Gotya....
cron jobs require fully qualified path unless you've set the path properly.

Thanks Neil,
I've got this bit working now.
My only problem at present is that my cron job isn't running and I'm not
sure why.
/me is back off to keep reading man cron
Cheers Don

did you sort all of this out in the end? i find that reading the shell
scripts in /etc/init.d teaches me how to do things in shell scripts.
i didn't see anyone give an example of "if" in a shell script, so if
you've not seen it yet:
if [ x1 == x`iptables -vL INPUT | grep banned2 | wc -l` ]; then
echo y;
fi
(the "x" in "x1" above is so that when the backtick command returns the
empty string, the shell interprets "if [ x1 == x ].." rather than "if
[ 1 == ]..", which is illegal. the "banned2" string above if what i'm
looking for the presence or absence of in the iptables output. "wc -l"
counts the lines in the output)

Good news! Last night, with the help of Tusker and Neil I got the
iptables stuff logging! :)
Bad news... I'm stuck again :)
I have two issues - GREP IN A SCRIPT, DO WHILE LOOP
GREP IN A SCRIPT
The question... how do I script a test?
if (iptables -L traffic_in -vn | grep "192.168.3.136") = "" then
iptables -A traffic_in -d $3
end if
(Yes, this is how I'd think of it in VB)
The problem... Duplicate records.
# iptables -A traffic_in -d $3
This creates a new counter every time the ip is refreshed by dhcp.
So I need to test to see if it's present.
I understand that I use grep, but I don't know how to code the syntax
to test it in a script.
# iptables -L traffic_in -vn
Gives me...
Chain traffic_in (13 references)
pkts bytes target prot opt in out source destination
9856 6879K all -- * * 0.0.0.0/0 192.168.3.136
0 0 all -- * * 0.0.0.0/0 192.168.3.136
0 0 all -- * * 0.0.0.0/0 192.168.2.130
7053 586K all -- * * 0.0.0.0/0 192.168.2.124
34918 35M all -- * * 0.0.0.0/0 192.168.3.183
Which as you can see has duplicate records for 192.168.3.136...
So at the command line I go ...
[EMAIL PROTECTED] shared]# iptables -L traffic_in -vn | grep
"192.168.3.136"
9856 6879K all -- * * 0.0.0.0/0 192.168.3.136
0 0 all -- * * 0.0.0.0/0 192.168.3.136
But how do I script this so I can use it in the batch file...
if (iptables -L traffic_in -vn | grep "192.168.3.136") = "" then
iptables -A traffic_in -d $3
end if
DO WHILE LOOP
Next I need to collect the traffic information into the database.
Sudoo code...
for each line in iptables -L traffic_in -vn
Ip = $8
Data = $2
mysql
-h bowenvale
-u oncs
-pbutterfly
-e "INSERT INTO oncs.tblData
(IPAddress, DataUsed)
VALUES('$Ip', '$Data');"
loop
From: http://forum.openwrt.org/viewtopic.php?pid=30841
[EMAIL PROTECTED] shared]# iptables -L traffic_in -vn | awk '{if
(int($1)!=0) print $8"\t"$2}'
192.168.2.124 33M
192.168.2.148 5140K
192.168.3.136 6879K
192.168.2.124 721K
192.168.3.183 35M
[EMAIL PROTECTED] shared]#
This is great, but how do I turn it in to a loop so I can stuff each
record into the database?
TIA
Cheers Don
