how 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.

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 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.
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.
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 1 Replies View RelatedI'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:

Can anybody explain how I can set a hostname alias in RHEL5. We are testing RHEL to replace our Solaris LDAP servers, one of the things we need is to be able to set a hostname alias on the public interface.In solaris we can just update the /etc/hosts file to something like
ipaddress hostname alias1 alias2
Things looks alittle different in RHEL, the host file only contains
127.0.0.1 hostname.fqdn localhost.localdomain localhost
I read about the sysconfig/network files but can only see about changing the hostname there and nothing about setting a different alias.
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
ONBOOT=yes

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 installed RHEL-5 (2.6.18-53) on my Desktop (ASUS Motherboard with Realtek PCIe GBE Family Controler 8168). After installation eth0 is not detecting. I downloaded R8168 drivers from Relatek site, but I am unable to install as it's throwing the following error.

View 2 Replies View RelatedI've noticed that when Linux boots on different machines or with different versions, the network card is assigned to eth0 or to eth1, when there is only one network card. What is the difference and is there any way to tell which one it will be for any machine or version?
View 3 Replies View RelatedI have setup a dual boot machine which has OS of Windows Vista (32 Bit) / RHEL 5. The LAN Card details are - Atheros L2 Fast Ethernet 10/100 Base T - Controller.

View 1 Replies View RelatedI know this is a relatively simple problem but no matter what combination I try for my alias, I don't seem to be able to get it right! All I want to do is scp a file from my current folder to a location on the network:
Code:
scp filename username@computername:/folder1/folder2
This is the usual layout of the command that I use, so I thought that to save time, I would create an alias or even a function which did this for me, so all I had to type was
Code:
scp101 filename
and it would copy it to the set folder on the remote computer...
My attempt at an alias looks like:
Code:
alias scp101='scp !* username@computername:/folder1/folder2'
and I have also attempted a function:
Code:
scp101()
{
scp "$1" username@computername:/folder1/folder2
}
The alias tells me that filename is not a directory, which I assume means that I have some of the syntax wrong in the alias but I did a google search and I can't seem to find a decent example of what I'm trying to do. When I load up a terminal, I get an error message about the "(" of the scp101 function - so I've obviously can't get the syntax of that right either...
i have a big problem y have to make an alias for the eth0 interface, i made it with yast and my alias was eth0:1, first, if i try to shutdown the interface i cant it give an error and tell me that the interface dont exist and the second threat is if i can put a default gateway for this alias something like this in other distributions:
route add 128.26.6.11 gw 192.168.28.201 dev eth0:1
I am using FC 2, and I get 'eth0 failed' during startup.
I am configured for DHCP
device is 'inactive' under network device control after reboot
click 'activate', sometimes I can surf, others not.
When I can't get online, sometimes deactivating and reactivating works.
edited connection to 'activate device when computer starts'
eth0 still fails at start-up, and device is inactive.
I am supposed to use FC2 for my schoolwork
I'm running Ubuntu Server 10.04 to provide DHCP and Internet Sharing on my home LAN. In a previous configuration, I was running Fedora + AMAHI to provide the same services. As most of my linux devices are Ubuntu, I decided to decommission and rebuild my server. I've been able to configure all of my services with the exception of one. As a rule, I assign static IP or reservations based on MAC address's for any of my network devices or appliances.
One cool feature that AMAHI provided a GUI for, was the ability to recognize devices by name as well as IP. i.e.. "http://192.168.1.50" or "http://home-NAS" Going from memory, the long name upon first entry may actually have been "http://home-NAS.adomainname.com"? From my reading, I think I either need to setup up a Static Alias or CNAME for each assigned IP. I can't find any tutorial's that will walk me through this process. I'm guessing I need to generate the records under one of the master DNS zones, but that is just a guess?
I wish to install a C++ plugin for the Eclipse IDE.I have Fedora 10 installed.I goto:
1. System-->Administration-->Add/Remove Software
2. I type 'eclipse' in the seach box and hit 'Find'.
3. From the list of packages available I select 'Eclipse C/C++ Development Tools (CDT) plugin.
3. When I hit 'Apply' I get an error message saying 'No Network connection available' The 'more deatils' tells me: 'Cannot install when offline'
But my computer IS online. I have internet access etc.
If I uncheck and recheck "Enable Networking" in the Network Manager Applet 0.7.996 I would expect the wired network to disconnect (which it does) and reconnect (which it does NOT). So I tried sudo ifdown eth0 and got
