Loopback failed - blocked - web page test not possible

I want to use the address "localhost" for testing web pages. However localhost is blocked despite of is incribed in the hostsfolder. I can ping my PC but I cannot connect using the telnet option. However I can open with telnet the Prestige Menue. I suppose I have to configure something there to enable loopback.

If the first one does not, but the second does, it is possible that the issue can fixed simply by selecting.
IE-->Tools-->Options--> Connection --> LAN Settings Check Bypass Proxy for local addresses

If you can't telnet into your computer, make sure you have the Telnet service running :

  1. Click Start, then Run, and type "services.msc" (without quotes) and click OK.
  2. Find the "Telnet" service, right-click and select Properties, select "Automatic" instead of "Disabled" in the startup type box.
  3. Click Apply.

Web page performance is a measure of the response load time of a web page. The slower a page loads, the higher the page's visitor bounce rate will be. There are quite a few free tools available on the market designed to conduct diagnostic performance tests on web pages. These tests analyze a select page, based a set of rules that are proven to speed the load time. You can use a web-based performance analyzing tool. Or you can install tool add-ons to your Firefox web browser.

Open your computer's web browser and go to or Enter the complete URL of the page you would like to measure in the provided field. Press "Enter" to get the results of your performance test. b> Using Page Speed Firefox Add-On b> Launch the Firefox web browser. Download and install the Page Speed add-on from the Google website. Download and install the Firebug add-on from the GetFireBug website. Enter the URL of the web page you would like to measure in the Firefox address bar. Click the Firebug icon located in the top right-side of the Firefox window, to open the Firebug window. Click the "Page Speed" button in the Firebug status bar. Click "Analyze Performance" to get the results of your performance test. b> Using YSlow Firefox Add-On b> Launch the Firefox web browser. Download and install the YSlow add-on from the Yahoo website. Download and install the Firebug add-on from the GetFireBug website. Enter the URL of the web page in the Firefox address bar.

Cannot contect to apache through wrt54g

Highly unlikely. That would block all HTTP sites that use Apache. Even then, how would they distinguish one web server from another type. Your error is based on a specific site, or all internet if Comcast does not show their splash page saying it can't reach a specific site.

In my system some of the sites are not open

Dear i have send some information for solve your problem.
i hope you have satisfied my help.

Fix 1: Check your Windows HOSTS file - Make sure there’s no entry in the hosts file that maps the website’s address to localhost or an incorrect IP address like – it is a possibility if you have imported some third-party hosts file.
cmd /k notepad c:\WINDOWS\system32\drivers\etc\hosts

Fix 2: Find Faults in the Pipeline – Paypal website may be up and running but it is possible that the real problem lies with a router that is between you and the computer hosting the Paypal website. Do a traceroute and check for messages like “Request Timed Out” – they will help you find the location of the breakdown.
Type the following command in the Run Window:
cmd /k tracert – remember to replace Paypal with address of the website that is unreachable.
Fix 3: Clear DNS Cache – The DNS cache keeps a record of sites that you have recently visited on your computer. If that gets corrupted, you may have issues opening sites that were previously accessible without problems.
Type cmd /k ipconfig /displaydns in the Run window to see the cache entries. If that unreachable website is listed in the cache, type cmd /k ipconfig /flushdns to clear the cache.
Fix 4: Website May Be Blocked – The chances are rare but it is possible that access to some particular website may be have been restricted by the Office firewall. To test this, send an email to with the problematic website URL in the subject field. If the website is up, you will get a text copy of the web page in an email message.
Fix 5: Suspend the Anti-Virus and Firewall – If you are running an external software firewall or anti-virus program (like Norton, ZoneAlarm, etc), exit and restart the web browser. Is the problem solved now ?
When nothing works, open and reboot the modem. If that fails, restart your computer and as a final step, call your ISP support.

I am trying to use Joomla on my own computer and can not access the ''local host'', I have installed Xampp, am using windows vista, have a router between me and the internet.

To access "localhost" you must have a web server ( IIS or Apache - IIS is the simplest and is found in add/remove programs, Windows components usually) running on the PC that Joomla is installed on. You must also use http://localhost for it to work. Localhost means you are only doing a loopback to your own pc for testing purposes. By default most web servers run on port 80 if the port is changed then you must use "http://localhost:port". Depending on how your network is set up - If you have a router or firewall you may also have to "open" or do a port forward to port 80 for the software to see the server holding the Joomla pages and also allow internet access as a server. First try the default web page the server has usually default.htm or index.htm as http://localhost/default.htm etc, if it loads then you know localhost is functioning, then try the Joomla page you want to see using it in place of default.htm. If no page loads at the start - then check your Apache(Xampp) configuration file to be sure it is set up and working properly - if I recall it is hhtp.conf open it with notepad to configure and save as "all files" not text. You might also check your Joomla configuration options as well to be sure the correct port and location are used for serving pages.

Where is the serial number on an HP Officejet J6480 All-in-One printer

Usually the serial number can be found either in the back or in the bottom of the printer.

If your printer is working you can print a self diagnostic page which would have the serial number.

To print the Self-Test Diagnostic Page
• Device control panel: Press Setup, select Print Report, select Self-Test Report,
and then press OK.
• Toolbox (Windows): Click the Services tab, and then click Print a Test Page.

Installing IIS On Windows Xp Pro

If you are running Windows XP Professional on your computer you can install Microsoft's web server, Internet Information Server 5.1 (IIS) for free from the Windows XP Pro installation CD and configure it to run on your system by following the instructions below: -
1. Place the Windows XP Professional CD-Rom into your CD-Rom Drive.

2. Open 'Add/Remove Windows Components' found in 'Add/Remove Programs' in the 'Control Panel'.

3. Place a tick in the check box for 'Internet Information Services (IIS)' leaving all the default installation settings intact.

4. Once IIS is installed on your machine you can view your home page in a web browser by typing 'http://localhost' (you can substitute 'localhost' for the name of your computer) into the address bar of your web browser. If you have not placed your web site into the default directory you should now be looking at the IIS documentation.

5. If you are not sure of the name of your computer right-click on the 'My Computer' icon on your desktop, select 'Properties' from the shortcut menu, and click on the 'Computer Name' tab.

6. Your default web directory to place your web site in is 'C:\Inetpub\wwwroot', but if you don't want to over write the IIS documentation found in this directory you can set up your own virtual directory through the 'Internet Information Services' console.

7. The 'Internet Information Services' console can be found in the 'Administration Tools' in the 'Control Panel' under 'Performance and Maintenance', if you do not have the control panel in Classic View.

8. Double-click on the 'Internet Information Services' icon.

8. Once the 'Internet Information Services' console is open you will see any IIS web services you have running on your machine including the SMTP server and FTP server, if you chose to install them with IIS.

9. To add a new virtual directory right click on 'Default Web Site' and select 'New', followed by 'Virtual Directory', from the drop down list.

7. Next you will see the 'Virtual Directory Creation Wizard' from the first screen click the 'next' button.

9. You will then be asked to type in an 'Alias' by which you will access the virtual directory from your web browser (this is the name you will type into your web browser after 'localhost' to view any web pages you place in the directory).

10. Next you will see a 'Browse...' button, click on this to select the directory your web site pages are in on your computer, after which click on the 'next' button to continue.

11. On the final part of the wizard you will see a series of boxes, if you are not worried about security then select them all, if you are and want to run ASP scripts then check the first two, followed by the 'next' button.

12. Once the virtual directory is created you can view the web pages in the folder by typing 'http://localhost/aliasName' (where 'aliasName' is, place the alias you called the virtual directory) into the address bar of your web browser (you can substitute 'localhost' for the name of your computer if you wish).

Rtl 8139D drivers for Red Hat 5 enterprise edition

I have no choice and open terminal then type “init 0′ (shutdown) :D. Then switch back to Windows XP to find the type of driver I need to install on Linux RHEL 5 and find solution over the internet. Noticed that I am using Realtek RTL8139/810x for NIC on Windows. After that, quickly go to the internet to find “how to install Realtek RTL8139/810x on Linux RHEL 5“. Then, I found that many crappy thing and **** suggestion over the forum. I read almost all Linux forum and follow all the sugesstion included to use ndiswrapper to install that Realtek NIC driver. But it doesn’t work on my machine. Yes I confess that I am new in this matter and perhaps ndiswrapper is too advanced for me.
Then, I have decided to try and error. I go to Realtek official website to see if I can get the specific driver for Linux. Found that:
all at the same download page. Then I made I my own conclusion that, Realtek8100 or Realtek8101 can be use as well since I can’t find any RTL8139 driver for linux over the internet. Too not wasting your time to read my crappy story, then download this driver over HERE. DOWNLOAD DRIVER HERE, before that make sure you login as root. After download complete, just write the following command on your terminal:
[root@localhost ~]# cd Desktop (i put the file on Desktop)
[root@localhost Desktop]# tar xvvf r8101-1.001.00.tar.bz2
[root@localhost Desktop]# cd r8101-1.001.00
[root@localhost r8101-1.001.00]# make clean modules
[root@localhost r8101-1.001.00]# make install
[root@localhost r8101-1.001.00]# depmod -a
[root@localhost r8101-1.001.00]# insmod ./src/r8101.ko
[root@localhost r8101-1.001.00]# lsmod | grep r8101
r8101 28688 0 <—if this appear, then you’ve installed the driver successfully:)
Then check if your ip have configured correctly or not
[root@localhost r8101-1.001.00]# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:1C:25:4D:9A:0A
XXXXX XXXX MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Interrupt:177 Base address:0×2000
lo Link encap:Local Loopback
inet addr: Mask:
inet6 addr: ::1/128 Scope:Host
RX packets:1611 errors:0 dropped:0 overruns:0 frame:0
TX packets:1611 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:4526976 (4.3 MiB) TX bytes:4526976 (4.3 MiB)
sit0 Link encap:IPv6-in-IPv4
NOARP MTU:1480 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Since you can see the ethX which X is 0,1,2,3 (mine is eth0)…. instead of just lo and sit0, then its working now. NIC driver has been installed successfully.
Finally, on your terminal type:
[root@localhost ~]# system-config-network

You can see on hardware tab there are Realtek Semiconductor with status ok. Then, move to Devices tab, and click New > Ethernet connection > Forward > Choose REaltek Semiconductor…. > Forward > then up to you whether want to set DHCP or set static IP.
Now you can open Firefox or Konqueror and start browsing internet happily:)
[p/s] If check again on your terminal with ifconfig -a it should return your local ip address under the eth0 which is 192.168.1.* ; * is 2-255
