I believe this is login.c where the the length of the FQDN of the host is greater than 16 characters. Rather than truncate the name, a reverse dns lookup is done and the IP address is printed. Another case is where the name is larger than the field and the reverse lookup (no reverse map or a dns config error) fails the you get "invalid hostname". Take a look at PR bin/4497 and the reply. If you make the change I suggest you set up syslog.conf with a line to log auth.info: auth.info /var/log/login.log --- Bob Beer <r-beer@onu.edu> Ohio Northern University, Academic Computer Services, Ada, OH 45810 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
