ssh implementation-------putty on client pc

[sheevm]

Hi!

I am implementing SSH on HP-UX running 11.0

I am using PUTTY to connect from my PC using SSH.

Will someone out there give some tip how to generate key in putty?

I was told that I need to generate key for each user in putty and transfer over to HP-UX boxes.

I appreciate your help.

Get putty keygen. Generate the key and put on hp-ux server. You need to put it in $HOME/.ssh/authorized_keys file.

The putty keygen works in similar fashion to the ssh keygen.

You do need the putty keygen executable though.

Anil,

Is putty keygen a different tool? If so how can I get it? is it free?

Thanks.

IT is free. Didn't you get where you got putty. Power of google. Search it.

[Rick Garland]

Hop on google. Do a search for 'download putty'

The 1st entry will will have the resources you need.

When you goto the putty download there is a option to download putty and download the zip file with all of the ssh utilities. Download the .zip file and the key generator will be one of the utilities.

good luck

Hi Folks,

I was side tracked for few days. I downloaded puttygen. It has two option "Generate Public Key" "Generate Private Key" Which one I should do? Also is there a specific client directory this file must reside?

Thanks.

You need to generate both a public and a private key. the public key will go to ~user/.ssh/authorized_keys on Your hp9000 system, and the private keys should be stored somewhere safe.
networked-user homedir is *not* safe, best option would be a smartcard or an usb-stick with read-only switch (available and cheap).

I am still having issues with this.

Steps I have done so far:

1. Generated public key using puttykeygen
2. FTPd to HP-UX SERVER /home/murthy/.ssh/authorized_keys/rajikey
3. Generated private key using puttykeygen and saved into a filename in my PC

4. In puttyclinet SSH-AUTH I am trying to assign private key file. It does not take it.

I am following PUTTY documentation:
------------------------------

4.20.5 â Private key file for authenticationâ
This box is where you enter the name of your private key file if you are using public key authentication. See chapter 8 for information about public key authentication in SSH.
This key must be in PuTTY's native format (*.PPK). If you have a private key in another format that you want to use with PuTTY, see section 8.2.12.
----------------------------
In this window in PUTTY It asks for a private key . But It only has two buttons "Open" "Cancel" I assume Open is the button saves the file authentication. But it just beeps and does not work.
--------------------------------------------------------------------------------------------------------
The work I have done at the server side is:
I FTP'd the public key I generated from PUTYKEYGEN to /home/murthy/.ssh/authorized_keys/rajikey

SSHD-_CONFIG file in HP server. (I am not sure if I need to do anything here)
