OK, now the issues that I found today: first there are several key generation algorithms: rsa, dsa, ecdsa and ed25519 and there are many releases of OpenSSH (you can have one version on your local machine and an old version on your server): In the best of cases, this will allow connect to your server without a password. To achieve this, you can use the ssh-copy-id utility, or you can do it manually using the cat and scp commands. You need to move your public key to file. On the local machine you also need to create the private/public keys with the ssh-keygen utility. If it doesn't exist, you can create it manually with a mkdir command and then to assign the correct permissions with chmod, or otherwise you could use the same utility, ssh-keygen, to create private/public keys, but on the server for your user. On the server, validate if your home folder has the. The basic process to allow authentication without a password is as follows: I have had the same issues since before, but today I had to set up one new server. SSH tunnel to access a MySQL (bind = 127.0.0.1) server Ensure ownership and group ownership of all non-root home directories are appropriate. ssh/authorized_keys file.ĥ Set permissions on the target machine chmod 755 ~/.sshĦ. This tells ssh to accept file authorized_keys and look in the user home directory for the key_name sting written in the. Modify file /etc/ssh/sshd_config to have RSAAuthentication yesĪuthorizedKeysFile %h/.ssh/authorized_keys If ssh is not listening on the default port 22, you must use ssh -p port_nr.Ĥ. To Enter passphrase: when you've created keys (so it's normal). If the server still asks for a password then you gave something. You need to do ssh -i path/to/key_name ssh -v. Ssh-copy-id -i path/to/key_name.pub Logging ssh will work only for the default id_rsa file, so here is the second trap. Transfer the your_key.pub file to the target machine, ssh-copy-id you didn't create a default key, this is the first step to go wrong Here pressing just Enter, you get default two files, " id_rsa" and " id_rsa.pub", in ~/.ssh/, but if you give a name_for_the_key, the generated files are saved in your current working directory.Ģ. Generate private and public keys (client side) In /etc/ssh/sshd_config, set passwordAuthentication yes to let the server temporarily accept password authenticationĬonsider Cygwin as Linux emulation and install & run OpenSSHġ. Setting ssh authorized_keys seem to be simple, but it hides some traps I'm trying to figure. Why isn't it logging me in without a password? Then it asks for a passphase after the above log. debug1: Reading configuration data /home/john/.ssh/configĭebug1: Reading configuration data /etc/ssh/ssh_configĭebug1: Connecting to localhost port 22.ĭebug1: identity file /home/john/.ssh/identity type 1ĭebug1: identity file /home/john/.ssh/id_rsa type -1ĭebug1: identity file /home/john/.ssh/id_dsa type -1ĭebug1: Remote protocol version 2.0, remote software version OpenSSH_4.7p1 Debian-8ubuntu3ĭebug1: match: OpenSSH_4.7p1 Debian-8ubuntu3 pat OpenSSH*ĭebug1: Enabling compatibility mode for protocol 2.0ĭebug1: Local version string SSH-2.0-OpenSSH_4.7p1 Debian-8ubuntu3ĭebug1: kex: server->client aes128-cbc hmac-md5 noneĭebug1: kex: client->server aes128-cbc hmac-md5 none I have followed the instructions for changing permissions:īelow is the result if I do ssh -v localhost. Is there another setting that I have to go through to make it work? I did that and tried typing ssh localhost, but it still asks me to type in the password. ssh localhost should log me in without asking for the password. I added the public SSH key to the authorized_keys file.
