The Nimda Virus...



Because of the increased activity over the Internet, viruses and worms have become serious pests. As the Internet advances, these pests are becoming much more sophisticated. There capacity to spread across the Internet in just a matter of hours can cause serious floods of payloads to systems. One recent virus that caused, and still is causing, an up-roar across the Internet is the 'Nimda'.

What is Nimda? Nimda is a computer virus appearing first on September 18, 2001 when it caused massive delays by creating huge amounts of traffic as it spread across the Internet. Nimda has four main attach mechanisms: web server to web server (IIS 4 / 5), to desktops through an e-mail attachment called README.EXE or ADMIN.DLL; browsing infected Web sites from Windows desktop or server machines; and by shares across internal networks. Once an internal machine is infected, it is possible for the virus to spread to shared drives and machines.

Changing Web Hosts? Know-How With This Step-By-Step Guide

Contributed By Boris Mordkovich, Director of Operations at MordComm, Inc. (HostVoice | AdWatcher | PPCUniverse)


Every webmaster cringes at the thought of moving hosts. Like moving your home it can be messy and sometimes problems arise. But if you follow these simple steps, your move will be less painful.

Backup Backup Backup
If you've been diligent with your backups, you've got a lot of insurance to fall back on yet always make the latest backup. If you haven't, before you do anything else, do a backup now. Backup anything and everything you can and don't forget your database if your site relies on it. Save at least 2 copies and store them separately. One for you to work with, and the other as an archive. Do not underestimate how easy it is to copy over these files as you make changes or simply mess it up.

If you're moving to a host who has as different control panel, make a manual backup by downloading all your files because different control panels may not be able to restore the backups made by your old host. They also have different directory structures so your file trees will be in a mess. If you need to, make a small note file with notepad with memos for you to remember the old server configurations. This will help you as you make changes on your new host server and save the confusion moving back and forth between hosts. Remember to make the correct transfer type (ASCII or Binary) as you download. If your download is not right chances are you'll have a tough time getting your site to work on the new host server.

If server logs are especially important, remember to backup those too. There is no good way of moving logs yet because different hosts may log statistics differently. So the best thing to do is to download it and use a log analyzer on your computer to make references to later on.

Gather Odds & Ends
1. A Good FTP program which you should have by now
2. Get your new host server's DNS
3. It's also helpful to have a script that tells you the server environments installed on your new host server for quick references.
4. Get the temporary URL on your new host so you can check your site before you make a DNS change.
5. If you have your host control the domain inform them not to change your DNS until you tell them to.
6. If you run scripts:

  • Get a copy of the original installation guide and the script. Sometimes after moving the scripts just do not work right so you might need to install the script from scratch.
  • Get a list of all the server paths such as Perl, Sendmail and home directory on your new server.
  • If your script needs special server modules or programs ensure they are installed and where. Even though these might be covered before you ordered the account with the host but sometimes your host has removed it or haven't installed it yet.

Inform Your Visitors
It is common and good practice to inform your visitors and customers of the server move. If you run a e-store, this helps assure your customers you have not fled with their money if there is any downtime. Also give an alternate email so you won't lose emails in the transfer. You might also want to give periodic updates prior, during (if there is downtime) and after. If your site is large, doing this is helpful because your visitors can alert you whenever there is a part of the site not working.

Moving Day
Try to schedule the move at a time where there's least traffic. Backup again just before you do the move so you'll have the latest data. Start by first copying or creating your custom error pages onto the new host server. Put a small note in there about the move. You can always remove it later. Then upload the most visible parts of the site first i.e the main pages then move on to the less critical parts of the site. If you have a large site with many divisions you might want to split them across different days and instead move the least critical first. Just ensure you always do a backup before you do any moving. Use the temporary URL to check your site, visiting as many pages as you can.

Changing DNS
Once you're satisfied, change your DNS over. This typically takes about 24-48 hours so you have time to make some minor changes if need be. You might want to also take this time to modify your old site's error pages to inform your visitors of the move and give a new URL if there are URL changes. To help you determine if the DNS has resolved, make a small change on the new pages to differentiate between the old and the new.

Monitor
After you've moved and the DNS resolved, do not release the old account yet. Keep it as long as two weeks running concurrently. Go back and check the old servers for activity. Check your old email account and if you have a web based contact method on the old server check to see if any communication is left there. Once you're comfortable all email and traffic is correctly directed to the new host server, you can cancel that account.

Web Hosting: Selecting the Right Host!


Choosing a web hosting company is a very personal decision based on your own unique needs. Web hosting is what places your website into the World Wide Web, where anyone can access to it 24 hours a day. In other words, without placing your site onto a web hosting service, you won't get the visibility you want. Most small business owners will most likely go through a web hosting company rather than invest in acquiring their own servers, which is very expensive and difficult. On top of the expense that is involved with having your own server, you need to have a strong educational background to be able to deal with the technical aspects of implementing your own server, or having your own technical computer staff on hand to deal with the process. (And those programmers don't come cheap either!) If you're a new online business or looking for ways to expand your market reach, web hosting is definitely the way to go.

Which web hosting service do you select? There are two key things to keep in mind when you begin your search for an appropriate web hosting service: (1) Find a web hosting company that meets your needs for today, (2) Make sure that this web hosting company you choose can grow with you as your business expands. Another important factor you want to know up front about hosting services, is that once you choose one, and decide it doesn't pan out for you, to switch to another service will be a very painful and a lengthy process. It's just not worth the mistake to make!

Check out these tips in how you can select a web hosting service that has the most qualities such as flexibility, service, and growth capabilities along with a strong background in technical abilities that you're seeking, at a price you can afford.

Shop and Research Do your surfing on the net. Shop around and compare the services between the different web hosting services. Ask other businesses what hosting companies they're using. Make sure you check out businesses that have made statements in testimonials about the particular web hosting company they're using. Follow up by contacting them and have a series of questions to ask, and see how they respond to your questions in regards to those services. Still don't know where to start? Check out the web hosting directories on the net, which will save you hoards of time, because the real good ones will be the ones on the first, few pages, www.webhostingrebates.com could be a good place to start.
