How To Browse Forums Without Logging -Googlebot
Googlebot
Googlebot is Google's web crawling bot (sometimes also called a "spider"). Crawling is the process by which Googlebot discovers new and updated pages to be added to the Google index.
Googlebot use a huge set of computers to fetch (or "crawl") billions of pages on the web. Googlebot uses an algorithmic process: computer programs determine which sites to crawl, how often, and how many pages to fetch from each site.
Googlebot's crawl process begins with a list of webpage URLs, generated from previous crawl processes and augmented with Sitemap data provided by webmasters. As Googlebot visits each of these websites it detects links (SRC and HREF) on each page and adds them to its list of pages to crawl. New sites, changes to existing sites, and dead links are noted and used to update the Google index.
How Googlebot accesses your site
For most sites, Googlebot shouldn't access your site more than once every few seconds on average. However, due to network delays, it's possible that the rate will appear to be slightly higher over short periods. In general, Googlebot should download only one copy of each page at a time. If you see that Googlebot is downloading a page multiple times, it's probably because the crawler was stopped and restarted.
Googlebot was designed to be distributed on several machines to improve performance and scale as the web grows. Also, to cut down on bandwidth usage, we run many crawlers on machines located near the sites they're indexing in the network. Therefore, your logs may show visits from several machines at google.com, all with the user-agent Googlebot. Our goal is to crawl as many pages from your site as we can on each visit without overwhelming your server's bandwidth. Request a change in the crawl rate.

How to Track Stolen Laptops With a .mac or IP Address
Computrace LoJack for Laptops states that more than 600,000 personal computers are stolen each year. When a laptop disappears at an airport or coffee shop, the greatest chance of recovery comes from preplanning. Installation of antitheft software offers more protection than trying to track stolen laptops with a .mac or IP address. Protect expensive equipment, personal information and confidential data by practicing prevention.

- Things You'll Need:
- Tracking software
- How to Track a Stolen Laptop With a .mac Address
Things You'll Need:
1
Notify your network administrator of the theft. Locating a stolen laptop using a .mac address isn't possible unless the thief gets on the same LAN. This makes recovery unlikely with the exception of a computer used on a college network. The likelihood is much higher if the thief is a student who will log on to the university network with the stolen laptop. In such a case, let the network administrator know of the theft. Supply the .mac address and the network administrator can watch for the laptop to log on to the network.
2
Forget about tracking a stolen laptop over the Internet using a .mac address. Tracking a stolen laptop using a .mac address is not possible over the World Wide Web. This second-level information is not passed through the router to the third-level ISP (Internet service provider).
3
Increase your chances of recovery by preinstalling antitheft software that "phones home" to a service provider or open source software such as Adeona. This allows the original owner to gain IP address information without contracting with a third party such as LoJack.

How to Track a Stolen Laptop With an IP Address
1
Contact your ISP (Internet service provider) to see if the thief has accessed the Internet using your service. The ISP issues a location-specific IP address when a computer accesses the Internet. If the owner of a stolen laptop obtains an IP address assigned to her computer since the theft, then the police can track its location.
2
Investigate whether programs such as Yahoo! Messenger or email software that automatically logs on at boot-up are still being accessed. Contact the service provider with appropriate police report documentation and a subpoena to obtain a recent IP address for a stolen laptop.
3
Install Antitheft Software to Track a Stolen Laptop IP Address
Use preinstalled antitheft clients to obtain a recent IP address for the stolen laptop. Supply the IP information to law enforcement.

1
Contract with a third party for antitheft protection. Computrace LoJack for Laptops offers a three-year antitheft guarantee for its software. Buyers subscribe to a service that uses installed BIOS firmware to track a stolen computer and supply recovery information to the police. Computrace LoJack claims to recover three out of four stolen laptops using its service.
2
Download and install an open source antitheft client. Adeona is a university-developed open source alternative to tracking services. There is no charge to install the software, which monitors and stores location data. Adeona claims superior privacy protection, as only the owner is able to access location data.
3
Check manufacturer service plans for theft protection details or call customer support. Some computer manufacturers, such as Dell, offer tracking, recovery and data deletion for stolen laptops.

- Install tracking software on all laptops, as .mac addresses are rarely useful in recovery, and gaining a subpoena for an IP address is challenging.
- Third parties may access the tracking information recorded by services such as Computrace LoJack to moniter a laptop owner's movements.
