Host laptop carries Windows XP n other one is having VISTA HOME..
I m able to share n browse both laptop contains in both laptops but the problem is i m not able to browse INTERNET in the one carrying VISTA.
So what is missing in Internet Connection Sharing ???
Host laptop (Sony VAIO)carries Windows XP n other one(HP Pavillion) is having VISTA HOME..
I m able to share n browse both laptop contains in both laptops but the problem is i m not able to browse INTERNET in the one carrying VISTA.
I m using Motorola SURFboard SB5101 USB cable Modem to connect the net in XP based sony laptop n connect the other one (HP Pavillion) through modem s well using lan cable…
So what is missing in Internet Connection Sharing ???

Well it is not a big deal, in case I’ve already shared files and folders. But let me just warn you that sharing the connection means, technically half of the total bandwidth speed. But sharing it within the 2 computers/Laptops will result in much more loses. bu the details you provided are not sufficient to guide you step by step procedure. but in short. First of all, You need to assign IP addresses manually to both of the laptops (just assign manual IPs to the LAN connection connecting these 2 Laptops. Now on the Laptop-2(without internet connection), try to ping the Ip address of the Laptop-1 (with internet) in gateway of laptop-2, put the Ip of the Laptop-1. Note down the DNS address from Laptop-1’s net connection, put them in the the DNS of the Laptop-2. And finally share the internet connection in the LAN of the Laptop-1. I know it sounds confusing. But it is the best way for you without spending anything, except your BRAIN. good Luck

My sister wants an external hardrive for her laptop for Chrismas….
My boss suggested this website, and it all says desktop external hardrives. But just wanted to check, they are OK for laptops.

My sister will only really be storing music and film and the occasional work thing. So do you think this one would be OK?

Thanks for advice and any tips!

Most external hard disks connect via USB. Some use Firewire (1394) and some eSATA. USB is by far the most common, and Firewire next most common.

Any external hard disk called "Desktop" will work fine with your sisters laptop as long as you buy one that uses a port type her laptop has. There are very few laptops that don’t have USB. You’re best bet is to make sure her laptop has USB and get a USB external hard disk.

Also, make sure the external disk supports USB-2.0 (sometimes called High Speed). There are still some USB-1 disks selling and they are so slow they will drive your sister crazy if she’s playing with audio and video files (large).

Some external disk require external power (plugs into an AC outlet). For a portable laptop application this can be annoying (in class or on a airplane. etc.). If it was me I’d get her one that doesn’t require external power.

How do I prevent unauthorised laptops from accessing the wired lan network – the wired lan network has about 10 machines on it – 9 desktops and 1 laptop. I want to prevent unauthorised laptops from plugging in physically to the network – by removing the CAT 5 cable and plugging in the same to the laptop – and then accessing information on the entire network.

The best way to protect your network is to use explicit access control based on Media Access Control (MAC) addresses that a uniquely identify each network interface. Most broadband routers have such access control feature readily available, but the degree of simplicity to configure and enable them depends on make/model and firmware revision of the router. You’ll need to consult the documentation for specific instructions for “Access Control” and/or “MAC Filtering” for wired and wireless services.

Securing the wireless portion will be relatively easy: Choose the most advanced algorithm and the longest encryption key possible. WPS is the latest and simplest technology (pretty much all systems made in the last 2 years support it), followed by WPA2 and WAP (which has 1 known vulnerability that occurs only in 1 specific type of configuration). Avoid WEP – it’s relatively easy to crack (but it’s better than nothing, as outlined in the article “Securing your wireless network” listed in the sources below).

I would suggest the following measures:

1.Change the administrator password to a non-default password.
2.Don’t broadcast your SSID (so it won’t show up in a network list).
3.Change channel from default (unless your router is capable of sensing conflicts).
4.Reduce your Wifi transmitting power (reduce the area of coverage to a minimum).
5.Use MAC filtering for access control.
6.Use the most sophisticated encryption available.
7.Use a non-default IP address range (e.g. 192.168.121.x or 192.168.137.x is better than 192.168.0.x or 192.168.1.x because these ranges are harder to guess)

For the wired ports, things are a bit more complicated (and again depend on make/model and firmware revision of your router and switches): There is usually less security on wired connections because of historical evolution and an assumption that physical access can be limited to trusted people. So, let’s start with physical access: Put all routers, switches and modems into a lockable room (or a lockable cabinet with sufficient ventilation). Try to protect CPUs and wall outlets so that there is no easy access (i.e. expose only keyboard mouse and monitor and hide the CPU and network connections in cabinets).

If you cannot physically protect the network connections (i.e. somebody can unplug a cable either at the computer or a wall outlet), you can implement some logical measures but these are somewhat limited with consumer-level hardware (because of costs and the fact that such devices are meant to enable access rather than prevent it). In some cases, routers also apply the above mentioned MAC filtering rules to wired connections. This would be your first line of defense.

However, on hubs and simple Ethernet switches, the data traveling on the wires can be seen by all devices on the network. This makes it relatively easy for a cracker to install a packet sniffer, look into the traffi and learn what devices are attached. The cracker then can configure his or her system to pretend it was a legitimate system – a process that is called “spoofing.” That’s why in high-security environments use more sophisticated ethernet switches (for example the Cisco 3550 series) that enable and disable physical ports and authenticate attached systems and their users based on access control systems like Tacacs+ or Radius. Taking advantage of such features requires authentication servers and software installed on the client systems that deal with the challenge/response mechanisms (additional hardware and software = additional costs).

Security is a trade-off based on a cost/benefit analysis (how much security do you need and how much time and money are you willing to spend on implementing and maintaining it compared to how much you could actually lose in terms of stolen data or stolen services). By the same token, cracking networks is also subject to a cost/benefit analysis: How much time and effort is a cracker willing to spend to intrude a network.

At the end of the day, no security measure is perfect and all networks can be cracked. It’s sensible to protect yourself by setting the bar as high as possible. So, I hope my answer provides you with some insights and guidelines for securing your network as good as possible with what you already have.

I want to know how many laptops are allowed per head when we are travelling from US to India. I have to carry two laptops with me. So can some one tell me, if it is allowed to carry more than one laptop? I doubt if the US customs or India customs will object if I carry two. If it is not allowed, can you suggest me how I can bring those two laptops to India? Thanks in advance.

as many as you can carry. You have a weight allowance and it is up to you to use it, the airlines don’t care what you have as long as it meets the regulations

My last business trip I carried my laptop, an LCD projector, a 2 way radio, and my mobile phone. The only one who cared how much electronic junk I was carrying was security when they wanted to test for bomb residue (Irish Terrorist) and if my laptop works. One of my colleagues regularly travels with at least 2 laptops and sometimes 3 domestically and has never had a problem except for paying for extra baggage (the boss hates when we do that). For my two cents worth Indian customs may have a problem with it BUT most likely they won’t .

Have a good trip and safe home.

Okay, I have one Vista laptop connected to a Buffalo router via wired connection (it can be wireless if need be) and one XP laptop connected to the router via wireless connection. I’m sure it’s something simple that I’m missing, but how do I get the two laptops communicating with each other for file sharing? I have a buch of stuff on my old XP laptop that I want to send to the new Vista one, and it would be really nice to do that via a network instead of copying it all to flash drives!

(This is for XP, don’t have Vista, but hopefully it is roughly the same)

1. Double-click on the "My Computer" icon.
Go up a level (third icon from the left), then open "My Network Places".
Hopefully it will show the other computer as an icon.
Open this, and hopefully there will be a shared folder where you can copy stuff across to.

2. If this fails, try it on the other computer.

3. If it still fails, then switch off any firewalls on both computers and try again on both computers.
Remember to switch the firewalls back on again after you’ve finished.

4. If there is an icon for the other computer, but no shared folder to copy stuff to, then you need to share a folder.
Open "My Computer" again.
Right-click on the C drive and choose "Sharing and security", click on the "New Share" button, enter a name (doesn’t matter what) and say OK.
Repeat for the other computer. Then try steps 1 and 2 again.
Hopefully the C drive is now shared and you can copy stuff across.
Remember to remove the shares again when you’re finished.

5. If you still can’t see either computer then press "start" (bottome left), then choose "Run…", then type CMD and press OK.
You should get a black box you can type into.
Type ipconfig and press Return.
You should get a line saying IP address and four numbers separated by dots (e.g. 10.15.20.25)
Write these down.
Go to the other computer, open Explorer, and in the address line type \\ followed by the IP address, followed by \c$
e.g. \\10.15.20.25\c$
Hopefully you should now be able to see the C drive of the other computer and copy files across.

6. If this fails, repeat using the computers the other way round.

I’m thinking about getting an HP Elitebook with 24 hours of battery. Is there any other cool looking laptops with a battery life over 10 hours with a disk reader?

when it comes to laptops and ESPECIALLY LAPTOPS you should NOT be concerned about how it looks at all. the first thing that should come to mind is the Specs. ive seen friends get so excited about how theyre laptop looks and then a year later they need to buy a new one. thats what HP and Dell try to do. make everyone think theyre laptops are the best because they look cool or you can customize the look of the cover. here is a good laptop that will look pretty cool anyways and have alot of battery life there is 17 inch and 14 inch if your looking for small or big laptops. never mind im sorry i looks like dell discontinued theyre inpiron series i cant fint it/ but if you happen to see it in a store its called the inspiron 15. i think with a 9 Cell battery it can last up to 9.3 hours.

Complement your home decor or impress from the road with the cool colors and smooth lines of the VAIO N Series Notebook. In addition to its Intel processor and elegant form factor, this easy-to-use notebook features a suite of multimedia software and a stunning 15.4″ widescreen LCD display with XBRITE-ECO technology.
