I have a centos box using kernel 2.6.9-42.0.2.ELsmp that had a samba
server running very nicely until 2 days ago. Out of the blue, users
can't access any shares. We have 5 users and 6 shares, one of which is
an MS access database that gets the most use. I thought the smbpasswd
database may be corrupt so I replaced it with a backup, but no go. I
deleted the smbpasswd database, re-added users, that didn't work either.
Checking a users samba log, I found this series of errors when trying to
get to any samba share:
[2007/12/19 13:16:15, 0] auth/pampass.c:smb_pam_error_handler(73)

The smbd.log shows this:
[2007/12/19 13:16:08, 0] lib/util_sock.c:get_peer_addr(1232)
getpeername failed. Error was Transport endpoint is not connected
I can 'smbclient -L' to the workstations, and all other services (httpd,
sendmail, squid) are running as usual. I can smbmount from the linux
machine to a workstation and use the files in the shares, but can't get
from teh workstations to the linux box. From my limited experience, it
seems authentication is whacked, but I can't flesh it out. Any help is
appreciated.
