Since I'm trying to get the ospfd ptp working as per the RFC, I
thought I'd better work on the most recent code. Previously I'd
been developing from the CVS snapshot of 2003/08/08.
However, with the config files and ./configure options I was
using then, I can't get OSPF to work with ethernet links
configured "point-to-point" at all -- let alone be able to
test my changes :-(
If I ./configure it without --enable-user=root, then it defaults
to user & group 'quagga', which exists, but when I execute zebra -d,
I get the error message "bind: Address already in use"
On the other hand if I ./configure it with --enable-user=root
--enable-group=root then it runs fine, but OSPF isn't enabled on
the interfaces I've configured as point-to-point :-(
I'm trying to run ospf over ethernet connections that I've
configured as 'point-to-point', by:
# ip addr add aa.bb.cc.dd/32 peer pp.qq.rr.ss/32 dev ethn
With the snapshot taken on 2003-08-08 this works without problem.
With the snapshot taken yesterday (2003-10-16) I cannot get it to
work.
With both codebases, it happily talks over "normal" ethernet
links, but over the point-to-point ones it doesn't even send
hello packets. When I telnet to the ospf daemon and issue the
show ip ospf interface command, it claims that the (point-to-point)
interface is up, but that "OSPF not enabled on this interface".
See the attached "session" for details...
Any ideas on
a) Why I'm getting the bind problem if I don't set the user to root
b) Why it's not working over the ptp link?
Or am I going to have to revert to an older snapshot?
Many thanks
