System::Connections seems to be gone from the SDK

 

DevCentral seems to document the iControl connection table interface System::Connections. Though I looked through both the v9.6 and the v10 SDKs, and I can't see the WSDL files for System::Connections in there.

 

 

http://devcentral.f5.com/wiki/default.aspx/iControl/System__Connections.html

 

 

 

I did download and install pyControl, and I noted that it did contain the System.Connections.wsdl file. I was able to show and delete connection table entries from a 9.4.7 LTM using pyControl.

 

 

 

I'm pretty new to all of this, but I'd imagine you could just take the WSDL file out from pyControl and use it as if it came with the regular SDK. Am I wrong?

 

 

 

If anyone has a hint on why this was removed or if this is coming back, I'd be interested to know.

    I suppose the post below answers my secondary question:

     

    http://devcentral.f5.com/Default.aspx?tabid=53&forumid=1&postid=63136&view=topic

     

     

    "Unfortunately access to the connection table was removed in iControl due to performance issues with accessing that large of a data set within a HTTP SOAP request. So, at this point, there is not an equivalent in the iControl API to remove individual entries in the connection table."

    You are correct. The service endpoints are still in there for deprecation purposes but haven't been maintained since before 9.0 so they are definitely a "use at your own risk" interface at this point.

    This does not solve our problem.

     

     

    How to break active persistent connections from a VIP when you session disable and down pool members and nodes.

    mariogolf ,

     

    Can't you use iControl to force-offline a poolmember, and then use (with caution, see Joe's note) the delete_active_connection method in System::Connections to clear out any currently-active connections to a Vip or to a poolmember?

    Anthony thanks for the post. Looking into pyContol running in a Linux environment. Would VERY much appreciate a roughed out version of this solution.

    I'm no expert, but I got pyControl running on Linux.

     

     

    It seems that python version 2.5 is preferred.

     

     

    How far along are you?

     

    -- Is python installed?

     

    -- Did you install ZSI-2.1 yet:

     

    http://sourceforge.net/projects/pywebsvcs/files/

     

    -- is iPython installed?

     

     

     

    While I was able to delete a single connection using the System::Connections methods, I'm still not sure on the python syntax to specify deleting all conns to a particular vip, or all conns to a particular poolmember. I think I'm leaning towards just running bigpipe commands over ssh:

     

     

    ssh root@my.bigip.com "b conn server 10.254.1.22:389 delete"

     

     

    This works well for me at the moment!:D
