I'm 99% sure they're generated by Courier-imap trying to access emails stored in my QNAP NAS.
The shared folder of my NAS is mounted in fstab with:
...
//192.168.168.10/mail /mnt/mail cifs username=virtual,password=miapw,iocharset=utf8,nos erverino,uid=5000,gid=5000,_netdev,mapchars 0 0
...
Ubuntu 10.10 running on VMWare with Postfix + Courier-IMAP + MySQL.
I've read about similar problems on the Net solved disabling the optimistic locking of cifs. This trick didn't solve my problem.
I used to see these and switched to using autofs. With autofs
a new connection is sought if the existing connection breaks.
It's likely that a temporary glitch is breaking the connection
and the traditional mount doesn't know how to reestablish it.
I tried but I received an error of mounting not allowed because wrong type of fs, "superblock" not valid (I'm translating so the messages could be sligthly different). dmesg says "autofs: called called with bogus options".
I'm trying to follow your logic. First you said you're getting "No response"
errors when you use mount. I mentioned autofs, and you said when you ran it
you received an error about "bogus options." I asked you to post the autofs
files, and you show an entry for /etc/fstab, which is used for mount and not
for autofs.
Hmmm. Are we talking about the same thing? Autofs is a daemon with its own
configuration files.
Hi, you are right, I didn't know autofs, I wrongly supposed it was a parameter like cifs ("type" of mount).
I've read something now about it, I followed some "How To" but...I failed!
If you can please guide me step by step considering that I already installed autofs, smbclient and smbfs.
I wanna reach my nas' mail share through /mnt/mail exactly like I already do with the usual mount described above.
I guess you should tell me exactly what to write inside auto.master and the other auto.xxx files.
It would really be better if you find how to make this work.
If you get stuck at a particular step or get an error message
I'd be glad to point you in the right direction.
You could start by posting the files you used and giving a
good description of what went wrong.
