My ADSL connection is protected by iptables. It allows all packets out (which is bad, I should really fix this) and it will accept packets back in that are related to existing connections. It drops any other packets. You can find it here: segfault.slackware.co.nz

Chill - talk to me on Jabber and I'll do an nmap scan of your machine to see whats open.

190798 2003-11-12 05:49:00 Sorry dude, my Jabber is bust and I cant work out why :-(

Try another IM-Protocol perhaps ;-)

I too have iptables running, but its on the machine with the proxy.
I've only got 3 ports open now on my Router (Was 4, but I closed 3210 which I was using for my Proxy):
SSH
FTP
HTTP

Aside from that, its all locked.

190799 2003-11-12 06:00:00 Well it wasn't me :D I only grabbed acouple of text files when I was talking to you. PoWa (203)
190800 2003-11-12 06:03:00 Errr... Would you mind emailing me otherwise, Chilling_Silence[at]orcon[dot]net[dot]nz

I would post my IP on here if you wanted to portscan me.... but that's prolly not a good idea.

ive nmap'd myself and it shows telnet and a few others open (on the router) which is probably right. 4 ports, the rest are closed.

190801 2003-11-12 06:05:00 Hehe.. And I had about 6 random IP's connect to me after that... Dunno who they belong to but they didnt download anything :p Chilling_Silently (228)

I think I was one of the 6 that tried you to see if it was block :D

This might be able to help go to www.grc.com then do a ShieldsUP!( here is a direct link to the test: grc.com ) then you should see what is open & close

Hope this helps :)

190804 2003-11-12 08:43:00 If you want to avoid attention you could move SSH, FTP & HTTP to non-standard ports. This is what smoothwall does, where HTTP is port 81, and SSH is 222. It means you won't show up on the general port scans. bmason (508)
190805 2003-11-12 08:54:00 First off; Dont get online unless you are able to master your machines, your connections and ports. People like you, hosting a proxy, making it possible for spammers to use oughta be banned from the net, Sorry!

And yes, DO contact the ISPs used , logs you already got. Happy hunting, even tho I doubt anyone will do **** about this...sigh..

190806 2003-11-12 08:54:00 So you mean like doing that through my Router...
Have it taking ports 81 for example and mapping them to port 80 on my PC?!

I s'pose so.... Could be interesting training my friend to conntect to my FTp on port whatever.. I s'pose I just throw that on the end of the URL I send them though.. :-)

Thanks for the advice, Will do :-)
