MQRC 2538, not 2358.

Same box as in connection from the same host as the QM runs on - works fine in client mode.

CHLAUTH rules in place, but still fails even if I disable CHLAUTH.


try this command and see,if it works:

ALTER QMGR CHLAUTH(DISABLED) CONNAUTH(' ')
REFRESH SECURITY TYPE(CONNAUTH)


even I had some authentication error issue, though the client and MQ manager were on the same linux machine.It worked with the above commands.

No, it was in fact the software firewall that comes with some versions of Linux.

Once that was stopped, things went back to normal.

You would do better to recommend THIS rather than suggest opening up queue managers to every man and his dog...
