Message-ID: <20060324232128.GA23810@wonderland.linux.it> (raw)
After running this command from a remote host:
ping -M dont $MY_TUNNEL_IP -c 1 -s 1496
this was logged by the kernel:
Mar 25 00:13:13 wonderland kernel: mppe_decompress[1]: osize too small! (have: 1504 need: 1505)
and traffic over the tunnel stopped flowing. pppd logged this:
