Never think your password is complicated enough

Last week I was asked to help a friend to check out his server that has been hacked. First I was thinking some kind of PHP leak or SQL injection. But I was wrong. The crack uses some kind of SSH user/password scanner and got his root password.
I find this out because the cracker created […]

File based virtual user settings for Vsftpd on FreeBSD

I’ve done this before with the help of a very good blog entry. But when I tried to do the same thing today I can’t find that page. So I decide to write this down, in case I’ll need it later.

Copy file in the order of their name

Last weekend I got myself a small MP3 player called Q12.
I really like this small one cause I can carry it everywhere and save me some time while I’m walking or waiting.

Why the FreeBSD ports system rocks

Well I need to handle some PHP upgrade on a Debian server some days ago, and it turns out to be a nightmire…
