Ideas: perhaps you could display network and broadcast addresses, though I'm not sure how useful it would be since most people who would need it could calculate it anyway.

N00b question: what is the ppp0 interface used for? IPsec? I know what the ppp stands for, but if some1 could give me a few examples for use would be appriciated.

@Reflektorfalke: can I ask you which version you had previously installed and also wether you use any script to move-symlink files from /opt ?
Which version are you using now?
Which version are u using now?
Did you try reverting to the older version?

"Yes, had older version an it worked until recently." Does this mean it stopped working before you updated?
