I built it from ports with no problem. I'll attach my
/usr/local/etc/amanda/python/amanda.conf file if it will help.
Getting the remote login to the systems you want to backup is a
little tricky; I use ".amandahosts" instead of .rhosts, but it's the
same issue. Huh, in this client machine's ~operator/.amandahosts I'm
allowing the amanda server (with the tape drive) in, it runs as
operator on the server, sisyphus.shenton.org:
sisyphus.shenton.org
The other part is getting the /etc/services and /etc/inetd.conf
configured, but that's easy enough. /etc/services comes with the
amanda ports already listed. Here's my part of the client's
inetd.conf:
amanda dgram udp wait operator /usr/local/libexec/amanda/amandad amandad
Here's my amanda.conf; you'll have to modify the tape parameters for
your tape drive:
# $Id: amanda.conf,v 1.5 2000/02/22 13:19:19 operator Exp $
