SSH- Server connection automation

---

Explanation

This is a shell- script for linux, which was created to automate the process of connecting to an SSH- Server.

The script was initially created to connect to the ARM- SSH- Server of the TU Darmstadt, but is now modified to be used with other SSH- Servers.

The script is designed to use a public and a private key, generated with putty, to authenticate yourself. But in Version 2.2.0, a version was added to make a Unix- only key authentication.

How to use

General

To use this implementation, just run the script. However, you need to provide youre username and the SSH- Servers address with the corresponding flags.

./openssh_autoconnect.sh -u yourUsername -l SSH-link

If a key is needed as well, you need to use the -k flag. The script supports a cross- plattform key in the form of .pem- files and unix- only form.

./openssh_autoconnect.sh -k -u yourUsername -l SSH-link

If not key is specified, the program will look for a key in your directory

Cross- Plattform

You can also specify the .ppk or .pem key you want to be used. Just type the corresponding flag (-ppk/ -pem) followed by the file- name of the key.

./openssh_autoconnect.sh -k -u yourUsername -l SSH-link -pem Key.pem

If you haven't yet made the connection, just use the -new flag

./openssh_autoconnect.sh -k -new -u yourUsername -l SSH-link -pem TheKey.pem

Unix- only

You can specify the key- path for Unix- only initialization using the -unixkey flag, combined with unix

./openssh_autoconnect.sh -k -unix -unixkey pathToKey -u yourUsername -l SSH-link

General Options

The -k flag is only for setting up the key. If all keys are already created and you just want to initialize the connection, you can remove the -new flag.

Other options are the --help and --v/ --version flags to show the corresponding man- page from the program.
