Re: Cal you telnet to an IBMi host on ports that you think you will be using for MQ and Connect DIrect if the host doesn't have the services running?

Thanks to all who replied. Did some digging around using netstat *CNN and
listed all ports. Found nobody was listening on 1414 but there was a job
listening on 1364. So I've gone back to the devs and asked if somebody can
look at the MQ configuration and perhaps start the queue manager if it's
not running. Totally out of my area but that seemed like a reasonable
assumption.

The NETSTAT *CNN is a good idea to see what ports are being served.
F14=Display port numbers

An alternative might be to look at the services related to this. Like
select AUTHORIZATION_NAME, JOB_NAME, LOCAL_PORT, REMOTE_PORT,
REMOTE_ADDRESS, LOCAL_ADDRESS
from qsys2.netstat_job_info
;

Situation. New servers that will support MQ and CD. MQ is setup but not
sure about CD yet,

Teams want to make sure firewalls are working so that MQ traffic is passing
through on port 1414 (it's coming from a z/OS host) and CD from a Windows
server on port 1364.

So they run the telnet command (telnet <host name> <port>) and see if they
get a response.

From z/OS a telnet to host on port 1414 gets a connection rejected. I can
see in the firewall logs that packets are getting through but I am not sure
if the MQ Manager is running or listening on that port and I don't have the
IBMi knowledge to find out. Unfortunately our tech resources in IBMi are a
bit thin on the ground at the moment as we transition to a new service
provider so we are flying in the dark a bit.

Similarly a telnet to the same host on 1364 gets the same timeout. Again
packets are going through the firewalls but I don't think the CD server is
running. I am no expert here but I would have thought you need the MQ Queue
Manager to be running for packets to be acknowledged and similarly for the
Connect DIrect server to be running. I don't think telnet on that port
would prove anything.

I did try a command dspmq but I received an error about something not found
in *LIB (I was using qsecofr :-) ) so people say to me that the MQ library
has not been added to the list of libraries that this account needs to see.

Any hints on what to do appreciated. Thanks
