 |
|
Hi,
today I rebootet my gentoo machine and now I have no network connection. On booting up I get "udev starting....!!" but the rest seems to work. Later I get an error "Adding routes default gw....!!". Bringing up eth0 seems to work.
ifconfig returns eth0 but without IP address:
eth0 Link encap: Ethernet HWaddr 00:26:54:15:83:1C
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
...
route add returns "SIOCADDRT: No such device".
Any idea?  |

I removed the udev-Error (inotify was missing in my kernel) but the network is not working yet.
Any ideas? |

if you comment out the routes_* parts,
you should get an IP on your cards,
when you then try to ping your gateway:
| Code: | | ping -c 2 -I eth0 192.168.2.1 |
what does it output?

so if you leave out the routes_* part
does your ethernet interface an IP?

No error messages on the console.
After that, my eth0 has an IP, but a ping returns network unreachable... |

I just read /etc/conf.d/net.example :
| Quote: | ##############################################################################
# INTERFACE HANDLERS
#
# We provide two interface handlers presently: ifconfig and iproute2.
# You need one of these to do any kind of network configuration.
# For ifconfig support, emerge sys-apps/net-tools
# For iproute2 support, emerge sys-apps/iproute2
# If you don't specify an interface then we prefer ifconfig it it's installed
# Prefer iproute2 over ifconfig
#modules=( "iproute2" )
# For a static configuration, use something like this
# (They all do exactly the same thing btw)
#config_eth0=( "192.168.0.2/24" )
#config_eth0=( "192.168.0.2 netmask 255.255.255.0" )
|
try using those commands, and as modules:
| Quote: | | modules=( "ifconfig" ) |

if you start:
| Code: | | /etc/init.d/net.eth0 start |
and if it stats without errors, then it will also do while booting (same for eth1)

please check if bash-3.1 was installed. if youre using an ustable baselayout try to downgrade to bash-3.0-r14 for example.
