Netmask should be 255.255.255.255 on a alias if it is from the same network 
as the primary address.

You already assigned this address?!?!?!

Re: Adding IP's ifconfig problems

2004-11-05 Thread GRF . 
I should have just left the IP's in untouched.  I know that looks suspicious 
but they are two different IP's one is lets say 178 and the other 179, they 
arent used twice.  But good catch.

Classic error.  You need to read this part of the ifconfig(8) man page
more carefully:

 alias   Establish an additional network address for this interface.  This
 is sometimes useful when changing network numbers, and one wishes
 to accept packets addressed to the old interface.  If the address
 is on the same subnet as the first network address for this
 interface, a non-conflicting netmask must be given.  Usually
 0x is most appropriate.

ie. only one address (per network) on the interface can have the
'real' netmask.  The others (ie all of your aliases) should use
0x or 255.255.255.255.  Or to put it another way, the bitwise
'and' of the IP number and the netmask must be different for every
address configured on the interface.

Cheers,

Matthew
