RE: [Samba] start of print file spool to samba
oh. that's what you meant.
i was thinking that a jni/rmi call would be much, much faster. but this is
easiest to code.
i'll do it.
thanks for helping me see the forest. i was concentrating on the trees.

Why not just make your command a wrapper that executes the lpr command?
Something like
#!/bin/sh
my_command $1
lpr -P$2 $3
/bin/rm -f $3
and add a print command = some_script.sh %I %p %s
No code changes necessary.

RE: [Samba] start of print file spool to samba
oops. on second thought, i take it all back. this won't do at all.
i want to get control at the very beginning of spooling the print job from
the client machine to samba, not when samba is ready to print the job. i
want to hook into samba as close to the point when samba realizes that it is
going to receive a print job from the client machine as i can. and, at that
hook location, i need to be able to easily get the client machine's ip
address.

it looks like this routine is the place? see my comments in the routine
body.

DEBUG(3,(Running the command `%s' gave %d\n,syscmd,ret));
return ret;
}
does this look right to you?
now the problem is: i need the ip address of the client that submitted the
print job. how do i get that?

Look for where we execute the print command.

[Samba] samba and JNI
i am using a linux/sambabox as a print server. whenever a user submits a print job, i want to notify the user that samba is receiving the print job. i have a java service running on each client machine that pops up a gui to that effect when notified. i am trying to integrate java JNI into samba to tell the java server on the client to display the gui. however, just adding the JNI initialization code to "smbd/server.c main" causes samba to get the following error whenever a print job is submitted. also, the print job fails to spool.
