  • Load Balancer sftp persistence when a server goes offline

    - by Cobra Kai Dojo
    Let's say we have the following scenario: We have two identical *nix servers using a shared filesystem. We connect through SFTP (not FTPS) to one of them to upload a file to the shared filesystem, the server goes offline and we get redirected to the second system which is still available. My question is, would there be any connection persistence or the user will have to relogin? I guess a relogin would be needed because the ssh sessions are not shared between the two systems... Thanks in advance :)

  • Load Balancing Rails on Apache 2.x

    - by revgum
    My situation is that I need to proxy traffic to the root of my web server to port 81 for IIS, and then any traffic to a sub-directory needs to be directed to the rails app. my-server.com/ - needs to proxy to port 81 my-server.com/myapp - needs to point to the rails app This seems to be working alright for the rails application but the images, javascripts, and stylesheets are not actually working (proxied). I've tried to fiddle with the proxypass lines but it still doesn't work for me..can anyone help? Here's my complete VirtualHost portion of the config; LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_http_module modules/mod_proxy_http.so ProxyRequests off <Proxy balancer://myapp_cluster> BalancerMember http://127.0.0.1:3001 BalancerMember http://127.0.0.1:3002 </Proxy> <VirtualHost *:80> DocumentRoot "c:\ruby\apps\myapp\public" <Directory /myapp > Options FollowSymLinks AllowOverride None </Directory> ProxyPass /myapp/images !

  • What is the recommended glusterFS configuration for a growing website?

    - by montana
    Hello, I have a website that is tracking towards 50 million hits per day average, and within the next 3 months should be over 100 million hits per day. We are trying to use GlusterFS v 3.0.0 (with latest patches as of 1-17-2010) Currently, we've just upgraded to a load balancer environment that has 3 physical hosts with 6 Xen-Server 5.5u1 VM's (2 on each host) to serve webpage traffic. Each machine has 6 Raid-6 local storage drives (7200RPM-SATA). The old machine we came from had 1 mirrored SAS 10k drive. We also set up glusterFS currently with 3 bricks, one on each host, and it is serving the 6 VM's as clients. In testing, everything seemed fine. However when we went to production, it seemed that there just wasn't enough I/O's available to serve traffic even upwards of 15mil hits. Weeks prior, our old server was able to handle traffic, maxed out, at 20mil. Is there any recommended configurations for such an application, or things to be aware of that isn't apparent with their documentation at gluster.org for a site our size?

  • Load balancing with Cisco router

    - by you8301083
    I have a Cisco router with two bonded T1's which are setup as a VPN to the main office. We need more bandwidth but can't get other connections (or it's too costly), so I would like to have a dsl connection installed. This DSL connection will run over a VPN to the same main office, but it won't be bonded with the T1's - so it won't act as a single connection. Since the three circuits won't act as a single connection (basically would be two connections 2 T1's + 1 DSL) we would have to split the network in half - but I don't want to do that. Instead, would it be possible to send all HTTP/HTTPS over the DSL connection but send all mission critical data (such as voice/active directory) over the T1's? I basically want to send specific ports over DSL and everything else over the T1's without separating half of the users traffic over the DSL and the rest over the T1's.

  • ARR servers in the Load Balancing pool automatically go from unavailable to available

    - by Chris
    I have 3 IIS web servers in an ARR web farm. When we do rolling releases, we take one server offline as a backup server and move it into an "Unavailable State" I have noticed that with ARR, servers will not stay in this state...they come back online automatically hours or days later. Does anyone know how to remedy this situation? This is very bad as the server that is down is typically not running the correct version of our code. I need to keep a server unavailable until i tell it otherwise.

  • Network load balancing, efficience and limits?

    - by Vimvq1987
    I'm about to study about NLB on Windows Server 2003. It archives both of my interests now: scalability and high-availability. But I don't know about its power in production environment. Is NLB a efficient solution? How does it implement in real-world? Is it popular? What are its limit? Thank you so much for answering my questions. :)

  • nginx automatic failover load balancing

    - by robinmag
    Hi, I'm using nginx and NginxHttpUpstreamModule for loadbalancing. My config is very simple: upstream lb { server 127.0.0.1:8081; server 127.0.0.1:8082; } server { listen 89; server_name localhost; location / { proxy_pass http://lb; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } But with this config, when one of 2 backend server is down, nginx still routes request to it and it results in timeout half of the time :( Is there any solution to make nginx to automatically route the request to another server when it detects a downed server. Thank you.

  • Troubleshooting web page load issues

    - by Richard Testani
    I having an odd issue where a particular page doesn't finish loading... all the time. Intermittenly, this page doesn't finish loading - in particluar, it seems maybe the JS file isn't downloaded or finished loading. Marchelos Law I am not sure how to troubleshoot this issue, since refreshing it fixes it. I see it mostly in IE 7 & 8, rarely in Safari or FireFox. If you view the page in question, refreshing it - you should see the issue. Any ideas?

  • Cycles/byte calculations

    - by matskn
    Hi ! In Crypto communities it is common to measure algorithm performance in cycles/byte. My question is, which parameters in the CPU architecture are affecting this number? Except the clockspeed ofcourse :)

  • Can Acrobat 11 be made to do OCR using multiple CPU cores?

    - by tarcman.
    OCR processing takes time. Using multiple CPU cores would speed up processing. Acrobat 10 was not a multithreaded application. How about Acrobat 11? Does 11 by default do OCR using multiple CPU cores (if available)? If not, are there any workarounds, e.g. scripting, to help make Acrobat 11 do OCR using multiple CPU cores? Either through Acrobat's built in scripting language or using external scripts that launch and direct multiple single thread instances of Acrobat to in parallell to parts of the processing job. Note: This question is not too localized (not limited to a specific moment in time) because (1) Adobe does not release new major Acrobat versions very often (Acrobat 10 was released two years ago) and (2) Adobe Acrobat is a widely used application.

  • How can I judge the suitability of modern processors for systems with specific CPU requirements?

    - by Iszi
    Inspired by this question: How do I calculate clock speed in multi-core processors? The answers in the above question do a fair job of explaining why a lower-speed multi-core processor won't necessarily perform at the same level as a higher-speed single-core processor. Example: 4*2=8, but a quad-core 2 GHz processor isn't necessarily as fast as a single-core 8 GHz processor. However, I'm having a hard time putting the information in those answers to practical use in my mind. Particularly, I want to know how it should be used to judge whether a given CPU is appropriate for an application with specific requirements. Example scenarios: An application has a minimum CPU requirement of 2.4 GHz dual-core. Another application has a minimum CPU requirement of 1.8 GHz single-core. For either of the above scenarios: Would a higher-speed processor with fewer cores, or a lower-speed processor with more cores, be equally sufficient? If so, how can we determine the appropriate processor speeds required for a given number of cores?

  • What is normal SCSI error handling process (scsi_eh_3) CPU time usage?

    - by Kris Jordan
    Last week I got setup with a new dedicated server that is running 4x SCSI drives in RAID 10 on CentOS. The machine is pretty lightly loaded at the moment and has been running for 8 days. The process 'scsi_eh_3' has a CPU time of 13:09.67 in top. This is 3x the next closest CPU time of 4:03.93 for mysqld. Is it normal for the scsi error handling process to use this much CPU time? (Seems like it goes to 0.3% usage ever 5 seconds.) Could this be an indicator that one or more of the drives is having issues?

  • What service can hold CPU at lowest frequency possible when on battery load under Ubuntu?

    - by vava
    When I'm running on battery even with "performance" frequency scaling governor, something regularly lowers CPU speed to it's lowest value. I don't really want that, my AC strip usually in another room so I don't really need to save power. How can I find what service doing that? laptop_mode is disabled so that's not it. Update: Looks like CPU being scaled down only if it is under load. If it is more or less idle, it could stay on any frequency pretty much forever, but once it gets loaded, it quickly jumps to it's lowest frequency. Another update: Something sets maximum frequency CPU can have. Ubuntu launchpad bug 242006

  • Why does my CPU Usage reach 100% too often?

    - by deathlock
    I'm using a dual-core processor and often see my CPU usage reaches 100%. I realize this may happen if I'm running too much applications, so when I know the computer starts to run slowly, I start to close my applications. I usually run 4-5 applications simultaneously. Usually those are: web browser (Google Chrome), Adobe Photoshop, Notepad++, XAMPP, and Windows Task Manager. Usually I close tabs in my Chrome first, because I often browse the net with about 20 tabs/4 windows open, so I presume that would take much memory (bad habit, I know). But even after closing Chrome's tabs or closing other applications, my CPU Usage often stays at high percentage - 72% at best, 100% at worst. I check the Processes tab on Windows Task Manager and usually found the System, System Idle Process, or services.exe taking the highest CPU process (could reach 60). Why is this happening? And is there any solution? EDIT I have T2250 @ 1,73 Ghz and 2.5 GB RAM

  • Any way to disable specific CPU idle (Cx) states?

    - by Philippe
    I just got a new Toshiba Tecra S11 notebook, which has a Core i5 520M CPU, and it appears to suffer from a well-known problem: a high pitched noise when the CPU is idle. Googling around revealed that this is caused by a specific power-saving mode in the CPU. In most cases, C4 mode is blamed for the noise. So my question is: is it possible to disable C4 mode (or any other "sleep" mode) using some utility or BIOS setting? I don't mind if it hurts battery life. I'd appreciate any advice on this matter. It's driving me crazy. FYI: I'm running Windows 7 64-bit

  • Biztalk Server 2009 - Failover Clustering and Network Load Balancing (NLB)

    - by FullOfQuestions
    Hi, We are planning a Biztalk 2009 set up in which we have 2 Biztalk Application Servers and 2 DB Servers (DB servers being in an Active/Passive Cluster). All servers are running Windows Server 2008 R2. As part of our application, we will have incoming traffic via the MSMQ, FILE and SOAP adapters. We also have a requirement for High-availability and Load-balancing. Let's say I create two different Biztalk Hosts and assign the FILE receive handler to the first one and the MSMQ receive handler to the second one. I now create two host instances for each of the two hosts (i.e. one for each of my two physical servers). After reviewing the Biztalk Documentation, this is what I know so far: For FILE (Receive), high-availablity and load-balancing will be achieved by Biztalk automatically because I set up a host instance on each of the two servers in the group. MSMQ (Receive) requires Biztalk Host Clustering to ensure high-availability (Host Clustering however requires Windows Failover Clustering to be set up as well). No loading-balancing option is clear here. SOAP (Receive) requires NLB to achieve Load-balancing and High-availability (if one server goes down, NLB will direct traffic to the other). This is where I'm completely puzzled and I desperately need your help: Is it possible to have a Windows Failover Cluster and NLB set up at the same time on the two application servers? If yes, then please tell me how. If no, then please explain to me how anyone is acheiving high-availability and load-balancing for MSMQ and SOAP when their underlying prerequisites are mutually exclusive! Your help is greatly appreciated, M

  • PF, load balanced gateways, and Squid

    - by Santa
    Hi, So I have a FreeBSD router running PF and Squid, and it has three network interfaces: two connected to upstream providers (em0 and em1 respectively), and one for LAN (re0) that we serve. There is some load balancing configured with PF. Basically, it routes all traffic to ports 1-1024 through one interface (em0) and everything else through the other (em1). Now, I have a Squid proxy also running on the box that transparently redirects any HTTP request from LAN to port 3128 in 127.0.0.1. Since Squid redirects this request to HTTP outside, it should follow the load balancing rule through em0, no? The problem is, when we tested it out (by browsing from a computer in the LAN to http://whatismyip.com, it reports the external IP of the em1 interface! When we turn Squid off, the external IP of em0 is reported, as expected. How do I make Squid behave with the load balancing rule that we have set up? Here's the related settings in /etc/pf.conf that I have: ext_if1="em1" # DSL ext_if2="em0" # T1 int_if="re0" ext_gw1="x.x.x.1" ext_gw2="y.y.y.1" int_addr="10.0.0.1" int_net="10.0.0.0/16" dsl_ports = "1024:65535" t1_ports = "1:1023" ... squid=3128 rdr on $int_if inet proto tcp from $int_net \ to any port 80 -> 127.0.0.1 port $squid pass in quick on $int_if route-to lo0 inet proto tcp \ from $int_net to 127.0.0.1 port $squid keep state ... # load balancing pass in on $int_if route-to ($ext_if1 $ext_gw1) \ proto tcp from $int_net to any port $dsl_ports keep state pass in on $int_if route-to ($ext_if1 $ext_gw1) \ proto udp from $int_net to any port $dsl_ports pass in on $int_if route-to ($ext_if2 $ext_gw2) \ proto tcp from $int_net to any port $t1_ports keep state pass in on $int_if route-to ($ext_if2 $ext_gw2) \ proto udp from $int_net to any port $t1_ports Thanks!

  • Load Spikes on a Apache MySQL Server with Wordpress MU

    - by Vikram Goyal
    Hi there, I am trying to investigate the reasons for some mysterious load spikes on a Linux Apache server (2.2.14) running PHP 5.2.9 on a dedicated server with enough processing power and memory. My primary web application is a Wordpress MU (2.9.2) installation. I have investigated and ruled out DOS attack, MySQL or Apache configuration issues. The log files don't give me anything of interest, except to tell me that there is severe load. The load (which can go up to 100) just seems to come and go. It helps that I have a script that checks every 3 minutes for the load, and restarts Apache. Restarting it helps, and the server comes back, till it happens again. There seems to be no set time frame, or visitor numbers on the site that can trigger this. Even a low number of concurrent visitors (20) can trigger it. I am almost convinced that there is a rewrite loop somewhere that is causing Apache to go mad. Apache is trying to serve something that is causing it to spawn more and more processes till it keels over. My question is: Given that I am convinced that this is a rewrite issue or something similar, how can I try and figure out what the issue is? What should I monitor? Apache logs are voluminous, and not very helpful. Of course, if this is not the issue, then at least knowing what to look for will help me eliminate this as an issue and look for something else. Thanks! Vikram

  • Calling function after .load (Jquery)

    Having a little difficulty getting a function to call after a .load: $(function(){ $('a.pageFetcher').click(function(){ $('#main').load($(this).attr('rel')); }); }); The page loads, but the functions don't fire: $(function(){ var $container = $('#container'); $container.imagesLoaded(function(){ $container.masonry({ itemSelector: '.box', }); }); $container.infinitescroll({ navSelector : '#page-nav', nextSelector : '#page-nav a', itemSelector : '.box', loading: { finishedMsg: 'Nothing else to load.', img: 'http://i.imgur.com/6RMhx.gif' } }, function( newElements ) { $.superbox.settings = { closeTxt: "Close this", loadTxt: "Loading your selection", nextTxt: "Next item", prevTxt: "Previous item" }; $.superbox(); var $newElems = $( newElements ).css({ opacity: 0 }); $newElems.imagesLoaded(function(){ $newElems.animate({ opacity: 1 }); $container.masonry( 'appended', $newElems, true ); }); } ); }); I've attempted to combine them so that the 2nd functions are called after .load (after doing some searching on this site and looking at given answers/examples) but nothing seems to work properly. Suggestions?
