FreeBSD-3.0-current
>Description:
bootpd gave error:
"Can not get my IP address"
Built in debugging code revealed that
hostname isdn-kukulies.dialup.rwth-aachen.de
was longer than 32 chars.
>How-To-Repeat:
name your host to something longer than 32 chars
and enable bootpd in /etc/inetd.conf. kill -HUP inetd.
>Fix:
affects libc and probably kernel. I don't know
if increasing the value of SYS_NMLN to 64 would cure
the problem for all possible hostnames in the future
but it would decrease the likelyhood that it happens
to someone who runs bootpd and has a long hostname.
