• Best neural network for certain type of pattern analysis?

  - by fred basset

  Hi All, I'm working on a system that will send telemetry data on machine operation back to a central server for analysis. One of the machine parameters we're measuring is motor current drawn vs time. After an operation is finished we plan to send back an array of currents vs time to the server. A successful operation would have a pattern like a trapezoid, problematic operations would have a pattern completely different, more like a large spike in values. Can anyone recommend a type of neural network that would be good at classifying these 1D vectors of current values into a pass/fail type output? Thanks, Fred

• Many network adapters at machine, need to find one that is used for traffic in Windows (from .net)

  - by viko

  My application use Web-service. I'm control from what workstation was request and for this send MAC-Address how parameter of all methods. But then I start testing application in real, I found workstations which have many network adapters - Ethernet, Wireless, Bluetooth. When I get MAC-address using next code: var networkAdapters = NetworkInterface.GetAllNetworkInterfaces(); if (networkAdapters == null || networkAdapters.Length == 0) return string.Empty; string address = string.Empty; foreach (var adapter in networkAdapters) { var a = adapter.GetPhysicalAddress(); if (a != null && a.ToString() != string.Empty) { address = a.ToString(); break; } } return address; Sometimes Web-service receive from workstation different MAC-Addresses, but I want get always only one MAC-address. Please, help me.

• Networking is disabled after installing Maverick

  - by Zifre

  I recently installed Ubuntu 10.10 (Maverick Meerkat). Everything was working fine. Then I just started up the computer again, and the networking doesn't work. The network manager applet says "Networking disabled". The button is disabled, so I can't enable it. This question seems to be basically the same issue I have. managed in was set to false, but changing it to true does not fix the problem. Is there any other way to fix this problem?

• Can I share a TV card?

  - by Boris

  My environment: 2 PCs, a desktop and a laptop, both on Oneiric they are connected together by ethernet wire nfs-common is installed and configured: the desktop is the server a TV tuner card is installed on the desktop, I can watch TV with the software Me-TV It works fine, TV on desktop, and my network too: I share folders thanks to NFS. But I would like more: How can I share my TV tuner card from the desktop and be able to watch TV on the laptop too? If possible I would like a solution that allows me to keep using the software Me-TV, on both PCs. I bet that there is a solution to create a fake TV card on the 2nd PC with xNBD. I'm trying xnbd-server --target /dev/dvb/adapter0/demux0 but I cant make it work. Trying to understand some examples of xNBD command lines, it seems to be meant only for sharing disk player. If someone as ever used xNBD, he's welcome.

• Wifi hotspot to connect to Android using non-AP supported cards

  - by 3l4ng

  I'm running Ubuntu 13.10 64b on a Dell Inspiron N5010. My wireless device (found using lspci) is Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01). I bought a new android phone and want to connect to Internet by using the laptop as a Wireless Access Point (ad-hoc doesn't work with Android). I tried following tutorials like the one at How to setup a wi-fi hotspot (access point mode)?. The relevant output from iw list was Supported interface modes: * IBSS * managed Running sudo hostapd /path/to/conf/file gave me (eth1 is the wireless, verified by iwconfig) Failed to create interface mon.eth1: -95 (Operation not supported) Could not set channel for kernel driver eth1: Unable to setup interface. Could not connect to kernel driver. I am able to use Connectify and Virtualrouter on Windows, and the phone works great. How do I get an access point running on Ubuntu? I'm open to other alternatives as well.

• How to enable true remote login

  - by Scán

  I don't quite know how these things are called, so a search did not product any help. I've got two computers, a desktop and a netbook. The netbook is really weak, and there's hardly any fun doing work with it, especially after ubuntu software swallows so much cpu power for nothing. But my desktop is good, but uncomfortably positioned. So I know you can use any linux system as a server to give logins. I want to be able to login and work on my desktop, from my netbook. No VNC, no SSH, full X-server, I want to be able to choose "Login on Desktop" in my login menu on the netbook and have everything as if I was there. I hope I could make my point. Is it possible in a local network? And if so, how can I easily set it up?

• Ubuntu 12.10 64bit fresh install, wireless issue!

  - by Dave

  Just installed a fresh Ubuntu 12.10 64bit on my laptop, run the update manager, restarted and suddenly I can't use my wifi anymore. Ubuntu software center installed automatically the wifi additional driver as you can see in my screenshot. If I mark the option "Do not use the device" and apply changes, restarting Ubuntu my wifi is back and I can use it. If I run iwconfig my terminal is showing this Now if I use Ubuntu for more than 20 minutes surfing the web my wifi it keeps to be connected but I don't receive any signal from it. Any page I try to open it simply don't open (just waiting icon). If I disconnect my wifi and connect it again, same issue, it doesn't work. The only way to make it work again is to restart Ubuntu. And the same story it happens again after aprox. 20, 30 minutes. WIFI device details: 03:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01) Thanks, Dave

• How do I fix DNS resolving which doesn't work after upgrading to Ubuntu 13.10 (Saucy)

  - by Witek

  After upgrade to 13.10 my DNS resolving fails. It seams the DNS servers which I get by DHCP (LAN) are not used. I could temporary solve the problem by adding nameserver 8.8.8.8 to /etc/resolv.conf. But then the intranet hosts still can not be resolved. When clicking on the Connection Information menu item on the network indicator, the Primary DNS and the Secondary DNS are set correctly. But my computer seams not to use them. So my questions: What should I put into resolv.conf, if anything? How to find out, which name servers my computer is querying? Where to look next, to find out, why name servers received by DHCP are not used?

• Networkmanager in systray gone and sound not working after update 13.10

  - by rubo77

  After upgrading my Xubuntu 13.04 to 13.10 I have no sound. I still have sound if I start VLC with sudo mpg123 test.mp3 So it seemd there is a right problem EDIT after adding myself to the group audio with adduser myself audio I could play sounds again from the desktop with VLC But one problem remaining: The systray, usually looking like this: is not working anymore. No audio-settings and no network-manager in the taskbar in XFCE: there is just one small box with nothing in it. When I install stalonetray, There I see the status of wicd and all the other statuses, so the systray seems to be broken.

• Jquery website is not opening in UBUNTU but in XP, Everything is fine

  - by Raman Sethi

  I know it is weird, But I just discovered this, jquery.com is not opening in my ubuntu firefox or other KDE browser and hence many sites that copy codes from code.jquery.com also hanged. Is there any solution to this problem. I have found the problem It is actually with the DNS servers I am using, Google DNS, 8.8.8.8 and 8.8.4.4, whenever I use these DNS in ubuntu my system stop responding to some sites, actually they are connected nicely, but the request end up in waiting.. I dont understand why...??? I checked my DNS with cat /etc/resolv.conf Even after using Google DNS, it is showing DNS servers I received automatically after connecting to the service provider. I am connecting using Network Manager, not using DNS I provided but using the default one. Any Solution??

• How to set up bridged networking in Xen?

  - by Joe Carr

  I have 2 domU virtual machines installed on a 11.10 Oneiric Dom0. My internal network is on the 192.168.1 subnet, and when the domU's start, they get ips on the 192.168.122 subnet. I have attempted to follow the instructions here : http://wiki.kartbuilding.net/index.php/Xen_Networking xend-config.sxp is configured correctly, but neither of my domU's have a config file in /etc/xen to modify. ifconfig reports that I have the following devices : eth0, lo, tap3.0, vif3.0, vif4.0, virbr0 bridge-utils is installed. I also just attempted to follow these steps : http://serverfault.com/questions/233201/bringing-the-xenbr0-interface-up-on-xen-under-ubuntu-8-04 sudo brctl addbr xenbr0 sudo brctl addif xenbr0 vif3.0 device vif3.0 is already a member of a bridge; can't enslave it to bridge xenbr0. Any ideas on next steps are greatly appreciated!

  I'm running Ubuntu 14.04 on an old '08 macbook. I've gone to system settingsSoftware & UpdatesAdditional Drivers and enabled the wireless driver. But when I click the wifi icon on the top toolbar no networks show up. When running lshw it clearly shows my wireless card under Network controller and it says the driver is installed. However, nm-tool only shows ethernet. And rfkill only shows bluetooth. What can I do?

• Cisco AnyConnect VPN Client broke my internet

  - by user137864

  I was using the AnyConnect client when it froze and I had to do a hard reboot of my computer. Now I can't connect to the internet at all, with or without VPN. The Network Connections manager seems to think I have a wired and wireless connection without a problem, but I can't go online. I have tried using /etc/init.d/networking restart and it even says it is "ok" with no luck. I am guessing I need to clear some settings somewhere and restart a service, but I am not sure what. Thanks!

• 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.

• VMware server 2.0 SYN/ACK repeating issues

  - by user65579

  VMWare Server 2.0.0 Build 122956 I am having some issues with connecting into a guest VM (Ubuntu linux 4.4.3-4 lucid) running under VMware 2.0 on a windows server host. All connections to and from the VM's work fine, except for FTP. I thought the issue was the FTP daemon at first but it has been ruled out that it is not the daemon or the server itself. When you try to connect to the FTP server from outside of the host OS it fails with a "421 Service not available" but when you try and connect from the local VM or from the host OS the connection goes through fine. I have ran many packet sniffs using wireshark/tcpdump from the VM, the host OS, and the client connecting, the most informative is the host OS. I have attached a PNG of the relavant packets that were captured. I viewed some other network traffic that was sniffed (WWW specifically) and it seems to do the same syn/ack repeating but the user doesnt see any issues. I have disabled the firewall and the issues persisits, I have tried with specific allow rules to ensure the data is allowed and no changes. It appears like VMware attempts to do the ICMP redirect and it works, but then it vmware repeats the packets sent so you get 3 syn/ack's for every one syn from the client. Also VMWare appears to be attempting to establish an FTP connection between the HOST OS and the GUEST OS, because I see the second SYN sent from the HOST OS to the GUEST to initiate a new connection, and it get the appropriate SYN/ACK followed by an ACK, but the client never sees any of this from its end. EG. syn from client syn/ack from host OS to client syn/ack from guest OS to client syn/ack from host OS to client The same thing happens when the connection reset is attempted, RST's start being sent and repeated, the server responds with a valid header to continue the FTP handshake but the RST acknowledgement is allready issued and things are closed. I am not 100% if this is a bug in VMware or possibly a VMNetwork missconfiguration. Does anyone have any thoughts on where exactly the issue could be, things to try to verify or rule out? I have linked to a picture of the relevant packets sniffed from the host OS. http://img18.imageshack.us/img18/7789/vmwareftpconnection.jpg

• Alienware m15x (older model) BSOD investigation

  - by Crishu

  A frined of mine asked me to help him with an Alienware m15x laptop that had a little service history. It was bought in june 2008, serviced in january 2009 for a random fps drop problem, Alienware returned it saying nothing was wrong. The laptop still had hiccups, but after juggling a few drivers and settings, the fps drops weren't as noticeable. Eventually it died in Sept. 2009. It would not boot up locking itself on a white/gray screen. (i think it was overheating .. clocking in 100 degrees Celsius). So back to Alienware it went. They replaced the GPU and all was fine. Up until these blue screens started showing up. One other thing that was updated was the HDD and a Windows 7 reinstall, in August. From then on it seems to have started its BSOD. Could this be the culprit? Why? 0_o The original Windows was Vista but it was upgraded with a digital download/purchase of Windows 7 Home Premium and activated after installing windows. No errors on the old HDD, just on the latest installation. LE:Due note that now the old HDD is used to see if issues re-occur. So please, I am in need of someone who can interpret these windows dump files: Minidump I may have come to some conflicting conclusions. So if someone can clarify each dump/date and the probable cause/error it had; and a final conclusion or solution, we would be very grateful. Also please consult report for other system info I omitted: same link,code: XRWIVLWG If I missed something or if you have any other questions I'll be happy to answer them. Thank you. Good day.

• 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.

• 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.

• 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)?

• 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.
