Hello,
I have a problem using csync. After a few actions, including removing a
#comment from csync2.cfg and changing the cron table, csync2 does not
sync any more and yields the unuseful error message "'Format-error while
receiving data"
running csync2 on host leihnix6h1 leads to the following error message:

running on leihnix5h1 however leads to "all OK":

csync2 -T on leihnix6h1:
X leihnix5h1-eth1 leihnix6h1-eth1 /etc/cron.d/csync2
L leihnix5h1-eth1 leihnix6h1-eth1 /etc/puppet/manifests/hosts.pp
L leihnix5h1-eth1 leihnix6h1-eth1 /etc/puppet/manifests/nodes.pp
For the cron.d/csync2 an auto-resolve rule is in place, however it
doesn't work. (I don't know why).
Using csync2 -f /etc/cron.d/csync2 didn't help it, either.
My config file is:
> nossl 172.31.* 172.31.*;
> nossl leihnix*h* leihnix*h*;

Do you have an idea how to circumvent the "format error" ?
