ACS - Reached maximum number of administrative connections

When trying to login to ACS (3.1) I had a message stating that the maximum number of administrative connections had been reached. Eventually I had to reboot the server to fix this, doing a netstat on the W2K server revealed quite a few connections to port 2002. How can I forceably clear these connections down? There must be a utility that enables you to disconnect a specific TCP/UDP port?

Thanks

Re: ACS - Reached maximum number of administrative connections

Hi Steve,

The only option I can think from ACS perspective is t o stop the csadmin service.

net stop csadmin

Then give around 1 min to timeout the dangling connection and then restart the services-

net start csadmin

Also, not sure why you have so much dangling connections build up? what vesrion of code are you running? Did you apply the vulneribility patch described below:

Re: ACS - Reached maximum number of administrative connections

Thanks Mynul,

I did stop and restart the csadmin service but only for 5 to 10 seconds.......

What's the best way of being informed of patches/bugs in ACS? Is the quickest way just to keep an eye on http://www.cisco.com/pcgi-bin/tablebuild.pl/cs-acs-win and look out for new patches?

Thanks

Steve

Re: ACS - Reached maximum number of administrative connections

Steve,

You may also think of incorporating some control as to who can access this ACS box using the Access Policy feature documented here

Thanks,
