Martin sent me an email about packet capture tool for IOU that he wrote. I haven’t tested it because I’m short on time right now so let me know what your experiences are:
Some of you might already know IOU, it’s Cisco IOS compiled on Unix. It allows emulating routers and switches.
One IOU process is one device. Communication between devices occurs through netio sockets, located in /tmp. Until now there wasn’t any tool for sniffing on these connections. Now there is one.
