 |
|
Hi, my problem is the following:
I emerged updates with | Code: | | emerge --update --deep world |
Well everything worked well since about 1 week. Then i restared the machine (due to transport). First of all i couldn't login anymore (unable to find /bin/login was in dmesg). I copied the login file from live cd. Now i cant access the Internet anymore:
The interface is up:
| Code: | # ifconfig
eth0 Link encap:Ethernet HWaddr ...
inet6 addr: fe80::209:5bff:.../64 Scope:Link
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:1076 errors:0 dropped:0 overruns:0 frame:0
TX packets:540 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:90183 (88.0 Kb) TX bytes:22289 (21.7 Kb)
Interrupt:177 Base address:0x6000
/* snip */
ppp0 Link encap:Point-to-Point Protocol
inet addr:62.214.205... P-t-P:213.30.192.79 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1492 Metric:1
RX packets:605 errors:0 dropped:0 overruns:0 frame:0
TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:46326 (45.2 Kb) TX bytes:450 (450.0 b) |
Routing is set up: | Code: | # route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
213.30.192.79 * 255.255.255.255 UH 0 0 0 ppp0
10.123.0.0 * 255.255.0.0 U 0 0 0 eth1
loopback * 255.0.0.0 U 0 0 0 lo |
ppp with rp-pppoe-plugin sets the nameservers correctly: | Code: | # cat /etc/resolv.conf
nameserver 62.72.64.237
nameserver 62.72.64.241 |
I can ping the end point of my Point-to-Point connection (213.30.192.79 in this case), but any other ips are not available and names aren't resolved. I think this is, because the nameserver can't be reached, too.
| Code: | # ping 123.123.123.123
connect: Network is unreachable
# ping google.de
ping: unknown host google.de |
Any ideas?

| Did you update your configuration files? You would usually use dispatch-conf or etc-update. |

Me too. It helps to set up a manual route to the gateway, but it did work before!

as far as i can see u don't have a default gateway, meaning that the system doesn't know where to send a packet, if it is not from 10.123.x.x or lo! if u know your default gateway's ip (probably router) do:
route add default gw <default gateway's ip> |

in your /etc/conf.d/net add "-net" to the argument for the default via...
Should look something like this: | Code: | | routes_eth0=( "-net default via xxx.yyy.zzz.nnn" ) |
Don't forget to do /init.d/net.eth0 restart afterwards...
