• Common filesystem for servers behind a rackspace load balancer

  - by thanos panousis

  Our PHP application consists of a single web server that will receive files from clients and perform a CPU-intensive analysis on them. Right now, analysis of a single user upload can take 3sec to conclude and take 100% CPU. This makes our system capacity amount to 1/3 requests per second. My team's requirement is to increase capacity without a lot of code reengineering. A possible solution would be to set up a load balancer in front of multiple servers running the same app, connecting to a common DB. The problem is that the analysis outputs files on disk. A load balancer would increase capacity, but then files won't be available between servers so consequent client requests may fail. We are hosted on Rackspace, is there a way to configure some sort of "common" storage for all servers, without having to rewrite our file persistance code? Current code relies on simple fopens etc. What are our options?

• How to disable Spotlight content indexing in Mac OS

  - by o.v.

  From Windows experience, I could always elect Live search to only index file names not their content. Is this something that can be done with Spotlight on a Mac? It used to index absolutely everything, for instance it would return a bunch of video files for any obscure character combination typed into the search field. Right now I've disabled Spotlight entirely as per this answer, but it seems to have disabled searching altogether. For instance, Finder is yet to locate any .pdf files in a small directory as I'm typing this question (unlike windows search which would still be able to work even with indexing disabled) Alternatively, if there is any way (including a trusted third-party app) that will index file names and metadata e.g. ID3 tags that would likely be the preferred option.

• Are there any tools for monitoring individual Apache virtual hosts in real-time?

  - by Dave Forgac

  I'm looking for a way to monitor and record Apache traffic, separated by virtual host. I am currently using Munin to capture this and other data for the entire server however I can't seem to find a way to do this by vhost. This link describes using a module called mod_watch which is apparently no longer in development: http://www.freshnet.org/wordpress/2007/03/08/monitoring-apaches-virtualhost-with-munin/ The file that is listed as being compatible with Apache 2.x is reported to have problems with missing vhosts an reporting data correctly. Does anyone know of a reliable way to determine real-time traffic per vhost? If I can find this it should be easy enough to write a new Munin plugin.

• How to determine what program send the packet recorded in Wireshark?

  - by Tono Nam

  I was taking some tutorials on Wireshark in order to analyze the packets sent and received when talking to a web server for purposes of learning. When I start listening/recording packets in Wireshark, there where so many packages being recorded (700 packages per minute). Is it normal to have that much traffic if I have all the programs that will cause traffic such as all browsers, log me in, dropbox, goto meeting, etc., closed? In order to try to solve the problem I am analyzing random packets. Take for instance this filter: I just selected a random IP: 74.125.130.99. So how can I know from what program those packets where created? Also how can I get more info about that communication bwtween my computer (192.168.0.139) and that server (74.125.130.99)? I just selected a random IP from the Wireshark capture. There are also other IPs that I have no idea why they are communicating with my computer. How can I figure that out?

• Post raid5 setup reboot shows single hard drive failure on ubuntu 12.10?

  - by junkie

  I just set up raid 5 on linux using three HDDs as per a guide. It all went fine until when I rebooted I got the following text: http://i.stack.imgur.com/Zsfjk.jpg. Does this mean one of my HDDs has failed? How do I check if any of them are failing? I tried using smartctl and didn't see any issues. Or is it nothing to do with failure and something else altogether? I would like to get the raid 5 working again but I'm not sure where to go from here. I'm using ubuntu 12.10 and the three raid disks each have a gpt partition with a single full size partition of filesystem type ext4. Note I only got an error on reboot not while I was creating the raid array which went fine. Thanks.

• Preventing my postfix to send my local users spam

  - by Jack

  I have a postfix/dovecot mail server with 100 different users. When they send an email they need to be authenticated. I successfully use saslauth to achieve this. Few days ago I had a problem. One specific user, probably with a virus or a spam-bot installed in its computer, started to send out through my server thousands of emails in few hours. As result, my ip has been blocked by many isp provider (@aol, @yahoo, and others) and has been listed in many blacklist, making all my 100 users unable to send any email to anyone. What is the best practice to avoid this problem? It would be great if my server could recognize a spamming user and automatically block it. Also, have a limit of, say, 30 emails per hour could be a partial solution. Any idea how to face this problem? Thank you

• Extracting a line section of mysql backup using sed

  - by carpii

  I occasionally need to extract a single record from a mysqlbackup To do this, I first extract the single table I want from the backup... sed -n -e '/CREATE TABLE.*usertext/,/CREATE TABLE/p' 20120930_backup.sql > table.sql In table.sql, the records are batched using extended inserts (with maybe 100 records per insert before it creates a new line starting with INSERT INTO), so they look like... INSERT INTO usertext VALUES (1, field2 etc), (2, field2 etc), INSERT INTO usertext VALUES (101, field2 etc), (102, field2 etc), ... Im trying to extract record 239560 from this, using... sed -n -e '/(239560.*/,/)/p' table.sql > record.sql Ie.. start streaming when it finds 239560, and stop when it hits the closing bracket But this isnt working as I hoped, it just results in the full insert batch being output. Please can someone give me some pointers as to where Im going wrong? Would I be better off using awk for extracting segments of lines, and use sed for extracting lines within a file?

• Mac OS 10.7 DMG files don't pop up anymore?

  - by Sosukodo

  Has anybody noticed that double-clicking on a DMG file no longer raises the mounted image to the front of all windows? It used to be that when you double-clicked a dmg file, it would pop-up but now you have to click Finder and click on the mounted image. Is this a bug, by design or a setting that I can change? Update: As per Daniel Beck's suggestion, I created a new account and downloaded the most recent version of Firefox via Safari. It still exhibited the same behavior. However, I noticed that if I double-click thew DMG from within the Downloads folder in Finder, it does pop up. But when I double-click the DMG within Safari (and Firefox also) it does not pop up over all other windows.

• Server downtime - are these APC warnings the cause?

  - by DisgruntledGoat

  Yesterday I had a problem with my dedicated server (Ubuntu 10.04, LAMP). It wasn't down per se, but running incredibly slowly as if we had a massive overload of visitors (though I don't think we did). It's running smoothly again now. I've been checking through log files etc to see if I can find any issues, the only strange thing is a bunch of these errors, occurring at about the same time as the downtime: [apc-warning] Unable to allocate memory for pool. in [file] on line 49. And a bit later on: [apc-warning] GC cache entry '[file1]' (dev=2056 ino=8988092) was on gc-list for 3601 seconds in [file2] on line 746. Could these errors indicate the cause of the server slowdown, or are they simply a result of the server being slow in the first place? What would be the solution?

• Remote desktop Client versus Web based access to reports and limited data entry

  - by Voyager

  We have a requirement from management to give limited access of our Application to Distributors \ Dealers to look at their account statements in our books of account, enter their purchase requirements (sales order for us). We have given a few of them the RDC who connect to our terminal server and access the reports. This involves licensing of TS Client per each distributor. Is it more better, secure and less costly if a web based application is made to only enter the orders and retrive reports like pending orders, ledgers, receivables etc. Also which is more secure as far as database access is concerened...browser based access or RDC access. Please answer.

• File Transfer Protocol (FTP) Service won't install

  - by user64204

  Hi all, Problem description: -I'm running Windows Server 2003 and I'm trying to install the FTP service following this procedure: http://support.microsoft.com/kb/323384 -At step 7 of the above procedure I provide Windows Small Business Server 2003 disc1 and the installation completes successfully (note: the installer looks for 'ftpctrs2.dll' but the disk contains 'FTPCTRS2.DL_' and seems happy with it as per allowed file types). -However the installation silently fails because if I go back to the list of windows components, FTP is still unchecked, and if I open IIS, the FTP sites section is missing. Question: -How can I force the installation of FTP? Additional info: I don't think this is related but will mention it in case I'm wrong and it is: before I could attempt to install FTP I ran into, and fixed, the issue described in this solution: http://support.microsoft.com/kb/838860 Thanks.

• sendmail new mail notification to external address only with the first unread email

  - by elcodedocle

  I'm running a webserver with a contact form which triggers a php script to sendmail the message to a local account on the server, and I want to be notified on my regular email account when I got new messages. I could have a notification per email or just send the emails directly to my account but that'd be too much: I just want a "you have new mail" notification sent to my email every time the inbox turns from 0 unread messages to 1. Google is burying me in sendmail documentation, and still can't find anything about it. Any ideas?

• What is the formula for HughesNet FAP calculation?

  - by JohnFx

  I am somewhat frustrated with the only FAP monitor I have found on the net and discovered because it relies on a running count of bandwidth usage which (1) requires a service in the background; and (2) Tends to get inaccurate over time. Given that there is a diagnostics page on the firmware of the modem that tells the exact usage per hour, I was planning on writing a more accurate version with a better UI. However, it appears that HughesNet keeps the exact formula for calculating whether you are in FAP a secret. I have no idea why they wouldn't be more forthcoming with this information. Wondering if anyone out in SU-land had done some trial and error testing to reverse engineer the formula or had some inside knowledge to share.

• Block Domain User login

  - by Param

  I have created a Domain User id ( for example - Auser ). I have integrated my LDAP login with Firewall. I use this user to login in to firewall only. So, I want to block all the login for this User except on Firewall. Is there any way to accomplish this? As per my knowledge, we can specify :- By right click on Domain User -- Properties -- Account tab -- Logonto ( but here we have to specify Computer Name, we don't have any computer name for Firewall -- So i can't use this option ) Through Group Policy Window Setting -- Security Setting -- Local Policies -- User Rights Assignment -- Allow logon Locally (But it has to apply on Computer OU -- So i can't use this option also ) Any Other Option you know ??

• Should I run my own MTA?

  - by Mascarpone

  I need to send a large volume of emails, roughly 60.000 per week. At the moment we outsource this service to a third party, and we expect to double our volume within the next 6 months. Since the service is starting to be too expensive, I was thinking about setting up our own MTA. Our own SysAdmin told us it is not difficult at all to have our own MTA, but I'm afraid he might have oversimplified this. Is it difficult to handle a MTA? Should I be afraid that my MTA will lose the company mails? Should I stay with a third party service? p.s: The emails have been collected respecting the local legislation on privacy, so no spam.

• How does a winkydink Teradici offer high res, full FPS, 3D rendering on ESXi 5 VDIs for AutoCAD/SolidWorks/1080p YouTube applications?

  - by BlueToast

  How does such a small Teradici card ![enter image description here][1] offer high resolution, full FPS 3D graphics (1:38) http://www.youtube.com/watch?v=eXA4QMmfY5Y&feature=player_detailpage#t=97s for ESXi 5.0/5.1 VDI environments? We're shooting for an AutoCAD/SolidWorks/YouTube 1080p capable environment. I can't see how such a small and low profile card could possibly have the horsepower to handle such GPU computations for a big environment like that. We're going to have up to 64 VDIs per server, and are a 500-1000 employee count sized company. Someone enlighten me please! Determining which route to go (between RemoteFX and VMware View/PCoIP) and the hardware (NVIDIA 4GB non-Quadro/Tesla GPUs vs Teradici card). Servers have three 4x, three 8x, and one 16x PCI-E lane. Two of the 8x lanes will be occupied by SAS RAID cards.

• Both screens always stay on after adding second monitor

  - by J.Merrill

  I had a single 1920x1080 monitor on a Windows 7 desktop PC and, per "power management" (not screen saver), the screen would go blank after 10 minutes. I added another monitor (2560x1600 if that matters) and since then, neither screen has ever blanked. I've tried turning on the "blank" screen saver, but that didn't help either -- I can go away for hours and when I come back, both screens are on. I've seen others with similar issues apparently caused by e.g. wireless mice that seem to move infinitesimally, but I've got the same wired mouse I had before. I can't understand why neither the screen saver nor power management is doing what it should to blank the screens, when "power management" used to do it when there was only one monitor. Maybe it doesn't matter so much with current LCD display technology (no "burn in") but doesn't a monitor use more power when "power management" hasn't turned off the display? Thanks for any suggestions.

• How can I migrate mails from Yahoo! Mail to Google Apps?

  - by alnorth29

  We'd like to move from using Yahoo! Mail to our Google Apps account. It'd be great to be able to migrate all the mails across from the old accounts to the new. If we were using Gmail accounts this would be easy as the migration is offered by Google, for some reason they don't offer this to those using custom domains. As far as I know Yahoo! don't offer POP or IMAP access to non-paying customers and I'd rather not pay $20 per account that I want to migrate. Anyone know of any easy and cheap solutions?

• Synckolab will not start automatically

  - by EBV2010

  We have a Kolab server for e-mail, calendar and contacts with Thunderbird for a client. The add-ons are Lightning and Synckolab. The workstations are Kubuntu, most 10.04, some 11.10. It basically works but for one nagging problem: the automatic sync (that is, the settings that starts Synckolab upon start of Thunderbird and every x minutes as per setting) does not fire. We went through the whole routine: setting it, setting it to zero and back to any number of minutes, stopping/starting Thunderbird or the entire computer to make sure it sees and sets it. In the configuration console is reflects the changes. But still it will not automatically fire Synckolab. Manual syncs work without any problem (none that we've seen - it reflects all the added, changed etc calendar events). In short: Synckolab does not fire automatically with any setting who have thought of.

• Internet printing : print to iOS gateway -> AirPrint / something -> Laser printers

  - by user75129

  I've done a bit of research on the Internet, and it looks like I'm on a dead end. My goal is to minimize cost, and be able to send and print documents AUTOMATICALLY (may be 10 or 20 pages per day) to a laser printer in a remote office. The preliminary method is to use: iOS 5.1.1 (JB'ed) with 3G connection, HP (or other brands) printer with AirPrint, iCloud's Documents and may be write some launchd scripts to monitor any new documents in iCloud. May be with other software. I am not sure yet. By using the cloud, I can upload new docs to the cloud anywhere in my city, and the iOS will be able to see them within a reasonable amount of time, then print it. But it seems this combo is not workable. Anyone got any advice on how to make this set up work, or propose other alternatives that requires NO PC or Mac? Currently I have a 3GS with 3G connectivity spare. Need to buy a new printer though.

• Intermittent HTTP 401 errors

  - by forthrin

  I am using an Intranet solution which requires basic HTTP login. However, there is an intermittent error which requires me to log in again, and then the server says "Forbidden" whether I give the correct login information or not. To add insult to injury, Safari (and Chrome) seems to show the login dialog for every included resource in the HTML, and it's impossible to cancel this modal dialog sequence, so the whole browser is blocked until I've pressed Esc some 30 odd times. After an hour, I may gain access again, without having really done anything. My questions: What could cause temporal 401 errors? Why do the browsers show the login dialog 30 times per page load (assumedly for every included resource in the HTML from the same domain)?

• 'Singleton' application - or let the user only launch one instance of a program at the time

  - by Disco

  I'm running a few linux desktops; mainly for kids (yeah, trying to teach them the right OS at early stage) (running Ubuntu 10.10, Gnome) The problem is that they found very funny to make their workstations (actually, old 512 Mb pentium 4) by launching thousands of firefox instances. I'm looking for a way to restrict them to launch 'N' instances of a particular application. Haven't figured yet how. Thought of a monitoring daemon but I think that would be too ressources hungry. Any idea of a script/trick to achieve this ? Note: i might have 1-2 level of users (the kids, and the more grown up kids) so i have also to limit per user; something like user1: 3firefox, user2: 2firefox instances.

• Change Block Tracking settings not retained for a VM on VMWare 5.5

  - by Chris

  I'm trying to enable Change Block Tracking as per this VMWare KB article but the setting ctkEnabled is not being retained in the advanced options or being added to the vmx file. The setting scsi0:0.ctkEnabled is being retained and I see a file vmname-ctk.vmdk in the datastore. I've verified that the vm doesn't have any snapshots but don't see any other suggestions in the KB (or google, of course.) Edit: The last comment on this community post. It's a slightly different circumstance, but suggests that there is an known bug editing these settings in the web-gui.

• Why is hosted storage so expensive?

  - by Mark Henderson

  There are many questions on Server Fault asking why server storage is so expensive. e.g. Why do I have to pay 50 bucks a month per extra gigabyte of storage or Our file server is always running out of space, why doesn't our sysadmin just throw an extra 1TB drive in there? These questions usually come from people who lack an understanding of how enterprise-level storage works and what influences the price. This question is designed to be the "question to end all questions" regarding the price of enterprise storage.

• Log incoming requests on Ubuntu (ports 80, 443)

  - by Maxim Eliseev

  We have Tomcat running on Ubuntu server. It runs a web service, open to the internet. Sometimes it has a sudden spike of traffic and goes down. There is nothing unusual in Tomcat access logs. I guess it is because some of the requests are so 'heavy' that they never finish and hence are not recorded to Tomcat access logs. Is there a way to configure Ubuntu to log incoming requests in the following format (below)? Date, Time, URL (with query string params), IP address (of client) There should be one line per request. Each request should be logged before it is executed. Only incoming requests to ports 80 and 443 should be logged.
