Hi James,
To do the upgrades for Slackware 3.0 to Linux 2.0 please find the
information at 'http://www.cris.com/~hallow/linux'. This is a good outline
about upgrading to 2.0, it worked for me. and my rc.inet1 follows. You will
find 3 additional ip's after the initial definition. Just use ipconfig and
it will list the aliased ip's but won't show that they go to a NIC. It works
anyway. This is a good way to get multiple ip's for Apache Web Server. Any
more questions, just ask. - Andy
