[Lcd4linux-devel] Lcd4Linux isn't forked?

[Martin Z. <co...@mz...>]

Hi!

As of new, "lcd4linux" (from SVN) doesn't run unless I specify the "-F" 
command line option.  It starts, but it directly quits.  I.e.,

   # lcd4linux -Fq
   # pgrep -l lcd
   10968 lcd4linux

runs, but

   # lcd4linux -q
   # pgrep -l lcd

does not.  Any ideas?

That was a pretty short email for me, wasn't it? ;)

Huh? Never seen that before...

as lcd4linux should use syslog, any hints from there?

Dear Michael,

I might have had the sense to look at syslog myself.  Anyway, I'm not 
running "lcd4linux" as root and the directory permissions on my 
Debian-based systems were too restrictive:

   mkstemp(/var/run/lcd4linux.pid.6X3ybP) failed: Permission denied

For users who stumble across this -- I simply changed the permissions of 
"/var/run" by the commands:

   sudo chown root:admin /var/run/
   sudo chmod 775 /var/run/

and everything's fine again.  Although this relaxes security a little, 
users runnning "lcd4linux" still have to be in the group "admin" to 
write to "/var/run".

Thanks,

Martin

P.S.: Is everybody *really* running "lcd4linux" as root?!?

Hi!

After thinking about it, allowing anyone to write in /var/run/ (whether 
they are within the group "admin" or not) is a heavy security problem 
and shouldn't be done.  Even running "lcd4linux" and thereby its python 
plugin as "root" is better, so I do that now.  Sorry for my mistake.
