[newbie] Port scanning

[Jo�o Candido Araujo Milasch Filho]

Hello, (I'll resend this message, cause I think it have not been sent b4)   I'm trying to use some services that i'm setting up at my computer at home, but the firewall here, where i work, blocks almost all the outgoing ports, so, i cant connect to my home computer. So, despite the network administer dont want to tell me which outgoing ports are unblocked, i want to discover it, by scan, or by any other way. But the scan services we find on the internet always scan incoming ports.   Can anyone give me a light on how use that?   BTW, anyone know how where to find a step-by-step guide on configuring ssh? I'm a newbie, so, i didnt figure out how to configure it.   thanx all!!!
