addr 0.0.0.0: hostname lookup failed

The amdump and amcheck commands may display this error.

Template:Troubleshooting Solution

Check the amandad debug logs on the client. For example: /tmp/amanda/amandad.<Datestamp>. Example of log messages:

amandad: time 0.000: dgram_send_addr: sendto(0.0.0.0.566) failed:
Invalid argument
amandad: time 0.003: sending REP packet:

Amanda 2.4 REP HANDLE 001-A8850608 SEQ 1152114891
ERROR [addr 0.0.0.0: hostname lookup failed]

One of the possible reasons can be using inetd in IPv6 environment on a linux system. If this is the case, then

  • use xinetd instead of inetd services; and
  • set protocol field to tcp46 in xinetd or inetd service entry. See also How To:Run Amanda Over IPv6.
