• AMD FX8350 CPU - CoolerMaster Silencio 650 Case - New Water Cooling System

  - by fat_mike

  Lately after a use of 6 months of my AMD FX8350 CPU I'm experiencing high temperatures and loud noise coming from the CPU fan(I set that in order to keep it cooler). I decided to replace the stock fan with a water cooling system in order to keep my CPU quite and cool and add one or two more case fans too. Here is my case's airflow diagram: http://www.coolermaster.com/microsite/silencio_650/Airflow.html My configuration now is: 2x120mm intake front(stock with case) 1x120mm exhaust rear(stock with case) 1 CPU stock I'm planning to buy Corsair Hydro Series H100i(www.corsair.com/en-us/hydro-series-h100i-extreme-performance-liquid-cpu-cooler) and place the radiator in the front of my case(intake) and add an 120mm bottom intake and/or an 140mm top exhaust fan. My CPU lies near the top of the MO. Is it a good practice to have a water-cooling system that takes air in? As you can see here the front of the case is made of aluminum. Can the fresh air go in? Does it even fit? If not, is it wiser to get Corsair Hydro Series H80i (www.corsair.com/en-us/hydro-series-h80i-high-performance-liquid-cpu-cooler) and place the radiator on top of my case(exhaust) and keep the front 2x120mm stock and add one more as intake on bottom. If you have any other idea let me know. Thank you. EDIT: The CPU fan running ~3000rpm and temp is around 40~43C on idle and save energy. When temp is going over 55C when running multiple programs and servers on localhost(tomcat, wamp) rpm is around 5500 and loud! I'm running Win8.1 CPU not overclocked PS: Due to my reputation i couldn't post the links that was necessary. I will edit ASAP.

• django, mod_wsgi, MySQL High CPU - Problems

  - by Red Rover

  Good Evening, and thank you for reading this post. I am having a problem with Django after migrating the dB from SQLlite to MySQL. Initially, for the first 48hours, all ran well. But now we are experiencing high cpu about every 30 minutes. This is a production ESX4i VM host, with 2 x 2.8 ghz CPUs and 12 GB ram. I have allocated 4 cpu's to this VM and 4 GB memory. Any insight into this configuration and help with the spikes in CPU would be appreciated. IT is configured to use the prefork MPM. Outlined are the config's for the different services: MySQL Server version: 5.1.61 Source distribution Django 1.3 mod_wsgi Apache/2.2.15 httpd.conf Timeout 120 KeepAlive Off MaxKeepAliveRequests 400 KeepAliveTimeout 3 prefork MPM StartServers 8 MinSpareServers 8 MaxSpareServers 16 ServerLimit 40 MaxClients 40 MaxRequestsPerChild 0 worker MPM StartServers 16 MaxClients 1024 MinSpareThreads 64 MaxSpareThreads 256 ThreadsPerChild 64 MaxRequestsPerChild 10240 MySQL my.conf [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql symbolic-links=0 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid my.cnf wsgi.conf LoadModule wsgi_module modules/mod_wsgi.so /etc/httpd/conf.d/wsgi.conf WSGISocketPrefix /var/run/wsgi WSGIPythonEggs /var/tmp WSGIDaemonProcess SITE maximum-requests=10000 WSGIProcessGroup SITE

• htaccess not properly rewriting urls

  - by Cameron Ball

  This is a bit of a weird one. I'm doing some work on a server, and I need rewrite rules for directories that actually exist (in some cases, they are more than one level deep) At the moment my .htaccess looks like this: RewriteEngine on RewriteRule ^simfiles/([-\ a-zA-Z0-9:/]+)$ http://mydomain.com/?portal=simfiles&folder=$1 [L] And this is working OK, for example, a url like: mydomain.com/sifmiles/my-files Will get redirected to mydomain.com/?portal=simfiles&folder=my-files Or in the case of a directory structure that is deeper than one level: mydomain.com/sifmiles/my-files/more-of-my-files Will get redirected to mydomain.com/?portal=simfiles&folder=my-files/more-of-my-files I wrote the regex so that it won't match things with a . in the path, because there are css and js files which reside in simfiles/somedirectory, and if I redirect everything then these cannot be loaded. I tried a configuration like this: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^simfiles/([-\ a-zA-Z0-9:/\.]+)$ http://mydomain.com/?portal=simfiles&folder=$1 [L] But that doesn't work, things still don't load properly. So my first question is, how can I achieve this "properly"? I don't like my solution because it means redirects won't occur if the folder has a . in its name. My second problem, is that while the redirection is happening properly, the url becomes: http://mydomain.com/?portal=simfiles&folder=my-files I want the URL to remain clean, like: http://mydomain.com/sifmiles/my-files How can I achieve this?

• Windows Media Player 12 Library import keeps dying

  - by duckworth

  I cannot get WMP 12 to import my library. I have searched around various forums and tried all the common solutions like disabling Media Sharing, deleted my %LOCALAPPDATA%\Microsoft\Media Player directory and tried reimporting, etc. but nothing works. I have even removed the Media features from Windows setup and re-added them. I have a large mp3 collection shared on the network from another Windows box. I add the folder (tried as a mapped drive and UNC path) and it begins importing. After about 30 minutes into the import (the CurrentDatabase_372.wmdb hits just under 400MB) my WMP player stops importing and all of the icons in WMP turn to red x's and my library is gone. I close and reopen WMP 12 and the library is empty and the CurrentDatabase_372.wmdb is small and it strarts importing again. Rinse, lather, repeat. I am going nuts as WMP11 on Vista handles this same setup perfectly. I am at my wits end on what else to try. I am running a legit Windows 7 Ultimate X64 RTM install. Here is a screenshot of what WMP12 looks like when the import dies: Any other ideas? Edit: OK, I Just confirmed this is definitely a problem not specific to my computer or configuration. I just did a clean installation of Windows 7 Ultimate x86 on an old test machine, opened WMP12 and added the same network folder of mp3's and it crashed about an hour into the import with the same appearance as the screenshot I posted above and the library disappears. So the problem has to be one of several things: The large size of the library The fact that the library is on the network A specific file or file is causing it the player to crash

• Postfix: change sender in queued messages

  - by ring0

  Following a complete re-installation we got a problem with the configuration: the sender address was wrong and some recipients (mail servers) rejected them. So there is a bunch of mails stuck in the Postfix queue. Ideally, a change of the sender address directly in the queued mails, and then flushing the queue would be optimal. I tried this answer that addresses this very problem. But messages don't seem to be easily modifiable in the version I have (2.11.0). For instance there is no /var/spool/mqueue dir, but, instead, /var/spool/postfix/... active bounce corrupt defer deferred dev etc flush hold incoming lib maildrop pid private public saved trace usr and the dir of interest is deferred. I tried to modify a few files there changing the wrong domain with the correct one (and was careful to ensure only those were changed). But then, those mails were moved to corrupt, meaning that a simple text change doesn't seem to work (done with vi). Any other cleaner way to change the sender in queued mails?

• Windows 7 Black Screen On Boot, Seperate Bootable VHD Works Fine

  - by David Osborn

  I have a Window 7 x64 install with a bootable VHD (also Windows 7 x64). I was having problems getting my homeserver to do backups (VSS erred) so I ran check disk and used a tool from MS (cleanc2r.exe) to remove an empty Q drive from the VHD that I believe was a result of installing Office 2010 Beta. (All of this was done on the bootable VHD, not the main install.) Now I can't boot into the main install. It gets past the Starting Windows screen and then goes black. I can still boot into the bootable VHD and everything works fine from there. I have tried to boot the main install in Safe Mode/Safe Mode with Networking/and Safe Mode command prompt and it has the same issue. I ran chkdsk /r on the main install and after doing all the work there was a message about correcting some free space that was marked as allocated and also that it was unable to make an entry into the event log. I tried the startup repair utility and it found no problems. I don't see the setting for restore to last know good configuration so I couldn't do that. I don't recall installing anything new to the main install nor having hooked up any new hardware recently.

• A complicated nginx/php-fpm chroot setup

  - by Rsaesha

  I'm running nginx and php-fpm, and I want to set up jails for each host. My setup is a little complicated, so following tutorials on the web gets me nowhere. Each site has a directory /var/www/domain.name/ Inside that directory, there will be a public/ directory which will be the website root, a logs/ directory which will store nginx logs for that site specifically, and the chroot filesystem (etc/, usr/, etc.) The first problem I've run into is that nomatter how I configure it, PHP-FPM cannot find the files that are passed to it via nginx. They result in a "Primary script unknown" error, and to make matters worse, the error messages from PHP-FPM are no more verbose than that, so I can't figure out what path is being passed by nginx. A php-fpm pool configuration for a host looks like this: [host] user = host group = www-data chroot = /var/www/domain.name chdir = /public listen = 127.0.0.1:900x 'x' is incremented for each pool. The nginx config for this host looks like this: server { listen 80; server_name domain.name *.domain.name; root /var/www/domain.name/public; index index.php index.html index.html; location ~ \.php$ { expires epoch; fastcgi_split_path_info ^(.+\.php)(/.+)$; include fastcgi_params; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_pass 127.0.0.1:9001; } } I'm guessing that the problem is the SCRIPT_FILENAME parameter, but I've changed it to just $fastcgi_script_name, and various other combinations, but to no avail. Can anyone help?

• Cannot set up dual monitors correctly in Fedora15 with KDE.

  - by adivasile

  I have 2 monitors: 24" LCD connected via DVI(primary) 19" LCD connected via VGA(secondary) Everytime Fedora starts the second display is always set to clone the first one and they both run at 1280x1024 and I always have to disable the 19" monitor, in order for the bigger one to run at 1920x1080. I want to set them up so that my secondary monitor extends the primary one.The problem is that no matter what kind of configuration I choose it has no effect.My secondary monitor remains disabled. I've tried using both the Display manager from KDE and the ATI Control Panel and the behaviour is always the same.The moment I click apply, the screen flickers and nothing changes. I've succesfully used the extended setup in Fedora15 with Gnome3. I have a RadeonHD 4300 series videocard and I'm using the drivers downloaded from the AMD site. This is the output of xrandr -q : Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 1920 x 1920 VGA-0 connected (normal left inverted right x axis y axis) 1280x1024 75.0 60.0 1280x960 60.0 1152x864 75.0 1024x768 75.0 70.1 66.0 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 75.0 72.8 66.7 59.9 720x400 70.1 DVI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 60.0 1680x1050 59.9 1600x900 60.0 1280x1024 75.0 60.0 1280x960 60.0 1152x864 75.0 1280x720 60.0 1152x720 60.0 1024x768 75.0 60.0 832x624 74.6 800x600 75.0 60.3 640x480 75.0 59.9 720x400 70.1 Later edit: The problem seems to come from the ATI drivers.I managed to set up the monitors like I wanted after I uninstalled the drivers. Unfortunately I'm working on an OpenCL project so I had to reinstall them.The moment I did that, all my previous settings were forgotten and I was back to square one.

• What can lead to a zone memory exhaustion and how Nginx reacts to it?

  - by Miles Hughes

  What is a possible scenario for exhausting the memory designated to a connection zone with limit_conn_zone directive and what are the implication in this case? Suppose I have this in my configuration: http { limit_conn_zone $binary_remote_addr zone=connzone:1m; ... server { limit_conn connzone 5; which, according to the documentation, allocates 16000 states for connzone on a 64-bit server. It also says that If the storage for a zone is exhausted, the server will return error 503 (Service Temporarily Unavailable) to all further requests. Well, Ok. But what does it mean on practice? When does this happen? Who receives those 503s? Does it mean that if the number of IPs somehow associated with connzone hits 16000 everyone gets a 503 and it's all over? How does Nginx decide? The documentation is weirdly vague on this. So, considering the example config, who would actually get a 503 and under which circumstances and how would things go from there? Same with request zones?

• can't access SATA card config screen on boot, nor access the disks

  - by Ronald

  We've just upgraded our file server using an ASUS P6T WS Pro board, running FreeBSD-RELEASE 8.2 and using zfs to manage 12 WD20EARS disks. Since our 3ware card has been giving us trouble we started using the six on-board SATA connectors and got a SuperMicro USAS2-L8i to provide eight more ports. Mechanically, the card is an awkward fit but electrically it all seems ok. Upon boot, the LSI controller shows up and states that pressing ctrl-c will bring up the LSI Config Utility. When doing that, the message changes to state that the utility will be started after initialization, however that never happens. There does seem to be an error message that's only displayed too briefly to read and seems to be about PCI and "not enough space". (That message is pushed off by a hardware summary and I've found no way to scroll back at this point.) The disks do not show up in any recognizable ways after booting, either. I found a hint in another discussion to check the address mapping on either the card or the motherboard BIOS, but have found no way to do that. So what I tried on a hunch is to disable everything that's on-board, including network adapters, Firewire controller and SATA. In fact, after doing that, I can successfully launch the LSI Config Utility. As far as I can tell, all looks well in there, and when booting in that configuration it also displays a list of the disks connected to it, which looks just fine as well. Only problem now is that I can't boot that way, because I need the on-board SATA controller and network adapters. As soon as I re-enable any of them I'm back to square one. That discussion I mentioned about mapping addresses said to try D000, then D7FF, then DFFF, in order. The LSI Config Utility shows the card address as D000 but offers no way of changing it. Any tips or insights would be appreciated.

• Display stretches 4:3 ratios; Adds scrolling to other ratios

  - by Matt

  I have a dual monitor setup. Normally, they both display at 1680x1050. They have been setup this way for about a year. I'm using Windows XP Professional 2003 x64 SP2. Today, out of nowhere, one of the monitors kicked back to a lower resolution. I was not playing with any configuration at the time.. in fact all I had done was close a window (maybe a browser). But the thing is that the resolution is still preserved partially by the fact that the screen will scroll when you move the mouse. So it's like looking through a 1024x768 window into a 1680x1050 world. The monitor itself does not appear to be damaged, because I also have it connected to my netbook (via KVM) and higher resolutions work fine. I tried uninstalling/reinstalling the drivers to no avail. System restore doesn't help either. I'm unsure of the exact ATI card I'm using.. Device Manager lists it as "Radeon X300/X550/X1050". There is no Catalyst Control Center software installed. I tried to install it, but there doesn't seem to be a way to install it by itself ... it forces you to install another driver, which breaks both of my displays, forcing me to go into safe mode and run system restore again. Any ideas? Thanks EDIT: After playing around more, I discovered that the "scrolling" behavior is only present for aspect ratios that are not 4:3. For 4:3 ratios, it just stretches out to fit the wide screen. My monitor's native ratio is 16:9 .. what could be causing it to think it needs to scroll?

• Nexus 1000v VEM fails on 2 out of 8 hosts.

  - by cougar694u

  I have 8 ESXi hosts. I do a fresh install from the installable CD directly to 4u1. We have another 2-node cluster with a working Nexus 1000v primary & secondary. Everything's up and running. I installed 6 hosts and everything worked great, migrated them to the Nexus DVS, and VUM installed the modules. I did the 7th host, and when I tried to migrate it to the DVS, it failed with the following error: Cannot complete a Distributed Virtual Switch operation for one or more host memebers. DVS Operation failed on host , error durring the configuration of the host: create dvswitch failed with the following error message: SysinfoException: Node (VSI_NODE_net_create) ; Status(bad0003)= Not found ; Message = Instance(0): Inpute(3) DvsPortset-0 256 cisco_nexus_1000v got (vim.fault.PlatformConfigFault) exception Then, I tried to do host 8, and got the exact same problem. It worked about 15 minutes prior when I did host 6, nothing changed, then went to host 7 and it failed. If I try to remediate either of these two hosts, either patches or extensions, it fails. Anyone else have these problems?

• How can I explain to dspam that the user "brandon" is the same as "brandon@mydomain"

  - by Brandon Craig Rhodes

  I am using dspam for spam filtering by running the "dspamd" daemon under Ubuntu 9.10 and then setting up a Postfix rule that says: smtpd_recipient_restrictions = ... check_client_access pcre:/etc/postfix/dspam_everything ... where that PCRE map looks like this: /./ FILTER lmtp:[127.0.0.1]:11124 This works well, and means that all users on my system get all of their email, whether "dspam" thinks it is innocent or not, and have the option of filtering on its decisions or ignoring them. The problem comes when I want to train dspam using my email archives. After reading about the "dspam" command, I tried this on the files in my Inbox and spam boxes (which date from when I was using another filtering solution): for file in Mail/Inbox/*; do cat $file | dspam --class=innocent --source=corpus; done for file in Mail/spam/*; do cat $file | dspam --class=spam --source=corpus; done The symptom I noticed after doing all of this was that dspam was horrible at classifying spam — it couldn't find any! The problem, when I tracked it down, was that I was training the user "brandon" with the above commands, but the incoming email was instead compared against the username "brandon@mydomain", so it was running against a completely empty training database! So, what can I do to make the above commands actually train my fully-qualified email address rather than my bare username? I would like to avoid having to run "dspam" as root with a "--user" option. I would have expected that the "dspam" configuration files would have had an "append_domain" attribute or something with which to decorate local usernames with an appropriate email domain, but I can't find any such thing. When I used to use the Berkeley DB backend to "dspam", I solved this problem by creating a symlink from one of the databases to the other. :-) But that solution eventually died because the BDB backend is not thread-safe, so now I have moved to the PostgreSQL back-end and need a way to solve the problem there. And, no, the table where it keeps usernames has a UNIQUE constraint that prevents me from listing both usernames as mapping to the same ID. :-)

• Understanding what needs to be in place for a server to send outgoing email from a linux box

  - by Matt

  I am attempting to configure an openSuse 11.1 box to send outgoing email for a domain that the same server is hosting. I don't understand enough about smtp servers and the like to know what needs to be in place and working. The system already had Postfix installed, and I confirmed it was running via a > sudo /etc/init.d/postfix status I examined the Postfix config file in /etc/main.cf and configured a couple of items regarding the domain/host name and such, but left it largely default. I attempted to send an email from the command line with the following command: > echo "test 123" | mail -s "test subject" [email protected] Where differentdomain.com was not the same domain as the one best hosted on the server. However, the email never reaches the target account. Any suggestions? EDIT: In the postfix log, (/var/log/mail.info, there's nothing in .err) I see that postfix is trying to connect to what appears to be a different smtp server on our network, with a connection refused: connect to ourdomain.com.inbound15.mxlogic.net[our ip address]:25: Connection refused However, I can't figure out why it is 1) trying to connect to that server and 2) not just sending the messages itself... I mean, isn't postfix an smtp server? I did a grep -ri on ourdomain from /etc and see no configuration files anywhere telling it to do this. Why is it?

• Postfix aliases and duplicate e-mails, how to fix?

  - by macke

  I have aliases set up in postfix, such as the following: [email protected]: [email protected], [email protected] ... When an email is sent to [email protected], and any of the recipients in that alias is cc:ed which is quite common (ie: "Reply all"), the e-mail is delivered in duplicates. For instance, if an e-mail is sent to [email protected] and [email protected] is cc:ed, it'll get delivered twice. According to the Postfix FAQ, this is by design as Postfix sends e-mail in parallel without expanding the groups, which makes it faster than sendmail. Now that's all fine and dandy, but is it possible to configure Postfix to actually remove duplicate recipients before sending the e-mail? I've found a lot of posts from people all over the net that has the same problem, but I have yet to find an answer. If this is not possible to do in Postfix, is it possible to do it somewhere on the way? I've tried educating my users, but it's rather futile I'm afraid... I'm running postfix on Mac OS X Server 10.6, amavis is set as content_filter and dovecot is set as mailbox_command. I've tried setting up procmail as a content_filter for smtp delivery (as per the suggestion below), but I can't seem to get it right. For various reasons, I can't replace the standard OS X configuration, meaning postfix, amavis and dovecot stay put. I can however add to it if I wish.

• Server 2008 R2 DNS Lockup / Stops Resolving Internet Names

  - by Richard Maynard

  We've deployed our first 2008 R2 server on a client site which has replaced their existing 2003 DC. This server provides DNS resolution services to all client machines on that site for general internet usage. Since using the 2008 R2 DNS services we have noticed every couple of days the DNS server starts timing out when requests to certain sites are made (google is the only example I can provide at this time although it seems to be larger sites with problems rather than small - CDN compatiblity issue?). When you restart the DNS Server service then resolution returns to normal... just only for a day or so. Is anybody aware of any significant changes to the DNS server architecture or configuration out of the box in R2 that may explain this intermittent behaviour? I have already tried the fix listed here to no avail: http://weblogs.asp.net/owscott/archive/2009/09/15/windows-server-2008-r2-dns-issues.aspx The following PS command prompt info illustrates the issue: PS C:\Users\Administrator.UK> nslookup Default Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 > www.google.com Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 Non-authoritative answer: Name: www.l.google.com Addresses: 66.102.9.99 66.102.9.104 66.102.9.105 66.102.9.103 66.102.9.147 Aliases: www.google.com > www.google.co.uk Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 * s8209001.uk.kingdomfaith.com can't find www.google.co.uk: Server failed

• Force SSL on one page via .htaccess without looping

  - by Will Martin

  Okay, I have this code: RewriteCond %{HTTPS} off RewriteCond %{REQUEST_URI} ^/borrowing/ill/request\.php$ RewriteRule ^.*$ https://%{HTTP_HOST}%{REQUEST_URI} [R,L] The way I would expect this to work is: A request for /borrowing/ill/request.php comes in on HTTP. The rule matches. The server redirects to HTTPS. The rule does not match, because HTTPS is now on. The way it actually works is: A request for /borrowing/ill/request.php comes in on HTTP. The rule matches. The server redirects to HTTPS. The rule matches. The server redirects to HTTPS. The rule matches. The server redirects to HTTPS ... And so on. I know that the second condition (matching the file name) is working, because the redirect loop only hits that specific page. The question is, why isn't the switch to HTTPS causing the first condition to not match? EDIT: I put the exact same .htaccess rules into a test area on another server -- same file and path info. And they worked just fine. There's got to be something wrong with the server configuration elsewhere.

• Does WebDAV even work on IIS 7? I say nay

  - by FlavorScape

  I've tried every configuration from the top 10 stack overflow and server fault results for WebDAV 405 on IIS (for verb PROPFIND and PUT). I'm running server 2008 SP2. Followed all the instructions here. I'm no stranger to configuring servers. This has gotten nowhere after 8 hours. Confirmed system.webserver in applicationhost.config: <add name="WebDAV" path="*" verb="PROPFIND,PROPPATCH,MKCOL,PUT,COPY,DELETE,MOVE,LOCK,UNLOCK" modules="WebDAVModule" resourceType="Unspecified" requireAccess="None" /> Port 443 with basic auth, same issue. Tried port 80 with windows auth. Broken. (405) Windows authentication. Check. Added authoring rules for default site and application. Check. Not the firewall. Check. added "Desktop Experience" role feature Tried HTTPS with Basic Authentication on port 443. Does not work. No other services are running like Sharepoint. Check. confirmed user has read/write NT level permissions for the folder/virtual dir tried net use * http://localhost /user:MYDOMAIN\me myPass get error 1920, if I don't authenticate I get error 67 confirmed I'm not applying filtering to WebDAV: <requestFiltering> <fileExtensions applyToWebDAV="false" /> <verbs applyToWebDAV="false" /> <hiddenSegments applyToWebDAV="false" /> 405 - HTTP verb used to access this page is not allowed. The page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access. SHOULD I JUST GIVE UP? Other questions that helped none: 405 - ‘Method not Allowed’ adding service hosted in IIS7 webdav on iis7.5 - simply cannot make it work http://studentguru.gr/b/kingherc/archive/2009/11/21/webdav-for-iis-7-on-windows-server-2008-r2.aspx

• Lighttpd - byte range request doesn't work. can't stream mp4

  - by w-01

  Am attempting to use the lastest flowplayer. (if it could work it would be pretty awesome btw) http://flowplayer.org One of the cool things about it is it uses the new HTML5 video element and supports random seeking/playback. In order to do this, you need a byte range request capable server on the backend. Luckily I'm using Lighttpd 1.5.0 on the backend. Unfortunately the current behavior is that when I do a random seek, the video simply restarts itself from the beginning. the docs say: "For HTML5 video you don't have to do any client side configuration. If your server supports byte range requests then seeking should work on the fly. Most servers including Apache, Nginx and Lighttpd support this." On my page, using chrome web developer tools, i can see when the video is requested, the server response headers indicate it is able to acce[t byte ranges. Accept-Ranges:bytes when I do random seek in the player, I can see that that byte ranges are request appropriately in the request header: Range: bytes=5668-10785 I can also verify the moov atom is at the front of the video file. My question here is if there is something else on the lighttpd side i'm missing in order to enable byte-range requests? The reason i ask is because the current behavior suggests that the lighttpd simply doesn't understand the byte range request and is just reserving the video from the beginning. Update it's clearer to put this here. As per RJS' suggestion I ran a curl command. in the response it looks like lighttpd is working as expected. Content-Range: bytes 1602355-18844965/18844966 Content-Length: 17242611

• maillog "No route to host" error

  I have a CentOS server. It has sendmail installed but not used for a mail server. I forwarded the root email to another email address.

Is there any configuration that I can change to prevent this error? I want all emails to the root to be forwarded to the forward address.

• Formatting an HP ProLiant dl380 G4

  - by i.h4d35

  I have an old HP ProLiant dl380 G4 server whose hard disk needs to be formatted. Unfortunately, I cannot seem to do so. For one, it doesn't seem to be detecting any Hard Drives attached to the Server. The Hard Disks show up in the Ctrl+A option (SCSI Configuration Utility). Also, while inserting the SmartStart CD (7.01 or 7.04), it shows a message that no logical drives are found and there aren't any options to create one. Alternately I've tried slipstreaming the SCSI Driver into the OS but that doesn't seem to be helping. Also, I have a USB Floppy drive (for the SCSI driver) but that doesn't seem to be detected. Also, directly installing the OS (MS Server 2003 Standard Edition) obviously doesn't work (shows no hard disk found) Could anyone please advise as to what other needs to be done to format my server? Also please tell me what are the possible errors/mistakes which've been made so that I can learn from them. I went through some questions here on ServerFault and the HP guides here but they weren't of much help to a n00b like me. Thanks in Advance.
