Package: dpkg Version: 1.4.0.34 Severity: wishlist Given that I want to log any dns traffic on my ippp0 line. I have the following script in /etc/ppp/ip.d/dns-tcpdump:
|#!/bin/bash | |PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin |NAME="tcpdump-dns" |DAEMON="/usr/local/sbin/tcpdump" |PARM="-l -s 256 -vvv -i $PPP_IFACE udp port 53" | |case "$PPP_OPERATION" in | up) | logger -t $PPP_IFACE "starting tcpdump" | echo "logging DNS traffic on $PPP_IFACE" >> /var/log/dns-tcpdump | start-stop-daemon --start --quiet \ | --pidfile /var/run/$NAME.pid \ | --exec $DAEMON -- $PARM >> /var/log/dns-tcpdump & | logger -t $PPP_IFACE "started tcpdump with pid `cat /var/run/$NAME.pid`" | ;; | down) | logger -t $PPP_IFACE "killing tcpdump with pid `cat /var/run/$NAME.pid`" | start-stop-daemon --stop --quiet \ | --pidfile /var/run/$NAME.pid | echo "end log of DNS traffic on $PPP_IFACE" >> /var/log/dns-tcpdump | ;; |esac Since tcpdump doesn't create a pid file and start-stop-daemon treats the file it gets passed with --pidfile as a strict read-only file, this doesn't work since nothing actually creates the pid file. I believe that start-stop-daemon should have an option like --create-pidfile where it writes the pid of the newly started process to. This could be accomplished quite easily in the source while creating the pidfile in the shell script needs quite some effort.
