After long consideration, Jos Vissers uttered the following: > Hello, > > Can somebody please explain how to increase the user login name length > limit.

Almost there, but not quite. You grab the sources (ALL of them), edit UT_NAMESIZE in .../include/utmp.h and rebuild everything. After the installation you might want to remove /var/run/utmp (i think) and reboot. Remember that xterm probably will also need recompiling! So will anything else that even looks at the utmp! That's because changing UT_* changes sizeof(struct utmp) and sizeof(struct lastlog) which is kinda important. > > Is it possible at all to increase this beyond 8 and if so, how? Sure! I've changed UT_HOSTSIZE to 48 for instance.

Hackish evil and rude is close to the mainstream sense of `evil'. --Jargon file, version 4.0.0 [edited]
