Hi Offer,
All IPtables are off, both for v4 and v6.
Pinging from z/OS to zLinux does not work, nor does traceroute yield anything.
With all this said, I think it has something to do with the way I have routing
set up on the z/OS side. For all OSA traffic, I use OSPF while for
Hipersockets, I use static routing.
- The reason I think this is because when I do a traceroute from z/OS to z/VM,
it looks like the route is by way of my VLAN through the OSAs, though I have
defined it for all traffic to 5.5.5.0/24 to be routed through the Hipersockets
link:
CS V1R13: Traceroute to 5.5.5.2 (5.5.5.2):
1 10.82.10.44 (10.82.10.44) 6 ms 10.82.10.121 (10.82.10.121) 0 ms 10.82.10.44
(10.82.10.44) 0 ms
***
Just some notes... I do not have an OSPF interface defined for Hipersockets.
When I cancel the OMPROUTE started task, I am unable to ping or reach other
z/OS hipersocket addresses. I do have sourceVIPA turned on... would this be the
issue? At this point, I'm not too sure why its not routing via the static
route.

- A traceroute to other z/OS LPARs yield something different:
CS V1R13: Traceroute to 5.5.5.12 (5.5.5.12):
1 5.5.5.12 (5.5.5.12) 3 ms 2 ms 0 ms
***
- From zLinux and z/VM, it looks right, where the first hop is by way of the
Hipersockets:
[root@lsysg01a ~]# traceroute 5.5.5.12
traceroute to 5.5.5.12 (5.5.5.12), 30 hops max, 60 byte packets

Subject: Re: Hipersockets between RHEL and z/OS
Hi,
First thing i would do is make sure your iptables service is stopped and that
the ipv6 iptables is down as well...
Can you send the output of netstat route on z/os and route on linux?
Also does pinging the z/os from linux works??? That what i got from your first
email...
