Solved Unable to ping out, or netstat, etc

[zipitup]

Hi guys, I suddenly noticed that there is an issue with my box. I haven't done much with it - not sure if it was attacked but it doesn't seem like so.

I was trying to investigate why w(1) takes 2 to 3 seconds to show completely. Then I thought maybe it is trying to resolve my IP address. When I check resolv.conf, it is still pointed to 8.8.8.8 and 8.8.4.4.

So I checked /var/log/messages, and also saw this (yes I use no-ip):

Jan 31 09:20:55 nb1 noip2[562]: Can't gethostbyname for dynupdate.no-ip.com
Jan 31 09:20:55 nb1 noip2[562]: Can't get our visible IP address from ip1.dynupdate.no-ip.com

And then a simple ping to www.google.com won't work. And then ping to 8.8.8.8 also doesn't work. After a while SSH would disconnect me, even if I VPN into my box, then VPN would also break. Sounds like the kernel is breaking the TCP pipe.

I wanted to check the route and I also get this:

root@nb1:~ [CMD]# netstat -r[/CMD]
Routing tables
Internet:
Destination        Gateway            Flags      Netif Expire
default            gw                 UGS         re0
packet_write_wait: Connection to 113.xxx.xxx.xx: Broken pipe

And I'm out of the server again.

Hmm.. any idea what else should I be checking for?

Thanks..
