removed NetowrkManager, now no eth0 connection

[methos]

I feel like an idiot. I removed NetworkManager by mistake (bam! palm to forehead). Now I feel even dumber because I can't get my network connection working again (smack! palm to back of head).

Please excuse the excess information, I'm not sure what is pertinent and what is not.

My network looks like this:

Linksys router with DHCP enabled -> Linksys switch -> several F10 boxes

I am using DHCP Reservation on the router for all machines to have static ip address, except the one in question, I removed that reservation while trying to get my connection back.

I am not running a DNS server.

After a great deal of "googling" and many attempts to get the ifcfg-eth0 configured correctly on my desktop (i.e. not using wireless) I am at a loss. Any assistance is greatly appreciated.

I have been making all of my changes to the file:
/etc/sysconfig/network-scripts/ifcfg-eth0

Are there other places I need to make modifications? Here is what the file currently looks like:

DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:50:2c:...
ONBOOT=yes
USERCTL=no
PEERDNS=yes
IPV6INIT=no
NM_CONTROLLED=no
TYPE=Ethernet
BROADCAST=192.168.2.255
GATEWAY=192.168.2.200 (the ip address of my router)
NETMASK=255.255.255.0

I appreciate any suggestions you may have.

im not an expert but have u started network service? as far as i know when we disable/remove network manager, we need to start 'network' service. then use our old style

system->administration->services->turn on network
#ifup eth0
#service network restart

I think you need to put sets if you want fixed ip the next line:

IPADDR=192.168.0.2

and if you want DHCP connection:

BOOTPROTO=dhcp

nick192 - yes the network service has been started. Actually I've made so many attempts that I have even rebooted several times to make sure there were not also other services that needed to be restarted.

pages.pedro - perhaps I'm not quite understanding what you mean but the router is doing DHCP and I have that set it the file ( BOOTPROTO=dhcp ) which is why I didn't set a specific ip address. The router handles static ip address reservation based on the MAC address of the machine, but these have to be set to be reserved, otherwise it acts as a regular DHCP.

Go to System> Administration>Network>Devices
Is Eth0 there? probably will say inactive, check the box, Activate it, save, it should activate.

If its not there check the hardware tab first it should be there, create a new device for it.

[methos]

Tried that several times. Eth0 is there / was there. When I try to activate it the window comes up that would normally show the progress, but it is blank and only up for a second then back to the network window where eth0 is still inactive. I have tried saving and restarting the network service, even removing and adding it back, same deal, will not become active.

Unfortunately NM has lots of dependencies.
Did you delete the device from hardware as well and then reboot?
You might try to force a reinstall of network.
Did you reinstall NM

try removing eth0 n adding it again .. as it helped me once
