Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

In exemple, screen can bind keys to switch between windows. I like to use Ctrl + Arrow to move left or right window. So I bind like this in .screenrc :

bindkey ^[OD prev # Ctl-left, prev window

bindkey ^[OC next # Ctl-right, next window

[ -n "$SSH_CLIENT" ] && export DISPLAY=$(echo $SSH_CLIENT | awk '{ print $1 }'):0.0

In some case, you need to use remote gui on servers or simple machines and it's boring to see "cannot open display on ..." if you forgot to export your display. Juste add this line in .bashrc on remote machine. Dont forget to allow remote client on your local X server :

xhost +
alias s='ssh -l root'

When you have to manage lot of servers, it's boring to type ssh [email protected] for each connection. Now you can type juste "s someting" and you are connected.

You can too add bash_completion script to complet with tab the name of your servers. This will be the next tips from me ;)
