Post subject: Running CCP on Parallels VM against GNS3 routers |

Posts: 32 | Hey all, I'm currently studying for the CCNA-Security exam. I have a Parallels Win 7 VM running on my Mac that I wanted to use to run Cisco Configuration Professional against routers in GNS3 running on the same Mac. So I dragged out a 'Host' icon and configured the Generic Ethernet NIO to be 'vnic0' which was the vnic associated with the VM. This happily worked, and I can reach the routers from my Win 7 VM. But, after I start up CCP and discover a router, and then try to do any configuration on the router, CCP dies with an error message stating, 'An internal error has occurred. Cisco CP will shutdown. Restart Cisco CP and discover the devices again.' I did a Wireshark capture against the router interface that the VM was doing the http against, and I do see CCP making calls against the router and the router returning answers, like so: (CCP PC)

Anyone seen a problem like this before? I'm running CCP with Java 6u11, which is supposedly the supported Java version. Wonder if it's a problem with running CCP against a GNS3 router, or if it's just a general CCP/Java problem??

Posts: 32 | OK, fixed it... Read in CCP release notes that app must either be installed by PC administrator (which it wasn't, since at that point I didn't know it had to be) or if not, the app must be run under administrator context (right-click, choose 'Run as Administrator'.) Doing the second option (running as administrator) works. Happy that I can can do my CCNA-Sec studies all within the context of my laptop :)
