You've got hacked :)

Yup since I opened up the ssh ports, once a day someone tries to get into the system. Here a small piece of log,

The address belongs to some kid in China (Beijing Education Information Network). The box has been safe so far.

Nobel Gases

Finally after successfully setting up OpenVPN with Linux server and XP/Ubuntu clients (Vista is evil), we decided to create the final network, but were stalled with the general problem of names (wonder what will I do when I have to name my kids!!). Looked around for tips and there is an RFC on it RFC 1178 which gives a few tips for names.

Without much ado the names helium, neon, argon, krypton clicked. Nobel Gases I say...
