Re: IP aliasing

Thanks,  Jesse

I will get an opportunity to try this out at a later
stage. I'm sure it will work, on provision that the
command works on a 'default' installation with
network support. I'm just amazed that even
the "100% comprehensive" Red Hat Linux 8
Bible does not appear to make any mention of the netconfig command. Neither
do any of my other RH books. There is not even a man page for it on my RH8
system. Hmmm ....
