ssh and private keys

Hi!

I have a simple question.
How do I use private keys for connecting to my shell account in "ssh"
command?
I have a private key generated by Putty on Windows and I have to put
it in Connection/SSH/Auth/Private Key File for Authentication in order
to be able to connect to my server.
How do I achieve the same in Linux?
Should I use some other software than "ssh"?

Thx,
mat

You need to sftp (using name/passwd one time) to upload your PUBLIC key into
the server's .ssh (if it's Linux, it's ~/.ssh) directory.

Upload your puttygen generated authorized_keys.txt file to Linux and
append it to your authorized_keys file there:

cat authorized_keys.txt >> ~/.ssh/authorized_keys

That works for me to connect Putty with my passphrase to Solaris, NetBSD
and multiple Linux versions.

But to connect Linux ssh to a Unix/Linux box you would have to generate a
key in Linux (which can use the same passphrase) and append its public key
(that filename may vary depending upon type of key) to authorized_keys
file at destination.

I do not know if a Putty generated identity.txt would work for ssh
identity file (never tried it).

See the man pages for ssh-keygen(1), ssh-copy-id(1), and optionally
ssh-agent(1) and ssh-add(1). It's possible to use your putty secret key,
too; I think ssh-keygen will convert from that format.

No.
