Hi Both computers are on the private network. 192.168.1.100 is the amanda server and 192.168.1.47 is the client. $amcheck DailySet1 gave this error
Amanda Backup Client Hosts Check -------------------------------- ERROR: 192.168.1.47: [addr 192.168.1.100: hostname lookup failed] Client check: 1 host checked in 0.031 seconds, 1 problem found I tried to add "192.168.1.47 client" to the /etc/hosts file and got the similar error message. Both machines are using redhat8.0 amd amanda 2.4.3. Thanks for your help Qian
