The network that the client is running on has an outbound firewall that prevents the client from connecting to the server. Is there any way/workaround to create a TCP connection through this firewall? I have tried to use common ports that are open such as ...
Hello, I am trying to add trusted sites to Mac OS X's firewall via command-line. I understand that previously, we were able to use ipfw to configure the firewall on a packet level by using port numbers or IPs. In Leopard (10.5) and on, there is a new feature to add a trusted application to a list. This can be accomplished using the U...

I was reading the nmap source code because I'd like to find out how does it discover that certain ports are filtered or firewalled. I have some experience with sockets in c and i've built simple port scanners, that's easy - if the connection succeeds, the port is open, otherwise it's closed (because of the RST returned). But in case with...
Right now I'm distributing a .app file to people in my organization. I drag it to /Applications by authenticating as root, but every time the users launch the program they get a firewall warning.
