Manually you could do:

ip addr add 127.112.113.xxx dev lo

To begin with ifconfig doesn't work on creating aliases and according
to rhel
docs I need to copy ethXxx files if I want to create these aliases.
Is there a better way,  than to copy files, to achieve the same?


What's the concern with making a new ifcfg-* file to create the alias?

It's as simple as on apple/bsd.

ifconfig ethX:Y inet $IP/$CIDR
ifconfig ethX:Y del $IP

Re: Network aliases

2014-07-28 Thread Andrew Z 
I havent figured out how to manage those files..
The original script creates dozens of aliases - one per destination, by
replacing first Xxx with 127. This makes it intuitive where alias "points"
to.
Now with each file having the same name (lo:) imnot sure how to
manage these aliases.

I want to add, that I suspect that im missing something obvious and/or just
dont understand how network stack works now.
Any help is very much appreciated, since all my information is from rhel
one page guide , some blog and just trying to get aliases to work.
