Dear Ray,
Please assure me that:
/sbin/ifconfig eth0:0 xx.xx.xx.10 netmask 255.255.255.0
Is this the valid netmask " 255.255.255.0" for static IP address for this machine
you mentioned????
it will be "ifconfig eth0:0 xxxxx netmask 255.255.255.255 "
Regards,

Hi all,
I need to (quickly!grrr) update IP addresses for which a given machine
will answer.
I did this:
/sbin/ifconfig eth0:0 xx.xx.xx.10 netmask 255.255.255.0
/sbin/ifconfig eth0:1 xx.xx.xx.11 netmask 255.255.255.0
/sbin/ifconfig eth0:2 xx.xx.xx.30 netmask 255.255.255.0
/sbin/ifconfig eth0:3 xx.xx.xx.31 netmask 255.255.255.0
/sbin/ifconfig eth0:4 xx.xx.xx.13 netmask 255.255.255.0
/sbin/ifconfig eth0:5 xx.xx.xx.15 netmask 255.255.255.0
/sbin/ifconfig eth0:6 xx.xx.xx.20 netmask 255.255.255.0
/sbin/ifconfig eth0:7 xx.xx.xx.21 netmask 255.255.255.0
/sbin/ifconfig eth0:8 xx.xx.xx.22 netmask 255.255.255.0
but on looking at the output of /sbin/ifconfig, I see this:
