In reply to MM0FMF:
If anyone is trying to connect to the SOTA cluster using PuTTY then set the protocol to Raw and not Telnet. PuTTY being a good piece of software implements the Telnet protocol properly. However, as I am a lazy oaf, I don’t implement Telnet properly. Thus PuTTY (in Telnet mode) and the cluster do not get on. In Raw mode, they’re fine.
