I removed firewall from my computer but I still get "Permission denied" 
message. I'm not really an expert on firewalls so can you tell me some 
things :
Does firewall works with both sides i.e. will firewall block me from 
sending something from inside of remote host to my localhost ?
If that's the case how do I lookup for open ports on that remote host 
through which I can send data ?
