Speed Up Your Broadband Connection - Ubuntu




Part 1:
After you've installed Ubuntu, you may want to tweak your system further, such as improving how Ubuntu connects to the Internet, and therefore speed up your web surfing.
To accomplish this, we're going to configure IPv6 and the TCP Window Size. Please remember to back up any critical files or data you may need as well as keep records of the settings you change. Doing so will help you recover in the event of a disaster. Keep in mind that you perform these configuration “tweaks” at your own risk.
These configuration tweaks are completed by entering commands into your “Terminal”. We will use Gedit although you can use Vi, nano, etc.
As a side note, if you do not want to enter “sudo” for each command, just begining your terminal session with this command:

sudo su

IPV6 is an Internet protocol. Currently most applications use IPV4 and this can cause conflicts which slow down your system.
Complete the following to disable it.

sudo gedit /etc/modprobe.d/aliases 

and type this in:

alias net-pf-10 off

and put a # before

alias net-pf-10 ipv6


Then save the file.



Speed up Broadband Internet by editing the appropriate configuration file and adding the following information. - Or, you can use a tool called PowerTweak from here: sourceforge.net/projects/powertweak

sudo gedit /etc/sysctl.conf

The first four line deal with window size and you need to enter numbers that are best for you (because these ones may be too high). Here is what I mean by this:
Computers communicate by sending packets of data back and forth. When they connect with each other to send these packets they use the TCP (Transmission Control Protocol).

Your computer could begin the connection with a small package size, then the other computer might respond with a larger one. In turn your computer will reduce (scale down) the size of the package (to a bit more that your original package size). The other computer again responds with a larger packet size. This cycle continues until your computer or the responding computer meets their maximum package size.

If you choose a windows packet size that is too big, you will notice slower broadband performance (524288 works for me). If you notice a slow down, then reduce your window size.
The largest size you can use is 65536, however these are the three settings that seem to work best:

524288
262144
131072
Which are all multiples of 1024 (or 1K).
Now add the following to the end of the file:

net.core.rmem_default = 524288
net.core.rmem_max = 524288
net.core.wmem_default = 524288
net.core.wmem_max = 524288
net.ipv4.tcp_wmem = 4096 87380 524288
net.ipv4.tcp_rmem = 4096 87380 524288
net.ipv4.tcp_mem = 524288 524288 524288
net.ipv4.tcp_rfc1337 = 1
net.ipv4.ip_no_pmtu_disc = 0
net.ipv4.tcp_sack = 1
net.ipv4.tcp_fack = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_ecn = 0
net.ipv4.route.flush = 1


After adding these line you do not need to reboot, instead just reset the file by issuing this command:

sudo sysctl -p

After completing this, you should notice improved web surfing speed. If not, remember to go back and adjust your TCP window size and try again.

The Best Firewalls

Which windows firewall should I use? To make up your mind and have a decision on which windows firewall you should use try going to this website link it will give the best answer whether your existing firewall is working good or not. Here's a short list free windows firewall that you can use and try.....

Free Software Firewalls

PC Tools Firewall Plus

This is a free personal firewall for Windows that provides inbound and outbound filtering. The firewall allows you to create application rules (only to allow or disallow an application) and rules for the packet filter (where you can configure the ports allowed, etc). There are no limitations on the free version. (They survive by selling an all-in-one Internet Suite that not only provides a firewall but also an antivirus, an antispyware and spam protection.)

Outpost Firewall Free

This free version has a subset of the features of the commercial Agnitum Outpost Firewall Pro. It's meant only for personal use. The program has a bidirectional firewall, application behaviour ("behavior" in US English) monitoring, configurable firewall rules, and self-protection (ie, to protect itself from being terminated by malware). Although it lacks the attack detection, log viewer, IP blocklists, antispyware protection (etc) of the full version, it's still seems like a firewall with lots of useful features. This is a Windows firewall.

ZoneAlarm

ZoneAlarm is an easy to use and free personal firewall that is used by many people on the Internet. The free version allows you to decide which applications you can allow to access the Internet, but does not allow you to block specific IP addresses. (Look carefully before you click - the "basic PC protection" link is the one that is free.) This is a Windows firewall. If you want comprehensive protection for your computer, you might want to consider their commercial offering, ZoneAlarm Security Suitewhich includes a firewall as well as antivirus, antispyware, antitrojan , identity theft protection, phishing and spam blocker, etc.

Comodo Internet Security

Comodo Internet Security is a Windows firewall and antivirus suite that filters both inbound as well as outbound traffic. Among its features are the ability to detect application hijacking attempts via its application and component behaviour monitor, self protection against termination attempts by malware, protection of your PC during startup, etc. The free edition has a subset of features of the commercial Comodo Internet Security Pro (which includes Wi-Fi protection, remote live expert help, etc).

SoftPerfect Personal Firewall

SoftPerfect Personal Firewall is a rule-based Windows network firewall that filters IP and non-IP traffic, supports configurations for multiple network adaptors, has a learning mode and comes with a set of predefined rules.

GhostWall

GhostWall is a packet filtering firewall with low resource usage and latency. It works on both 32 bit and 64 bit Windows.

Guarddog

Guarddog is a firewall configuration utility for Linux iptables. It also lets you maintain and modify the firewall in place. It uses a "what is not explicitly allowed, is denied" philosophy. The software is released under the GNU GPL.

WIPFW

WIPFW is a packet filtering and accounting system for Windows. It is based on FreeBSD's IPFW.

Jetico Personal Firewall v1.x

Jetico Personal Firewall v1.x is a Windows 98/ME/NT/2000/XP firewall that has network packet filters, network events filters (that allows you to block application level events) and process activity filters (that hopefully blocks application hijacking attempts where a trojan uses your browser to send information to the internet). The Jetico Personal Firewall v1.x project is "frozen" and is no longer developed.

Firestarter - Free Linux Firewall Tool

Firestarter is an easy-to-use free firewall tool for Linux that has a wizard that allows you to customize your firewall, a real-time firewall monitor that allows you to view intrusion attempts, a graphical interface that works under GNOME and KDE, and support for Linux kernels 2.4 and 2.6. For those who aren't brave enough to muck around with netfilter / iptables, Firestarter is one way to set up your system so that it is protected from intrusions.

Online Armor Free Edition

Online Armor Free is a Windows firewall with a built-in host instrusion prevention (HIPS) system. It also has a form of keylogger detection and includes protection against script/worm attacks. In addition, it features self-protection against tampering and termination attempts by malware. The current version of the firewall, at the time I write this, appears to have performed well in independent leak tests. (For the free version, click the "Download Now" button at the bottom of the page.)

Sunbelt Personal Firewall (formerly Kerio Personal Firewall)

Sunbelt Personal Firewall is free for home use. It controls traffic from your computer to the Internet (thus useful for blocking spyware, adware, and other software that call home to the Internet behind your back) as well as traffic from the Internet to your computer. The program works as a trial for 30 days and then reverts to the free version after that. This is a Windows firewall.

Filseclab Personal Firewall Professional Edition

This Windows firewall filters inbound and outbound traffic. You can configure which applications on your system is allowed to access the Internet, although by default, it automatically allows certain applications (such as those from the company itself, or those signed by Microsoft) outbound access without question.
