 +Access via ssh not possible, MTU value to high!
 +
 +In some cases the MTU value is too high, which results in an very strange
 +situation: ping works, but ssh hangs at this point:

 +...

 +and a possible solution/workaround for Linux Mint:

 +
 +Check the current MTU value:
 +
 +  ip link | grep mtu
 +
 +Set MTU value on interface eth0 to 1392
 +
 +  /sbin/ifconfig eth0 mtu 1392
