How to connect to OpenStage 40 using SSH

First, enable SSH access on the webinterface:

Admin pages -> Maintenance -> Secure Shell

Enter a random password, choose other settings as shown.

Click submit. At this stage, choosing to ssh admin@192.168.178.245 would lead to the following error message:

Unable to negotiate with 192.168.178.243 port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,kexguess2@matt.ucc.asn.au

Therefore we have to use the following command:

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 admin@192.168.238.245
