What kind of trouble?
Recovering amanda configuration
General networking
- Issue
- Amanda server and backup client are connected to the Internet via ADSL. It seems that when Amanda on the backup client does a DNS lookup for my Amanda server, it sees something like:
[email protected]
which is generated by the ISP. Since the machine has a static IP address, the really-long-and-annoying-hostname shouldn't change. How to use backup server's hostname actual hostname (amanda.mydomain.com) instead of the long ISP name?
- Solution
- Define the IP address in the hosts file (/etc/hosts) on the backup client
XXX.XXX.XXX.XXX amanda.mydomain.com
- Change the name lookup order in /etc/nsswitch.conf file to
hosts: files dns
The lookup order, eg. files dns (and/or ldap, nis, ...) so that hosts file is searched before name servers.
Reality Check Your Tape Drive
You can use a low level command to check the status of your tape drive, substituting the device name of your drive:
On FreeBSD:
mt -f /dev/rsa0 status
