Hi Euan, a couple of comments : * Alias interfaces cannot be "upped", ie you cannot ifconfig xxx:0 up (hence you get the "Cannot assign requested address" message). Issuing a "ifconfig xxx:0 11.22.33.44" will do fine. * Once you have defined the config file, the right command to activate the interface is "ifup xxx:0" . * You might want to add the "ONPARENT" attribute to the alias config files, such as : # cat ifcfg-eth1:1 DEVICE=eth1:1 ONPARENT=yes BOOTPROTO=static IPADDR=172.16.192.5 NETMASK=255.255.255.0 Cheers On Fri, Oct 15, 2010 at 11:38, Euan de Boer <euan.deboer@xxxxxxxxxxxxxxx> wrote: > Hi, > > Sorry if this posts twice (first posting seems stuck awaiting admin > approval). > > I am looking at binding 64 IP addresses to a Redhat 5 server with dual > NIC's.
