• IT Inventory Tracking

  - by DrStalker

  What is a good tool to keep track of IT inventory? Systems that are installed and running, parts being ordered, that sort of thing. I'd love a central, web based system (preferably something we can customize) but my searching so far has resulted in a lot of dead open source projects that havn't been updated in a few years and poorly created commercial websites that don't do a very good job describing their product. The software doesn't have to be free or open source - a good commercial alternative is fine. It doesn't even need to be a web-based tool, that's just what I thought would be simplist to find and easiest to deploy. The number of assets that it will be tracking will be in the dozens, so it doesn't have to be a super high-end enterprise solution but it does need to do a better job than an excel sheet in a shared folder (which is our current "solution")

• What hardware makes a good MongoDB Server ? Where to get it ?

  - by João Pinto Jerónimo

  Suppose you're on dell.com right now and you're buying a server to run your MongoDB database for your small startup. You will have to handle literally tens of thousands of writes and reads per minute (but small objects). Would you go for 2 processors ? Invest more on RAM ? I've heard (correct me if I'm wrong) MongoDB handles the most it can on the RAM and then flushes everything to the disk, in that case I should invest on a CPU with a large L2 cache, probably 40GB of RAM and a solid state drive.. right ? Would I be better off with a high end (~$11,309, 2 expensive processors, 96GB of RAM) server or 2x(~$6,419, 2 expensive processors, 12GB of RAM) servers ? Is Dell ok or do you have better sugestions ? (I'm outside the US, on Portugal)

• Which file format to use for simple video editoring

  - by Craig HB

  I've just bought a Sanyo VPC-CG10 camcorder which saves clips as MPEG-4 (specifically, High-Definition 720p MPEG-4 AVC/H.246) I want a simple, cheap way to edit the clips and as, I'm using Windows Vista, I though Windows Movie Maker would be a good choice. But you can't import mp4 files into Windows Movie Maker. I've tried various codecs, but I'm not sure what is the best format to convert to, so that I can edit the files in Windows Movie Maker. AVI, MPG, WMI... I'm not sure what format is best. Should I try to keep the movie clips in MPEG-4 and edit them in that format (and then which editor do I use?) or is there a better format that I should convert to before editing (and what format is that?) ?

• How to scale out OpenStreetMap data efficiently

  - by Pierre

  For over a year now, I'm running an in-house PostGIS server filled with OSM data, used for both Mapnik-based tile generation and Nominatim-based geocoding, updated with day replicates. This works pretty well. However, as usage is growing exponentially, I would like to achieve better reliability and performance by adding additional PostgreSQL servers. And I'm kind of lost. Since PostgreSQL doesn't seem to handle replication by itself, I would think about using a piede of middleware like PgPool-II to keep the servers in sync. But I'm afraid it would be nothing but necessary for this usage : very high read-to-write ratio, where all writes are done at the same exact time every day. My questions are simple : What would you do to keep these servers in sync? And, what is done for this at the OpenStreetMap Foundation, MapQuest, Mapbox or CloudMade? Thanks.

• What can I do to enhance MacBook Pro internal mic sound quality in iMovie?

  - by gaearon

  After using MacBook for two years, I bought 17'' MacBook Pro. I'm pretty happy with it, performance and all, but I also was going to record some music videos for YouTube. I play guitar and sing. However I was extremely disappointed with the sound quality that comes by default. I'm 100% sure my 13'' MacBook mic was much better at recording music and singing. Currently mic can't event handle acoustic guitar, outputting sound you'd think was recorded 5 years ago in ARM format on a Nokia phone on a loud concert. It totally feels like some lame filter is cutting low and high frequencies. I want to know what settings (visible or hidden) in iMovie or Mac OS itself I might want to tweak in order to get my MBP mic record clean sound.

• A home router for torrents, gaming, webbing and detailed QoS [closed]

  - by Cawas

  I want to plug in an external HD on it to torrent up never ending (mostly for seeding), with lowest priority. It should even automatically completely stop if it disturbs my net usage, and go back in later. And I want to be able to give gaming (or my computer) the highest priority, because of its ping requirements. It should be above even of Skype and any voip, which also have high priority. Web surfing and "youtubing" comes in the middle - it won't matter much if it delays a second or two. Finally, interface as simple as possible. It's fine if it's command line setup, but it needs to have a GUI. What are my options for routers / firmwares as described? Maybe Gargoyle? Or even Time Capsule? It seems to me good old DD-WRT isn't the best option out there anymore. I wonder what else could cover these grounds.

• How to automatically resume php-fpm?

  - by alfish

  I am using nginx+php-fpm on Debian Squeeze for a busy server and have had great difficulty to deal with maximum connections being reached. Here the problem is that php processes sometimes just die randomly under high load and leave the server with no php process. Then I need to manually restart php5-fpm service to bring back the server to life. I am wondering how to avoid this to happen, or at least treat the symptoms by restarting the php5-fpm automatically whenever there is not php process left to listen to incoming requests. My relevant configs are: pm = dynamic pm.max_children = 1400 pm.start_servers = 10 pm.max_spare_servers = 20 pm.process_idle_timeout = 1s; #not sure it will be useful when pm=dynamic pm.max_requests = 100000 request_terminate_timeout = 30 I appreciate your suggestions to cope with this nasty problem.

• Setting up SharePoint 2010 guides

  - by RobertPitt

  I'm looking for some guides on setting up SharePoint Server 2010. The guides should be focused on the actual web interface side of things such as Permissions, Layouts, Team Sites etc. I have searched high and low for guides and most of them are just "How to install Server 2010". These are useless because the installation is self explanatory. I'm at the stage where I need to learn the config side of things so I can lay my web structure out the way I want it. Has anyone got any good resources?

• Linux Live CD for old computer

  - by Joel Coehoorn

  I have a pentium II (that's right, pentium II) with a scant 200MB of ram. This was a high-end workstation in it's day. The machine currently runs dos on a raid array, and I need to pull some data from it. I figure my best chance at this is to use a linux live cd to copy the data to one of our active directory network shares (there is a network card in the machine). Unfortunately, my linux skills are abysmal, so I'm not sure where to get started: Where should I look to find a linux cd that will run well on such an old system Since I'm likely gonna need to be command-line only, what do I need to do to configure the network card and mount the network share via the command line? Bonus points: exact syntax needed to copy and convert the entire volume for use in VMware server 2.0, but really just copying all the data should be enough.

• How to force my laptop to use the discrete GPU?

  - by Anton Roth

  My laptop (Asus X7BSV) is stuck using only the integrated GPU. It has a nVidia GT540M as well, but I cannot get it to work. I am using a Windows 7 x64 with latest drivers. This occurred after I attached an external USB monitor I need for work, and since then I cannot swap back to the nVidia GPU (dxdiag for example says that the primary GPU is the Intel integrated one). Asus support asked me to completely reinstall the system, but that is something I do not want to do. I checked the BIOS, there is no option as to what GPU to use. The nVidia card itself is working, since I can use CUDA on it, and it worked with a Ubuntu Live CD. In the nVidia software management I tried setting it to global setting, high performance GPU (nVidia), but that had no impact. What am I missing here? I did uninstall/delete all drivers and software related to the external monitor, but that did not help.

• Regarding temperature in our server cabinet

  - by kafka

  We have a floor standing server cabinet, which sits in the corner of our office. There is no AC in the office, and the average temperature is around 21C (70F). The server cabinet currently contains 2 tower servers, a switch and a router. It's well enough ventilated, but does get understandably warm in there. We've recently put a thermometer in there to monitor the temperature, and recently I've noticed the temperature hit 33C (91F). What I'd like to know is if this temperature is too high, and whether there is a maximum temperature we should not be exceeding?

• Severe latency only on one machine and only when accessing intranet site

  - by Joe M.

  I have one desktop machine that is having consistently high latency only when trying to load a page from an intranet site. Using the Chrome Developer Tools, the site shows a "Waiting" time of 4-5 seconds each page load. Other machines have <50ms, and the problem machine loads regular internet sites with <1s latency, so the problem is only on one machine and only when accessing the intranet site. This is a small business and all the hosts are on 192.168.0.1/24 I would have suspected a connection issue with the problem machine but normal internet sites are not having latency. Then I would have looked at connection issues with the intranet web server but other machines are not having latency to it. What else can I look at to troubleshoot this?

• Looking for a good Web Server that is cheap

  - by SoLoGHoST

  I am a Project Manager, and former Lead Developer for a software portal system that requires a forum software to run. I am in need of a server that is cheap, reliable, and supports the latest PHP (5.2+), MySQL, unlimited e-mails (preferably), a cPanel, multiple sub-domains (atleast 3+). Currently I am paying $34.95 USD/month (approx. $420 USD/year). This is too high for me to pay to keep the site running. I just recently became Project Manager and in charge of Finances and I'm extremely concerned for the future of Dream Portal. With those prices I'm not sure I'll be able to keep it running for too long. Can someone please tell me of a good server that meets all of the requirements that I listed above that is cheaper on a yearly basis? Note: Currently on a Dedicated Server with limited disk space at 15000 MB (15 GB), monthly bandwidth = 500000 MB, 50 emails limit, 20 sub-domains limit, 30 FTP accts., and 25 SQL Databases.

• How do ulimit -n and /proc/sys/fs/file-max differ?

  - by bantic

  I notice that on a new CentOS image that I just booted up off of EC2 that the ulimit default is 1024 open files, but /proc/sys/fs/file-max is set at 761,408 and I'm wondering how these two limits work together. I'm guessing that ulimit -n is a per-user limit of number of file descriptors while /proc/sys/fs/file-max is system-wide? If that's the case, say I've logged in twice as the same user -- does each logged-in user have a 1024 limit on number of open files, or is it a limit of 1024 combined open files between each of those logged-in users? And is there much performance impact to setting your max file descriptors to a very high number, if your system isn't ever opening very many files?

• Waht are the best proxy servers for Mikrotik router?

  - by niren

  I want to setup proxy server for my Mikrotik router. There is inbuilt web-proxy for Mikrotik router but I can extend this upto transparent proxy(kind of proxy server) only. We need High anonymity proxy so that we can hide our LAN static IPs(we don't have private IP) from outside Intruder/hackers. And also I know I can setup NAT rule to hide our IP(only private IP not public/static IP) as per this link, but I cann't hide static/public IP. Essentially I want to hide our Public/Static IP (there is static/public IP for all systems in our company) from outside Internet. To achieve this I guess I need other software apart from Mikrotik router gateway setup. can anyone suggest me Is there any other software to achieve my requirement? I know about squid proxy but am not sure whether It can hide our static/public IP. Note: we have assigned public/Static IP to all systems of our company since we have rights to access our company's system from anywhere by dedicated laptop(given by our company with more security) through VPN connection.

• How to analyse logs after the site was hacked

  - by Vasiliy Toporov

  One of our web-projects was hacked. Malefactor changed some template files in project and 1 core file of the web-framework (it's one of the famous php-frameworks). We found all corrupted files by git and reverted them. So now I need to find the weak point. With high probability we can say, that it's not the ftp or ssh password abduction. The support specialist of hosting provider (after logs analysis) said that it was the security hole in our code. My questions: 1) What tools should I use, to review access and error logs of Apache? (Our server distro is Debian). 2) Can you write tips of suspicious lines detection in logs? Maybe tutorials or primers of some useful regexps or techniques? 3) How to separate "normal user behavior" from suspicious in logs. 4) Is there any way to preventing attacks in Apache? Thanks for your help.

• APC and "apc.gc_ttl" :: How Low is Too Low?

  - by nojak

  I currently have my apc.gc_ttl set to 600 to help keep fragmentation down. Since apc.gc_ttl just sets the time on cache for garbage collection, I don't see any harm in keeping it this low. However, I'm new to APC, and have seen many configurations online that use a 3600 TTL, which seems quite long to me for garbage collection cache... Is 600 too low? Is 3600 too high? As I'm sure mileage varies on this setup, is there a good rule of thumb to follow?

• How should I implement an email circuit test?

  - by lukecyca

  I want a high-level test that ensures that both incoming and outgoing email services are operating normally. I've achieved this by writing a python script which does this: Send a message with a unique hash through my mail server to [email protected] The gmail account is configured to auto-reply back to the same address and then delete the message. My script polls IMAP until it finds an email with the correct hash sitting in its inbox, or times out. It reports the elapsed time to my monitoring software (Zabbix) My question: Is gmail the best third-party to use? Should I add a couple others as well such as hotmail and yahoo? Is there anyone more official that will auto-reply to these sorts of "mail pings"? Any other recommendations for this type of test?

• Fast, reliable data transfers from/to China

  - by Nils

  We are a small company and we will need to transfer rather large amounts of data (10GB+ each time) between Europe and China in the near future. As many may have experienced, Internet connections to or from China can be rather unreliable and slow at times without any apparent reason. For example, while sending data to China via FTP generally works well, it can be painfully slow in the other direction. Currently, we are investigating new ways to have high transfer rates in both directions. So far we have tried: FTP (see above) FTP over VPN services (generally slower than direct connections) F2F (like Retroshare or Freenet - slow!!) Aspera (fast but expensive!) BitTorrent (unreachable end nodes, b/c of firewalls which we must not configure) We would like to try: Cloud storage (e.g. Amazon S3, Google Storage) - are those services always and reliably reachable from inside China? Point-to-Point VPN (currently not possible, b/c of the network, see above) I'd be especially grateful to hear from people who have already dealt with this kind of problem before.

• How do ISPs/Colocation Facilities limit bandwidth for Ethernet Drops?

  - by Kyle Brandt

  I have switch providers and have run into some problems with bandwidth limitations. I have more bandwidth then before, but there are performance issues. The router is connected to a 100mBit port, but they limit it to arbitrary settings (in software I imagine). It seems when I go above the limit, the provider starts to drop packets beyond the limit (This is what they said they do as well). Is it possible the previous provider did something like queuing packets above the this limit before dropping them? Is anyone aware of not only what can be done, but what is typical? Also, is there anything I can do on my Cisco router to help this situation? It would seem I am pretty helpless if the packets are dropped before they reach my interface (The traffic that is high is inbound to my network).

• Linux servers vs Windows IIS sense of usage "free" solutions

  - by Rob

  I wonder what is the sense of using "free" open source solutions for serious webstie applications? Crawled and read many testing of servers performance and there is one conclusion: IIS seems to be the best choice for high load applicatiom. I mean cost effective. Especially this concers to Nginx PLUS and LiteSpeed Users where subscriptions paid for e.g. LoadBalacer and extra support cost a lot in fact. I'm asking then where it's "free" then or "cheap" in this case? Assuming even little higher cost of dedicated servers with Windows still seems like Windows looks cheaper. At it's basic setup Windows 2012 with IIS offer much more than std LAMP, or other NGINX config.... Maybe am I missing sth ? I mean only general case for someone who did not already started his app. I know exactly that the cheapest solution is the one someone is skilled. Has anyone done already such real costs calculation for example scenarios?

• Performance issues with new dedicated server [closed]

  - by Pierre Espenan

  I have just subscribed to a new dedicated server and am getting worst than expected PHP execution performance. Execution times are twice as high as on my old mutualized server! I'm definitely not an expert at server management, so I'm wondering what I missed. Here are some stuff that can help you understand what's wrong here : My server (in french but easy to understand) : http://www.online.net/fr/serveur-dedie/dedibox-sc phpinfo(); output : http://jsfiddle.net/E8b7W/embedded/result/ PHP bench script (dedicated server) : http://jsfiddle.net/EhXzK/embedded/result/ PHP bench script (old mutualized) : http://jsfiddle.net/ANbWt/embedded/result/ Is it normal to get such poor performances after a kernel update and basics "apt-get install" for apache2 and php ? Thanks !

• Mysql Master-ColdMaster

  - by enedebe

  I explain my case: I'm at Amazon AWS and I want to be fault tolerant on a entire region failure. My basic problem is to have the db in sync with 2 regions. My options: Master-Master (high lag) Hand made sync every 5 minutes Master-ColdMaster?! (copy on the fly but Master won't wait the other region commit) In my system we could afford loosing a piece of data (we're not a bank) the last inserts in the db, but we could not afford more than 10 minutes of downtime. The database is small and the level of inserts is low, and I wouldn't affect the normal usage waiting other region commit. Is the 3 solution posible? And the most important, once the primary fail how we can detect and change the rol between master-coldmaster -- coldmaster-master ? Is there any clean-mode to restore between failure? Thank's!
