I have a little problem in here. Actulay i think, that bash doesn't caount good, look: cat bin/users | wc -l 1877 so the file contains 1877 lines cat bin/users: #!/bin/sh /sbin/ipfw -q delete 2001 >/dev/null 2>&1 & /sbin/ipfw -q add 2001 count ip from 192.168.0.1 to not me in via fxp0 >/dev/null 2>&1 & /sbin/ipfw -q delete 2002 >/dev/null 2>&1 & /sbin/ipfw -q add 2002 count ip from not me to 192.168.0.1 out via fxp0 >/dev/null 2>&1 & /sbin/ipfw -q delete 2003 >/dev/null 2>&1 & /sbin/ipfw -q add 2003 count ip from 192.168.0.111 to not me in via fxp0 >/dev/null 2>&1 & /sbin/ipfw -q delete 2004 >/dev/null 2>&1 & /sbin/ipfw -q add 2004 count ip from not me to 192.168.0.111 out via fxp0 >/dev/null 2>&1 & ***** **** ***** **** **** **** /sbin/ipfw -q add 2935 count ip from 192.168.5.63 to not me in via fxp0 >/dev/null 2>&1 & /sbin/ipfw -q delete 2936 >/dev/null 2>&1 & /sbin/ipfw -q add 2936 count ip from not me to 192.168.5.63 out via fxp0 >/dev/null 2>&1 & /sbin/ipfw -q delete 2937 >/dev/null 2>&1 & /sbin/ipfw -q add 2937 count ip from 192.168.5.99 to not me in via fxp0 >/dev/null 2>&1 & /sbin/ipfw -q delete 2938 >/dev/null 2>&1 & /sbin/ipfw -q add 2938 count ip from not me to 192.168.5.99 out via fxp0 >/dev/null 2>&1 & so I should have 938 rules in my firewall. 938 * 2=1876 + 1 = 1877 lines in the script (1 rule for delete rule and one for add rule + rule at the top '#!/bin/sh') but when adding this rules to the ipfw ruleset i have: ipfw show 2000-2938 | wc -l 809 so somehere my 938-809=129 rules had just gone somewhere. I'm using bash in here.. could that be a bug in bash ? bash --version GNU bash, version 2.05b.0(1)-release (i386-portbld-freebsd4.9) btw, when i look into ipfw and can't find some rules in it.. for example there goes rule nr 2001,2002,2003,2004,2005,2008 so i have no rule with number 2006 and 2007 but they exist in my script. after running this script other time i got ipfw show 2000-2938 | wc -l 814 one more time : ipfw show 2000-2938 | wc -l 836 But I have not changed anything in my script. -- Best regards,Hugle
