Need help in scps

[karthikeyanr]

Hello guys,


Please anyone tell me how to configure SCPS Gateway between two end systems.
I have configured , but i could not run successfully. Both end systems could not communicate each other after running gateway command on both systems. Please provide me a solution.


Thanks,
karthikeyan R

both systems could not communicate means what.
can you do ssh to both systems, if yes then it will work

if you can send the logs it will help.
