Monitoring Squid with MRTG

If you want to know utilization or performance your Squid Proxy, you can use MRTG to monitoring Squid Proxy. This can do, because Squid Proxy support SNMP and you must configure squid with SNMP support.

What is Dark Fiber

Dark fiber is a term used to describe fiber optic cable that is not being used at the time. The amount of dark fiber, particularly in the United States, is very high. Dark fiber is contrasted with active fiber optic cable, often referred to as lit cable.

In the past, dark fiber was virtually never sold. Telecommunications companies considered it their core asset, and selling it would be akin to selling off their business. Due to an incredible glut in the market, however, selling dark fiber has become extremely viable and is now a practice of many major telecommunications companies.

Testing Network Limit with Iperf

What Is Iperf?

Iperf is a tool to measure maximum TCP bandwidth, allowing the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss.

Features

TCP

Measure bandwidth
Report MSS/MTU size and observed read sizes.
Support for TCP window size via socket buffers.
Multi-threaded if pthreads or Win32 threads are available. Client and server can have multiple simultaneous connections.

Setting Up Squid on FreeBSD

Squid is web caching and conserving badwidth application. With Squid, we will reduce the traffic 30% or more from normal usage (without squid) and enhance respone time. In here, i will use squid 2.7.STABLE3.

Installing Squid.
You can download Squid from here. After you download the source of squid, then :

# tar zxvf squid-2.7.STABLE3.tar.gz
# cd  squid-2.7.STABLE3
# ./configure '--sysconfdir=/etc/squid' '--enable-storeio=diskd,ufs,aufs' '--enable-delay-pools' \
'--enable-pf-transparent' '--enable-ipf-transparent' '--disable-ident-lookups' \
'--enable-removal-policies'
# make
# make install

Try With Something New

I try something new last 3 days ago. I had move from Drupal to Joomla. I just want to try, how about with joomla for my blog, so I am sorry if there so many links change.

I hope with joomla I can find something new, something different then before.

Thanks to Fandi and Heru for help so I can use joomla for my blog.

Again, we will learn and share together...

Step By Step FreeBSD as Internet Server

Installing FreeBSD

1. 1. Select Region.
   2. Select Standart Installation.
   3. Use all drive for FreeBSD.
   4. Create Disklabel, on my installation use 80GB of harddisk, and here my disk label
      • / 512MB
      • swap 1GB
      • /tmp 1GB
      • /usr 4GB
      • /var 2GB
      • /home 1GB
      • /cache (all the rest off harddisk space).

Load Balancing on MikroTik

Quick Start for Impatient Configuration export from the gateway router:

/ ip address add address=192.168.0.1/24 network=192.168.0.0 broadcast=192.168.0.255 \
interface=Local comment="" disabled=no

add address=10.111.0.2/24 network=10.111.0.0 broadcast=10.111.0.255 \
interface=wlan2 comment="" disabled=no

add address=10.112.0.2/24 network=10.112.0.0 broadcast=10.112.0.255 \
interface=wlan1 comment="" disabled=no

The Easy Way to setting Mikrotik + Squid and Simple Queue

In a Case, there is my client wishing topology in its(the network using machine Mikrotik which will be joined forces with Squid, where this Squid stays in machine FreeBSD. He wishs, arrangement of shaping easily, by using Simple Queue.

If topology like this : INET ------- Mikrotik --------- SQUID -------- Client

Bandwidth Management is handle by SQUID. We wanted is like this :

INET | Mikrotik ---- SQUID | Client

So, shaping to client is handle by Mikrotik.

User Datagram Protocol (UDP)

User Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. Using UDP, programs on networked computers can send short messages sometimes known as datagrams (using Datagram Sockets) to one another. UDP is sometimes called the Universal Datagram Protocol. It was designed by David P. Reed in 1980.
