Admin resource: Use the right tools to manage your network

To be an effective network administrator, you don't have to be a scientific genius. And you don't have to memorize a bunch of obscure facts about hardware and software. Instead, you need to know two things:

• Where to find the appropriate solutions to technology problems when they arise


• How to use the right tools for monitoring, troubleshooting, and managing the activities of the various systems on your network

We know TechRepublic is the biggest IT community, which provides kinds of sources you turn to for solutions when problems hit your network. To demonstrate that TechRepublic is worthy of being a solutions finder, here I've compiled a list of articles that discuss tools you can use to improve the management of your network.

• Test-drive: Colasoft Capsa network analyzer
  
  Having good insight to your network is critical. There are so many potential issues that can be going on that any additional tool can be welcome. This can include attacks, transmissions and applications without encryption, or incorrect configurations bogging down the network.
  
  Recently, I had a chance to evaluate the Colasoft network analyzer or Capsa.
  
  
  
  


• Servers Alive is a valuable and inexpensive uptime monitoring tool"
  
  To handle a problem, you have to know that it exists. That's where a program such as Servers Alive comes in. It can e-mail, page, or call an administrator with an automated alert when a system goes down, a router fails, or a service goes offline.


• "Let Big Brother keep tabs on the health of your servers"
  
  Big Brother is another monitoring tool, but this one runs on Linux/UNIX (although it can monitor systems from other platforms). It's available free under an open source license.


• "PRTG makes it easy to monitor bandwidth"
  
  Bandwidth is an expensive and critical commodity for most organizations. PRTG (and its Linux/UNIX cousin, MRTG) allow you to keep a close eye on bandwidth utilization and quickly spot any potential problems.


• "Get two must-have network tools--for free"
  
  Here's a peek at two handy troubleshooting tools—HyperTrace and NetStatLive. Since these are small, easy-to-use, and free, there's no excuse not to try them.


• "Quickly manage systems over KVM with BgInfo"
  
  Most administrators who manage more than five or 10 servers usually have them loaded into a rack and access them with a KVM switch or remote access software. However, the more servers you have, the harder it can be to tell them apart—and making a configuration change to the wrong server can have disastrous consequences. BgInfo is a little tool that can help you set up desktop screens that allow you to quickly identify your servers.

Final word

Of course, this is not a comprehensive list of every tool you need to manage a network. It's just a sampling of the kinds of great tools that can make you more effective at spotting problems and getting them fixed in a timely fashion.

Business IM: Risks and Resolutions

Do your users use IM in your network? If I ask this questions, I believe above 95% network administrators will answer: Yes, of course.

MSN, Yahoo IM, Aol IM, Google Talk etc,with the rapid development of instant messaging tools,which are not just used for personal entertainment, but for workplace tools. However,according to a survey on the internet, most IM users are ignorant of its risks that may cause to the organization. Here we list the main Business IM Risks and Resolutons:



• Information leaks – Confidential materials, intellectual property, or proprietary information can be revealed, either intentionally or accidentally,through IM sessions or file transfers.

• Worms, viruses, etc. – Numerous malware programs target public IM systems and allow them to bypass standard firewalls and mail server antivirus systems.

• Network hacks and intrusions – Hackers use IM operating ports to bypass other security barriers and enter the corporate network unimpeded.

• Compliance, regulatory, or legal violations – Organizations subject to government oversight and compliance mandates may find themselves creating legal issues by failing to properly monitor, log, and regulate IM sessions and content.

• Productivity loss – Idle chat can disrupt employee productivity.

So many risks IM has, does it mean that we have to prohibit Instant Messaging in workplace, of course not, IM has its irreplaceable benifits other than other communication methods,as email, phone call, SMS. but we have some good suggestions to decrease the IM risks.

• Deploy network analysis tools like Colasoft Network Analyzer in your computer, to detect network intrusion attempts, monitor network usage, gain information for effecting a network intrusion.
  


• Regularly remind your users to update or upgrade their antivirus software
  


• Create written policies – Clearly and explicitly define acceptable and unacceptable use of instant messaging within the business environment.
