Finally, ssh server and ftp server is also back. Well, I have to claim it first. I never set both server for 5 hours. Actually, I was out for about 4 hours. Therefore, I only set it for almost 45 minutes.

Well...keep going...

I am thinking whether I should apply a dynamic DNS service or just set BIND myself. I only know setting DNS for BIND behind router with dynamic ip address was never a easy routine...

Well...the decision seemed that it was surfaced itself...
