Oracle clients

A short list:

• dbVisualizer
• Toad
• Oracle SQL Developer

Example ssh config

Host [alias]
    HostName [remote hostname]
    User [remote username]
    IdentityFile [file]

[alias] is what you type to select the connection, e.g. ssh [alias]

[file] is your DSA or RSA private key file

Log into a server using secure keys instead of typing a password

On the client:

1. ssh-keygen -t rsa
2. accept the default filename
3. press enter for a blank password
4. a private (id_rsa) and public key (id_rsa.pub) will be created
5. copy the public key to the server
   

On the server

1. cat id_rsa.pub >> ~/.ssh/authorized_keys
2. chmod 700 ~/.ssh
3. chmod 644 ~/.ssh/authorized_keys

Now back up your keys.

(Upon error "Agent admitted failure to sign using the key", log out of the client and log back in again to fix).
