Jelikoz statistiky Sosacu byli po padu iGW - Oriona zruseny/vypnuty/znova nenahozeny: http://charon.hkfree.org/~pavkriz/hkfree/stat.php

tak jsem se rozhodl ze bych si neco podobneho mohl pustit na APckach abych mel prehled kdo jak moc sosa. Sic by nekdo mohl namitnout, ze muzu pouzit RRD Tools, ale ty zatezujou system opravdu neskutecnym zpusobem, coz je neprijatelne a tak se to pokusim udelat jinak s tim ze to sice nebude graficky zobrazovano pres hotsanic (coz me netrapi) ale bude se to tahat z MySQL databaze.

Prvni cast scriptu, kterou jsem za asistence Coudka dal do kupy, je tato:

## Pokud vam bezi take na AP shaper, tak to musiste tahat odsud

iptables -nL -t mangle -vx | grep eth1 | grep all | awk '{ if ($3 !="IMQ") {print $2 " " $8 " " $9}}' | cat > /root/data-frafic/users-data.tmp

## Pak se to tridi na download a upload

cat /root/data-frafic/users-data.tmp | awk '{ if ($2 !="0.0.0.0/0") {print $1 " " $2}}' | cat > /root/data-frafic/users-data.upload cat /root/data-frafic/users-data.tmp | awk '{ if ($3 !="0.0.0.0/0") {print $1 " " $3}}' | cat > /root/data-frafic/users-data.download

## Prevod do formatu MySQL

cat /root/data-frafic/users-data.upload | awk '{print "INSERT INTO `upload` ( `bytes` , `IP` ) VALUES ( '"'"'"$1"'"'"' , '"'"'"$2"'"'"' )" ";" }' | cat > /root/data-frafic/mysql-upload.sql cat /root/data-frafic/users-data.download | awk '{print "INSERT INTO `download` ( `bytes` , `IP` ) VALUES ( '"'"'"$1"'"'"' , '"'"'"$2"'"'"' )" ";" }' | cat > /root/data-frafic/mysql-download.sql

## Upload do MySQL databaze

mysql -u uzivatel_db --password=heslo_do_db -D databaze < /root/data-frafic/mysql-upload.sql mysql -u uzivatel_db --password=heslo_do_db -D databaze < /root/data-frafic/mysql-download.sql

Pokud by mel nekdo napad jak cokoliv vylepsit, zjednodusit ci zprehlednit necht klidne da vedet treba na newsech

Co je potreba dodelat

1. Pricitani hodnot ke stavajicim aby tabulka v MySQL nemela behem dne milion radku
2. Ukladani hodnot do nejakyho externiho souboru aby v pripade rebootu masiny, ci jen vymazani a znovu nahrani iptables pocitadlo nepocitalo odzacatku
