WiFi does not have such a range normally. In any case, you will need a number of bridges/repeaters. You can send from one repeater to another over a long distance using a Yagi-Uda directional antenna. I've used them in the past to bridge local WiFi transmitters over a distance of 100's of yards to over a kilometer. Bear in mind that you may well violate federal (FCC) power limits using this technology!

IPv6 Is this long;
00001111 11011000 00001111 10001000 11111101 11100100 11100101 10111011 10001100 01100010 11000011 11111111 11111110 00000000 10100101 10111100

Of course, we don't typically see the addresses in this format, but rather we see it as in the typical format below;

fd80:f88f:de4e:5bb8:c62c:3ff:fe00:a5bc

It is 128 bits in size.

IPv6 address has length of 128bits.
For example: 00001111 11011000 00001111 10001000 11111101 11100100 11100101 10111011 10001100 01100010 11000011 11111111 11111110 00000000 10100101 10111100. It is represented using the Hexadecimal code like fd80:f88f:de4e:5bb8:c62c:3ff:fe00:a5bc.

My guess is that drindran is simply trying to stuff his link in a response. there are others similar to this post by this user.

@sohel08,
What type of IP are you assigned with?Is it a Static or a Dynamic one?If it is a Static IP then you need to request your ISP for the change and if it is a dynamic one you can reset your modem(switch it OFF and ON)which will generate a new IP.You can check for the change in IP by using http://www.ip-details.com/ and confirm it.

Yes,Static IP is extra charged by the ISP.This is because they dedicate that Ip to a single user so that no one else shares that IP.Dynamic IP is profound to change.If you so necessarily need a constant Ip you can approach your ISP in regard of it.Once you get the Static IP you can reset your modem and confirm that it doesn't get changed using Ip-details.com

Ok, sorted it out.

Although SAMBA was running with the correct permissions, I hadn't adjusted the Linux folder permissions which take priority over those of SAMBA and therefore cancelled them out.

I was struggling to find a good place to put this one, should it go in the Linux forums, should it go in the Windows forums? Anyway, networking seemed like as good a place as any so here goes:

I'm currently setting up a SAMBA file server which I am planning to use for backups. The problem is, the moment I try and restrict access to a folder it locks me out completely, I shall post my smbd.conf file to show you what I mean:

[global]

    workgroup = WORKGROUP
    security = user

[PublicFiles]

    comment = Public File Shares
    path = /home/FileShares/Public
    browsable = yes
    guest ok = yes
    read only = no
    writeable = yes
    create mask = 0755

[Alexander]

    comment = File Shares for Alexander
    path = /home/FileShares/Alexander
    browsable = yes
    valid users = alexander
    guest ok = no
    read only = no
    writeable = yes
    create mask = 0755

I can connect to the PublicFiles share and view content in the folder, however if I try to connect to the share 'Alexander' it won't allow me and gives the error "Access Denied". The same thing happens if I try to modify or add a file to the PublicShares. I have setup a SAMBA user, and the password is correct however I don't know what I am doing wrong.

It is an Ubuntu 12.04 server, trying to connect to it with Windows 7

Any suggestions or help would be appreciated.

Thanks

Does the laptop with the issue work on any other Wifi AP? It could be hardware you know.

In simple terms, we are exchanging our views and this is due to the networking of computer nodes at very advanced and vast scale :)

You might need increasing the strength of wi-fi signals in the Modem console.

TCP/IP means Transmission control protocol/Internet Protocol. About the DNS issue, be more specific.

People that ask questions like this are usually doing it for homework from school or projects for university. I don't know about you but I have better things to spend my time on, like people that have problems that need help.

The scaling option is used internally by the protocol to decide how many bytes can be sent out on the wire at a time. Without scaling, you are confined by the size of the window field which is 16 bits. With only 16 bits you get 2^16 or 65535 bytes. For certain links (in LFNs) the bandwidth-dealy product (BDP) allows for a much larger amount of bytes to be in transit at any given time. If you use the scaling option, you can left shift the value of the window field to acheive much higher windows on such networks.

For example, if you have a BDP of 124,733 bytes then 65,535 bytes will only fill ~52% of that without scaling. However, setting the scaling to left-shift the window by 4 you have a theoretical window cap of 2^16 << 4 or 1,048,576 bytes which is more than capable of saturating the link described above.

Note that the scaling negotiation happens only once during connection handshake and is fixed for the remainder of the connection.

Ever heard of google???

If that line of thinking was adopted by these forums then there would be 0.00 discussions taking place here.

For example, and this is an overly simplified example, you want to know how to spell the word 'gnome'. You ask someone how to spell the word and they abruptly tell you to get a dictionary. So, you go and get a dictionary and because you didn't know that the word 'gnome' begins with a silent 'g' you spend a lot of time looking up all the words beginning with the letter 'n'. You simply wouldn't find your answer, would you?

Another good reason for asking questions in a forum setting is that you will be helped with an answer in context with your problem. For example, if a person says they have a projector with the model number ABC123 and wanted to know the best way to connect it to a Tablet with the model number ZYX321, then researching this via Google may be complicated for some people. But, in a discussion forum like this it would not take someone with some technical expecting to do a few quick checks on specs and then provide an answer or some options.

So, Mr. Rik from RCE, please check this link for more info:
