After much struggle I've got myself a nicely working 64k connection,
but like very many before me MPPP has me beat! I found the ISDNUTILS
scripts and docs impenetrable, and came up with scripts based on a
couple of HOWTOs I came across.
This is my script to configure the connection:
MYUSER=robinsc
REMNAME=demon
MYIP=158.152.143.92
REMIP=158.152.1.222
MYMSN=1925xxxxxx
REMMSN=08440416672
/sbin/isdnctrl verbose 3
/sbin/isdnctrl system on
/sbin/isdnctrl addif ippp0
/sbin/isdnctrl eaz ippp0 $MYMSN
/sbin/isdnctrl addphone ippp0 out $REMMSN
/sbin/isdnctrl huptimeout ippp0 90
/sbin/isdnctrl l2_prot ippp0 hdlc
/sbin/isdnctrl l3_prot ippp0 trans
/sbin/isdnctrl encap ippp0 syncppp
/sbin/isdnctrl dialmode ippp0 auto
/sbin/isdnctrl addslave ippp0 ippp1
/sbin/isdnctrl pppbind ippp1 1
/sbin/isdnctrl eaz ippp1 $MYMSN
/sbin/isdnctrl addphone ippp1 out $REMMSN
/sbin/isdnctrl huptimeout ippp1 90
/sbin/isdnctrl l2_prot ippp1 hdlc
/sbin/isdnctrl l3_prot ippp1 trans
/sbin/isdnctrl encap ippp1 syncppp
/sbin/isdnctrl dialmode ippp1 auto
/sbin/ifconfig ippp0 $MYIP pointopoint $REMIP
/sbin/route add default netmask 0 ippp0
/sbin/ifconfig ippp0 -arp -broadcast
/sbin/ipppd user $MYUSER remotename $REMNAME \
$MYIP:$REMIP name $MYUSER \
-detach mru 1500 mtu 1500 lcp-restart 1 +mp debug \
/dev/ippp0 /dev/ippp1 &
To dial I issue:
isdnctrl dial ippp0
isdnctrl addlink ippp0
Both channels dial and connect, the problem lies when the slave
receives the IP from the host, it terminates with a "sifaddr failed"
error. The debug trace shows the master successfully negotiated MPPP.
I figure this means "set interface address" and refers to the fact
that since I have a static IP it's trying to set interface ippp1 to
the same IP as the master on ippp0.
I'm tried reading and re-reading HOWTOs, READMEs etc <sigh>, can
someone point out where I've gone wrong? It seems to me that I'm
"that close" to getting it going.
TIA,
Robin Collins
