Pedigree Live Demo

pcmattman · **Posted:** Wed Jun 18, 2014 6:15 am

Hello all,

I've set up a VM running Pedigree on a VPS that anyone can SSH into and play with. The system is set up with a watchdog timer, so if the system hangs or crashes, it will be automatically rebooted (and the kernel log will be preserved too, for post-portem investigation). No ISO to wait for an hour to download, no fiddling with emulator configuration, just a system already at your disposal.

Example:

Code:

$ ssh -p 2222 [email protected]
Welcome to Pedigree.
This is Pedigree Unstable -- 0.1.3
Welcome to the Pedigree operating system.

Please don't feed the code monkeys - they bite.
[12:02:20] ~ $ make
gcc -O3 -o hello hello.c
[12:02:26] ~ $ ./hello
Hello, world!
[12:02:28] ~ $ make clean
rm -f hello
[12:02:31] ~ $ ls
Makefile hello.c
[12:02:31] ~ $ ls ..
ssh test
[12:02:38] ~ $ ls /
applications boot config etc include keymaps libraries support system users
[12:02:39] ~ $ logout
Connection to build.pedigree-project.org closed.

So just point your favourite SSH client at build.pedigree-project.org, user 'ssh', port 2222, and give it a spin

if you do so and find something broken, please reply in this thread, ideally with a transcript of what you did (and a timestamp+timezone

) to cause the issue.

Also, http://build.pedigree-project.org/livestatus hits a HTTP server running in Pedigree on the same VM, so if SSH isn't working right, check that the HTTP page renders properly. A HTTP 502 means the VM is down.

Note that currently http://pedigree-project.org is down; you can see the latest work at https://github.com/pcmattman/pedigree.

Happy testing!

When I tried SSH'ing (authenticating as user 'ssh') I get:

Code:

Welcome to Pedigree.
This is Pedigree Unstable -- 0.1.3

Then it disconnects. I'm using PuTTY on Windows 7.

On Linux, I can connect fine via SSH. Very cool.

I have a strange issue when I type. It echos back the first character (but doesn't seem to input it) and inputs the rest of the characters (without echo'ing it).

E.g. I can type:

5ls [enter]

and it prints:

"[14:59:25] ~ $ 5Makefile hello hello.c"

Anyway, just a minor issue. Great work!

EDIT: I tried reconnecting and now it works fine.

Works from a linux client. Quite laggy though.

Glad to see your operating system is steadily improving. :-)

Unfortunately, it still appears to be very unstable. In my latest try I couldn't even run ls without the shell eating the s and then complaining there was no l program.

pcmattman · **Posted:** Wed Jun 18, 2014 3:11 pm

Thanks for the testing!

Sortie - can I get a transcript of that happening, including the working directory? I can't immediately reproduce the behaviour.

bluemoon - it looks like the first disconnect was a watchdog action - I'll check the kernel log and I expect there'll be a fault. The reconnect seems to be around the same time Combuster rebooted the VM

MessiahAndrw - do you mean after a reconnect the shell worked as expected, or PuTTY worked and the weird shell behaviour remained?

BTW, shameless plug for #pedigree on Freenode IRC

PuTTY on my Windows PC never held a connection, it always dropped off after printing two lines - I moved on to testing on Linux with 'ssh'. 2 out of the 3 times I ssh'd from Linux I had that weird shell behaviour (it echoed back but did not input my first character, then the rest of my characters were invisible) 1 time the shell worked as expected.

This command:

Code:

ls -l /dev/

gives me ~reproducable ~scrambled output - some part of output misses \r characters, only \n.
I think that this problem has the same root as above described problems with character-eating shell (some kind of race condition in pipe/buffer implementation?).

Btw, 'chroot' binary is present but "Function not implemented", is this feature planned to be implemented in near future?

ls and make in ~ are killed by Segmentation fault

They should now work again (a minor regression that existed for a couple of days).

Thank you all for the reports - I have an interesting selection of bugs to work through!

The SSH server will continue to remain available.

The

Code:

#!/bin/sh -

line in bashbug seems to not work, perhaps due to the -. I tried to edit it with vim over ssh, but that was an awful and buggy experience and I gave up.
