Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

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

Remote Serial connection redirected over network using SSH

Remote Serial connection redirected over network using SSH

Requires software found at: http://lpccomp.bc.ca/remserial/

Remote [A] (with physical serial port connected to device)

./remserial -d -p 23000 -s "115200 raw" /dev/ttyS0 &

Local [B] (running the program that needs to connect to serial device)

Create a SSH tunnel to the remote server:

ssh -N -L 23000:localhost:23000 [email protected]

Use the locally tunnelled port to connect the local virtual serial port to the remote real physical port:

./remserial -d -r localhost -p 23000 -l /dev/remser1 /dev/ptmx &

Example: Running minicom on machine B using serial /dev/remser1 will actually connect you to whatever device is plugged into machine A's serial port /dev/ttyS0.

Alternatives

There are 10 alternatives - vote for the best!

Terminal - Alternatives

Know a better way?

If you can do better, submit your command here.

What others think

It would be nice with a command to initiate the ssh tunnel from the remote machine and i.e. it the serial port machine is behind a NAT firewall.
