Very Computer

I am using a leased line to connect 2 linux server with ppp.
The command line is /usr/sbin/pppd /dev/ttyC0 38400
192.9.201.20:192.9.201.21 persist

the remote server is/was redhat 6.0

The local was redhat 5.2 with the option 'passive'

Now, I upgraded to 7.1 and when I try to shut the server down, it fails on
killing the ppp connection (and hangs before unmounting the disks ...)
At the Killall action, he cut the lines, but they connect again 5 sec later
...

any ideas ? of course I could remove the 'persist' option, but in case of
phone line failure, I need the modem AND the ppp the reestablish the
connection automatically.

thanks for help,

xavier.

Put a K05ppp file in /etc/rc.d/rc6.d which will close down the ppp link
on shutdown.
Ie, this file should issue a killall pppd.
killing pppd should not allow the persist to work, since it is pppd that
does the persist option and it is dead. Or did you put pppd into
/etc/inittab or something like that?

If i kill the process one by one using the pid : no problems.

any idea ?

]When I issue a killall pppd or killall -HUP pppd, the connections goes down

]...)

Well,I sure would not use -HUP as that is hangup which ppp interprets as
teh modem having lost connection. killall pppd will kill it but it will
run its closedown routines first. do youhave something there?
Do you have something in /etc/inittab regarding ppp?

]If i kill the process one by one using the pid : no problems.

How?

]any idea ?

Why in the world would you have 5 pppd running. One will handle all the
traffic between the two machines fine. Why 5?

]Because I have 5 modem with 5 leased lines connecting to 5 different servers
]...
]anyway, how could i kill them softly ?

Write a root script which does kill to each of the ppp in turn, and then running
halt  or shutdown -h.
I can see no reason why killall pppd would not work, but you say it does not, so
shut them down one at a time.

#!/bin/bash
for i in `pidof pppd`
do
kill $i
sleep 1
done
shutdown -h now
