Can anyone tell me of an available internet cafe software?
what can I use to administrate an internet cafe with all machines running linux?
there is no specific "internet cafe" software.
you can look into NIS/NIS+ and NFS for shareing accounts and resourceses.
look into some sort of imaging software so you can reinstall each machine nightly or weekly or how ever. but you will deffinetly want to find something to make bringing a new PC into the network fast.
all depends on what your actually trying to do.
