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

Comment by linuxrawkstar 398 weeks ago

So let's make things straight. This is the corrected line:

for i in `ls --color=none /sys/class/net/*`; do echo "# $i"; sudo ethtool $i | grep -E "Link|Speed" ; done

Comment by dotanmazor 397 weeks and 4 days ago

What? This can't work like that. It will pass the whole path to ethtool and fail. You should have the command cd into /sys/class/net before doing an ls, a such:

for i in `cd /sys/class/net ; ls -d *`; do ...
