[Dxspider-support] How to connect with PuTTY ?

[Bela Markus]

Hi Erik,

yes I have a firewall of course, but the funny thing is, that port 8000 
is enabled for the incoming TCP connections, while for outgoing any port 
is allowed. Additionally, SPIDER is running on the same machine as the 
firewall and the ADSL connection is. Anhow, this IS a fw issue for sure. 
Will spend some time for further investigation.

Regards... Béla
