How do I use the SSH server on kobo? All I get is connection refused.

The link to the user manual (read the manual, on http://pcbchess.vlasovsoft.net/en/index.html) 404's http://pcbchess.vlasovsoft.net/en/manual.html

Also, for registration: Not only chess, but also checkers and the other games display notifications and time out in the non-registered version. If I register PCBchess, is this also for these other programs?
