  • Deploy our own software using Puppet?

    - by Ken
    (Apologies in advance for the stupidity in this question. I'm normally a programmer, not a sysadmin, but I've taken it upon myself to automate some things, and clean up some other things which are automated but not in the prettiest way. :-) I've been looking around at various tools for automation of software deployment to a bunch of servers, like cfengine, Puppet, and Chef. So far, Puppet looks the most appealing, but I've certainly not committed to anything yet. These tools all look like they can do a great job of keeping a bunch of servers up-to-date with prepackaged software. What I don't get is: how does one use a tool (like Puppet) to manage deployments of our own internal software? I think I'm at a loss because I've seen a thousand tutorials showing how to keep Apache ensure => latest (which is pretty cool), but nothing that quite corresponds to my use-case today, which is something more like: when a human being pushes The Button, pull branch A from the version-control repository B run command C to compile it copy the binaries D to servers E1 through E10 on each server, run command F to make all changes take effect Puppet sounds great, and I totally see the advantage of declarative, idempotent configuration over some shell scripts, but I've not seen any tutorials for "you want to update your shell scripts to Puppet (or Chef, or cfengine) so here's what you should do". Is there such a thing? Is it obvious to other people how to take the things provided in the Puppet docs and replicate the behavior I want? Am I just not getting it? What it's sounding like to me, so far, is that the human being (#1) would manually package the software (#2 and #3) external to Puppet, manually update the Puppet config, which would trigger Puppet to update the servers ... maybe? (I'm a little confused here, as I'm sure you can tell.) Thanks!

  • Poor performance on IIS7, only on Windows Server 2008, fine on Windows 7?

    - by user32005
    Hi, I'm new to IIS7 but have experience with other versions. I've been working on an application that works great in a dev environment (as always) but when I push it to a windows server 2008/IIS7 box performance takes a noticeable hit. The dev environment is Windows7/IIS7. The configuration in IIS is the same on the dev box as the server. I've tried all sorts of things to try and find a reason for this but I cant come to any conclusion. I've ruled out database problems on the live box as all data is cached after the first request. I've confirmed this to be true and made sure there is no additional database traffic. I've ruled out network issues with a combination of monitoring requests with fiddler and local debugging on the server. Whenever the code runs on the server there seems to be a performance issue. The server: Intel Core 2 Quad CPU Q6600 @ 2.40ghz with 2gb RAM. I know this is not fantastic but I was expecting it to at least perform as well as my dev environment (which is running much more on a lower spec). The CPU using peaks at under 60%, and memory usage is less than half of the available. I've enabled failed request tracing and most of the time is spent in a custom HttpModule, this module works to handle every request, I cant get any more detail as to what within the module may be causing the problem. Any ideas, I've been pulling my hair out for days now. Thanks

  • Windows 7 starts getting sluggish over a few days

    - by munrobasher
    Myself and the other developer are running Windows 7 Enterprise 64 bit with 8GB RAM on different Gigabyte motherboards with Quad core Intel CPUs. Most of the time, it runs like a dream. We use VMware workstation a lot (hence the 8GB) and that works well. Except... now and then, after the PCs have been on for a few days, the whole system starts getting really sluggish doing certain tasks. The other's developer's system is far worse than mine with it taking up to a minute to launch IE. Today, mine has gone sluggish but nowhere near as bad. For example, normally when I click on a new tab in IE, it's instant. Today, there's an obvious delay. Right-clicking in this window to trigger iSpell is normally instant, right now it takes about five seconds. I've got resource monitor open on my second monitor and when I did that right-click, there was no obvious peak in CPU, disk or memory. A reboot does fix it so it does sound like a resource issue but haven't a clue what might be to blame. The two computers have similarities (same spec) but also differences (like motherboard, RAM & CPU models). So I guess the question is, any pointers on diagnosing why a PC is sluggish? What could cause such a right-click slow down in IE for example? It sounds like such a simple operation. NOTE: whilst typing this message alone, it was fine performance wise. I can click around the page no problem but right-click still is noticeable slow. Will reboot over lunch... Cheers, Rob.

  • Configure IIS to pass-through CGI output without any conditioning

    - by Daniel Watrous
    I'm building a web service on Windows 2008 R2 with IIS 7.5 and Python 2.5. Right now I have the Handler Mappings and everything else setup just fine, Except that IIS is modifying what it gets back from the CGI script before sending it along the the client. Here's an example: I wrote the following CGI script: # hello.py print "Status: 400 Bad Request" print "Content-Type: text/html" print print "Error Message" According to the HTTP spec this should be fine and a Status of 400 should allow for a description of the error message in the body of the response. When the server response actually comes back to me I get the following: Status: 400 Bad Request Date: Fri, 11 Feb 2011 17:58:30 GMT X-Powered-By: ASP.NET Connection: close Content-Length: 11 Server: Microsoft-IIS/7.5 Content-Type: text/html Bad Request I've seen on this forum and others where I can change or eliminate the X-Powered-By header element, but I would like IIS to leave it alone altogether. I'm not sure why it takes my response, deletes "Error Message" from the body and replaces it with "Bad Request" and then adds all that other junk in. Is there some way to tell IIS to just send the response along without making any changes at all?

  • i7 Windows 7 laptop or Macbook Pro 15" (For making 3D model and Animation)

    - by sppdhs
    Hi everyone, I'm thinking of buying a new laptop as my current one will be 5 years old next year and it currently gives me a blue screen everytime I run a heavy software to make 3D models and animation. Question is: Should I buy Macbook Pro or a Windows 7 laptop? I tried to research and some say that Windows would be better, especially because you can buy a very high spec laptop with cheaper price. While some other say Macbook Pro is the better choice as it can run bootcamp with windows 7 100% performance on every software even though it's a mac. Is this true? Which one is actually better? Btw, the software that I usually use is 3Ds Max, Maya, and ZBrush. To note as well, I have never used a Mac before. I've checked around some stores and budget wise, I'll need around AU$3000+ to buy a Macbook pro, and AU$2000+ to buy a windows laptop. Quite a big difference in price range. Thanks in advance for your help.

  • ATI firepro will not detect a second DVI-D monitor

    - by John
    OK so weird issue here. I have previously been running 6 screens off of 3 of the older ATI firepro graphics cards but they had a problem with the heat sink getting too hot and warping the PCB resulting in total failure of the card, to replace my three dead cards I purchased a new-type ATI firepro with the newer heat sink design. I'm only using one at the moment to make sure they've fixed the problem before I waste more money on 2 more cards but this is where things start to get weird. The Firepro's only have one port on them, they connect to two monitors via a splitter cable going from the one port to two DVI connectors for the screens. When I plug two identical monitors in via their DVI inputs not matter what I do windows and Catalyst will only detect one screen. However if I use the VGA input on one of the screens with a VGA - DVI adaptor to plug it in to the card it works fine. This confuses me greatly. I'm currently using the ATI Firepro 2270 Graphics card with identical DELL U2311H screens. I can post the rest of the system spec as well if needed but I wouldn't have thought it would make much difference as it had no problem handling 6 screens before the graphics cards failed. Naturally both catalyst and ATI drivers are the most current version. ATI tech support has been absolutely zero help, they seemed to get stumped as soon as I verified that both screens were plugged in and connected properly. Anyone have any ideas?

  • JBoss https on port other than 8080 not working

    - by MilindaD
    We have a server with two JBoss instances where one runs on 8080, the other on 8081. We need to have HTTPS enabled for the 8081 server, firstly we tried enabling https on the 8080 port instance by generating the keystore and editing the server.xml and it successfully worked. However when we tried the same thing for 8081 it did not, note that we removed https for the 8080 server first before enabling it for 8081. This is what was used for both server.xml for 8080 and 8081. The only difference was that the port was changed from 8080 to 8081 when trying to enable https for 8081 port instance. What am I doing wrong and what needs to be changed? NOTE : When I meant enabled for 8080 I meant when you visit https:// URL:8484 you will actually be visiting the 8080 port instance. However when ssl is enabled for 8081 and I visit https:// URL:8484 I get that the web page is unavailable.

  • 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?

  • How can I avoid permission denied errors when attempting to deploy a rails app with capistrano?

    - by joshee
    Total noob here. I'm attempting to deploy an app through Capistrano. I'm getting relentless permission denied errors when I attempt to run cap deploy:update. Seemingly at least some of these errors are due to missing directories that trigger a "Permission Denied" error. (I'm doing setup on root just temporarily.) set :user, 'root' set :domain, 'domainname.com' set :application, 'appname' # adjust if you are using RVM, remove if you are not $:.unshift(File.expand_path('./lib', ENV['rvm_path'])) require "rvm/capistrano" set :rvm_ruby_string, '1.9.2' # file paths set :repository, "ssh://[email protected]/~/git/appname.git" set :deploy_to, "/var/rails/appname" # distribute your applications across servers (the instructions below put them # all on the same server, defined above as 'domain', adjust as necessary) role :app, domain role :web, domain role :db, domain, :primary => true set :deploy_via, :remote_cache set :scm, 'git' set :branch, 'master' set :scm_verbose, true set :use_sudo, false set :rails_env, :production namespace :deploy do desc "cause Passenger to initiate a restart" task :restart do run "touch #{current_path}/tmp/restart.txt" end desc "reload the database with seed data" task :seed do run "cd #{current_path}; rake db:seed RAILS_ENV=#{rails_env}" end end after "deploy:update_code", :bundle_install desc "install the necessary prerequisites" task :bundle_install, :roles => :app do run "cd #{release_path} && bundle install" end Here's my result: ** [domainname.com :: out] Cloning into '/var/rails/appname/shared/cached-copy'... ** [domainname.com :: err] Permission denied, please try again. ** [domainname.com :: err] Permission denied, please try again. ** [domainname.com :: err] Permission denied (publickey,gssapi-with-mic,password). ** [domainname.com :: err] fatal: The remote end hung up unexpectedly I'm able to ssh without a password, so not sure about that publickey error.

  • Move files from ftp server to s3

    - by lev
    I would like to set up an ftp server, where users will upload files, and for each file, put it on s3 storage, and delete it from the ftp server. (the server runs on ec2 ubuntu) Here are the stuff I already tried, with no success.. Mount s3 bucket using s3fs. I followed those instructions, but there is a bug in the latest version of s3fs, that prevents it from working. The bug was fixed on the develop branch, but I don't want to use unstable version on my production. Use vsftpd and using s3cmd sync via cron to sync the files periodically. The problem with that approach, is that s3cmd can start running in the middle of a file upload, and start synching the incomplete file. Also s3cmd doesn't give any feedback it the sync fails, so I have no way of knowing if I can delete the files after the sync command finished running. Use pure-ftpd's upload script feature (which allows to run a script after a file is finished uploading), but I noticed that if the file upload was failed in the middle, the script will run anyway, and I have no way of knowing if the upload was successful or not. I've been at it for a few days now, and I'm at a loss here. Any suggestions will be welcomed.

  • Reliable router with good VPN and WAN Throughput [closed]

    - by Asdande
    I have 2 cisco rv180 VPN router. These routers are giving me lots of problems. The webpages wont load correctly, slow response to load webpages plus other many issues. I have several cases pending with cisco. I give up on these routers. I would like to know if you guys can recommend me a reliable router for our 3 branches (NY - main, SC and FL). In NY- main office, we have 55 users. In SC branch, 6 users. In Florida we only have 1 (will grow soon). I need a router capable of support: 3 VPNs Site-to-Site connection VPN throughput of at least 40-50 Mbps WAN throughput at least 100 Mpbs and up PPTP Server for at least 5 PPTP users Web filtering - all users need access to internet Good Firewall Port forwarding for FTP Server - able to show the public IPs of FTP users (rv180 cannot do that, just shows me router's LAN interface IP, opened a case with cisco, now escaleted to level 2, still no answer or workaround) Dual WAN ports for balance or backup internet. Gigabit WAN/LAN ports Price between $400-$500 range. I was thinking on the TP-LINK TL-ER6120 or TL-ER6020 according to the review on smallnetbuilder.com http://www.smallnetbuilder.com/lanwan/lanwan-reviews/31983-tp-link-tl-er6020-safestream-gigabit-dual-wan-vpn-router-reviewed but I don't want to make another mistake as I did when I bought the cisco RV180. Thank you in advance,

  • Where do these mysterious DNS lookups come from and why are they slow?

    - by Hongli
    I have recently obtained a new dedicated server which I'm now setting up. It's running on 64-bit Debian 6.0. I have cloned a fairly large git repository (177 MB including working files) onto this server. Switching to a different branch is very very slow. On my laptop it takes 1-2 seconds, on this server it can take half a minute. After some investigation it turns out to be some kind of DNS timeout. Here's an exhibit from strace -s 128 git checkout release: stat("/etc/resolv.conf", {st_mode=S_IFREG|0644, st_size=132, ...}) = 0 socket(PF_INET, SOCK_DGRAM|SOCK_NONBLOCK, IPPROTO_IP) = 5 connect(5, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("213.133.99.99")}, 16) = 0 poll([{fd=5, events=POLLOUT}], 1, 0) = 1 ([{fd=5, revents=POLLOUT}]) sendto(5, "\235\333\1\0\0\1\0\0\0\0\0\0\35Debian-60-squeeze-64-minimal\n\17happyponies\3com\0\0\1\0\1", 67, MSG_NOSIGNAL, NULL, 0) = 67 poll([{fd=5, events=POLLIN}], 1, 5000) = 0 (Timeout) This snippet repeats several times per 'git checkout' call. My server's hostname was originally Debian-60-squeeze-64-minimal. I had changed it to shell.happyponies.com by running hostname shell.happyponies.com, editing /etc/hostname and rebooting the server. I don't understand the DNS protocol, but it looks like Git is trying to lookup the IP for Debian-60-squeeze-64-minimal as well as for happyponies.com. Why does Debian-60-squeeze-64-minimal come back even though I've already changed the host name? Why does Git perform DNS lookups at all? Why are these lookups so slow? I've already verified that all DNS servers in /etc/resolv.conf are up and responding slowly, yet Git's own lookups time out. Changing the host name back to Debian-60-squeeze-64-minimal seems to fix the slowness. Basically I just want to fix whatever DNS issues my server has because I'm sure they will cause more problems that just slowing down git checkout. But I'm not sure sure what the problem exactly is and what these symptoms mean.

  • Performance decrease in every game and application

    - by Márk Vincze
    When I start a game, initially it runs smoothly, but after a couple of minutes, the performance gradually decreases to the point of being unplayable (1-2 FPS). The sound also starts to lag at this point. This does not happen every time I start my PC, usually exiting the game, rebooting, then starting the game again solves the problem, and I can play with perfect FPS for as long as I want. I could not find any deterministic reason when this happens and when doesn't. It happens in every game I tried (SWTOR, Diablo 3, Skyrim), and not even games, but simple applications like a browser or the Control Panel can get unusably slow. This is a brand new PC I bought three months ago, and this problem occurs since the first day I've been using it. Could you provide any advice how to further diagnose the problem? I tried to reinstall Windows, and tried different video card drivers, but it did not help. It would be important to know whether this is a hardware or software problem, because I can use the warranty if it is a hardware issue. (I did not want to return the PC yet, because I can't reproduce the issue deterministically.) Spec of the pc: Motherboard: ASROCK H61M-HVS CPU: INTEL Core i3-2120 3.30GHz 1155 BOX Memory: KINGMAX 4096MB DDR3 1333MHz KIT Video card: GIGABYTE GV-R685OC-1GD HD6850 1GB GDDR5 PCIE HDD: SEAGATE 500GB Barracuda 7200rpm 16MB SATA3 ST500DM002 I am using Windows 7 64 bit.

  • Gaming blew fuse: how to overcome?

    - by George Tomlinson
    I've been gaming for a while now. When playing certain games this PC goes into overdrive. The fan/fans start/s to sound like a jet engine it/they get/s so busy. Also I have smelt burning when this has happened. The fuse blew on the 4 socket adapter I was using recently. On the following thread someone said this could be due to the PSU not being strong enough to handle the load, in what it seems could be a related issue someone had, although the person who posted this question did say that blowing a fan on their PC stopped it crashing in that case: http://www.tomshardware.co.uk/answers/id-2047543/gtx-650-overheating-issue.html. This is exactly what they said: Your GPU isn't overheating. 70+ before it would shutdown and cause a restart. Make sure your PSU is strong enough to handle your new system at load and possibly run Memtest to check your RAM (although not BSOD'ing and just shutting down points to the PSU). This (the PSU part) makes more sense to me than it being to do with dust etc, since it seems a more plausible explanation of why the fuse blew. The PC has no problems except when playing certain games: i.e. TERA Rising and WoW with add-ons (I think WoW is ok as long as I don't have more than 1 add-on (Healers Have To Die)). I'm just wondering if anyone knows or can suggest what I might be able to do to be able to play these games without this problem occurring. The PC's spec is this: Display: NVIDIA GeForce GTX 650 8GB RAM (6 available) Processor: AMD FX (tm) - 8120 Eight-Core Processor - 3.1 GHz, 4 Cores, 8 Logical Processors I have read on another post that forcing vsync in the Nvidia Control Panel helped with what seems could be a similar problem, so I plan to see if that solves it, God permitting.

  • SSH does not allow the use of a key with group readable permissions

    - by scjr
    I have a development git server that deploys to a live server when the live branch is pushed to. Every user has their own login and therefore the post-receive hook which does the live deployment is run under their own user. Because I don't want to have to maintain the users public keys as authorized keys on the remote live server I have made up a set of keys that 'belong's to the git system to add to remote live servers (In the post-receive hook I am using $GIT_SSH to set the private key with the -i option). My problem is that because of all the users might want to deploy to live, the git system's private key has to be at least group readable and SSH really doesn't like this. Here's a sample of the error: XXXX@XXXX /srv/git/identity % ssh -i id_rsa XXXXX@XXXXX @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: UNPROTECTED PRIVATE KEY FILE! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Permissions 0640 for 'id_rsa' are too open. It is required that your private key files are NOT accessible by others. This private key will be ignored. bad permissions: ignore key: id_rsa I've looked around expecting to find something in the way of forcing ssh to just go through with the connection but I've found nothing but people blindly saying that you just shouldn't allow access to anything but a single user.

  • Half of installed RAM is hardware reserved

    - by user968270
    After a rather arduous and convoluted series of problems that left me without a desktop for ~80 days, I've finally got the thing up and running, having replaced the power supply, motherboard, graphics card and CPU. Now, however, I'm experiencing the 'hardware reserved RAM' issue. Perhaps this is the exhaustion talking, but looking at the question that tends to get pointed to when this kind of topic gets locked as a duplicate hasn't helped. I have 16 GB of RAM installed in an MSi 970A-G46, which is spec'd for up to 32 GB of RAM. The BIOS recognizes that I have 16 GB installed, and the resource monitor also shows the whole 16 GB, only it shows 8 GB as hardware reserved. I've seen suggestions that it's an OS issue, but the particular installation of Windows 7 (64-bit) which I'm running on my boot drive is the same as the one that could actually access the 16 GB in my previous motherboard (MSi 870A-G54). I've updated my BIOS using the MSi Live Update tool and restarted the machine with no effect, and I cannot seem to locate any 'Memory Remapping' option as I've seen mentioned. I've physically swapped the RAM between the slots to no effect. I've unchecked the Maximum Memory box in the msconfig Boot tab's advanced options, also to no effect. These are my system's basic specifications OS: Windows 7 Home Premium (64-Bit) Motherboard: MSi 970A-G46 CPU: AMD FX-8150 Graphics Card: XFX Radeon HD 6870 Boot Drive: OCZ Agility 3 Storage Drive: Samsung Spinpoint F3 ST1000DM005/HD103SJ 1TB PSU: Thermaltake TR-2 TR600 600W ATX12V v2.3

  • Extracting information from active directory

    - by Nop at NaDa
    I work in the IT support department of a branch of a huge company. I have to take care of a database with all the users, computers, etc. I'm trying to find a way to automatically update the database as much as possible, but the IT infrastructure guys doesn't give me enough privileges to use Active Directory in order to dump the users, nor they have the time to give me the information that I need. Some days ago I found Active Directory explorer from Sysinternals that allows me to browse through Active Directory, and I found all the information that I need there (username, real name, date when it was created, privileges, company, etc.). Unfortunately I'm unable to export the data to a human readable format. I'm just able to take a snapshot of the whole database in a machine-readable format. Doing the snapshot takes hours and I'm afraid that the infrastructure guys won't like me doing entire snapshots on a regular basis. Do you know of any tool (command-line is preferable) that would allow me to retrieve the values of the keys or export it to XML, CSV, etc?

  • Trying to delete a directory stored on a Windows server, from on a Mac, containing files created on the Mac, getting "Directory not empty"

    - by AdamG
    I am trying to delete a directory stored on a Windows 2008 R2 server, mounted on a Mac as network home (10.8.5). The directory was created by Safari and stores temporary internet files. I need to be able to delete this folder on logout from a Mac bash script. The Terminal on Mac shows the directory as empty: 36W-FacRm-02:History lwickham$ cd /home/lwickham/Library/Caches/Metadata/Safari/History 36W-FacRm-02:History lwickham$ ls -al total 0 drwx------ 1 lwickham CGPS\Domain Users 264 Nov 8 09:24 . drwx------ 1 lwickham CGPS\Domain Users 264 Nov 8 09:28 ..

  • Cannot get at data in my NAS

    - by Ben
    I've got a bit of an issue that I'm hoping you can help me with. I have an Iomega ix4 as my NAS. This runs Linux and each drive in the box has 2 partitions: one for the OS and RAID info, and the second for the actual data. I had it configured as RAID5. Recently one of the drives failed. At this point all of the data was available, it was just reporting a failed drive. I had a drive of the same capacity (although not the exact same spec) which I swapped in place of the failed drive. It recognised it, and started to rebuild the data protection. So far so good ... or so I thought. The next day, after data protection had finished reconstructing, the NAS was telling me that 4 new drives had been added, and wanted confirmation to overwrite the data. Obviously I declined to do this. I swapped the failed drive back in again, in the hope that it would return to its previous state of the data being accessible, but one failed disk. However it didn't - it still tells me that the NAS has 4 new drives in it. I am hopeful that the actual data is untouched, so what I need to do is get it to rebuild the RAID without touching the data on the disks. I have ssh access, and have run stuff like mdadm --examine to see what I can find. The mdadm.conf file has no entry in the "definitions of existing MD arrays" section. I have not run any actual rebuilding commands as yet, because this is entering an area which I am out of my depth in. Please can someone advise the best way of getting my data? Thanks.

  • cheap gigabit switch for small business

    - by neoice
    my friend's business is currently borrowing my Adtran 1224R and is very happy with it. it's configured with a few VLANs to segment customers, internal traffic and public wifi. port 1 is a "trunk" port to the router, a chunky Linux box with iptables+NAT. they push a lot of traffic over the LAN (data backups) and really need gigabit. besides, I'd like my Adtran back :P my goal is to find a cheap(ish) switch that can function as a drop-in replacement. it looks like VLAN trunking is actually part of the 802.1q spec, so anything with VLAN support should cover the current trunk-to-router setup. it's nice to have both a web interface and SSH, but I can configure it either way if needed. things like the Netgear GS724T have caught my eye, but it seems like none of the hardware in the $300-500 range have really solid reviews. I'm concerned that "cheaper" hardware might not work for a network full of power users. does anyone have a recommendation for the Netgear GS724T or a switch that will meet my needs?

  • USB 3.0 ports backwards compatibility problems with 2.0 devices?

    - by AaronLS
    I see some info on the net that suggest that I should be able to get my USB 2.0 devices to work in 3.0 ports. I only have two 2.0 ports on my new computer, and six 3.0 ports. I have installed drives. There's two different drivers, I guess some of the ports are supported by the intel board and some supported by some other chipset on the motherboard. I however have yet to get any of the 3.0 ports to work, and my brother had had the same issue with his devices not working in 3.0 ports on his computer. So I am beginning to wonder if the backwards compatibility isn't reliable for some reason. Maybe manufacturers opting not to implement 2.0 support on the 3.0 ports. I understand that physically the wiring is there, but that is only half the story. Beyond my brother's and my own computers (different motherboards/everything), I have yet to see a 2.0 device work in a 3.0 port. Is there any reason for this apparent device incompatibility? I.e. looking for responses that would indicate what areas to explore for issues or if there is any known cases of manufacturers deviating from spec in hardware or drivers. I am aware it's "supposed" to work :) Update: Does this have any relation to "USB Legacy Support" options in the BIOS? There several options combinations of options with "USB Legacy Support" and "USB 3.0 Legacy Support" and the description for these is a bit confusing, sounds like a bad translation.

  • apache/httpd responds slower under EL6.1 than EL5.6 (centos)

    - by daniel
    I've read through other threads on performance differences between RHEL6 and RHEL5, but none seem a tight match to mine. My issue manifests itself in slightly slower average response time (20ms) per request. I have about 10/10 servers of the same hardware spec with Cent6.1 and Cent5.6. The issue is consistent across the group. I am running Ruby on Rails with Passenger. Apache config is identical (checked out from the same SVN repo) Ruby and Passenger are identical builds. Application is identical and being served traffic round robin. mod_worker An interesting clue from server-status: The Cent6.1 servers have a steady 20-40 threads in the "Reading Request" state while the Cent5.6 servers have around 1. I'm graphing this so I can see it trend over time. I also have a bunch of much newer machines that are significantly faster and are running Cent6.1. They dust all the older machines in response time, but I can see they also have a steady 20-40 threads in the "Reading Request" state. This makes me believe I can get their response time down, if I can figure out what is holding up these requests. My gut is telling me that I need to tune some network setting in sysctl, but I haven't figured it out yet. Help is appreciated.

  • What is the typical maximum number of database connections for Oracle running on Windows server ?

    - by Sake
    We are maintaining a database server that serve a large number of clients. Each client typically running serveral client-applications. The total number of connections to the database server (Oracle 9i) is reaching 800 connections on peak load. The windows 2003 server is starting to run out of memory. We are now planning to move to 64bit Windows in order to gain higher memory capability. As a developer I suggest moving to multi-tier architecture with conneciton pooling, which I believe is a natural solution to this problem. However, in order to support my idea, I want the information on: what exactly is the typical number of connections allowed for Oracle database ? What is the problem when the number connections is too high ? Too much memory comsumption ? or too many sockets opened ? or too many context switching between threads ? To be a little bit specific, how could Oracle Forms application scale to thousand of users without facing this problem ? Shall Oracle RAC applied to this case ? I'm sure the answer to this question should depend on quite a number of factors, like the exact spec of the hardware being used. I'm expecting a rough estimation or some experience from the real world.

  • Suggestions for transitioning to new GW/private network

    - by Quinten
    I am replacing a private T1 link with a new firewall device with an ipsec tunnel for a branch office. I am trying to figure out the right way to transition folks at the new site over to the new connection, so that they default to using the much faster tunnel. Existing network: 192.168.254.0/24, gw 192.168.254.253 (Cisco router plugged in to private t1) Test network I have been using with ipsec tunnel: 192.168.1.0/24, gw 192.168.1.1 (pfsense fw plugged in to public internet), also plugged in to same switch as the old network. There are probably ~20-30 network devices in the existing subnet, about 5 with static IPs. The remote endpoint is already the firewall--I can't set up redundant links to the existing subnet. In other words, as soon as I change the tunnel configuration to point to 192.168.254.0/24, all devices in the existing subnet will stop working because they point to the wrong gateway. I'd like some ability to do this slowly--such that I can move over a few clients and verify the stability of the new link before moving critical services or less tolerant users over. What's the right way to do this? Change the netmask on all of the devices to /16, and update gateway to point to the new device? Could this cause any problems? Also, how should I handle DNS? The pfsense box is not aware of my Active Directory environment. But if I change DNS to use the local servers, it will result in a huge slowdown as DNS queries will still be routed over the private t1. I need some help coming up with a plan that's not too disruptive but will really let me thoroughly test the stability of the IPSEC tunnel before I make the final switch. The AD version is 2008R2, as are the servers. Workstations are mostly Windows XP SP3. I have not configured the 192.168.1.0/24 as a site in AD sites and services.
