I run an IPsec/Freeswan VPN to connect 4 disparet windows LANS.
I managed to RTFM until cross-subnet browsing worked (samba 2.0).
Having upgraded to 2.2.3 It would seem that this feature is not working.
BACKGROUND:
originally all sources of information led me to understand that I would
need a box running samba behind the firewall/IPsec box as I could not
even ping a remote internal IP from the firewall. I then built a few
cheap x86 boxes to simply collate share information then remote browse
sync to the DMB in the main office.
It worked!
Network neighborhood was never happier.
Since then my knowledge of iptables has increased and I now invoke
`/sbin/iptables -t nat -A POSTROUTING -o ipsec0 -s $EXTERNALIP
-j SNAT --to $INTERNALIP`
This allows me to connect to services on remote internal networks from
an IPsec Gateway.
AHA I thought. I can eliminate those
unsightly pentium samba boxes and place the share collation on the
reliable (and underworked) firewall/IPsec Gateways now that I could
actually ping the DMB from any given IPsec GW.
If I can ping the DMB from another samba server I should be able to perform
a remote browse sync without error.
CURRENT:
Since the only samba availible to the IPsec
gateway boxes was 2.2.3 I had to use it ( debian woody). I figured that
it would not cause any problems.
It would appear that something is foiling my attempts for the elegant
one box solution.
Unexplanibly the only box that correctly performs the remote browse sync
is one stray pentium running samba 2.0 (debian potato) which is on the
inside of the firewall. Perhaps because it always worked... hmm? I wonder.
The other two samba boxes luckily produce errors..

Hi,
I just read your samba problem and I belive I know
about 1% about IPSec, FreeSwan, Smaba, GWs, tcp/ip and
nothing about ipchains and friendss, but the ability
to ping a server accross the network is just a proff
of conectivity.
if you remember ping uses icmp packets and SMB uses
tcp (perhaps udp) packets they are very different from
a fw/gw prespective.
check for access to the netbios ports (you'll find
them in /etc/services) in your fw rules..
regards,
esv.

This samba server is alone in its subnet. It's host and netbios name
are TCSL. There is a NT4 WINS/PDC server on another subnet. Using
winbind, and authentication works (security=domain). Samba-2.2.7a-1. I
keep on getting:

I've tried two different WINS servers, and this samba server simply will
not show up in network neighborhood, etc. Any ideas?

umm you lost me...lets start again. remember, wins is for name resolution. What do you mean point to point connection? ie Ras or vpn ? whatever you dial into has to include you in their browse list or your samba box has to be a local browse master and sync browse lists with the pdc after a wins lookup. It is a domain member right? If i've erred I hope someone will correct me. regards, Richard Coates.

I was also under the impression that wins allowed a server on a different subnet to show up in network-neighborhood, by syncing browse lists with the domain master browser (in this case, an nt wins server and pdc). By point to point I mean a network where there are two ends, A and B. B is in its own subnet, no broadcast, it uses A as its gateway/router. There is nothing else in that subnet. B access the network through A. The samba server is B. B is a local master, but not a domain master. The samba server is a domain member, with winbind and security = domain, and that part is working. The part that isn't working is: nmbd[19140]: [2003/03/03 06:44:18, 0] nmbd/nmbd_browsesync.c:domain_master_node_status_fail(262) nmbd[19140]: domain_master_node_status_fail: nmbd[19140]: Doing a node status request to the domain master browser nmbd[19140]: for workgroup [my_domain] at IP [ip addr of nt pdc/wins] failed. nmbd[19140]: Cannot sync browser lists. The domain name and ip address are correct, and an nmap -P0 -sU -p 137-139 (ip_addr) shows: Port State Service 137/udp open netbios-ns 138/udp open netbios-dgm 139/udp open netbios-ssn But samba won't sync browse lists. ~ Daniel ----------------------------------------------------------------------- This message is the property of Time Inc. or its affiliates.

If I understand this correctly wins provides the address of the pdc so the local-subnet-master-browsers can sync their browse-lists with it.> By point to point I mean a network where there are two ends, A and B.

We used a samba box to share a dialup a couple of years back with similar unreliable browse-lists. From memory if samba was restarted AFTER the ppp interface came up it worked quicker. hope this helps, Richard Coates

The interface is defined in smb.conf. Smbd/nmbd is started after the network, so that shouldn't be the problem, and restarting it does not help. ~ Daniel ----------------------------------------------------------------------- This message is the property of Time Inc. or its affiliates.

No the tcpdump makes no sense to me either!! just curious what os uses interface ctc0 ? well your ping packets are returned so routing should be ok.. samba is configured to use/listen-on interface ctc0 right ? what does smbclient -L winshostname -U validuseronserver return? if i'm right an error, as the "winshostname" won't be resolved. And probably no other names either except by "broadcasting" on local lan when wins-retries time out. Ahh wait a minute...if some things work and not others...I believe wins calls are udp protocol based NOT tcp...even though the port nos are the same. which brings us back to the firewall again!!!! regards Richard Coates.

Well, thanks for all your help.> interface ctc0 ?Channel to channel, a point-to-point connection without broadcast, one of the interface types that are available with the s/390 architecture. That could be why the tcpdump looked screwy. The server is dual-homed, I'll go ahead and add the eth interface to samba, route to the pdc through that, and see if I have better luck. It'll at least help in diagnosing with tcpdump, probably.> what does smbclient -L winshostname -U validuseronserverI saw the shares on that WINS/PDC and below that, the computers that show up in network neighborhood (and mine wasn't in there :(). Things just got more interesting... I changed the route table so traffic to the pdc goes through the eth0 interface, and added eth0 to my interfaces line in smb.conf. Right after firing up nmbd I got: [2003/03/10 07:10:46, 0] nmbd/nmbd_responserecordsdb.c:find_response_record(235) find_response_record: response packet id 693 received with no matching record. [2003/03/10 07:10:46, 0] nmbd/nmbd_responserecordsdb.c:find_response_record(235) find_response_record: response packet id 694 received with no matching record. but since first start, it hasn't shown up in log.nmdb, and now the wins server sees me, the samba server shows up in network neighborhood. I've read that the find_response_record sometimes occurs with subnets with some versions of win95 on them? I don't know what's on that subnet.> Ahh wait a minute...if some things work and not others...I > believe wins > calls are udp protocol based NOT tcp...even though the port > nos are the > same. which brings us back to the firewall again!!!!Well, using either interface, nmap -sU -p 137 [wins/pdc] says: Note: Host seems down. If it is really up, but blocking our ping probes, try -P0 And using -P0 works over both interfaces, shows 137 udp open. Same deal with tcp 139. Have to -P0 and then it shows it open. Unfortunately users are on now... tomorrow morning I'll try switching back to ctc0 and see if things stop working. Things stopped working the first time over a weekend, and the windows guys said that the pdc/wins server had crashed and burned and needed to be rebooted, and since then I wouldn't show up anymore. Wishful thinking, I know, but maybe connecting over the other interface will get me back "in" over the interface which used to work and which I should be connecting over, ctc. I guess I'll find out tomorrow. I took a tcpdump over eth0, a lot more chatty (probably because things are working, and it may just be a chattier interface). Any things I should be looking for in it?> regards > Richard Coates.Thanks for your patience, ~ Daniel ----------------------------------------------------------------------- This message is the property of Time Inc. or its affiliates.
