Hi guys,
First of all, thanks for your great work. So many people *need* Samba to
work...!
I have a couple of questions about Samba. I have been fiddeling with Samba
config files for some time now (as well as reading documentation about
it), and... there must be something I am missing.
The network I am managing has a very, very standard configuration.
It's a C class (netmask: 255.255.255.0), let's call it x.y,z,w.
There is a PDC, PHOENIX, with IP x.y.z.155.
Now, I have two different scenarios.
1) BEFORE RUNNING SAMBA
-----------------------
I run:
[root@cooee /root]# findsmb
IP ADDR NETBIOS NAME WORKGROUP/OS/VERSION
---------------------------------------------------------------------

[root@cooee /root]#
Ant that's brilliant. I understand that the "findsmb" script only
runs the
commands:
nmblookup -r -A $IP
smbclient -N -L <NAME> -I <IP ADDRESS> -U%
So, if I run:
[root@cooee /root]# nmblookup -r -A 203.25.173.157
Looking up status of 203.25.173.157
received 5 names
NORMAN <00> - M <ACTIVE>
HADES <00> - <GROUP> M <ACTIVE>
NORMAN <03> - M <ACTIVE>
NORMAN <20> - M <ACTIVE>
HADES <1e> - <GROUP> M <ACTIVE>
num_good_sends=0 num_good_receives=0
[root@cooee /root]#
Everything seems perfectly fine.
[root@cooee /root]# smbclient -N -L NORMAN -I 203.25.173.157 -U%
added interface ip=203.25.173.1 bcast=203.25.173.255 nmask=255.255.255.0

Again, everything seems to be OK.
2) AFTER RUNNING SAMBA
-----------------------
Well, at this point, the problems start.
The program "findsmb" takes ages to run, and the result is
(surprisingly)
dirrerent:
[root@cooee /root]# findsmb
IP ADDR NETBIOS NAME WORKGROUP/OS/VERSION
---------------------------------------------------------------------

[root@cooee /root]#
It's very odd: Why is the looked up hostname there, instead of the NETBIOS
names?
Now, this is what happens when I try to run *exactly* the same commands I
mentioned earlier (that are, what "findsmb" runs to look up
information):
[root@cooee /root]# nmblookup -r -A 203.25.173.157
Looking up status of 203.25.173.157
No status response (this is not unusual)
[root@cooee /root]#
...and:
[root@cooee /root]# smbclient -N -L NORMAN -I 203.25.173.157 -U%
added interface ip=203.25.173.1 bcast=203.25.173.255 nmask=255.255.255.0
Domain=[HADES] OS=[Windows NT 4.0] Server=[NT LAN Manager 4.0]

The second command looks fine, but... so, it is the lookup that is
behaving a bit funny (well... is it?).
CONCLUSIONS
-----------
Here are my questions:
1)
I think this lookup problem (if there is a problem) might be releated to
the fact that when a client clicks on "cooee" in the "Network
Neighborhood", it takes at least five seconds to have a directory listing
coming up. Is that correct? If not, do you have any ideas about what is
causing the delay to happen?
2)
Can you see any major problem is the configuration attached below? (I
stripped all the "#" comments...) My knowledge of SMB is quite narrow
(I
only read the documents in the "texd_doc" directory, and...)
I apologise if this email is rather pathetic from a technical point of
view, and I would strongly appreciate any help.
THANKS!
