SSH Login from a PC

Calling all SUPERGEEKS! Help with SSH Login from a PC

Hi guys,
I'm attempting to access my Mac from a friends PC using SSH.
I've downloaded and installed Putty on the PC, then entered my Mac's address as:
ssh my name@my ip address
and\or
my name@my ip address (without the 'ssh')

I get a fairly quick Network Error: Connection timed out.

My Mac back home is configured with automatic DHCP, and I use DyNS to assign a permanent IP address online, which I'm pretty sure is different from the one my Mac has offered me in System Prefs. Could that be the problem? I haven't turned the Mac off since it offered me an IP address to connect to through SSH.

Just to update this v. old thread. I've since discovered that I need to set a finger print on both my mac and the pc I wish to use to connect to my mac. I found this great site that goes through it all. I haven't yet tested it out but will post back as soon as i do.

Thanks for returning with an update.
