• "/etc/init.d/networking restart" with non-root user

  - by bonchen

  I have a thin client with 112mb RAM which boots ubuntu server 12.04.1 from a usb drive with openbox and it is to be used by students to communicate with cisco equipment. And because of this the students need to be able to reconfigure the network interface and then restart it without a reboot using the only user - cisco. This is what I have so far: adduser cisco usermod -a -G dialout cisco chown root:cisco /etc/network/interfaces chmod 664 /etc/network/interfaces chmod u+s /sbin/shutdown chmod u+s /sbin/reboot chmod u+s /sbin/poweroff chmod u+s /run/network/if* chmod u+s /sbin/ifdown chmod u+s /sbin/ifup And when I run /etc/init.d/networking restart as cisco I get: *Reconfiguring network interfaces... rm: cannot remove `eth0.dhclient': Permission denied Failed to send flush request: Operation not permitted RTNETLINK answers: Operation not permitted Any ideas on how to get this working? Thanks!

• Should ATI catalyst be installed for sake of openCL?

  - by G Sree Teja Simha

  I have a HP Envy 4 1025tx with Hybrid graphics. Although this is a 64bit system, I've installed 32bit Ubuntu on it for some reasons.(Hybrid graphics don't do well with 64bit Ubuntu.-"Some one on some forum") I had heating problems with the GPU but I've fixed them all with vgaswitcheroo. But now I wanted to use my Blender on my Ubuntu. To my surprise Blender didn't detect the dedicated 7670m card in my machine. I've confirmed with cat /sys/kernel/debug/vgaswitcheroo/switch Both IGD and DIS were up and running. I dont seem to have libopencl on my /usr/lib even though my synaptic manager says that I have installed it. I'm not quite sure what I've installed. It says that I've installed "ocl-icd-libopencl1". So my question is... Do I have opencl on my system? If not do I have to get propreitary ATI drivers for sake of opencl(fglrx wrecks up my unity totally on my system I need directions to fix it if this is the choice)? Should I get a 64bit Ubuntu installed on this system?

• Implications of Cisco open-sourcing H.264? [on hold]

  - by Suman

  Cisco has announced that it will license and open-source the H.264 video codec. As a result of this, Firefox will be embedding H.264 playback functionality in future versions of Firefox. What implications, if any, will this have for programmers building software and/or hardware dealing with video (and WebRTC in particular)? (And if programmers.SE isn't the right forum, please feel free to suggest a better option.)

• CD/DVD drive not mounted when inserted with Disc of any kind

  - by Cisco Sán

  I just noticed that if a insert a CD or a DVD of any kind, the Drive will start spinning but it will not show the mounted disc. Before it used to ask me what to do with the media inserted. Now it doesn't even do that. I ran in the terminal this code: eject -n and it displays this: " eject: device is `/dev/sr0'" what can I do to get the functionality back on my drive. also ran this command: sudo mount -o ro,unhide,uid=1000 /dev/cdrom /mnt/cdrom but in return i get this: " mount: mount point /mnt/cdrom does not exist" Running Ubuntu 11.10 HERE IS THE HISTORY UNTIL NOW thanks Waltinator: I ran the 'dmesg' but don't know what I'm looking for. Im a newbie on this. The same thing with the 'ls -rlt /var/log' command. Should I create the directory for the mount? at this point really don't know what to do. – Cisco Sán 7 hours ago Here are 3 lines from my dmesg after I successfully inserted a CD: [ 4804.416018] wlan0: no IPv6 routers present [ 8214.125450] ISdit ISO 9660 Extensions: Microsoft Joliet Level 3 [ 8214.136556] ISO 9660 Extensions: RRIP_1991A The first line is a previous event, my wireless going online.

• How to Force Graphics Options in PC Games with NVIDIA, AMD, or Intel Graphics

  - by Chris Hoffman

  PC games usually have built-in graphics options you can change. But you’re not limited to the options built into games — the graphics control panels bundled with graphics drivers allow you to tweak options from outside PC games. For example, these tools allow you to force-enabling antialiasing to make old games look better, even if they don’t normally support it. You can also reduce graphics quality to get more performance on slow hardware. If You Don’t See These Options If you don’t have the NVIDIA Control Panel, AMD Catalyst Control Center, or Intel Graphics and Media Control Panel installed, you may need to install the appropriate graphics driver package for your hardware from the hardware manufacturer’s website. The drivers provided via Windows Update don’t include additional software like the NVIDIA Control Panel or AMD Catalyst Control Center. Drivers provided via Windows Update are also more out of date. If you’re playing PC games, you’ll want to have the latest graphics drivers installed on your system. NVIDIA Control Panel The NVIDIA Control Panel allows you to change these options if your computer has NVIDIA graphics hardware. To launch it, right-click your desktop background and select NVIDIA Control Panel. You can also find this tool by performing a Start menu (or Start screen) search for NVIDIA Control Panel or by right-clicking the NVIDIA icon in your system tray and selecting Open NVIDIA Control Panel. To quickly set a system-wide preference, you could use the Adjust image settings with preview option. For example, if you have old hardware that struggles to play the games you want to play, you may want to select “Use my preference emphasizing” and move the slider all the way to “Performance.” This trades graphics quality for an increased frame rate. By default, the “Use the advanced 3D image settings” option is selected. You can select Manage 3D settings and change advanced settings for all programs on your computer or just for specific games. NVIDIA keeps a database of the optimal settings for various games, but you’re free to tweak individual settings here. Just mouse-over an option for an explanation of what it does. If you have a laptop with NVIDIA Optimus technology — that is, both NVIDIA and Intel graphics — this is the same place you can choose which applications will use the NVIDIA hardware and which will use the Intel hardware. AMD Catalyst Control Center AMD’s Catalyst Control Center allows you to change these options on AMD graphics hardware. To open it, right-click your desktop background and select Catalyst Control Center. You can also right-click the Catalyst icon in your system tray and select Catalyst Control Center or perform a Start menu (or Start screen) search for Catalyst Control Center. Click the Gaming category at the left side of the Catalyst Control Center window and select 3D Application Settings to access the graphics settings you can change. The System Settings tab allows you to configure these options globally, for all games. Mouse over any option to see an explanation of what it does. You can also set per-application 3D settings and tweak your settings on a per-game basis. Click the Add option and browse to a game’s .exe file to change its options. Intel Graphics and Media Control Panel Intel integrated graphics is nowhere near as powerful as dedicated graphics hardware from NVIDIA and AMD, but it’s improving and comes included with most computers. Intel doesn’t provide anywhere near as many options in its graphics control panel, but you can still tweak some common settings. To open the Intel graphics control panel, locate the Intel graphics icon in your system tray, right-click it, and select Graphics Properties. You can also right-click the desktop and select Graphics Properties. Select either Basic Mode or Advanced Mode. When the Intel Graphics and Media Control Panel appears, select the 3D option. You’ll be able to set your Performance or Quality setting by moving the slider around or click the Custom Settings check box and customize your Anisotropic Filtering and Vertical Sync preference. Different Intel graphics hardware may have different options here. We also wouldn’t be surprised to see more advanced options appear in the future if Intel is serious about competing in the PC graphics market, as they say they are. These options are primarily useful to PC gamers, so don’t worry about them — or bother downloading updated graphics drivers — if you’re not a PC gamer and don’t use any intensive 3D applications on your computer.

• IPsec VPN tunnel between Windows 2008 R2 and CISCO ASA?

  - by antur123

  I need to create a VPN IPsec tunnel between my Windows 2008 R2 server and a CISCO ASA device. I want my server to be both the end of the tunnel, and the server that connects to the other side (no need to connect a whole subnet, just the server would be fine). I found this article that seems to do the trick, but there are two differences: As mentioned above, the computer behind my end is the server itself. Can that be configured? (i.e. make the "computers in endpoint 1" IP address be the same than "local tunnel computer"). This article is for Juniper ScreenOS, not for CISCO ASA, though configurations look very similar. Would that configuration work for me?

  - by user69670

• I dont get the Graphics software

  - by Nicky Bailuc

  I have AMD Radeon HD 4850, with the latest drivers. I just dont get several things, what is x.org? What is FGLRX? Also, what is RandR? And why in the info section of the control centre it says Catalyst version is 12.6, but Catalyst control centre is 2.14, what is the difference between Catalyst and Catalyst control centre? Also, why is the Driver packaging version 8.98 while the Driver package says 12.6? I am extremely confused! As well as in the installer, what is the difference between choosing "Install Driver 8.98 on X.Org 6.9 or later" and "Generate Distribution Specific Driver Package"?

• Error using Dynamic Data Filtering: missing datasource

  - by sebastiaan

  I am trying to use the ASP.NET Dynamic Data Filtering project, but I'm running into a problem during the configuration. I'm following the instructions on the author's blog, and everything works like described. Then it tells me to change the datasource using the designer view. I am told to select the "GridDataSource" in the "Configure data source" wizard. This option is not there though. I get all of the classes in my project, including the DataContext that was generated by Linq. When I choose "Show only DataContext objects", the dropdown ("Choose your context object:") is completely empty. When I turn of the checkbox and choose my DataContext class, I get asked which table I want and all that. But, as the whole purpose of a Dynamic Data site is NOT to use one single table, that's not much help. So I've looked at the instructions again and copied the resulting datasource from the example: <asp:DynamicLinqDataSource ID="GridDataSource" runat="server" EnableDelete="True" EnableUpdate="True"></asp:DynamicLinqDataSource> Which is exactly what I had, without the "WhereParameters" nodes in there. Now, when I run the list page however, I get an exception about a missing datasource from the filtering component. Of course when I remove the DynamicFilterRepeater, it works again. This is the meat of the exception: [InvalidOperationException: Missing DataSource] Catalyst.Web.DynamicData.DynamicFilterRepeater.GetTable() in D:\Catalyst\Projects\DynamicData\Project\Trunk\DynamicData\DynamicData\DynamicFilterRepeater.cs:74 Catalyst.Web.DynamicData.DynamicFilterRepeater.GetFilters() in D:\Catalyst\Projects\DynamicData\Project\Trunk\DynamicData\DynamicData\DynamicFilterRepeater.cs:81 Catalyst.Web.DynamicData.DynamicFilterRepeater.OnInit(EventArgs e) in D:\Catalyst\Projects\DynamicData\Project\Trunk\DynamicData\DynamicData\DynamicFilterRepeater.cs:106 How do I make the DynamicFilterRepeater recognize my datasource?

• Connectiong adsl router/modem and router with bridgemode

  - by Zvonko Telefonko

  I have one adsl modem/router which is not "top" of the line and it lack allot of options which I need. I was able to acquire one Cisco router recently which has all options that I need ( like DMZ, VPN, port forwarding, etc). I'm interested, if I connect the old modem/router to new Cisco router using bridge mode, will I be able to use all the features on the Cisco? For instance, the old router is lacking of port forward options. Does this mean that I will not be able to use port forwarding on Cisco router either or, since I will be using bridge mode, this will not affect Cisco router and it will work as the modem is in him? thank you

• Facing issues in setting up VPN connection(IKEv1) using iphone (Defult Cisco VPN client) and Strongswan 4.5.0 server

  - by Kushagra Bhatnagar

  I am facing issues in setting up VPN connection(IKEv1) using iPhone (Defult Cisco VPN client) and Strongswan 4.5.0 server. The Strongswan server is running on Ubuntu Linux, which is connected to some wifi hotspot. This is the guide which was used. I generated CA, server and client certificate, with the only difference mentioned below. “While generating server certificate, as per link CN=vpn.strongswan.org instead of this I changed CN name to CN=192.168.43.212.” Once certificates are generated, following (clientCert.p12 and caCert.pem) are sent to mobile via mail and installed on iphone. After installation I notice that certificates are considered as trusted also. Below are the ip addresses assigned to various interfaces Linux server wlan0 interface ip where server is running: 192.168.43.212 Iphone eth0 interface ip address: 192.168.43.72. iphone is also attached with the same wifi hotspot. Below is the snapshot of client configurations. Description Strong swan Server 192.168.43.212 Account ipsecvpn Password ***** Use certificate ON Certificate client The above username and password are in sync with the ipsec.secrets file. I am using the following ipsec.conf configuration: # basic configuration config setup plutodebug=all # crlcheckinterval=600 # strictcrlpolicy=yes # cachecrls=yes nat_traversal=yes # charonstart=yes plutostart=yes # Add connections here. # Sample VPN connections conn ios1 keyexchange=ikev1 authby=xauthrsasig xauth=server left=%defaultroute leftsubnet=0.0.0.0/0 leftfirewall=yes leftcert=serverCert.pem right=192.168.43.72 rightsubnet=10.0.0.0/24 rightsourceip=10.0.0.2 rightcert=clientCert.pem pfs=no auto=add With the above configurations when I enable VPN on iphone, it says Could not able to verify server certificate. I ran Wireshark on a Linux server and observe that initially some ISAKMP message exchanges happens between client and server, which are successful but before authorization, client is sending some informational message and soon after this client is showing error as popup Could not able to verify server certificate.

• Windows Server 2008 R2 install reboots unexpectedly during "Completing installation" phase

  - by knda

  I am attempting to install Windows Server 2008 R2 onto a Cisco UCS C201 M2 rack mounted server but am having major difficulties and wondering if anyone has some insight or items they could recommend for me to look at to get this one resolved. Installation is being attempted via the Cisco remote console (using CIMC's Virtual dvd-rom).. following the first phase of Setup where the installation files are copied to the target hard drive, then a reboot occurs to load Setup from the HDD, mid-way in the "Completing Installation" phase the system then reboots unexpectedly. System configuration Cisco UCS C201 M2 (2RU rack mounted server) 16GB RAM, 2x 73GB 15K SAS, 4x 300GB 10k SAS Add-on cards - Intel quad-port GigE card (no fibre channel cards) Storage - LSI MegaRAID SAS 9261-8i. onboard SATA is disabled (no SATA drives connected) KVM - Belkin No physical DVD-ROM.. :( I have... Run memtest86+, no RAM faults Disabled/enabled SATA support (BIOS) Attempted install from USB DVD-ROM, no effect Attempted unattended install scripted via Cisco Configuration Manager DVD provided Removed Belkin KVM in case that was causing drama Discovered that the Cisco website is "awesome" for searching for PDFs/Drivers cough, reverted back to Google Downloaded latest LSI drivers from LSI's site and used during Server 2008 install checked Windows ISO against checksum's from MS site checked Windows ISO by using it for an install in a VM Running out of ways to troubleshoot this as I am not sure how to enable any sort of 'verbose' mode during the setup process. Next step I have planned is to remove the Intel NIC and try the installation again.. Edit: Problem was the "Cisco INTEL QUAD PT GBE" (1000/PT) .. will have to see if this card is faulty or if it's just drivers.. thanks for the help.

• Other Ideas to troubleshoot Cisco IPSec VPN on OSX?

  - by Tawm

  We have one user running OSX Snow Leopard who is having issues staying connected to our VPN running off of an ASA5510. His connection can die even as he's actively pushing traffic across it or if he's been idle for a period of time.

• How to get bearable 2D and 3D performance on AMD Radeon HD 6950?

  - by l0b0

  I have had an AMD Radeon HD 6950 (i.e., Cayman series) for a couple years now, and I have tried a lot of combinations of drivers and settings with terrible results. I'm completely at a loss as to how to proceed. The open source driver has much better 2D performance, but it offloads all OpenGL rendering to the CPU. What I've tried so far: All the latest stable Ubuntu releases in the period, plus one Linux Mint release. All the latest stable AMD Catalyst Proprietary Display Drivers, and currently 13.1. The unofficial wiki installation instructions for every Ubuntu version and the semi-official Ubuntu instructions. All the tips and tweaks I could find for Minecraft (Optifine, reducing settings to minimum), VLC (postprocessing at minimum, rendering at native video size), Catalyst Control Center (flipped every lever in there) and X11 (some binary toggles I can no longer remember). Results: Typically 13-15 FPS in Minecraft, 30 max (100+ in Windows with the same driver version). Around 10 FPS in Team Fortress 2 using the official Steam client. Choppy video playback, in Flash and with VLC. CPU use goes through the roof when rendering video (150% for 1080p on YouTube in Chromium, 100% for 1080p H264 in VLC). glxgears shows 12.5 FPS when maximized. fgl_glxgears shows 10 FPS when maximized. Hardware details from lshw: Motherboard ASUS P6X58D-E CPU Intel Core i7 CPU 950 @ 3.07GHz (never overclocked; 64 bit) 6 GB RAM Video card product "Cayman PRO [Radeon HD 6950]", vendor "Hynix Semiconductor (Hyundai Electronics)" 2 x 1920x1200 monitors, both connected with HDMI. I feel I must be missing something absolutely fundamental here. Is there no accelerated support for anything on 64-bit architectures? Does a dual monitor completely mess up the driver? $ fglrxinfo display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: AMD Radeon HD 6900 Series OpenGL version string: 4.2.11995 Compatibility Profile Context $ glxinfo | grep 'direct rendering' direct rendering: Yes I am currently using the open source driver, with the following results: Full frame rate and low CPU load when playing 1080p video. Black screen (but music in the background) in Team Fortress 2. Similar performance in Minecraft as the Catalyst driver. In hindsight obvious, since both end up offloading the rendering to the CPU. My /var/log/Xorg.0.log after upgrading to AMD Catalyst 13.1. Some possibly important lines: (WW) Falling back to old probe method for fglrx (WW) fglrx: No matching Device section for instance (BusID PCI:0@3:0:1) found The generated xorg.conf. The disabled "monitor" 0-DFP9 is actually an A/V receiver, which sometimes confuses the monitor drivers when turned on/off (but not in Windows). All three "monitor" devices are connected with HDMI. Edit: Chris Carter's suggestion to use the xorg-edgers PPA (Catalyst 13.1) resulted in some improvement, but still pretty bad performance overall: Minecraft stabilizes at 13-17 FPS, but at least the CPU load is "only" at 45-60%. Still 150% CPU use for 1080p video rendering on YouTube in Chromium. Massive improvement for 1080p H264 in VLC: 40-50% CPU use and no visible jitter glxgears performance about doubled to 25-30 FPS when maximized. fgl_glxgears still at ~10 FPS when maximized.

• What does it mean for the file name to be shown with red background

  - by user56614

  I'm trying to install Cisco VPN client on Linux Ubuntu 10.04. The installer creates the directory, places all the necessary files in it, and then fails to launch the binary. I tried to launch it myself, the system rebukes me too. Closer inspection yields the following: eugene@eugene-desktop:/opt/cisco/vpn/bin$ sudo chmod u+x vpnagentd eugene@eugene-desktop:/opt/cisco/vpn/bin$ ls -la total 5124 drwxr-xr-x 2 root root 4096 2010-10-23 11:51 . drwxr-xr-x 6 root root 4096 2010-10-23 11:51 .. -rwxr-xr-x 1 root root 1607236 2010-10-23 11:51 vpn -rwsr-xr-x 1 root root 1204692 2010-10-23 11:51 vpnagentd -r--r--r-- 1 root root 697380 2010-10-23 11:51 vpndownloader.sh -rwxr-xr-x 1 root root 1712708 2010-10-23 11:51 vpnui -rwxr-xr-x 1 root root 3654 2010-10-23 11:51 vpn_uninstall.sh eugene@eugene-desktop:/opt/cisco/vpn/bin$ ./vpnagentd bash: ./vpnagentd: No such file or directory eugene@eugene-desktop:/opt/cisco/vpn/bin$ sudo ./vpnagentd sudo: unable to execute ./vpnagentd: No such file or directory The file name "vpnagentd" is shown in white letters with red background. The other three executables are in green letters with black background, as expected. Any ideas?

• Replacing sick NTP server source and re-synching (with internal time currently 2 minutes late)

  - by l0c0b0x

  One of the external NTP servers (the primary one--currently) we're using as source seems to not be responding to NTP calls. Unfortunately, on our core router (Cisco 6509), the NTP functionality hasn't switched to the secondary NTP external server as it was expected. As a result, our core router which is pretty much our main internal NTP source is 2 minutes late. I'm planning to fix the external router issue by making the external NTP source be the one currently working. I'm wondering, how much will a 2 minute change affect my users and services? Specially since these days, we're heavily relying on certificate-based authentication. We're a Windows/Cisco shop. Internal NTP setup: [Core Router 1 / Cisco 6509]: looking out to two external NTP servers (in which the primary one is not responding to NTP calls) [Core Router 2]: Synching with Core router 1 (primary), working external router (secondary) [Other Cisco network devices]: Synching with Core router 1 (primary), core router 2 (secondary) [Domain controller(s)]: Synching with Core router 1 [All windows clients/servers]: Synching with domain controllers

• Use jQuery and ASP.NET to Build a News Ticker

  Many websites display a news ticker of one sort or another. A news ticker is a user interface element that displays a subset of a list of items, cycling through them one at a time after a set interval. For example, on Cisco's website there is a news ticker that shows the company's latest news items. Each news item is a one sentence link, such as "Desktop Virtualization Gathers Steam," or "Cisco Reports First Quarter Earnings." Clicking a headline whisks you to a page that shows the full story. Cisco's news ticker shows one headline at a time; every few seconds the currently displayed headline fades out and the next one appears. In total, Cisco has five different headlines - the ticker displays each of the five and then starts back from the beginning. This article is the first in a series that explores how to create your own news ticker widget using jQuery and ASP.NET. jQuery is a free, popular, open-source JavaScript library that simplifies many common client-side tasks, like event handling, DOM manipulation, and Ajax. This article kicks off the series and shows how to build a fairly simple news ticker whose contents can be specified statically in HTML markup or created dynamically from server-side code. Future installments will explore adding bells and whistles, such as: stopping the news ticker rotation when the mouse is hovered over it; adding controls to start, stop and pause the headlines; loading new headlines dynamically using Ajax; and packaging the JavaScript used by the ticker into a jQuery plugin.

• Why does ATI 5570 HD video card driver installation cause Windows 7 To Blue Screen?

  - by Mort

  This one is for the hive mind. I have a brand new Dell Optiplex 760 workstation with 4 gigabytes of RAM running Windows 7 Professional (32bit). This is a new box with nothing installed other than what was provided for directly by Dell. I installed a Saphire ATI PCI Express 5570 HD. Upon trying to install the 10.4 Catalyst drivers the system will blue screen. It blue screens during the hardware detection phase of the installation process. I have already performed the following trouble shooting steps: Changed system RAM Installed only 2 gigabytes of RAM Installed different versions of Catalyst drivers (10.4 - 9.12) Tried to install video only component of driver (vs entire Catalyst suite) Made sure Windows 7 was fully updated Flashed mother board BIOS to current version Removed and re-seated video card Contacted ATI Support (We all know how this went......) Verified supply outputting properly The blue screen error (via Windows BugCheck entry in event log) is a 0x000000CA and refers to a plug and play error most likely caused by a bad driver. The problem is that the driver installation process never gets far enough to actually install a driver. The resolution center in Windows provides a solution of installing the 10.4 Catalyst driver to resolve issue (which fails). Looking for some alternate views to resolve.

• ATI Radeon HD 6870 Driver fails to install default-policy.sh does not support version

  - by Rogue Coder

  I'm running Ubuntu 11.04 Beta, with everything updated completely. I'm using Ubuntu Classic, because Unity fails to run, supposedly because of my video card. The drivers for the Radeon HD 6870 series is apparently lacking, but I found a post stating the newest version has full support for Ubuntu Natty Narwhal. That post is slightly old, so i grabbed 11.3 for Ubuntu x86 off the ATI website.
