How to start or stop daemon in silence

S

sonysun

Hi;

I run a custom script at boot by using /usr/local/sbin
In this script I stop a daemon : [CMD="/usr/local/etc/rc.d"]samba stop[/CMD]

When this command is run I read on the screen an error because winbindd is not running.

I've tried things like [CMD="/usr/local/etc/rc.d/"]samba stop &>/dev/null[/CMD] but this is not working.

Is it possible to start/stop a daemon without output ?

Thanks
 
I remember having this same problem with winbindd a few weeks ago. I hacked the rc script to make it shut up, but don't remember the specifics of what I changed. If you want, I'll post it Monday if you haven't figured something out.

If you just want to suppress all output, I believe you have to use bash and use the 1>/dev/null 2>/dev/null to redirect STDOUT and STDERR.
 
Try
command 2>/dev/null (suppresses error output)
command > /dev/null 2>&1 (suppresses all output)
command 1>/dev/null 2>/dev/null (same)
 
Use this:
Code: 
nmbd_enable="YES"
smbd_enable="YES"
Instead of
Code: 
samba_enable="YES"
 
I believe I tried doing that SirDice, but no dice - same message popped up. (And yes, I intended that as a pun. :) :e ) I also tried setting winbindd_enable, also to no effect.

I just looked at my samba startup script and can't find what I changed. Further, I neglected to keep a backup copy of the original. :( Here's the entire thing - maybe you could run a diff on it against your own and post the changes, both for future people who view this thread and so that I don't drive myself crazy trying to figure out what I changed?

Here is your change in the script:

You have added ->
Code: 
# Hack to work around name change of pid file with non-default config
pid_extra=
if [ -n "${samba_config}" -a "${samba_config}" != "${samba_config_default}" ]; then
    pid_extra="-$(basename "${samba_config}")"
fi

In my default start/stop script for samba this does not exist. So there is no variable called pid_extra, and that's why the default script does not work. Shame on port maintainer.
