    - -For some of the indexes to work you must generate the necessary -databases... - -Vh-man2html's manwhatis CGI-script uses the /usr/man/whatis file to build -a man page index. Caldera 1.0 normally builds the /usr/man/whatis every -morning at 3:21am. If this job has never been run (perhaps because -you turn your machine off at night), you can build it by becoming the -root user and entering: - - /usr/sbin/makewhatis /usr/man /usr/X11R6/man /usr/local/man - -WARNING: makewhatis in Caldera 1.0 takes about 30 minutes on my -486DX66. I have a modified version of makewhatis so that it does -exactly the same job in only 1.5 minutes. My modified version is now -available as part of man-1.4g (man-1.4g.tar.gz) and above: - - ftp://sunsite.unc.edu/pub/Linux/system/Manual-pagers - -To use the Glimpse full text searching, you will need to install -glimpse in /usr/bin. Redhat rpm users can get glimpse from - - ftp://ftp.redhat.com/pub/non-free/glimpse-3.0-1.i386.rpm - -The glimpse home ftp site is cs.arizona.edu. N.B. glimpse is not -freely redistributable for commercial use, I'd be very interested in a -more liberal alternative. Having installed glimpse, you will need to -build a glimpse index in /var/man2html. This doesn't take too long - -about 3 minutes on my 486DX2/66 16MB machine. As root do: - - /usr/bin/glimpseindex -z -H /var/man2html /usr/man/man* /usr/X11R6/man/man* \ - /usr/local/man/man* /opt/man/man* - chmod ugo+r /var/man2html/.glimpse* - -The -z option causes glimpse to apply any filters (for decompression etc) -specified in /var/man2html/.glimpse_filters. - -This could be set up as a cron job in /etc/crontab, e.g. (the following -must be all on one line): - - 21 04 * * 1 root /usr/bin/glimpseindex -z -H /var/man2html /usr/man/man* - /usr/X11R6/man/man* /usr/local/man/man* /opt/man/man* ; - chmod +r /var/man2html/.glimpse* - -If you don't want to use glimpse you can edit the man.html file that -the package installs in /home/http/html/man.html, and remove the -references to full text searches and glimpse. This file can also be -edited to include any local instructions you might wish to include. - -The scripts may generate errors to the httpd error log -/var/log/httpd/error_log. The man binary (used to obtain the man-path -by some of the scripts) seems to always think it's talking to a tty, -and tries to obtain the screen size, resulting in the following error -log entries: - - TIOCGWINSZ - failed : Bad file number - -To serve man pages to remote hosts, all that is required is a httpd -daemon that sets the environment variable SERVER_NAME correctly. - -END OF QUICK START INSTRUCTIONS -------------------------------- - -Vh-man2html was was written by Richard Verhoeven (NL:5482ZX35) at -the Eindhoven University of Technology (Email: rcb5@win.tue.nl). The -original source is available from his web page at: - - http://wsinwp01.win.tue.nl:1234/maninfo.html - -There are other man2html programs around - Richard's page has links to -several of them. Richard's man2html has some useful features for -Caldera/RedHat Linux - - - Works from the troff/nroff source pages. - With linux we almost always have the man source. - Doesn't have to run man+tbl+eqn+nroff to generate output. - Because man isn't run, no catman pages are generated. - Accurate - doesn't have to guess from the man output. - Does tables (eg man ascii) (but doesn't do eqn - few pages use eqn). - Written in C - efficient speed/memory usage. - Fast enough not to need a cache. - Intelligent - Makes good guesses on where to find pages. - Creates links for man pages and include files. - -Richard's original program copes with pages formatted with the man -macros. I've enhanced it by adding translations for the mandoc macros -used in the BSD man pages. BSD mandoc pages in Caldera/Redhat -include Mail, ftp, telnet, rlogin, and lpr and other printer man -pages - so they're pretty important. - -I don't have any documentation on the mandoc macros, so I've had to -guess what they intend, by looking at man source, man output and the -gnroff macro definitions. I've tested it on all the BSD mandoc pages -in Section 1 that I could find. It works reasonable well. There are -still minor formatting glitches to do with punctuation placement. -I checked the BSD mandoc with weblint, e.g. in tcsh/csh - - foreach i ( `egrep -l '^\.Bl' /usr/man/man1/* /usr/man/man8/*` ) - /home/httpd/cgi-bin/man2html $i > tmp/`basename $i` - end - weblint tmp/* - -For broader testing: - - find /usr/man/man* -name '*.[0-9]' \ - -printf "echo %p; /home/httpd/cgi-bin/man2html %p |weblint -x netscape -\n" \ - | sh \ - |& tee weblint.log - -If you want to sample the spectrum of mandoc translation, look at -any of the pages the above grep locates, telnet, lpc, and mail -are good examples. - -For full details of my modifications to man2html.c see the patch -included in the source archive. - -Here's a summary of the rpm's components: - - 1) man.html - Main page or access to man2html and man indexes. - 2) man2html - CGI binary that converts man pages to html. - 3) manwhatis - CGI script for a name and synopsis index organised - by manual section - 4) mansec - CGI script for a name only index for each section. - 5) mansearch - Glimpse full text searching. - 6) mansearch.html - Main page or access to man2html and man indexes. - 7) netscape-man - Front end that starts, or talks to, a running netscape. - 8) /var/ma2html - Cache directory for indexes and glimpse indexes. - -All my scripts are written in awk. In detail... - -The manwhatis script creates section contents html files by looking -for whatis files along the man path. Each whatis entry is translated -to a man2html link. Manwhatis caches it's output in -/var/man2html/whatis-[0-9].html. The cache will be regenerated if any -whatis file in the man path is updated (eg touch /usr/man/whatis). - -The mansec script lists the names of all manual pages for a given -section by using find on the man path. It caches its output in -/var/man2html/manindex-[0-9].html. The cache will be regenerated if -any associated man[0-9] directory in the man path is updated. - -The mansearch script uses glimpse to get back a list of files and -matches which it links back to the actual man pages. The mansearch -script is not pure awk. It's starts out as a shell script to ensure -that the parameters are safely passed to awk. I think it's secure, -but I'm not a cgi script expert. - -To build and install man2html, the scripts, and man.html from the -source archive - edit the Makefile and then: - - make install - -To build binary and source rpms, placing them under /usr/src/... - - make rpm - -SECURITY --------- - -I've modified the man2html C code so that it checks all client input -parameters for length and characters that need escaping. - -Man2html will only return man or mandoc files resident in the man -hierarchy defined in /etc/man.config. - -When man2html generates references to include files they are in the -form file: on the CLIENT host, not the server. - -The parameters to the decompression programs are checked for any -nasties. - -It is still possible for the contents of a man page to over-run -man2html's memory - so I guess a hacker might try to get you to -install a bogus man page in order to get man2html to do something -nasty. - -The scripts check their parameters for anything suspicious. - -The scripts and program write suspicious requests to stderr - so they -can be found in web server log files. - -CREDITS -------- - -See the man page man2html.8 for credits. - ---------------- - -My modifications, packaging and scripts are copyright (c) 1996 -Michael Hamilton (michael@actrix.gen.nz).
