Hi,
I am trying to load balance two squid cache server which is installed
Freebsd 6.2. And my ldirectord is running in FC 6 with fwmark table.
my ldirectord.cf file
--------
# Prepared: April 2005
# Global Directives
checktimeout=10
checkinterval=2
#fallback=127.0.0.1:80
autoreload=no
#logfile="/var/log/ldirectord.log"
logfile="local0"
quiescent=no
# Note: persistancy needs to be turned on if FTP traffic is to handled
# using LVS-DR (gate) or LVS-TUN (ipip). This is not neccessary
# or LVS-NAT (masq).
virtual=1
real=202.xx.xx.1:3128 gate
real=202.xx.xx.2:3128 gate
service=http
checkport=3128
checktype=connect
protocol=fwm
request="http://yahoo.com";
# receive="Test Page"
scheduler=dh
#persistent=600
----------------------------------------
/sbin/iptables -t mangle -A PREROUTING -p tcp --dport 80 -j MARK
--set-mark 1
ip rule add prio 100 fwmark 1 table 100
ip route add local 0/0 dev lo table 100
-------------------------------------------------------
While checking with showtraffic scripts I am sometimes getting 18K
packets/s which I don't think it shoud because I have only 100 user.
while checking in mrtg both server proxy and lvs interface traffic
increase from 400kbits to 9mbits. This high traffic is only in cache
server where as another cache run as normal. Is this DOS attack or
ldirectord bug. I am using ldirectord 2.0.8 with ipvsadm 1.24.
