>Description:
skkserv core dumps when gethostbyname() failed. 
I think it is caused by misconfiguration of nsswitch.conf or hosts,
but core dump is not good.

>How-To-Repeat:

Replace the `hosts:' line in nsswitch.conf with `hosts: files'.
Remove your host name in hosts.
Run /usr/pkg/etc/rc.d/skkserv.sh.

>Fix:
Here is the patch.
