= cssh & cscp: ssh and scp wrappers to connect to dev servers

The scripts read your `.ssh/config` to get the password used to connect to a server.
They additionally read your ssh keys from the same file.

Normally, for passwordless ssh you would have the following in your `.ssh/config` file:

[source, conf]
----
Host server
  Hostname server.domain.com
  User ec2-user
  IdentityFile ~/.ssh/aws-keys/server.domain.com.pem
----

And you would connect with `ssh server`.

However, lets say, you are using QA/Development servers and setting up a host entry takes a lot of time.
You could do:

[source, conf]
----
# DefaultIdentityFile ~/.ssh/aws-keys/dev.key.pem
# DefaultIdentityFile ~/.ssh/aws-keys/qa.key.pem
----

And connect using the IP:

`cssh ec2-user@12.34.56.78 --key 0`

The script will read all the available keys and use the first one (index 0).

For local servers, you might not have an ssh key setup but a default password:

[source, conf]
----
Host qa1 # qaPassword
  Hostname qa1.domain.com
  User root

Host * # devPassword
    User root
----

The script can be run as:

`cssh qa1`

And it will automatically read the password from the `.ssh/config` file entry.
Additionally, for every other server, it will try to use the `devPassword` password.
