I'm looking for a way to automate the setup of a telnet session to a
number of hosts.

What I would like is the ability to open the default telnet application
to a certain host and wait for the various prompts and reply with some
commands.

After that the user of the application should work with the telnet
session.

I can open a telnet session from a vb script but I would like to know if
it is possible to use some methods or properties to manipulate the
session afterwards.

If anyone has a sample or some info on how to manipulate a sesqion I
would greatly appreciate

Best regards,

Papa

Alternatively, you can do one of 3 things:

(1) Buy a telnet ActiveX control (none of which I have seen that I've liked, so I can't recommend any - Dart, Mabry, and at least
2-3 other places make them.  Those can be automated from VBScript.

(2) Write your own (I keep hoping someone will).

(3) Use a scripted Telnet client.  There are several which are commercially available; the 2 which I use consistently are TeraTerm
Pro and IVT Telnet.
http://hp.vector.co.jp/authors/VA002416/teraterm.html is the home page for TeraTerm; it is open and easy to use, but is beginning to
age.
http://home.planet.nl/~ruurdb/IVT.HTM IVT telnet is alive and kicking and has just gone "semi-commercial" - if you don't need
Kerberos support, you can get it for free also.

My problem is that I don't have the right to install software on the
clients.

I use CRT from VanDyke Software, Inc and everything is possible from
there but my customers have
"standard" W2K pc's.

So they only have the dos telnet.

Could it be possible to force the telnet to write via stout only?

Regards,

Papa

That's why I use TeraTerm.  If you can play with the restrictions at all, neither TeraTerm nor IVT truly needs to be "installed";
they can be extracted as files and run remotely even - still problematic for a very careful LAN.

There's nothing much that can do it raw.  If you want to dig a bit, here's a link to the discussions on scripting telnet archived in
Google.  Watch out for wrapping URL -

Anywho, I have also written a telnet app for Windows using VB but haven't
seen or used it in awhile, but I have done it therefore I know it can be
done.  If you guys need help with writing another, or even simply creating
one that will be used
in scripting, let me know and I will do my best to start you on the right
path :)

The thing about what I want is that it's fairly simple - I send text out, I want text back.  I don't care if I can never see
anything GUI at all - which simplifies everything except for the server side.  Even *that* should be simpler because it just needs
to be told "I'll take the lowest-tech terminfo you have".

I would almost think this could be done somehow via a kludge with ADO or XMLHTTP....

: Well, personally, I use SecureCRT from VanDyke Software :P

I think I've just been avoiding getting eyeball-to-eyeball with sockets..

(Unless I would write a complete telnet application in the script)

But do share your knowledge anyway.

In it's most primitive form its works like this.
But it's not nice to use sleep rather than wait for something from the
host as this makes it impossible to react to errors.

If its not possible to capture from telnet is it the possible to read
from the console screen ?

Dim  Shell
Set Shell   = CreateObject("WScript.Shell")
output = Shell.Run("telnet 172.20.1.1")
wscript.sleep(2000)
Shell.Sendkeys "password1" & VBCrLf
wscript.sleep(500)
Shell.Sendkeys "enable"  & VBCrLf
wscript.sleep(500)
Shell.Sendkeys "password2" & VBCrLf
Wscript.sleep(500)
Shell.Sendkeys "Command1" & VBCrLf

Regards,

Papa

: I'm not aware of the possibilities of using the winsock control from
: vbscript but I'm pretty sure it won't allow me to leave the script and
: 'hand over' the session to the user who is supposed to continue.

========================================
PROJECT: ActiveX (DLL?) TO RETURN PORT DATA
========================================
Goal: a lightweight control which  is nothing more than a wrapper around a TCP component which exposes a single method - "probe",
which sends a basic ping or query to a specific port on a specific IP address, and has a specified timeout. there should be 3
standard error levels - 1 for no response, another for a refused connection, and of course 0 if "something" was returned.  There
should also be provision for exposing data returned (via a property, or would this more appropriately be a return from the method?).

I suspect there are 50 components out there which will do this and are free, but it sounds like it would be a simple enough thing
for someone with minimal VB background to undertake..
