[plug] no route to host(s), but can ping?

[Lucas van Staden]

Hi,

Just can't figure this out, and I am sure I am missing something obvious 
here.

Box is debian hardy 8.04

Can for example ping www.google.com:

PING www.l.google.com (66.249.89.104) 56(84) bytes of data.
64 bytes from jp-in-f104.google.com (66.249.89.104): icmp_seq=1 ttl=244 
time=276 ms

but cannot traceroute: (unknown host?)

--- www.l.google.com ping statistics ---
2 packets transmitted, 1 received, 50% packet loss, time 1004ms
rtt min/avg/max/mdev = 276.041/276.041/276.041/0.000 ms
web at webserver ~ $ sudo traceroute6 www.google.com
traceroute: unknown host www.google.com

Found that my smtp server stopped sending mail, with error 'no route to 
host'

Same issue, I can ping those, but I cannot traceroute.

I can access internet, downloads etc fine from the box.

Any Ideas what I am missing here? Or what to look at?

Seems like services cannot do DNS?

resolv.conf is set to my router as the dns server:

nameserver 172.168.0.1
