/etc/rc.d/rc.local doesn't execute at start

Reedych · 01-05-2017, 11:43 AM

I use slackware arm current. It contains only ntpdate. I gave a execupermission him:

Code:

-rwxr-xr-x  1 root root  377 Nov 27 14:43 rc.local

Can you run rc.local from the command prompt?

Code:

root@slackwarearm:~# /etc/rc.d/rc.local

Show us the output of

Code:

cat /etc/rc.d/rc.local

Also does your system get to the login prompt on the console?

Code:

#!/bin/sh -e

# /etc/rc.d/rc.local:  Local system initialization script.

# Put any local startup commands in here.  Also, if you have
# anything that needs to be run at shutdown time you can
# make an /etc/rc.d/rc.local_shutdown script and put those
# commands in there.


# set system date/time at boot from ntp server [rpi3-hacks-3.0]
ntpdate 0.pool.ntp.org > /dev/null &

I login using ssh.

run that off you command line without sending it to NULL to be sure that it works, you may be missing a PATH

In addition to BW-userx's advice, use a full path when troubleshooting command issues. Sometimes it makes all the difference.

Code:

root@slackarmbox:~# /usr/sbin/ntpdate 0.pool.ntp.org 
 6 Jan 20:56:16 ntpdate[33229]: adjust time server 163.172.216.210 offset 0.000318 sec

You can also check your PATH with:

Code:

root@slackarmbox:~# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Added /usr/sbin to ntpdate, thanks!

/usr/sbin/ was needed to add to ntpdate, but thanks!

this is why it is good to always check it in the command line if it isn't working to see the feedback in the terminal. Then you can go into troubleshooting mode from there.

Usually it suffices to comment out the >/dev/null

Code:

ntpdate 0.pool.ntp.org # > /dev/null &

and get the error even on the boot (if any screen attached)

Using full pathnames in boot scripts is always a good idea, as a safeguard against a rogue PATH to compromised binaries.

As for running this script from the command line, one way to watch the execution without modifying the script is to use:

Code:

# sh -vx /etc/rc.d/rc.local

and you can see each line as it is executed.
