I have already wrote how to upgrade port speed under Red Hat or Debian Linux. If you would like to upgrade or downgrade port speed under Windows 2003 server just use following guideline.
By default, most dedicated hosting service provider or your network administrator will provide you (hook you to) 10Mbps connection to Internet. If you would like to upgrade either of your port speeds to 100mbps or 1000mbps, you need to ask your network administrator to make port upgrade at network switch level. Once the network admin changed the port speed you need to make changes to Windows 2003 networking.
Please note that information outlined here also applies to Windows XP and other version of Windows operating systems.
=> Click on Start button
=> Open Control Panel
=> Select Network connections
=> Select the network interface (if you have multiple network cards) i.e. Local area connection #1.
=> Right click Properties
=> Click on Configure button
=> The driver properties window should open on screen.
=> Select the Advanced tab.
=> Select Link Speed & Duplex from the property list.
=> Select the Value tab to the right and set the port speed you are upgrading to WITH full duplex:
- For 10 MBS Select: 10Mbps/Full
- For 100 MBS Select: 100Mbps/Full
- For 1000 MBS Select: Auto
=> Select the OK Button.
=> Save the changes and close, the network related windows. It may take upto 1 minute for new settings depend upon switch and traffic.

- Linux Administration Certification (Red Hat, Suse)
- Unix Administration Certification (Soaris, AIX)
- Windows Administration Certification (NT/2000)
- Other programming certifications like C, C++, Java
- Here is the list of all IT certifications.
According to brainbench
Over a quarter million people participated in last year's Bench Games, Brainbench's certification competition. And they have listened to users requests and will be bringing back the Games in April 2006. Until then, to help you prepare for the Games, Brainbench is opening its entire library of certification tests...
So what you are waiting for try out yourself online
1) First try pining your own IP address to see if your IP address is set properly, syntax is:
If your IP address is 126.96.36.199 then try:
# ping 188.8.131.52
Tip use ifconfig command to see IP address for eth0 or any other interface.
2) Try pinging neighboring machines IP addresses:
# ping 192.168.1.2
# ping 184.108.40.206
If you need to setup/configure network or connecting to the network under Linux use following tools:
Under Red Hat use neat OR system-config-network (Fedora core) command
Uder Debian Linux use network-admin command.
You can also start above command from GUI. Using above GUI tools you should able to configure DNS, hosts, IP address etc. For more information see:
List of LINUX troubleshooting commands/tools part # 1
A firewall is designed to help protect your computer from attack by malicious users or by malicious software (viruses that use unsolicited incoming network traffic to attack).
Also before you disable your firewall, you must disconnect your computer from all networks, including the Internet to avoid damage :D
You would like to Halt linux firewall or stop linux firewall (i.e. flush iptables rules). First login as root user.
Option A - If you are redhat Linux user type command:
If you are using Red Hat (RHEL) / CentOS / Fedora Core Linux, use the following command:
service iptables stop
Option B - If you are Debian Linux user type following commands one by one
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
According to new artical "Sun gets very serious about Solaris 10 on x86 and the Open Solaris project that it hopes will nourish it, Linux vendors such as Red HAT and Suse had better get very worried". Well first of all Sunâ€™s support on x86 sucks. It works better on Suns hardware but not on the normal x86 hardware. Second if they really wanna get somewhere they need to correct that path stuff and include GNU utilities and they have much more to do. Read full artcial online.
