Hi again |

I did something similar on a RedHat system with modems hooked up to |
11 |
different telcos and ISPs some years ago. I no longer have the scripts |
12 |
to hand, but they were similar in consept to the example posted to this |
13 |
list under the thread 'Load Balancing / Redundant Network ?' today. |
14 |
|
15 |
I think I just set the default route off of the box, which in my case |
16 |
brought up the second PPP connection. I had one script constantly |
17 |
checking the status of the primary PPP line and one checking the status |
18 |
of the active line. |

The primary monitor would test the line every five minutes and switch |
21 |
to/from the secondary as necessary. There were some rules to not switch |
22 |
every five minutes in case the primary line was having a bout of |
23 |
intermittent problems. I think I left the secondary up for at least 30 |
24 |
minutes if ever it was switched to. |
25 |
|
26 |
The active monitor reported loss of the currently active line and what |
27 |
it was doing about it, especially if it was the secondard i/f and the |
28 |
primary was still flagged as failing. |

Is that the sort of thing you're looking for or do you need a 'proper' |
31 |
package? |
