Connecting to remote Unix box using VB

Mallya, Deepak non Unisys
Guys -

Does anyone have an idea as to how I would be able to connect to a remote
Unix Solaris (and also IBM OS390 MVS) box, execute some scripts (JCL on
OS390) using VB com or .net component and the results back to my VB
Application.

Please let me know of any ideas or thoughts that you may have.
Code examples or technical articles on net will be extremely helpful as I am
a novice.

Thanks and expecting some ideas.

Regards
Deepak

Deepak,

I know that there are some telnet components out there like IPWorks from
www.nsoftware.com ; another approach might be to use either the command
stored proc in SQL Server or a telnet from a command-line COM object like
one of these: http://aspdll.com/category.asp?id=15 .

A more .NET-oriented way would be to write your own object with the
System.Net.Sockets namespace (some introductory material at
http://www.aspalliance.com/chrisg/default.asp?article=92 , or to use
/nsoftware's new IPWorks.NET, which you can find at
http://www.nsoftware.com/products.asp?part=IPN5-A . I'm not sure of the
licensing fee for this one, but there's a Trial and Full version; you can
get more information from the vendor.

Hope this helps...

Peter

How do I something like this :

The Rshell component is used to execute commands on a remote Unix machine
using the rshell mechanism.
The Rexec component is used to execute commands on a remote UNIX machine
using the rexec mechanism.

Please suggest.

The Code that I managed to put till now looks like this.

Dim Telnet As TcpClient = New TcpClient()
Telnet.Connect("mc", 23)
Dim TelnetStream As NetworkStream = Telnet.GetStream()

If TelnetStream.CanRead And TelnetStream.CanWrite Then
MsgBox("Read and Write")
' Does a simple write.
Dim sendBytes As [Byte]() = Encoding.ASCII.GetBytes("Is anybody
there")
TelnetStream.Write(sendBytes, 0, sendBytes.Length)

' Reads the NetworkStream into a byte buffer.
Dim bytes(Telnet.ReceiveBufferSize) As Byte
TelnetStream.Read(bytes, 0, CInt(Telnet.ReceiveBufferSize))

' Returns the data received from the host to the console.
Dim returndata As String = Encoding.ASCII.GetString(bytes)
MsgBox(("This is what the host returned to you: " + returndata))

End If
If TelnetStream.CanWrite Then
MsgBox("Write")
End If
If TelnetStream.CanRead Then
MsgBox("Read")
End If
Telnet.Close()

Regards
Deepak

Does this code work? I'm behind a firewall without an available telnet
server.

Assuming your telnet stream can write, you would just send the commands
you want, and read the resulting output from the stream. I'm not much of a
Unix buff -- and it's not really on topic here -- so you'd probably have to
get command information from your system's man pages or another list.

If it's a telnet component you're looking for, you could try:

http://www.whisperstream.com/software/commlib/

I dunno if they have any other components, but the telnet one they have is okay and seems to be free and not expire (always a bonus).
