Heh, I've just been working on this on my linux setup...
The answer is yes you can set up you own login server on linux, but the current guides don't cover it for Linux, presumably as the authors wanted to use the public login server. First you must download the right dependencies for your distro from
http://eqemu.github.io - I use Debian 7 32 bit so used
http://eqemu.github.io/ubuntu_LoginServerCrypto_x86.zip
Unzip and put the two files in the dependencies folder in your source.
When I ran cmake I didn't get any config choices at all, so I had to hand edit CMakeCache.txt and found the
Code:
EQEMU_BUILD_LOGIN:BOOL=OFF
and changed to
Code:
EQEMU_BUILD_LOGIN:BOOL=ON
then re-ran make to compile. See how you go with that, at the time of writing my code won't compile, but that's for a different reason that's unrelated.
It is worth mentioning what version of linux you are using if you require further support, as the answers may very well depend on that.
