Restrict Print queue access

Luis Toro — Tue, 01 Nov 2005 16:54:54 GMT

Is there a way to restrict the use of a print queue to only a certain subset of users on an HPUX system ?
Thank you

While some versions of the System V spooler allow a -u allow:login_list or a -u deny:login_list lpadmin option, HP-UX's implementation does not. You might consider another spoller package like CUPS.

There is a way to do this using the standard spooler. The interface file is supplied with the user as the $2 parameter. It would be rather easy within this interface file (which is just a shell script) to search a file for the existence (or non-existence) of this user and continue or simply exit with a non-zero status.

As Clay points out, each printer has a unique printing script and you can not only test for specific users (and exit with a non-zero code for disallowed users) but you can even test the size of the print job. Although the3 scripts are lengthy, the getting-started section is fairly simple.

Thank you both. I suspected this ot be the case, but I wanted to be sure.
Bill, you mentioned 3 scripts. I know the interface script, and the corresponding script under the model.orig subdirectory. Which is the 3rd, and which should I modify ?
thanks again

One other point: You non-zero exit status should be in the range 1-127 so that the printer will not be disabled.

Oops, that was a defective keyboard--ignore the 3. The model.orig scripts are for JetDirect printers while the scripts in the parent directory that specify parallel or serial printers would be the ones to modify.
