exactly same problem.
I just updated some email data. After that, I couldn't login to
my imap accounts. Login by ssh also failed for every user with:
:~# ssh_exchange_identification: Connection closed by remote host
Rebooting the machine failed. The remote-hand-on by data center also...
tomorrow (Sunday) I've to get up early ..
driving to the datacenter in Frankfurt/Main
worked always fine upto now
could it be that if you perform many changes in near time, the
"systemmanger" (the smart-guy who changes the passwd and
shadow file) gets little bit "confused" by doing his job?
otherwise I cannot explain to myself what there was going wrong.
but the most curious thing is, that all this problems happend coextensive.
hoping my forum members are goint to excuse the offline time
// STATUS UPDATE: sunday 1pm
machine is on the net again.
Had to restore passwd, shadows and group
thx for the tutorial "how to knoppix with lvm and raid" - was a real help to me!
if I can help tracing the failure to his roots, I will mail all needed logs to ispconfig mods.
best, give me some commands like: tail -5000 /var/log/auth.log > auth.log.txt
thereby, I can collect all you want
I'm on Debian etch,
/root/ispconfig and /home/adminispconfig are the dirs
what else attracts my attention:
- the file local-host-names lost settings beyond "#### MAKE MANUAL ENTRIES BELOW THIS LINE! ####"
- the shadow file was cropped. It only contents some webxx_* accounts. System account weren't there anymore.
