There is no actual urchin as far as I know. The control file is
/usr/local/urchin/bin/urchinctl. It is a executable file:
urchin# file /usr/local/urchin/bin/urchinctl
/usr/local/urchin/bin/urchinctl: ELF 32-bit LSB executable, Intel 80386,
version 1 (FreeBSD), statically linked, stripped
After running /usr/local/urchin/bin/urchinctl start, I have these
related processes:
urchin# ps acux | grep urchin

nobody 70946 0.0 0.0 1332 668 ?? Is7:00PM 0:00.51 urchind
And conversely, /usr/local/urchin/bin/urchinctl stop removes all of
the above processes.
In your script command is path_to_urchinctl. rc.subr will look for a
process named urchinctl and a pidfile named urchinctl.pid. It appears
that neither will be found, so the script can't stop or restart the
processes, because it doesn't know the pid and therefore the process
that it needs to kill. That doesn't explain why it won't start the
processes though. I *think* you need to name the script urchin rather
than urchin-server, but I can't test that.
The rc script name does not seem to matter.
To fix the pid problem, rc.subr offers some optional statements that,
with the proper arguments, can overcome the problem. You'll have to
read man rc.subr and test it to figure out what works, but here's an
example that might work:
pidfile=/var/run/urchinwebd.pid
check_pidfile=${pidfile}
The problem here is that urchinctl does not write a pid file by default
and I can't figure out how to make it do so.
However in reading man rc.subr, I found argument_cmd that works for me.
By setting argument_cmd, I can override the default methods called by
run_rc_command. Thus I set these three lines:
start_cmd=/usr/local/urchin/bin/urchinctl start
stop_cmd=/usr/local/urchin/bin/urchinctl stop
status_cmd=/usr/local/urchin/bin/urchinctl status
Originally, I used $1 instead of start, stop, and status. However
this had the effect of making restart restart twice, once for the
start method and once for the stop method because
/usr/local/urchin/bin/urchinctl restart was being run each time.
If that does work, your script should at least be able to report the
status (running or not).
I also had to set the procname variable to make the status method
available. In my case, it didn't matter to what it was set as the
urchinctl command handled the actual status reporting.
I'm assuming that, because root is running the lowest numbered
process, killing that process will kill all the children as well.
Killing the root process killed all the urchinwebd processes but left
the urchind processes hanging around. But no matter, I got things working.
Thanks for your help!

Right. This ctl basically does what rc scripts are normally doing. So this is
the 20% case where many of rc's assumptions are incorrect and you need to
override this logic. The main is that the command is not the running daemon.
As such, one need to override the default start, stop, restart and status
commands.

There may be a way to kill the urchind processes as well. If you set procname to urchin, the rc.subr script might understand that to mean any process that begins with that string. I haven't tested it, but looking at the script (/etc/rc.subr), it appears to me to be the case. If that doesn't work, perhaps procname urchin* would. -- Paul Schmehl (pa...@utdallas.edu) Senior Information Security Analyst The University of Texas at Dallas http://www.utdallas.edu/ir/security/
Help With rc.d Script
I installed a software named urchin on my FBSD 7.2 box.
Unfortunately, it didn't come with an rc.d script to automate startup
and shutdown. And even more unfortunately, I can't seem to get my head
around the concepts in Practical rc.d scripting in BSD
(http://www.freebsd.org/doc/en/articles/rc-scripting/rcng-daemon.html).
This is the command that starts the app:
/usr/local/urchin/bin/urchinctl
And here are the options:
Usage: urchinctl [-v] [-h] [-e] [-s|-w] [-p port] action
where:
-v prints out the version of urchinctl
-h prints out this information
-e activates encryption (SSL) in the webserver
-s performs the action on the Urchin scheduler ONLY
-w performs the action on the Urchin webserver ONLY
-p specifies the port for the webserver to listen on
action is either: start, stop, restart, or status
start: starts the webserver and scheduler
stop:stops the webserver and scheduler
restart: stops and then starts the webserver and scheduler
status: prints out whether the webserver and scheduler are running
By default, the action is performed on both the webserver and the
schedulers unless the -s or -w options are specified
All I want to do is create a script within the rc.d framework that runs
/usr/local/urchin/bin/urchinctl start when the system boots and
/usr/local/urchin/bin/urchinctl stop when the system shuts down.
Following the examples in the guide mentioned above, here is my attempt
at that file:
#!/bin/sh
# PROVIDE: urchin
# REQUIRE: NETWORKING
# KEYWORD: shutdown
#

# Set it to YES to enable urchin.

Re: Help With rc.d Script
since the rc.d scripts (as much as lots of other scripts in BSD are..)
are borne shell scripts, can't 'set -x' be in the script to show the
flow of it running???
That's what I'd try first.

I installed a software named urchin on my FBSD 7.2 box.
Unfortunately, it didn't come with an rc.d script to automate startup
and shutdown. And even more unfortunately, I can't seem to get my head
around the concepts in Practical rc.d scripting in BSD
(http://www.freebsd.org/doc/en/articles/rc-scripting/rcng-daemon.html).
This is the command that starts the app:
/usr/local/urchin/bin/urchinctl
And here are the options:
Usage: urchinctl [-v] [-h] [-e] [-s|-w] [-p port] action
where:
-v prints out the version of urchinctl
-h prints out this information
-e activates encryption (SSL) in the webserver
-s performs the action on the Urchin scheduler ONLY
-w performs the action on the Urchin webserver ONLY
-p specifies the port for the webserver to listen on
action is either: start, stop, restart, or status
start: starts the webserver and scheduler
stop:stops the webserver and scheduler
restart: stops and then starts the webserver and scheduler
status: prints out whether the webserver and scheduler are running
By default, the action is performed on both the webserver and the
schedulers unless the -s or -w options are specified
All I want to do is create a script within the rc.d framework that runs
/usr/local/urchin/bin/urchinctl start when the system boots and
/usr/local/urchin/bin/urchinctl stop when the system shuts down.
Following the examples in the guide mentioned above, here is my attempt
at that file:
#!/bin/sh
# PROVIDE: urchin
# REQUIRE: NETWORKING
# KEYWORD: shutdown
#
# Add the following line to /etc/rc.conf to enable urchin:
# urchin_enable=YES (bool): Set to NO by default.
# Set it to YES to enable urchin.
. /etc/rc.subr
name=urchin
rcvar=`set_rcvar`
command=/usr/local/urchin/bin/urchinctl
eval ${rcvar}=\${${rcvar}:-'NO'}
load_rc_config $name
run_rc_command $1
I have also ensured that 'urchin_enable=YES' is in /etc/rc.conf.
However when I run the rc.d script, the urchinctl appears to run but
doesn't like whatever arguments that are passed. See this output:
urchin# ./urchin-server start
Starting urchin.
Usage: urchinctl [-v] [-h] [-e] [-s|-w] [-p port] action
snipped rest of options already shown above
I'm sure I'm missing some simple concept. I'd really appreciate a kick
in the right direction.
Thanks,
Drew

Where is urchin located? /usr/local/bin? /usr/local/bin/urchin/bin?
Or somewhere else? Is urchinctl a shell or perl script?
There is no actual urchin as far as I know. The control file is
/usr/local/urchin/bin/urchinctl. It is a executable file:
urchin# file /usr/local/urchin/bin/urchinctl
/usr/local/urchin/bin/urchinctl: ELF 32-bit LSB executable, Intel 80386,
version 1 (FreeBSD), statically linked, stripped
After running /usr/local/urchin/bin/urchinctl start, I have these
related processes:
urchin# ps acux | grep urchin

In your script command is path_to_urchinctl. rc.subr will look for a
process named urchinctl and a pidfile named urchinctl.pid. It appears
that neither will be found, so the script can't stop or restart the
processes, because it doesn't know the pid and therefore the process that
it needs to kill. That doesn't explain why it won't start the processes
though. I *think* you need to name the script urchin rather than
urchin-server, but I can't test that.
To fix the pid problem, rc.subr offers some optional statements that, with
the proper arguments, can overcome the problem. You'll have to read man
rc.subr and test it to figure out what works, but here's an example that
might work:
pidfile=/var/run/urchinwebd.pid
check_pidfile=${pidfile}
If that does work, your script should at least be able to report the
status (running or not). I'm assuming that, because root is running the
lowest numbered process, killing that process will kill all the children
as well.
