Does anyone > know if this is possible? Sure is! Cisco sells serial cables that connect from their various console connectors to PC ports. That's a fairly standard configuration (if I recall correctly, if you buy the cable from Cisco it will be the same color (usually blue) as the label of the Cisco side. It would be the same cable no matter what OS you use, so you might find a local Cisco expert that connects to router consoles from a laptop using Hyperterm. Seach for "console cable" and your model number on www.cisco.com. They have a fairly complete listing. To test the cable, use the most simple software you can find. I recommend 'tip' in FreeBSD (which is configured by editing the /etc/remote file). Look for "cuaa0b" as an example and clone it. I usually create a config called "out" so I can literally "tip out" to get to the machine I'm working on. Anyway, once you get tip running, you can look into more interesting software. My favorite is conserver (http://www.conserver.com/). However, your question seemed to imply that you wanted a bi-directional connection. To do that, you'd need to configure each to have a login prompt, you'd need to set things up properly so that the two don't get into a battle (each system's prompt being interpreted as a login attempt from the other side). That doesn't sound fun, but it could be possible with a lot of testing. --tal -- Tom Limoncelli -- tal@lumeta.com -- www.lumeta.com http://www.EverythingSysadmin.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
