I'm close to finishing a shell script to automatically enable the DMZ
on my Linksys router no matter what IP address my computer has.
This returns the last octet of my local IP address, which happens to be
a "5":
ifconfig | grep netmask | grep -v 127.0.0.1 | awk {'print $2'} | sed
's/10.1.1.//'
This connects to the web interface of my Linksys router to turn on the
DMZ: (notice the "5")
curl -u admin:password -d
"submit_button=DMZ&change_action=&action=Apply&dmz_enable=1&dmz_ipaddr=5
" -s http://10.1.1.1/apply.cgi
How do I connect the two commands?
Piece of cake. Use the backquotes to grab the first command's output:
LAST_OCTET=`ifconfig | grep netmask | grep -v 127.0.0.1 \
| awk {'print $2'} |sed 's/10.1.1.//'`
curl -u admin:password -d \
"submit_button=DMZ&change_action=&action=Apply&dmz_enable=1&dmz_ipaddr=$LAST_OCTET"\
-s http://10.1.1.1/apply.cgi
Even so, this seems really hacky (in a bad way). For example, you can pass
an interface name to ifconfig- call "ifconfig eth0" instead of greping out
the localhost IP.
