Hi all,
I seem to have come across a rather serious problem, I'm not sure whether
it's something in my setup or it's a bug in ppp.
I am using a very recent version downloaded today - ppp-990809.src.tar.gz.
Is this a day-to-day snapshot or have I just happened to come along when a
stable version has been released? I'm using the recent version as the one
supplied with 2.2.8R doesn't support multilink.
Anyway, the problem is that when running as a server (started with
'/usr/sbin/ppp -direct mp'), ppp doesn't seem to exit properly when
carrier is lost. There's nothing suggesting it actually detects the loss
of CD when I pull the (line) plug on the modem, and about 3 minutes later
it complains about the lack of response to LQR packets and declares the
bundle dead. However, the ppp task associated with that serial line
doesn't exit! It's still sitting there 20 minutes later, with 'who' still
showing up the login as if the modem was still connected. Meanwhile the
dialin line is just ringing out as obviously mgetty isn't running. To
regain control I have to log in via shell and kill off the ppp process.
This also happens if I kill -TERM the originating ppp (I presume this is a
graceful shutdown, with the originating end politely reporting it's about
to disconnect):
13285 ?? Is 0:00.01 /usr/sbin/ppp -direct mp
14815 ?? Ss 0:00.10 /usr/sbin/ppp -direct mp
System at both ends is running 2.2.8-RELEASE, here are the basic config
files...
<<<<client>>>> 'ppp -auto mp'
mp:
set timeout 0
set log phase chat
set dial "ABORT BUSY ABORT NO\sCARRIER TIMEOUT 5 \
\"\" ATZ OK ATDT\\T TIMEOUT 45 CONNECT \"\" ogin: sbruns word: 12345"
set redial 30+30-20 0
set reconnect 30 5
set login
set ifaddr 203.20.114.195/0 10.0.0.2/0
set authname ppp
set authkey ppppassword
set mrru 1500
set enddisc label
enable lqr
accept lqr
clone 1,2
link deflink remove
link 1,2 set mode ddial
link 1 set phone "93291234"
link 2 set phone "93291234"
link 1 set device /dev/cuaa1
link 2 set device /dev/cuaa2
link 1 set speed 115200
link 2 set speed 115200
<<<<server>>>> 'ppp -direct mp' from shell script run after normal login
mp:
allow user sbruns
allow mode direct
set openmode active
set timeout 0
set log phase chat
open
set login
set ifaddr 203.20.114.32/0 10.0.0.2/0
set authname ppp
set authkey ppppassword
set mrru 1500
set enddisc label
enable lqr
accept lqr
clone 1,2
link deflink remove
Note that I'm generally unfamiliar with user level PPP, so the basic
config is from the man page and I haven't started tweaking things yet. I
haven't bothered to set up PAP/CHAP because the chat script logs in via
the login/Password prompt before starting up ppp.
Thanks for any help. :-(
Cheers.
