                  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

                    Oh ya om untuk Skypi Q nyontoh

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

                    Your acl definitions

                    acl numeric_IPs urlpath_regex ^[0-9]+.[0-9]+.[0-9]+.[0-9]+
                    acl connect method CONNECT

                    Apply your acls

                    http_access deny connect numeric_IPs all
                    dan
                    http://www.riccardoriva.com/archives/275
                    isi :
                    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
                    iii.jjj.kkk.lll
                    mmm.nnn.ooo.ppp

                    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
                        acl mynetworks src 192.168.1.0/24
                        # Define an ACL to have some IPs that can connect to SKYPE
                        acl skype_users src 192.168.1.100-192.168.1.200
                        # Define a CONNECT acl for the CONNECT method
                        acl CONNECT method CONNECT

                    # Define an ACL for the URLs composed only of numbers, not FQDN
                        acl skype_url url_regex ^[0-9]+.[0-9]+.[0-9]+.[0-9]+

                    # Define an ACL for use URLs composed only of numbers, not FQDN
                        acl https_url_allowed url_regex -i “/etc/squid/https_url_allowed”

                    # Allow SKYPE access for the group “skype_users”
                        http_access allow CONNECT skype_url skype_users

                    # Allow https access for IP Addresses defined in “/etc/squid/https_url_allowed”
                        http_access allow CONNECT https_url_allowed

                    # Deny Access to SKYPE and all other
                        http_access deny CONNECT skype_url

                    # Allow Internet access to all “mynetworks”
                        http_access allow 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

                    Bye

                      @grage95:

                      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.
