>Environment:
I am trying to configure a machine to respond on multiple (ie. > 20)
addresses by having lots of aliases on the ed0 interface. The aliases
are on a different network number to the main address on ed0. I also
need to use gated to propagate routing information about this network.
Here is my /etc/gated.conf:
!#traceoptions route;
!
!rip on {
!# traceoptions packets;
!# traceoptions send response;
! interface ed0 ripin ripout;
! interface tun0 ripin ripout;
!};
!
!#egp off;
!#bgp off;
!#hello off;
!
!# for ICMP packets
!redirect on;
!
!#static {
!# 203.16.210.0 interface lo0 retain;
!#};
!
!#
!# Accept only RippleTech's net from Thebarton.
!#
!import proto rip interface tun0 {
! 203.16.208.0 mask 255.255.255.0;
! all restrict;
!};
!
!#
!# Propagate our nets to the IPA rack.
!#
!export proto rip interface ed0 {
! proto rip {
! 203.16.208.0 mask 255.255.255.0;
! all restrict;
! };
! proto direct {
! 203.16.210.0 mask 255.255.255.0;
! all restrict;
! };
!};
At startup, I add the aliases to the ed0 interface by adding the following
commands to /etc/netstart (after the for loop which ifconfigs the network
interfaces and before the bits which set up default route):
!# XXXX Adrian's additions for multiple address response on the local machine.
!for addr in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23; do
! ifconfig ed0 203.16.210.$addr alias netmask 255.255.255.255
!done
Here is my /etc/sysconfig:
!#!/bin/sh
!#
!
!# This is sysconfig - a file full of useful variables that you can set
!# to change the default startup behavior of your system.

>Description:
The alias addresses on the ed0 interface aren't reachable once gated
is started. I can't even ping them.
>How-To-Repeat:
Configure a machine with the files as shown above (with different network
numbers and without the tun0 driver stuff, which I don't think is the
cause of the problem), and after a reboot, try "telnet <addr>" where
<addr> is one of the aliases on the ed0 interface. The connection doesn't
work - it prints the error:
telnet: Unable to connect to remote host: Permission denied
>Fix:
I don't know. If you just define a small number of aliases by hand after
startup, it seems to work ok, but restarting gated causes the problem
to resurface (I think).
To be honest, I suspect this is my inability to configure gated correctly
:-)
Many thanks,
