When I try to ping an external address I always get the same error: "Destination Port Unreachable", and when pinging domain names I get an "unknown host" message.
I have Tails 1.6 and run tor when connected to the internet, also i'm using terminal to ping.
What could it be?
The ping tool uses ICMP packets, which are not supported by Tor, and therefore can't be sent from within Tails. (Tor supports only TCP as its transport layer protocol.)
For TCP-based alternatives, you could take a look at this thread. Note that to install any additional software on Tails, you'd first need to ensure that an admin account has been created.
