I am using your method, however it may be an earlier version.
if [ -f /etc/hostaliases ]; then
set -- `cat /etc/hostaliases`
while [ $# -ge 2 ] ; do
ifconfig $1 inet alias $2
route add $2 localhost
It has been suggested that perhaps I need to be setting a netmask as well..
As pointed out in earlier mail, these aliases are accessible from the
outside world, but not on the local machine.
