Hello
i would like to know if is it possible to make a vb aplication that can perform curtain task on a unix machine.
these task would be character capturing after i give a unix command.
But the first problem: is how do i set up a telnet session in my vb program.
can anyone help me with this problem, or is there a sample program from vb that can peform task like that.
Please help me, i'm a newbie

Use the winsock control to connect to a telnet server on port 23.
I am having a similar problem, but I am trying to connect to a linux machine. I connect to port 23, and using telnet it pops up a message saying 'welcome, blah blah blah, don't do illegal stuff.' and prompts for a username/password.
What I get, in ASCII is "?8??C" or "ÿýÿý ÿý#ÿý'" depending on what type of variable I put the data from the Winsock.GetData() function into. (First is variant, second is string - I thing variant is the right one because as far as I know it is talking back in unicode and the variant type converts it to a 'proper' string for me.)
Any ideas?
Thanks,
Matt
You're connecting okay, you need to look up documentation on the telnet protocol (or someone might have a telnet with Winsock VB tutorial). I believe the way it works is that before you get the logon screen, the telnet server and telnet client negotiate standards, the type on screen, etc.
Not when I've done it...unless the winsock control did it for me... are you sure that you're using the getdata method of the control properly and that you're sticking it into an appropriate type of and size variable?
Post your code so we can do a little debugging of our own. :)
been there!
the telnet protocol is very complicated....
Someone sent this to me a while ago.
Its a terminal program written in VB and supports telnet.
once the telnet handshake is complete then the data starts flowing in what we would expect "clear text"
