incorrect permissions /dev/lp0 and /dev/usb/lp0 about thinstation

[trentasis]

Hi @Doncuppjr

After some tests I have found:

It seems that in /etc/udev/rules.d/99-udev.rules related with printers are not applied
KERNEL=="lp[0-9]*", SYMLINK=="printers/%n", OWNER="root", GROUP="lp", MODE="0666"

and if you replace by
KERNEL=="lp[0-9]*", GROUP="lp", MODE="0666"

then works, but I'm not sure why SYMLINK was defined because without this /dev/usb/lp0 persist and seems correct... It could be for multiple printers or works without?
@Doncuppjr do you know why exist this rule and what do you think about my suggestion?

I have found this rule debugging with default rules that really are applied from
/lib/udev/rules.d/50-udev-default.rules

@Doncuppjr What do you think?

Thanks

Might be an udev rule issue.

Where I can check this and comapre with 2.2 version?

[Thinstation]

2.2 did not use udev for hardware detection. It's hard to make this comparison. I'll try and take a look at this over the holidays.

I have tried to replace in /ts/build/packages/automount/etc/udev/rules.d/99-udev.rules

KERNEL=="lp[0-9]*", SYMLINK=="printers/%n"

by

KERNEL=="lp[0-9]*", SYMLINK=="printers/%n", MODE="0666"

But permissions are the same 660...

Where could be the problem?

Thanks

I don't know, just works for me, problems weren't.

hi,

can you show ls -lisah /dev/usb/lp0 output after boot thinstation and same command after disconnect and connect usb printer? I like to compare both results.

thanks

[Doncuppjr]

Shouldn't be to hard. Boot TS, run the command. Disconnect and Reconnect printer, run command again. Did I miss part of the challenge?

Hi @Doncuppjr ,

I have detected that seems that udev is not applying this changes, also tried with script like is used in floppy devices, but udev rules cahnge is not working but if you execute the commands manually works. Do you know if we need any other modification in thinstation to refredh this change to udev rules?

Thanks

blockquote, div.yahoo_quoted { margin-left: 0 !important; border-left:1px #715FFA solid !important; padding-left:1ex !important; background-color:white !important; } I don't know. You might try simulating the event in udev, to see what order the rules are applied, and if that one is being applied correctly.
