How to replace old ip with new ip in ipsec.conf?


I have dialup connection with dynamic ip address, i want to replace the old ip address with the new ip address in the ipsec.conf which is in the 18th line:
Quote:
left=118.23.67.21
This is a code the print the new external ip address with each dialup connection:
Quote:
EXTIF="ppp0"
IFCONFIG=/sbin/ifconfig
AWK=/usr/bin/awk
EXTIP="`$IFCONFIG $EXTIF 2>/dev/null | $AWK \
/$EXTIF/'{next}//{split($0,a,":");split(a[2],a," ");print a[1];exit}'`"
echo "$EXTIP"
how to use a code with one of cat, echo or sed commands to replace the above line with the ouput of this new ip address?

Hey there, if I'm not mistaken, just entering this should work

Quote:
su -
(password you the Root, or your password, if you're in the sudorers)
nano /pathto/ipsec.conf
and edit, save and you're done...

Just a suggestion

Thor
