After the ciphers problem , I face some problems in authenticating with the use of public key. I used ssh-keygen -t rsa to create my own rsa public and private keys. Then, I editted the value of PublicKeyAuthentication so as it becomes yes in ssh_config file. I also copied public key mykey.pub to server and added it to authorized_keys (cat mykey.pub >> authorized_keys).

But, for my dissapointment, ssh denies to accept my prays ... Could you help me ? Any propositions? I have searched all the Internet till now but I didnt find a positive solution.

Hello everyone, I'm new to the forum and I'm looking for some information about a security problem I found. Can anyone help me?

It might be the key format problem, try to vi the authorized_keys files and make it much more like the decent style...

I met these kinds of problems before...when I appended my putty-generated pub-key into the file....when I appended my Debian-generated pub0key into redhat....etc.

I'm not pretty sure, anyway you may try...

I still have problems... I generated a new pair of keys with the name thauma kai thauma.pub. You can see above the log messages I get through ssh -vvv -i thauma username@server. Any propositions??

What ssh protocol are you using 1 or 2?

I believe that the only key types allowed in ssh1 is rsa1 where as ssh2 allows rsa and dsa keys.

EDIT: nvm i read more of the man pages, rsa1 and rsa are the same thing. Ignore the man behind the curtain.

You also need to copy the private key to your ~/.ssh directory and call it id_rsa, possibly the public key as well (although I can't quickly think of a reason why the public key would be needed there).
