Hi again I did something similar on a RedHat system with modems hooked up to different telcos and ISPs some years ago. I no longer have the scripts to hand, but they were similar in consept to the example posted to this list under the thread 'Load Balancing / Redundant Network ?' today. I think I just set the default route off of the box, which in my case brought up the second PPP connection. I had one script constantly checking the status of the primary PPP line and one checking the status of the active line. The primary monitor would test the line every five minutes and switch to/from the secondary as necessary. There were some rules to not switch every five minutes in case the primary line was having a bout of intermittent problems. I think I left the secondary up for at least 30 minutes if ever it was switched to. The active monitor reported loss of the currently active line and what it was doing about it, especially if it was the secondard i/f and the primary was still flagged as failing. Is that the sort of thing you're looking for or do you need a 'proper' package? IanC -- [email protected] mailing list
