I am trying to connect to local ip via SSH from terminal. Command is

ssh -v user@

But it is not connecting. Keeps giving me the error "Permission denied (publickey,password)." I have been searching for ages and just cant find what the issue is. I can connect using the same method via Putty on windows and can connect via filezilla

Full output:

  • From the output, it looks like ssh is trying to use an identiy file (lines 5-8 inclusive). If you have an identity file you are using, be sure the permissions are set so only the owner can read/write. – Sarge May 8 '15 at 23:10
  • What should the permissions be? -rw------- 1 Username staff 314 9 May 00:08 id_ecdsa -rw-r--r-- 1 Username staff 199 9 May 00:08 id_ecdsa.pub -rw------- 1 Username staff 1766 8 May 22:40 id_rsa -rw-r--r-- 1 Username staff 419 8 May 22:40 id_rsa.pub -rw-r--r-- 1 Username staff 799 8 May 23:10 known_hosts – Harnamc May 8 '15 at 23:12

try to add the key again. first set PasswordAuthentication yes in sshd_config at dest machine, then do ssh-copy-id user@host log in, then it will copy the key over. Now you can set PasswordAuthentication no(if you want, for extra security) , and you should be able to log in automatically. You could also use your curiosity and check if id_rsa.pub from the source machine is in authorized_keys on the dest machine

  • also, I don't think permisions are the issue, but i've read that chmod 600 is fine for all files in ~/.ssh with 700 for the directory itself so you can list the files in it. Certainly anything less would be a problem – barlop May 9 '15 at 1:05
  • Spot on mate! worked like a charm – Harnamc May 9 '15 at 10:05

It might be different because it looks like you are connecting to localhost or something ( or is that just for the question?).

What often solves things like this is to edit the ~/.ssh/known_hosts file and delete the entry for the domain you are connecting to, it will re-prompt you for ssh credentials and avoid problems caused by incorrect "expectations".

  • The localhost is a local vpn server that has ssh enabled. I can connect to it from any other means. I have deleted the entire in the ~/.ssh/known_hosts and also completely removed the file and recreated it. But the problem still exists. Its issue is just when trying to connect from my mac. I have tried connection via putty from my window laptop and it works fine. Even sftp via filezilla works perfectly fine. – Harnamc May 9 '15 at 0:55
  • Also try deleting id_rsa.pub ? – beroe May 9 '15 at 1:11
  • @beroe I think id_rsa.pub doesn't do much. I vaguely recall from a test that it seems ssh works the same with or without id_rsa.pub . I think ssh doesn't use the public key in the pub file even though the contents are the same. – barlop May 9 '15 at 1:39

    Tried removing and recreating all the keys still had same problem. What worked was set PasswordAuthentication yes in sshd_config and copy keys accross with ssh-copy-id user@host – Harnamc May 9 '15 at 10:34
  • Glad you got it figured out and thanks for the update. – beroe May 9 '15 at 15:38

first run cat $HOME/.ssh/id_rsa.pub on your computer you will get a key. save this key somewhere.

Then open this file by running vim $HOME/.ssh/authorized_keys on the computer that your are sshing to. Then copy the key in a new line of this file and close it by typing :wq

you are all set.

  • On top of that OpenSSH package includes ssh-copy-id command which basically does the some in one command – maoizm Oct 22 '18 at 21:11
