Hi PerlMonks, i have a requirement where i need to connect to 900 routers using telnet and execute certain commands and capture the output. I am using Net::Telnet module to achieve my requirement. But i have a problem managing the router login prompt. It is impossible for me to know the login prompt of 900 routers. Is it possible for me to use regular expressions in Net::Telnet module to manage login prompts or anyother way to use regular expressions in login prompts...........please advice
