• Is having a [high-end] video card important on a server?

  - by Patrick

  My application is quite interactive application with lots of colors and drag-and-drop functionality, but no fancy 3D-stuff or animations or video, so I only used plain GDI (no GDI Plus, No DirectX). In the past my applications ran in desktops or laptops, and I suggested my customers to invest in a decent video card, with: a minimum resolution of 1280x1024 a minimum color depth of 24 pixels X Megabytes of memory on the video card Now my users are switching more and more to terminal servers, therefore my question: What is the importance of a video card on a terminal server? Is a video card needed anyway on the terminal server? If it is, is the resolution of the remote desktop client limited to the resolutions supported by the video card on the server? Can the choice of a video card in the server influence the performance of the applications running on the terminal server (but shown on a desktop PC)? If I start to make use of graphical libraries (like Qt) or things like DirectX, will this then have an influence on the choice of video card on the terminal server? Are calculations in that case 'offloaded' to the video card? Even on the terminal server? Thanks.

• How can I proxy multiple LDAP servers, and still have grouping of users on the proxy?

  - by Chris

  I have 2 problems that I'm hoping to find a common solution to. First, I need to find a way to have multiple LDAP servers (Windows AD's across multiple domains) feed into a single source for authentication. This is also needed to get applications that can't natively talk to more than one LDAP server to work. I've read this can be done with Open LDAP. Are there other solutions? Second, I need to be able to add those users to groups without being able to make any changes to the LDAP servers I'm proxying. Lastly, this all needs to work on Windows Server 2003/2008. I work for a very large organization, and to create multiple groups and have large numbers of users added to, moved between, and removed from them is no small task. This normally requires tons of paperwork and a lot of time. Time is the one thing we don't normally have; dodging the paperwork is just a plus. I have very limited experience in all this, so I'm not even sure what I'm asking will make sense. Atlassian Crowd comes close to what we need, but falls short of having it's own LDAP front end. Can anyone provide any advice or product names? Thanks for any help you can provide.

• Applications randomly alt-tab? (especially full screen games)

  - by Henry Scotts

  I'm not sure when this began, how it happens, or why it happens, but it is quite bothersome and apparently random. Just randomly throughout the day my computer will just go to the desktop. I could be in a full screen game and it will just immediately alt tab and present the desktop. Or I could be watching a movie and this happens. Sometimes it happens once every three hours and other times (just today actually) it did it twice in the span of 30 seconds. I am positive I am not pressing a hotkey because I launched a game, sat idle, and noticed it alt tab while cleaning up around my room after about 20 minutes. Sometimes it goes days without this happening. Specs: Windows 7 Ultimate 64 Bit, 10 gigs of RAM, GeForce GTX 260, Intel Xeon CPU. I also have basically nothing running when it happens other than the game and FireFox. My FireFox add-ons: Adblock Plus, Download Statusbar, Firebug, FirePHP, lazarus form recovery, tree-style-tabs, yslow. I doubt FireFox is causing the issue but I figured I'd include it anyway because it is the only application I have running when it happens. As for user processes I have running: VCDDaemon (context menu for virtual clone drive), razerhid (mouse), OSD, taskhost, dmw (desktop window manager), anyfullscreengame, audiorepeater, netsession_win, explorer, razerofa, tsvncache, firefox, plugin-container, and EKIJ5000MUI (printer). Whew. Okay. That was a lot of information. If someone could diagnose this I would be most grateful for this has been around with me for years.. Thanks for reading! PS: I doubt it's a virus because I never download illegal software and pretty much only browse Reddit and Stackexchange and play games. If it was a virus it would be a pretty lame one.. Hah..

• Best Practices for adding Exchange Archive to current 3 server setup

  - by ADquestion

  I'm looking to add an Archive Database (which I know is just a Mailbox Database) to our current Exchange 2010 environment. I have done this in the past at a previous job, but we had a simpler setup than at this current job. I've been trying to find some best practices to make sure it's setup in an ideal way, but so far not finding the details I would prefer. Hoping someone on here can give me a few pointers. Currently we have a 3 server setup, Server1, Server2 and Server3. Three databases of course, DB1, DB2 and DB3. We have a DAG setup between them. Server1 has DB1 and DB3 on it, DB1 is not active, DB3 is active. Server2 has DB1 and DB2 on it, both are active. Server3 has DB2 and DB3 on it, both are not active. All three servers are virtual (VMware). Each one is setup identical to the other as follows: C:\ 60GB - OS E:\ 600GB - DB (currently only 90GB used, pointing to Datastore just for Server2) F:\ 200GB - Log (2GB used, pointing to same Datastore as above) G:\ 200GB - Restore (0 used, pointing to same Datastore as above) The drives are all set to Thin Provisioning, and it looks as though I have 600GB of available space. They have not been on Exchange that long and only have about 70GB worth of PSTs to import back in that will be going to the Archive Database, plus anything older than 2 years from their current inbox that will be moved into there. I was considering placing the Archive DB on the E:\ drive of Server3 (only) like the current DB, but wasn't sure if that was acceptable. I don't plan on setting the Archive DB up with the DAG, just plan on having it as a single repository for older emails and manually back it up every now and then. If anyone has any suggestions on this I would appreciate it the input. I've done it on a slightly smaller scale before and it worked well, but like to think it through before pulling the trigger, especially at a new job. :) Thanks again!

• Apache serving empty gzip with assets produced by Rails Asset Pipeline

  - by PizzaPill

  I followed the steps described on the blogpost The Asset Pipeline, from development to production and tweaked them to my environment. The two important files are: /etc/apache/site-available/example.com <VirtualHost *:80> ServerName example.com ServerAlias www.example.com DocumentRoot "/var/www/sites/example.com/current/public" ErrorLog "/var/log/apache2/example.com-error_log" CustomLog "/var/log/apache2/example.com-access_log" common <Directory "/var/www/sites/example.com/current/public"> Options All AllowOverride All Order allow,deny Allow from all </Directory> <Directory "/var/www/sites/example.com/current/public/assets"> AllowOverride All </Directory> <LocationMatch "^/assets/.*$"> Header unset Last-Modified Header unset ETag FileETag none ExpiresActive On ExpiresDefault "access plus 1 year" </LocationMatch> RewriteEngine On # Remove the www RewriteCond %{HTTP_HOST} ^www.example.com$ [NC] RewriteRule ^(.*)$ http://example.com/$1 [R=301,L] </VirtualHost> /var/www/sites/example.com/shared/assets/.htaccess RewriteEngine on RewriteCond %{HTTP:Accept-Encoding} \b(x-)?gzip\b RewriteCond %{REQUEST_FILENAME}.gz -s RewriteRule ^(.+) $1.gz [L] <FilesMatch \.css\.gz$> ForceType text/css Header set Content-Encoding gzip </FilesMatch> <FilesMatch \.js\.gz$> ForceType text/javascript Header set Content-Encoding gzip </FilesMatch> But apache seems to send empty gzip files because the testsite looses all styles and firebug doesnt find any content for the css files. Altough if I call the assets-path directly I get some gibberish that looks like binary data. If I move the htaccess-file everything is back to normal. How could I find out where/what went wrong or do you have any suggestions what error I made? > apache2 -v System: Server version: Apache/2.2.14 (Ubuntu) Server built: Mar 5 2012 16:42:17 > uname -a Linux node0 2.6.18-028stab094.3 #1 SMP Thu Sep 22 12:47:37 MSD 2011 x86_64 GNU/Linux

• apache2 server running ruby on rails application has go daddy cert that works in chrome/firefox and ie 9 but not ie 8

  - by ryan

  I have a rails application up on a linode ubuntu 11 server, running apache2. I have a cert purchased from godaddy, (where we also bought our domain) and the cert is installed on my server. Part of my virtual host file: ServerName my_site.com ServerAlias www.my_site.com SSLEngine On SSLCertificateFile /path/my_site.com.crt SSLCertificateKeyFile /path/my_site.com.key SSLCertificateChainFile /path/gd_bundle.crt The cert works fine in Chrome, FireFox and IE 9+ but in IE 8- I get this error: There is a problem with this website's security certificate. The security certificate presented by this website was issued for a different website's address. I'm hosting multiple rails apps on this same server (4 right now plus some old php sites that don't need ssl). I have tried googling every possible combination of the error/situation that I could think of but at this point I'm shooting in the dark. The closest I could come up with is that some versions if IE don't support SNI. But that doesn't apply here because I am getting the warning on windows 7 machines running IE 8, and the SNI only seemed to apply to IE 8 if the operating system was windows XP. So why is this cert being accepted by all browsers but giving me a warning in IE 8? Edit: So doing a little more digging and I figured out some more. It turns out this is effecting IE 9 as well. However the problem seems to be that IE is not traversing the ssl chain to get to the right cert. FireFox and Chrome when I go to view certificate show the correct one, but IE is showing one of our other sites certificates. REAL QUESTION HERE: That being the case why is IE not getting the right certificate when others are and how do I fix it?

• CLOSE_WAIT sockets burst - perhaps because of iptables settings?

  - by Fabrizio Giudici

  I have an Ubuntu 12.04 server virtual box where basically the installed software and configuration are the default ones, plus the installation of a jetty 6 server which servers a few websites. To keep things simple I didn't install apache httpd and used iptables for exposing jetty (which runs on the 8080 port) to the port 80. These are the results of /sbin/iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere localhost tcp dpt:http redir ports 8080 REDIRECT tcp -- anywhere Ubuntu-1104-natty-64-minimal tcp dpt:http redir ports 8080 Chain INPUT (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere localhost tcp dpt:http redir ports 8080 REDIRECT tcp -- anywhere Ubuntu-1104-natty-64-minimal tcp dpt:http redir ports 8080 Chain POSTROUTING (policy ACCEPT) target prot opt source destination I must confess I have a shallow comprehension of how iptables works, in particular for the different kind of chains. This thing works, but sometimes I have an explosion of sockets that stay permanently in CLOSE_WAIT state. I know about what this state means, but since I didn't write the code that manages servlets (they are handled by jetty) I can't fix the problem by patching my code. Eventually the amount of CLOSE_WAIT sockets builds up and makes the server not responsive, so I have to restart jetty. I've looked around for similar problems wth CLOSE_WAIT, and only found cases related to the programmer's code, or problems with Tomcat, not Jetty. I was wondering whether they could be related to a partially broken iptables configuration (the alternative is a bug in Jetty 6, but I first want to exclude other possible causes). Thanks.

• Windows Server 2012 Hyper-V very slow

  - by Matt Taylor

  I have been running several Hyper-V VMs on Windows Server 2008 R2 for the past couple of years and enjoying perfectly adequate performance for my testing/development/r&d environments. I'm a software developer so my hardware knowledge is basic however I built the rig using: •Gigabyte GA-X58A-UD3R Intel X58 (Socket 1366) DDR3 Motherboard •Intel Core i7 960 3.20GHz (Bloomfield) (Socket LGA1366) •24GB triple channel RAM The host OS is running on an OCZ SSD and all the VMs are running on a 2TB Marvell SATA3 RAID 0 array consisting of 2 Western Digital Caviar Black 7,200rpm drives. I have tested the speed of the 2TB drive and appear to be getting less than 3Mbs but it can adequately run a 4 VM farm including a DC, (SQL) database and IIS application servers. I recently upgraded the SSD on which the host runs to a 256GB OCZ Vertex 4 and took the opportunity to upgrade to Windows Server 2012 and installed the Hyper-V role. I tried importing one of my existing Windows Server 2008 R2 VMs (and converted it to .vhdx) plus I have tried creating a brand new Windows Server 2008 R2 VM but both are running extremely slowly and I can see nothing obvious using the host and guest Task Manager/Resource Monitor tools. In both cases the VM has 8GB RAM (fixed), 4 CPUs, fixed size HD (not expanding) and is using an external virtual network running on a separate NIC to the host. I have upgraded the BIOS to the latest available version and checked the virtualization settings. I have run out of "obvious" (to a developer) things to check/configure and my next option will be to re-install the host OS but before I do I would very much appreciate any advice from any experts out there. Thanks

• setup lowcost image storage server with 24x SSD array to get high IOPS?

  - by Nenad

  I want to build let's name it a lowcost Ra*san which would host for our social site the images (many millions) we have 5 sizes of every photo with 3 KB, 7 KB, 15 KB, 25 KB and 80 KB per Image. My idea is to build a Server with 24x consumer 240 GB SSD's in Raid 6 which will give me some 5 TB Disk space for the photo storage. To have HA I can add a 2nd one and use drdb. I'm looking to get above 150'000 IOPS (4K Random reads). As we mostly have read access only and rarely delete photos i think to go with consumer MLC SSD. I read many endurance reviews and don't see there a problem as long we don't rewrite the cells. What you think about my idea? - I'm not sure between Raid 6 or Raid 10 (more IOPS, cost SSD). - Is ext4 OK for the filesystem - Would you use 1 or 2 Raid controller, with Extender Backplane If anyone has realized something similar i would be happy to get Real World numbers. UPDATE I have buy 12 (plus some spare) OCZ Talos 480GB SAS SSD Drive's they will be placed in a 12-bay DAS and attached to a PERC H800 (1GB NV Cache, manufactured by LSI with fastpath) Controller, I plan to setup Raid 50 with ext4. If someone is wondering about some benchmarks let me know what you would like to see.

• unable to access Internet by wireless but can by cable

  - by Jeff King

  i'M GOING MAD! UNtil last friday I had been successfully using wifi with the supplier as VIRGIN through their Motorola SB 4200 cable Modem and the wireless router being the Linksys WRT 54G router. Supported were three lap tops and an EPSON 510W printer and this had been running with no issue for about 3 years. Back to last friday, we started suffering significant delays and then the network collapsed with no wireless access. I was able to connect a single laptop direct to the cable modem and internet access was restored to just that one device. I thought that the problem was the router so I tried a backup D-Link device with no success. I have subsequently bought another cable modem AND a netgear router plus addidtional ethernet cables but with no success. The best that happens is that the signal appears good but I cannot get access to the internet. A yellow question mark appears on the 'gradient' icon. Each laptop and router works elsewhere so I'm stumped. Mind you I am a real novice so I'm not surprised. Please can anyone tell me what I'm doing wrong?

• Missing access log for virtual host on Plesk

  - by Cummander Checkov

  For some reason i don't understand, after creating a new virtual host / domain in Plesk a few months back, i cannot seem to find the access log. I noticed this when running /usr/local/psa/admin/sbin/statistics The host in question is being scanned Main HTML page is 'awstats.<hostname_masked>-http.html'. Create/Update database for config "/opt/psa/etc/awstats/awstats.<hostname_masked>.com-https.conf" by AWStats version 6.95 (build 1.943) From data in log file "-"... Phase 1 : First bypass old records, searching new record... Searching new records from beginning of log file... Jumped lines in file: 0 Parsed lines in file: 0 Found 0 dropped records, Found 0 corrupted records, Found 0 old records, Found 0 new qualified records. So basically no access logs have been parsed/found. I then went on to check if i could find the log myself. I looked in /var/www/vhosts/<hostname_masked>.com/statistics/logs but all i find is error_log Does anybody know what is wrong here and perhaps how i could fix this? Note: in the <hostname_masked>.com/conf/ folder i keep a custom vhost.conf file, which however contains only some rewrite conditions plus a directory statement that contains php_admin_flag and php_admin_value settings. None of them are related to logging though.

• organizing my music and my itunes

  - by Cawas

  What can we do to organize our music? I've got over 20k items on my iTunes Library, at least 5k with ratings and play counts, apparently just 12k music files and I can't understand how this question have not been properly answered yet. Maybe there is no answer. I have too many duplicates, broken links, bad music, corrupted files... Well, a big mess with no tags! Probably there's no single software capable of just organizing everything, though I'd love one. Hopefully some time in the near future we all will be able to just sync the cloud of our automagically selected music to the newly created offline copy. But meanwhile... Please, do consider I've at least gave a shot (even while not a full test drive) to every single answer linked here already, plus a few more. I'm fine with using other software (mac too, please) to organize, but I'd need it to sync (retrieve and put back) at least iTunes ratings, because of iPhone and smart playlists. Not looking for iTunes replacement. I'm hoping to hear what you hardcore music organizers out there are using as your own solutions! :) I myself am using way too many tools, getting way too little done and end up going song by song.

• OpenLDAP ACLs are not working

  - by Dr I

  First things first, I'm currently working with an OpenLDAP: slapd 2.4.36 on a Fedora release 19 (Schrödinger’s Cat). I've just install the openldap with yum and my configuration is the following one: ##### OpenLDAP Default configuration ##### # ##### OpenLDAP CORE CONFIGURATION ##### include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema pidfile /var/lib/ldap/slapd.pid loglevel trace ##### Default Schema ##### database mdb directory /var/lib/ldap/ maxsize 1073741824 suffix "dc=domain,dc=tld" rootdn "cn=root,dc=domain,dc=tld" rootpw {SSHA}SECRETP@SSWORD ##### Default ACL ##### access to attrs=userpassword by self write by group.exact="cn=administrators,ou=builtin,ou=groups,dc=domain,dc=tld" write by anonymous auth by * none I launch my OpenLDAP service using: /usr/sbin/slapd -u ldap -h ldapi:/// ldap:/// -f /etc/openldap/slapd.conf As you can see it's a pretty simple ACL which aim to allow access to the userPassword attribute to a specific group read only, then to the owner read and write to anonymous requiring auth and refuse the access to everyone else. The problem is: Even using a valid user with correct password my ldapsearch ends with zero informations retrieved from the directory, plus I've got a strange response on the result line. # search result search: 2 result: 32 No such object # numResponses: 1 here is the ldapsearch request: ldapsearch -H ldap.domain.tld -W -b dc=domain,dc=tld -s sub -D cn=user,ou=service,ou=employees,ou=users,dc=domain,dc=tld I did not specify any filter as I want to check that ldapsearch is correctly printing only allowed attribute.

• How do I fix error 1303 during TI Connect install?

  - by smoth190

  I recently purchased a TI-84 Plus graphing calculator, and I'm trying install the TI Connect software in order to connect the calculator to my computer via the USB cable. Unfortunately, I'm getting this error while trying to install the program: Error 1303. The installation has insufficient privileges to access this directory: E:\Data\Timothy\Documents\MyTIData. The installation cannot continue. Log on as administrator or contact your system administrator. However, my account is the only account on my PC, and it has administrative privileges. I've also tried running the installer with Run as Administrator, but with no luck. If I create the folder MyTIData manually, I receive this error: Error 1317. An error occurred while attempting to create the directory: E:\Data\Timothy\Documents\MyTIData I've reapplied the security settings to the E:\Data folder (and all its sub-directories) to Full for my account. I've also gone into Computer Management, and given SYSTEM full privileges for the entire disk. I've also logged out, logged back in, restarted, etc. but still, no luck. Now, I should mention that my Documents folder is not at the default location. I changed it due to my C: disk being a 90GB SSD, so I moved all my personal data onto the extra storage disk (which is ~1TB). I don't know if that is causing the issue, but it can't hurt throwing it out there. So why can't I install this program? Google'ing the problem brings up this error for various other installers (such as Visual Studio and Microsoft Office), but nothing for TI Connect. All the solutions are the same: Give the folder Full privileges...but I've already done this! I've also tried running the installer with and without the calculator plugged in, but it didn't change anything. In the prompt that contains the error, repeatedly clicking Retry or waiting a few moments before clicking Retry also produces no result.

• Zsh super slow inside my Git repo

  - by Jason Swett

  My Zsh is super slow inside a certain Git repo of mine. When I Google "zsh git slow", I get a bunch of results about Git autocompletion being slow, but autocompletion isn't necessarily my problem; it's everything. I tried removing all plugins and that, strangely, didn't do anything at all when I opened a new shell. Zsh would still do Git stuff inside my Git repo. I found this snippet on this page: function git_prompt_info() { ref=$(git symbolic-ref HEAD 2> /dev/null) || return echo "$ZSH_THEME_GIT_PROMPT_PREFIX${ref#refs/heads/}$ZSH_THEME_GIT_PROMPT_SUFFIX" } That made everything fast again, but it also gave me a prompt that looks like this: ? snip git:(master Note the missing right parenthesis. That's kind of lame. Plus the whole thing just seems like a hack I shouldn't have to do. There's also this promising-looking SU question, but the links on the accepted answer are dead. How can I get my Zsh not to be slow inside a Git repo?

• Dynamically blocking excessive HTTP bandwidth use?

  - by Jeff Atwood

  We were a little surprised to see this on our Cacti graphs for June 4 web traffic: We ran Log Parser on our IIS logs and it turns out this was a perfect storm of Yahoo and Google bots indexing us.. in that 3 hour period, we saw 287k hits from 3 different google ips, plus 104k from yahoo. Ouch? While we don't want to block Google or Yahoo, this has come up before. We have access to a Cisco PIX 515E, and we're thinking about putting that in front so we can dynamically deal with bandwidth offenders without touching our web servers directly. But is that the best solution? I'm wondering if there is any software or hardware that can help us identify and block excessive bandwidth use, ideally in real time? Perhaps some bit of hardware or open-source software we can put in front of our web servers? We are mostly a windows shop but we have some linux skills as well; we're also open to buying hardware if the PIX 515E isn't sufficient. What would you recommend?

• How to download Vim script on the command-line?

  - by HaiYuan Zhang

  Whenever I want to install a new Vim script on the Linux server I'm working on, my typical workflow is as the following: surf the plugin's homepage in Vim online using FireXXXX download a right version of the plugin to my laptop by click some highlighted link upload the downloaded plugin from my laptop to Linux server using WinSCP which is really inconvenient. I don't know what is the magic behind this: I mean for the same hyperlink I click it in web browser. I can let you download it but use Wget plus the hyperlink in Linux command-line will end up with nothing but an error indication. Hyperlink in the web browser. Otherwise I can get the link in web browser and then use Wget or some similar tool to actually do the downloding. I try new cool Vim scripts quite ofte , so you can imagine my dismay when I have to repeat the tedious action all the time. What are some tips which can let me download the Vim scripts in a more "professional" way? Post edit: My problem is not find a tool like Wget or cURL. The problem I met is quite specific; to use these tools to download a Vim script. Let's take http://www.vim.org/scripts/script.php?script_id=30 as an example. It's the normal place where one can get the script, at least for me. But I can't find an working URL from this page that can feed to Wget.

• What is the best cloud technology to use for MongoDB/GridFS database servers

  - by Nerian

  We are going to launch a service that will require between 1 and 2 GB for file storage per paid user. I am going to use GridFS for storing files. GridFS is a module for MongoDB that allows to store large files in de database. I am pondering the different options for storing the database. But since I am unexperienced at deployment and it is my first time with Mongodb I need your experience. Criteria: I want to spend my time developing my core business, that is, my own application. I am a Ruby on Rails developer. I do not like to mess with server configuration. Hence, I would like a fully managed hosting solution. But I would like to know about any other option, if you think it is worth it. It should be able to scale. Cloud style. Pay as you go. The lower the price, the better. So far I known of these services: https://mongohq.com/pricing https://mongomachine.com/pricing https://mongolab.com/about/pricing/ http://cloudcontrol.com/add-ons/mongodb/ And they seem to be OK for common needs, that is no file storage. But I am going to use GridFS, so the size matters. These services seems to scale, in price, quite poorly. MongoHQ: The larger plan max storage is 20 GB. Seems like a very little storage, for GridFS. MongoMachine: Flat price, 2.5$ per GB. I didn't found the limit. Seems like a good price, comparing the others. MongoLab: 3.984 GB max, which I don't think I will hit, so perfect. 8$ per GB, quite costly. CloudControl: The larger plan is 20 Gb. The custom service starts at 250€ plus some unspecified charge per GB. What is your experience with these services? Any downtimes? Other possibilities? Edit: Added meaning of GridFS

• HP dv6910 laptop no longer recognizes wireless adapter, dvd drive, and one usb port. What can I do about this?

  - by Joan H.

  In the last 3 weeks, my not even 3 year old HP laptop (vista) just seems to be failing. First, one of the usb ports stopped working. Next, the dvd drive all of a sudden was not recognized as even existing, so it is now useless. And as of today, I no longer seem to have a wireless adapter on my laptop. It doesn't show up in device manager, same as the dvd drive. I can connect to the internet by ethernet cable, but not wirelessly. It worked fine last night; now it doesn't even exist! I have tried a 'hard reset' I read about on HP's forum- no help. I am not sure what else to try. I read about the USB wifi dongle in another response, but I already have maxed our my usb ports even though I have bought a USB hub since the one port failed. Plus, I'd like my laptop to just work like it's supposed to instead of being jerry rigged with usb hubs, external dvd drives, and wifi dongles etc. Any ideas?

• Which project management software for technophobes who've never worked with something like that?

  - by Ernst

  Hi, Our director has asked me to get something to manage projects. Note that so far we haven't used anything of the sort. I did not get very clear instructions yet, probably because she doesn't know exactly what we need either. My guess is, we'll only find out while using something. I've looked at some, openworkbench, ganttproject, and microsoft project. The latter has the advantage of easy importing of users from exchange, are there others that do that (even if not directly, easily)? I don't think it's a critical requirement though. We're using some other custom software where I have to add users manually anyway and we're small enough that it's maybe once a month that I have to add or remove a user. In any case, I'm not in favour of buying anything, since I'm skeptic about us actually succeeding in putting it to good use, and even if we do, we will only during usage discover what we need. We're also not a tech shop, most people vary from not very technically adept to technophobic. This means we need something very userfriendly. I prefer to stay away from online solutions, since we deal with sensitive information and I prefer to keep that in house, but I guess it would be acceptable for the trial period. An intranet site is an option though, but preferably something that is easy to set up with IIS. Xplanner plus and redmine I found too hard to set up for this experiment. Some other options I haven't yet tried to install, but which look to complex for our technophobes: Endeavour Software Project Management, Project-Open, Trac. Any suggestions? Thanks, Ernst

• Freebsd jail for an small company - checklist - what shouldn't forget

  - by cajwine

  Looking for an checklist for an "small company freebsd/jail server". Having pretty common starting point: FreeBSD jail (remote/headless) for the company: public web, email, ftp server, and private (maybe in the future partially public) wiki (foswiki) 4 physical persons, (6 email addresses) + one admin - others will never use ssh) have already done usual hardening on the host side (like pf, sshguard etc). my major components are: dovecot, exim, apache22, proftpd, perl5.14. Looking for an checklist, what I shouldn't forget. My plan: openssl self-signed certificates for exim, dovecot and proftpd (wildcard keys) openssl self-signed certificate for apache (later will go for "trusted-signed" key) My questions are: is is an "good practice" having one pair of wildcard SSL-certificates for many programs? (exim, dovecot, proftpd) - or should I generate one key for each service? should I add all 4 persons as standard (unix) users, or I should go with virtual users? Asking because: have only small count of users, and it is more simple to configure everything (exim, dovecot) for local users ($HOME/Maildir), plus ability to set $HOME/.forward/vacation and etc. is here some (special) things what I should consider? (e.g. maybe, in the future we want setup our own webmail - will make this any difference?) any other recommendation? Thank you, hoping that this question fit into the http://serverfault.com/faq under the: Server and Business Workstation operating systems, hardware, software Operations, maintenance, and monitoring Looking for an checklist, but please explain why you're recommending it. See Good Subjective, Bad Subjective. related: What's your suggested mail server configuration for a FreeBSD server?

• How to prevent asymmetric routing with multiple eBGP routers?

  - by Andy Shinn

  I have 2 routers announcing a /22 subnet to different providers (one providers connects to each of the 2 routers). I have split the /22 in two /23 to announce one /23 on each of the routers plus the /22 (the providers will take the more specific route). This allows me to fail over and keep traffic inside the /23 in and out the same provider. What are other ways in which I could announce just the /22 with both routers and have packets from servers on the network behind the routers go back out the same router in which they came in from? EDIT: The main problem I come across, which end users and clients complain about the most, is that the least hop route is sometimes not the "optimal" route. In my case, I know that Provider B may have better latency to X nation. But when packets come in from provider B, they may go out Provider A or provider B. The reverse is also true. If I send a packet to X nation out provider A, even though it may have more hops back, the packet will likely come in from Provider B (which may have higher latency, packet loss, etc. to this nation)

• Firefox: Unload a tab manually

  - by unor

  Firefox has a setting "Don't load tabs until selected" (see How do I make Firefox 13 Load All My Tabs on Startup or when Resuming Reload). I like that behaviour. I am searching for a way to "deload"/deactivate a tab manually for a session (until I reload it). It should stop all running JavaScript functions and plugins (like Flash). The whole webpage content may disappear until I reload/re-activate the tab, but that is not a requirement. The title has to be displayed as tab label (like it is the case with the startup setting, too). The workaround would be to restart Firefox and don't switch to the tab I want to be deactivated. This is pretty annoying, of course. EDIT: Here is what I found so far (thanks, @bytebuster!) BarTab no longer being maintained (see why) BarTab Lite seems to miss this functionality from BarTab Dormancy experimental; comes with warning that it "may eat your session" Tab Mix Plus Feature request: Unload Tab feature Tab Utilites seems to offer this functionality only for automatic unloading Feature request: Add "unload tab" to tab context menu. UnloadTab removed from addons.mozilla.org (who knows why)

• Mass-migrating from POP3 to Exchange 2010, how do I copy mailboxes?

  - by Erik P. Skaalerud

  I'm in the process of planning our migration from an internal hosted POP3-server (dovecot) to Exchange 2010. We're using Outlook 2003 for the moment, but will soon upgrade to Outlook 2010. The big problem is that we have about 50 computers here in our HQ, plus ~30 clients in branch offices (wich will get their Exchange migration later sometime). I'm the only IT personel, and having to go around and manually set up Outlook and copy over their PST contents is not a option I'm looking for. Some users have set outlook to keep messages for X number of days on the POP3 server, others have not. Using a POP3 connector to transfer over the mails is not a viable option. Here is what I've done so far: Created a transform for the Office 2003 administrative installation point Created a .PRF file to modify any existing e-mail account to switch over to Exchange (including the RPC-encrypt hotfix described in MSKB 2006508) Tested both transform and PRF, both works Created a test-OU and GPO containing the Office 2003 installation with transform applied, also works My big question is: How can I force Outlook to import any existing .PST into the new Exchange mailbox when the user starts up Outlook for the first time after the MST/PRF have been applied? Is this possible?
