Seems to be a very common thing of late, you can directly test if you at risk with this by clicking
here  (port 135 on your comp will be probed)

This link will instantly and easily test anyone's Internet-connected PC. "Open" is BAD, "Closed" or "Stealth" is safe.
 
Lots of other security tests can be performed at the main Shields Up page which we all had fun time? on IRC doing last night :-)
Seems to me that test isn't very reliable.
I probed my ports several times without changing any firewall settings, and still I got different results on some ports (some times closed, some times stealthed), but at least they didn't appear to be open  :-)

as long as you two don't start probing backdoors...

Gibson (of GRC) is sort of a benign loon; he does his best to help the little guy, but there's the bit of the showman to him, and his technical knowledge itself is really only.. middling to average.  Off the top of my head, DSLReports offer some similar tests with more detail and less obfuscation, or you can find a copy of 'nmap' or another portscanner and conduct them yourself (though you'll probably want a remote machine to test from).

Basically, 'closed' would indicate the port returned a TCP reset or reset/ACK pair.  'Stealth,' from Gibson's perspective, seems to indicate the port didn't respond at all - well and good - but you can get the same impression if the packets are lost on their way for whatever reason.  If you're stuck using people's web-based tools, it's good to get a second or third opinion.

Basics of TCP negotiation and 'theories' of portscanning here, or a million other places via Google.  nmap itself is over here, and there's even a Windows version available.

Agreed, if he had just kept to the point and not tried to over-dramatise everything, he'd probably have a v. good reputation today in techie circles.

And firewalls are not the be-all and end-all of human existence, nor will they fend off all attacks, or even the majority of attacks aimed at Windows machines.

The only time anyone should give a stuff about a port closed response and no response at all is on a high-profile publicly accessible facility (such as a well-known website), where more time is taken responding to all packets than letting a firewall do it for you.

There is no substitute for a well-configured machine, except for the power cable being pulled out :-)

@Calen

I don't think "fun" is the word I'd use :-P

@Elektro

Probing backdoors eh?  We'll just leave you to do that :-D

Real credit goes to whoever on the TenDRA (C-and-other compiler, formerly of the UK DERA, now under an unrestrictive license*) team cooked it up and released it.

More over here, of course the DragonFly project is over there...

Your system has achieved a perfect "TruStealth" rating. Not a single packet — solicited or otherwise — was received from your system as a result of our security probing tests. Your system ignored and refused to reply to repeated Pings (ICMP Echo Requests). From the standpoint of the passing probes of any hacker, this machine does not exist on the Internet. Some questionable personal security systems expose their users by attempting to "counter-probe the prober", thus revealing themselves. But your system wisely remained silent in every way. Very nice.

You need to switch your machine on first.

this MsBlaster got me too but cos I'm running Win2k showed itself as svchost.exe crashing and disabling some functioning of the PC. Also wouldn't reliably connect to webpages. Ran Mcafee Stinger from this !link and installed the MS security patch - now all is fine.
IT really took me by surprise as all I did was connect briefly to the internet to get it - but then I am running no virusguard or firewall...will be in the future :)

I've sorted the problem on my cousin's XP box.  I stopped the MSBlast task in Task Manager, used MSConfig to stop it at startup, the used the FixBlast (or whatever it was called) to get rid of it.  Then after a reboot and checked it was gone I installed XP SP1  and installed Sygate Personal Firewall and set it up to block port 135.

All is done, all is good :-D

.....

until the next time :-x

Cheers for the help :-)

Did you check ports 3330-3332 and 3362?
