Re: ACS System Debugger doesn't want to work

Yep! You cannot do it on PUB400 ... I recently spoke with Holger about this problem (I have the same problem on my own partition).
He thinks it is because the IBM i is accessed directly ... without any VPN (and this might be the problem).

Well, that's strange because I just tried to debug an ILE and and OPM CL program with this System Debugger (initiated from iACS "Run SQL scripts"), and I was successful to do it on PUB400. It was using 4026 tcp port.

On my laptop, I ran, at the same time, a Wireskark network capture and all IP packets were initiated from my workstation (behind a NAT router, so using a non-routed IP) to PUB400's IP using the 4026 port as the target. So, from a network point of view, if there is no firewall, or if there is one which allows traffic over this port, I cannot see any issue.

I never have a problem with the customers where I access the IBM I via VPN.

Mit freundlichen Grüßen / Best regards

Thank you Marc for your help.

Yw, I often used this technique to check firewall issues.

I tried the SSH command from my workstation and it made a connection because I am seeing what you're seeing from netstat. An established entry from my workstation.

So the port is not blocked. Any other ideas?

I am not really used to use the debugger nor I have an access with enough authority to an IBM i system to be able to help you more.

However, here is what happens on PUB400 when I start the debugger from iACS SQL scripts like you do.

Job listening on 3825 port is QB5ROUTER in QUSRWRK subsystem.
Unfortunately I cannot see job log of this job.
Job handling the tcp session on port 3825 with my workstation is QTESDBGSVR in QUSRWRK subsystem. It is submitted by QPGMR/QTESDBGHUB which runs in QSYSWRK subsystem at the time I request to start debugger.
Unfornately I cannot see job log of this job.

Have you got those two QB5ROUTER and QTESDBGHUB jobs active? Maybe you could check their job log? I can't do it on PUB400.
