I am working with serverals hosts and I do not want specify the password every time that I want to connect to any hosts. Then I have generated a key with:
Enter file in which to save the key (/home/robe/.ssh/id_rsa): my_key
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in my_key.
Your public key has been saved in my_key.pub.
The key fingerprint is:
e6:d9:a3:85:38:b1:b2:a9:4d:3b:c1:33:65:df:57:25 robe@computer
The key's randomart image is:
+--[ RSA 2048]----+
| |
| E .|
| o |
| o . |
| . o..S. . |
| = *.+. . |
| o++ + +. |
| o.= . o . |
| ..=. . |
+-----------------+
then I copy the my_key.pub to the authorized_keys file in every hosts and I can connect with:
ssh -i /path/to/my_key user@host
But here is my problem, I want to connect without specify the key. I will like to find a way that I run:
ssh user@host
Note: I want to keep my default id_rsa and id_rsa.pub keys. The my_key key is an alterntive option to manage other hosts.
