How To Automatically Detect New Network Card In CentOS 6 / RedHat
Sep 5, 2011
I'm using CentOS 6 in a virtual environment. When cloning a virtual version of CentOS, the old eth adapters are "removed" and replaced with new ones and net MAC addresses. However, the ifcfg-ethn files still exist. I am trying to figure out how to get CentOS to automatically rescan & recreate the network adapters / eth files, just like it did on install. url...
I know there is a quick way to do this in the GUI, but we are using a server so GUI does not apply in this case.
however Kudzu has been removed as of Centos 5 so I would rather avoid that. There is a procedure that Linux runs on initial install - what that is so I can manually trigger it?

I am running Windows 7 and I use a ZyXEL ZyAIR G-220 Wireless USB adapter for internet. I had a virus called something like Cloud AV 2012 so I used Malware Bytes to remove it and it worked just fine. However, now the internet does not seem to work (there's that yellow triangle with the exclamation point) and when I try to run diagnostics, the message "Windows could not automatically detect this network's proxy settings" comes up. So far, I've tried rebooting, disabling proxies in all of my browsers, and running scans, And I also cannot system restore, because apparently windows security was turned off and there are no restore points

I'm on windows 7 btw.When I diagnose the problem it says: Windows could not automatically detect this networks proxy settings I'm connected to the internet via cable on my laptop. Yes I'm using a router. The other computers connected to the router can connect to the internet but mine can't. It also says "unidentified network - no internet access" when I click on the computer icon in the bottom right corner of the screen. until I downloaded from a music site which gave me the virus I think. Now, I'm not certain if the virus is removed or not. I tried system restore point but it won't even let me restore my computer anymore for some reason, maybe because of the virus.

I'm using my old laptop now. On my regular laptop, my internet icon has the yellow triangle and when I trouble shoot it, the message says "Windows could not automatically detect this network's proxy settings".Recently I noticed my computer was heating faster (and hotter) than usual so I ran a search again and it said no threats were found. I have ran the search twice since then and still nothing. I was advised to use ccleaner,malwarebytes, and Super Anti-Spyware. It removed one other threat but the problem was still there. I then started using combofix, but I did not like the look of it so I stopped that scan. It seemed a little sketchy. As of this morning, I'm having the internet problem. My old laptop (the one I'm on now) and my girlfriend's laptop work fine. I connected it with the Ethernet cord and that didn't change anything. I have Windows 7. It's on a 2010 Samsung (I'm not very tech savvy so I'm not sure about all the other details).

The other day i was on my mums laptop (ASUS X5DIJ) at her house all working fine the battery died so i plugged it in and started it up again however the charger cant have been fully connected and once back in windows the battery died again on the next boot i noticed windows said it had found the system CMOS/real time clock and had installed drivers for it. checked the driver details it says no driver files are required just like it should ever since then it connects to the network but will not connect to the internet at her house or at mine through wireless and ethernet cable although all other computers work fine windows troubleshooter says "Windows could not automatically detect this networks proxy settings"
I've tried
resetting routers and laptop = no change
netsh winsock reset and netsh int ipv4 reset = no change
ipconfig /flushdns = no change
ipconfig /registerdns = no change
[code]....

I got DELL inspiron 1012 with built-in mini wireless card in windows 7 starter. The laptop could detect the card and I could connect to the internet until when I downgraded to windows XP service pack 3, and then it could not detect the card anymore. I downloaded all of the driver in DELL support site and installed them to the laptop but it sitll could not "see" the card. I checked in the Device Manager and did not see the folder "Network Adapter" at all.

In my company certain site have been blocked, they were using CCProxy to limit the accessDuring those times i would just choose automatically detect proxy settings and i would be able to get connection. But now they have done something advanced and Now i cant access internet without choosing the manual proxy, also no other applications(Like Torrents) gets internet connection. The Network icon shows a warning sign with a mouse hover text no internet access. But some of the seniors are getting complete access

Now my problem started happening after my desktop computer got unplugged. When I booted back up, I was unable to connect to my access point. Or find any of the other networks it can always see. I took my laptop and set up an ad hoc network and it came right up. The wireless access point has not been changed and it is perfectly fine. I've updated the drivers from Ralink, nothing. Uninstalled and rebooted, nothing. Checked the BIOS for any settings, nothing. Made sure the radio was turned on, nothing.

i have a strange connection problem. My wifi adapter which should be Dell wireless 1701 is not detecting my router automatically. Sometimes it takes one hour to detect it. Sometimes it detects it but connection fails. My router works fine with a tablet and another laptop. My N5110 is having a problem only with that device which was working fine for few days. It is able to detect neigbour's network and another router.

I'm having problems with a linux box we're using as a VPN/IPtables firewall. The setup is such that we're sitting this thing behind a basic Comcast cable modem will all the pass through options set. The outside facing interface is set to DHCP and grabs an IP address from Comcast. Inside interface is statically set with the same being said for the CIPE interface. The inside interface works until we plug up the outside. When we plug up the outside interface, all network traffic to the box effectively shuts down and the /var/log/messages is flooded with "neighbor table overflow" messages. Sometimes, this takes a few seconds to appear, and when that happens I can track some traffic hitting the far side of the tunnel, I.E. it works for a few fleeting seconds.

I have a laptop running Windows XP Service Pack 3. There is a CentOS 6.0 desktop next to it. The Windows XP laptop has a Wi-Fi card, and it has Internet access. The CentOS computer does not have a Wi-Fi card or Internet access.
I don't want to purchase a wireless NIC for the desktop. What are the steps I can do to get an Internet connection from my Windows XP laptop to the CentOS desktop?

I've just registered with NO-IP (free account), created a host, installed the client (in CentOS) and I want to see a website I'm running locally in that computer from another computer (via internet :). How do I access it?My host is "customtrack.no-ip.org "And in that unix box I've got a published website that I can access from any browser in the following URL: [URL]When I log in to from the browser from another computer I get the following error message:
Quote:The connection was reset- The connection to the server was reset while the page was loading.The site could be temporarily unavailable or too busy. Try again in a few moments.If you are unable to load any pages, check your computer's network connection.If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
How do I tell CentOS that I want to redirect that site I'm hosting locally [URL] to [URL]? I believe that's not done automatically. How do I configure the redirection?

I am having a problem in which when ever I check "Computer" later on in the day, one of the network drives is duplicating itself over and over using a different drive letter each time. By the end of the day if untouched I can have approx 20 of them!To give you more information about the scenario, the computer is on Windows 7 pro, it is on a domain in which the server is 2008 r2, there are 2 network drives in total (only one is duplicating), the only 2 changes I recall that may have caused it is box.net is running on the server syncing all content on the networks drives and a new printer has been added on the network.

I've been having a problem with my wireless network connection. Whenever I try and hit the Repair function,it will get stuck on Renewing your IP address for a moment, then change to: Windows could not finishing repairing the problem because the following action cannot be completed: Connecting to the wireless network. I have internet connection on this same computer.Another point to make is that when I click Repair and navigate to the Network Connections window, then hit F5 ( refresh the window ), the wireless connection will quickly refresh and connect normally without error.I won't have to open the Network Connections page and hit F5 anytime I need to repair the connection? Also, as of right now, it's still "Acquiring network address" even though I'm connecting and typing this message.

I used to have an old G5 tower running OS X 10.5 (Leopard) which I was using as a file server. In this tower I had a USB dock connected where I could plug in 2.5 inch drives from my archive and then access them over the network by connecting to the G5.
Last week I upgraded my "fileserver" and I am running OS X Mountain Lion Server on a regular Mac Pro tower. When I connect to my new fileserver via Finder I am only able to see the local hard drives but none of the external ones. I can add a share-point for the external drives but that is not very practical since I am always connecting different drives from the archive.
So what I would like to have is that when I plug in an external drive to my file server it shows up in the network shares without me having to create a share-point for every different drive I connect.

So I just finished building my new PC. Installed windows 7. Plugged in wireless network adapter in USB port. It detects it and I'm able to connect to the internet. I download chrome and install it.
I restart the computer. And now it shows I have no network adapters and I can't find it in device manager. Plugged it in again in, used different ports.. to no avail. I plugged the network adapter into another PC and it works.

I log onto other wireless networks the first time by inputting their passwords. My iphone then always automatically reconnects wirelessly to them without have to input the password again. The phone can be asleep for a few minutes or I can be gone for a month. The phone always automatically remembers & reconnects to these networks.However, it doesn't work that way with my d-link system @ home. Everytime the phone sleeps and I wake it up, the wireless connection is lost. There is no automatic reconnection. I have to input the password each time in order to re-establish the wireless link. My printer and laptop seem to stay connected. d-link settings I need to change in order to get my iphone to automatically connect all the time?

How do I fix my network so that my Windows 7 and XP computers automatically detect each other on the network. Right now, they cannot browse each other by computer name, instead I have to type their IP addresses (for example: \192.168.2.5) in the windows explorer address bar, and then I can browse to their shared folders. And under "Network" (in Windows Explorer) each computer only displays itself, and not the other (unless I have already typed in the other's IP address, in which case it displays the other computer as the IP address).

My Compaq laptop (Vista) was working just fine last night, connected to my home wireless network all right and all. Today morning my laptop couldn't detect my home wireless network at all, but it could still detect a bunch of other networks from the neighbours. My iPhone can detect my network with no problems, my desktop computer is wired up to the router, works fine too. It's a D-Link DIR-655. This has happened before but usually gets solved when I reboot (switching off and on) my router. I've tried that, tried restarting my computer too, no use. Haven't tried anything beyond that because I'm an idiot with computers.
