Re: mysterious routes appearing



Oops :-{

Check to see if you are running ;
routed, gated or zebra.

They are all routing deamons, I know someone asked if you were running RIP or OSPF.

IIRC all three support RIP, but I think gated and zebra support other routing protocols as well like
IGRP.


As root, check what network services you are running with :

netstat --inet -lp

---sample---

udp 0 0 *:ntp *:* 590/ntpd

---end---


RIP runs on {from /etc/services}:
router          520/udp         route routed    # RIP

Maybe this will be helpfull :-)

Hi

I will annotate the routes in question for you.

Thanks for the help, but you explained the ones I already know! As I mentioned, the three routes that are ok are:


The ok routes are obviously 2, 4 & 5.
172.16.0.0      0.0.0.0         255.255.255.0   U     0      0        0 eth0
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo
0.0.0.0         172.16.0.4      0.0.0.0         UG    0      0        0 eth0


the 'others' are 1 & 3:


203.16.234.0    172.16.0.8      255.255.255.0   UG    0      0        0 eth0
203.39.28.0     172.16.0.4      255.255.255.0   UG    0      0        0 eth0


Its these two that I can't get rid of which is a nuisance, as they were ok once but now I don't want them.


It should be in /etc somewhere.. grep -r 203.16.234 /etc 2>/dev/null


By the way David, I tried this the other day as well, but nothing came up... grep seemed to 'hang' though, so I'll try again :(


I think that if you are having connectivity problems


I'm not :) except for the routes that I can't get rid of
