ssh-key-exchange

ssh-key-exchange (ske) changes the way you set up key-based ssh communication between two or more computers. ske performs all the necessary steps that you must perform before key-based authentication can begin.

1. ske generates the necessary private and public key for the computer on which ske is started (it also takes an existing key pair).
2. ske connects to the remote computer via a password and adds the public key to the authorized keys
3. then ske checks whether the key-based authentication works or not
4. you can define a range of remote computers for which key-based authentication should be set up
5. at the end a short report is generated

Build

for the local environment (os and architecture)

make build

or (for all possible environments)

make build-all

Example usage

You can try out the different options of ske with:

ssh-key-exchange -h

For testing ske you can use a tiny ssh-server from docker-hub

# first terminal
docker run --rm --publish=2222:22 --name ssh-server-local sickp/alpine-sshd:latest

# second terminal
## generating (you have to specify the password)
ssh-key-exchange --host 127.0.0.1 --port 2222 --user root --rsaKeyGenerate

## ssh shell key-based
ssh -o StrictHostKeyChecking=no root@127.0.0.1 -p 2222

Stopping the ssh-server as follows:

docker stop ssh-server-local
