If you are using Windows 7/Vista, u need to enable telnet client on add/remove windows features.

Re: not able to telnet to HPUX

The Windows domain administrator may have applied a security policy to the Windows Firewall (or any other software firewall product on your workstations) that stops telnet.exe from making network connections. If this is true, your site apparently has a policy to stop using telnet and switch to secure login methods (like SSH) instead, so you should install SSH and disallow telnet connections on your HP-UX servers too.


Telnet is an obsolete protocol. It is not secure: if someone can monitor your network traffic, he can capture your entire telnet session, including your passwords and anything else you may see or type.

Maybe telnet service is even disabled on the server. If you already have putty, then try ssh connection.

Hope this helps!

Start with small tests


- Do Telnet from putty

- Do telnet from other HPUX server


If you can do it and you can't from your windows it must be a firewall issue or a group policy.
