Comment 6 for bug 1549467

Hi, Alkis, you're welcome!

Thank you for the fixes! Amount of ram is now detected correctly.

But still info() fails on that router-client. According to routing table 'server' is accessible through interface tun0. But tun interfaces do not have MAC address, therefore info() fails with "ERROR: Empty MAC". Please check the output:
ip link show dev tun0
6: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN mode DEFAULT group default qlen 100
    link/none

maybe we should use
MAC=`ip a|awk '/ether/{print $2;exit}'`
as a fallback? Anyway, client is uniquely identified with any of the MACs it has.
