>Description:
When trying to do shell commands from /etc/ppp/ppp.linkup (to handle dynamic DNS issues), the ppp program fails to initiate a proper connection. The following is my ppp.linkup file as it stands now:
---------------
#
# ppp.linkup
# FG 20-V-2003
#
SBC_Yahoo:
# ! sh -c "/usr/scripts/linkup.sh"
# mail root w/ new IP
! sh -c "/sbin/ifconfig tun0 | /usr/bin/mail -s 'New IP' root"
# dynamic DNS
# ! sh -c "/usr/local/sbin/odsclient fgasper `/bin/cat /etc/ods-pw` operaman.ods.org"
# ! sh -c "/usr/local/bin/wget -O - --http-user=fgasper --http-passwd=GurgiKin 'https
://dynamic.zoneedit.com/auth/dynamic.html?host=fgmusic.org'"
# ! sh -c "/usr/local/bin/wget -O - https://www.sitelutions.com/dnsup?id=145690\&user
=fgasper@uiuc.edu\&pass=<password>\&ip=
---------------
An alternate form of the ifconfig line that I've used (and that makes ppp.linkup mess things up) is:
--------
! sh -c "/sbin/ifconfig tun0 | /usr/bin/grep inet | /usr/bin/awk '{print $2}' | mail -s 'New IP' root"
--------
Taking out the two middle commands clears up the problem. Also, running any external script (like the linkup.sh) seems to hose things as well.
>How-To-Repeat:
Configure /etc/ppp/ppp.linkup as I have it and run it in PPPoE mode w/ ddial.
