34 .Sh DESCRIPTION
35 .Nm
36 is a daemon for serving the protocol specified in
37 .Em RFC 1436
38 (Gopher).
39 Under 1000 lines of C by design, it is lightweight yet supports
40 dynamic content, automatic file/directory indexing, logging and privilege
41 separation.
42 .
43 .Sh IMPLEMENTATION
44 Installation is straightforward: grab the zipped tar file, expand it in
45 an appropriate temp directory, change to the
46 .Qq Pa "../geomyidae-x.xx"
47 directory, tweak the Makefile if desired (installs in
48 .Qq Pa "/usr/bin"
49 by default), then run the
50 .Qq Ql "make ; make install"
51 commands.
52 The resulting executable should be run by root.
53 .
54 .Ss Basic Installation and Startup
55 .Bd -literal -offset indent

68 Use whatever gopher client you like (ie. sacc) to browse:
69 .Bd -literal -offset indent
70 $ sacc gopher://localhost
71 .Ed
72 .
73 .Ss Running
74 .Nm
75 should normally be started by root, although it can be started
76 by a regular user provided that the base directory and its contents are owned
77 by the same user.
78 .Nm
79 will only serve content within the base directory
80 tree and will drop privileges to the
81 .Fl u Ar user
82 and
83 .Fl g Ar group
84 values if set.
85 See
86 .Sx OPTIONS
87 below for specifics.
88 Launching
89 .Nm
90 automatically is best done via a UNIX
91 run-time (rc.d) script; several sample rc.d scripts are included in the
92 .Nm
93 source archive.
94 Logging in
95 .Nm
96 can be done through either logfiles or syslog.

217 Activate gopher TLS and use the private key
218 .Ar keyfile
219 and the public key
220 .Ar certfile
221 for TLS connections (if the feature is compiled in.) See
222 .Sx ENCRYPTION ONLY
223 support below.
224 .El
225 .
226 .Sh FORMATTING
227 Structured Gopher space(s) can be created with
228 .Nm
229 through the use of special indexing files of the form
230 .Pa <name>.gph
231 which, if present,
232 .Nm
233 uses to format and/or filter the contents of the base directory
234 .Po
235 .Pa /var/gopher
236 by default
237 .Pc
238 and create gopher menus.
239 However, index files are
240 .Em not
241 required: if no
242 .Pa index.gph ,
243 .Pa index.cgi
244 or
245 .Pa index.dcgi
246 file is found,
247 .Nm
248 simply lists the directory contents in alphanumeric order.
249 In addition, a directory can utilize
250 multiple index files to create a layered gopher environment without the
251 use of sub-directories: ie.\&
252 .Pa pictures.gph ,
253 .Pa music.gph
254 and
255 .Pa documents.gph
256 could be "directories" within
257 .Pa main.gph ,
258 yet all reside in
259 .Pa /var/gopher
260 along with their respective files (*.jpg, *.mp3, *.pdf for example).
261 .
262 .Ss Anatomy of an index.gph file
263 A gph file consists of informational text and links.
264 A link has the form:
265 .Pp
266 .Dl [ Ar <type> Ns | Ns Ar <desc> Ns | Ns Ar <path> Ns | Ns Ar <host> Ns | Ns Ar <port> ]
267 .Pp
268 where,
269 .Bl -tag -width "<XXXX>"
270 .It Ar <type>
271 A valid gopher Item Type.
272 .Pp
273 Some common Gopher Types as defined in
274 .Em RFC 1436 :
275 .
276 .Bl -tag -width "XX" -compact
277 .It Cm 0
278 Item is a file.
279 .It Cm 1
280 Gopher directory.
281 .It Cm 3
282 Error.
283 .It Cm 7
284 Item is an Index-Search server.
285 .It Cm 8
286 Item points to a text-based telnet session.
287 .It Cm 9
288 Binary file.
289 Client reads until TCP connection closes!
290 .It Cm g
291 GIF format graphics file.
292 .It Cm I
293 Indeterminate image file.
294 Client decides how to display.
295 .El
296 .Pp
297 In addition,
298 .Nm
299 provides these:
300 .Bl -tag -width "XX" -compact
301 .It Cm h
302 Item is a hypertext (HTTP) link.
303 .It Cm i
304 Informational Item (used for descriptive purposes).
305 .El
306 .Pp
307 Unknown file types default to Type
308 .Qq Cm "9"
309 (binary).
310 .
311 .It Ar <desc>
312 Description of gopher item.
313 Most printable characters should work.
314 .
315 .It Ar <path>
316 Full or relative path to gopher item (base value is
317 .Qq Pa "/" ) .
318 Use the
319 .Qq Pa "Err"
320 path for items not intended to be served.
321 .
322 .It Ar <host>
323 Hostname or IP hosting the gopher item.
324 Must be resolvable for the intended clients.
325 If this is set to
326 .Qq Cm "server" ,
327 the server's hostname is used.
328 .
329 .It Ar <port>
330 TCP port number (usually 70).
331 If this is set to
332 .Qq Cm "port" ,
333 the default port of the server is used.
334 .El
335 .
336 .Pp
337 Note:
338 .Nm
339 doesn't require "informational" text to be formally typed as
340 .Ql "[i|...]" ;
341 any line
342 .Em not
343 beginning with
344 .Ql "\(lB"
345 is treated as informational, greatly simplifying the formatting of
346 .Pa index.gph
347 files.
348 If you want to display some informational text beginning with
349 .Ql "\(lB"
350 you can use the special case of an empty item type.
351 .Ql "[|[some link"
352 will be shortened to
353 .Ql "[some link" .
354 For dynamically generated content it may be desirable to either formally type
355 informational text or run it through a filter to prepend
356 .Ql "[|"
357 - \.ie
358 .Ql "sed 's,^[,[|&,'" .
359 .Pp
360 Note 2: You can escape a pipe
361 .Pq Ql "\(ba"
362 character in for example a
363 .Cm <desc>
364 field by prepending a slash ("\\").
365 .Pp
366 Note 3: The gph parser is very forgiving.
367 If the link structure is not parsed correctly, then the original line is printed.
368 .
369 .Ss index.gph Example
370 A
371 .Pa root.gph

373 .Ql host=frog.bog ,
374 .Ql port=70 .

428 .Sh DYNAMIC CONTENT (gopher CGI)
429 There are two options provided for dynamic content creation and a special
430 case: standard CGI
431 .Pq Pa ".cgi" ,
432 dynamic CGI
433 .Pq Pa ".dcgi" ,
434 and HTTP compatibility mode.
435 Despite the names, all three can accept input and generate dynamic content;
436 the only difference is that dcgi re-formats it's output so it appears to
437 the server as a standard
438 .Nm
439 index
440 .Pq Pa ".gph"
441 file.
442 This makes the creation of on-the-fly gopher directories much easier (see examples).
443 All scripts must be under the gopher root directory and be executable by the same
444 .Ar "user:group"
445 running
446 .Nm .
447 Consequently, it is best to use the
448 .Fl u
449 and
450 .Fl g
451 server options to avoid running as root.
452 .Pp
453 Executed scripts get the full I/O of the socket bound to stdin and stdout.
454 You are thus able to write long-lasting streaming services.
455 Radio or TV stations over gopher are possible that way.
456 .Pp
457 Both
458 .Pa ".cgi"
459 and
460 .Pa ".dcgi"
461 scripts have the same argument call structure (as seen by
462 .Nm ) :
463 .Pp
464 .Dl Ic executable.[d]cgi Ar search Ar arguments Ar host Ar port Ar traversal Ar selector
465 .Pp
466 where:
467 .Bl -tag -width "XXXXXXXXX" -compact
468 .It Ar search
469 Query string (type 7) or "" (type 0).
470 .It Ar arguments
471 String behind "?" in selector or "".
472 .It Ar host
473 Server's hostname ("localhost" by default).
474 .It Ar port
475 Server's port ("70" by default).
476 .It Ar traversal
477 Remaining path from path traversal in REST case.
478 .It Ar selector
479 Raw selector or full req (See HTTP compatibility mode.)
480 .El
481 .Pp
482 All terms are tab-separated (per gopher protocol) which can cause some
483 surprises depending on how a script is written.
484 See the CGI file (included in the
485 .Nm
486 source archive) for further elaboration.
487 .Pp
488 For a special REST path case for the arguments, see the CGI file for the
489 description.
490 .Pp
491 QUIRK: The original gopher client tried to be too intelligent.
492 It is using gopher+ when you request some resource.
493 When "search" is just the value "+", "!", "$" or empty,
494 .Nm
495 will display a gopher+ redirect instead of invoking the script.
496 Be careful to design your search script so the user is unlikely to enter those values.
497 The designers of gopher+ did not think of classic gopher to survive.
498 It survived gopher+.
499 .Pp
500 Additionally to the above arguments several environment variables are set.
501 Only the programmatically relevant variables are listed here.
502 For further information, see ind.c:setcgienviron() in the geomyidae
503 source code.
504 .Bl -tag -width "REMOTE_ADDR , REMOTE_HOST" -compact
505 .It Ev PATH_INFO
506 Traversal (See above.)
507 .It Ev PATH_TRANSLATED
508 Absolute path to script.
509 .It Ev QUERY_STRING
510 Arguments (See above.)
511 .It Ev REMOTE_ADDR , REMOTE_HOST
512 IP of the client
513 .It Ev SCRIPT_NAME
514 Script which is executed.
515 .It Ev SERVER_NAME
516 Server's hostname.
517 .It Ev SERVER_PORT
518 Server's port.
519 .It Ev GOPHER_SELECTOR
520 Raw gopher selector
521 .It Ev GOPHER_REQUEST
522 Raw gopher selector
523 .It Ev GOPHER_SEARCH
524 Search (See above.)
525 .It Ev GOPHER_SCRIPT_FILENAME
526 Absolute path with script which is executed.
527 .It Ev GOPHER_DOCUMENT_ROOT
528 Base root for serving files.
529 .It Ev SERVER_LISTEN_NAME
530 Ip the server received the connection on.
531 .It Ev HTTPS , GOPHERS
532 Set, if TLS is used.
533 .El
534 .
535 .Ss The REST path handling
536 If a client requests a path in a selector, which has no corresponding
537 file or path found,
538 .Nm
539 will try to traverse from the
540 .Fl b Ar base
541 path until a path component / directory is not found.
542 Then
543 .Nm
544 tries to find some index.dcgi or index.cgi file in the last existing directory.
545 If this is found and the index files are executable,
546 .Nm
547 will execute them using the traversal and
548 .Ev PATH_INFO
549 parameter and environment variable being set to the rest path.
550 .Bd -literal -offset indent
551 Selector: /some/v1/service/add/something?args=value
552 -> /some/v1/service exists
553 -> /some/v1/service/index.dcgi exists
554 -> /some/v1/service/index.dcgi "" "args=value" $host $port
555 "/add/something" "/some/v1/service/add/something?args=value" is called
556 .Ed
557 .
558 .Ss HTTP compatibility
559 For maximum flexibility in case someone sends a HTTP request to gopher,
560 .Nm
561 supports a special case of CGI.
562 See this example:
563 .Bd -literal -offset indent
564 Client request: GET /some/path HTTP/1.1
565 -> /GET exists and is executable
566 -> /GET "" "" $host $port "" "GET /some/path HTTP/1.1" is called
567 .Ed
568 .Pp
569 This allows for example simple scripts for icecast upload compatibility
570 or handling transparent HTTP right next to gopher, getting TLS for free.
571 .
572 .Ss Some CGI Examples
573 Note: these are a very simple examples with no fitness checks with respect
574 to safety/security.
575 .Pp
576 ex.
577 .Pa uptime.cgi - standard CGI, no queries
578 .
579 .Bd -literal -offset indent
580 #!/bin/sh
581 # uptime.cgi - prints system uptime(1)
582 /usr/bin/uptime
583 exit 0
584 .Ed
585 .
586 .Pp
587 Call the above with the following index.gph entry:
588 .Pp
589 .Dl [0|System Uptime|/uptime.cgi|frog.bog|70]
590 .Pp
591 A search query request must have an item Type of
592 .Qq Cm "7"
593 to be called from an
594 .Pq index.gph
595 file.
596 It also needs a
597 .Qq Cm "?\&"
598 suffix in the
599 .Ar <path>
600 field:
601 .Pp
602 ex.
603 .Pa hello.cgi - standard CGI with query
604 .
605 .Bd -literal -offset indent
606 #!/bin/sh
607 # hello.cgi - welcome user
608 NAME=$1

611 echo Hello $NAME - welcome to $HOSTNAME
612 exit 0
613 .Ed
614 .
615 .Pp
616 Call the above with the following index.gph entry:
617 .Bd -literal -offset indent
618 [7|Hello You - Please enter your name|/hello.cgi?FROG.bog|frog.bog|70]
619 .Ed
620 .
621 .Pp
622 And do a simple

624 query (note the inserted TAB):
625 .Bd -literal -offset indent
626 % snarf "gopher://frog.bog/7/hello.cgi?FROG.bog[TAB]Christoph" -
627 Hello Christoph - welcome to FROG.bog
628 .Ed
629 .
630 .Pp
631 Dynamic CGI entries are similar to above except that the script
632 needs to create output as described in the
633 .Sx FORMATTING
634 section:

767 .Bd -filled
768 .Nm
769 started as a Linux/BSD port of the Plan 9 gopherd_P9 server.
770 Originally called gopherd_BSD, the name was later changed to
771 .Qq Em Geomyidae
772 (latin), the taxonomic family of burrowing rodents known as
773 .Qq Em "pocket gophers"
774 which are in fact the true gophers.
775 Due to inconsistencies and the UNIX culture, the name was changed to lowercase in 2010.
