Problem with RSA key

**NightEagle** · 11-06-2006

Hello, everyone.

I am experiencing a login problem to a remote computer using SSH and a pub key.

The RSA key, was generated under WinXP via the SecureCRT client. Recently, I have ported to the Suse 10.1 distro. The public key, is stored to the remoted computer I am trying to login.

I have installed the RSA key, to my linux with the ssh-copy-id script, and additionally I have copied the pub key, into my /home/user/.ssh folder.

When I am trying to login with ssh, I am being prompted for a password. The problem is that I was not using a pass under XP. When I am trying to login using the KSSH client from linux and specify as identity the RSA key, I am prompted for a passphrase (as I was under XP), but when I enter the passphrase, I receive an error and I am also prompted for a password.

Note that from another pc under XP, I can login as I used to with the same RSA key.

Any ideas would be helpful.

Thanks, in advance for your time.

It sounds like you generated an ssh key from a windows box and then copied that to a Linux box.

Is that right?

**NightEagle** · 11-07-2006

Yes, that is exactly what I did. I had no other choice, since the key was generated from Win about a year before.

To be honest, Number33 have absolutely no idea if that was right.

Do you have any ideas on how I will be able to port my key to linux?

Thanks, in advance.

I don't know if a SecureCRT key can be converted to an OpenSSH key.

Define the scenario of what you're trying to do and lets take it from scratch.

Lets take it from the scratch, Number33. Thanks for your interest.

What I am trying to do, is login to a remote server using SSH under linux, with a public key I had created under Win with the SecureCRT client.

I have just found a way, to convert the SecureCRT key, to openSSH key via the command,

Code:

ssh-keygen -i -f mysecurecrt.pub > myopenssh.pub

which is supported for For OpenSSH 2.9 and later (The server I am trying to login to, supports OpenSSH_3.8.1p1).

Now, when I login with the myopenssh.pub key, I receive the following error from verbose mode:

Code:

debug1: Trying private key: ~/.ssh/myopenssh.pub
debug1: PEM_read_PrivateKey failed
debug1: read PEM private key done: type <unknown>

Afterwards, I am prompted for a passphrase, and when I give the one I had, I am also receiving an error.

Do you have any ideas why the previous error happens?
