I'm setting up VIPA's, zebra, quagga, and ospfd under my Redhat AS 4
zLinux running under VM 5.2 It nearly works, but not quite and I'm
hoping to get some insight from this list group.
I have an environment with two OSA's into a single Vswitch. On the
zlinux machine I have two devices:
eth0 10.1.100.17
Dummy0 10.0.17.10
Both devices start and can be pinged from within the zlinux machine.
Pings from the zlinux machine to anything on my network all work.
-- But --
10.1.100.17 is pingable from outside the zlinux machine but on my
network (i.e, my desktop)
10.0.17.10 is not pingable from outside the zlinux machine.
-- Except --
10.0.17.10 is pingable from a sister zLinux machine (a guest of the same
VM). Both use the same vswitch.
I've talked to my network guys and they report that the ospfd daemon is
working properly. They see it as a neighbor router and more so they see
a learned route table entry of:
10.0.17.0/24 10.1.100.17
It appears that my pings for 10.0.17.10 are indeed being properly routed
to the real address of 10.1.100.17, but after that I can't tell what
becomes of them. Thanks in advance for any clues of where to look.
I'll be happy to post the various config files upon request.
I've just been fighting routing/firewall issues on my (Intelish)
network. I found these to be extremely useful:
iptables (can log traffic, so logging icmp traffic might be helpful)
tcpdump (can capture traffic, maybe capture everything to/from the hut
(host under test))
ethereal/wireshark (displays the capture file from tcpdump more nicely,
doesn't have to be run on the same machine).
