  • Why does Ubuntu keep trying to connect to a WiFi network while plugged into an ethernet

    - by labarna
    My desk is situated at the edge of the range of a wireless signal which I use occasionally (when away from my desk) and is therefore saved in network manager. At my desk, however, I plug into the ethernet cable. While I'm working the computer is constantly trying to join the wireless network and usually failing this results in two annoying behaviors. 1: In gnome shell the network connect and disconnect notices keep popping up at the bottom of the screen and I have to click them to make them disappear (I assume it's been fixed in the next version of gnome). 2: (the worst!) Occasionally the wifi password dialog will pop up and ask for the password to this network (which is already saved). An additionally annoyance is that in gnome shell I'll get two copies of the dialog that I have to cancel, one is gnome shell themed (no window border etc...) and the other is just normal gnome themed. (Sometimes if I've been away from the computer for a while I will have multiple copies of this dialog up as its been trying to connect for a while resulting in at times 20 dialogs to cancel). Note, all the while I've been happily connected to the ethernet and have full network access. This is incredibly annoying and distracting, why doesn't ubuntu stop trying to connect to wifi if I'm on the ethernet (unless I want to broadcast my own network, but that's different)?

  • How to prevent Network Manager from auto creating network connection profiles with "available to everyone" by default

    - by airtonix
    We have several laptops at work which use Ubuntu 11.10 64bit. I have our Wifi Access Point requiring WPA2-EAP Authentication (backed by a LDAP server). I have the staff using these laptops when doing presentations by using the Guest Account. So by default when you have a wifi card, network manager will display available Wireless Access Points. So the logical course of action for a Novice(tm) user is to single left click the easy to use option in the Network Manager drop down list... At this point the Staff Member (who is logged in with the guest account) expects to just be able to connect and enter any authentication details if required. But because they are using the Guest account, they won't ever have admin permissions (nor do I want them to), and so PolKit kicks in with a request for admin authorisation. I solved this part by modifying the PolKit permissions required to allow all users to create System Network Connections... However, because these Staff members are logging onto the Wifi Access Point with Ldap Credentials and because the Network Manager is now saving those credentials as a System Connection, their password is available for the next guest user session (because system connection profiles are stored in /etc/NetworkManager/system-connections.d/* ). It creates system connections by default because "Available to all users" is ticked by default when you quickly connect to a new wifi access point. I want Network Manager to not tick this by default. This way I can revert the changes I made to Polkit and users network connection profiles will be purged when they log out.

  • Logging IP address for uniqueness without storing the IP address itself for privacy

    - by szabgab
    In a web application when logging some data I'd like to make sure I can identify data that came at differetn times but from the same IP address. On the other hand for privacy concerns as the data will be released publicly I'd like to make sure the actual IP cannot be retrieved. So I need some one way mapping of the IP addresses to some other strings that ensures 1-1 mapping. If I understand correctly then MD5, SHA1 or SHA256 could be a solution. I wonder if they are not too expensive in terms of processing needed? I'd be interested in any solution though if there is implementation in Perl that would be even better.

  • Computer Networks UNISA - Chap 15 &ndash; Network Management

    - by MarkPearl
    After reading this section you should be able to Understand network management and the importance of documentation, baseline measurements, policies, and regulations to assess and maintain a network’s health. Manage a network’s performance using SNMP-based network management software, system and event logs, and traffic-shaping techniques Identify the reasons for and elements of an asset managements system Plan and follow regular hardware and software maintenance routines Fundamentals of Network Management Network management refers to the assessment, monitoring, and maintenance of all aspects of a network including checking for hardware faults, ensuring high QoS, maintaining records of network assets, etc. Scope of network management differs depending on the size and requirements of the network. All sub topics of network management share the goals of enhancing the efficiency and performance while preventing costly downtime or loss. Documentation The way documentation is stored may vary, but to adequately manage a network one should at least record the following… Physical topology (types of LAN and WAN topologies – ring, star, hybrid) Access method (does it use Ethernet 802.3, token ring, etc.) Protocols Devices (Switches, routers, etc) Operating Systems Applications Configurations (What version of operating system and config files for serve / client software) Baseline Measurements A baseline is a report of the network’s current state of operation. Baseline measurements might include the utilization rate for your network backbone, number of users logged on per day, etc. Baseline measurements allow you to compare future performance increases or decreases caused by network changes or events with past network performance. Obtaining baseline measurements is the only way to know for certain whether a pattern of usage has changed, or whether a network upgrade has made a difference. There are various tools available for measuring baseline performance on a network. Policies, Procedures, and Regulations Following rules helps limit chaos, confusion, and possibly downtime. The following policies and procedures and regulations make for sound network management. Media installations and management (includes designing physical layout of cable, etc.) Network addressing policies (includes choosing and applying a an addressing scheme) Resource sharing and naming conventions (includes rules for logon ID’s) Security related policies Troubleshooting procedures Backup and disaster recovery procedures In addition to internal policies, a network manager must consider external regulatory rules. Fault and Performance Management After documenting every aspect of your network and following policies and best practices, you are ready to asses you networks status on an on going basis. This process includes both performance management and fault management. Network Management Software To accomplish both fault and performance management, organizations often use enterprise-wide network management software. There various software packages that do this, each collect data from multiple networked devices at regular intervals, in a process called polling. Each managed device runs a network management agent. So as not to affect the performance of a device while collecting information, agents do not demand significant processing resources. The definition of a managed devices and their data are collected in a MIB (Management Information Base). Agents communicate information about managed devices via any of several application layer protocols. On modern networks most agents use SNMP which is part of the TCP/IP suite and typically runs over UDP on port 161. Because of the flexibility and sophisticated network management applications are a challenge to configure and fine-tune. One needs to be careful to only collect relevant information and not cause performance issues (i.e. pinging a device every 5 seconds can be a problem with thousands of devices). MRTG (Multi Router Traffic Grapher) is a simple command line utility that uses SNMP to poll devices and collects data in a log file. MRTG can be used with Windows, UNIX and Linux. System and Event Logs Virtually every condition recognized by an operating system can be recorded. This is typically done using event logs. In Windows there is a GUI event log viewer. Similar information is recorded in UNIX and Linux in a system log. Much of the information collected in event logs and syslog files does not point to a problem, even if it is marked with a warning so it is important to filter your logs appropriately to reduce the noise. Traffic Shaping When a network must handle high volumes of network traffic, users benefit from performance management technique called traffic shaping. Traffic shaping involves manipulating certain characteristics of packets, data streams, or connections to manage the type and amount of traffic traversing a network or interface at any moment. Its goals are to assure timely delivery of the most important traffic while offering the best possible performance for all users. Several types of traffic prioritization exist including prioritizing traffic according to any of the following characteristics… Protocol IP address User group DiffServr VLAN tag in a Data Link layer frame Service or application Caching In addition to traffic shaping, a network or host might use caching to improve performance. Caching is the local storage of frequently needed files that would otherwise be obtained from an external source. By keeping files close to the requester, caching allows the user to access those files quickly. The most common type of caching is Web caching, in which Web pages are stored locally. To an ISP, caching is much more than just convenience. It prevents a significant volume of WAN traffic, thus improving performance and saving money. Asset Management Another key component in managing networks is identifying and tracking its hardware. This is called asset management. The first step to asset management is to take an inventory of each node on the network. You will also want to keep records of every piece of software purchased by your organization. Asset management simplifies maintaining and upgrading the network chiefly because you know what the system includes. In addition, asset management provides network administrators with information about the costs and benefits of certain types of hardware or software. Change Management Networks are always in a stage of flux with various aspects including… Software changes and patches Client Upgrades Shared Application Upgrades NOS Upgrades Hardware and Physical Plant Changes Cabling Upgrades Backbone Upgrades For a detailed explanation on each of these read the textbook (Page 750 – 761)

  • Password-free logins using your email address only?

    - by Mario
    The state of logins is horrendous. With each site having it's own rules for passwords, it can be very hard to remember what variation you used on any given site. Logins are pure pain. One thing I love about Craigslist is that it did away with logins altogether. I know this design may not suit every site, but there's something to their design that beckons to be repeated. OpenID is great on sites that have adopted it, but it's still not standard. Would it be feasible/wise to use an email address as a login and provide no password? The site would send a short-term key directly to your email address. You click on the link and you're in. When you're done, you "logout" and your key is terminated. I've toyed with this idea before. What concerns (i.e. spammers, bots, etc.) would make this impractical or unsafe and could they be overcome?

  • How to get rid of auto-generated sequence number in network's device name in Windows?

    - by Piotr Dobrogost
    Every time one plugs in the same usb wireless adapter in a new usb port, Windows creates new network device with auto-generated sequence number which looks like this Wireless-N USB Network Adapter #2, Wireless-N USB Network Adapter #3, ... The name of a device is being displayed as part of network's information in Control Panel|Network Connections. How can I get rid of this sequence number? I found out device name which is displayed in network's information is kept in the FriendlyName REG_SZ value under HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\USB\VID_[device specific string]\[usb port specific string] However when I try to modify this value I get error Cannot edit FriendlyName: Error writing the value's new contents. I tried to delete extra keys under HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\USB\VID_13B1&PID_0029 but got Cannot delete KEY NAME: Error while deleting key. error. Trying to solve this problem I followed this answer but trying to change owner with Replace owner on subcontainers and objects option checked I got this error - Registry Editor could not set owner on the currently selected, or some of its subkeys. To find out which subkey is the source of problem I tried changing owner of each subkey. After successfully changing owner of Properites subkey I saw it has subkeys which were previously hidden. Now trying to change owner of these subkeys looks like this: Any idea how to delete these keys?

  • JBoss 5.1 binds to host address while run in vserver with -b <guest address>

    - by bart cane
    Hello, while starting JBoss 5.1.0.GA in virtual server machine on Debian (linux-VServer technology) I get the following error: ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] (main) Error installing to Start: name=jboss.remoting:protocol=rmi,service=JMXConnectorServer state=Create mode=Manual requiredState=Installed java.io.IOException: Cannot bind to URL [rmi://10.1.2.11:1090/jmxconnector]: javax.naming.NoPermissionException [Root exception is java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.AccessException: Registry.Registry.bind disallowed; origin /AA.BB.CC.DD is non-local host] where AA.BB.CC.DD is host machine name, 10.1.2.11 is vserver guest with JBoss and JBoss is started with -b 10.1.2.11 (I also tried -Djboss.bind.address=10.1.2.11 - the same result). 10.1.2.11 is bound to dummy2 interface on host (serving 10.1.2.1 network). The root exception is strange - why JBoss wants to bind to host address AA.BB.CC.DD? There were no problems with 4.2.3.GA on the same machine, also started with -b 10.1.2.11. It starts correctly when no params present - binds to localhost and everything is ok, but it MUST be bound to 10.1.2.11 to be visible by Apache on another vserver guest, acting as proxy. I thought that it can be fixed by setting net.ipv4.conf.all.promote_secondaries=1 via sysctl (was 0) but it didn't help much. Has anyone had such problem? Regards, bart

  • Wired Network not working on Ubuntu 11.10 + Strange Behavior with Manual Conf

    - by Mauricio Cruz
    I'm new to Ubuntu - to be honest this is my very first day trying it... and I've already spent hours trying to make my wired connection work. I've been using this wired network with Windows and OSX, and in both systems I also had some trouble trying to connect in the past (and the troubleshooters did their magic and helped me get connected). Today, this is what I got: I'm running Ubuntu 11.10; ifconfig: eth0 Link encap:Ethernet HWaddr 78:2b:cb:c3:bf:8f UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:1 errors:0 dropped:0 overruns:0 frame:0 TX packets:343 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:70 (70.0 B) TX bytes:63273 (63.2 KB) Interrupt:20 Memory:e2e00000-e2e20000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1859 errors:0 dropped:0 overruns:0 frame:0 TX packets:1859 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:149368 (149.3 KB) TX bytes:149368 (149.3 KB) wlan0 Link encap:Ethernet HWaddr 10:0b:a9:82:55:c0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:15484 errors:0 dropped:0 overruns:0 frame:0 TX packets:16871 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:12048377 (12.0 MB) TX bytes:2677679 (2.6 MB) I also have some information from Windows ipconfig /all that I ran at my friend's machine Ipv6 Address: <address> preferential Ipv4 Address: 172.26.65.23 <preferential> Netmask: 255.255.254.0 Default Gateway: 172.26.64.1 DHCP Server : <address> DNS Servers : <address> DNS Suffix : <suffix> The weird thing is that I've tried to configure everything manually, using "Network Connections". When I add everything inside IPv4 Settings, the connection is finally successful, but only for 4~5 seconds before getting disconnected again... Update:I just changed the Connection Method to "Local-Link Only", and the same described above happens: At first, it says "Connection Stablished", but after a few seconds, the wired network gets disconnected. I hope someone can help me get connected! Thanks!

  • Network Manager kicks off abruptly

    - by Vijay Selvaraj
    I have installed Ubuntu 10.10 and trying to connect with my ADSL Wireless broadband internet modem using Linksys WUSB600N receiver. The good news is the OS is able to detect my wifi network and I am able to hook to network over WPA authentication with basic settings. But the network goes off abruptly and never connects again until I reboot the machine. I have Windows 7 as dual boot on my machine. The same adapter works perfectly with Windows 7 but not in Ubuntu. Is there anything in need to tweak to make things working or do I need to try any other better network manager on Ubuntu?

  • How do I disable network connection at prelogin?

    - by ProGNOMmers
    --- This question is related to Ubuntu 12.10, since previous versions did not connect to network before login --- I had a bad boot today: the Ubuntu screen was blocked at startup time, after a green [OK] and a white blinking underscore. In recovery mode I figured out the problem: NetworkManager hung trying to connect to a wireless network that wasn't available anymore, and so I couldn't reach the prelogin level. Anyway: I really don't like that the pc connects to a network before the user logging in. How is it possible to disable it?

  • Configuring Network without Default Gateway

    - by Homayoon
    I'm trying to connect my desktop and laptop using an ethernet connection. I usually configure network from the command line but this time I decided to give Network Manager a try, so I went to Network Connections, and selected manual IP configuration. At first I left the default gateway field blank, since I don't need a default gateway. Turned out network manager doesn't let me save the connection unless I enter that field, but entering a phony gateway messes up with my Internet connection. Anyway to do this setup?

  • Ubuntu 12.10 no network and no graphics

    - by khasiKoMasu
    I recently upgraded Ubuntu 12.04 to 12.10 only to find out that it won't connect to any network, neither wired nor wireless and the graphics is messed up too as in a low screen resolution.

    I have a Linux VPS, DirectAdmin as web panel and already set a domain to it. everything is OK and I can see my website in my browser using domain name. Now I need to have access to my site using its IP address. something like http://86.57.88.29, but when I try to load my site in a browser using its IP I get below message and I have to post-fix my IP with /~admin (http://86.57.88.29/~admin) to get it work. This IP is being shared among many domains. To view the domain you are looking for, simply enter the domain name in the location bar of your web browser. So how can I configure my IP to point to my public_html folder without and ~admin like phrase? Thanks.

  • Virtual PC network connection setting issue

    - by George2
    Hello everyone, I am using Virtual PC 2007 on Windows Vista Enterprise x86. My confusion is about the network setting for guest OS. In the network setting, I can set the network adaptor of guest OS to one of my physical network adaptors of my host OS (I have tested that it works for guest OS to use the physical network adaptor of host OS to access external network). But in this way, 1. since both host OS and guest OS will use the same physical network adaptor, will there be any conflicts (e.g. same H/W serves two OS)? 2. will guest OS share a part of network bandwidth of the host OS of the physical network adaptor? 3. What means NAT setting in guest OS network connection adaptor? thanks in advance, George

  • Building a Mac/PC Network in a Dorm with Network Restrictions

    - by user70340
    I have been a Windows XP user for the last few years, but I recently bought a 15'' MacBook Pro for research purposes. I would like to set up a no-hassle Mac/PC Network at home so that I can access the internet on both computers and hardware between computers (i.e. a harddrive, or a mouse/keyboard with Synergy). Unfortunately, I live in a dorm with silly network restrictions so a solution is not straightforward. In particular: The dorm has a wired and wireless network, both which provide an internet connection. The wired network provides way faster internet (download speeds of 15 MB/s vs. 2 MB/s on wireless), so I would like to somehow exploit this, at least on my PC for Bittorrent :) Multiple devices can connect to the wireless network, but cannot "see" each other on the network (so software like Synergy would not work). Only 1 MAC address can connect to the wired network at a time. Ideally I would just connect a wireless router to the wired network and then have both the Mac and the PC on that, but the 1 MAC address restriction will not allow the both computer to access the internet simultaneously. I cannot think of a way to bypass this restriction (though I'm not network savvy), so I am planning to create a private no-internet network to allow the devices to see each other and share hardware. Here are some thoughts. I would appreciate any feedback at all! If I build a private wireless network: (first choice) I will use a wireless router that is not connected to the internet. My PC and Mac will be connected to each other wirelessly. I can then connect the PC to the internet via a wired network, but then the Mac will not have internet access as its wireless card is already in use. In this case, could I stream internet access from the PC to the Mac via the wireless network? Or could I buy a USB wireless card for the Mac so that it can connect to both my private network and the dorm network? If I build a private wired network: (second choice) Then both the PC and the Mac will connect to the internet wirelessly, which means I cannot take advantage of the faster download speeds.

  • Use Network-Manager to Connect to a wifi Access Point on the command-line

    - by Stefano Palazzo
    I'd like to connect to a wireless access point from the command-line. ideally, I'd only need the name of the AP. But the hardware-address would work as well. I know I can use nmcli to connect to a managed network connection, but in my case, the access point may not be configured for Network-Manager yet (See the difference between the output of nm-tool and nmcli con). Example output of nmcli: Auto pwln 3a3d62b1-bbdf-4f76-b4d2-c211fd5cfb03 802-11-wireless [...] Wired Network aa586921-accf-4932-98c4-c873c310f08e 802-3-ethernet [...] Cisco-UDP Uni 7f94847b-04dc-40b7-9955-5246fb77cc65 vpn [...] T-mobile (D1) 867f345a-cbbf-4bd4-b883-a5e5ae0932f0 gsm [...] Example output of nm-tool: State: connected - Device: eth1 [Auto pwln] ---------------------------------------------------- [...] Wireless Access Points (* = current AP) *pwln: Infra, [...], Freq 2472 MHz, Rate 54 Mb/s, Strength 80 WPA WPA2 WLAN: Infra, [...], Freq 2422 MHz, Rate 54 Mb/s, Strength 20 WPA WPA2 [...] How do I connect to an access point that may or may not be known to NM? Extra: Finding out if the connection needs a pass-phrase, and submitting it on the command-line as well would be great too (that is to say It'd be nice if network-manager wouldn't pop open any keyring dialogues or errors on the gui)

  • Can't connect to hidden network with BCM4313

    - by poomerang
    The wireless works fine with all the other wi-fi nets I have tried, the only problem is with this hidden network. I should add it's the only hidden network I've tried, so I am not sure if the problem is it being hidden or somethings else, but I've checked the settings of NetworkManager against another Ubuntu system (which can connect) and they appear to be the same, passphrase included. The network is using WPA2 Personal with AES encryption, I don't know how to check this setting but I believe it's the usual for WPA2, and therefore usually not a problem. Also, I can connect through ethernet, which should exclude any blacklisting of my device, I believe. I usually use brcmsmac drivers, I've tried also STA but the result is the same. I've also tried the suggestion from Unable to connect to hidden SSID with no luck output of lspci -v is 03:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) Subsystem: Askey Computer Corp.
