Hello,

I would like to auto execute a script when the openvpn connection goes down to automatically unmount the sshfs share that is accessible only through the vpn.

So I have put in my config in /etc/openvpn/myconf.ovpn:
Code:
script-security 2
up /etc/openvpn/maemo-update-resolvconf
plugin /opt/openvpn/lib/openvpn/openvpn-down-root.so "script_type=down /etc/openvpn/maemo-update-resolvconf"
And in /etc/openvpn/maemo-update-resolvconf:
Code:
#!/bin/bash
#
# Parses DHCP options from openvpn to update resolv.conf
# To use set as 'up' and 'down' script in your openvpn *.conf:
# up /etc/openvpn/maemo-update-resolvconf
# plugin /opt/openvpn/lib/openvpn/openvpn-down-root.so "script_type=down /etc/openvpn/maemo-update-resolvconf"
# Customized version for Maemo (lacks resolvconf)
# 02.08.2009 andrea@borgia.bo.it

# and Chris Hanson

#
# Example envs set from openvpn:
# foreign_option_1='dhcp-option DNS 193.43.27.132'
# foreign_option_2='dhcp-option DNS 193.43.27.133'
# foreign_option_3='dhcp-option DOMAIN be.bnc.ch'
#

case $script_type in

up)
    for optionname in ${!foreign_option_*} ; do
	option="${!optionname}"
	echo $option
	part1=$(echo "$option" | cut -d " " -f 1)
	if [ "$part1" == "dhcp-option" ] ; then
	    part2=$(echo "$option" | cut -d " " -f 2)
	    part3=$(echo "$option" | cut -d " " -f 3)
	    if [ "$part2" == "DNS" ] ; then
		IF_DNS_NAMESERVERS="$IF_DNS_NAMESERVERS $part3"
	    fi
	    if [ "$part2" == "DOMAIN" ] ; then
		IF_DNS_SEARCH="$part3"
	    fi
	fi
    done
    R=""
    if [ "$IF_DNS_SEARCH" ] ; then
	R="${R}search $IF_DNS_SEARCH\n"
    fi
    for NS in $IF_DNS_NAMESERVERS ; do
	R="${R}nameserver $NS\n"
    done
    if [ ! -f /etc/resolv.conf.prevpn ] ; then
	mv /etc/resolv.conf /etc/resolv.conf.prevpn
    fi
    echo -e "$R" > /etc/resolv.conf
    ;;

down)
    if [ -f /etc/resolv.conf.prevpn ] ; then
	mv /etc/resolv.conf.prevpn /etc/resolv.conf
    fi

    /etc/openvpn/myscript
    ;;

esac

My script to unmount the sshfs share works great when triggered manually, but when triggered automatically by the maemo-update-resolvconf, it doesn't have the time to finish executing.

The script:
Code:
LOCALDIR=/home/user/MyDocs/Lan/Server
	REMOTEDIR=/home/user/
	USER=user
	SERVER=myip
	VAR="`mount | grep $LOCALDIR`"

		if [ -n "$VAR" ]
		then
			PING="`ping -q -c 1 $SERVER > /dev/null 2>&1`"
			if [ $? -eq 0 ]
			then
				echo "Unmount SSHFS Server"
				umount $LOCALDIR/
				echo "Off"
			else
				run-standalone.sh dbus-send --type=method_call --dest=org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.Notifications.SystemNoteDialog string:"SSHFS: $SERVER doesn't respond to ping. Please verify the connection before unmounting." uint32: string:
			fi
		fi
So when executed automatically, I always get the message "SSHFS: $SERVER doesn't respond to ping. Please verify the connection before unmounting.", but if I execute the script with an active openvpn connection, the share unmounts without any issue. I therefore think that the openvpn connection disconnects too quickly and the script doesn't have the time to finish executing.

MY QUESTION: How to delay the openvpn disconnect so that the script finishes executing? (I have tried a "sleep 10" in maemo-update-resolvconf after "/etc/openvpn/myscript" but it doesn't help.

Thank you.
