CentOS 5 Networking :: How To Create Wireless Network From Command Line With Hidden ESSID
Feb 27, 2011
I have a CentOS 5.5 server running currently with a Netgear gigabit ethernet card and for wifi I have a wi-fi card with the chipset: RT2860.Now I have gotten the ethernet card and wi-fi card working but my main question is: How do you bridge the connection between the ethernet card and the wi-fi card to create a wireless network with a hidden ESSID if possible and WPA encryption? (So the server basically acts as a wireless router as well as doing all the other stuff I need to do on it).

Running BT5, aircrack-ng v. 1.1, Alfa AWUS036NH.
My curiosity has been aroused by a local AP that is not transmitting an ESSID. It also is neither transmitting beacon frames nor data.
The channel shows a negative one, as does the power. Facts:
1. I know this AP is nearby because, before they hid the ESSID, the power output was fairly high.
2. Airodump-ng shows -1 channel, -1 power, and a hidden ESSID, although the BSSID is visible. Neither the channel nor the encryption scheme are being transmitted.
3. Neither beacons nor data are being sent. I can determine the correct name of the ESSID from the probe field in airodump-ng
but that is all.
4. All attempts in aireplay-ng to dissociate the client fail with the message that "No such BSSID" is found!?
5. Kismet, on the other hand, does not even see the AP.
6. Loading the .cap file in Wireshark reveals no information about those packets for which the source, or dest, is the AP.

I am fairly familiar with Linux but had never ventured into Wlan settings / options / too much. I have compatible card (aetheros) and when running - iwlist wlan0 scanning - I get plenty networks showing up - meaning the card works. When I installed distro which is last night (before I ran update), I had that little bars menu at the top of the screen that showed available networks once clicked upon. Since I like to modify and make my settings better - I removed that little AT&T like bar, and now rebooted after update to find that I can not see available networks unless I use iwliset wlan0 scanning.... .#$*&)@&#(&%# - need I say more.
Two questions - how do you connect to the wireless network via command line? What is that vertical bars GUI tool called so I can find it and run it again? Is there (for the love of god) alternative to system-config-network GUI managment tool for wlan?

I am trying to do a command line installation.Finished the installation and my wireless card wasnt working.Did a "sudo ifconfig wlan0 up" and got it working.But for some reason wireless-tools is not installed thus I dont have iwconfig, iwlist, etc.The wireless works and connects fine off a liveUSB.So I am going to give info from this liveUSB run and maybe someone can suggest how I can set the right settings on the Command Line Installation I presume in the etc/network/interfaces.

I am having a little trouble connecting to my wireless network. Running Fedora 10 32 bit.I'm trying to connect to a hidden wireless network. I updated the firmware for my driver but apparantly the driver is still not working. Broadcom has a driver from their website for Linux 32 bit systems. Should I attempt to install it? I read a post where the driver is built into the system kernel. If so I would need to blacklist the one of the drivers. Correct?
[justin@justin ~]$ iwlist scan
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
wmaster0 Interface doesn't support scanning.

After installing Fedora 15 on my notebook, I found that the one thing that I am unable to do is connect to a hidden encrypted wireless network automatically. I've seen plenty of people inquiring about this online but have found no solution. I can set up whatever I want to in my settings (using the old gnome2 interface setup, the gnome3 interface setup leaves the wireless options unconfigurable for some reason so I can't do anything with the "Network Name" dropdown)
All of my settings have been set up using the network manager from gnome2, but that doesn't seem to translate to my gnome3 desktop. So, is there any way to get the wireless to connect automatically on startup? I know my wireless card is working when I start my computer because it shows some of the networks in the area and I can connect to a few of the unprotected networks. This is the only problem I have with gnome3.
EDIT: from dmesg, I find the following: [485.63] ADDRCONF(NETDEV_UP): wlan0: link is not ready
EDIT #2: Going into the network settings just to play around with it, I discovered that the network name dropdown box appears to be grayed out, but now it works when I click it (didn't the first time) -- this allowed me to connect to my hidden wireless network. Still however, it does not connect automatically (system default is the hidden wireless network) and I still have the DNS problem

When I click on the 'connect to hidden wireless network' I get a pop up window. All boxes are selectable with 'new' as the connection. If I click on that drop down and select my ESSID, all the boxes, including the 'connect' box are greyed out. If I enter new network name and the security I can get a connection. If I put down my original ESSID down as the new network name, it works, but if I then look at network preferences, I have two wireless connections with the same name.

My network has SSID broadcast turned off, it took me several attempts before the crappy ubuntu network manager figured out that I want to connect to that network automatically.
Yesterday my laptop ran out of battery and entered on hibernation. Now, the crappy network manager can not connect to the network anymore. I tried everything. I restarted, I removed the connection from the list. But after asking to connect to the network, and enter the SSID and the WEP key, it simply won't connect.
The worst part is when I tried to load a pre-defined configuration using "Edit Connections", It displays the connection name, but the "Connect" button is disable.
Is there any way to connect to this hidden network? Or it is not supported.

The wireless network on my laptop is configured with a static IP. (not using nm). When I take the laptop out of the range of my wireless router the essid is becoming off/any therefore when I'm back in range the connection is not reestablished and to re-enable the connection I gotta do "iwconfig wlan0 essid <essid name>" otherwise there is no connection. Make sure that essid stays configured unless I manually want to change it?

I run Ubuntu, and it has a nice GUI widget thing that connects me to my home wireless network when I boot. I don't have a problem with that. But suppose I don't start X, and boot to a recovery console for some reason, like I did recently when my graphics were broken after installing Karmic. In that case, my computer won't be connected to the wireless network until I log into X normally. So I can't apt-get anything or anything. It's very annoying. And I don't know how to connect to my wireless network.
I know my wireless network SSID, and I know my WEP key or WPA passphrase. How can I log onto the network with commandline tools? Is there some basic program that I can just run "networkmanager <myssid> <mywepkey>"? I looked at the iwconfig man page and I honestly couldn't figure out how to simply connect to my network. Once I figure out how to connect to the network with command-line tools, where can I put an "autoconnect" script so that it will connect during startup, like it should anyway?
What I don't understand is, why the Ubuntu network manager nm-applet, doesn't just work as a front-end for more basic networking stuff. I don't see any reason why it should require you to start X before working; it could be a daemon that runs at startup, and there could be a config-file somewhere, but it doesn't even start running until I log onto gnome.

I use xterm and my kernel launches framebuffer before X windows.I reckon this is what's reponsible for hiding my all-too frequent typing mistakes.I'm a terrible typist, especially when in a hurry, but obviously you see your mistake and you correct it.owever if the terminal actually hides your mistakes, well you can have a frustrating few seconds. This sometimes happens to me and I think it's due to my Spanish keyboard and all the special characters that I can mishit. When I go to correct them (at least visually) the command fails and bash reports back (say, the filename) with an extra character (often a question mark).This all happens quickly and easily corrected but it's very annoying becuase of the way it hides these mistakes from your eyes

I'm trying to connect to a wifi network where it hijacks all requests and redirects you to a page where you have to agree to a terms of use before it lets you connect to the actual outside world. This is a pretty common practice, and usually doesn't pose much of a problem. However, I've got a computer running Ubuntu 9.10 server with no windowing system. How can I use the command line to agree to the terms of use? I don't have internet access on the computer to download packages via apt-get or anything like that. Sure, I can think of any number of workarounds, but I suspect there's an easy way to use wget or curl or something.
Basically, I need a command line solution for sending an HTTP POST request essentially clicking on a button. For future reference, it'd be helpful to know how to send a POST request with, say, a username and password if I ever find myself in that situation in another hotel or airport.

I'm thrilled using wicd to connect to wireless networks. But when I suspend my laptop using the special keys, I just want to disconnect from wireless without having to use any kind of GUI or curses user interface. It says in the documentation that wicd works by sending DBUS messages, so presumably it's possible to write a command that talks to the daemon directly.But I can't figure out how.Does anybody know by means of what shell command I can tell the wicd daemon to disconnect me from my wireless network?

The university I go to uses a WPA2 wireless network that requires a netID and password to connect too. I installed wicd but I can't seem to connect to this network, is there a way to add this functionality to wicd, and if so, how do I do that (links to a how-to or guide would be nice, I've yet to find one).
Also, I spend most of my time on campus in the command line, so I'd like to know if there is a way to use command line utilities to connect to this network (again, a guide or how-to would be nice)
I can get online through my fedora live USB just fine (w/ network manager) but I'd rather get on directly from slackware.

Next week we will get a new Server for rent with a preinstalled Debian. If we download the Networkinstaller and put it in Grub, it is possible to set some settings with a script or commandline? We need SSH and the Network haves to run. So we have to set up the Networkadress , Gateway and Netmasq. So if the Networkinstaller is booting that we get direcly access with SSH to install CentOS. It is possible?

Kernel: 2.6.27.15-170.2.24.fc10.i686
WLAN: Broadcom BCM4311
Problem: I run WPA2 Personal encryption on all my wireless devices. At work we use Cisco WAPs and I can connect flawlessly, simply by entering the password. At home I use Apple's Timemachine, which is basically an Airport Extreme A/B/G/N router.
I go to Network Manager and choose "Connect to Hidden Wireless Network". I enter in the SSID of my home wireless, choose WPA2 Personal, and enter in the password. After ~1 minute Network Manager spits back a window requesting the WEP key.... But I'm not running WEP. This is extremely frustrating. I delete the network and try again... same behaviour. My assumption is that this may be isolated to Airport Extreme network devices but I'd really love to find a fix. Just FYI: I have a MacBook Pro and a system running Vista that connect without a hitch.

I'm new here but have been using different distros for a couple of years. I ran into this problem like a year ago for the first time and I really would like to solve this ( with your help now). I've already used hours trying to figure this out and seeked solutions online. So first things first:
- I want to connect to a wireless access point from CLI (for many different reasons)
- I'm using Fedora 13 with KDE and Gnome some specs:
Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) Kernel driver in use: iwl3945 Kernel modules: iwl3945

I have setup my wireless card via ndiswrapper and I can see that if I perform an iwconfig that the card is wlan0. I have attempted to connect with the router but I can't get any connection.I know the password is: ########## (10 digits long) but for the life of me I can't get it to work via command line.

I want to run OpenBox on a netbook. For those of you not familiar, it is a very simple window manager, where I can launch a terminal with a mouse click, and I can start the few apps that I need from the command line. Basically, I am trading eye candy and easy access to a lot of stuff I don't need for a more responsive GUI.
My question is...what package should I install, and what corresponding command line would be used to launch a tool to manage the wireless LAN connection?

Ive been struggling to configure a wireless interface on Fedora 9I need to configure wlan0 command line only with NO display managerIve tried setting up /etc/sysconfig/network-scripts/ifcfg-wlan0 with the right information, doing dhcpbut no ip is retrieved. Checking the dhcp server logs on the DHCP server - no request is received.The link light on the wireless nic is not on either. iwconfig shows it has an Access point associated and an ESSID but im not getting back any IP.There seems to be very little documenta on how to set up wireless nics command line only on Fedora

Without Gdm (The GUI Desktop running), or an Internet connection, how does One get pppd or wvdial to connect to a wireless broadband modem?I'm SURE this can be done with any modern Distro without additional downloads...but seem to be missing some crucial step...? I've been trying things like: (scrips for pppd and chat and ln {links} ttyACM0 to /dev/modem?) the modem is definitely on ttyACM0.
ln -sf /dev/ttyACM0 /dev/modem
/etc/ppp/chat-script
#!/bin/sh

The title about says it! I have a major problem on my laptop after installing updates. Some of my icons in the top panel are broken. So as a first step I need to reinstall a few things. The first step is to start the wireless connection from the terminal. So would someone please tell what the command is?

I've been familiarizing myself with the command line and am attempting to connect to a wireless network but am getting stuck at the point wherein I need to put in a password.When I run iwconfig I see my card is wlan0.I definitely know my password as I can connect using a GUI. The encryption method for my network is WPA2.Could someone tell me how I could connect to a WPA2 secured network via a command line, and/or where I went wrong with what I've been trying?

I wanted to run a little media server in my house, shared with my laptop only, so I could free up space on my laptop drive. I took one of my Linux boxes out of my render farm and loaded up a minimal install, command line only of Ubuntu Lucid from the mini ISO (32 bit). I had to plug in a lan cable to install, but I wanted to move my box back out to the "farm" that doesn't have wired access to my intranet.
After much research, trial and error, this is what worked for me. My wireless card uses an Atheros AR5001X+ chip, and it works with the desktop cd out of the box. I found the "just works" desktop install uses the ath5k driver that is now included in Lucid, but I'm not using a desktop or window manager. I haven't tried this on server version, if you do, let others know what you had to install to get it to work.
The things I do tell you about, I instruct you as if you are a newbie, however I have left out some things that users should know or be able to lookup easily, like if you want a static address instead of using dhcp. You may not need all of the steps or you may have to do more research and troubleshooting.
Find your wireless card (you may need to lookup what to do if it is not recognized at all)List all pci devices, only show network devices (-v verbose, -vv very verbose): >>lspci -vv | grep Network List all hardware (| less lets you pause at each page - arrow keys, page down/up to navigate, q to quit) >>lshw | less

I frequently ssh into machines to do work. In some cases, the machine is headless so there is no option to log in.Under Debian and on older versions of Ubuntu I would pull out the avahi and network-manager packages and manually configure the interfaces file to my liking and be done with it.However, I would now like to learn how to work within avahi/network manager. So, is there a doc somewhere explaining how to work with modern Ubuntu networking at the command-line level? Ie: Setting up a wireless connection, setting static/dynamic IPs, etc?
