ok, sorry ya untuk mas akira, saya terlambat replynya
berhubung email anda terselip diantara ratusan email2 milis2:P
btw lain kali untuk lebih cepat, mohon di subjectnya ditambahkan
TANYA ya.. soalnya saya sort email2 dengan subject tsb kedalam
inbox tersendiri.

ok..
saya asumsi hdd ide kan mas akira ?..
kita buat partisi seperti begini saja..
kalau untuk proxy ini dibutuhkan memory yang cukup besar,
dan sebaiknya ada hdd sendiri untuk system & log dan
hdd tersendiri untuk cache.
Misalkan tidak ada.. kita buat seperti ini..
/boot -> 256 MB --> /dev/hda1
/swap --> 512 MB --> /dev/hda2 (ukurannya antara 2-3 kali RAM)
/cache --> 10000 MB --> /dev/hda3
sisanya buat jadi extended --> /dev/hda4
logical partition.. (/dev/hda5 and seterusnya)
/ ---> 8192 MB --> /dev/hda5
/var --> 4096 MB --> /dev/hda6
/home --> sisanya --> /dev/hda7
format partisi /cache itu dengan reiserfs.
/sbin/mkreiserfs -h r5 /dev/hda3
edit fstab bagian /cache ubah jadi seperti line dibawah ini :
/dev/hda3 /cache reiserfs notail,noatime 1 2
untuk config squid :
edit terlebih dahulu file :
/usr/include/bits/types.h
ganti :
/* Number of descriptors that can fit in an `fd_set'. */
#define __FD_SETSIZE 1024
^^^^
menjadi :
/* Number of descriptors that can fit in an `fd_set'. */
#define __FD_SETSIZE 8192
^^^^
download dlmalloc di
ftp://g.oswego.edu/pub/misc/malloc.c
download squid di http://
http://www.squid-cache.org/Versions/v2/2.4/squid-2.4.STABLE7-src.tar.gz
extract squid :
tar -xvzf squid-2.4.STABLE7-src.tar.gz
copy malloc.c ke squid_extract_dir/lib/dlmalloc.c :
cp malloc.c squid-2.4.STABLE7/lib/dlmalloc.c
enable large fdset.
ulimit -HSn 8192
masuk ke direktori squid :
cd squid-2.4.STABLE7
export CFLAGS environment variable :
export CFLAGS="-O6 -s -DNUMTHREADS=24"
configure squid seperti ini :
./configure --enable-dlmalloc --with-pthreads \
--enable-async-io=24 --enable-poll \
--enable-arp-acl --enable-snmp \
--enable-removal-policies --prefix=/usr \
--exec_prefix=/usr --bindir=/usr/sbin \

coba nyalakan squid anda.. dan testing..
jgn lupa ubah acl squid anda untuk supaya bisa
memperbolehkan access dari ip2 anda.
