telnet is not particularly scriptable; you might prefer to use nc (aka netcat) instead, which handles non-terminal input and signals better. Also, unlike telnet, nc actually allows SSL (and so https instead of http traffic -- you need port 443 instead of port 80 then). There is a difference between HTTP 1.0 and 1.1. DoS Attack. Another type of Telnet attack is the DoS – denial of service attack. DoS attacks in general is simply a way to disrupt the communication of two network devices by using all the bandwidth that they connection has to offer.
