- by Binh Nguyen
my server down random every day 4-5 time cause get high load very quick..
I have install csf and with some config server now stable.. load around 5.
BUT the big isuse is : the real user very hard to access website specially from IE browser
you can test at xaluan.com
the flowing is config using in csf:
SYNFLOOD = "1"
SYNFLOOD_RATE = "100/s"
SYNFLOOD_BURST = "10"
CONNLIMIT = "80;30"
PORTFLOOD = "80;tcp;70;5"
CT_LIMIT = "29"
# other config may same as default
i playing around with this config for a week but still not work around..
If increase the rate SYNFLOOD_RATE = "140/s" or more.. the website response very fast.. be side have bad effect of server load increase so fast normal 20 and may be up to few hundred in peck time ..
my need is response time fast but load still low..
