  • Failed to compile Network Manager 0.9.4

    - by Oleksa
    After upgrading to 12.04 I needed to re-compile Network Manager to the version 0.9.4.0 again. However with the version 9.4.0 I faced with the error during compilation with libdns-manager: $ make ... Making all in dns-manager make[4]: ????? ? ???????

  • Remote location looses connectivity

    - by user24559
    I have a remote location that has constant internet access using DSL. The remote location only has three Linksys cameras that use the internet access with a router. There is no computer on the network. The router is configured to use the DYN.org service to keep the IP address updated if the internet provider assigns a new ip address. The problem I am having is the router after a period of time stops responding to incoming ping requests and the cameras are shown offline. However, if I keep one of the cameras constantly streaming data then the connection to all the cameras works just fine all the time. How can I keep the router from appearing to be sleeping and not responding to incoming requests? The router is the Linksys WRT300N.

  • Network connectivity issue

    - by kubiej21
    I am a novice cisco user and I am trying to investigate as to why one of our connections went down. We have a fiber network ring that is operating just fine. Connected to this ring via ethernet, is a lone 3560. This connection has worked flawlessly for the past year and a half. This morning, I noticed that I could not connect to that remote switch. I checked the configurations on both switches, and nothing has changed (as I expected). In the field, the port lights were flashing, indicating that some sort of communication is occurring. There is only 1 ethernet cable that has been run between these two locations, so testing an alternate path is not possible. What else can I do to fix this connection?

  • Nice network diagram editor?

    - by Nicolas Raoul
    Writing a commercial proposal, I want to create a nice graphic showing the clients the architecture I thought of for their IT network, with servers, network connections, firewall, load-balancing, etc. For years I have been using dia, but I am tired of it, the results are not satisfying, very few network elements are available, and each element's graphic representation is really ugly. Question: How to create nice network diagrams? If a better set of elements was available for dia, that would be a solution.

  • How to make ad-hoc network connection?

    - by Johan Nathaniel Soedjono
    I can't make ad-hoc from my netbook (Ubuntu 12.04). It has internet source from ethernet. I have tried making from network manager. But it always says 'Wireless Network Disconnected' and can't be detected by neither my other laptop nor my cell phone which have wifi. How can I make adhoc from it? I have already tried making a connection in Network Manager a lot of times, but it still can't connect and appear notification 'Wireless Network Disconnected'.

  • Configuration of the network manager via DBus: how to set the ad hoc mode

    - by Andrea
    I have an hard nut to crack: a nice bottle of italian Chianti wine to the solver! :) To automatically configure Wifi, I first have to kill the network manager and than activate the wifi via the commandline: I do this all automatically in my application and works great. However... it is not the right way to do this. As the user has no network gui anymore to configure some other network access. A much better and transparent way would be to configure wifi directly via network manager over the DBus interface. I was able to configure it, but I wasn't able to set it to ad hoc mode... Searching the web for a while: a lot about configuration in general but nothing related to ad hoc mode. I think the only way to do figure that out is to look into the source code of the network manager...maybe someone already did it and he can answer.

  • Manually activate Network Manager Applet

    - by diosney
    The issue I've is that when I connect via modem through gnome-ppp the Network Manager Applet don't detect a connection and don't let me use the configured VPNs via its interface. How Can I manually activate the Network Manager Applet? What I need is to enable the Network Manager apple in order to use the "VPN Connection" section of the GUI. When I don't have an ethernet cable connected and I connect through a modem the Network Manager applet doesn't enables itself, it is like if don't recognizes the ppp0 interface. My question is: there is a way to force the Network Manager GUI indicator to make it "alive"/"up"/"enabled" in order to use the "VPN Connections"section? Thanks in advance.

  • Network Manager troubleshooting

    - by Anero
    I'm having some issues when connecting to my house's wifi from my Ubuntu 10.10 laptop. If the connection doesn't exists, when selecting the network (and after entering the WPA2 password) I'm able to connect. Once the connection is saved, when trying to reconnect, Network Manager works for a minute or so and then fails; the only way to reconnect then is to delete the saved connection and re-select the network from the list of available wireless networks. The same network works with no issues on the same laptop when running Win7, and on other wireless networks when running Ubuntu. Is there a Network Manager log which I can take a look at for troubleshooting the issue? Are there any tools for checking the wifi status?

  • Computer Studdering When Transferring Over Network

    - by Nalandial
    This is a really weird problem that I've never even seen before. When I copy to or from my server share, my computer studders terribly and the data transfers very slowly at only around 12MB/s. By studdering I mean the mouse skips around and all my applications respond very slowly; as soon as I cancel the transfer it resolves immediately. I looked at Task Manager and the CPU is only at ~35% with plenty of RAM free. This only started semi-recently; before, I had no problems and the transfer speed maxed out the gigabit connection. I have two hard drives in my computer. When I try transferring files between drives it's fine, but when I copy from the share to either drive or to it from either drive, I get studdering. I'm running Windows 7 x64. Anyone have any idea what's going on? Any help would be much appreciated.

  • Network Issues only on one network with a Broadcom BCM4312

    - by Ryan McClure
    My Ubuntu 11.10 laptop is having network connection issues...only on one network. I have a BCM4312 card and I'm using the proprietary driver. Whenever I connect to a network over wireless connection, I have no trouble except for one network. In my dorm, if I try to connect to the wireless network, it stays connected from anywhere to 30 seconds to 30 minutes before it will still be "connected" according to the indicator but there is no incoming/outgoing internet connection. This only happens in this building. Other networks with the same name at other buildings on my campus have no issue whatsoever. I took it to the tech department here and they keep claiming it's my laptop; but, if I can connect to other networks with absolutely no issues, why can't my laptop connect here? So, here's my question: Is it my laptop, or is it the network? As a side note, no one else that I know has issues on this network but one; she's running Windows 7 and I forget what kind of laptop it is. One of the people in my hall runs Ubuntu 12.04 and has no problem with the wireless. What do you all think of this?

  • 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.

  • How can I debug a port/connectivity issue?

    - by rfw21
    I am running a simple WebSocket server on Amazon EC2 (Fedora Core). I've opened the relevant port using ec2-authorize, and checked that it's opened. Iptables is definitely not running. However I can't connect to the port from outside EC2. I've tried the following (my server is running on port 7000): telnet ec2-public-dns.xx.xx.xx.amazon.com 7000 (from within EC2: connects fine) nmap localhost (output includes line: 7000/tcp open afs3-fileserver) telnet ec2-public-dns.xx.xx.xx.amazon.com 7000 (this time from my local machine: I get "connection refused: Unable to connect to remote host") The strange thing is this: if I start Nginx on port 7000 then it works and I can connect from outside EC2! And the WebSocket server fails on port 80, where Nginx works fine. To me this suggests a problem with the WebSocket server, BUT I can connect to it successfully from within EC2. (And it works fine on a different VPS account). How can I debug this further? If anybody can stop me tearing my hair out, I'd be very grateful indeed :)

  • Bluetooth connectivity

    - by Viniketa
    computer: Samsung All in One PC OS: Windows 7 (up-to-date) BT Radio: Broadcom I have Bluetooth speakers I have successfully used with the system in the past. In fact, I had them set as default speakers so audio would transfer when I turned them on. No longer. Now, they show as 'disconnected'. Asking for connection gives no response. Option to set as default is greyed out. Bluetooth view utility gives an error of 10049 when I try to connect (supposedly, the means an invalid device address). I uninstalled the device and re-installed. No help. Any advice? Thanks in advance.

  • 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)

  • 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?
