8. Multiple Configurations

I have not tested this, but it should be rather simple.

Note: rh-isdn-conf does not support multiple configurations right now (propably never will), so you have to make these changes always manually.

8.1. Modifications in /etc/ppp

First of all you have to either copy /etc/ppp/ippp0.d to eg. /etc/ppp/ipppX.d, X being one of the devices /dev/ippp[0-9]*.

8.2. Modifications in /etc/sysconfig/network-scripts

You have to copy /etc/sysconfig/network-scripts/ifcfg-ippp0 as well and adjust it to your needs.

Note: If you have a caching-only nameserver you have to alter named.conf or named.boot instead. You have to change the forwarder according to your IPS's name-server.

8.3. Modifications in /etc/isdn

Take a look at ippp0.conf and ippp1.conf, the first one is a sample for a master-device-, the second for a slave-device-configuration. Take a look at Section 4.3 to get the meaning of the settings.

Include your new ISP's number in callerid.conf.

8.4. More than one ISDN-card

Well, if all your cards use the hisax-driver it is rather simple: Just enter the parameters like IO, MEM etc. for all your cards seperated by a single comma in /etc/sysconfig/isdn like e.g.:

I4L_IO="0x0360,0x0400"
I4L_ID="Elsa%Teles"

The only exception is I4L_ID where the IDs have to be seperated by a %-(Percent)-sign. Thanks to Gerhard Sittig <Gerhard.Sittig@gmx.net> for his suggestions in this area.
