How to have sshd log IP numbers instead of reverse lookups

[James Long]

I was looking at /var/log/auth.log and saw an entry of the form:

Nov 24 18:41:37 ns sshd[58083]: error: PAM: authentication error for username from example.com

I wish to have an IP number logged where sshd has instead logged
'example.com'

Reading sshd's man page and sshd_config's man page, I don't find any
way to control this.

Since 'example.com' could have multiple IP numbers, how can I change 
sshd's configuration to log the IP number from whence the 
authentication error originated?


Thanks!
