Telnet scripts

[ManagerJay]

I am trying to develop a telnet script that will allow me to make changes to router configurations at a specified time. Since each site has a server physically on site, my thinking was developing a telnet script to make the necessary changes would make sense.

The routers I need to change the configuration on are CISCO with varying IOS levels.

I have tried using a .telnetrc file without any success. Any suggestions anyone can offer would be greatly appreciated.

TIA,



Jay

Use Expect. See

Yes, Expect is a popular choice for this type of automation.

Setting the routers up to allow remote commands (rsh) is also a possibility (I don't remember exactly how to do this, but I know I did it a few years ago on a Cisco 7200, running IOS < 12). This option should be used carefully as it has the ability to present significant security issues if not used properly.

Thanks for all the help. After looking at Expect, and seeing some projects on the future this will be useful for, I'm going to give it a try.

Thanks again for all your help.
