I'm facing the very same issue with version 6.0.8 under SLES 11 SP1.
I have just corrected the "statistics not shown" (permission problems, wrong/inexistent auth keys, syslog not properly configured) problem which I thought related to this but it seems not.
I have sysstat package installed and I'm running syslog. I did a ./syslog restart and it appears to be running fine. After that I run this
Code:
ssh -i .ssh/zimbra_identity -o strictHostKeyChecking=no zimbra@mail.unitan.net
but server did not show any answer
Any idea will be much appreciated,
Pancho
