ip ro get problem

ip ro get problem

[Sandro Dentella]

Hi all,

I'm using ip route get to debug a routing probelm and I get:

    root@fw-euronet argo # ip route get 192.168.254.10 
    192.168.254.10 dev eth0  src 192.168.254.1 
	cache  mtu 1500 advmss 1460
    root@fw-euronet argo # ip route get 192.168.254.10 from 192.168.5.2
    RTNETLINK answers: Invalid argument


What does really mean "RTNETLINK answers: Invalid argument", 


I get the same error w/

    root@fw-euronet argo # ip route get 192.168.254.10 iif tun0
    RTNETLINK answers: Invalid argument

My rules are:
    root@fw-euronet argo # ip ru li
    0:      from all lookup local 
    30:     from all iif tun0 lookup adsl 
    38:     from 192.168.254.10 lookup hdsl 
    40:     from 217.58.51.160/27 lookup hdsl 
    41:     from 81.121.243.248/30 lookup adsl 
    52:     from all iif eth0 lookup adsl 
    53:     from all iif eth2 lookup adsl 
    32766:  from all lookup main 
    32767:  from all lookup default 

where you can see that tun0, where 192.168.5.0/24 is, should look table adsl
that is define this way:

    root@fw-euronet argo # ip ro ls table adsl
    81.121.243.248/30 dev eth3  scope link  src 81.121.243.250 
    217.58.51.160/27 dev eth1  scope link  src 217.58.51.162 
    192.168.5.0/24 dev tun0  scope link 
    192.168.1.0/24 dev eth2  scope link  src 192.168.1.1 
    192.168.254.0/24 dev eth0  scope link  src 192.168.254.1 
    default via 81.121.243.249 dev eth3

	Very good question -- and althought there might be someone here who could 
answer this (and I too would like to know since I'm now mucking with iproute2 
and a dual route system) .. But this question would best be asked on a LARTC 
mailing list :

	subscribe here:
	http://mailman.ds9a.nl/mailman/listinfo/lartc

	archive here:
	http://mailman.ds9a.nl/pipermail/lartc/


	Good luck !

Sorry for that! I'm subscribed to both lists and I swapped the addresses
