Some additional information for setting up a syncPPP
|
|
connection using network interfaces.
|
|
---------------------------------------------------------------
|
|
|
|
You need one thing beside the isdn4linux package:
|
|
|
|
a patched pppd .. (I called it ipppd to show the difference)
|
|
|
|
Compiling isdn4linux with sync PPP:
|
|
-----------------------------------
|
|
To compile isdn4linux with the sync PPP part, you have
|
|
to answer the appropriate question when doing a "make config"
|
|
Don't forget to load the slhc.o
|
|
module before the isdn.o module, if VJ-compression support
|
|
is not compiled into your kernel. (e.g if you have no PPP or
|
|
CSLIP in the kernel)
|
|
|
|
Using isdn4linux with sync PPP:
|
|
-------------------------------
|
|
Sync PPP is just another encapsulation for isdn4linux. The
|
|
name to enable sync PPP encapsulation is 'syncppp' .. e.g:
|
|
|
|
/sbin/isdnctrl encap ippp0 syncppp
|
|
|
|
The name of the interface is here 'ippp0'. You need
|
|
one interface with the name 'ippp0' to saturate the
|
|
ipppd, which checks the ppp version via this interface.
|
|
Currently, all devices must have the name ipppX where
|
|
'X' is a decimal value.
|
|
|
|
To set up a PPP connection you need the ipppd .. You must start
|
|
the ipppd once after installing the modules. The ipppd
|
|
communicates with the isdn4linux link-level driver using the
|
|
/dev/ippp0 to /dev/ippp15 devices. One ipppd can handle
|
|
all devices at once. If you want to use two PPP connections
|
|
at the same time, you have to connect the ipppd to two
|
|
devices .. and so on.
|
|
I've implemented one additional option for the ipppd:
|
|
'useifip' will get (if set to not 0.0.0.0) the IP address
|
|
for the negotiation from the attached network-interface.
|
|
(also: ipppd will try to negotiate pointopoint IP as remote IP)
|
|
You must disable BSD-compression, this implementation can't
|
|
handle compressed packets.
|
|
|
|
Check the etc/rc.isdn.syncppp in the isdn4kernel-util package
|
|
for an example setup script.
|
|
|
|
To use the MPPP stuff, you must configure a slave device
|
|
with isdn4linux. Now call the ipppd with the '+mp' option.
|
|
To increase the number of links, you must use the
|
|
'addlink' option of the isdnctrl tool. (rc.isdn.syncppp.MPPP is
|
|
an example script)
|
|
|
|
enjoy it,
