Samba - microsoft-ds connection?

2005-01-22 Thread Marty Landman
Hi,
Sorry if the subject's a bit cryptic. It's because of my ignorance, here's 
what I do know. Have just installed FBSD 4.8 release from the mini-iso, my 
old install got messed up and got Samba 3.0.10 running.

My win xp workstation is also my current gateway. Run a tcp monitor on that 
box called tcpview which displays active connections. Here's what I see for 
windows networking

System:4TCP delliver:4885   swamisalami:microsoft-ds 
ESTABLISHED
System:4TCP delliver:3031   penguin:netbios-ssn ESTABLISHED 

System:4TCP delliver:4852   eileen:netbios-ssn  ESTABLISHED 

Swamisalami is my fbsd, penguin's my rh9 box running samba 2.x, eileen is a 
win me workstation. Delliver is my gateway box.

What is microsoft-ds? Couldn't find anything about it in MS' knowledgebase.
Marty
p.s. yes I plan on moving my gateway to fbsd, but it's going to take some 
time for me to get there

A good short description of the ms-ds protocol is given here:

Hello,

It MS's Directory Service, what is usually called SMB. As long as it's
between systems on your network, it's nothing to worry about.

HTH,

Ahah, then maybe there is something to worry about. I'm quite sure my 
system's been hijacked in the recent past. And I've seen the ms-ds port 
being opened on a steady basis for outside connections. Guess if I used 
fbsd as my gateway then could close it up with ipfw, but for now I just 
unplug my dialup at night and close nasty looking connections by hand when 
I notice them.

Hello,

Yes, this is a well-known attack vector in the Windows world.
Regardless of a gateway's OS, one should be running as good as possible
firewall checking all incoming and outgoing packets. Windows machines
in particular are targets and should be running anti-virus, spyware,
and firewall software locally, as well, to add another layer of
protection.

Regards,

stheg

Once that happens the system is shot, the attackers bury so many back
doors
in the system that you will never find them all.

Microsoft has a number of documents on how to secure their stuff on
their website.
