I installed Solaris2.7 on four machines.
two of them are in the inner network of the firewall and the other two are in the dmz.
I look at /var/log/syslog on one of the machines on the dmz and I found there that message:"Unable to qualify my own domain name...". (by sendmail)
I don't care about the message but my problem is that in this log there were these messages for all other three machines. The IP that appeared there was the real IP followed by two more numbers separated by dots. Can someone please explain this?
