Ubuntu Networking :: Make Computer Invisible To Other Clients On A Wireless?
Dec 26, 2010
I want to make my computer invisible or hidden to the other computers connected to the same wireless network. In other words, I want to turn off network visibility or network mapping. I think this amounts to the ability to turn on and off the Windows Link-Layer Topology Discovery (LLTD) Responder. [URL]... On windows, I believe this would be comparable to setting the wireless network as Public instead of Home. I like to share files using Ubuntu when I am connected to my Home router, but I don't want to be discoverable or visible to clients on a public wifi network.
I have already created a shared folder on my desktop which installed some sort of networking components to interact with Windows, but I don't want the public wifi network to see this folder, or my computer name at all. I want to be invisible to other clients on the same network. Right now I am visible and can see other clients connected to this public wifi router.
(In case some ask: I do not want to disable SSID broadcasting on the router as it is a public wifi router that I do not have access to.) Can anyone explain how to do this (preferably with a GUI method so I can reverse the steps when I connect to my Home network)?

I go up to the panel and click on the wifi manager, create a new network and name it "loganspc" with no authentication since previously created networks didnt work with those settings. Now before, I used this in conjunction with my eth0 connection so i could give my ipod internet. then i got a wireless router to do that. its exhibiting the exact same problem. Both the router and my laptop's network are invisible. I create it and then i cant connect to it with my ipod. I do a wifi scan (with an app, its jailbroken) and it doesnt find it still. nor does it find the routers network.

I've just loaded Fedora 13 - my 1st Linus system - on my laptop. It went smooth and connected to the net via 'eth0'. But my wireless - an EVO610c Multiport W200 lan card - is invisible to Fedora. A couple of data points are:
[root@EVO ~]# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:02:A53:BE:ED
inet addr:192.168.0.12 Bcast:192.168.0.255 Mask:255.255.255.0

I have the NetworkManager applet 0.8.1 (2 pc screens) but don't see the "Network' icon under System->Administration I've read that should exist. I have placed the latest 'Windows' networking file from HP (sp2956.exe) into my download directory. What must I do to 'discover' my wireless card? I suspect the use of "ndiswrapper" and have imported it into Fedora. All updates have been done via 'yum'.

That is, the thin clients will have to get their OS image via TFTP, and their IP address via DHCP on a *wireless card* - is this possible?What spec should I ask for/search for when buying the WiFi card?

I've got a NAS running and I'd like to somehow make some of the folders and files invisible to certain users only. For example, if I 'ls' a directory, I want to see files 'a', 'b', and 'c'. But if another user does 'ls' in the same directory, I only want them to be able to see 'a' listed.I know I can use 'chmod +700' to make certain files not able to be read/written, but the filename would still appear in a 'ls'.I know I can put certain files inside of a '.hidden' file in the folder, but then it would be hiEdit : I'd also like to mention that the users that connect to the NAS could be coming from Windows or Mac operating systems. So hopefully the solution would work for users from those systems also..

To hide the user input to be displayed on screen, use the terminal line setting command stty -echo, whatever the user enters after this command will not be displayed in the screen. to make the input characters get displayed on the screen use stty echo.

I have a Dell Studio 1558 with a Broadcom wireless adapter. It's a brilliant piece of hardware and love everything about it except some of it's overheating problems. When I first bought it with Windows 7 pre-installed, it had an application installed on it called PeerNet, which creates a wireless network for other computers (and wifi-enabled phones) to connect to it. Simultaneously, you could also share your internet connection with these users. The internet connection could be either wired or wireless.
My question is, how do I go about finding the same functionality on Ubuntu since I know my hardware is capable of it. (I believe in Windows 7, it creates a virtual adapter that it uses) I know there are ways to share a WIRED internet connections with some help with the terminal, but I haven't found a way to share a WIRELESS internet connection. The network manager allows you to create a wireless network but I'm unable to connect to another wireless network at the same time.
The reason I mentioned mobile phones is because my mobile (Android 2.2) is unable to find a wireless network created by the network manager, but another laptop is (without internet access that is). I've noticed that mobile devices and iPod's aren't able to find ad-hoc networks on Windows PCs as well.
I hope someone out there will be able to find a solution for me (and surely others as well!) Maybe the final release of 11.04 will help out later if nothing turns up now.

I need straight forward directions on how to do this. I installed samba on ubuntu and I shared a number of ubuntu files. No luck.Xp can't see ubuntu and the reverse is also true. My searches just end up off on some tangents. Example, researching samba - I get the entire manual on samba - can't find the specifics I need within that document.

I have an Asus Eee S101 netbook running UNE 10.10. When I have the netbook on, I have no problems connecting to my WPA encrypted wireless network being broadcast by a Buffalo router running DD-WRT. When I turn on my desktop computer in the other room (running Windows Vista) which also uses the same wireless network, the netbook disconnects. Then it will take a few minutes to reconnect. Periodically it will do this until the other computer is powered down. I don't know if this is an OS issue or the hardware, but is there any sort of troubleshooting I could do to look into this? It seems like the desktop is somehow interfering with the netbook's connection, booting it offline.

Was wondering if anyone had a idea on how to install this wireless adapter onto a computer thats running Ubuntu. I don't have access to a direct connection so that won't work. So I need a way that I could install it without internet, I do have access to another computer that i could get files off of if needed.

I am using an HP dv6 series laptop. The wireless works fine in Ubuntu 9.10 (must install the Broadcom STA wireless driver). When I try to use Kubuntu 9.10 my computer crashes when I try to install the driver. Is there any particular reason why it works in one and not the other?

I have a Belkin Wireless G F5D7230-4. I was attempting to configure a wireless card on another computer on my network when it froze during the reboot phase after making settings adjustments. The wired connection is fine, except on that computer that I was making the adjustments from. It won't connect at all. I plugged a friends netbook into the same wired line and it connected. Also there is no wireless signal on any laptops. Mac, Win Linux, don't matter. I tried all the various methods of resetting to default but still when I try to access the router's config page @ http://192.168.2.1 I get the error Code: The server at 192.168.2.1 is taking too long to respond.

I'm trying to make my wireless router always give me the same ip address every boot (192.168.1.100). I do not have a static ip address from my isp.
Everything I've tried from online help has made my internet break and I'm not even sure what exactly I should be searching for on google.
Ultimately, I'm trying to get my wireless router to forward ftp requests to my computer which shares the network with an xp machine. I think this is the way to go about it.

The first two times I entered the wireless key on the prompt that appeared shortly after login, the computer froze completely. ctr-alt-f1 ctr-alt-backspace did nothing. The third time, I closed the first prompt and after 10 minutes I tried connecting again. It didn't freeze, at first. The internet worked. It took about 10 minutes later for it to freeze. Now, whenever I boot up, it freezes a few seconds after login. I can boot recovery mode, but I don't know what to do from there. Heres some info I got from the recovery mode:
Computer Brand: Sony PCV RX850
Ubuntu 10.4 32 bit 2.6.32-21-generic i686
Realtec 8185L chipset
iwconfig

Since I upgraded to Lucid, I am dealing with serious instabilities related to my wireless card. What happens is that when there is a lot of wireless activity the computer freezes. It is a complete freeze, the mouse stops moving, if something was coming out of the speakers it keeps echoing, and the only solution is to turn off the computer. The bug seems to coincide with the one listed in here

My wireless card is Intersil ISL3890/ISL3886. My whole computer is an HP z555. I'm thinking that is should be a bug in the wireless adapter driver, which is p54pci. The only solution I can think of is to blacklist it and set up ndiswrapper. I am not very comfortable with this solution since a native linux driver should be better than ndiswrapper.

I am in a situation at the moment which means I am going to be without an ISp for a week or two, and I can't survive that long without the intenet!!! What's more, I have 8 computers that need to connect, though not necessarily at the same time, but certainly more than one at a time. Anyway, I came up with an idea to buy a Mobile Broadband Dongle, and then share the connection via my PC. Problem is, I don't know how I would go about setting my PC to be a Wireless Access Point/makeshift Wireless Router, and sharing the connection.

I am trying to connect to an apple computer wirelessly to get access to the internet.. If no encryption is used on the network (gateway?) set up by the apple computer I can connect just fine and browse the internet.
-If a WEP encryption is introduced I cannot seem to connect... even though the WEP keys are identical.
-I have tried both WEP 128 passphrase and WEP 40/128 key... -Have tried the WEP passphrase being both just numbers in case that mattered.

Installed Ubuntu 10.04 on my Sony UX280p with Intel 4965 wireless. Ubuntu detects the card without issues (as far as I can tell). I can see all access points in my area and select my access point and pair with it. I get a DHCP address from the AP (if ifconfig is to be believed) and iwconfig shows the ESSID of my AP but I can't ping the AP or any other computer on the network, nor can I ping the sony from any other computer on my network. Last year I had installed 9.04 on this computer and wifi worked out of the box without any issues.

just switched from Windows Vista to Ubuntu 10.10 on my Toshiba laptop and I'm loving it, except for some wireless connection problems. About 70% of the time, my computer is unable to find any wireless signals whatsoever, despite being right next to the router. When it does find the signal it connects fine and runs great, but most of the time it doesn't show any signals at all. I can't find any pattern to when it does or doesn't find the signal. My result for the "sudo lshw -C network"

I first noticed the problem because my wireless internet will stop working. The usb stick has its LED constantly on but it fails to connect. I have tried some methods of restarting the networking, like "sudo restart network-manager", disabling and re-enabling the wireless and networking from the taskbar applet. I tried removing the module and restarting it. It might be a bigger problem because I'll find that things will randomly hand for awhile, like opening system monitor, or running terminal commands. They do eventually run but only after several minutes. A restart seems to get everything working again, but the problem comes back at random times. I am willing to solve this right now as I have time, just let me know what info you need and I will post it.
Update: Some more info I forgot to include. I am running Ubuntu 11.04. It just froze again, I tried logging in and out but the internet still wouldn't work and things were hanging, I couldn't get file manager open. I have even tried shutting down the computer and had it stall on the Ubuntu logo with the dots loading so I had to hard restart.....

I did a clean install of 10.04 on my Toshiba Satellite laptop, but I cannot make a wireless connection. The icon on the panel spins round and round, but that's it. After a few minutes I will get a message that the wireless network is disconnected. Any ideas?
