I have 2 10gb fiber cards on a server running red hat 5.3, eth4 and eth5. After replacing the eth4 card, it doesnt show up any ifcfg-eth4 file. I tried ifconfig -a, but it doesnt show up in modprobe.conf either, although it is listed when I do a lspci. Should I manually add it? or is there something Im missing here?
View 5 RepliesMissing ifcfg-eth[2-5] fileset for ZNYX 345Q Quad Port 10/100 cards. I have showing in the gui network device that my ports for my ZNYX ZX345Q Quad Port card my ports are Auto eth2, Auto eth3 etc. My Motherboard and Intel cards show as System eth0 and System eth1.
There ARE corresponding entries for those in my /etc/sysconfig/network-settings/ directory, but there are not ifcfg-eth[2-5] files to correspond to these adapters. Can I just write my own files and that will do it?
How does Fedora 12/13 load these drivers into the kernel without having these ifcfg files?
I'd love to know if there is another way Fedora controls NICs / other system resources.
When I do service network start it is giving me the error grep : can not find directory ifcfg-ifcfg-eth0....
For some reason it is adding another ifcfg to my ifcfg-eth0 file.
(and new-ish to Linux in general) and would appreciate some assistance with fixing a problem I'm having with getting wireless working on my computer.Computer specs: Lenovo Thinkpad Edge 520, I5Wireless card: Intel WiFi Link 1000 b/g/n(Note: I also have a Netgear USB wireless adapter, and trying to use this does not solve my problem)I cannot activate wireless. When I go to Network Settings > Wireless, it is listed as "unavailable", and "off". When I try to switch wireless "on", it says "disconnected", but then immediately switches back to "off".Having tried to browse various forums and such for a solution, I tried looking for the file ifcfg-wlan0 under /etc/sysconfig/network-scripts, but it doesn't exist
View 4 Replies View RelatedRunning Centos 5.5 64bit. Sometimes I boot this instalation in real machine, sometimas using vmware workstation. The problem is that these environments have different network interface cards - as soon as kudzu detects that network device changed it renames ifcfg-eth0 to ifcfg-eth0.bak and places new default ifcfg-eth0.
Is it possible to command kudzu to leave ifcfg-eth0 as it is ?
I've been racking my brains over the past few days trying to figure out why my NIC card (network interface card) won't show up in the ifcfg-eth0 file.When I configure a new server (like this one) I always go to:/etc/sysconfig/network-scripts/ifcfg-eth0 and from there I usally see the name of my NIC's manufacturer's name and the hardware MAC address.Then it's only a simple process of entering the server's IP address, netmask and gateway and I'm up and running in no time...But not in this case! the ifcfg-eth0 file is completely blank! There's not ONE single line of config info in it... (?)The server runs an Intel core 2 duo (dual-core) CPU with 1 gig of RAM.
I've even re-formatted the drive and re-installed Centos 5.1 on the darn thing 3 times and it simply won't work.The server cannot resolve when I do a wgetIt also gives me a 'resolution problem in the named configuration'.What I don't understand is that the 2 small LEDs on the Cat 5 cable lights up and flash at what appear to be regular intervals here.
I run a VMware clone of CentOS 5.3, I observe that kudzu [i.e. /etc/init.d/kudzu, from /etc/rc3.d/S05kudzu or /etc/rc5.d/S05kudzu] detects a MAC address change on eth0 and then creates a /etc/sysconfig/network-scripts/ifcfg-eth0.bak file. This .bak file is identical to the original ifcfg-eth0 file except for the value of the HWADDR [i.e. MAC address] parameter. I would be unconcerned but for the fact that /usr/bin/neat indicates that both ifcfg-eth0 AND ifcfg-eth0.bak are 'Active'. The following solution may help others with the same (or similar) problem:
[Code]...
I'm nearly at the end of creating a shell script that automates changing network settings by prompting the user for desired settings, then applying them.
In the course of my development, I created temporary copies of /etc/sysconfig/network-scripts/ifcfg-eth0 (/etc/sysconfig/network-scripts/ifcfg-eth0_tmp1, for example) so as to not alter the original file. Little did I know that on boot the system would attempt to load each of these kinds of files and associate it with an ethernet connection, in this case eth0.
So..... now there are multiple copies in the /etc/sysconfig/network-scripts diretory that essentially have the same settings. They are..
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth0_tmp1
/etc/sysconfig/network-scripts/ifcfg-eth0_tmp2
Now when the system boots, it attempts to load them all. The boot doesn't appear to complete, and I can't ping, login, or otherwise access the system through convention routes (putty, etc.).
The easy solution would be to delete the tmp files and reboot. Now, how do I do that without being able to log in to the server. It's a VM by the way, if that makes a difference.

View 10 Replies View RelatedI am having a problem when creating alias in Fedora Core 10. When i create a file like "ifcfg-eth0:1" and put contents in it like
DEVICE=eth0:1
BOOTPROTO=static
IPADDR=ip addrss
Netmask=Netmask
and when i save settings and restart with "service network restart" the network card does not create any alias like eth0:1 instead it replace the original ip address of eth0 with the ip address i given to eth0:1. So i want to keep both network ips of eth0 and eth0:1.
Running CentOS5.4 on home-build.The wireless card setup is working,at least with regard to internet access through a Linksys router.Trying to set up Windows shares using SAMBA has been problemmatic. After many searches the ifcfg file seems to be a mystery. So what is meant by the "ADDRESS0=" in the ifcfg-wlan0 file. it is the ""the NETWORK that matches the NETMASK". But even that I cannot quite understand (apparently) as my efforts to enter different items in this file have all failed.

View 1 Replies View RelatedNetworkManager is a powerful tool for setting up a wlan connection, especially if you connect the laptop to multiple access points. One drawback is that the user accounts must be given access to the pass
phrase. Another is that there is no wlan connection in run level 3, because nm-applet is an X application.If you connect to the same access point all the time, e.g., your own wireless router, a permanent connection via ifcfg might be more convenient. It is controlled by root. All user accounts have wireless access without knowing the underlying details. Further, there is a wireless connection in run level 3. After a lot of trial and error and Google searches, I was able to put together this guide by splicing together one step used in Slackware (from Alienbob's web page) with other steps outlined in this online article http://home.roadrunner.com/~computer...hwireless.html.
It is assumed that the appropriate kernel module for the wlan card is installed and that
$ iwconfigshows a viable wlan0 interface. We are using DHCP. (If using static IP, edit ifcfg-wlan0.)The following steps work on a Compaq Presario F756NR notebook with a Atheros AR242x 802.11abg WLAN card using the ath5k kernel module (without madwifi).

If so, skip.2. $ cd /etc/sysconfig && vi wpa_supplicantInsert the following lines:

View 3 Replies View RelatedI have just upgraded a CentOS 5.2 box to Centos 5.3
I did have a bridged networking setup for Virtualbox which worked well. eth0 was bridged with br0. br0 boot protocol was DHCP and it sent its DHCP_HOSTNAME to the windows DHCP servers.
since the upgrade the br0 does not get an address but the eth0 does. I found that the scripts in /etc/sysconfig/network-scripts/ifcfg-* are getting rewritten.
I figure I may not need to have a bridge any more so I stripped that out to try to get a simple network setup working. I now just have eth0. I edited /etc/sysconfig/network-scripts/ifcfg-eth0 so that it looked like this,
~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Attansic Technology Corp. L1 Gigabit Ethernet Adapter
DEVICE=eth0
BOOTPROTO=dhcp

When I setup the server I added multiple ips. Now that I need to edit ip info I can't find any alias files in the network-scripts folder. But restarting server the ips work fine. Is there some where else that this would be stored.
