In Firewall-Advanced, iStatLocalDaemon, sshd-keygen-wrapper, and synergys are blocked (synergys is blocked because I want it to only allow connections on localhost which would include SSH-tunneled connections).In Firewall-Advanced, Remote Login (SSH) is shown as allowed.In Sharing, Remote Login is the only thing checked and it is set to only allow my user.Settings for firewall/Remote Login on MBP: I upgraded to 10.6.1 days ago, so that can't be it either. Everything worked properly yesterday, but this morning when I tried to setup my SSH tunnel to run synergy (

Now you will have to move the private key to the system at that location from where you are going to run the ssh command, then you can connect with sshpass -p 'password' ssh -i id_rsa even that doesn't work then go in /etc/ssh open sshd_config with vim editorĬheck if the pubkeyAuthenticatoin is turned to yes or not, if not change it to yes, restart the sshd services and then try it, it will definitely work.First of all, does 10.6.1 still use ipfw as the underlying firewall? If so, then the 'ipfw list' output I will be pasting in will be of use, if not then just ignore it.Ģ laptops, one a Dell Latitude D630 running XP with Cygwin's ssh as the ssh client, the other a MacBook Pro (unibody, 2008) running 10.6.1. Now go to home directory and give permission and restart sshd services chmod 700 /home/username/.sshĬhmod 644 /home/username/.ssh/authorized_keys ssh folder and change the public key name to 'authorized_keys' cd. It will ask you for passphrase, you can also leave it empty It will generate private and public keys and ask you for a location, leave at empty it will save the keys in. I recently did this, this may help you: sshpass -p 'password' this doesn't work then you'll have to generate keys in the other machine you want to connect with ssh-keygen

This is a much preferable method of managing automated logins as you don't end up hard-coding your password multiple places that need to be updated if you ever change it.

Many Linux and macOS versions come with SSH installed by default, although typically disabled until the user enables it. Now, to put it into action on your local machine you run the following command: ssh -i ~/.ssh/mysshkey Īnd you will be logged in without being prompted for a password.

SSH is a protocol that allows authorized users to open remote shells on other computers.

Make sure that ~/.ssh/authorized_keys is chmod'd to 600.

Copy and paste the contents of mysshkey.pub into ~/.ssh/authorized_keys.

mysshkey is your private passwordless key, it is not safe to put on remote servers (or somewhere someone else could get a copy). mysshkey.pub is your public key, this one is safe to put on remote servers. There will now be two files in your ~/.ssh directory, mysshkey.pub and mysshkey.

Press Return when prompted for passphrase.

This is a security risk if your private key is stored somewhere that it could be stolen. What you want to do is generate a passwordless ssh-key pair and then (as long as the server supports RSA key authentication) you can get in without having to type a password for all.
