 Posted: Thu Sep 20, 2007 6:02 pm Post subject: Network has stopped working[solved] |
 |
|
I haven't updated my system since last Friday and have been using my network every day since then. I started my computer up tonight and the network connections do not work. I followed my usual pattern of starting Firefox and e-mail and neither would connect. I then tried ping and that can't find anything either. The only odd thing I can find in dmesg is:
| Quote: | ADDRCONF(NETDEV_UP): eth0: link is not ready
eth0: network connection up using port A
speed: 100
autonegotiation: yes
duplex mode: full
flowctrl: symmetric
irq moderation: disabled
scatter-gather: disabled
tx-checksum: disabled
rx-checksum: disabled
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready |
I have not noticed this before but then I don't look much. The only thing I think that I have done over the last day or two is add the screen grabber addon to firefox. There is nothing wrong with the hardware as I am currently in Africa on the same machine and posting to this board from it. If any more info is needed please ask. By the way Opera also cannot connect when booted in Gentoo.

I have just remembered that I installed PEAR-PEAR the day before this happened could this have anything to do with it.

How can you post to the internet if your internet connection doesn't work?
Do these commands and post the output:
ifconfig -a
ps aux|grep dhcp
ethtool eth0

I can post to the Internet as I have booted into my Ubuntu partition on the same machine. That is how I know the hardware is working it is what I meant when I said "in Africa". Sorry to confuse. Anyway the output you asked for:
ifconfig -a
| Code: |
eth0 Link encap:Ethernet HWaddr 00:0E:A6:C6:5F:BE
inet addr:192.168.1.5 Bcast:192.168.1.255 Mask:255.255.255.0

RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) |
I know the sit0 line wasn't there even yesterday when this problem started. It is not there if I run the same command on the Ubuntu install either.
ps aux | grep dhcp
| Code: | root 4484 0.0 0.0 2676 244 ? Ss 19:21 0:00 /sbin/dhcpcd -h osiris -R -N -Y eth0
root 5215 0.0 0.0 2776 556 pts/0 R+ 19:23 0:00 grep --colour=auto dhcp |
Can't run ethtool as it is not installed and I can't emerge it as I can't connect to the Internet from Gentoo. I also checked and I had not installed PEAR-PEAR as I had earlier thought.
Thanks for any input.

Excellent tip thanks I have actually chrooted into my Gentoo from Ubuntu now so that I can try to fix it from here without constantly rebooting. Actually this is why I keep this install around.
ethtool eth0

I also tried emerge --sync from the chrooted partition but still get temporary name resolution errors or timed out messages but can still browse the web happily from outside Gentoo. thanks for any help.

I have tried using ping and these were the results:
| Code: | PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

So I can ping my router, 192.168.1.1, but nothing past there but again this is all working from Ubuntu.

Do this in gentoo:
| Code: |
echo "nameserver 4.2.2.2" > /etc/resolv.conf
echo "nameserver 4.2.2.5" > /etc/resolv.conf
echo "nameserver 206.13.28.12" > /etc/resolv.conf
echo "nameserver 206.13.29.12" > /etc/resolv.conf
|
Also give us the output of "route -n"

That seems to have fixed it but I used my routers ip instead of those you gave. I am currently running emerge --sync from my chroot and it is working nicely. Any ideas how this got changed as it was all working before? Should I also add the adresses you gave to this file. I opened the file to see what was there before I run a command but stupidly opened Ubuntus instead but when I checked the correct one there was only the ip I had entered through the command in there. Does this mean that the file was empty before that?
Thank you so much all of you for helping.

Out of Africa now and everything seems to be working fine. Web browsing was good with just my routers ip as a name server but for e-mail and emerge I had to use one of yours. Currently emerging nicely. Thanks again.

The nameservers you were using might have been ISP centric. Or they could just be broken?
