No firewalls blocking amanda = no in line/software firewalls, access lists, portsentry, linux route blocking, or tcp wrappers protecting the client and vice versa the server. However, I will recheck everything because it never hurts. To note: When I relocated the client server to the backup server's network, detection and backups worked without a hitch.

The connections needed are described > in the amanda document "PORT.USAGE To test out my hypothesis on firewalls etc.., (assuming Amanda was installed correctly) I established a client machine with iptables blocking all ports, including ICMP, syn, fin, etc. Amcheck reported host not found. I then opened the ONE port 10080 UDP on the client via iptables, and amcheck reported host found + it backed it up. I have read the PORTS.USAGE documentation and have not found anything in the documentation that gave me a light bulb as to this problem. My only assumption is that UDP is not reliable over multiple routers for amanda to work.. It's just an Assumption. Keep 'em coming! Tano > > -- > Jon H.
