I have two servers next to each other in a data centre. I use cron jobs to back up data each way betwen the two, using rsync. In the course of this year I have upgraded both to amd64/9.2, but leaving all the cron/rsyncd.conf etc. config in place. I checked that everything ran normally back in July, but now I find /var/log/cron is full of lines like this:
Nov 14 22:02:00 trafalgar cron[3913]: (CRON) pam_authenticate failed (System error) hosts allow is set in a [global] module to include the address range that encompasses both machines in both machines'.rsyncd.conf files. Where to start? -- Steve Blinkhorn <st...@prd.co.uk>
