With one problem down I still have another remaining. Since the installation of our primairy webserver we have had a problem with the network aliasses. Our server has 8 IP adresses so we used the tool provided in the GUI to specify (and name - for our own convinience) eth0 aliasses with the other 7 adresses. After setting them up, applying them, activating them and restarting

I know this was discussed before, and I have seen a million ways of doing this via online docs. I have a quick question that hopefully the community can help me out with I am trying to add a block of 10 IP addresses. Rather then create 10 different alias files, I want to use the RANGE file. Docs say to use the following format: IPADDR_START=x.x.x.x IPADDR_END=x.x.x.x CLONENUM_START=0 If the

What's the right way to assign an IP alias to an ethernet interface that you want to bring up and down manually, not on boot? I tried the old way of making an ifcfg-eth3:0 file and it does work with the ifup, ifdown commands, but even though I specified onboot=no, it activated at boot-up. -- Les Mikesell lesmikesell at gmail.com

In CentOS 5.7 and earlier versions, an alias interface is defined via ifcfg-<interface>:foo which contains "ONBOOT=no". The ONBOOT setting appears to be ignored, and the interface always starts when the system boots or if networking is restarted. This is a serious bug that seems to date back many years (I found references in 2005). Anyone know why it hasn't been fixed, or

Hi, I accidentally found that the existence of a file e.g. named ifcfg-eth1:1 put in /etc/sysconfig/network-scripts/ leads to the appropriate interface being created even with the option 'ONBOOT' set to 'no': DEVICE="eth1:1" BOOTPROTO="static" NM_CONTROLLED="no" ONBOOT="no" TYPE="Ethernet" IPADDR=12.34.56.78
