Gadi,
I was not sure of the problem, and where the specific started task comes in.
Can you ping the RHEL server from z/OS?
If the ping fails it could be due to two reasons
1. z/OS does not know about the RHEL address
2. The ping request got to RHEL, but RHEL does not know the route to get
back to z/OS.
TRACERTE ( on z/OS) and traceroute ( on RHEL) may help in this
On Ubuntu traceroute gave me
$ traceroute 10.1.1.2
traceroute to 10.1.1.2 (10.1.1.2), 30 hops max, 60 byte packets
1 10.1.0.3 (10.1.0.3) 0.285 ms 0.250 ms 0.167 ms
2 zos (10.1.1.2) 5.121 ms 2.271 ms 4.334 ms
The first hop ( 1) went via 10.1.0.3, the second hop (2) went via 10.1.1.2
on z/OS TSO NETSTAT HOME gave me
Home address list:
LinkName: ETH1
*Address: 10.1.1.2*
Flags: Primary
on z/OS tso tracerte 10.1.0.2 gave me
CS V2R4: Traceroute to 10.1.0.2 (10.1.0.2):
1 10.1.1.1 (10.1.1.1) 1 ms 1 ms 1 ms
2 10.1.0.2 (10.1.0.2) 2 ms 1 ms 1 ms
so the first hop(1) went via 10.1.1.1, the second hop went via 10.1.0.2
(from 10.1.1.1)
