Go to “firewall->advanced->network security policy”.
There is no perl.exe in the list of applications.
Close this window.
Launch “perl.exe test_tcpip.pl”.
Go to “firewall->advanced->network security policy” again and see perl.exe in the list of applications with rule “allow any->any”.
Why rules are added automatically with no notifications?
My configuration: Vista x64 SP1 + Comodo Personal Firewall v3.5.57173.439 64bit (Firewall Security Level=Safe, Defence+ Security Level=Safe)
ps: if new vista+comodo+perl is installed, this problem disappears and comodo always shows alert if perl.exe tries to send a tcpip packet. This bug is with my old vista. Probably there is something to do with comodo settings?
