[Fwbuilder-discussion] RTNETLINK answers: File exists

[Robin B. <rob...@ro...>]

Hi,

I'm using Firewall Builder v2.0.12 on FC6 to write firewalls for other
FC6 hosts.

I have one particular host that has 3 ips assigned to eth0, i.e.

eth0      Link encap:Ethernet  HWaddr 00:16:3E:3B:D6:4F
          inet addr:192.168.1.82  Bcast:192.168.1.255  Mask:255.255.255.0

eth0:1    Link encap:Ethernet  HWaddr 00:16:3E:3B:D6:4F
          inet addr:192.168.1.90  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

eth0:2    Link encap:Ethernet  HWaddr 00:16:3E:3B:D6:4F
          inet addr:192.168.1.91  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

I've added these to the firewall as additional IPv4 addresses in the
eth0 interface object.

When I install the firewall, I get the "RTNETLINK answers: File exists"
message. If I enable debugging I se this:

+ /sbin/ip -4 addr add 192.168.1.90/24 dev eth0 brd + scope global label
eth0:FWB1
RTNETLINK answers: File exists

and

+ /sbin/ip -4 addr add 192.168.1.91/24 dev eth0 brd + scope global label
eth0:FWB2
RTNETLINK answers: File exists


I'm not sure if this will cause a problem or not, but I'm having trouble
getting something else to work and I'm wondering if this is the reason.

Cna anyone shed any light?

Thanks,

R.
