      Ok. Aku akan mencobanya….
      Trima kasih ya atas pencerahannya....
      Salam....

      btw... hdd aku cuman 1, bisa ngak aku naikkan cache dirnya menjadi 20GB ato lebih? apa ad pengaruh di kinerjanya?

      bisa, dengan RAM 1 Gb perkirakan saja kebutuhannya, naikin saja cache_dir 40 Gb, dan sebaiknya cache_dir digunakan tdk  lebih dari 50% partisi fisik contoh partisi fisik 80Gb maka utk cache_dir maximum 40Gb, jika menggunakan cache_dir  diatas 50%  dari partisi fisik, maka paralel thread spindel hardisk akan berubah dari optimasi time ke optimasi space (akan keluar pesan messages dr syslog). rekomendasi yang lainnya katanya 80%, namun dalam praktek jika request rata2 diatas 100 hit/s dan kondisi cache_dir sudah penuh, kerja hardisk jadi loyo untuk read/write/delete, saran dari addrian chad (developer squid) gunakan cache_dir tidak lebih dari 50%  partisi fisik.

          coba di paste ke sini hasil

          $ squidclient -p 80 cache_object://localhost/ mgr:config >/tmp/config

                  @ipoelnet:

                  3 GB OM,.. Proc DualCore 2.2

                  partisi fisik cache1 = 70 GB
                  partisi fisik cache12 = 80 GB
                  tambahkan  option rw,noatime di fstab

                  cache_dir aufs /cache1 32768 64 256 min-size=65535
                  cache_dir aufs /cache2 40960 64 256 max-size=65535
                  store_dir_select_algorithm round-robin

                  atau bisa menggunakan coss utk file2 kecil, cuman rada ribet sedikit membuatnya :D

                    Setelah Q tambah

                    rw,noatime – > partisinya yg di tambah param itu kok g' bisa muncul OM?
                    Maksudnya untuk option ini

                    32768 64 256 min-size/max-size=65535 –> huruf tebal apa OM

                    kan biasanya :

                    32768 16 256

                    Mau donk kalau bisa yang pakai Coss….biar tambah wussssssss he he

                      edit /etc/fstab

                      contoh :

                      
proxy# cat /etc/fstab
# Device                Mountpoint      FStype  Options         Dump    Pass#
/dev/ad0s1g             /cache            ufs     rw,noatime      2       2

                      supaya berefek bisa di reboot, atau di umount /cache baru di mount /cache

                      cara ngeceknya, ketik
                      mount
                      hasilnya salah satunya ada :
                      /dev/ad0s1g on /cache (ufs, local, noatime, soft-updates)

                      max-size=ukuran maksimum yang di izinkan  di cache (dalam byte)
                      min-size=ukuran minum yang di izinkan  di cache (dalam byte)

                      cache_dir aufs Directory-Name Mbytes L1 L2 [options]

                      L2 di rekomendaiskan 256
                      LI di sesuaikan dengan besaran partisi

                      dari om Henrik
                      _simplified formula:

                      L2 = 256
                      L1 = cache_dir size / 500, rounded upwards on small numbers..

                      If L2 is changed or you have a singnificantly different object size
                      distribution then use the equation above. This simplified formula is
                      only valid for L2 = 256 and average object size of about 13KB.

                      Regards
                      Henrik_

                                    inti masalahnya di dns, bisa karena bottleneck jaringan / karena dns server tidak cepat merespon query dns client
                                    solusi :
                                    1. coba sih squid -v

                                    apakah ada option –disable-internal-dns, kalau ada upgrade squid nya, gunakan internal dns saja lebih ok

                                    2. coba di nslookup abc.com dari client, apakah server bisa cepat merespon,
                                    jika menggunakan dnsmasq, tambahkan cache-size=10000  (10Mb) atau naikkan pelan2, sesuikan dengan ram fisik, jika masih tetap saja bussy berarti segera buat dns-cache selain dnsmasq, dnsmasq hanya utuk net kecil, solusinya buat dedicated dns-server (bukan di box pfsense), recomend gunakan bind atau djbdns

                                    jika menggunakan bind, tambahkan option datasize 12M; max-cache-size 10M; naikkan pelan2, dengan client +/- 2000 nilai 256M sudah sangat responsif

                                    3. tambahkan di squid.inc half_closed_clients off

                                    block ultra yang tunneling ke port 443 banyak cara, bisa lewat firewall/squid

                                    1. lewat squid

                                    tambahkan  di squid.inc

                                    acl numeric_IPs url_regex ^[0-9]+.[0-9]+.[0-9]+.[0-9]+
                                    http_access deny CONNECT numeric_IP all

                                    kelemahannya gak bisa buka web yang menggunakan ip, hanya bisa domain,
                                    contohnya skype jk melakukan call menggunakan numerik ip acak, bukan domain, jadi gak bisa connect hehehe  ;D

                                    2. lewat firewall, block ip ultrasurf, lihat di attachment, banyak sekali hehehe

                                    untuk virus, kalau client menjalankan aplikasi yang bervirus dan mengandung trojan / hijack browser, solusi satu2nya basmi virusnya di client, firewall secanggih apapun gak bisa ngapa2in, trojan itu destination  ip dan portnya acak, ini yang susah

                                      Oh ya om untuk Skypi Q nyontoh

                                      http://www1.cs.columbia.edu/~salman/skype/BlockingSkype_corp.pdf

                                      acl numeric_IPs urlpath_regex ^[0-9]+.[0-9]+.[0-9]+.[0-9]+

                                      This post will explain a quick and dirt method to block Skype for some user, but avoid to block access to https urls not defined as FQDN.

                                      This post assume that your client have non direct Internet access and must pass trough your Squid Proxy Server to have an external connection.
                                      This Post assume your local network is 192.168.1.0/24
                                      This post assume you want to give SKYPE access to IPs from 192.168.1.100 to 192.168.1.200 and you want to give internet access to all your network.

                                      Obviously you MUST change the IPs based on your REAL network configuration.

                                      In the following configuration, I’m going to create some ACL to define my networks, the skype connection method, skype connections destinations and create a sort of WhiteList that could fill in with some exceptions to avoid https connection problems.

                                      The WhiteList file is /etc/squid/https_url_allowed and you can fill in with a single ip address for line, example :

                                      proxy:~ # cat /etc/squid/https_url_allowed

                                      aaa.bbb.ccc.ddd
                                      eee.fff.ggg.hhh

                                      uuu.vvv.www.xxx

                                      proxy:~ #

                                      All the following lines is in the main SquidProxy Configuration file, usually /etc/squid/squid.conf

                                      # Declare an ACL to catch ALL
                                          acl all src 0.0.0.0/0.0.0.0
                                          # Define an ACL to define my local network

                                      # Allow Internet access to all “mynetworks”

                                      # And finally deny all other access from this proxy
                                          http_access deny all

                                      At this point you can restart squid an check if all works with :

                                      /etc/init.d/squid restart

                                      Hope this help

                                        All dnsserver processes are busy

                                        inti masalahnya di dns, bisa karena bottleneck jaringan / karena dns server tidak cepat merespon query dns client
                                        solusi :
                                        1. coba sih squid -v

                                        apakah ada option –disable-internal-dns, kalau ada upgrade squid nya, gunakan internal dns saja lebih ok

                                        2. coba di nslookup abc.com dari client, apakah server bisa cepat merespon,
                                        jika menggunakan dnsmasq, tambahkan cache-size=10000   (10Mb) atau naikkan pelan2, sesuikan dengan ram fisik, jika masih tetap saja bussy berarti segera buat dns-cache selain dnsmasq, dnsmasq hanya utuk net kecil, solusinya buat dedicated dns-server (bukan di box pfsense), recomend gunakan bind atau djbdns

                                        jika menggunakan bind, tambahkan option datasize 12M; max-cache-size 10M; naikkan pelan2, dengan client +/- 2000 nilai 256M sudah sangat responsif

                                        3. tambahkan di squid.inc half_closed_clients off

                                        block ultra yang tunneling ke port 443 banyak cara, bisa lewat firewall/squid

                                        **1. lewat squid

                                        tambahkan  di squid.inc

                                        acl numeric_IPs url_regex ^[0-9]+.[0-9]+.[0-9]+.[0-9]+
                                        http_access deny CONNECT numeric_IP all

                                        kelemahannya gak bisa buka web yang menggunakan ip, hanya bisa domain,
                                        contohnya skype jk melakukan call menggunakan numerik ip acak, bukan domain, jadi gak bisa connect hehehe  ;D**

                                        2. lewat firewall, block ip ultrasurf, lihat di attachment, banyak sekali hehehe

                                        untuk virus, kalau client menjalankan aplikasi yang bervirus dan mengandung trojan / hijack browser, solusi satu2nya basmi virusnya di client, firewall secanggih apapun gak bisa ngapa2in, trojan itu destination  ip dan portnya acak, ini yang susah

                                        klo lewat transparent squid bgmn yaa?? klo squid dijadikan transparent hanya port 80 yang di direct ke squid…. mohon pencerahannya....

                                          Untuk metode yang HTTPS atau IP Acak, ya katah Om grage itu solusinya, blm ada port 443 dijadikan transparent, kalau mau obok2 privasi misal YM, ICQ, dan email ya di squid di tambah method CONNECT seperti om grage bilang.
