Hi group,

Is there a way of streaming output from minicom to a web page?

A bit of searching came up with this php class to read a serial port. No idea how well it works.

https://github.com/Xowap/PHP-Serial

I should have been clearer. I want to stream the output of any program, like xload which outputs a GUI or a terminal window. But thanks for your comment.

I found this:http://https://www.raspberrypi.org/f...?f=67&t=122583But have not been able to verify it works. Keep you posted.

i'm not a specialist in this area, but from what little information/explanation you provided:

i think you are trying to reinvent the wheel.

certainly you're not the first person that wants to see graphical content remotely!
look for how it has been solved already!

if that doesn't help, please re-explain what you are trying to achieve, in as much detail as you can.

edit:
before you even tell us what you want, a check list:

• machines involved (hardware)
• machines involved (operating system)
• currently setup working setup (server software, modifications by you, tutorials followed etc.)
• network: local (at home) or global or...?

when you tell us what you want:

• desired outcome
• reason
• attempts made, reasoning behind those attempts, and why they failed, incl. (and this is most impoprtant) actual command output!

You are right, I am always looking for the quick and simple fix for my problems. Sorry. Let me first say I am Learning Disabled ( Dyslexia ) and reading is difficult for me and writing, thanks for spell check.

• machines involved (hardware)
  • I plan to use a Raspberry Pi 3.
• machines involved (operating system)
  • Using Raspbian.
• currently setup working setup (server software, modifications by you, tutorials followed etc.)
  • My server is up and running LAMP.
• network: local (at home) or global or...?
  • World wide.

• desired outcome
  • Want to stream to a web page varies program outputs.
• reason
  • To monitor run status.
• attempts made, reasoning behind those attempts, and why they failed, incl. (and this is most impoprtant) actual command output!
  • Have not found any solution that have provided any output.

My Plan is to use this setup to provide remote support.
So far, I have looked at using 'telepi', VLC and ffmpeg.
Many posting found on Google but nothing working yet. A lot of reading to be done.

Thanks for your inputs.

The usual way to provide remote support or to monitor a system would be via SSH. Raspian has OpenSSH-server in the repository and you can install that. There are a lot of shortcomings to trying to run things via the browser, complexity and lack of security are two.

If you want to leave a long-running process going on the remote machine and check on it periodically, then you can run tmux on the far end and re-attach to it when you re-connect via SSH.

What specific activities do you want to do remotely?

Yes, I use SSH very often, but I plan to allow remote users to use the interface with out using SSH. By using a web page, I can limit the kinds of activity that would be harmful to my server.

A restricted shell, such as rbash (aka bash -r), along with maybe a chroot would do that in SSH.

As far as limiting activities go, both in theory and in practice, whitelisting works. Ban everything and then allow in one activity at a time until you have allowed all the activities you want them to be able to do.

Along the lines of whitelisting activities, OpenSSH has the ForceCommand configuration directive that can be applied to specific groups of users. That will restrict them to automatically running only a single program. However, you could choose for that single program to be a script of your making which then reads a multiple-choice either from stdin or from the SSH_ORIGINAL_COMMAND environment variable.

There is also an equivalent command="" that can be embedded in authentication keys to make the keys single-purpose.

mrumunhum, you missed the first and most important part of my post:
what you want has been implemented already, but not in the way you imagine.
those are complete applications specifically for the task of remotely monitoring a server.

I found a solution, Open Broadcast System ( OBS ). It does exactly what I want. I am testing it on my laptop, very promising.

you mean this one:

?

Yes. On my Fedora 23, I just did "dnf install obs-studio". Took some time to figure out who to use it but I found a youtube video that helped me. One problem, it is not supported on the Raspberry Pi! Thinking about porting it?

nice try.
