eth0 not active on startup
Admitted newbie here ... installed Red Hat 8 ... applied all packages to get current ( i.e. I got the blue check mark thingy).
PROBLEM IS ... if I log on normal (or the wife or the kids) ... we can't surf the net or get e-mail because eth0 is not active ... SO ... I go to "System Settings / Network" ... am prompted for the root password (which I enter) ... I get to the "Network Configruation" screen and I "activate" the eth0 device. From then on life seems good (well I do have some other things I'll be posting ... but I'll follow protocol for now). ALSO , I also noticed later ... as I was documenting this post ... that if I have already activated eth0 and I am later logged on as root and go to "System Settings / Network" ... I get the following popup message prior to gettting the "Network Configuration" screen ... "eth0 has an alias to module 3c501 in modules.conf, instead of currently loaded module 8139too!" :confused: Confused newbie needs help ! Any help always appreciated. |
Check in /etc/sysconfig/network-scripts/ifcfg-eth0 whether you have
ONBOOT=yes. Also check /var/log/messages and /var/log/dmesg for any complaints about eth0 Check /etc/sysconfig/hwconf and find out the type of ethernet card that has been detected |
You can also type dmesg | grep eth,
this will display the network card information and the eth device it is assigned. |
eth0 not active on startup
:newbie:
has followed up ok ... ppuru, thanks for the suggestion, but ... it's already set to yes ... contents of "/etc/sysconfig/network-scripts/ifcfg-eth0"are as follows ... # Please read /usr/share/doc/initscripts-*/sysconfig.txt # for the documentation of these parameters. USERCTL=no PEERDNS=yes TYPE=Ethernet DEVICE=eth0 HWADDR=00:10:b5:3b:a4:f6 BOOTPROTO=dhcp ONBOOT=yes ~ ~ ============================================= Mathieu ... thx also ... not sure what it means but here is the result of doing dmesg | grep eth ... $ dmesg | grep eth divert: not allocating divert_blk for non-ethernet device eth0 divert: no divert_blk to free, eth0 not ethernet divert: not allocating divert_blk for non-ethernet device eth0 divert: no divert_blk to free, eth0 not ethernet divert: not allocating divert_blk for non-ethernet device eth0 divert: no divert_blk to free, eth0 not ethernet divert: allocating divert_blk for eth0 eth0: SMC1211TX EZCard 10/100 (RealTek RTL8139) at 0xc8927000, 00:10:b5:3b:a4:f 6, IRQ 9 eth0: Identified 8139 chip type 'RTL-8139B' eth0: Setting 100mbps full-duplex based on auto-negotiated partner ability 41e1 . ============================================== no change in status ... eth0 still not active on startup :confused: |
perhaps you made a mistake in installing the ethernet card.try to plug out the card and restart linux,remove your net card configuration.and then plug in your card ,let the system recognize your card ,i think it will be ok
|
is the network daemon running on startup
|
Check /etc/modules.conf
and comment the alias entry that points to the 3Com driver (if you have only one network card on your system) Following jayakrishnan's suggestion, do a chkconfig --list network to verify network services are indeed started at boot. |
