##############The bb-hosts file entry is as follows:
page solaris Solaris
192.168.X.X solaris # Name:"SOLARIS" dns nis ntp telnet pop3 pop3s imap imaps
You are not using FQDN.
Try (as the xymon user on the xymon host)
dig @solaris solaris
You may not be resolving correctly. Confirm /etc/resolv.conf is correct
Try adding your domain to bb-hosts
192.168.X.X solaris.example.com # Name:"SOLARIS" dns nis ntp telnet pop3 pop3s imap imaps
Also try removing ' Name:"SOLARIS" ' (I don't think that will matter though)
