  • Internet Connectivity Indicicator on Unity

    - by Sathish
    How can I check whether my internet connection is active on Ubuntu. If I am connected to a wired or wi-fi network, the indicator applet shows that I'm connected. But there is now way to find out the internet is working or not. I have some problem in my internet connectivity and I frequently lose my connection. I found this link is useful Internet connectivity indicator applet But I don't know that where should I use this code! #!/bin/bash if ping -c 1 -W 2 google.com > /dev/null; then echo "Up" else echo "Down" fi

  • Fixing IP Renewal After Laptop Suspend

    - by Cerin
    I have a laptop running Ubuntu 10.04, and I've noticed that with some wifi networks, but not all, I'm unable to reconnect after coming out of suspension. I've tried both Network Manager and Wicd management daemons, and both get through validation, but get hung up on "Acquiring IP address...". The only solution I've found is to reboot the machine, after which it acquires an IP address very quickly. What's the underlying issue here? What would be a more efficient way to resolve the problem? EDIT: I've noticed that if I open Wicd and manually press "Connect", it fails to acquire an IP. However, if I do nothing and let it automatically try and connect, it acquires an IP and connects just fine...

  • Why has wireless disappeared after my 12.10 upgrade?

    - by Shay Guy
    I just upgraded to 12.10 on my Lenovo B570 laptop. NetworkManager isn't displaying a submenu for wireless connections at all, even though I downloaded the update through the wireless connection. This displeases me. Stuff I've tried includes: $ sudo modprobe wl FATAL: Module wl not found. $ sudo lspci -nn | grep "BCM" 02:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01) $ rfkill list all 0: ideapad_wlan: Wireless LAN Soft blocked: no Hard blocked: no ETA: linux-headers-generic is already the newest version, and what I get when reinstalling bcmwl-kernel-source includes the following, near the end. DKMS: install completed.

  • mobile broadband quick connect..how to?

    - by Ubuntuser
    Hello all, I have a Reliance broadband + mobile broadband connection. It connects fine, but the only problem is it takes more than 2 -3 mins to get the connection started. If I plug in the USB datacard, the network manager applet dothes not show up the mobile broadband connection immediately. It takes a good 2-3 mins to detect the connection before I can select Reliance connection from the dropdown list. Is there any way of getting a shortcut of that connection on the desktop or on the panel? Thanks, Sayantan

  • Is it possible to auto-mount sshfs

    - by Mark D
    Is it possible to auto-mount a remote FS using sshfs upon instantiating a proper VPN connection? Allow me to explain the scenario, I'm working remotely, to do that it helps if I can mount my home dir from a server in the office. To do that I need to vpn in. So within network manager I select the relevant VPN and connect. It connects but now I have to drop to the command line and mount my home dir on several machines. If I forget to do one machine my local dev environment isn't as efficient. I suppose I could write a quick bash script to do this but I'd rather get it running automatically when I connect.

  • What does a media server need?

    - by DeaDSouL
    I want to buy a new PC to be used as a media server that streams HD movies, music to any wireless device on my network (laptop, desktop, TV, etc.). I was wondering about the PC hardware's specifications that I need to have so that it can work just fine? (It will be wireless) Is there any tutorial showing how it could be done? And the security - how can I secure it? As well as I need it to to host my emails. I mean I have many emails. And sometimes I'm using desktop, sometimes laptop.. so is it possible to make the server store a copy of my emails, attachments, all sent items (whether they were from desktop or laptop)?

  • Realtek 8188ce stops working after 2minutes

    - by Max M
    I am using ubuntu 12.10 on an hp dm4-2191us via wubi with the Realtek 8188ce wifi adapter. Everything works very well with the exception of the wifi. I have used wicd and it didn't worked at all so i went back to Network Manager with variable success. It works for 30 min - 2 min before i have to reconnect to get it to work again. I would really like to use Ubuntu (it is a better platform in my opinion) but no wifi could really be a deal breaker.

  • How to setup VPN as Proxy

    - by Nicolas Nox
    I have an PerfectPrivacy VPN connected via the OpenVPN-Network-Manger-Plugin (Ubuntu 12.04.1) and I want to assign a system wide proxy over that VPN. I have tried proxydriver that should do that automatically, but it works partially. The browser says that I have the IP of the VPN, but when I tried to send an eMail over SMTP (Port 25), I can´t connect to the mail server. In our company the smtp server port is closed, but that should be not a problem, when I do that over a VPN, shouldn´t it? greetings

  • Internet connection crashes while wifi / lan stay connected

    - by pirad
    I am connected to a router by wifi or lan. But every few moments (sometimes seconds, sometimes half an hour) my connection to the internet breaks down. So in one moment I can surf with my firefox and have ping times of 20 ms (wifi) to the google server. And in the next moment I can't open any pages in any browser and the ping shows no new messages first and then "Destination Host Unreachable". This is especially odd as another computer or my smart phone stays connected at the same time to the same network and seems to notice nothing. So I have a problem independend of wifi or lan drivers but with something else. Where should I look for logs that could tell me more information? I can't find some in syslog. Just if I reconnect to the router (wich works for another few moments) there are a lot of informations. But everythin is okay then.

  • A peculiar issue with nm-applet

    - by montreux
    There is a somewhat strange error that I've noticed with my gnome sessions. It's not a problem that causes a lot of trouble, but at times it becomes annoying. Anyway, here it is: when I fire up gnome-session-fallback (which is the main one I use), the network applet doesn't run with root permission. Here is what it looks like http://i.imgur.com/8kc7Vrd.jpg . On the other hand, here is what the regular gnome session looks like http://i.imgur.com/wfkkE3E.jpg . From the regular session I can easy edit and add networks, but from fallback session I cannot add/edit anything, or turn off/on the wireless or networking. Any ideas?

  • Connecting with a BSNL Broadband Internet

    - by user10026
    I am not able to connect my broadband connection with ubuntu and it doesnt work. The connection works fine when I use Windows7 but when i use ubuntu I am not able to access the internet. I followed various steps mentioned in various sites and still could not find a solution. I have installed ubuntu 8.04 in my system. The interface eth0 is not at all detected and when i use the menu system-administrator-network I am not getting an option for wired connection. Just the Wireless connection and Point to Point connection tabs are available.. It's really urgent.. I'll be very happy if u guys can propose to me a working solution to deal with this problem..

  • HTG Explains: What’s the Difference Between the Windows 7 HomeGroups and XP-style Networking?

    - by Jason Fitzpatrick
    Windows 7 rocks a new method of file and print sharing that’s a departure from the frustrating file and print sharing found in earlier versions of Windows. What is it and how can you benefit from it? Read on as we explain. HomeGroups are a new edition to the Windows ecosystem as of Windows 7. They’re intended to (and succeed at) greatly reducing the frustration experienced by users who want to easily share files between computers as well as share printers with the entire network.

  • configuring two network interfaces in ubuntu 10.04.1

    - by Bill Smith
    I have got two NICs configured on a VM - each is tied to a specific network, one is a DMZ, the other is an internal network. I want MySQL to listen on the internal network only and Apache on the DMZ listening for HTTP and HTTPS. But as soon as I add the second interface I run into trouble. I can hit HTTP on either interface, but can not hit 3306 on the internal network for MySQL. Here's the config... could someone sanity check this please? auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 10.153.24.230 netmask 255.255.255.240 network 10.153.24.224 broadcast 10.153.24.239 dns-nameservers 8.8.8.8 auto eth1 iface eth1 inet static address 10.153.24.195 netmask 255.255.255.224 gateway 10.153.24.193 broadcast 10.153.23.223

  • How to set the preffered network interface in linx

    - by Mike Cooper
    I have my network set up like this. http://docs.google.com/Doc?docid=0AZ1YxuLE4djaZGhqN2s1NmRfMjhjNjc0Ym1meg&hl=en In words: I have a machine (Calcium, running Arch Linux) that has two network interfaces. eth0 is hoooked up to a router, and is gigabit. Eth1 is hooked up directly to the university network over 10Megabit. The router's uplink is hooked up to the university network as well, and it is also 10Megabit. Currently (I believe) all traffic on Calcium is going through eth0, through the router, regardless of whether it is internal or external. (How can I confirm this?) Ideally, traffic that is destined for the internal network (192.168.10.0/24) would travel over eth0 to the router, and wherever it is going. ALL other traffic should go over eth1. I suspect that this behavior could be acheived with IP tables? I don't really know where to start looking to learn that though, so any links would be appreciated.

  • Mac OS X: network disabled because security breach

    - by fireeyedboy
    Dear all, I just recieved a message on my Mac OS X system telling me (loosely translated from Dutch): "The network has been temporarily disabled because the network's security was breached." (It's a wireless WPA2-PSK secured network BTW) I looked in the logs of my router (a Zyxel P-2602HW-D1A) only to see a few (outbound) "syn flood TCP ATTACK" logs, but those were from like a week ago, other than that nothing. What tools on Mac OS X do I have to analyse this security breach occurence? Are there some security logs on Mac OS X that I can inspect? What other measurements should I take? And how serious should I take this warning from Mac OS X? System: Macbook Pro Intel Core 2 Duo 2.2 Ghz OS: Mac OS X 10.5.8 Network: wireless WPA2-PSK Relevant software: Parallels Desktop with Windows XP (was open, but stopped at the time) Other systems on my network: Windows XP SP3 desktop (was running at the time) If you need any more info, don't hestitate to ask. Thanks in advance.

  • Docking Station Disabling/Enabling Network Connection

    - by bryan_cook
    Whenever I dock my laptop onto my docking station, Windows disables my Wireless Network Connection and enables my Wired Network Connection. Whenever I undock my laptop, Windows disables my Wired Network Connection and enables my Wireless Network Connection. Is there a way to disable this feature? After Windows performs the automatic disabling/enabling, I run into errors when I try to disable the now-enabled connection, specifically "It is not possible to disable the connection at this time. This connection may be using one or more protocols that do not support Plug-and-Play, or it may have been initiated by another user or the system account." I'm assuming the latter portion of the error is true ... my network connections are being enabled/disabled under a system account. Regardless, I'd just like to disable the feature altogether. For reference, I'm working with Windows XP Professional on a Dell Latitude D630. Thanks in advance!

  • Cannot remove wireless network profile even though admin account is used

    - by David Karlsson
    On my windows computer which is connected to a company domain. I have problems with the wireless networking. First of all the computer fails to connect. Second of all I cannot remove the network from the list of wireless profiles. The properties window simply claims that "This network is administered by the Administartor Account". I am currently logged in as the local administrator. I have also tried creating a new admin account and still get the same problem when trying to remove the network. My computer has only the microsoft security essentials antivirus and some VMWare+virtual box connections that I can figure might interfere, but disabling realtime protection has not helped me on this. I also cannot delete the virtual network adapters from the control panel / network adapters...

  • How to install Windows 7 From Network?

    - by George
    Hello SuperUser My question is that is it possible to install Windows 7 (Current RTM Version) on a computer without using removable media like DVD or USB. First thing that comes to my mind is network but i dont have experience of doing Fresh Install of Windows 7 via Network. How to install Windows 7 via network without any removable media? P.S. I know some may think that doing so, is just a waste of time and it's easier to do it with removable media, but in current situation the target PC neather has CD/DVD Drive nor supports booting from USB. And in addition to that, Target computer is connected to Network via Wireless Network (Dunno if it will make any problem with installation).

  • Network connectivity logs on OSX

    - by Stephen
    I'm trying to determine whether or not Macs store a log of network connectivity. Specifically, I'm trying to find out if one of my machines (Mac Tower, OSX 10.7.4, 2-2.26 GHz, 16 GB DDR3) lost connection to pinpoint an issue. This machine is on an external network where and the IT staff is not very helpful, so I'm trying to ensure that there were network issues rather than some other local issue on that particular machine. Can you pull network logs thru Console that show when a network connection was established and was disconnected?

  • windows 7 wireless knocks off other computers on the network

    - by Sean
    I am trying to fix a wireless network issue. When a new windows 7 machine (we have 2 in the house) we have problems with any other windows xp machines connecting to the wireless network. I am using a linksys WRT110 running Firmware Version: 1.0.04 (which is not the latest firmware its Ver.1.0.07 but the router would not use the bin update file). I have tried a ton of variations in setting for the wireless network, changed the channel, the security level (none, wep wpa, wpa2), network type (g,bg mixed). I have also read some stuff about homegroup settings for windows 7 but have not seen any differences that make a difference. Basically windows 7 does not like to connect to our network but when I manage to get it to work the windows xp pro machines get kicked off. The windows xp pro machines are a few years old but both windows 7 machines are less than 6 months old.

  • Unable to connect to network

    - by user33750
    Hey guys, I have a question. I have been having problems connecting a new netbook to my network at home. I have an Asus Eeepc 100HAB. I have tried to run a repair on the connection, uninstalled and re-installed the network card, made sure all of the drivers are up-to-date as well. Two caveats: I have a laptop that I recently switched to a wired connection because it wasn't connecting to the network as well, and the netbook connects to an unsecured network i found just fine, only having a problem getting into my home network. Passwords are correct, and the computer where the connection originates from is working fine as well. Any ideas?

  • Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedor

    - by Jim Dobbs
    Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

  • network user isolation

    - by seaquest
    My question is for a network with a Linux iptables router gateway. How can it be possible to prevent inter-network traffic of those users. Think this case as a public network, IPs are distributed through linux gw and users are authenticated thru the gateway. We want to protect public users from public users. Network is not wireless and I can not use Wireless AP user isolation. Actually I have a simple method. Subnet the network into /30 mask. Give minimum IP of each subnet to the gateay and ditribute those /30 IPs from the subnet. But this is pretty costly for such an aim. I want to ask for other methods Thanks.

  • Excel IP address and subnet to network and inverse mask [closed]

    We need a script, marco or something in excel where we can take list like below interface Vlan100 ip address 192.168.1.3 255.255.255.0 interface Vlan101 ip address 192.168.2.3 255.255.255.128 interface Vlan102 ip address 192.168.2.130 255.255.255.128 interface Vlan103 ip address 192.168.3.3 255.255.255.240 etc... and produce a list like below ospf 1 undo silent-interface Vlan-interface100 undo silent-interface Vlan-interface101 undo silent-interface Vlan-interface102 undo silent-interface Vlan-interface103 area 0.0.0.0 network 192.168.1.0 0.0.0.255 network 192.168.2.0 0.0.0.127 network 192.168.2.128 0.0.0.127 network 192.168.3.0 0.0.0.15 so it will need to take an ip address/subnet mask and convert them to network number/inverse mask. I believe I can handle the Vlan manipulation with a substitution so no need to spend time on that.
