So I am mucking around with my Siglent waveform gen unit and want to try a software hack that has the ability to increase it from a maximum of 30mhz to 60mhz

You can Telnet into the unit and you are presented with this prompt.

(none) login:

I will be honest when I say I have no idea the (none) part in front of the login means. Could it be there is no username and just a password ??.

I know it will probably have to be brute forced which I am happy to play around with just not sure what username to use.

Anybody have any idea.
