Hello,
I had tried the userppp from pkgsrc but didn't succeed. So I
installed one from http://www.awfulhak.org/ppp.html (ppp-030706).
With this one I'm able to establish a single connection via isdnd.
ifconfig of tun0 is:
tun0: flags=80f5<UP,DEBUG,POINTOPOINT,NOTRAILERS,RUNNING,NOARP,MULTICAST> mtu 1500
inet 10.0.0.1 -> 10.0.0.2 netmask 0xfffffffc
If I'm trying to establish a setup with bundled channels tun0 gets
the loopback flag:
tun0: flags=a079<UP,LOOPBACK,POINTOPOINT,NOTRAILERS,RUNNING,LINK1,MULTICAST> mtu 1500
inet 127.0.0.1 -> 10.0.0.2 netmask 0xffffff00
The entry in ppp.conf is:
set cd 20
set phone 100000
set device /dev/isdnbchan0 /dev/isdnbchan1
set login
set authname name
set authkey key
set timeout 178
set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
disable loopback
set mrru 1524 # Multilink mode please
set mru 1504 # Room for the MP header
clone 1,2 # Two new links
link deflink rm # And get rid of the original one
link * set mode auto # Automatically manage the second link
set autoload 2 50 130 # Down @5% usage, up at 50%, 30s sample
How can I remove the loopback flag from tun0 in the bundled setup?
