Hello, i got a problem with telnet! I've been trying to use it, i'm kinda new around here. nut eberytime i open telnet.exe en watch my status, is says: not connected! How do i connect? Maybe the question is kinda dumb, but he, im new around here!
Please give me hints and/or tips.
Thanks
you have to provide the address to which u want to connect to and the port address(optional).
On the command prompt , type "telnet hostname.com xx" Replace hostname.com by the site u want to connect to and xx by the port no. If u don't specify a port no., it connects at 23 the telnet port automatically.
Don't forget that you have to have either a telnet server listening or you must telnet to a port that accepts connections from a telnet client. From what I understand, you can also telnet to an smtp server, although I have not tested this as of yet.
Edit: You might want to try a search of the forums on this from the homepage. There have been many questions on telnet lately.

The to post's above this are correct you need to provide a client for telnet to connect to
try telneting here cyberspace.org this will give you access to a free UNIX shell you will need to sign up for a shell follow the instructions the shell give's you if you telnet to it.
t2k2 you are absouletlt correct you can telnet to an SMTP server on port 25 you would do this
from windows like this start>run>telnet and this would prduce a telnet screen and you give the command telnet "the server address goes here" 25 or in linux you would type from a shell
telnet and you will get a promt that looks like this
telnet>
then from ths prompt type open and you should see something like this
(to) this is where you type the server name you want to connect like for example
(to)my-server.org 25 and it will say something like trying (servers address)
then
Escape character is '^]'.
ande it would greet you with a login prompt.
How ever if you telnet to an SMTP server you will get the Escape character is '^]'.
promt then the sendmail version called a daemon banner this looks some thing like this
ESMTP Sendmail 8.11.6/8.11
this tell's you the version of the sendmail daemon that is running on port 25 if you want
to send email from the sendmail daemon running on port 25 you would type
MAIL FROM:<email adress goes here>
you should see some thing like the sender is ok
RCPT TO:<person you're sending the email the address goes here>
you will recive a messege like receiptent ok
DATA
this tells the server that you are wanting to insert data to an email
after you have finished writing the email put a period or dot"." on the last line of the email
this tells the server that you have finished writing the email and are ready to send after that you should see a message like
message delivered

Thanks D.O.C. Do you know of any telnet client that echos the text you type. It does not do this on the client included with Windows 2k apparently - or at least, I don't know how to do it.
Thanks.

Although I use SSH instead of Telnet these days (most do, to my knowledge) Telnet can also connect to an ftp port, http port, and most basic ones that are widely used. Also, you should look for Putty, a popular telnet/ssh client that has a great interface and works like a charm for me. Just my personal recommendation.
t2k2 what do you mean by "echo" do you mean if you connect to a remote host and you typeQuote:

a number or letter it will repeat (eg) if i type "1" it will come up in the terminal like "11"
or do you mean something entirely diffrent ?
and here's the download page for PuTTY which as spyder32 said is a really good ssh and telnet client you should look in to it if you're on WIN

By echoing he means you type 1 and when recieved, the host your connected to will reply the 1, you can turn this off, the "new" telnet in win2k or winxp is like command line but the old one (9x etc.) was a crappy program like notepad
it's true you can telnet to any port you want, you can even telnet to SSH port, you can telnet to IRC
telnet irc.stealth.net 6667

With w2k you can start the telent service and telnet to the localhost -I always disable it on my system but it might be useful for remote admin of console based tools -ie certain version of mq series.

Hey canyou connect to every port with telnet? or is like 23 and some others. Just wondering?
Couple of corrections here.
1. Telnet was never a Windows thing it was a Unix thing M$ licensed it not unlike most the basic TCP/IP protocol stacks are based (read some history of TCP/IP). M$ did not invent networks. They came from research labs andd Universities :)
2. Why telnet to an FTP site? FTP (File Transfer Protocol) is set to do just that transfer files. One uses the put and get command at the prompt or highlight the file and click the right arrow in Windows. You guessed it M$ did not invent this either but license it again.
3. Connecting to a host, true you can telnet to any addy on any port as long as they allow telnet on that port. If they do not then your in their records another hole closed up long ago through firewalls one can allow HTTP on port 80, FTP on port 21 etc if those ports telnet is not allowed your IP is in the log. If you do get to these ports using telnet or FTP you will be asked to login most cases you fail 3 times your in a log.
4. If you need an echo to keep track of things then you have much work to do. Most of this stuff can be stored in say notepad line per line and you have but to cut and paste it in windows keeping track only of what line you just used. But true command line telnet prompts are from memory. This inside a DOS shell in Win it's best attempt at Unix prompts :)
Just be aware that firewalls have logs and you spend to much time you will be watched real time and I'd hate to go up against many people my age that watch this stuff. Also consider your quest to learn makes lots of noise on networks so everything you do that is learning real time makes it hard for Net Admin to find the real threats real time.
Peace
As a matter of fact, W2K's telnet can do that, t2k2. But don't worry, most people I know are also not aware of this ;). The key thing is to run telnet without any parameters. Then on the telnet prompt,Quote:

type "set local_echo" to set local echo
type "display" to display operating parameters
type "open host.domain port" to connect to host.domain at specified port (default 23)
type "help" to get help information
Peace always,
