Yes, you can see it online. That is the purpose of setting up the no-ip software. The software ensures that the domain name maps to the correct IP as you have a dynamic IP address. This domain name then allows you to access your systems remotely, whether it is for serving web pages, an FTP server, or even remote login access to your systems.

In order for the port forwarding to work, the port numbers have to match. If you want to run your webserver on port 9999, then you also have to forward requests to port 9999 (you will also have to request that you connect on port 9999 such as http://mysite.no-ip.org:9999). If you want to run your webserver on port 80, then modify your webserver configuration to accept connections on port 80.

Since you get the router's config page (or something similar) when you try to access the domain name, you most likely have an option for remote access to the router set to port 80. Make sure that you have the remote access options disabled. You may also have to change the port that the router listens on for access to the configuration page (if you change this port, you will also have to request that port in order to get to the configuration page: http://192.168.1.1:325).

I checked out the Abyss Web Server. It does look like a very easy to use piece of software. Thanks for mentioning …

I have a similar router (WRT54GS v4) and have been very happy with it. All networking devices have their quirks, you just have to learn what ones your device has and how to fix it or work around it. If you are looking for more info about your router, you will be interested to know that your router is the same router as the WRT54G v4 with a different name.

The main known issue with the WRT54Gs is that they often choke when there are a large number of active connections. This often occurs if you use p2p software like BitTorrent but also occurs with other software.

The first thing you will want to do is upgrade to the latest Linksys firmware and see if that helps take care of your stability issues. If it doesn't, you have to option of running a third-party firmware like DD-WRT, which is what I run. The third-party firmwares give you more options when configuring your router.

Even though I have yet to understand the reason for this, I have found that my router got more stable after a few days of running. Mine had a few hiccups for the first week of running but has been rock solid since.

When you are facing problems like this, it is very helpful if you start with the simplest setup and build up from there. That way, you can more readily find out where your problem is.

I recommend taking the router completely out of the loop for the time being. Connect your computer directly to the modem, use the disk that your ISP sent you with the modem to setup the connection software, and connect to the internet that way. Let us know if you are able to connect using that setup.

Do you have the DSL modem and router properly connected? Run a CAT5 cable from the modem to the WAN connection on the router.

Do you have your username and password for your DSL connection? You must select PPPoE as the connection type in the router configuration and use that username and password in order for your router to be able to connect your modem to the internet.

Do you know what I mean when I refer to a web server? A web server is required for you to be able to serve web pages from your computer.

If you are running Linux, then you already have Apache, a very robost and secure web server, that you can use. If you are running a Professional or Server version of Windows, then you already have access to IIS, Microsoft's web server. Two web servers that will run on either Windows or Linux are Apache and lighttpd. Both of these web servers are available as source files, Linux packages, or Windows executables.

Other than just properly setting up and running your web server, you will also have to make sure that your router is forwarding requests on port 80 (the standard HTTP request port) to the machine that is running the web server.

As you can see, running your own web server is much more complex than just making an HTML file. It is not incredibly hard, it just takes some reading and a bit of patience.

You can try running DSL Reports Tweak Test. This can recommend some tweaks to optimize the connection.

Just to back up nizzy, I recommend doing as he suggests. That clicking sound is referred to as the "click of death" for drives and almost always is a clear symtom of a pending or current drive failure. nizzy's suggestion is the best possible solution to use in order to get some data off of that drive before putting it to rest.

Since you have a Dell, it may not be the best thing to set a BIOS password. If you ever lose that password, you have to have either replace the chip that handles passwords or have it professionally repaired. In other words, I suggest that you just put a password on all the user accounts on your system and force a log in each time Windows is started or comes out of a standby state.

In order to set a user password, click Start, select Control Panel, and select User Accounts. From there you can select a current account and change the password. If your system automatically logs you in each time the computer starts, simply click Start, select Log Off, and click Log Off from the pop-up. From that point forward, you will need to use your password to access the system.

The Windows password will completely prevent someone from gaining access into your system but will deter people who do not want to use special tools and some time to gain that access. It will also give you the ability to reinstall Windows or use special tools to reset your password if you ever have problems accessing Windows.

If you simply must set a BIOS password, know that if you lose it, you lose access to your machine until you drop $50-$200 to fix it. In order to set a BIOS password, you must first load your BIOS configuration. You load the configuration by pressing …

If you don't have access to the drivers on a disk, then you need to find out what your network device is and download the appropriate driver for it. You can find out information about your hardware by using Everest Home. Install that program on the system you need to identify the network device on and look at the hardware view. You should be able to find your device listed there. If the network adapter is a stand-alone card, look for the identity of that card. If your network adapter is built into the motherboard, you will need to identify the motherboard (you will get the driver from the motherboard manufacturer's site).

I assume that you are refering to the load averages that are reported on a Linux system. If so, the load average represents the average number of processes that are requesting CPU cycles (i.e. processes that are not in a wait state or dead) over the last minute, five minutes, and fifteen minutes. If your load is much higher than you want it to be, there are a number of possibilities on how to reduce it. If the processes are bottlenecking on RAM usage and you have a high swap rate, I would say that RAM would definately help you. If you don't have a RAM bottleneck and a high swap rate, your processor is the bottleneck. Putting a faster processor on the machine will help, but it may not be the best solution.

You can gain a lot more out of your current setup and reduce the load by optimizing your setup. Optimizing your webserver setup, database queries, database indexes, and complex code segments can create tremendous speed improvements. There was a time that I reduced the load drastically on one of our machines just by adding some much-needed indexes to our database tables.

Another possible bottleneck is your disk I/O. It's possible that your disk is causing much of the extended execution times of your processes. If this is the case, creating a RAID setup can improve your disk access times but can also add headaches of their own.

Depends on who is providing the DSL, what speed package they got, how long the cable that is servicing them is from the main switch, whether they configured everything correctly, and the quality of their internal wiring and the wire used to connect to the modem. As you can see, there are many variables. I also forgot to mention that their system can affect this. If their system is messed up somewhere, that can affect speeds.

How long has their connection been running since it was set up? Most DSL ISPs recommend letting the connection run fully for 72 hours so that the line can be optimized.

Have you contacted the ISP to request a line test? Sometimes there is a problem with the line that they didn't detect when they installed it.

So you have a dynamic-ip domain name... Do you have anything else? Do you know anything about how a web page is built or how web servers work?

I take it from your posts in the IP changing thread that you know a few things about dynamic IPs, but I have no idea if you know the basics of serving web pages. From your post it sounds like you have a dynamic IP domain name, the software for no-ip.org, a computer, and a desire to make a webpage but not much else. Please let us know what you know about serving web pages and what you want to use as your webserver.

What do you mean by "can't open the HD"? Do you mean that it shows up as unformatted? Does it give you an error when trying to access the data?

You mention that you like to play the latest games. Sorry to say, but your machine was not designed to run the latest games. At best, it was developed to do mostly non-graphically intensive productivity applications and older games or ones that don't rely so heavily on the GPU.

So if your main beef is that you can't run the latest games with a high resolution with all the options turned on, then there is little that can be done. If you want a high-performance machine, you need to do the research to ensure that what you get will fit what you want it to do.

As for your internet being slow even when there isn't anything running in the background, what browser do you use? And do you have any extensions, special plug-ins, or toolbars installed on it?

Usually a power light turning amber on any device indicates that it is in a stanby-mode (i.e. neither off or in operating-mode). Make sure that your system is actually off and not just in standby.

Did you try reinstalling the drivers for the network adapter?

The best advice I can give is to start reading the information that the code package includes. Most tarballed (.tar.gz packages) code packages include an INSTALL file in the base folder. You should start by reading that, it will tell you how the developer intended the software to be installed. If you don't find an INSTALL file, you will most likely find a README file that includes the installation instructions. I recommend that you read the README file even if there is an INSTALL file since the README file usually contains more descriptive information that may be important to know.

This post goes in conjunction with my post in your other thread.

I work as a web developer and maintain our servers as part of my job. I maintain one in-house Linux server and five remote Linux servers, so I know a few things about why Linux is great and what makes it a robust, secure platform.

How can a company make income from open source? Easy, charge for service and not for the product. Red Hat is easily one of the largest providers of Linux distributions. They currently offer two different version lines Enterprise Linux and Fedora. Enterprise Linux is not free, it is a professional, server-grade package that you purchase a subscription for. Technically, you are not purchasing the software; rather, you are purchasing access to their support, automated updating system, and management controls. Fedora is free, it is a community developed package that is moderated by the Red Hat team. Even though Fedora is free, you can still purchase services from Red Hat, such as: support, installation media, manuals, professional installation, access to their up2date service, etc.

The examples I gave are some of the primary ways that companies can make money from open source. It's not always about making money though. Much of the time the company is able to make a much bigger name for themselves by giving the software they produce away for free. Since the software is free, many more people will use it, talk about …

There are Linux antivirus products. There are just far fewer Linux antivirus programs when compared with antivirus programs for Windows. There are a few reasons for this:

• Virus writers want attention. Since most people that interact directly with the OS interact with Windows, why not make a virus to infect Windows since you will annoy the most people?
• Stereotypically, a larger proportion of Windows users are vulnerable to making mistakes that allow viruses to infect their system when compared to Linux users.
• Windows is more vulnerable to attack. This is a very debatable topic, but it is widely believed that there are more exploitable holes in Windows than there are for viruses.
• It is also argued that potential holes are found and patched in Linux versions faster than in Windows versions because of the fact that more people look at, analyze, and test the actual code that builds Linux distros and much of the software that runs on them. This is due the the fact that most of Linux software is open and able to be viewed by anyone.

It should be noted that while Linux doesn't suffer from most of the software considered to be viruses, there are still large batches of software that "infect" Linux machines. The worst kind of software to get on a Linux machine is a rootkit. Rootkits allow someone to gain top-level system access and control while not alerting the actual users of the system that anything has changed. These rootkits …

Catweazle is correct that there is very little that software alone can do. A company that I have been a customer of in the past and am currently partnered with at work (I work for a company that develops websites for churches) is Integrity Online. They offer a variety of services from filtered internet access to free accountability software (tracks and reports access to potentially inappropriate content). The nice thing is that their internet filters aren't mindless programs; rather, they are filters that are actively monitored and maintained by the company.

Do you have a number of different USB connection locations on your machine?
If so, where are they?

Which ones are you using to connect your devices to?
Does connecting these devices to different ports result in the same message?

Are you wanting to add a password to your Windows login so that Windows asks you for a password or are you wanting to add a password to your BIOS so that your system won't even startup without the password?

If you want it to automatically log you in as it did before, do as follows:

• Click Start, select "Run..."
• Type "control userpasswords2" and click OK.
• Put a check in the "Users must enter a user name and password to use this computer" and click OK.
• Follow the instructions on any pop-up dialog boxes.

I have no idea why they made it so hard, but that is the easiest way.

Just asking? Why would you think of such a question unless you suspected Windows of deleting a file without your request for it to do so? If you have files that are mysteriously disappearing, either you have some malicious code (i.e. virus) or some malicious person (i.e. child, roommate, sibling, person with access to your files through the network, etc) accessing your files.

Poser uses a large amount of resources since it is a very processor-intensive 3-D modeler. Even top-of-the-line machines will slow under the demands of Poser. When Poser first starts, it will take every spare bit of processor time that it can to load everything up and get the program running. So if you notice that all your background tasks suffer slowdowns when the program loads, that is quite normal.

When you say, "I have to shut off alot of processes to get it to work", what kind of processes are you talking about, and are you saying that that Poser refuses to run unless you shut down those processes?

If you have to shut down background processes/programs in order to use Poser without Poser feeling extremely slow, then most-likely your system isn't fast enough to multitask Poser and those other programs.

Burn yourself a copy of the Ultimate Boot CD. Boot your system using that disk and use the Offline NT pw & reg-editor program on the disk to reset the Administrator password.

I've used this tool myself, so I know that it works. Make sure you read the instructions thoroughly to avoid potential mistakes.

Hi , i am rahul and i am new to this forum. i have netgear router and since last two days the net is really slow so yesterday i resst the router and net went completely down. when u connect my yahoo dsl modem direclty to my desktop it works great but through my wireless router there is no network connection.it noly shows the packets transfer but i cannot surf the internet. plz help

Rahul

Please don't add comments to someone else's thread unless it is on the same topic. Since your concerns are completely different from scott.sumner1's, please make your own thread to request assistance. Once you do, we will help you.

What graphics card is it?
What kind of connection does it have?

Did you try putting the original harddrive back in the machine?

Can you load up your router configuration screen from your browser?

As nice an idea as that is, unfortunately there are just too many sites to block. If you block the sites that he goes to frequently and he truely has an addiction problem, he will most likely just end up going to another poker site. I don't believe that this is an issue that you can resolve with tech.

Keeping all that in mind, it is possible to prevent sites from loading up properly based upon their domain name. Check out information about creating a Hosts file.

Reset your router back to factory defaults and then run the wizard again.

If you are on a broadband connection that goes through a router, you might want to check your router setup. Sometimes routers have parental controls that allow for site blocking.

There are some other options, but it would help to know why you want to block access to the site. Who do you want to prevent from accessing the site? How much technical knowledge and system access do they have?

Short answer
Yes, it would be very unwise.

Long answer
"I feel that I am properly protected without it". What do you base these feelings on? Do you base it on research that you have done that indicates that your software solutions are just as good at protecting your machine from attacks without NAT protection as they are with it? Do you base it on a full understanding of how attacks are made, how they can be guarded against, and the differences between hardware and software solutions against these attacks?

My words may be harsh, but my point is valid. Unless you are a security software and hardware expert, you have little idea of how complex attacks can be and how vulnerable your machine truely is without layers of comprehensive security. How do I know this? I'm an IT professional. I maintain a number of web servers, and I see how our boxes get attacked all day long. The more I have learned about how attacks work and how they exploit weaknesses in security, the more I realize that I know very little about the intricacies of designing and maintaining software and hardware that will offer the most protectection possible against all foreseeable attacks.

The way I think about it, there are four main lines of defense in computer security.

The first line of defense is your hardware. Think of the hardware security as being an armored fortress. It may not protect you from …

Visa has implemented new rules on handling credit cards. Unless you want your server and all your code to be subject to an audit by the credit card companies, you do not want to store any credit card info on your server.

There are two main ways you can use a payment gateway like ECHO.

The first way is that you can send the visitor to a secure form that is hosted on ECHO's servers that will take all the payment information and give a response back to your server on whether or not the transaction was successful. This method makes it easier on you in terms of offering a secure payment system for your customers since all the credit card security is handled by the payment gateway.

The second way is that the gateway offers you a program that you can send data to, which responds with the approval or denial code and a response message. It's fairly easy to set this up with ECHO. They even offer sample code that will help you build the form and the form data processing code. This puts a lot of the burden on you and your system. You will have to make sure that you are not storing any of the purchaser's credit card information and provide a SSL connection for the form so that the data transmission is secure.

You need to get a payment gateway. I recommend using ECHO. I have worked with them with a few clients and have been very pleased. They have a variety of solutions that you can use. I recommend that you check them out. If you have any questions, let us know.

If you are going wireless, have you gotten your wireless router yet?

As for the issue with your computer, have you tried turning off the router, turning off your computer, disconnecting the USB cable on both ends, connecting the CAT5 cable, fully starting up the modem, and then powering on your computer?

I'm by no means an expert, but I have had my fair share of experiences with setting up and maintaining networks. Anything I say should by no means be considered comprehensive and may not even be completely accurate. The best I can give you is a hypothetical conversation that shows how needs can be assessed allowing for the beginning of a network design.

I'm setting up a computer lab for my students to use. What do you recommend?

There are a lot of things to consider when building a network. Let's see if we can't narrow down what type of needs should be addressed. How many computers will be part of this network?

The max class size is 30 students. The teacher of the current class will need a computer. We'd also like some additional computers available for the teachers and for other students who may need to finish up projects. Taking all of that into account, I'd say that we will have a total of 41 computers in the network.

Will there be any other devices attached to the network? Other devices can be printers, network attached storage or a file server, Voice Over IP devices, or any other device with a network connection.

I'm glad you asked that. We will need to have at least two laser printers on the network.

Will this network connect to an outside network such as the school's main network?

It will connect to the rest …

See if you can find it listed in the Disk Management console.

Run Nero's General CleanTool to remove all the files and registry entries.

DJSILVERMAN, there is not an easy fix for you.

The best way to fix your problem is to contact Dell tech support. You will have to prove that you purchased the machine for them to help you. If you bought it from someone else, you may have to do a transfer of ownership. Their support can provide you with the master password for your machine based upon the Service Tag on the machine.

An alternate solution is that I have a piece of software that may allow me to find that password for you. Can you tell me what your service tag is (make sure you tell me the complete service tag)?

What problem is your friend experiencing that is preventing her son from playing his games? I have never heard of any software that requires the partition that it resides on to be a specific file system. NTFS doesn't change the files, it just changes the way they are stored on the disk.

I've never known RAM to be a limiting factor with how much harddrive space can be addressed. In a broad sense, motherboards can be a limiting factor. In reality, it is the BIOS that limits the space a board can address.

If your motherboard has a BIOS that limits the size that can be addressed on a partition, it is possible that the manufacturer created an updated BIOS that you can flash to in order to add large partition support.

I agree with MartyMcFly. Check your Disk Manager to see if you can format the remaining portion of the harddrive to an additional partition.

Bus networks are very inefficient. In order to ensure successful data transmission, each machine must monitor the network and wait for just the right moment to send the data. Then it must monitor what is occuring during the data send in order to see if there was a data collision. If there was a data collision, then it needs to decide how to resend the data. As you can see, very inefficient.

Switches have built-in logic circuitry that acts as a traffic controller. Essentially, it can tell all the traffic to stop and allow one port to send data through to the other port. This is why the devices are called switches; they switch where the data goes depending on where it is supposed to go, similar to how railroad switches connect different sections of track. Some switches are so "intelligent" that they can allow multiple ports to send at the same time. In other words, if port 1 wants to send data to the machine at port 5 and a machine on port 3 wants to send data to port 2, these switches can allow for both of those data transmissions to occur simultaniously. As you can see, switching technology was a giant step forward in the efficiency of networks. It takes the burden off of the individual machines and puts it on a single devices.

Something else that I haven't mentioned is that the bandwidth across a hub is shared whereas the bandwidth across a switch …

Get Nero's General CleanTool program. This should be able to remove all the files for you.

Change all your settings to Automatic. The router will handle giving the different computers IP addresses.

The reason that I asked is that this problem occurs often when the time zone settings are incorrect. You'll set the time manually and the system will reset it while connected to the internet, causing the time to be shifted some multiple of an hour.

Get a broadband router. You can get this at most stores that carry computer equipment. If you just want to connect both using CAT5 cables, get a standard wired router. If you would like to add wireless capabilities at some point, go ahead and invest in a wireless router.

I haven't worked with too many routers, but I have worked with a wired Linksys router that never gave me any trouble and a D-Link wireless router that makes me want to break things, mainly the router itself.

Unfortunately, this message means that crucial files needed to run Windows have become corrupted or are missing. You will most likely need to reinstall Windows. You can do an "in-place" install by booting from a Windows XP install disk and selecting Install. This will result in you needing to reinstall most of your software, but your data files will remain.

It's easy to make a standard internal drive and external drive. Check out the enclosure options offered at Newegg. If you have any questions about them, just let me know.
