I'm running Ubuntu Intrepid.
Shields Up shows port 22 as open and vulnerable. I have Firestarter ICMP Filtering set for NO response to echo requests (no ping or pong), but port 22 responds to Shields Up pings anyway. Is there a way to stealth port 22? I can figure out Firestarter better than other Linux Firewall guis, but it won't do what I want it to. I tried gufw and couldn't figure out how to manage it.
well IS port 22 open? That's ssh if you're not aware. and an echo request IS ping (icmp type echo request) and won't relate to tcp sockets.
Yes, I did know that port 22 is ssh and it is the only port that Sheilds Up sees because it answers the ping even though Firestarter is set not to respond to any pings. LS ping gets me a cute little choo choo train that goes across and disappears without telling me anything in the terminal.
a tcp port can not respond to a ping, it's a different protocol. There are things which may been seen to perform a similar function, e.g. attempting for a tcp half open, but not a ping. Can you clarify exactly what is happening and whether we are trying to address a tcp or icmp problem.
again though, IS ssh open?? If you're not sure, run "iptables -L -n -v" and show us the actual config firestarter has provided for you.
Well there's no default deny, so unless i'm missing something all tcp connections coming in will be permitted outside of any rules there. so... IS SSH RUNNING? DOES SSH WORK?
Again, you can not "ping" port 22, we need to stop using incorrect language.
OK, here's the deal; you are posting to a 71 year old lady who discovered computers about 6 years ago and Linux about a year after that, so not only do I not always understand the answers that I get to my inquiries, I don't even understand the questions sometimes, but I am having a lot of fun just the same. I would never make it without all of the very helpful people on forums and the linux articles on the net. I don't know enough to use correct linux language but I learn more all the time. I would assume that I'm running ssh because it is installed and Sheilds Up 'sees' port 22 (is that correct?). All I know about ssh is that it seems to have something to do with passwords. ....I can hear you groaning from here : ).
OK, well what is your internet architecture you're running there? This laptop is directly connected to the net? Not behind an adsl router or anything? Whilst to be honest I'm a little grey as to how iptables is meant to be handling new tcp connections in general, if you don't want to use ssh, just turn off the service.

This is a PC connected to a broadband cable that runs through a router that also has a wireless function. I don't know whether or not I want to use ssh because I don't understand exactly what it does, nor do I know how to turn it off. I think that I am in so far over my head that I should probably just leave things as they are and hope for the best!
Turn off SSH.... System, Administration, Services, unlock, untick Remote Shell Services. SSH is a way to log into the box and get a terminal on it from a remote machine. Like remote desktop on windows, but command line only.
