sendmail caused freebsd hang at boot time

fressbsd hang at the boot time when it came to the sendmail period.

the solution is to add one line into /etc/hosts like this:

192.168.28.26 bsd.local bsd


My unqualified host name (localhost) unknown; sleeping for retry

Make sure the host's names (including localhost) are defined in
/etc/hosts, and that /etc/hosts is being used in name resolution
(on 5.3 that would be configuration via nsswitch.conf(5)).

1996: SUMMARY: gethostbyaddr() failed

I solved the problem by adding back my ppp ip address into my hosts file.

There is no lookup for your IP address into a hostname. If you have
multiple interfaces or multiple addresses on one interface then you
must have a lookup for all the IP addresses.

The message there isn't an error - it's a warning. Just an annoying one :-)

Your system can't find all names for all interfaces.

Check for funny addresses with "ifconfig -a"
