 |
|
Hi all,
Everything was working fine and my gentoo system was running perfectly (well almost:)). Untill I gave the command emerge system after downloading the latest portage (07.09.2003). And now I have problems using net. For some hosts on our network it is working perfectly. But for others it is behaving erraticaly. For example for our primary dns server the output of pinging is:
| Code: |
PING 172.31.1.1 (172.31.1.1) 56(84) bytes of data.
--- 172.31.1.1 ping statistics ---
50 packets transmitted, 9 received, 82% packet loss, time 49000ms
rtt min/avg/max/mdev = 0.380/1411.906/5233.350/2050.568 ms, pipe 6
|
As a result internet is very slow. Everybody else seems to be doing fine, however. Please help me.
A few relevent outputs (or which seemed to me to be relevent) are given below. Ask for more if you need any.
