| I installed Windows MQ7 client (on a Win XP Prof SP 2) and MO71. I can ping the host. I see a runmqlsr running for the listener port. I can ssh onto the host from my Win XP Prof workstation. But a connection attempt in MO71 fails with 2538. Any ideas? |

Obvious questions, but I'll ask anyway: are the connection name details the same as for ssh? Is there a firewall active that may be blocking?

I'd give 2538 as an SSL mismatch...
Can you please supply
SSL setup of server connection channel
SSL setup of your client connection in MO71
Have fun

Please read the WMQ Clients doc (or InfoCenter equivalent).
Did you set the channel and ipaddress on the client to match exactlly the channel name and ipaddress of the host?

| Bruce, originally I had setup the hostname with dns, and then after receiving 2538 I changed it to IP. The port I got directly from ps -ef | grep runmqlsr - The channel name matches exactly to the results of runmqsc display channel (name) all |

For ssh I use Putty and successfully use the hostname or IP. The port for this is 22. Tne Putty ssh has no problem from my workstation and I can ping the host from the command line. Doesn't this rule out a firewall problem? |

For ssh, not necessarily as that port may well have been left open for obvious reasons. The fact that you can ICMP ping it though does suggest firewall is not the issue - but still worth asking your network people to check their logs.

Is the listener binding to a virtual IP - is this a HA cluster?
It suggests that what IP you ping, is not the one that the MQ listener is bound to.
Try a netstat -a on the host. |

MQJeff,
amqscnxc is not available in /bin - (this was MQ7 client MQC7 support pack installation). However, amqsgetc is available: the output:

H:\>amqsgetc TEST.QUEUE
Sample AMQSGET0 start
MQCONN ended with reason code 2538

fjb_saper,
I tried netstat -a but possess insufficient network guruhood for comprehension of the voluminous output. I tried netstat -s -s and got a much smaller display but I don't know what I'm looking for. What should I grep for?
To my knowledge, HA is not involved and VIPs are not in play. I assume that the netstat -a was meant to confirm this. |

OK guys, thank you very much for the help.
I finally did what I should have done initially. - I went to the firewall guy and confirmed that it is firewall protected - and that the firewall rules allow my workstation to ping and to ssh but nothing else. |
