Running Telnet through VB

[lilgirl]

Hi,

 

Is there a particular vb.net class that would allow me to run a program using telnet to log into the particular server i want to access without making the user deal with telnet? Basically, I want a button on a vb form that when clicked, runs a program that is stored on a server you can access through telnet.

 

Thanks.

If you want to connect to a remote telnet server you should have a look under System.Net.Sockets.

The TCPClient class will allow you to open a connection to the telnet server and obtain a stream. You can then send / receive data quite easily.

What language would you be coding in?

Im trying somthing similiar I think.

 

See if this is any help

 

This will connect to a machine and read the inital text sent back, and store it in a log file

 

Imports System.Net.Sockets

Imports System.Net

Imports System.Text

 

 

Module Module1

 

Sub Main()

Dim tcpClient1 As New TcpClient()

Dim NS As NetworkStream

Dim bytes(tcpClient1.ReceiveBufferSize) As Byte

Dim hostaddr1 As IPAddress = IPAddress.Parse("127.0.0.1")

Dim MyEndPoint1 As New IPEndPoint(hostaddr1, 23)

Dim buffsize As Integer

Dim buff2 As String

FileOpen(1, "C:\logfile.txt", OpenMode.Output)

tcpClient1.Connect(MyEndPoint1)

NS = tcpClient1.GetStream

ReDim bytes(tcpClient1.ReceiveBufferSize)

buffsize = CInt(tcpClient1.ReceiveBufferSize)

If NS.DataAvailable Then

NS.Read(bytes, 0, buffsize)

buff2 = Encoding.ASCII.GetString(bytes)

Print(1, buff2)

End If

FileClose(1)

End Sub

End Module
