[rdiff-backup-users] Again: Socket trouble

[Troels Arvin]

Hello,

I'm having socket-related problems with rdiff-backup again.

Using v. 0.10.2 on both backup- and back'ed-up machines.

Backup-host is a FreeBSD 4.7-STABLE installation. Backed up host is a
Red Hat Linux 8.0 installation (with all fixes). Python versions: 2.2.2
on the FreeBSD host, v. 2.2.1 on the Linux host.

After a clean (full) backup and some nights without problems, I'm now
getting this again:

---------------------------------------------------------------------
Last backup dated Sat Jan 25 02:01:02 2003 was aborted, but we aren't
resuming it.

---------------------------------------------------------------------

I plan to look into Python soon, but as of now, I'm sort of lost. Does
anyone have a quick patch to simply ignore all socket files during
backups?
