I have looked at the source and I have a question. In your init script you have ./${EXE_NAME} > output & where the & is apparently how you're trying to make it a background process.
From the INSTALL file:
•
•
•
•
Running Monkey
==============

bin/monkey

or

bin/monkey -D (to run monkey in background mode)
Shouldn't you be using -D to put it in Daemon/background mode instead of using &? Also your redirect only handles stdout but not stderr, and if something isn't initializing properly it will probably write to stderr. It should look like: ./${EXE_NAME} >> output 2>&1 & . Using ">" overwrites the file if it exists, or creates a new file where ">>" appends or creates a new file so your log will keep growing.

  100. root@localhost:/etc#

Btw the script I gave in post #1 works fine to start up a c++ exe I've written myself if it means I don't have to use the SKELETON one you suggested.

No idea, I didn't write the script. Can you update the script with what you think it should be and I'll try it with that.

Thanx for you help so far!

That output tells me that your init script is referenced in runlevels 0 (halt) and 3 (depends on distro). What distro is that machine running?

"Standard": 3 Multi-User Mode with Networking Starts the system normally
Debian: 2-5 are same
Redhat: Multi-User mode, console logins only
SuSE: 3 Multi-User mode, console logins only
Slackware: 3 Multi-User mode without display manager

So depending on what distro you're using that may be the wrong runlevel. One way of finding the distro:
text Syntax (Toggle Plain Text) 
  1. sk:/etc# find /etc -maxdepth 1 -iname \*rel\* ; find /etc -maxdepth 1 -iname \*ver\*
  2. /etc/squirrelmail
  3. [COLOR="Red"]/etc/debian_version[/COLOR]

I think redhat creates /etc/redhat-release .. but most all distros have a file named "release" or "version" in /etc.

Erm I vaguely remember the guy saying something about using linux from scratch? Does that matter?

I mean if that makes things a bit more easier.


I'll forget that for the time being and just try to get this working at start up for ubuntu as a vmware image?

But I really need this to work on start up.

Ok.. try this. kill the httpd, backup your file, replace it with this, and see if it starts. If it starts OK then try rebooting the machine.

After the machine reboots examing the contents of the log file and see if it even tried to execute. If it didn't execute then we'll add it to the other standard startup runlevels.

Ok I just tried that new script, but it didn't work.

The webpage still failed to load.


[edit]
Out of interest does it work on your machine.

To see it working you should be able to open your webbrowser, type in: localhost:2001

And it should server out the web page.

in order to start the exe manually, you go to

Shell Scripting Syntax (Toggle Plain Text) 
  1. > cd monkey-0.9.2
  2. > cd bin
  3. > ./banana restart

This is of course after you've ran the config and make file.

There could be a million things going wrong with the distro being LFS. Up for doing a gotomeeting or logmein and I can take a look at it? That would be the easiest way

With the new script is the daemon running? What does the contents of /root/monkey-0.9.2/bin/output have? Take a look at it: tail -50 /root/monkey-0.9.2/bin/output

wait a minute.... you're running ./banana but the script you posted earlier references a different file:
Shell Scripting Syntax (Toggle Plain Text) 
  1. EXE_DIR="/root/monkey-0.9.2/bin/"
  2. EXE_NAME="monkey"

Those are running two different files in the bin directory .. unless they're symlinked to eachother?

[edit]
I don't know if it will work on my machines. It requires a ton of libs that I don't have installed.

The output is:

Shell Scripting Syntax (Toggle Plain Text) 
  1. root@localhost:~/monkey-0.9.2/bin# more output
  2. Monkey HTTP Daemon 0.9.2
  3. Built : Aug  9 2009 22:38:40
  4. Home  : http://monkeyd.sourceforge.net

Which is probably useless no doubt.

Again, have you tried getting it to work for your linux distro.

If you can get it to run at start up that would be encouraging.

Not sure how to do the logmein. Is it something you gotta pay for?

Thanx again.
