ifconfig eth0 up does not 'revive' eth0

**Figured it out. In addition to turning the NIC back 'up', I have to restart the network service.

# /etc/rc.d/network stop
# /etc/rc.d/network start

Problem solved. Lock thread please

--------------------------
I turn off my NIC card, eth0, by typing in the command:

Code:

ifconfig eth0 down

NIC is off, which is great. I then do:

Code:

ifconfig eth0 up

I can ping my LAN nodes, but I cannot reach anything outside the internet. Not even pinging by website name or IP address works. What else do I need to reinitialize eth0? Just trying to figure this out of curiousity.

This means that the NIC is working.

And this could indicate that something may be amiss in DNS, gateway settings, etc.

Are you using a static IP or DHCP? On my Debian box these settings are stored in /etc/network/interfaces, but that could very well be a distro-specific location. If you're DHCP, you might try running dhclient manually (it's dhclient on Debian - I think - but other distros may use something else).

Thanks for the help, haertig.

I solved my problem by simply restarting the /etc/rc.d/network service in addition to using

Code:

ifconfig eth0 up
