One small typo:
Note: ssh-copy-id appends the keys to the remote-host’s .ssh/authorized_key.
should read
Note: ssh-copy-id appends the keys to the remote-host’s .ssh/authorized_keys.

Notice authorized_key*s* . Thanks for the article!

I’ve done this before, but wanted a quick reference check. I’d not come across ssh-copy-id. Thanks!

Please try with one of the following:
ssh-copy-id -i -t ~/.ssh/id_rsa.pub ip.ip.ip.ip
ssh-copy-id -i -q ~/.ssh/id_rsa.pub ip.ip.ip.ip
ssh-copy-id -i -T ~/.ssh/id_rsa.pub ip.ip.ip.ip
else, use another method,
#scp ~/.ssh/id_rsa.pub user@remotehost:/home/user/
This will ask you the password of the user you have mentioned
#cat id_rsa.pub >> /home/user/.ssh/authorized_keys

Thanks,
Jai

ssh-copy-id -i ~/.ssh/id_rsa.pub ip.ip.ip.ip
I get the following error.
root@ip.ip.ip.ip’s password:
stdin: is not a tty

Please advice

Thanks

Geeks,
If ssh-copy-id command not found on your system please use the following method.
#scp ~/.ssh/id_rsa.pub user@remotehost:/home/user/
This will ask you the password of the user you have mentioned
#cat id_rsa.pub >> /home/user/.ssh/authorized_keys

that’s it, you have done it.

@Sathiya, Yeah, lot of people overlook ssh-copy-id, as you can still copy the keys manually. @mk_michael, I believe you are talking about the keychain tool that is mentioned in gentoo.org. I have not used this before. Thanks for bringing this to our attention. I'll check it out. @Jadu Saikia, Thanks for your comments. I appreciate it. @domainnameyahoo, You may want to run the ssh in debug mode to identify what could be the problem. Please refer to section 4 in the 5 Basic Linux SSH Client Commands on how to debug ssh client connection.
