SSH Access in 10.0

Question has no doubt been asked before but I need to be able to use putty.exe to access my SuSE 10.0 (Retail) box. I've tried both v1 and v2 protocols. I can putty.exe into another Linux box on my network and then ssh from that box to the the SuSE 10.0 box so I know it is accessible with my user credentials using ssh externally. Attempting to use access the 10.0 box directly, using putty.exe, if I use v1 (default), I get the login prompt okay but I can't authenticate with my password. If I use v2, putty.exe crashes badly... End of story at that point. TIA Clint
