firewall for slack 14

4436 · 10-20-2012, 11:36 AM

I have a firewall script that I have been using for several slackware distributions. When I upgraded to slack 14 it locked me out of the internet. My system is:
eth0 connects to the internet
eth1 connects to a router which my wife's computer (WINXP) uses to get to the internet.
You can download (but not read online) my rc.firewall here:

Right now I am running w/o a firewall so I would like to fix this situation. If you have a suggestion about what is wrong with my script of if you have a suggestion about a new script I would be grateful.
Thanks.

Use Alien Bob's Firewall Generator: http://www.slackware.com/~alien/efg/index.php

I had the same problem.
The output from 'ifconfig' has a slightly different format in Slackware 14. This causes a problem in this line.

EXTIP="`$IFCONFIG $EXTIF | $AWK \
/$EXTIF/'{next}//{split($0,a,":");split(a[2],a," ");print a[1];exit}'`"

I am now using this.

Code:

EXTIP="$($IFCONFIG $EXTIF | $GREP -w inet | $AWK '{print $2;exit}')"

Thanks, on the advice of others I switched to a firewall generator found at http://www.slackware.com/~alien/efg/.
