Network Access on Different Segment

[kclee]

I do have 2 different segment network which different platform on each segment. E.g. 20 segment, Windows OS can "talk" to HP-UX OS and 21 segment practice same rule. Further more, Windows OS from 20 segment can talk to 21 segment other OS but only the HP-UX OS in 20 segment fail to talk to 21 segment.

Do anyone know how to troubleshooting this issue?

How is your network set up? Are these class A, B, or C addresses?

Do you have to go through a router to get from the 20 to the 21? If so, os your default route set up correctly on the HP-UX server?

What does 'netstat -rn' show?

What happens if you do a 'traceroute' from the HP-UX machine to a machine in the 21 segment?

Hi,

Sorry, I do not know what is the Class A, B or C. Maybe I will look into it first.

Btw, I do try the command to check and get the result. It look like permission deny but I wonder why other OS machine no this problem.

Can you advise on how to trouble shooting it?
