reboot and network interface is not found

[typo3usa]

After reboot the network interfaces are not found.
I was able to find 1 by going in and editing /etc/networks/interfaces and changing eth0 to eth2

restarted network and voila - worked...
however now - it does not

any ideas - as this is getting tiresome...

i have 4 vps down on this node due to this :-(

hardware is a sun x2100 using on board nic's

i am told that eth0 cannot be found
:-(

same with eth1

Hi,
remove all lines after "# You can modify it..." in /etc/udev/rules.d/70-persistent-net.rules
After reboot you should get your eth0 back.
I think due a new driver udev renamed your devices.

thanks - sadly - while that allowed the interfaces to be renamed (awesome trick btw)
i still cannot ping the gateway

strange - really strange

 

[typo3usa]

in short - multiple systems running proxmox cannot ping their gateway
other systems non proxmox all ca

no vlan
nothing different other than proxmox being installed

any ideas?

in short - if we remove the network cable and then plug back in - they go down hard.
different switches ...

Hi,
what is the output of:

ip link show eth0
ifconfig eth0
ifconfig vmbr0
ip route
cat /etc/network/interfaces

ifconfig vmbr0 shows: error fetching interface information: Device not found

cat/etc/network/interfaces shows it however:

iface lo inet manual

iface eth0 inet manual

iface eth1 inet manual

auto vmbr0
iface vmbr0 inet static
address 98.100.x.x
netmask 255.255.255.0
gateway 98.100.x.1
bridge_ports eth0
bridge_stp off
bridge_fd 0

ip route - kinda large but does show the proper gateway

ip link show eth0
large again - but looks pretty normal

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisk pfifo_fast state UP qlen 1000
link/ether 00:22:19:b4:19:79 brd: ff:ff:ff:ff:ff:ff

Hi,
vmbr0 doesn't exist...
can you

brctl addbr vmbr0 eth0
ifconfig vmbr0 98.100.x.x netmask 255.255.255.0 up
ping 98.100.x.1

??
anything in syslog about vmbr0?
What is the output of

dmesg | grep vmbr0

address 98.100.x.x
gateway 98.100.x.1

hi, are those public ip addresses that you masked with x, i suppose?
