Setting pdnsd di Ubuntu Server

Written by Bima Firewall 0 comments Posted in: Ubuntu

Pdnsd adalah DNS cache proxy...Proses meminta terjemahan nama domain ke IP address ini dari komputer kita ke DNS server ISP tidak lama, rata-rata memakan waktu 500 milidetik, alias setengah detik. namun bayangkan jika DNS server ISP itu bisa kita pindahkan ke dalam jaringan lokal di rumah, maka proses penerjemahan nama domain tadi bisa disingkat sampai cuma tinggal 1 milidetik. jika seharian kita melakukan ratusan permintaan penerjemahan nama domain, banyak waktu yang bisa dihemat jika DNS server-nya ada di jaringan lokal.

untuk mengetahui berapa lama proses yang dibutuhkan untuk melakukan penerjemahan nama domain ini, di linux maupun mac bisa digunakan perintah dig.

langkah - langkah :

# sudo apt-get update

# sudo apt-get install pdnsd

edit usr/share/pdnsd/pdnsd-resolvconf.conf

/* Debian specific configuration to work with resolvconf */

global {
    perm_cache = 1024;
    cache_dir = "/var/cache/pdnsd";
    run_as = "pdnsd";
    server_ip = any; // Use eth0 here if you want to allow other
                            // machines on your network to query pdnsd.
    status_ctl = on;
    paranoid = on;
    min_ttl = 15m;          // Retain cached entries at least 15 minutes.
    max_ttl = 1w;           // One week.
    timeout = 10;           // Global timeout option (10 seconds).
}

/* server {
    label = "resolvconf";
    proxy_only = on;
} */

    label=DNSpeedy;

/* vim:set ft=c: */

edit lagi di /etc/default/pdnsd :

# do we start pdnsd ?
START_DAEMON=yes
# auto-mode, overrides /etc/pdsnd.conf if set [see /usr/share/pdnsd/]
AUTO_MODE=

}

/* vim:set ft=c: */

edit /etc/resolv.conf

name-server nameserver 127.0.0.1

edit /etc/dhcp/dhclient.conf :

#prepend domain-name-servers 127.0.0.1; hilangkan tanda # 

tambahkan pada rc.local :

/etc/init.d/pdnsd restart

langsung di test :

sudo /etc/init.d/pdnsd restart

semua langkah pengeditan harus di simpan setelah di edit/ditambahkan...

192.168.2.2 IP server... di sesuaikan IP server anda...

Selamat Mencoba ^_^

Membuat Jalur Ping dan DNS

Written by Bima Firewall 0 comments Posted in: Mikrotik

Pada jaringan yang dilimit, ketika batas bandwidth suatu client telah maksimal digunakan, maka ping akan membesar nilai reply-nya, hal ini dikarenakan pengantrian koneksi dari client itu sendiri. Sehingga seolah-olah koneksi yang kita pakai memiliki kualitas jelek karena ping yang besar.

Bagaimana caranya agar ping tetap stabil walau koneksi telah full digunakan oleh client itu sendiri, begitu juga halnya dengan DNS (port 53) agar lebih cepat dalam pengalokasian address, pada tulisan ini kita akan membuat jalur sendiri icmp dan dns, dan diharapkan tanpa adanya gangguan dari koneksi, sehingga koneksi penyampaian ping dan dns bisa lebih cepat.

/ ip firewall mangle

add chain=prerouting protocol=icmp src-address=192.168.10.0/24 action=mark-connection new-connection-mark=icmp-c comment="--> ping" disabled=no

add chain=prerouting connection-mark=icmp-c action=mark-packet new-packet-mark=icmp-p comment="" disabled=no

add chain=prerouting packet-mark=dns-p action=change-tos new-tos=min-delay comment="" disabled=no

Jika pada mangle terdapat mark packet nya koneksi (IIX / INT) letakkan di bagian bawah mangle tersebut, dan jangan diletakkan di bagian atas. Selanjutnya pada queue type:

/ queue type

add name="64" kind=pfifo pfifo-limit=64

Pada queue tree:

/ queue tree

add name="64" parent=global-in packet-mark="" limit-at=0 queue=64 priority=5 max-limit=32000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no

add name="ping" parent=64 packet-mark=icmp-p limit-at=8000 queue=64 priority=1 max-limit=16000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no

Internal Proxy dari Cache Internal Mikrotik

Written by Bima Firewall 0 comments Posted in: Mikrotik

Menggunakan Internal Proxy nya mikrotik versi crack(2.9) ternyata masih bisa. dari pada pakai komputer lagi mending pakai Internal Proxy nya saja. cuman hasilnya memang belum seoptimal kalo pakai external proxy(terutama di bagain bandwith manjemennya) tetapi masih memuaskan. (sudah ditest cuman kadang terasa kurang memuaskan, tetapi bisa membantu meningkatkan perfoma)

Seting IP untuk Internal Proxy pada mikrotik

1. IP Modem:
- 192.168.10.1
2. IP Mikrotik:
- 192.168.1.1 = local
- 192.168.10.2 = public/ke modem speedy

3. IP Client: 192.168.1.0/24

Seting Rule Internal Proxy di Winbox :

Optimalkan Ping Internet

Written by Bima Firewall 0 comments Posted in: Mikrotik

Ada yang bilang proxy bukan untuk hemat bendwith tetapi makan icmp (ping), mungkin ini solusinya :

1. Pertama, aktifkan dulu ip firewall di bridgenya, commandnya seperti ini …
lihat bridge setting, apakah ip firewall sdh aktif apa belum …

[wiwid@funny-mikrotik] /interface bridge settings> pr
use-ip-firewall: no
use-ip-firewall-for-vlan: no
use-ip-firewall-for-pppoe: no
ternyata use-ip-firewall masih belum aktif.

ktifkan use-ip-firewallnya ,
[wiwid@funny-mikrotik] /interface bridge settings> set use-ip-firewall=yes
oK sekarang kita lihat hasil printnya …

[wiwid@funny-mikrotik] /interface bridge settings> pr
use-ip-firewall: yes
use-ip-firewall-for-vlan: no
use-ip-firewall-for-pppoe: no

Bisa dilihat, use-ip-firewall sdh diaktifkan.

2. Buat Mangle :

[wiwid@funny-mikrotik] /ip firewall mangle>add chain=prerouting action=mark-connection new-connection-mark=icmp-conn passthrough=yes protocol=icmp
[wiwid@SGH-JCO Salam] /ip firewall mangle>add chain=prerouting action=mark-packet new-packet-mark=tcp-conn passthrough=no protocol=icmp connection-mark=icmp-conn

3. Buat Queue Tree

[wiwid@funny-mikrotik] /queue tree> add name=”ICMP” parent=global-total packet-mark=tcp-conn limit-at=48k queue=default priority=8 max-limit=96k burst-limit=96k burst-threshold=64k burst-time=5s

Test : ping 192.168.1.2 -l 1472 -t

Pengaturan Proxy Eksternal Dengan Mikrotik

Written by Bima Firewall 0 comments Posted in: Mikrotik

Mikrotik routerboard memiliki built-in proxy didalamnya, namun memiliki kendala yakni keterbatasan kapasitas penyimpanan. Oleh karena itu, kebanyakan administrator jaringan yang menggunakan mikrotik akan menggunakan proxy eksternal untuk mengatasi kendala ini.

Program atau daemon yang paling banyak digunakan untuk proxy eksternal adalah squid atau turunannya (lusca). Ada beberapa keuntungan dalam penggunaan squid proxy eksternal antara lain :

Mudah untuk di sesuaikan konfigurasinya sesuai dengan kebutuhan.
Penggunaan access control lists (ACL) yang dapat digunakan untuk keperluan tertentu.
Squid (khususnya versi 2.7) dapat “dipersenjatai” dengan url redirector. Pada suatu kondisi, redirector dapat digunakan untuk menangani akses konten dinamik (seperti video Youtube).
Kapasitas penyimpanan yang lebih besar karena pada umumnya komputer menggunakan harddisk sebagai media penyimpanan.

Dalam posting ini, saya akan sedikit menjabarkan integrasi proxy eksternal dengan mikrotik menggunakan pengaturan NAT atau mangle dengan diagram jaringan seperti gambar berikut ini :

Keterangan :

IP address mikrotik menuju proxy : 192.168.90.1
IP address proxy menuju mikrotik : 192.168.90.2
IP address klien-klien : 192.168.1.0/24

Skenario pertama : menggunakan NAT.

Kita dapat menggunakan NAT untuk “membelokkan” akses browsing klien (port 80/HTTP) menuju IP dan port proxy eksternal. Monggo di copas script berikut ini :

/ip firewall address-list
add address=192.168.90.0/24 list=ip-proxy
/ip firewall nat
add action=dst-nat chain=dstnat comment="transparent proxy" dst-port=80 protocol=tcp src-address-list=!ip-proxy to-addresses=192.168.90.2 to-ports=3128

Keterangan :

Terlebih dahulu kita mendeskripsikan kelas IP address yang digunakan untuk komunikasi antara mikrotik – proxy.

/ip firewall address-list
add address=192.168.90.0/24 list=ip-proxy

Kemudian, akses browsing klien (HTTP port 80) kita belokkan menuju proxy eksternal port 3128

/ip firewall nat
add action=dst-nat chain=dstnat comment=”transparent proxy” dst-port=80 protocol=tcp src-address-list=!ip-proxy to-addresses=192.168.90.2 to-ports=3128

Skenario kedua : menggunakan mangle.

Saya secara pribadi menyukai penggunaan skenario kedua ini. Berikut script nya :

/ip route
add check-gateway=ping distance=1 gateway=192.168.90.2 routing-mark=to-ext-proxy
/ip firewall mangle
add action=mark-routing chain=prerouting comment="mark routing to proxy" dst-port=80 new-routing-mark=to-ext-proxy protocol=tcp src-address=192.168.1.0/24

Keterangan :

Sebelumnya, tambahkan route menuju proxy eksternal untuk routing yang akan kita tandai di mangle.

/ip route
add check-gateway=ping distance=1 gateway=192.168.90.2 routing-mark=to-ext-proxy

Setelah itu, akses browsing klien kita tandai dengan routing mark pada mangle, sehingga semua akses browsing akan “bermuara” langsung ke proxy eksternal sebagaimana telah kita tentukan sebelumnya pada route.

/ip firewall mangle
add action=mark-routing chain=prerouting comment=”mark routing to proxy” dst-port=80 new-routing-mark=to-ext-proxy protocol=tcp src-address=192.168.1.0/24

Catatan :

Jangan lupa menambahkan pengaturan pada proxy eksternal agar akses klien dapat berjalan dengan baik antara lain menentukan default gateway proxy dan mengizinkan akses port 3128 pada iptables. Simpan baris-baris berikut ini kedalam file /etc/rc.local :

route add default gateway 192.168.90.1
iptables -A PREROUTING -t nat -j REDIRECT -p tcp -s 192.168.1.0/24 -d 0/0 --dport 80 --to-ports 3128
iptables -A INPUT -p tcp -s 0.0.0.0/0 -d 192.168.90.2 -m state --state NEW,ESTABLISHED -j ACCEPT
iptables -A OUTPUT -p tcp -s 192.168.90.2 --sport 3128 -d 0.0.0.0/0 -m state --state ESTABLISHED -j ACCEPT

Ubuntu feat BTRFS

Written by Bima Firewall 0 comments Posted in: Ubuntu

BTRFS ini adalah format file 
system pada ubuntu yang katanya sih kenceng banget buat ngecache squid 
proxy feat lusca, dari makyuz jadi mak nyuooozzzz...... hehe,,,,, 
postingan kali ini hanya sebagai catatan aja daripada lupa,

dari konsole ketikkan :

aptitude install zlib1g-dev zlibc btrfs-tools bzip2

cek apakah module sudah terload di system :

lsmod |grep -i btrfs

jika sudah tinggal format/convert saja,
utk format partisi ke btrfs
contoh :

mkfs.btrfs /dev/sdxx

untuk convert :
Must run fsck first

fsck.ext4 -f /dev/xxx

Convert from Ext3/4-> Btrfs

#btrfs-convert /dev/xxx

kalau sudah sukses test dengan mount

#mount -t btrfs /dev.sdxx /cachexxx

cek dengan perintah mount :

#mount
/dev/sda3 on /cache type btrfs (rw)

jika ingin permanin saat boot, edit /etc/fstab
misal :

/dev/sda3 /cache btrfs noatime,compress,noacl,barrier=0 0 1

selanjutanya step2nya seperi biasanya

#chown proxy:proxy /cachexx
#chmod 777 /cachexxx
#squid -z
#/etc/init.d/squid start

tambahan kalau pas perintah modprobe error seperti ini

modprobe libcrc32c zlib_inflate zlib_deflate btrfs
FATAL: Error inserting libcrc32c (/lib/modules/2.6.32-21-generic-pae/kernel/lib/libcrc32c.ko): Unknown symbol in module, or unknown parameter (see dmesg)

harus install kernel-headernya

uname -a

cek dulu dengan uname -a
aptitude install linux-headers-”uname-a”
misal disitu pake versi kernel 2.6.32-21-generic-pae

aptitude install linux-headers-2.6.32-21-generic-pae

trs di reboot
baru install :

aptitude install btrfs-tools
modprobe btrfs
lsmod |grep -i btrfs

agar dikenali secara permanen maka lakukan

/etc/modules
modprobe btrfs

Optimalkan Ping Modem ADSL

Written by Bima Firewall 0 comments Posted in: Tutor

Ping adalah software yang berjalan di atas protokol ICMP (Internet Control Message Protocol) untuk mencek hubungan antara dua komputer di internet. Ping dapat juga berarti program dasar yang mengijinkan satu pengguna untuk mem-verifikasi bahwa alamat protokol internet tertentu ada dan dapat menerima permintaan-permintaan. Ping digunakan untuk memastikan bahwa satu komputer yang sedang dituju sedang aktif dan memberikan respon balik.

Langkah-Langkahnya sebagai berikut :

1. Reset Modem Anda, Kenapa musti di reset agar settingan modem benar-benar settingan default dari perusahaan modem tanpa ada settingan sebelumnya.

2. Setting Ulang Akun Modem sesuai provider masing-masing

2. Disable UPnP, atau non Ceklist pada point UPnP

3. ADSL Setting menggunakan G.DMT

4. Disable bitswap

5. Disable SRA

6. Reboot/ Restart

Sekarang coba ping ke website yang anda inginkan, sambil browsing, download, maka ping tetap stabil tanpa terputus...
