double modem woes

[smoothjohn]

I have too modems in a linux box which work fine on there own.

The problem comes when one is connected and I try to dial up with the other. I'm using simple ppp-on/off scripts and pppd and I get the following error in the log file.

21:52:28 pppd By default the remote system is required to authenticate itself
21:52:28 pppd (because this system has a default route to the internet)
21:52:28 pppd but I couldn't find any suitable secret (password) for it to use to do so.
21:52:28 pppd (None of the available passwords would let it use an IP address.)

Any help would be great. Thanks

Sounds like you have "defaultroute" in your /etc/ppp/options file, this a globle file for all connections. You need to move that to a /options.ttyS0 file for the first serial port. When you bring up the second interface it can't creat a second default route, that is a no no.

Ok I put the defaultroute command in the options.ttys0 file and that works, but if I put it in ttyS1 I get the same error obviously. If I take it out I can’t browse the web with just modem 2 connected.

So let us say I don’t use modem2 independently and I just add the defaultroute command to ttyS0, if I have both modems connected will Linux use modem2 if modem1 is in busy?

What I really what is double the bandwidth so if modem1 is receiving / sending flat out modem2 will kick in.

Thanks for the help at least now I know the problem.

Looking into channel bonding....
Sorry haven't played with that....
So I'm no help in that department.

do you have a "auth" in your options.ttyS1 file? That could be it. also, how are you connecting to your isp? a ppp dialer or pppd?
