samba - Dec 2000 - "Finding" a samba server

Hi

I am at university and I have a FreeBSD machine on the accomodation network.
It acts as a NATD router to a couple of other machines i have in my room. It
is running samba 2.0.7 and can communicate with the windows machines on my
LAN via network neighbourhood.

For the machines in public access labs on campus there is a what I have been
told is a samba server which serves each user with a place to store files
(which is maped at login).

I wish to use smbmount on my freebsd machine to mount this directory,
however there is a firewall between the accomodation network and the rest of
the campus which blocks TCP 139.

I have read in a number of places that I can use SSH to forward the local
port on my machine of 139 to a unix machine on the campus network, which in
turn will contact the samba server for the campus network.

My problem is that I don't know the address of this samba server. Any ideas
how to find it? (other than contacting the sysops which would looks well
dodgy :-)

Thanks

Steven

smbmount is for smbfs and smbfs is linux only. Sharity (light?) may be an
option.

Correct, if you have ssh access through the firewall you can tunnel
"anything" through that. Given that the ssh server on the inside
allows
port forwarding.

Of course, you don't have to use 139 on your local machine,
smbmount/smbclient will let you connect to any portnumber.

If you suspect that the sysadmins would object then maybe you should ask
them anyway before doing this.

nmblookup can find IP#/netbios names for you. If the unix box on the
campus network doesn't have samba already just compile it.

Note that ssh port forwarding by default only allows localhost to access
the forwarded ports. This can be changed (-g) to allow remote hosts to
access. However, do think before you enable that since it will allow
anyone that can reach your machine to reach the inside of the fw. Proper
firewalling rules on the freebsd box should prevent that.
