Tutorial Cara Install PPTP Server di Linux Debian

• Remote Access, dengan VPN kita dapat mengakses komputer atau jaringan kantor, dari mana saja selama terhubung ke internet
•  Keamanan, dengan koneksi VPN kita bisa berselancar dengan aman ketika menggunakan akses internet publik seperti hotspot atau internet cafe.
•  Menghemat biaya setup jaringan, VPN dapat digunakan sebagai teknologi alternatif untuk menghubungkan jaringan lokal yang luas dengan biaya yang relatif kecil, karena transmisi data teknologi VPN menggunakan media jaringan public yang sudah ada tanpa perlu membangun jaringan pribadi.

• Koneksi internet (jaringan publik) yang tidak bisa kita prediksi. Hal ini dapat kita maklumi karena pada dasarnya kita hanya �nebeng� koneksi pada jaringan pihak lain sehingga otomatis kita tidak mempunyai kontrol terhadap jaringan tersebut.
• Perhatian lebih terhadap keamanan. Lagi-lagi karena faktor penggunaan jaringan publik, maka kita perlu memberikan perhatian yang lebih untuk mencegah terjadinya hal-hal yang tidak diinginkan seperti penyadapan, hacking dan tindakan cyber crime pada jaringan VPN
• Dan banyak lagi, mohon tambahan dan koreksinya

Tutorial Setting Routing Dinamis OSPF di Mikrotik Server VPN

• Setiap router membuat Link State Packet (LSP)
• Kemudian LSP didistribusikan ke semua neighbour menggunakan Link State Advertisement (LSA) type 1 dan menentukan DR dan BDR dalam 1 Area.
• Masing-masing router menghitung jalur terpendek (Shortest Path) ke semua neighbour berdasarkan cost routing.
• Jika ada perbedaan atau perubahan tabel routing, router akan mengirimkan LSP  ke DR dan BDR melalui alamat multicast 224.0.0.6
• LSP akan didistribusikan oleh DR ke router neighbour lain dalam 1 area sehingga semua router neighbour akan melakukan perhitungan ulang jalur terpendek.

• Mengaktifkan OSPF instance

Ubuntu Setting up an NFS Server and Client

What is NFS?

"NFS stands for Network File System, a file system developed by Sun Microsystems, Inc. It is a client/server system that allows users to access files across a network and treat them as if they resided in a local file directory"

"The NFS protocol is designed to be independent of the computer, operating system, network architecture, and transport protocol. This means that systems using the NFS service may be manufactured by different vendors, use different operating systems, and be connected to networks with different architectures. These differences are transparent to the NFS application, and thus, the user. "
[ source ]

Host Installation Steps

To set up an NFS host in Ubuntu, you need to run the following command to install the necessary packages:

sudo apt-get install nfs-kernel-server nfs-common -y

Add lines to your

sudo $EDITOR /etc/exports

Heres another example with comments explaining each part.

# Share the top level files directory
# Allow access from computers accessing from the IPs in the range of 192.168.1.1 -> 192.168.1.255
# The client can access/edit files as if they were a root user on the host
# Grant both read and write access (rw)
/files 192.168.1.1/24(rw,no_root_squash,async)

root_squash or no_root_squash?

The option root_squash prevents root users connected remotely from having root privileges and assigns them the nfsnobody user ID. This effectively "squashes" the power of the remote root user to the lowest local user, preventing unauthorized alteration of files on the NFS host.

The alternative option no_root_squash, allows the root user on the client to access/create files as root on the NFS host which is dangerous, so dont enable this unless you know that you need to. Typically this is needed if one is hosting root filesystems on an NFS server for diskless clients (e.g. AWS EC2).

async or sync?

Async mode (which is the default) means that the system will reply to a clients write request, stating that it has completed, as soon as it has handled the request by passing it off to the filesystem to manage, rather than waiting for it to be written to stable storage (e.g. replying as soon as it has gone into cache rather than disk). This yields much better performance at the expense in a risk of data corruption should the server reboot or lose power whilst still holding data in cache.

If your system needs to work with other proprietary systems that work with NFS (Solaris, HP-UX, RS/6000, etc.), you will need to enable sync mode.

subtree_check or no_subtree_check?

There is a great explanation of this here, but to sum up, the subtree_check causes the host to check that a client request is not going outside the domain of the exported directory. This is only necessary when you are exporting a subdirectory within a filesystem and not the entire filesystem. However, this can cause issues, so the best choice of action is this: always use no_subtree_check (the default), and if you are making a public NFS, then set up the disk partitions so that you are only ever exporting entire filesystems.

Applying Export Changes

Whenever you make changes to the /etc/exports file, for them to take effect you need to run the following command which will let you know if there are any issues, and tell you about any defaults it assumes.

sudo exportfs -a

Restart NFS Service

You can restart the NFS service at any point with the following command:

sudo /etc/init.d/nfs-kernel-server restart

Client Steps

To be able to mount NFS shares as a client, you need to run the following command to install the relevant packages:

sudo apt-get install nfs-common -y

Mount the NFS by adding a line to your /etc/fstab file like below:

$NFS_HOST_IP:$HOST_EXPORT_DIR_PATH $LOCAL_DIR nfs auto 0 0

The last 0 indicates that we should never perform filesystem checks for this on boot (fsck).

Now run the following command to mount everything in your fstab.

sudo mount -a

If you just want to mount once, and not automatically on startup, then instead of adding to your fstab and calling mount -a, simply run this instead:

sudo mount $NFS_HOST_IP:$HOST_EXPORT_DIR_PATH $LOCAL_DIR

Tutorial Setting Mikrotik dan Proxy Server Squid di Virtual Box

• Virtual Box 
• Mikrotik routerOS.iso
• Ubuntu Server.iso

Planing Network Instalasi
Setting network sesuaikan adapternya :

Virtual Mikrotik :
Adapter1 : Bridge ( interface mengarah ke modem/internet )
Adapter2 : Internal network
Adapter3 : host-only adapter

Virtual Squid :
Adapter1 : Internal network

Ilustrasinya seperti gambar dibawah :

Keterangan :

• PC master adalah PC yang di install Virtual box.
• Pada eth0 di PC master, saya beri tanda X karna eth0(PC) hanya akan menjadi jembatan eth0 (mikrotik) dengan demikan agar PC master dapat mengakses internet melewati eth2 (mikrotik) sebagai Client dari mikrotik walaupun pada eth0 (PC) adalah client dari internet/setara dengan mikrotik

• Hilangkan centang pada TCP/IPv4 pada adapter yang digunakan untuk mengakses inter pada PC master untuk mendapatkan tanda X di eth0(PC) tadi.

Dalam praktek ini saya menggunakan jaringan wireless rumahan wifi (speedy) namun sama saja setinggannya untuk kabel LAN. 
Setting IP masing-masing Machine nya seperti dibawah :

PC master

adapter 1 = <kosong>

adapter 2 = 192.168.3.2

virtual mikrotik

adapter 1 = 192.168.1.1

adapter 2 = 192.168.2.1

adapter 3 = 192.168.3.1

virtual squid

adapter 1 = 192.168.2.2

untuk adapter 2 pada PC, adalah adapter virtual yang telah di buat secara default oleh virtualbox agar PC master dapat terkoneksi dengan mesin virtual, lihat gambar untuk lebih jelasnya :

Topologi dengan IP

Dapat disimpulkan bahwa :

# Jaringan 192.168.1.0 adalah jaringan internet

# Jaringan 192.168.2.0 adalah jaringan proxy

# Jaringan 192.168.3.0 adalah jaringan client

Untuk settingan mikrotik saya seperti ini :

Setting client agar dapat redirect ke proxy : tambahkan NAT rules

## Firewall => Nat

action : dst-domain

src address : !192.168.2.2

protocol : tcp

dst port : 80

action  : dst-nat

to adresses : 192.168.2.2

to ports : 3128

Copy - Paste di New Terminal

Untuk Konfigurasi Squid, Sesuaikan dengan gambar dibawah ini :





Silahkan dikembangkan lagi materi diatas, karna konfigurasi squid nya masih default, semoga bermanfaat.
