We have around 15 routers currently which we use a Cisco access server for console access. We are going to triple this number but the access servers are very expensive £1000's!! with only 16 ports. Can I use a unix box to provide the telnet access to the serial console ports on the routers?
If so what do I need for me to be able to do this. Ie. What hardware/software I need, web addresses for more info etc.
