i'm a bit new at this, mind, and i only want some basic information. i have read the texts and a LOT of them seem extremely outdated. here's an example: it seems that port 80 is no longer in use for http type stuff. another thing i am having problems with is this: the only port which is getting me anywhere at the moment is 21, the standard 2(2/3, i forget) seems void. what does this mean?

thank you for your help in advance. hey, you don't even have to answer me, but if you could point me to some new or updated text files, i would appreciate it . . .

Isn't the telnet port 23?

yeah standard port is 23. whatever, i can't seem to connect to ANYTHING via that port. i'm presuming that either i'm doing something terribly wrong, or something i'm missing...?

Firewall? Or maybe they have rlogin disabled on their computer. Where are you trying to get in?

Most servers dont generally run open telnet servers anymore. De facto standards say that telnet servers should run on port 23.

And yes, port 80 is still most often used for http. 8080 is also used, but not as much. Port 80 is also the de facto standard for HTTP (web) servers.

yeah, well that explains a lot. i'm not trying to get into anywhere in general. at the moment, since i'm new at this, i'm just poking around and doing random things just to understand how this all works.

are there any new<ish> texts about telnet? all i've managed to find so far is stuff from the 80's/early 90's. this stuff is interesting, but most of it is no longer valid (bah, just like with phreaking)...

also, here's another thing i can't quite work out. i portscan and attempt to telnet into those open ports. can't connect. why? am i just a fucking moron? maybe.

You do know how to specify which port to telnet to correct? Not all services with send stuff back to you if you open a telnet session...

Telnet is an old technology, but think of it more as a general character terminal program. Telnet can be used in situations where you need to connect to a TCP/UDP port and exchange CHARACTER data such as FTP (for port 21 command mode. FTP uses port 22 for data transfer and it only INITIATED from telnet, the data is not sent over the port 21 connection to the FTP server. A new TCP connection is created using port 22 on the server and a randomly assigned port above 1024 on the client).

telent is still used alot for unix winVNC implementations. you may want to look into its uses in initiating a win VNC server on a unix box to better understand it.

BTW, look up SSH it is more or less the replacement ofr telnet

I don't think he needs the encryption SSH provides (can it even connect to anything besides the SSH daemon?) - from what I understood he just needs something to connect to various remote services

Try this:
telnet drill.hackerslab.org
login level0
password guest

Check http://www.hackerslab.org/eorg/
Its a test/challenge sorta thing that teaches what you seem to be lookin for.. if you're interested in linux/unix also and have some spare time.

how about this:
could you make a batch file so that it connected through telnet or ftp to a renote box and then (if there were no/bad permissions) run commands on that box? and if so how would those commands go?
