Howdy,
So my understanding was if you put a file called 'chumbydebug' on a thumb drive and conect it to the USB that it will run. So /bin/sshd should, in theory, work.
It isn't working for me, or for at least one other person on the wiki...what magic incantation are we missing?
Cheers,
Rich
1) The file must be called "debugchumby"
2) It must be at the root level of the file system on the USB device
3) It must be marked executable
If it is a script (mostly likely), it should have the typical bang header:
#!/bin/sh
/bin/sshd
This is not a feature you can count on - it may be removed or changed at any time.
Debugchumby, chumbydebug, what's a little misordering amongst friends :-)
Is there a way to run things that is likely to be more permanent?
3) It must be marked executable
Does this imply that the file system on the USB drive should be something other than FAT? (Since FAT doesn't have permission bits). If so, what file system should the USB drive be formatted with?
I tried putting a "debugchumby" file containing the suggested text on a USB drive formatted w/ FAT, and booting up chumby with the drive plugged in, but without success.
Well, if it doesn't work, well, sorry about that. It's not an official feature.
It was a very late addition that probably wasn't tested very well. I'll play a bit with mine to see if I can come up with something that works reliably.
i think the wiki says it has to be a mac formatted stick.
No...the wiki says (or should :-) that it _can't_ be Mac HFS...please fix the Wiki if it says otherwise!
you guys should implement a package system for chumby. make it a bit easier for people to activate things like sshd and httpd

httpd is started automatically. There is, in fact, an easier way to start sshd (without the use of a USB stick/script or attaching to serial debug), but its up to -you- to find it!

Forgive my daftness, but how exactly would a package system help activate a service? I could see it for /installing/ services, but we've been made quite clear they're not supporting installing things on the Flash RAM.
What would be easier is a webpage that could configure services, etc. which is what I *believe* Ken was alluding to, but can't be positive as I don't own a Chumby.
well it doesnt, but it would be easier for downloading widgets, and other stuff.
ken, im open to that challenge. send me a chumby and ill find it 
This is an interesting challenge Ken. I'm not sure you're right about that. I've been searching the code on the CD and haven't found anything to conclude that it's somehow easy to start busybox's sshd from within the UI or by doing anything to the chumby itself. Is the code on the Foo Camp CD identical to the code running on the chumbys we received?
One could conceivably write a widget to run the external program, but that is beyond my current flash capabilities...albeit fairly easy, one assumes.
I believe they said that the code for the easter egg that starts sshd is in their modified version of flash (i.e., you won't be able to find it by searching the code). So we'll just have to keep trying things on the chumby.
I'm still trying to make progress on running sshd from a chumbydebug script, but I haven't had any luck yet. I tried using an ext2fs formatted drive, which I saw suggested somewhere, but that didn't seem to help.
I'm not sure if the ".config" file in the distributed kernel-src.tar.gz is accurate/up-to-date, but if it is, then it appears that EXT2FS support isn't even compiled:
[~/chumby_kernel]$ grep EXT2 .config
# CONFIG_EXT2_FS is not set
File systems that *do* appear to have support compiled:
[~/chumby_kernel]$ grep _FS=y .config
CONFIG_FAT_FS=y
CONFIG_MSDOS_FS=y
CONFIG_UMSDOS_FS=y
CONFIG_VFAT_FS=y
CONFIG_JFFS2_FS=y
CONFIG_PROC_FS=y
CONFIG_DEVFS_FS=y
CONFIG_ROMFS_FS=y
CONFIG_NFS_FS=y
If anyone with a foo-camp chumby does manage to get sshd running via a usb chumbydebug script, please post a detailed description of how you did it to the wiki. 
This works with the latest software releases... but keep in mind that sshd is actually in /sbin/sshd and not /bin/sshd
