[Samba] intermittent failure of ability to connect to samba share from win (NT/2k) client
First, my installation is samba 2.2.8 running as a daemon (not inetd) on
Solaris 8 configured to use a WINS server and provide authentication via
a PDC (same host as WINS server). I do have an lmhosts file in the
samba /lib directory with the PDC/WINS server address in it.
My globals section;
[global]
workgroup = WORKGROUP
netbios name = SAMBASERVER
security = SERVER
encrypt passwords = Yes
password server = pdc
lanman auth = No
log level = 2
log file = /usr/local/depot/samba-2.2.8/var/%m.log
deadtime = 5
keepalive = 600
max smbd processes = 5
socket options = IPTOS_LOWDELAY TCP_NODELAY
load printers = No
show add printer wizard = No
preferred master = No
local master = No
domain master = No
wins server = [IP address of WINS/PDC server]
follow symlinks = No
Samba works like a charm except that after awhile, samba goes "deaf"
(or
thats what I perceive to be happening). The user attempting to connect
to a share is prompted to authenticate. Repeatedly providing the
correct authinfo proves to be futile. When connections to samba fail,
nothing is written in samba's logs (currently set to level 3) and no
communication between the samba server and the PDC/WINS server is
observed. Sometimes bouncing smbd or nmbd works, sometimes it takes
many restarts. I've pretty much ruled out DNS/NIS at this point as
other services which rely on name resolution would have been complaining
by now ;-)
I've taken packet traces between winclient and sambaserver (fictitious
names ;-) of the failing and succeeding connections and they are
surprisingly quite disparate in content. I've included them here for
your inspection (my apologies for the length). (Unrelated packets have
been filtered out). Your comments/opinions are very welcome.
