Compiling and installing Gophernicus ==================================== Gophernicus requires a C compiler but no extra libraries aside from standard LIBC ones. Care has been taken to use only standard POSIX syscalls so that it should work pretty much on any *nix system. To compile and install run: $ git clone https://github.com/kimholviala/gophernicus.git $ cd gophernicus $ make $ sudo make install That's it - Gophernicus should now be installed, preconfigured and running under gopher:///. And more often than not, It Just Works(tm). If gopher links don't seem to work you may need to configure your public hostname explicitly in whatever config file Gophernicus is using. By default Gophernicus serves gopher documents from /var/gopher although that can be changed by using the -r parameter. To enable virtual hosting create hostname directories under the gopher root and make sure you have at least the primary hostname (the one set with -h ) directory available (mkdir /var/gopher/$HOSTNAME). Compiling with TCP wrappers =========================== Gophernicus uses no extra libraries... well... except libwrap (TCP wrappers) if it is installed with headers in default Unix directories at the time of compiling. If you have the headers installed and don't want wrapper support, run 'make generic' instead of just 'make', and if you have wrappers installed in non-standard place and want to force compile with wrappers just run 'make withwrap'. For configuring IP access lists with TCP wrappers, take a look at the files /etc/hosts.allow and /etc/hosts.deny (because the manual pages suck). Use the daemon name 'in.gophernicus' to make your access lists. Running with traditional inetd superserver ========================================== If you want to run Gophernicus under the traditional Unix inetd, the below line should be added to your /etc/inetd.conf and the inetd process restarted. gopher stream tcp nowait nobody /usr/sbin/in.gophernicus in.gophernicus -h The Makefile will automatically do this for you if you have the update(1) script installed, which is the usual case in most current flavors of Linux and BSD. Compiling on Debian Linux (and Ubuntu) ====================================== The above commands work on Debian just fine, but if you prefer having everything installed as packages run "make deb" instead of plain "make". If all the dependencies were in place you'll end up with an offical-looking deb package in the parent directory (don't ask - that's just how it works). And instead of "sudo make install" you should just install the deb with "dpkg -i ../gophernicus_*.deb" after which It Should Just Work(tm). If you need TCP wrappers support on Debian/Ubuntu, please install libwrap0-dev before compiling. Cross-compiling =============== Cross-compiling to a different target architecture can be done by defining HOSTCC and CC to be different compilers. HOSTCC must point to a local arch compiler, and CC to the target arch one. $ make HOSTCC=gcc CC=target-arch-gcc Shared memory issues ==================== Gophernicus uses SYSV shared memory for session tracking and statistics. It creates the shared memory block using mode 600 and a predefined key which means that a shared memory block created with one user cannot be used by another user. Simply said, running in.gophernicus under various different user accounts may create a situation where the memory block is locked to the wrong user. If that happens you can simply delete the memory block and let Gophernicus recreate it - no harm done: $ sudo make clean-shm Porting to different platforms ============================== If you need to port Gophernicus to a new platform, please take a look at gophernicus.h which has a bunch of HAVE_* #defines. Fiddling with those usually makes it possible to compile a working server. If you succeed in compiling Gophernicus to a new platform please send the patches to me so I can include them into the next release.
