Kepanjangan di atas bisa dibilang, Tidur Tak Nyenyak Makan Tak Kenyang. Itu mungkin tanda-tanda stress (termasuk penulis “stress-red”).

Stickies from centos.org/

exclude domain in modsec

Using Apache/2.2.11 PHP 5.2.9 (cPanel) and mod_security2.

add this line after default action.
SecRule SERVER_NAME "yourdomain0.com" phase:1,nolog,allow,ctl:ruleEngine=off
SecRule SERVER_NAME "yourdomain1.com" phase:1,nolog,allow,ctl:ruleEngine=off

file size routing table

Kurang kerjaan nganalisa bgp v4 RoS.

[agusr@rr.bgp]
[agusr@rr.bgp] /ip route pr count-only
296607
[agusr@rr.bgp] /ip route print detail file=route.txt
[agusr@rr.bgp] /file print
# NAME TYPE SIZE CREATION-TIME
0 route.txt .txt file 73037417 may/15/2009 09:40:40
[agusr@rr.bgp]


routing table bgp (international) jika di jadikan file sekitar 72 MB, ada yang mengklaim dengan router 128MB ram cukup untuk menangani proccess ini. Non router machine and network proccessor ? I don’t think so.

Configurasi di atas menggunakan RoS MT dengan RAM 2GB, Q2Quad 8200 dan butuh waktu sekitar 20 detik untuk mengExport routing table untuk 1 Peering International multi hop n full route advertise. Bagai mana dengan 2 Peering International ? ( 20detik x 2 ) atau 4 Peering ? ( mungkin berasap kali ya )

Max connection squid

Berdasarkan case Sat Mar 21 03:25:33 WIT 2009, posisi client menggunakan download manager dengan 60 thread simultaneous connection, sekitar 4 bilik. Tidak perlu dbahas apa yang terjadi dengan mesin proxy server @_@.

# buka squid.conf
# vim -N /etc/squid/squid.conf

# code
acl localnet 192.168.0.0/24
acl limitconn maxconn 20
http_access deny localnet limitconn

# reconfigure / restart squid.
squid -k reconfigure atau /etc/init.d/squid restart
