Hello there ...

I defined a SVRCONN channel for java client access... Distant access...
But, developpers start a lot of transactions to test some add and/or some new application features.

The problem is that my SVRCONN channel is defined on a major Queue Manager which hosts WBI and more. So my question is : do I set something, somewhere to restrict the number of CLIENT Connection only?

Because in QM.INI if I restrict access through number of channel started it includes ... every channel ( CLSDR - CLRCVR ... and of course SVRCONN ).

Any clue ?

Thx,

add a security exit like blockip or set SSL on the svrconn channel.
Your developers will be locked out.

see http://www.mqseries.net/phpBB2/viewtopic.php?t=31740&highlight=security+exit+blockip
or check out Capitalware's security offering...

Enjoy

Ouhaou ... Only a third program to do this ? I heard that Blockip is able to restrict number of connection of an IP such as 10.75.* right ? I'll check some test.

Thanks,

Edit : I test this version with a MQ 5.3 ... does this exit exists under MQ 6 ? ? ?

Well I defined everything with Blockip and it works very well
Very good option is MAXCHL

By the way it shows me that the Dev Connector works through MQSeries with a BlankUser !!! Damned !

I'll ask them some modifications .

a blank user....

You can specify in the parms for BlockIP2 that it will not accept that incl. the special user (using -n) in SCYDATA...

SCYEXIT('BlockIP2(BlockExit)') SCYDATA('10.31.10.12;-n;')

or if you're using a configuration file:
BlockMqmUsers=Y;
# Flag to block for system accounts like: mqm, musr_mqadmin and ''

There is a lot of posibilities.

-- Lock it or Lose it --
