I have a server CentOs ver.6, and i have a hardware with 3 network cards. With startup i have 3 eth interfaces: eth0, eth1, eth2 (internal card and 2 pci express cards). How disable network card in... [by cmepthik]
I have a sever with 2 network cards, an internal IP on one card (eth0) and external IPs (aliased) on the other card (eth1). I lost connection the public network and I tried to restart networking with /etc/init.d/networking restart and got the error "SIOCSIFFLAGS: cannot assing requested IP and Failed to bring up eth1".
I'm running a Fedora 10 box behind a Comcast cable modem that provides squid and mail services to 15 XP and Vista workstations. I upgraded the ethernet cards on our Fedora box to support our new 1 gigabyte network.
I've Red Hat 5.7 on HP Blade BL460C G7.
Till yesterday I had 4 network devices configured as following:
bond0 = eth0 + eth1
bond1 = eth2 + eth3
This morning without apparent reason the eth0 and eth1 seems dead and the Blade are unreachable (I can login only using ILO).
I double check the hardware, and BIOS correctly seen the network cards, so something goes wrong on red hat.
I'm new to Linux, trying to get a Clonezilla server up.
I'm really bad at understanding how my network should be configured.
eth1 is the card for internet access, behind a proxy (192.168.41.5:80)
eth2 is the card for deploying, connected to a router.
When eth2 is running, I can't seem to connect to the internet as it automatically try to use eth2 for everything (Firefox, ping, apt-get).
