  • Can not access Internet (DNS names do not resolve) after update today

    - by Aras
    I have been using Precise for a few weeks now for work with no problem. Today, I am not able to access any website using either wired or wireless connections. I installed the updates today which included nautilus, xserver, and a new kernel (3.2.0-24). After restarting I no longer was able to browse the Internet using firefox or chrome. Trying to ping google in terminal gives ping: unknown host google.ca I have tried: Connecting to wireless or wired networks (both working on other machines) Restart the machine and boot with previous Kernel Manually configure opendns on my wired connection Restart the network and the laptop and the wireless card Without any success so far. I am not sure where to go next. Please let me know the cause of the issue or help me troubleshoot it. Note that the laptop does receive an ip address, and it can ping ip address of google.ca (74.125.127.94) but not the domain name, or any domain name for that matter. This system was upgraded from 11.10 to 12.04 more two weeks ago.

  • Setting Connection Parameters via ADO for MSSQL

    - by taspeotis
    Is it possible to set a connection parameter on a connection to SQL Server and have that variable persist throughout the life of the connection? The parameter must be usable by subsequent queries. We have some old Access reports that use a handful of VBScript functions in the SQL queries (let's call them GetStartDate and GetEndDate) that return global variables. Our application would set these before invoking the query and then the queries can return information between date ranges specified in our application. We are looking at changing to a ReportViewer control running in local mode, but I don't see any convenient way to use these custom functions in straight T-SQL. I have two concept solutions (not tested yet), but I would like to know if there is a better way. Below is some psuedo code. Set all variables before running Recordset.OpenForward Connection->Execute("SET @GetStartDate = ..."); Connection->Execute("SET @GetEndDate = ..."); // Repeat for all parameters Will these variables persist to later calls of Recordset->OpenForward? Can anything reset the variables aside from another SET/SELECT @variable statement? Create an ADOCommand "factory" that automatically adds parameters to each ADOCommand object I will use to execute SQL // Command has been previously been created ADOParameter *Parameter1 = Command->CreateParameter("GetStartDate"); ADOParameter *Parameter2 = Command->CreateParameter("GetEndDate"); // Set values and attach etc... What I would like to know if there is something like: Connection->SetParameter("GetStartDate", "20090101"); Connection->SetParameter("GetEndDate", 20100101"); And these will persist for the lifetime of the connection, and the SQL can do something like @GetStartDate to access them. This may be exactly solution #1, if the variables persist throughout the lifetime of the connection.

  • Java: Clearing up the confusion on what causes a connection reset

    - by Zombies
    There seems to be some confusion as well contradicting statements on various SO answers: http://stackoverflow.com/questions/585599/whats-causing-my-java-net-socketexception-connection-reset . You can see here that the accepted answer states that the connection was closed by other side. But this is not true, closing a connection doesn't cause a connection reset. It is cauesed by "an underlying TCP/IP error." What I want to know is if a SocketException: Connection reset means really besides "unerlying TCP/IP Error." What really causes this? As I doubt it has anything to do with the connection being closed (since closing a connection isn't an exception worthy flag, and reading from a closed connection is, but that isn't an "underlying TCP/IP error." My hypothesis is this Connection reset is caused from a server's failure to acknowledge an ACK packet (either wholly or just improperly as per TCP/IP). And that a SocketTimeoutException is generated only when no data is generated to be read (since this is thrown during a read after a certain duration, and read is waiting for data, but is not concerned with ACK packets). In other words, read() throws SocketTimeoutException if it didn't read any bytes of actual data (DATA LAYER) in its allotted time.

  • Can't connect nonlocally after 12.10 upgrade

    - by user101815
    I've just upgraded one of my systems from 12.04 to 12.10. Now I can't connect on that system beyond my local network. Connections within the local network seem to work fine, and I can make nonlocal connections from other machines (like the one I'm asking this question from). I suspect that some routing information has been messed up, but I don't know where to look for it. It's not a nameserver problem -- pinging outside sites by their IP addresses doesn't work either. I have another laptop next to this one, also running Kubuntu 12.10. On the one that can't connect, arp produces no output. On the other one, it produces 192.168.0.1 ether 00:23:69:fa:ce:ae C wlan0 On the working machine, the output of netstat starts with some tcp entries. On the nonworking one, those entries are absent. I asked this question on the Ubuntu forum but haven't gotten any answers there. One further complication: since the troublesome machine has no outside connection, it's extremely difficult to download anything to it. For what it's worth, "ping 8.8.8.8" produces "connect: Network is unreachable". Update: after a lot of fiddling, I have my external world back. I don't know what the key action was, but the first indication of progress was that "ping 8.8.8.8" worked. At that point I still didn't have a working nameserver, so external URLs didn't work. But I did this (based on an online post, of course): sudo dpkg-reconfigure resolvconf and answered Yes to all prompts. That did the trick!! Apparently my problem was unique, or close to it, since I couldn't find any online references to it: local net working, remote net not working, including explicit IP addresses. So I suppose that if no one else has this problem, no one cares about the solution!!

  • weird SSH connection timed out

    - by bran
    This problem started when I tried to login to my brand spaning new VPS server. I remember that in my first SSH try on the server I actually got prompt for password several times which would mean that there is no port blocking problem from my isp. Since the password did'nt work for me (for some reason). I had a lot of authentication failure. After that attempting to log in to the server just timed out. I did the same at mediatemple (which used to work before with sftp) and put in wrong password and now trying to ssh (or even SFTP) gives me timeout error. So some kind of security feature is preventing me from trying too many times to log in, either from my side or from the server side. Any idea what it could be? TRaceroute and ping works on the ips. I am using a zyxel wimax modem (max-206m1r - if that's relevent) c:\Program Files (x86)\OpenSSH\bin>ssh.exe [email protected] ssh: connect to host 109.169.7.136 port 22: Connection timed out c:\Program Files (x86)\OpenSSH\bin>ssh.exe [email protected] ssh: connect to host 109.169.7.131 port 22: Connection timed out c:\Program Files (x86)\OpenSSH\bin>ssh.exe [email protected] ssh: connect to host 87.117.249.227 port 22: Connection timed out c:\Program Files (x86)\OpenSSH\bin>ssh.exe [email protected] -vv OpenSSH_5.6p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Reading configuration data /etc/ssh_config debug2: ssh_connect: needpriv 0 debug1: Connecting to 87.117.249.227 [87.117.249.227] port 22. debug1: connect to address 87.117.249.227 port 22: Connection timed out ssh: connect to host 87.117.249.227 port 22: Connection timed out c:\Program Files (x86)\OpenSSH\bin>ssh.exe s122797.gridserver.com Could not create directory '/home/pavs/.ssh'.

  • Slow wired internet connection on Realtek RTL8168-8111 (Rev 6)

    - by Mark
    I keep on seeing issues people are having with their wireless. I am having an issue with being wired into my router. I installed Ubuntu 11.10 the other day, on my custom PC. The motherboard I have installed on this PC is an ASUS P8H61-M. The issue I am having is with my speed. I have a dual boot, windows 7 and the new Ubuntu. On my Windows install I am getting test speeds from Speakeasy at 17Mbps and actual downloads around 2-3MB/s. With Ubuntu, I am getting test speeds from Speakeasy at 1.14Mbps and actual downloads around 60KB/s. I have disabled IPv6 and am no using GoogleDNS for my DNS, but it hasn't resolved the issue. I have scanned my router (WRT54GS Linksys) to disable IPv6 connections, and I am not seeing any option for that. I cannot figure out why I am getting such sluggish internet connection. Any help to resolve would be great!

  • Rails Resque workers fail with PGError: server closed the connection unexpectedly

    - by gc
    I have site running rails application and resque workers running in production mode, on Ubuntu 9.10, Rails 2.3.4, ruby-ee 2010.01, PostgreSQL 8.4.2 Workers constantly raised errors: PGError: server closed the connection unexpectedly. My best guess is that master resque process establishes connection to db (e.g. authlogic does that when use User.acts_as_authentic), while loading rails app classes, and that connection becomes corrupted in fork()ed process (on exit?), so next forked children get kind of broken global ActiveRecord::Base.connection I could reproduce very similar behaviour with this sample code imitating fork/processing in resque worker. (AFAIK, users of libpq recommended to recreate connections in forked process anyway, otherwise it's not safe ) But, the odd thing is that when I use pgbouncer or pgpool-II instead of direct pgsql connection, such errors do not appear. So, the question is where and how should I dig to find out why it is broken for plain connection and is working with connection pools? Or reasonable workaround?

  • .NET socket timeout - blocking on Close method

    - by Mark
    I'm having trouble implementing a connect timeout using asynchronous socket calls. The idea being that I call BeginConnect on a Socket object, then use a timer to call Close() on the socket after a timeout period has elapsed. This works fine as long as the socket is created on the GUI thread - the Close method returns immediately, and the callback method is executed. However, if the socket is created on any other thread, the Close method blocks until the default IP timeout occurs. Code to reproduce: private Socket client; private void button1_Click(object sender, EventArgs e) { // Creating the socket on a threadpool thread causes Close to block. ThreadPool.QueueUserWorkItem((object state) => { client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IAsyncResult result = client.BeginConnect(IPAddress.Parse("144.1.1.1"), 23, new AsyncCallback(CallbackMethod), client); // Wait for 2 seconds before closing the socket. if (result.AsyncWaitHandle.WaitOne(2000)) { MessageBox.Show("Connected."); } else { MessageBox.Show("Timed out. Closing socket..."); client.Close(); MessageBox.Show("Socket closed."); } }); } private void CallbackMethod(IAsyncResult result) { MessageBox.Show("Callback started."); Socket client = result.AsyncState as Socket; try { client.EndConnect(result); } catch (ObjectDisposedException) { } MessageBox.Show("Callback finished."); } If you remove the QueueUserWorkItem line, creating the socket on the GUI thread, the socket closes instantly without blocking. Can anyone shed some light on what's going on? Thanks. Edit - System.Net trace output seems to be different depending on whether it's being connected on the GUI thread or a different thread: Trace from non-blocking close when using GUI thread Trace from blocking close when using non-GUI thread

  • Timer Service in ejb 3.1 - schedule calling timeout problem

    - by Greg
    Hi Guys, I have created simple example with @Singleton, @Schedule and @Timeout annotations to try if they would solve my problem. The scenario is this: EJB calls 'check' function every 5 secconds, and if certain conditions are met it will create single action timer that would invoke some long running process in asynchronous fashion. (it's sort of queue implementation type of thing). It then continues to check, but as long as long running process is there it won't start another one. Below is the code I came up with, but this solution does not work, because it looks like asynchronous call I'm making is in fact blocking my @Schedule method. @Singleton @Startup public class GenerationQueue { private Logger logger = Logger.getLogger(GenerationQueue.class.getName()); private List<String> queue = new ArrayList<String>(); private boolean available = true; @Resource TimerService timerService; @Schedule(persistent=true, minute="*", second="*/5", hour="*") public void checkQueueState() { logger.log(Level.INFO,"Queue state check: "+available+" size: "+queue.size()+", "+new Date()); if (available) { timerService.createSingleActionTimer(new Date(), new TimerConfig(null, false)); } } @Timeout private void generateReport(Timer timer) { logger.info("!!--timeout invoked here "+new Date()); available = false; try { Thread.sleep(1000*60*2); // something that lasts for a bit } catch (Exception e) {} available = true; logger.info("New report generation complete"); } What am I missing here or should I try different aproach? Any ideas most welcome :) Testing with Glassfish 3.0.1 latest build - forgot to mention

  • socket timeout and remove O_NONBLOCK option

    - by juxstapose
    Hello, I implemented a socket timeout and retry but in order to do it I had to set the socket as a non-blocking socket. However, I need the socket to block. This was my attempt at a solution to these two problems. This is not working. Subsequent send calls block but never send any data. When I connect without the select and the timeout, subsequent send calls work normally. References: C: socket connection timeout How to reset a socket back to blocking mode (after I set it to nonblocking mode)? Code: fd_set fdset; struct timeval tv; fcntl(dsock, F_SETFL, O_NONBLOCK); tv.tv_sec = theDeviceTimeout; tv.tv_usec = 0; int retries=0; logi(theLogOutput, LOG_INFO, "connecting to device socket num retrys: %i", theDeviceRetry); for(retries=0;retries<theDeviceRetry;retries++) { connect(dsock, (struct sockaddr *)&daddr, sizeof daddr); FD_ZERO(&fdset); FD_SET(dsock, &fdset); if (select(dsock + 1, NULL, &fdset, NULL, &tv) == 1) { int so_error; socklen_t slen = sizeof so_error; getsockopt(dsock, SOL_SOCKET, SO_ERROR, &so_error, &slen); if (so_error == 0) { logi(theLogOutput, LOG_INFO, "connected to socket on port %i on %s", theDevicePort, theDeviceIP); break; } else { logi(theLogOutput, LOG_WARN, "connect to %i failed on ip %s because %s retries %i", theDevicePort, theDeviceIP, strerror(errno), retries); logi(theLogOutput, LOG_WARN, "failed to connect to device %s", strerror(errno)); logi(theLogOutput, LOG_WARN, "error: %i %s", so_error, strerror(so_error)); continue; } } } int opts; opts = fcntl(dsock,F_GETFL); logi(theLogOutput, LOG_DEBUG, "clearing nonblock option %i retries %i", opts, retries); opts ^= O_NONBLOCK; fcntl(dsock, F_SETFL, opts);

  • Connection Pooling

    - by cshah
    I have the following code, If I use conn == null in finally do I still use connection pooling? I know it is a good practice to close your connection but how about disposing the whole connection object? public void ExecuteNonQuery(SqlCommand Cmd) { //========== Connection ==========// SqlConnection Conn = new SqlConnection(strConStr); try { //========== Open Connection ==========// Conn.Open(); //========== Execute Command ==========// Cmd.Connection = Conn; Cmd.CommandTimeout = 180; Cmd.ExecuteNonQuery(); } catch (Exception Exc) { throw Exc; } finally { //======== Closing Connection ========// if (Conn.State == ConnectionState.Open) { Conn.Close(); } //======== Disposing object ========// Conn = null; } }

  • Apachebench on node.js server returning "apr_poll: The timeout specified has expired (70007)" after ~30 requests

    - by Scott
    I just started working with node.js and doing some experimental load testing with ab is returning an error at around 30 requests or so. I've found other pages showing a lot better concurrency numbers than I am such as: http://zgadzaj.com/benchmarking-nodejs-basic-performance-tests-against-apache-php Are there some critical server configuration settings that need done to achieve those numbers? I've watched memory on top and I still see a decent amount of free memory while running ab, watched mongostat as well and not seeing anything that looks suspicious. The command I'm running, and the error is: ab -k -n 100 -c 10 postrockandbeyond.com/ This is ApacheBench, Version 2.0.41-dev <$Revision: 1.121.2.12 $> apache-2.0 Copyright (c) 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Copyright (c) 2006 The Apache Software Foundation, http://www.apache.org/ Benchmarking postrockandbeyond.com (be patient)...apr_poll: The timeout specified has expired (70007) Total of 32 requests completed Does anyone have any suggestions on things I should look in to that may be causing this? I'm running it on osx lion, but have also run the same command on the server with the same results. EDIT: I eventually solved this issue. I was using a TTAPI, which was connecting to turntable.fm through websockets. On the homepage, I was connecting on every request. So what was happening was that after a certain number of connections, everything would fall apart. If you're running into the same issue, check out whether you are hitting external services each request.

  • Dell Perc 6i with FreeBSD 8.1 errors with mfi0: COMMAND xxxxxxxx TIMEOUT AFTER xxx SECONDS

    - by jDempster
    We've recently bought two Dell PowerEdge R710 servers with Perc 6i controllers and 6x 135GB SAS Drives. We'd done some pretty extensive testing on a Dell PowerEdge R510 server with a Perc 6i and 4x 135GB SAS Drives running FreeBSD 8.1 for it's wonderful ZFS support and mfiutil. We hadn't had any problems with the R510 and had got to a point where we where happy with the performance of ZFS. Since running FreeBSD 8.1 on the R710 we've been getting errors from the RAID controller. mfi0: COMMAND 0xffffff80005d1770 TIMEOUT AFTER 6178 SECONDS This usually brings the system to a stand still. But it doesn't always happen, and performs very well up until it does happen. We've been running the disk as 3 mirrored drives striped in ZFS. So far we've noticed that running the drives with RAID10 on the RAID seems to work without errors (still testing). At first I thought hardware error as we'd been running FreeBSD on the R510 with the same controller without any issues. But both R710 have the same issue. All controllers are running the same firmware.

  • Puppet Agent fails sporadically, with either timeout or "Could not find class" error

    - by smokris
    I have puppet master running on a Xen dom0, and 3 domUs syncing to it via an hourly crontab puppet agent --test. About 80% of the time, the puppet agent --test completes successfully: info: Retrieving plugin info: Caching catalog for test3 info: Applying configuration version '1333319732' notice: Finished catalog run in 5.08 seconds The other 20% of the time, it fails midway, with errors such as the following: err: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find class iptables for test1 at /etc/puppet/manifests/site.pp:1 on node test1 warning: Not using cache on failed catalog err: Could not retrieve catalog; skipping run or info: Retrieving plugin info: Caching catalog for test2 info: Applying configuration version '1333319732' notice: Finished catalog run in 24.73 seconds err: Could not send report: Error 500 on SERVER: Internal Server Error private method `gsub' called for WEBrick::HTTPStatus::RequestTimeout:Class WEBrick/1.3.1 (Ruby/1.8.5/2006-08-25) OpenSSL/0.9.8e-rhel5 at puppet:8140 or info: Retrieving plugin err: Could not retrieve catalog from remote server: execution expired warning: Not using cache on failed catalog err: Could not retrieve catalog; skipping run or info: Retrieving plugin info: Caching catalog for test3 info: Applying configuration version '1333319732' notice: Finished catalog run in 9.47 seconds err: Could not send report: Error 408 on SERVER: Request Timeout During this time, I've not made any changes to the Puppet configuration — it just sporadically fails.

  • SqlCmd : Login timeout expired from localhost

    - by mschr
    I've setup the instance SQLEXPRESS via SQL Server 2008 R2 installation, added a security login with all server roles, one called 'sqluser'. The server authentication is SQL Server and Windows Authentication mode. However, when i specify the -S property, login fails. There is no firewall enabled and SQL server even accepts connections from remote hosts. C:\Users\user>sqlcmd -U sqluser -P qwerty -Q "Select * FROM testdb.dbo.testtable" Output: integer ------- 1 2 3 4 (4 rows affected) However when specifying 'localhost' the query fails... Question is Why? C:\Users\user>sqlcmd -S localhost/sqlexpress -U cpt -P 1234 -Q "Select * FROM cpt.dbo.testme" Output: HResult 0x43, Level 16, State 1 Named Pipes Provider: Could not open a connection to SQL Server [67]. Sqlcmd: Error: Microsoft SQL Server Native Client 10.0 : A network-related or in stance-specific error ..... Sqlcmd: Error: Microsoft SQL Server Native Client 10.0 : Login timeout expired. Changing 'localhost' with '%COMPUTERNAME' is same result if someone would be wondering. The server is running as a LocalSystem instance.

  • Network connection delay after installing indicator-network

    - by Adrian
    Ok, so here's the thing,I installed wingpanel in UBUNTU 10.10, i removed the gnome-panels (yes, both). In the wingpanel itself there's no NETWORK indicator, so i google it and in some forums, some guy wrote that you have to install "indicator-network". I did it, and it solved the network indicator in the wingpanel, BUT now everytime i turn on my computer, the connection takes like 2 minutes or more to connect, when before installing this thing it did it immediately. How can i solve this? any help?
