Upload that image every two seconds to an FTP share Against my better judgement, since I have some doubts that you really want to do this, here's how I would tackle this: 1. Do not use any scheduler whatsoever. 2. I'm assuming the FTP server is yours. Trying to log into somebody else's FTP server every 2 seconds goes beyond rude - it's offensive. 3. Write a perl script to do the get & put. Don't use wget but use the callable routines to get the file. Open a single FTP session and put the file regularly. Better yet would be to write a custom app to copy the file over, or even better would be to not copy the file over unless it's needed - either via nfs, smb, or something. Copying the same image every 2 seconds is a large waste of resources unless users are actually pulling that image off your FTP server every 2 seconds. 4. Do *NOT* try to log into the FTP server every 2 seconds to put a file. FTP isn't that efficient and doing a new login every 2 seconds is going to kill the FTP server. -- Ed Wilts, Mounds View, MN, USA mailto:ewilts@xxxxxxxxxx Member #1, Red Hat Community Ambassador Program -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
