hi!
I'm trying to configure IP Aliasing.I was able making that by creating a new file ifcfg-eth0:1 and that was ok,and after rebooting.
Now, me was suggested to follow this howto http://www.faqs.org/docs/Linux-mini/IP-Alias.html
but after rebooting it doesn't exist.There is a sugestion to do for that but for me is not working.Any suggestion ???I'm using RHEL5.
thank you

Check out this link to add a file called ifcfg-eth0:0 in /etc/sysconfig/network-scripts

ok,brian thanks for the link but I have done this type of configuration. I'm asking for this configuration:

/sbin/ifconfig lo 127.0.0.1
/sbin/ifconfig eth0 up
/sbin/ifconfig eth0 172.16.3.1
/sbin/ifconfig eth0:0 172.16.3.10
/sbin/ifconfig eth0:1 172.16.3.100


/sbin/route add -net 127.0.0.0
/sbin/route add -net 172.16.3.0 dev eth0
/sbin/route add -host 172.16.3.1 dev eth0
/sbin/route add -host 172.16.3.10 dev eth0:0
/sbin/route add -host 172.16.3.100 dev eth0:1
/sbin/route add default gw 172.16.3.200


etc... Has anyone done this type of configuration in RHEL5.
greetings

If those are the exact steps you enter to get it up and running then place those commands with their full path like you already have. Place those commands at the end of /etc/rc.local. That would be the easiest.

...I'm probably more of a newbie than you are so take my suggestion with a handful of salt.
(...if I'm way off base here, someone please feel free to humiliate me publicly %-)

It seems to me, with my < VERY LIMITED > experience that configuration setting in an if-cfg file in /etc/sysconfig/network-scripts/ don't seem to get applied consistently after a reboot.

If you use the GUI Networking utility to configure an interface, you will find that it creates the if-cfg file in /etc/sysconfig/networking/devices/

I have therefore found it helpful to copy all the if-cfg files I want to maintain after a system reboot to this secondary location.

Bottomline: Try putting your if-cfg files in /etc/sysconfig/networking/devices/ and see if that causes your IP alias settings to be maintained across system resets.

...RHEL is the only distro that I have really worked with, so all of the proceeding is based on my (possibly flawed) observations of the workings of RHEL4 and RHEL5...other distro's may not exhibit these behaviors ...hell, RHEL may not even exhibit these behaviors at the hands of someone who knows what they are doing. %-)
