Thread: Internet Port 139
January 11th, 2003, 11:41 AM #1
Internet Port 139
I went over to "sheilds up" and ran there test.
It indicated that it could not find port 139, could not receive any response from so and so.
Could not blah blah access my netbios.
Only thing is I had Zone Alarm Pro completely shut down.
So what's the deal?
Is XP more secure then is known or is this something thru AT&T Broadband?
Or is this test crap?
Oh, what is port 139?

Test is a bit poor, actually, I should have linked a better one.
Port 139 is NETBIOS , where you can find stuff about your PC and OS, and get in if you have a mind to.
XP's firewall will block access to Port 139 I think, so if it's on that's why.
Try Sygate's scan for another try. It's still simple, but better. And Symantec has a series of scans which are reasonably thorough.

XP has it's own firewall?
That's news to me.
Where do I find it at?

right click on my network neighborhod> click propertise> right click on the local connection you have setup> click the advance tab and there is the firewall settings. its off by default

I never went in and looked at this.
I completely forgot about these settings.
I've always disabled "file and printer" sharing on my "internet" computer.
Somehow I completely forgot to do that when I put this computer in service a year ago.
The XP firewall was not enabled. Since i'm running Zone Alarm Pro I suppose this should remain disabled?

eh i rather put faith into za than ms firewall. i believe turning on the xp firewall is jut gonna cause more problems down the road with file sharing or something else. update your win xp box and keep up with za updates and you should be pretty good to go

Thanks (again) GZ3
Is it still the practice to uncheck file and printer sharing though?

im behind a linksys router and i have file and printer sharing on the computers that i access alot. any machine i do not share files with a keep the option off. i feel pretty safe being behind the router. i update often. try to keep a watch out on who coming in wallwatcher. to be honest i really don't get alot of hits on my router. only when people are getting on my ftp.

GZ3, I have to take some time to organize my Favorites.
I added the link. That looks to be a nice add-on.

That WallWatcher log viewer looks interesting.. scrnshots sure looks like it beats the Linksys logger Thanks, Jason.

Cool! thanks, kenyg
I've never gotten around to getting a specific logger setup for it.. tsk, tsk, shame on me

Odds are AT&T blocked it. Some ISPs do this.

Oh, thats a good thing, rigghhtt?

Does woodbutcher have a router? If so, the router probably stopped the access to port 139 on the WAN side. When I go to the Shields UP! site, it can only check my router because of the private domain IP address my two computers have, and the router won't let anything through except what I request. That's just from my experience though. If you have set the computer to DMZ or ket ports go through without SPI then it wouldn't have been blocked.
Just my 2 cents...
BTW, doesn't anyone have a router besides Linksys?
January 12th, 2003, 12:14 AM #16
I have a router, yeah it's a sony, I mean linksys.
Not in use yet. Right now straight out of my sb4100 motorola into the built in nick on my K7S5A.
I was looking to see if the modem had some type of a firewall (thought I had heard something to that affect).
I couldn't find anything.

I've got a D-link router/gateway thing between my cable modem and switch.
Yes, it's good that 139 isn't accessible from outside. If it was, people not on your local network could browse your file shares.

I don't think the Motorola Surfbaord modems have a firewall at all. I have SB4100 and there is nothing about a firewall on the website. Doesn't support NAT, so I doubt it very much.

Have you tried the other tests?
I don't know of any modem that has a built-in firewall... But there's always something new out there...
If you truly have all firewalls disabled, then it must be your ISP blocking that port...
My DSL ISP lets all traffic back and forth, so while it's good if you want unrestricted internet access, you've got to be careful how you set your router up.
But, I had the local "h4x0r" club try to crack into my server box, and after about two months, they still haven't been able to touch the thing...
