Date: Wed, 30 Mar 2005 10:46:06 -0500 From: Chuck Haines <chaines(a)gmail.com> Thanks to everyone's help, but I've figured out the backend stuff and written my own perl script that does the accounting using mysql. It's actually really neat and incredibly easy to use. I'm in the process of refinining it a bit now and if anyone is interested in it, I'd be more than happy to send it your way. It uses snmp to query the pages from the printer so it actually determines the number of pages printer and not just how many should have printed. So you have a network printer that can report that kind of thing. I guess I'm used to thinking of cheap, dumb inkjet printers.

Re: [Wlug] Cups help

Since there seems to be a decent bit of interest in this script, I'll post when my release version 0.2 today. For anyone who is interested check out http://gforge.maxslack.com/projects/cupsacct/. It's my personal project site and I have put up the first release. I'll be releasing the files here so it's the best way to get them. Not all the components of the project site are working yet (mostly web based CVS) but you can download the release tarball if you are interested. Also note that this script is still heavily modified for specific use in the ECE databases. I'm working on changing it so that it will be more universal and include sql to create the database and tables.

Short of rebuilding the kernel without the usb-storage support... Isn't there a script that runs vmware? Can't you just put the rmmod command in there? Or just write a new script that runs during rc1 or rc0 to run rmmod? -J On Wed, 30 Mar 2005 11:23:44 -0500, Andrew Robert <arobert(a)townisp.com> wrote: > Hi Everyone, > > I have a 160G NTFS partitioned USB external disk drive that I would like > to use in my VMware instance. > > I tried to get VMware to recognize the drive but it failed to do so > because the Linux USB driver had it locked. > > Removing and re-attaching the drive did not release the driver lock. > > What resolved the problem was to unload the usb-storage kernel module > using the command: > > /sbin/rmmod usb-storage > > This works great but the module reappears the next time I boot the > beast. > > Does anyone know of a way to make this permanently go away? > > Any help you can provide on this would be greatly appreciated. > > Thank you, > Andy > _______________________________________________ > Wlug mailing list > Wlug(a)mail.wlug.org > http://mail.wlug.org/mailman/listinfo/wlug >
