No need to get angry. The addy's you mentioned will not change no matter what the IP might be. We all have those name based addy's plainly because we use Telkom as our service provider. Thus even an IP change won't affect it. []
If that addy is scanning the Telkom ADSL userbase, we should be able to pick it up soon. Anybody who can, please check your logs. Lets see if we can figure out what is going on here. Lets not accuse people of cracking or hacking before we have proof. The most logical explanation is a virus... But let us check it out anyway...
All you Linux and Windows sys admins, lets see what we can come up with...
