A firewall is blocking the local communication chanel (socket)... Error on Windows 7

[GoogleCodeExporter]

I am using Winpdb on Windows 7 Enterprise with Python 2.7.2 installed on it.

I have installed winpdb 1.4.8

I am trying to debug an embedded Python code in my application, but whenever I 
try to attach I get the following error:

“A firewall is blocking the local communication chanel (socket) that is 
required between the debugger and the debugged script. Please make sure that 
the firewall allows that communication.”

On my colleagues' machine which has Windows XP it is working fine.

I tried to disable the firewall completely but it is still not working.

Does anyone have a suggestion what is wrong here?

Thanks!

Same issue on Fedora 16 with Python 2.7.3 and winpdb 1.4.8.  The firewall has 
port 50001 open to all incoming and all outgoing connections are allowed:

Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination

Looks like same issue on Ubuntu 13.10 WinPDB 1.4.8 (installed via apt-get):
> launch simple.py
*** Failed to find script.
*** A firewall is blocking the local communication chanel (socket) that is
*** required between the debugger and the debugged script. Please make sure

$ sudo ufw status
