  • java.net.SocketException: Connection reset; No available router to destination

    - by adejuanc
    Sometimes a Weblogic Server will be unreachable, there could be several reasons, the server is hang, down, and thus not responding to a ping, or it could be related to a network issue.A possible point of failure in the network layer are firewalls. You should contact your network team if you have following messages: java weblogic.Admin -adminurl t3://adminServer.mydomain.com:7777 -username admin -password lockdown PINGFailed to connect to t3://adminServer.mydomain.com:7777: Destination unreachable; nested exception is:java.net.SocketException: Connection reset; No available router to destination A possible work around for the ping command is to use the HTTP protocol, instead of the t3 protocol. To enable this you must configure WebLogic to do HTTP tunneling. To enable, access the administration console, click servers-> server you want to reach-> protocols -> http -> enable Tunneling. no restart is necessary. And then, following command will work: java weblogic.Admin -adminurl http://adminServer.mydomain.com:7777 -username igmadmin -password l0ckdown PING

  • Unable to enumerate USB device

    - by takeshin
    Hello, My syslog is constantly filled with messages like this: Oct 16 11:48:35 my-laptop kernel: [61470.980078] hub 1-0:1.0: unable to enumerate USB device on port 2 Oct 16 11:48:35 my-laptop kernel: [61471.192079] hub 3-0:1.0: unable to enumerate USB device on port 2 The only USB device I use is Microsoft Natural Wireless Laser Mouse 7000.

  • Actor based concurrency and cancellation

    - by Akash
    I'm reading about actor based concurrency and I appreciate the simplicity of actors sequentially processing messages on a single thread. However there is one scenario that doesn't seen possible. Suppose that actor A sends a message to actor B, who then performs some long running task and returns a completion message to actor A. How can actor A force actor B to cancel the long running task after it has started? If actor B is running the task in its message queue thread, it won't pick up the cancellation message until it had completed the task; if actor B runs the task in a background thread then it seems to be violating the principle of actors. Is there a common way that this scenario is handled with actors? Or does each actor language/framework take a different approach? Or is this not a suitable problem to tackle via actors?

  • Google SMTP relay sending limits

    - by Gavin
    I'm considering using Google Apps for email with my company domain and for sending emails to customers from my website using SMTP. On Google's website it says the following: Limits for registered Google Apps users A registered Google Apps user cannot relay messages to more than 2,000 recipients per day. Limits per domain Per-domain sending limits are determined by the number of users in your Google Apps account. There are two per-domain limits: The maximum number of recipients allowed per domain per day is approximately 130 times the number of users in your Google Apps account. The maximum number of recipients allowed per domain in a 10 minute window is approximately 9 times the number of users in your Google Apps account. Additionally, the maximum number of recipients allowed per domain per day for accounts not yet paid for during the first month of service is 100. If I'm a single user, with a single domain, then does that mean I can only email 130 people a day using SMTP? That limit seems low.

  • Ubuntu 12.10 automatic logout

    - by anthony
    I just had a new desktop constructed and installed ubuntu 12.10 which was successful for the most part but every time I open up some applications like thunderbird I get automatically logged out and all my windows are closed. System error messages also come up from time to time. Also I'm not sure if this helps but if I select the "Use system title bar and borders" in chromium I will also get logged out and from that point won't be able to use it without getting logged out in the future. If I click on particular links as well. If anyone has any tips on how I can isolate and fix the problem I would greatly appreciate it.

  • Login crash loop

    - by dawmail333
    After about the second/third batch of updates on a fresh install of Ubuntu 12.04, I end up getting stuck in an infinite login loop: I enter my password, screen goes black and shows me the end of the initialisation messages (including things like CUPS initialising), and then the greeter reappears. Kicker is, as I'm using gnome-shell, I just decided to uninstall LightDM, ubuntu-desktop and unity-greeter, using GDM as my manager, and the problem still happens in exactly the same manner. I'm lost even as to where to start looking - Xorg logs, LightDM logs (before I removed it), syslog and dmesg logs have held no unusual information at all. I have a TeX assignment due next week, and reinstalling Ubuntu every time I want to work on it is not going to work (nor is using TeX on Windows ;). Anything else I should try?

  • Fixing Mobility Radeon HD3650 driver in 12.04 LTS

    - by Kevin
    Okay, I know the subject has been discussed many times, but i dont find any of the instructions working. Most promising guide was here https://launchpad.net/~makson96/+archive/fglrx ive also tried https://help.ubuntu.com/community/BinaryDriverHowto/ATI because since the driver installation was written on other sites as well, this page included a "patch" file, but since im unaware how to patch installations, im out of luck. If i understand correctly, the patch should fix the driver and eliminate constant error messages. My system is 64bit 12.04 LTS and card is Mobility Radeon HD3650. Usual installation of the driver results in weird display resoulution (1100x something, while it should be 1440x900) and even 3d games did not work. Can anyone give me any more pointers? Much appreciated!

  • Upgrade failed, now impossible to restart

    - by Jean Claude Dispaux
    I have an Aspire One with Ubuntu, that I use only when traveling, i.e. seldom. Yesterday I tried to start it, it informed me that I had to install a new release of Ubuntu. The download went fine, then I left it for the night. In the morning I found error messages. I tried to restart, but nothing works any longer. The only backup I have is two USB keys made by the person who installed Ubuntu, that say Recovery Ubuntu 8 and Ubuntu 9.10 respectively. Right now I plugged the "8", selected F12 and instructed to boot from the USB key. It has been running for an hour, the screen still says ubuntu, the USB key flashes red. By the way, I have no precious data on this machine, I do not care about losing data. Please advise on what to do now. Thanks.

  • Anyone used Jenkins with Sparkle (the cocoa app update framework)?

    - by Amy Worrall
    Pushing new Sparkle releases of our internal apps is a pain. I have to make the build, make the release notes file, sign the .zip with the private key, and add a new entry to the appcast file tying everything together. I'd love it if Jenkins could help: use the commit messages for the release notes, and automatically do the rest of it. Should I be looking at writing a new Jenkins plugin, or using shell scripting, or is there something already that will do what I want? (A quick Google didn't find anything.) I'm new to Jenkins, and am still trying to get a feel for what it can do. Do any other maintainers of Cocoa apps have any tips?

  • Building a chat-like functionality in iOS

    - by Mani BAtra
    I was planning to implement a functionality wherein a user can send data to a friend of his, similar to sending messages in WhatsApp. This is how I broke down the problem : The user registers for the app. This equates to user info being stored on a dedicated server. With the phone number as the key identifier. The user selects the friend to send a message to and pushes the data. The receiver polls the server regularly and acknowledges that the data has been received. I did a little bit of research and am thinking of implementing this using the XMPP Framework for iOS. Any pointers as to is this the correct implementation or some advice in general?

  • Aren't there compilers better at telling the programmer what's wrong in a code ?

    - by jokoon
    I have worked a little while with the Microsoft compiler from Visual C++ but I worked a long time with G++, and I remember often having bad times understanding what was wrong in my code with the former. Beside binary code generation and optimisation, I think this is a very important feature of a C++ compiler: giving the programmer a clue that makes him understand as fast as possible what is wrong with his/her code. I can understand some programmers understand programming as some sort of "competition" to make less errors, but to me that's a counter productive opinion. I once tried Clang compiler for C from the LLVM thingie, I didn't use it for a long time, but I was impressed on how explicit and easy to understand the error messages were. What are your experiences, and how do you think this matters ? Some WIP of C++ Clang: http://clang.llvm.org/cxx_status.html

  • What are other ideologies to establish relationships between distinct users besides followers/following and friends?

    - by user784637
    Websites like myspace and facebook establish relationships between distinct users using the "friending" ideology, where one user sends a request to be accepted by another user in order for them to have the mutual permission to do stuff like post messages on each others walls. Less restrictive than the "friending" ideology, Twitter and instagram use the followers/following ideology where you can subscribe to the tweets or posts of another user without their permission. Less restrictive than the "followers/following" ideology, email and calling someone on the phone allows you to directly contact anyone. Are there other ideologies that have been successfully implemented either in social networking sites or other real world constructs to establish relations between users?

  • ejabberd starts slow and fails

    - by Michael Tanner
    I installed ejabberd and tried to set it up. On my server there are strict rules which allow only several services and denies everything else. I experienced starting problems with my iptables rules and found out that ejabberd works when I allow everything in the iptables and restore my rules afterwards. Then it also works for connecting, registering and else. What could be the problem in my rules? Attached here: http://fixee.org/paste/s5s744j/ Would be nice to get a correction straight on fixee if I made a mistake. Thanks in advance. Edit 1: In the log files there are no specific error messages during startup.

  • Creating an encrypted, web-based proxy

    - by Jason
    I have moved to Asia where my internet connection is censored and I'd like to check my messages from social sites which happen to be blocked. As virtually all proxy servers are blocked in this country, I've decided to attempt to roll my own encrypted proxy server. Please note, the key word here is encrypted—if the sniffer sees anything like f@c3b00k or w:k:p3d:ia travelling down the wire I'm had. I have a website hosted with GoDaddy (Windows with PHP 5.2 & IIS 7). Is there any way I can set up an encrypted proxy through this service? If so, how, and what open source tools are available to use?

  • /usr/share/apport/apport-gpu-error-intel.py Error

    - by gopherballs
    I was on Ubuntu 12.10 and ran the system updates and after the re-install, the system became unstable and kept prompting me with the message "System Issue" and this as the error per Ubuntu "/usr/share/apport/apport-gpu-error-intel.py". After I tried re-starting, the issue is still appearing and the system ultimately freezes (requiring a hard reset). I tried a clean install of 12.10 and the system works fine until the newest updates are applied...it then returns to the same messages. I then tried a clean install of 12.04 LTS and just like 12.10 it works until the latest updates are applied. On 12.04, I tried to use the previous kernel - going from 3.5.0-26 to 3.5.0-23 and the issue is still there. Currently, I'm sitting on 12.04 LTS clean install without doing the updates and the system is working. Does anyone have an idea how to fix this? Thanks.

  • A simple message room

    - by webbyJoe
    Can anyone recommend a simple message room (not chat room) which I can use for a private communication between my users. My idea: to grant some users (2-3 at the most) a specific privilege to talk privately in a message room. none of them would be administrator there. I need such features: - admin panel for adding users allowed to post messages in room - room invisible to anyone except users - filtering not-allowed words - Ajax-enabled so that replies appear immediately - other message room features I have a linux hosting so PHP message room would be the best option. I thought of using a forum for this, but it's too much work as a forum is public by nature and I need something private by nature. Any ideas? Thanks in advance.

  • Network does not connect at boot

    - by Daniel Svozil
    I am on Ubuntu 12.04, fresh install. When I boot a machine, the boot screen says Connecting to network, later it is changed to something like Did not connect, trying for another 60s. However, the network does not connect at the boot. But I can then log in without a network connection, and if I start a network manager service manually from the terminal (sudo service network-manager start), the network is connected without any problems. Please, does anybody know where the problem could be? I don't want to wait more than two minutes every computer restart :-). I am new to Ubuntu (and also to upstart) so I am a bit lost. There is no /var/log/messages, in dmesg I found this record, though it may not be related: init: network-interface (eth1) pre-start process (492) terminated with status 1 init: network-interface (eth1) post-stop process (548) terminated with status 1 Thanks Daniel

  • Where would a spam bot be located?

    I have a hosted website using a free hosting service, I received an email this afternoon saying that I have been suspended because my account has been compromised.

  • Frequent GUI pauses in Ubuntu 13.04 / Unity / Intel HD4000

    - by Simon
    I'm experiencing very frequent (and regular) GUI pauses on my system. Every 30 seconds (pretty much exactly) the GUI will freeze for maybe .25 to .5 seconds. The mouse stops moving, keys stop echoing and a stopwatch timer briefly pauses. I'm using the Intel Graphics driver available from: https://download.01.org/gfx/ubuntu/13.04/main I've looked in a few places and tried a few things for a solution: I've checked cron and anacron for scheduled processes. I've disabled background processes (eg mysql, postgres, apache) not that these were doing anything anyway I've checked the following posts and tried the suggestions there: Unity GUI pauses/freezes for less than a few seconds How to go about troubleshooting frequent system pauses I've watched the system using top and System Monitor and there are no spikes (or even blips) of cpu usage when the pauses occur. There are no obvious error messages in dmesg or syslog There is loads of free RAM (8GB+) and no swap usage If it helps it's a ZooStorm i5 laptop with a HD4000 GPU, 16GB Ram and an SSD. Any help / suggestions would be very gratefully received.

  • Book about tcp, http, named pipe, shared memory, wcf and other inter-process communication protocol

    - by Samuel
    Recently, I had to create a program to send messages between two winforms executable. I used a tool with simple built-in functionalities to prevent having to figure out all the ins and outs of this vast quantity of protocols that exist. But now, I'm ready to learn more about the internals difference between each of theses protocols. I googled a couple of them but it would be greatly appreciate to have a good reference book that gives me a clean idea of how each protocol works and what are the pros and cons in a couple of context. Here is a list of nice protocols that I found: Shared memory TCP List item Named Pipe File Mapping Mailslots MSMQ (Microsoft Queue Solution) WCF I know that all of these protocols are not specific to a language, it would be nice if example could be in .net. Thank you very much.
