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
56 $ wget ftp://bitreich.org/releases/geomyidae/geomyidae-$VERSION.tar.lz
57 $ lzip -d geomyidae-$VERSION.tar.lz
58 $ tar -xvf geomyidae-*.tar

67 .Pp
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.

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

375 .Ql host=frog.bog ,

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

620 [7|Hello You - Please enter your name|/hello.cgi?FROG.bog|frog.bog|70]
621 .Ed
622 .

629 Hello Christoph - welcome to FROG.bog
630 .Ed
631 .
632 .Pp
633 Dynamic CGI entries are similar to above except that the script
634 needs to create output as described in the

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