  • You may go to Internet by means of your home ssh server. You must configure your local proxy to send traffic through the proxy. Many programs allows that: firefox, pidgin, skype, gnome, etc. Your home ssh server must listen in any of the ports permitted by your enterprise firewall. That usually includes 80 and 443.

    autossh -N -D localhost:1080 myhome.example.net -p 443

  • If you are an unlucky soul behind a corporate firewall you will likely find that downloading gpg keys is blocked. This is because the hkp protocol uses port 11371 by default to transfer the key. By adding "hkp://" to the beginning of the hostname and ":80" to the end you are asking gpg to try using port 80 to connect (less likely to be blocked by a firewall). This relies on the remote server answering to requests over port 80. Show Sample Output

    sudo apt-key adv --keyserver hkp://keys.gnupg.net:80 --recv-keys [key to get here]

  • this command will send a message to the socket 25 on host 192.168.1.2 in tcp. works on udp and icmp understand only IP address, not hostname. on the other side (192.168.1.2), you can listen to this socket and test if you receive the message. easy to diagnose a firewall problem or not.


    23
    echo "foo" > /dev/tcp/192.168.1.2/25
