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.
View 2 Replieshow to remove the network alias (ex: ifcfg-eth0:2)from RHEL5, i had deleted the ifcfg-eth0:2 file from /etc/sysconfig/network-scripts/ifcfg-eth0:3but i can still see the entry in the graphical network configuration after i issued the command system-config-network, i want to remove it from there.

For some reason it is adding another ifcfg to my ifcfg-eth0 file.
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 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

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:

I know I can rename my network interfaces (eg 'eth0' to 'lan', 'eth1' to 'net' etc) but does anyone know a way I can alias (symlink if you like) 'lan' -> 'eth0'
I want to be able to use more legible interface names in things like iptables rules (such as "-i lan" instead of "-i eth0") but I don't want to break any config that is expecting eth0 to exist....
I having a problem with my network. I'm trying to assign an IP alias of eth0:1 to eth0. If I use ifup eth0:1 is fails and corrupts the network. Making the network useless. But if I just enter 'ifconfig eth0:1 10.1.1.51', it work fine? My scripts look like these:
Code:
:network-scripts; cat ifcfg-eth0
NAME="System eth0"
DEVICE=eth0

I 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.
I have using fedora 10 on IBM Z60m Laptop, and my eth0 is not been up even is "ONBOOT=yes" in /etc/sysconfig/network-scripts/ifcfg-eth0. why I have to make it up every time

View 6 Replies View RelatedI'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.
I'm trying to do some network bonding in RHEL 5.4, and I'm not seeing the results I expect. I have set up a number of servers using mode 1 with no issue, but I need to configure a new server differently. bond1 is created from eth1 & eth2 bonded together using mode 802.3ad with layer2 lacp bond0 is created from bond1 & eth3 using mode active-backup with bond1 as the primary interface When I bring the network services up, all traffic is passing over eth3 instead of bond1, which is the primary. Below are the modprobe.conf * ifcfg-* files involved.
My modprobe.conf:
alias eth0 e1000
alias eth1 e1000
alias eth2 e1000
alias eth3 e1000
alias scsi_hostadapter mptbase
alias scsi_hostadapter1 mptsas

I've seen this pop up a few times on the forum but my setup is slightly different. I have a PC with an ASUS P5N32-SLI Premium motherboard. I've just installed CentOS 5.1. Yes, I know this is ancient, but this is what they're developing on at work. I'm trying to get connected either via ethernet or wireless and neither one works. When I boot the computer to Window XP it does connect on ethernet. Ethernet should be easy so I'm concentrating on that. But I get "Determining IP information for eth0... failed." after a 'service network start'.Here is some other information that was asked on similar threads:

New to CentOS5.5 I'm experiencing some trouble in order to continue my configuration. I've just installed my vmware tools and configured my network card with system-config-network
Edit eth0 (eth0) - vmxnet3 -> with a static IP I rebooted my server and since then I lost my eth0. I still see it in system-config-network, but I can't active it anymore.:
/etc/init.d/network start Bringing up interface eth0: Device eth0 has different MAC address than expected, ignoring. [FAILED]
I'm having a problem and despite I have googled a lot cant find the root cause. I have a server with two embedded NICs and centos 5.5 loaded. I need to have one NIC with a fix internal IP address to communicate with the intranet and a second NIC with a fix address from my telephone provider. I know I cant have two different gateways on the net so I configured only the gateway for the second NIC leaving the field empty for the first.
I found that the first NIC is handling all the traffic for both interfaces (eth0 and eth1) and the second NIC is in standby (or doing nothing). This is causing the traffic intended for the second NIC never reach their destination. After a couple days working with the BIOS and other configuration files I tried another way of solve the issue. I put a fix address for the first NIC and another fix address for the second NIC (both in the same subnet) and from a computer pinged successfully both addresses. However if I disconnect the cable for the first NIC both interfaces goes down (eth0 and eth1) and both pings fails. If I disconnect the cable for the second NIC (with the first one connected) both pings still running without any disturbance.
I worked also in a second server with different hardware (different kind of motherboard, different NIC manufacturer, etc.) but the problem is also present in this second server. I was reading about NIC bonding or teaming, but this configuration is not present in the modprobe.conf or in the ifcfg-eth0 files, so I believe the problem is not related with this feature. Do you know what is happening with the NICs and how can I get two really, fully independent NICs?
I have 2 network interface on 1 server and i got a problem finding a solution for it.I have 1 java application and i want it to use the eth1 for that application and not the default eth0. On eth0 i got for example xx.xxx.xx.22 and on eth1 i got xx.xxx.xx.23 and i want the java app to use the 23 ip one.
View 3 Replies View RelatedI am currently working to get to a stable dual boot Win7/CentOS 5.5 configuration on a Dell Latitude E6510 with the Intel 82577LM chipset. I haven't gotten the Centrino N WiFI chipset working yet, but the Eth0 device was working just fine.However, yesterday I did a system update. I did not pay close attention, but I believe the update did mention networking, because I thought it might help me get my wireless going. Now, Eth0 fails with the message, "Determining IP information for eth0... failed; no link present. Check cable?" It does this at boot up and if we try reactivating it once the system is up. We have tried unstalling and re-installing the driver.The Window 7 boot sees the adapter and runs just fine. I was at a different site location yesterday when everything was working, but my co-workers and I can't help but think it might be related to the update yesterday, since everything worked prior to the update and Windoze 7 works fine with the adapter.
I have not been able to mount my NTFS harddrive on the CentOS side, despite installing fuse, and I don't have wireless, which makes it difficult to get access to new drivers. I also have a FAT32 partition that would be great to share between the boots for passing info, but I haven't found a way to mount a FAT32 partition in CentOS.
Everything worked fine until very recently, and without apparently ANY change to the settings on the server, a secondary IP that was assigned to my server won't work anymore..Any IP attached to the same server works fine.. So in my case, the problematic IP is 213.8.155.67. The other IP (213.8.155.42) works without any problem.How would I go about troubleshooting this?
