The next step is to create a key pair for authentication. There are two possible ways to create keys. The first is to create the keys with PuTTYgen on the client, upload the public key to your server and use the private key with PuTTY. The other is to create the key pair with the OpenSSH tool ssh-keygen, download the private key to your client and convert the private key to a PuTTY-style private key.
Login to the server as root
or
svnuser
and type:
ssh-keygen -b 1024 -t dsa -N passphrase -f keyfile
substituting a real pass-phrase (which only you know) and key file. We just created a SSH2 DSA key with 1024 bit key-phrase. If you type
ls -l keyfile*
you will see two files, keyfile
and
keyfile.pub
. As you might guess, the
.pub
file is the public key file, the
other is the private one.
Append the public key to those in the .ssh
folder within the svnuser
home directory:
cat keyfile.pub >> /home/svnuser/.ssh/authorized_keys
In order to use the private key we generated, we have to
convert it to a putty format. This is because the private
key file format is not specified by a standards body.
After you download the private key file to your client PC,
start PuTTYgen and use
keyfile
which you got
from the server the passphrase you used when creating the key.
Finally click on and
save the file as keyfile.PPK
.
