Synology router “RT1900ac” – my christmas toy

[2015-12-20 00:27:39] johayek@Hayek001 $ ssh

BusyBox v1.16.1 (2015-10-29 15:37:59 CST) built-in shell (ash)
Enter 'help' for a list of built-in commands.

SynologyRouter> ./config.guess
SynologyRouter> ./config.guessJHn 
=config.guessJHn,0: $config_unique=>{synology_northstarplus_rt1900ac},$config_buildnumber=>{5781},$config_smallfixnumber=>{2} // ...

  • rsync – as opposed to the “tainted” rsync that Synology provides
  • less – as opposed to poor old more

For my 1st steps I attached its WAN port as a client to my VDSL router. Good for updating, good for getting acquainted with its features.

I disconnected that cable, and I attached these sticks / dongles successfully:
