able to quietly reconnect the next time that
|
|
|
225 ;;; the process is needed.
|
|
|
226 ;;;
|
|
|
227 ;;; The FTP process will be killed should the associated "*ftp user@host*"
|
|
|
228 ;;; buffer be deleted. This should not cause efs any grief.
|
|
|
229
|
|
|
230 ;;; Showing background FTP activity on the mode-line:
|
|
|
231 ;;;
|
|
|
232 ;;; After efs is loaded, the command efs-display-ftp-activity will cause
|
|
|
233 ;;; background FTP activity to be displayed on the mode line. The variable
|
|
|
234 ;;; efs-mode-line-format is used to determine how this data is displayed.
|
|
|
235 ;;; efs does not continuously track the number of active sessions, as this
|
|
|
236 ;;; would cause the display to change too rapidly. Rather, it uses a heuristic
|
|
|
237 ;;; algorithm to determine when there is a significant change in FTP activity.
|
|
|
238
|
|
|
239 ;;; File types:
|
|
|
240 ;;;
|
|
|
241 ;;; By default efs will assume that all files are ASCII. If a file
|
|
|
242 ;;; being transferred matches the value of efs-binary-file-name-regexp
|
|
|
243 ;;; then the file will be assumed to be a binary file, and efs will
|
|
|
244 ;;; transfer it using "type image". ASCII files will be transferred
|
|
|
245 ;;; using a transfer type which efs computes to be correct according
|
|
|
246 ;;; to its knowledge of the file system of the remote host. The
|
|
|
247 ;;; command `efs-prompt-for-transfer-type' toggles the variable
|
|
|
248 ;;; `efs-prompt-for-transfer-type'. When this variable is non-nil, efs
|
|
|
249 ;;; will prompt the user for the transfer type to use for every FTP
|
|
|
250 ;;; transfer. Having this set all the time is annoying, but it is
|
|
|
251 ;;; useful to give special treatment to a small set of files.
|
|
|
252 ;;; There is also variable efs-text-file-name-regexp. This is tested before
|
|
|
253 ;;; efs-binary-file-name-regexp, so if you set efs-text-file-name-regexp
|
|
|
254 ;;; to a non-trivial regular expression, and efs-binary-file-name-regexp
|
|
|
255 ;;; to ".*", the result will to make image the default tranfer type.
|
|
|
256 ;;;
|
|
|
257 ;;; Also, if you set efs-treat-crlf-as-nl, then efs will use type image
|
|
|
258 ;;; to transfer files between hosts whose file system differ only in that
|
|
|
259 ;;; one specifies end of line as CR-LF, and the other as NL. This is useful
|
|
|
260 ;;; if you are transferring files between UNIX and DOS machines, and have a
|
|
|
261 ;;; package such as dos-mode.el, that handles the extra ^M's.
|
|
|
262
|
|
|
263 ;;; Account passwords:
|
|
|
264 ;;;
|
|
|
265 ;;; Some FTP servers require an additional password which is sent by
|
|
|
266 ;;; the ACCOUNT command. efs will detect this and prompt the user for
|
|
|
267 ;;; an account password if the server expects one. Also, an account
|
|
|
268 ;;; password can be set by calling efs-set-account, or by specifying
|
|
|
269 ;;; an account token in the .netrc file.
|
|
|
270 ;;;
|
|
|
271 ;;; Some operating systems, such as CMS, require that ACCOUNT be used to
|
|
|
272 ;;; give a write access password for minidisks. efs-set-account can be used
|
|
|
273 ;;; to set a write password for a specific minidisk. Also, tokens of the form
|
|
|
274 ;;; minidisk <minidisk name> <password>
|
|
|
275 ;;; may be added to host lines in your .netrc file. Minidisk tokens must be
|
|
|
276 ;;; at the end of the host line, however there may be an arbitrary number of
|
|
|
277 ;;; them for any given host.
|
|
|
278
|
|
|
279 ;;; Preloading:
|
|
|
280 ;;;
|
|
|
281 ;;; efs can be preloaded, but must be put in the site-init.el file and
|
|
|
282 ;;; not the site-load.el file in order for the documentation strings for the
|
|
|
283 ;;; functions being overloaded to be available.
|
|
|
284
|
|
|
285 ;;; Status reports:
|
|
|
286 ;;;
|
|
|
287 ;;; Most efs commands that talk to the FTP process output a status
|
|
|
288 ;;; message on what they are doing. In addition, efs can take advantage
|
|
|
289 ;;; of the FTP client's HASH command to display the status of transferring
|
|
|
290 ;;; files and listing directories. See the documentation for the variables
|
|
|
291 ;;; efs-hash-mark-size, efs-send-hash and efs-verbose for more details.
|
|
|
292
|
|
|
293 ;;; Caching of directory information:
|
|
|
294 ;;;
|
|
|
295 ;;; efs keeps an internal cache of file listings from remote hosts.
|
|
|
296 ;;; If this cache gets out of synch, it can be renewed by reverting a
|
|
|
297 ;;; dired buffer for the appropriate directory (dired-revert is usually
|
|
|
298 ;;; bound to "g").
|
|
|
299 ;;;
|
|
|
300 ;;; Alternatively, you can add the following two lines to your .emacs file
|
|
|
301 ;;; if you want C-r to refresh efs's cache whilst doing filename
|
|
|
302 ;;; completion.
|
|
|
303 ;;; (define-key minibuffer-local-completion-map "\C-r" 'efs-re-read-dir)

305
|
|
|
306 ;;; Gateways:
|
|
|
307 ;;;
|
|
40
|
308 ;;; Sometimes it is necessary for the FTP process to be run on a different
|
|
22
|
309 ;;; machine than the machine running GNU Emacs. This can happen when the
|
|
|
310 ;;; local machine has restrictions on what hosts it can access.
|
|
|
311 ;;;
|
|
|
312 ;;; efs has support for running the ftp process on a different (gateway)
|
|
|
313 ;;; machine. The way it works is as follows:
|
|
|
314 ;;;
|
|
|
315 ;;; 1) Set the variable 'efs-gateway-host' to the name of a machine
|
|
|
316 ;;; that doesn't have the access restrictions. If you need to use
|
|
|
317 ;;; a nonstandard port to access this host for gateway use, then
|
|
|
318 ;;; specify efs-gateway-host as "<hostname>#<port>".
|
|
|
319 ;;;
|
|
|
320 ;;; 2) Set the variable 'efs-ftp-local-host-regexp' to a regular expression
|
|
|
321 ;;; that matches hosts that can be contacted from running a local ftp
|
|
|
322 ;;; process, but fails to match hosts that can't be accessed locally. For
|
|
|
323 ;;; example:
|
|
|
324 ;;;
|
|
|
325 ;;; "\\.hp\\.com$\\|^[^.]*$"
|
|
|
326 ;;;
|
|
|
327 ;;; will match all hosts that are in the .hp.com domain, or don't have an
|
|
|
328 ;;; explicit domain in their name, but will fail to match hosts with
|
|
|
329 ;;; explicit domains or that are specified by their ip address.
|
|
|
330 ;;;
|
|
|
331 ;;; 3) Set the variable `efs-local-host-regexp' to machines that you have
|
|
|
332 ;;; direct TCP/IP access. In other words, you must be able to ping these
|
|
|
333 ;;; hosts. Usually, efs-ftp-local-host-regexp and efs-local-host-regexp
|
|
|
334 ;;; will be the same. However, they will differ for so-called transparent
|
|
|
335 ;;; gateways. See #7 below for more details.
|
|
|
336 ;;;
|
|
|
337 ;;; 4) Set the variable 'efs-gateway-tmp-name-template' to the name of
|
|
|
338 ;;; a directory plus an identifying filename prefix for making temporary
|
|
|
339 ;;; files on the gateway. For example: "/tmp/hplose/ange/efs"
|
|
|
340 ;;;
|
|
|
341 ;;; 5) If the gateway and the local host share cross-mounted directories,
|
|
|
342 ;;; set the value of `efs-gateway-mounted-dirs-alist' accordingly. It
|
|
|
343 ;;; is particularly useful, but not mandatory, that the directory
|
|
|
344 ;;; of `efs-gateway-tmp-name-template' be cross-mounted.
|
|
|
345 ;;;
|
|
|
346 ;;; 6) Set the variable `efs-gateway-type' to the type gateway that you have.
|
|
|
347 ;;; This variable is a list, the first element of which is a symbol
|
|
|
348 ;;; denoting the type of gateway. Following elements give further
|
|
|
349 ;;; data on the gateway.
|
|
|
350 ;;;
|
|
|
351 ;;; Supported gateway types:
|
|
|
352 ;;;
|
|
|
353 ;;; a) local:
|
|
|
354 ;;; This means that your local host is itself the gateway. However,
|
|
|
355 ;;; it is necessary to use a different FTP client to gain access to
|
|
|
356 ;;; the outside world. If the name of the FTP client were xftp, you might
|
|
|
357 ;;; set efs-gateway-type to
|
|
|
358 ;;;
|
|
|
359 ;;; (list 'local "xftp" efs-ftp-program-args)
|
|
|
360 ;;;
|
|
|
361 ;;; If xftp required special arguments, then give them in place of
|
|
|
362 ;;; efs-ftp-program-args. See the documentation for efs-ftp-program-args
|
|
|
363 ;;; for the syntax.
|
|
|
364 ;;;
|
|
|
365 ;;; b) proxy:
|
|
|
366 ;;; This indicates that your gateway works by first FTP'ing to it, and
|
|
|
367 ;;; then issuing a USER command of the form
|
|
|
368 ;;;
|
|
|
369 ;;; USER <username>@<host>
|
|
|
370 ;;;
|
|
|
371 ;;; In this case, you might set efs-gateway-type to
|
|
|
372 ;;;
|
|
|
373 ;;; (list 'proxy "ftp" efs-ftp-program-args)
|
|
|
374 ;;;
|
|
|
375 ;;; If you need to use a nonstandard client, such as iftp, give this
|
|
|
376 ;;; instead of "ftp". If this client needs to take special arguments,
|
|
|
377 ;;; give them instead of efs-ftp-program-args.
|
|
|
378 ;;;
|
|
|
379 ;;; c) remsh:
|
|
|
380 ;;; For this type of gateway, you need to start a remote shell on
|
|
|
381 ;;; your gateway, using either remsh or rsh. You should set
|
|
|
382 ;;; efs-gateway-type to something like
|
|
|
383 ;;;
|
|
|
384 ;;; (list 'remsh "remsh" nil "ftp" efs-ftp-program-args)
|
|
|
385 ;;;
|
|
|
386 ;;; If you use rsh instead of remsh, change the second element from
|
|
|
387 ;;; "remsh" to "rsh". Note that the symbol indicating the gateway
|
|
|
388 ;;; type should still be 'remsh. If you want to pass arguments
|
|
|
389 ;;; to the remsh program, give them as the third element. For example,
|
|
|
390 ;;; if you need to specify a user, make this (list "-l" "sandy").
|
|
|
391 ;;; If you need to use a nonstandard FTP client, specify that as the fourth
|
|
|
392 ;;; element. If your FTP client needs to be given special arguments,
|
|
|
393 ;;; give them instead of efs-ftp-program-args.
|
|
|
394 ;;;
|
|
|
395 ;;; d) interactive:
|
|
|
396 ;;; This indicates that you need to establish a login on the gateway,
|
|
|
397 ;;; using either telnet or rlogin.
|
|
|
398 ;;; You should set efs-gateway-type to something like
|
|
|
399 ;;;
|
|
|
400 ;;; (list 'interactive "rlogin" nil "exec ftp" efs-ftp-program-args)
|
|
|
401 ;;;
|
|
|
402 ;;; If you need to use telnet, then give "telnet" in place of the second
|
|
|
403 ;;; element "rlogin". If your login program needs to be given arguments,
|
|
|
404 ;;; then they should be given in the third slot. The fourth element
|
|
|
405 ;;; is for the name of the FTP client program. Giving this as "exec ftp",
|
|
|
406 ;;; instead of "ftp", ensures that you are logged out if the FTP client
|
|
|
407 ;;; dies. If the FTP client takes special arguments, give these instead
|
|
|
408 ;;; of efs-ftp-program-args. Furthermore, you should see the documentation
|
|
|
409 ;;; at the top of efs-gwp.el. You may need to set the variables
|
|
|
410 ;;; efs-gwp-setup-term-command, and efs-gwp-prompt-pattern.
|
|
|
411 ;;;
|
|
|
412 ;;; e) raptor:
|
|
|
413 ;;; This is a type of gateway where efs is expected to specify a gateway
|
|
|
414 ;;; user, and send a password for this user using the ACCOUNT command.
|
|
|
415 ;;; For example, to log in to foobar.edu as sandy, while using the account
|
|
|
416 ;;; ange on the gateway, the following commands would be sent:
|
|
|
417 ;;;
|
|
|
418 ;;; open raptorgate.com
|
|
|
419 ;;; quote USER sandy@foobar.edu ange
|
|
|
420 ;;; quote pass <sandy's password on foobar>
|
|
|
421 ;;; quote account <ange's password on raptorgate>
|
|
|
422 ;;;
|
|
|
423 ;;; For such a gateway, you would set efs-gateway-type to
|
|
|
424 ;;;
|
|
|
425 ;;; (list 'raptor efs-ftp-program efs-ftp-program-args <GATEWAY USER>)
|
|
|
426 ;;;
|
|
|
427 ;;; where <GATEWAY USER> is the name of your account on the gateway. In
|
|
|
428 ;;; the above example, this would be "ange". You can set your gateway
|
|
|
429 ;;; password by simply setting an account password for the gateway host.
|
|
|
430 ;;; This can be done with either efs-set-account, or within your .netrc
|
|
|
431 ;;; file. If no password is set, you will be prompted for one.
|
|
|
432 ;;;
|
|
|
433 ;;; f) interlock:
|
|
|
434 ;;; This is a type of gateway where you are expected to send a PASS
|
|
|
435 ;;; command after opening the connection to the gateway.
|
|
|
436 ;;; The precise login sequence is
|
|
|
437 ;;;
|
|
|
438 ;;; open interlockgate
|
|
|
439 ;;; quote PASS <sandy's password on interlockgate>
|
|
|
440 ;;; quote USER sandy@foobar.edu
|
|
|
441 ;;; quote PASS <sandy's password on foobar.edu>
|
|
|
442 ;;;
|
|
|
443 ;;; For such a gateway, you should set efs-gateway-type to
|
|
|
444 ;;;
|
|
|
445 ;;; (list 'interlock efs-ftp-program efs-ftp-program-args)
|
|
|
446 ;;;
|
|
|
447 ;;; If you need to use a nonstandard name for your FTP client,
|
|
|
448 ;;; then replace efs-ftp-program with this name. If your FTP client
|
|
|
449 ;;; needs to take nonstandard arguments, then replace efs-ftp-program-args
|
|
|
450 ;;; with these arguments. See efs-ftp-program-args <V> for the required
|
|
|
451 ;;; syntax.
|
|
|
452 ;;;
|
|
|
453 ;;; If your gateway returns both a 220 code and a 331 code to the
|
|
|
454 ;;; "open interlockgate" command, then you should add a regular
|
|
|
455 ;;; expression to efs-skip-msgs <V> that matches the 220 response.
|
|
|
456 ;;; Returning two response codes to a single FTP command is not permitted
|
|
|
457 ;;; in RFC 959. It is not possible for efs to ignore the 220 by default,
|
|
|
458 ;;; because than it would hang for interlock installations which do not
|
|
|
459 ;;; require a password.
|
|
|
460 ;;;
|
|
|
461 ;;; g) kerberos:
|
|
|
462 ;;; With this gateway, you need to authenticate yourself by getting a
|
|
|
463 ;;; kerberos "ticket" first. Usually, this is done with the kinit program.
|
|
|
464 ;;; Once authenticated, you connect to foobar.com as user sandy with the
|
|
|
465 ;;; sequence: (Note that the "-n" argument inhibits automatic login.
|
|
|
466 ;;; Although, in manual use you probably don't use it, efs always uses it.)
|
|
|
467 ;;;
|
|
|
468 ;;; iftp -n
|
|
|
469 ;;; open foobar.com
|
|
|
470 ;;; user sandy@foobar.com
|
|
|
471 ;;;
|
|
|
472 ;;; You should set efs-gateway-type to something like
|
|
|
473 ;;;
|
|
|
474 ;;; (list 'kerberos "iftp" efs-ftp-program-args "kinit" <KINIT-ARGS>)
|
|
|
475 ;;;
|
|
|
476 ;;; If you use an FTP client other than iftp, insert its name instead
|
|
|
477 ;;; of "iftp" above. If your FTP client needs special arguments, give
|
|
|
478 ;;; them as a list of strings in place of efs-ftp-program-args. If
|
|
|
479 ;;; the program that you use to collect a ticket in not called "kinit",
|
|
|
480 ;;; then give its name in place of "kinit" above. <KINIT-ARGS> should be
|
|
|
481 ;;; any arguments that you need to pass to your kinit program, given as a
|
|
|
482 ;;; list of strings. Most likely, you will give this as nil.
|
|
|
483 ;;;
|
|
|
484 ;;; See the file efs-kerberos.el for more configuration variables. If you
|
|
|
485 ;;; need to adjust any of these variables, please report this to us so that
|
|
|
486 ;;; we can fix them for other users.
|
|
|
487 ;;;
|
|
|
488 ;;; If efs detects that you are not authenticated to use the gateway, it
|
|
|
489 ;;; will run the kinit program automatically, prompting you for a password.
|
|
|
490 ;;; If you give a password in your .netrc file for login the value of
|
|
|
491 ;;; efs-gateway-host <V> and user kerberos, then efs will use this to
|
|
|
492 ;;; obtain gateway authentication.
|
|
|
493 ;;;
|
|
|
494 ;;; 7) Transparent gateways:
|
|
|
495 ;;;
|
|
|
496 ;;; If your gateway is completely transparent (for example it uses
|
|
|
497 ;;; socks), then you should set efs-gateway-type to nil. Also,
|
|
|
498 ;;; set efs-ftp-local-host-regexp to ".*". However, efs-local-host-regexp,
|
|
|
499 ;;; must still be set to a regular expression matching hosts in your local
|
|
|
500 ;;; domain. efs uses this to determine which machines that it can
|
|
|
501 ;;; open-network-stream to. Furthermore, you should still set
|
|
|
502 ;;; efs-gateway-host to the name of your gateway machine. That way efs
|
|
|
503 ;;; will know that this is a special machine having direct TCP/IP access
|
|
|
504 ;;; to both hosts in the outside world, and hosts in your local domain.
|
|
|
505 ;;;
|
|
|
506 ;;; 8) Common Problems with Gateways:
|
|
|
507 ;;;
|
|
|
508 ;;; a) Spurious 220 responses:
|
|
|
509 ;;; Some proxy-style gateways (eg gateway type 'proxy or 'raptor),
|
|
|
510 ;;; return two 3-digit FTP reply codes to the USER command.
|
|
|
511 ;;; For example:
|
|
|
512 ;;;
|
|
|
513 ;;; open gateway.weird
|
|
|
514 ;;; 220 Connected to gateway.weird
|
|
|
515 ;;; quote USER sandy@foobar
|
|
|
516 ;;; 220 Connected to foobar
|
|
|
517 ;;; 331 Password required for sandy
|
|
|
518 ;;;
|
|
|
519 ;;; This is wrong, according to the FT Protocol. Each command must return
|
|
|
520 ;;; exactly one 3-digit reply code. It may be preceded by continuation
|
|
|
521 ;;; lines. What should really be returned is:
|
|
|
522 ;;;
|
|
|
523 ;;; quote USER sandy@foobar
|
|
|
524 ;;; 331-Connected to foobar.
|
|
|
525 ;;; 331 Password required for sandy.
|
|
|
526 ;;;
|
|
|
527 ;;; or even
|
|
|
528 ;;;
|
|
|
529 ;;; quote USER sandy@foobar
|
|
|
530 ;;; 331-220 Connected to foobar.
|
|
|
531 ;;; 331 Password required for sandy.
|
|
|
532 ;;;
|
|
|
533 ;;; Even though the "331-220" looks strange, it is correct protocol, and
|
|
|
534 ;;; efs will parse it properly.
|
|
|
535 ;;;
|
|
|
536 ;;; If your gateway is returning a spurious 220 to USER, a work-around
|
|
|
537 ;;; is to add a regular expression to `efs-skip-msgs' that matches
|
|
|
538 ;;; this line. It must not match the 220 line returned to the open
|
|
|
539 ;;; command. This work-around may not work, as some system FTP clients
|
|
|
540 ;;; also get confused by the spurious 220. In this case, the only
|
|
|
541 ;;; solution is to patch the gateway server. In either case, please
|
|
|
542 ;;; send a bug report to the author of your gateway software.
|
|
|
543 ;;;
|
|
|
544 ;;; b) Case-sensitive parsing of FTP commands:
|
|
|
545 ;;; Some gateway servers seem to treat FTP commands case-sensitively.
|
|
|
546 ;;; This is incorrect, as RFC 959 clearly states that FTP commands
|
|
|
547 ;;; are always to be case-insensitive. If this is a problem with your
|
|
|
548 ;;; gateway server, you should send a bug report to its author.
|
|
|
549 ;;; If efs is using a case for FTP commands that does not suit your server,
|
|
|
550 ;;; a possible work-around is to edit the efs source so that the required
|
|
|
551 ;;; case is used. However, we will not be making any changes to the
|
|
|
552 ;;; standard efs distribution to support this type of server behaviour.
|
|
|
553 ;;; If you need help changing the efs source, you should enquire with the
|
|
|
554 ;;; efs-help mailing list.

|
|
|
557 ;;; ---------------------------------------------------------------
|
|
|
558 ;;; Tips for using efs:
|
|
|
559 ;;; ---------------------------------------------------------------
|
|
|
560
|
|
|
561 ;;; 1) Beware of compressing files on non-UNIX hosts. efs will do it by
|
|
|
562 ;;; copying the file to the local machine, compressing it there, and then
|
|
|
563 ;;; sending it back. Binary file transfers between machines of different
|
|
|
564 ;;; architectures can be a risky business. Test things out first on some
|
|
|
565 ;;; test files. See "Bugs" below. Also, note that efs sometimes
|
|
|
566 ;;; copies files by moving them through the local machine. Again,
|
|
|
567 ;;; be careful when doing this with binary files on non-Unix
|
|
|
568 ;;; machines.
|
|
|
569 ;;;
|
|
|
570 ;;; 2) Beware that dired over ftp will use your setting of dired-no-confirm
|
|
|
571 ;;; (list of dired commands for which confirmation is not asked).
|
|
|
572 ;;; You might want to reconsider your setting of this variable,
|
|
|
573 ;;; because you might want confirmation for more commands on remote
|
|
|
574 ;;; direds than on local direds. For example, I strongly recommend
|
|
|
575 ;;; that you not include compress in this list. If there is enough
|
|
|
576 ;;; demand it might be a good idea to have an alist
|
|
|
577 ;;; efs-dired-no-confirm of pairs ( TYPE . LIST ), where TYPE is an
|
|
|
578 ;;; operating system type and LIST is a list of commands for which
|
|
|
579 ;;; confirmation would be suppressed. Then remote dired listings
|
|
|
580 ;;; would take their (buffer-local) value of dired-no-confirm from
|
|
|
581 ;;; this alist. Who votes for this?
|
|
|
582 ;;;
|
|
|
583 ;;; 3) Some combinations of FTP clients and servers break and get out of sync
|
|
|
584 ;;; when asked to list a non-existent directory. Some of the ai.mit.edu
|
|
|
585 ;;; machines cause this problem for some FTP clients. Using
|
|
|
586 ;;; efs-kill-ftp-process can be used to restart the ftp process, which
|
|
|
587 ;;; should get things back in synch.
|
|
|
588 ;;;
|
|
|
589 ;;; 4) Some ftp servers impose a length limit on the password that can
|
|
|
590 ;;; be sent. If this limit is exceeded they may bomb in an
|
|
|
591 ;;; incomprehensible way. This sort of behaviour is common with
|
|
|
592 ;;; MVS servers. Therefore, you should beware of this possibility
|
|
|
593 ;;; if you are generating a long password (like an email address)
|
|
|
594 ;;; with efs-generate-anonymous-password.
|
|
|
595 ;;;
|
|
|
596 ;;; 5) Some antiquated FTP servers hang when asked for an RNFR command.
|
|
|
597 ;;; efs sometimes uses this to test whether its local cache is stale.
|
|
|
598 ;;; If your server for HOST hangs when asked for this command, put
|
|
|
599 ;;; (efs-set-host-property HOST 'rnfr-failed t)
|
|
|
600 ;;; in your efs-ftp-startup-function-alist entry for HOST.

649 ;;;
|

|
650 ;;; (efs-add-host <host-type> <host>)

|
|
|
654 ;;; completion. Some host types have regexps that can be used to
|
|
|
655 ;;; specify a class of host names as being of a certain type. Note
|
|
|
656 ;;; that if you specify a host as being of a certain type, efs does
|
|
|
657 ;;; not verify that that is really the type of the host. This calls
|
|
|
658 ;;; for caution when using regexps to specify host types, as an
|
|

|
|
|
676 ;;; efs is a "free" program. This means that you didn't (or shouldn't

677 ;;; have) paid anything for it. It also means that nobody is paid to

|
|
|
679 ;;; Therefore, please try to write your bug report in a clear and

|
721 ;;; Known bugs:
|
|
|
722 ;;; -----------
|
|
|
723 ;;;
|
|
|
724 ;;; If you hit a bug in this list, please report it anyway. Most of
|
|
|
725 ;;; the bugs here remain unfixed because they are considered too
|
|
|
726 ;;; esoteric to be a high priority. If one of them gets reported
|
|
|
727 ;;; enough, we will likely change our view on that.
|
|
|
728 ;;;
|
|
|
729 ;;; 1) efs does not check to make sure that when creating a new file,
|
|
|
730 ;;; you provide a valid filename for the remote operating system.
|
|
|
731 ;;; If you do not, then the remote FTP server will most likely
|
|
|
732 ;;; translate your filename in some way. This may cause efs to
|
|
|
733 ;;; get confused about what exactly is the name of the file.
|
|
|
734 ;;;
|
|
|
735 ;;; 2) For CMS support, we send too many cd's. Since cd's are cheap, I haven't
|
|
|
736 ;;; worried about this too much. Eventually, we should have some caching
|
|
|
737 ;;; of the current minidisk. This is complicated by the fact that some
|
|
|
738 ;;; CMS servers lie about the current minidisk, so sending redundant
|
|
|
739 ;;; cd's helps us recover in this case.
|
|
|
740 ;;;
|
|
|
741 ;;; 3) The code to do compression of files over ftp is not as careful as it
|
|
|
742 ;;; should be. It deletes the old remote version of the file, before
|
|
|
743 ;;; actually checking if the local to remote transfer of the compressed
|
|
|
744 ;;; file succeeds. Of course to delete the original version of the file
|
|
|
745 ;;; after transferring the compressed version back is also dangerous,
|
|
|
746 ;;; because some OS's have severe restrictions on the length of filenames,
|
|
|
747 ;;; and when the compressed version is copied back the "-Z" or ".Z" may be
|
|
|
748 ;;; truncated. Then, efs would delete the only remaining version of
|
|
|
749 ;;; the file. Maybe efs should make backups when it compresses files
|
|
|
750 ;;; (of course, the backup "~" could also be truncated off, sigh...).
|
|
|
751 ;;; Suggestions?
|
|
|
752 ;;;
|
|
|
753 ;;; 4) If a dir listing is attempted for an empty directory on (at least
|
|
|
754 ;;; some) VMS hosts, an ftp error is given. This is really an ftp bug, and
|
|
|
755 ;;; I don't know how to get efs work to around it.
|
|
|
756 ;;;
|
|
|
757 ;;; 5) efs gets confused by directories containing file names with
|
|
|
758 ;;; embedded newlines. A temporary solution is to add "q" to your
|
|
|
759 ;;; dired listing switches. As long as your dired listing switches
|
|
|
760 ;;; also contain "l" and either "a" or "A", efs will use these
|
|
|
761 ;;; switches to get listings for its internal cache. The "q" switch
|
|
|
762 ;;; should force listings to be exactly one file per line. You
|
|
|
763 ;;; still will not be able to access a file with embedded newlines,
|
|
|
764 ;;; but at least it won't mess up the parsing of the rest of the files.
|
|
|
765 ;;;
|
|
|
766 ;;; 6) efs cannot parse symlinks which have an embedded " -> "
|
|
|
767 ;;; in their name. It's alright to have an embedded " -> " in the name
|
|
|
768 ;;; of any other type of file. A fix is possible, but probably not worth
|
|
|
769 ;;; the trouble. If you disagree, send us a bug report.
|
|
|
770 ;;;
|
|
|
771 ;;; 7) efs doesn't handle context-dep. files in H-switch listings on
|
|
|
772 ;;; HP's. It wouldn't be such a big roaring deal to fix this. I'm
|
|
|
773 ;;; waiting until I get an actual bug report though.
|
|
|
774 ;;;
|
|
|
775 ;;; 8) If a hard link is added or deleted, efs will not update its
|
|
|
776 ;;; internal cache of the link count for other names of the file.
|
|
|
777 ;;; This may cause file-nlinks to return incorrectly. Reverting
|
|
|
778 ;;; any dired buffer containing other names for the file will
|
|
|
779 ;;; cause the file data to be updated, including the link counts.
|
|
|
780 ;;; A fix for this problem is known and will be eventually
|
|
|
781 ;;; implemented. How it is implemented will depend on how we decide
|
|
|
782 ;;; to handle inodes. See below.
|
|
|
783 ;;;
|
|
|
784 ;;; 9) efs is unable to parse R-switch listings from remote unix hosts.
|
|
|
785 ;;; This is inefficient, because efs will insist on doing individual
|
|
|
786 ;;; listings of the subdirectories to get its file information.
|
|
|
787 ;;; This may be fixed if there is enough demand.
|
|
|
788 ;;;
|
|
|
789 ;;; 10) In file-attributes, efs returns a fake inode number. Of course
|
|
|
790 ;;; this is necessary, but this inode number is not even necessarily
|
|
|
791 ;;; unique. It is simply the sum of the characters (treated as
|
|
|
792 ;;; integers) in the host name, user name, and file name. Possible
|
|
|
793 ;;; ways to get a unique inode number are:
|
|
|
794 ;;; a) Simply keep a count of all remote file in the cache, and
|
|
|
795 ;;; return the file's position in this count as a negative number.
|
|
|
796 ;;; b) For unix systems, we could actually get at the real inode
|
|
|
797 ;;; number on the remote host, by adding an "i" to the ls switches.
|
|
|
798 ;;; The inode numbers would then be removed from the listing
|
|
|
799 ;;; returned by efs-ls, if the caller hadn't requested the "i"
|
|
|
800 ;;; switch. We could then make a unique number out of the host name
|
|
|
801 ;;; and the real inode number.
|
|
|
802 ;;;
|
|
|
803 ;;; 11) efs tries to determine if a file is readable or writable by comparing
|
|
|
804 ;;; the file modes, file owner, and user name under which it is logged
|
|
|
805 ;;; into the remote host. This does not take into account groups.
|
|
|
806 ;;; We simply assume that the user belongs to all groups. As a result
|
|
|
807 ;;; we may assume that a file is writable, when in fact it is not.
|
|
|
808 ;;; Groups are tough to handle correctly over FTP. Suggestions?
|
|
|
809 ;;; (For new FTP servers, can do a "QUOTE SITE EXEC groups" to
|
|
|
810 ;;; handle this.)
