im just beginning to learn how to hack. i have learned how to use MS-DOS and how to ping websites and other computers, but when i try to telnet ip addresses, it brings up telnet, then sayed "connection is lost" so...idk
you have to specify port as well as the host, by default port 23 is triggered which is usually off. e.g telnet forums.digitalpoint.com 80
With telnet you need to provide user/password. If you're accessing to your site is preferable to use ssh because data transfers encrypted.
different ports serve different purposes. For example you can telnet to port 25 (for smtp) purposes than you can email Port 21 for ftp port 80 for web port 110 for pop and alot more ports, do some google for port lists.
ok. thanks, and i more thing, is there like, a cheatsheat for commands on telnet? i forget what they are.
try telnet /? Goodluck BTW, this forum is for webdevelopers not for supporting hacking related activities, if you are here for learning how to hack, I guess you are at wrong place..
