  1. sudo usermod -a -G adm,dialout,cdrom,sudo,audio,video,plugdev,games,users,netdev,input rtwomey
  2. logout, then login

SSH Login

ssh login:

  • should work by default. you just need to know the IP address.
  • Connecting to local mac it through netgear box, it's probably 192.168.2.3, or 192.168.2.2.

Store your public key on the remote system, so you aren't prompted for password: http://www.linuxproblem.org/art_9.html

not resolving IP addresses

  • sudo vi /etc/resolv.conf
  • add the line nameserver 8.8.8.8
    • this is the google nameserver.

vnc remote

scp

  • to copy photos to my current computer, over ethernet cable:
