connecting to a port wth telnet

akyy — Mon, 21 Dec 2009 13:34:52 GMT

I am trying following command:

telnet 10000

With SecureCRT it works, i can query my scripts.

But when I try with command prompt, it disconnects when I write a simple letter. Is a there setting in Command Prompt which I need to modify?

Hi

You telnet ip 10000, just like above, it will say connected. That's it. It's just a test for a port being open.

ndmp 10000/tcp Network Data Management Protocol
ndmp 10000/udp Network Data Management Protocol

10000 is for Netapps.

What exactly is listening on port 10000?

It's a specific software, a north-bound interface, importing and exporting reports to the main software from external OS.

To import or export, i need to execute scripts when connected with telnet.

SecureCRT works but command prompt disconnect when entering a single letter.

So the next question could be what SecureCRT does here - SSH?

SecureCRT also does telnet, not SSH , same as Command Prompt.

If you're talking about SecureCRT from VanDyke software, it does ssh and telenet and is is terminal emulator...and its a client installed on Windows.

I would not expect to be able to "telnet someserver 10000" and be able to run UNIX scripts, but be aware that it also has its own scripting language. I'd assume at that point, it makes the connection and starts whatever authentication process it goes thru.

I'd assume you need to do ssh to run remote commands, or some sort of remsh / rexec. I'd consult the docs for SecureCRT or contact their tech support.

Having never actually used it, and not knowing which "scripting" you're referring to, I can't go any further......

So, as I understand this, the built-in Telnet
client program on Windows doesn't behave the
same as a third-party Telnet client program
on Windows, and you're asking why in an HP-UX
forum? Why?

Well, hardly, but you do need to know what to
send to the server program, and you need to
have a program which can send it. (For
example, Telnet to port 80 on a system
running a Web server, and send it:
GET / HTTP/1.0
and a couple of new-lines.
http://www.dgate.org/~brg/bvtelnet80/
)

That didn't tell _me_ anything useful.

If the problem really is with the Windows
Telnet client, then you might get better
answers sooner in an appropriate (Microsoft)
forum. (Certainly better than "It's just a
test [...]".)
