I need to stop a running service, then edit its run/conf file

[docJ]

Hello,

I recently installed CrashPlan (a backup program) on my new computer running Ubuntu 12.04 x64 desktop.

The initial backup has stopped when it reached around 40/45%, with a program specific error.
Googling it gave me this seemingly easy 2 steps solution: stop the service & edit one number in its run config file.
Being such a Ubuntu noob, I am uncertain how to stop the service, and therefore unable to edit the config file.

The how to fix is at: http://askubuntu.com/questions/12805...grade-to-12-04 (look for Christian Riedel's answer)

The how to stop the background engine service "recipe" is at the bottom of http://support.crashplan.com/doku.ph...ine?redirect=1

When I navigate to usr/local/crashplan/bin, I see the file "CrashPlanEngine", but then what am I supposed to do there?
I have 4 options: Run in terminal, Display, Cancel, and Run

First you need to navigate correct directory...

cd /usr/local/crashplan/bin

Then issue the stop command...

./CrashPlanEngine stop

I dont't know if I'm doing something wrong, here's the result:

jlr@ub3:~$ cd /usr/local/crashplan/bin
jlr@ub3:/usr/local/crashplan/bin$ ./CrashPlanEngine stop
Stopping CrashPlan Engine ... Still running, killing PID=19807 ... 
./CrashPlanEngine: line 150: kill: (19807) - Operation not permitted
OK
jlr@ub3:/usr/local/crashplan/bin$

Sorry, you need to run the command with root privileges...

sudo ./CrashPlanEngine stop

[docJ]

Stopping CrashPlan Engine ... Still running, killing PID=21293 ... 
OK

Thanks !
Now step2:
I need to go to: /usr/local/crashplan/bin/run.conf and edit a number, when I try with Nautilus I get a message its read only and I can't edit it. What do I type on the terminal to edit?

PS: Is it stopped for good (until I restart it only same way but with start instead of stop), or just rebooting would restart it, as far as you know?

[docJ]

OK, I managed by going gksudo nautilus, I was then able to edit the file.
I will restart the service and see if I got rid of my program error...

[docJ]

I think doing it with gksudo was not good, I now have an edited run.conf file and next to it a run.conf.save that seems a copy of the original unedited file

[docJ]

I compared the files, they were identical but for the single edited number (and file name)
I have deleted the (copy) run.conf.save and all is well

Thanks for now, I have to increase number a bit, try again, if no joy: increase a bit again and try again, and so on...
