• Melting Laptop Power Supply Tip

  - by AlReece45

  Several (6-7) months ago, my laptop power supply cord got a cut in it and stopped working. Having gotten cheap (and short) power supplies in the past, I decided to buy 2 brand new ones from the manufacturer (ASUS). Now, I used my laptop a little less than usual between February and March. During that time I noticed a few times that the power supply, even though plugged in, did not provide power. Often the computer would just off on me. I figured it was just that one power supply being bad. I had left the alternate at my parent's house in another state and asked them to ship it to me. Now, at work the other day I wanted to get a file off the of hard disk. So I booted it up, knowing that it had a low battery, plugged it in. During the first 2 minutes of use, I was told that the battery was low and I should plug it in. I unplugged it, inspected the end (Being plugged in, this was suspicious), and decided I shouldn't plug it back in-- the plastic on the tip was melting from the heat of the metal on the tip. The computer had simply booted up and I had the file-manager open. It had not been on for more than 10 hours. Now I know that computers tend to get pretty hot. However, the melting point of plastic is usually above 200C.. so that's much hotter than the computer should be generating. I went and bought a THIRD power supply. This time a universal one from Best Buy (it was very fast to buy and test). I tried it out on the computer and it's tip is melting as well. My older laptop that uses the universal power supply uses it perfectly (has been about a week and a part of use now). I have tried using the computer without the battery, with the same effect. Obviously, this is not a problem with the power supply. My room mate and I being trained computer techs were contemplating taking the computer apart and desoldering and resoldering on the power tip. (The computer is about 6 months out of its 2-year warranty). We're hoping that will correct the issue as I would prefer to devote my money on a Good Desktop rather than yet ANOTHER $1200+ laptop. Is there any thing I'm missing here that might cause the the tip on the power unit to melt?

• understanding my site's DNS records

  - by DaveM

  firstly apologies for using the word 'pointage' this is the word my french domain registrar uses so I may have used to wrong term. OK I would like to better understand what is going on on my 'pointage' record on my domain registrars site. for my (currently empty) web site it reports the following details... Type : Host : Destination A : www.mydomain.org : 62.210.176.146 A : mail.mydomain.org : 84.246.225.176 Mx : .mydomain.org : mail.mydomain.org I think I understand the MX record, that simply relays anything onto the mail.mydomain.org location. However why are the destination for the www and mail domains different. Even more confusing (for me) is the fact that if I ping either of www.mydomain.org or mail.mydomain.org the ping returns a different IP address. This IP address is consistent with that of my server (ie 92.39.247.92). So what exactly is going on ? I'm sure I could find the information on the web,I've read a few thing on the debianhelp site regarding DNS records, and it seems to suggest that the record should be a reverse lookup, but certains isn't the reverse of my servers IP ? but I don't what I should be looking for, so links to docs and search terms for google will be happily accepteed (even though they go against the grain of SO answers to question). thanks in advance. David. ps. I should add that everything seems to work just fine, and I've just descovered this part of the management page of my registrar. Edit: Addition of DNS records and ping results. The DNS record for the site. From what I've read there should only realy be a single 'A' record, so has something gone wrong ? should I change it (remove the extras and then just point www.facilitee.org - .facilitee.org and mail.facilitee.org - .facilitee.org here is the DNS record A www.facilitee.org ? 92.39.247.92 A .facilitee.org ? 92.39.247.92 A mail.facilitee.org ? 92.39.247.92 A webmail.facilitee.org ? 92.39.247.92 MX .facilitee.org ? mail.facilitee.org ping results... ~$ ping www.facilitee.org PING www.facilitee.org (92.39.247.92) 56(84) bytes of data. 64 bytes from vps4576-cloud.dns26.com (92.39.247.92): ~$ ping mail.facilitee.org PING mail.facilitee.org (92.39.247.92) 56(84) bytes of data. 64 bytes from vps4576-cloud.dns26.com (92.39.247.92): So the DNS and the ping correspond, but the 'pointage' doesn't. ~ how can I get a report of the pointage records other than from my registrar ?

• How do you backup 40+ Centos5.5 servers?

  - by John Little

  We are embarrassed to ask this question. Apologies for our lack of UNIX expertise. We have inherited 40+ centos 5.5 servers, and don't know how to back them up. We need low level clone type images so that we could restore the servers from scratch if we had to replace the HDs etc. We have used the "dd" command, but we assume this only works if you want to back up one local disk to another, not 40 servers to one server with an external USB HD attached. All 40 servers have a pair of mirrored disks (dont know if its HW or SW raid). Most only have 100MB used. SErvers are running apache, zend, tomcat, mysql etc. Ideally we dont want to have to shut them down to backup (but could). We assume that standard unix commands like tar, cpio, rsync, scp etc. are of no use as they only copy files, not partitions, all attributes, groups etc. i.e. do not produce a result which can simply be re-imaged to a new HD to get the serer back from dead. We have a large SAN, a spare windows box and spare unix boxes, but these are only visible to one layer in the network. We have an unused Dell DL2000 monster tape unit, but no sw or documentation for it. WE have a copy of symantec backup exec, but we have no budget for unix client licenses. (The company has negative amounts of money). We need to be able to initiate the backup remotely, as we can only access the servers in person in an emergency (i.e. to restore) Googling returns some applications to do this, e.g. clonezilla - looks difficult to install and invasive. Mondo, only seems to support backup if you are local to the machine. Amanda might be an option, but looks like days/weeks of work to learn and setup? Is there anything built into Centos, or do we have to go the route of installing, learning and configuring a set of backup softwares? Any ideas? This must be a pretty standard problem which goggling doesnt give an obvious answer.

• RDP exits immediately after connecting to Windows Server 2008 R2

  - by carpat

  Background: I recently got a Windows cloud VPS server. I don't have much experience with server admin (I'm a programmer), and what little I do have is with linux servers. Ever since getting the server I've been having issues with RDP. I can connect about two or three times, after which point I can't connect until one of the tech guys "fixes" it (see below). When I connect, I can stay connected for hours with no problem. When the problem connecting starts, the first time I try to log in, the remote desktop window pops up, starts connecting, and then exits with "Your Remote Desktop session has ended". After that, for about 10-20 minutes if I try to connect again, the connections times out with Remote Desktop can't connect to the computer for one of these reasons: 1) Remote access on the server is not enabled 2) The remote computer is turned off 3) The remote computer is not available on the network then goes back to connecting once and immediately disconnecting. All of the updates are installed. The firewall has been correctly configured to let RDP traffic through. The remote setting is "Allow connections from computers running any version of Remote Desktop". I tried creating a second user, and when I can't connect, I can't connect to that user either. I've tried both soft and hard reboots, neither of which help. I've tried connecting from two different computers (both running Windows 7) from two different networks (work and home), and the behavior is the same. Everything else on the server continues to run fine (IIS-served http pages, Tomcat-served java pages, svn, ping). The "fix" that the tech guys supply is simply logging into the console on their end, after which point I can connnect 2 or 3 times again. The event viewer on the server has "authentication failure" (or something similar) events generated when I attempt to log in and can't. I can't get to the actual event at the moment as I'm currently in the can't connect stage, and waiting for the techs to log in. But when I searched for the event earlier this morning I couldn't find anything useful. Can anyone help?

• SQL Transactional Replication snapshot not applying

  - by dmch2

  Hi, I'm using SQL Transactional Replication with pull subscriptions to replicate databases (hosting their own distribution database) from several servers across a VPN to a central server. I've got the first 2 databases working fine but the 3rd one is causing me problems. My subscription server is SQL 2008, the source systems are all SQL 2005. The source databases are a few 100Mb in size and contain audit data so are simply growing slowly by adding new records at approx 1kb a second. As far as the replication monitor, Agent logs and event logs show everything is working fine - except that no data appears in my subscription database. The distribution agent doesn't seem to want to read the snapshot (and hence the initial state and schema) from the publisher. New transactions aren't applied although they do seem to be arriving OK as the replication monitor shows things like '5 transactions with 10 commands were delivered'. I would expect (as in previous times) to see statements about data being BCPed in the replication monitor. The snapshot is on the publisher on a shared folder. The subscriber can view the snapshot OK (\\repldata) and the alt snapshot folder is pointing at it. But the distribution agent doesn't seem to be making an attempt to do read it. I tried changing the snapshot path to something that's incorrect and didn't even get an error saying that it couldn't access it. After lots of googling etc I found that sp_MSget_repl_commands is called by the subscriber on the distribution database on the publisher. Running a profiler I can see that it's only called for one agent Id. After a reinit it's called for sequence number 0x0 as expected so I thought that would mean it's would look for the snapshot. However, looking on the publisher I see that there's data for two agents - the snapshot agent and the log reader agent (which is being queries). So I guess I need to tell the distribution agent to get the data for both. But how? and more importantly - why? It worked fine on the other two servers I've replicated. I'm not an SQL novice but this is pretty much my first go at replication so don't be afraid to accuse me of missing something obvious/stupid! I can get log files (eg from the distribution agent) if you want but they don't seem to have any errors in them - it just starts up and starts applying log reader agent changes. Cheers Dave

• Sharing files between multiple sites using only desktop software

  - by perlyking

  Our organisation has three sites; a head office, where the master copies of company files are stored, plus two branch offices using only workstations and a NAS or two. Currently we're talking about <10GB. At the main office, we have no admin access to the file server, as this is entirely controlled by the larger institution where we are located. For the same reason, we have no VPN remote access to this network. Instead, we simply have access to a network share using over a Novell LAN. Question: how can we share files between offices in way that minimises latency, i.e. that gives us a mirror of the main network share at each site? (There is little likelihood of concurrent editing, and we can live with the odd file conflict now and again). Up to now branch office staff have had to use GotoMyPC-type solutions to remotely access files held at the main office. Or email. I was hoping to use Google Drive on a dedicated workstation at each office to sync the contents of the network share (head office) or NAS (branch offices) via the cloud, but at my last attempt (29 Jun '12), the Google Drive installer would not allow me to designate the remote network share as the "target" folder. (I chose Google Drive over Drobbox et al. as we already use GMail for corporate mail) The next idea was to use a designated workstation at head office to mirror the network share to a local drive, then use Google Drive to push that to the cloud. This seems a step too far. Nor do I have any good ideas about how to achieve this network/local mirroring, as we can't, for example, install the rsync daemon on the server. I do not want to use Google Drive locally on each workstation as this will inconvenience users, and more importantly, move files off the backed-up, well-maintained (UPS, RAID etc) network share at head office. Our budget is only in the £100's. Should we perhaps just ditch the head office server and use something like JungleDisk? At least this presents the user with what appears to be a mapped drive.

• PHP `virtual()` with Apache MultiViews not working after upgrade to Ubuntu 12.04

  - by Izzy

  I use PHP's virtual() directive quite a lot on one of my sites, including central elements. This worked fine for the last ~10 years -- but after upgrading (or rather moving, as it is on a new machine) to Ubuntu 12.04 it somehow got broken. Example setup (simplified) To make it easier to understand, I simplify some things (contents). So say I need a HTML fragment like <P>For further instructions, please look <A HREF='foobar'>here</P> in multiple pages. 10 years ago, I used SSI for that, so it is put into a file in a central place -- so if e.g. the targeted URL changes, I only need to update it in one place. To serve multiple languages, I have Apache's MultiViews enabled -- and at $DOCUMENT_ROOT/central/ there are the files: foobar.html (English variant, and the default) foobar.html.de (German variant). Now in the PHP code, I simply placed: <? virtual("/central/foobar"); ?> and let Apache take care to deliver the correct language variant. The problem As said, this worked fine for about 10 years: German visitors got the German variant, all others the English (depending on their preferred language). But after upgrading to Ubuntu 12.04, it no longer worked: Either nothing was delivered from the virtual() command, or (in connection with framesets) it even ended up in binary gibberish. Trying to figure out what happens, I played with a lot of things. I first thought MultiViews was (somehow) not available anymore -- but calling http://<server>/central/foobar showed the right variant, depending on the configured language preferences. This also proved there was nothing wrong with file permissions. The error.log gave no clues either (no error message thrown). Finally, just as a "last ressort", I changed the PHP command to <? virtual("central/foobar.html"); ?> -- and that very same file was in fact included. So PHP's virtual() function basically worked -- but the language dependend stuff obviously did no longer work together with it as it did before. Of course I tried to find some change (most likely in PHP's virtual() command), using Google a lot, and also searching the questions here -- unfortunately to no avail. Finally: The question Putting "design questions" aside (surely today I would design things differently -- but at least currently I miss the time to change that for a quite huge amount of pages): What can be done to make it work again? I surely missed something -- but I cannot figure out what...

• VPN Connection Causes Internal LAN Connection Loss with Server

  - by sleepisfortheweak

  I've tried configuring basic PPTP VPN at my small business using a number of different tutorials. As far as I can tell, the actual VPN connection worked fine, but upon connecting a client, the Server 'disappears' from the internal LAN. The RRAS service must be stopped before the connection is restored. My Setup: The network is simply a DSL Gateway/Router to the outside functioning as NAT/Firewall/DHCP. The server is a Win Server 2008 machine at fixed IP 192.168.1.200. The server has 1 NIC, so I used the 'custom' option when configuring RRAS. The RRAS settings should be default except that I've disabled ports for connection types I'm not using and reduced PPTP ports to 10. I've also created an address pool and disabled DHCP packet forwarding. The server only functions as a File Share and now a VPN Server. Local LAN computers all have mapped network shares to the server authenticated based on Local User/Group setup on the server. The Problem: The moment a client connects through VPN, the server 'disappears' from the local network. All mapped drives disconnect and there is no response to a ping 192.168.1.200. Even if the client disconnects, the server does not re-appear at that address until the RRAS service is stopped. I've Tried: Using an Address Pool inside and outside the local subnet. Using DCHP Relay Checking Inbound/Outbound filters (none enabled) The fact that nothing I've tried has had any effect, and that I can connect and successfully obtain an IP tells me that it's something more fundamental I'm missing. My gut tells me that it's something to do with the second IP address added by the VPN client somehow taking over the interface or traffic from the local LAN accidently getting routed to the VPN client instead of handled at the server once RRAS has become 'active' when a client connects. Hopefully this may be obvious to someone with real IT experience. I've been doing this a while and almost never been stumped. I'm starting to think it might actually be something tricky since my setup is pretty basic yet refuses to work. I'll be happy to include more info if this doesn't ring any bells right away for anyone. Thanks

• Should I choose KVM/XEN over OpenVZ or use them together?

  - by Krystian

  I've got a dual xeon e5504 server, with [for now] only 8GB of ram. Storage is'n impressive either: 3x 146GB sas in raid5 + 500GB sata drives. Currently it works as a development server, but it's over speced for our needs and since our development methods changed through last 2 years we decided it will work as a production system for some of our applications + we would like to have a separate system for testing/research. Our apps are mainly web apps deployed on tomcats [plural as some of the apps require older versions] and connected to Postgres. I would like to have a production system, where only httpd+tomcat+db are setup and nothing else runs there. Sterile system. Apart from that, I would like a test system, where I can play with different JVM settings, deploy my test apps, play with tomcat/httpd settings and restart them without interfering with the production system. Apart from that, I would like to be able to play with different linux flavors, with newer kernels to test how they work etc. I know, this is not possible with OpenVZ and I would have to choose KVM for that. I am thinking about merging the two, and setting up a KVM to be able to work with different systems [linux only to be frank] + use openVZ to setup separate machines for my development needs. I would simply go with that, but reading here and there about the performance impact full virtualization has over containers and looking at the specs of my server makes me think twice about it. I don't want to loose too much performance, especially because of the nature of my apps [few JVMs running at the same time]. It will be my first time with virtualization, apart from using desktop virtualbox/vmserver. Although I am a fast learner I don't want to mess with the main system so much that it will break the production apps or make them crawl. Although they are more or less internal apps and they don't produce much load, they need to be stable. I've read, that KVM host is a normal linux installation and it allows to run normal processes on it. If that is so, does it allow to run openVZ as well? I mean... can I have KVM and OpenVZ running on the same system/kernel? Or do I have to setup another system to run OpenVZ containers? How much performance impact can this have for me? Will my hardware suffice? oh and one more thing... unfortunately I'm quite limited with the funds... I'm looking for a free solution only :/

• How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment

  - by user69508

  (Please forgive if this is posted in an incorrect forum. We didn’t know exactly where to post it.) We have an ASP.NET Web API single page application - a browser-based app running in IIS to serve up HTML5/CSS3/JavaScript, which talks to the ASP.NET Web API endpoint only to access a database and transfer JSON data. Everything is working great in our development environment - that is, we have one Visual Studio solution with an ASP.NET Web API project and two class library projects for data access. While development and testing on development boxes, using IIS Express to a localhost:port to run the site and access the Web API, everything is fine. Now we need to move it to a production environment (and we’re having problems - or just not understanding what needs to be done). The production environment is all internal (nothing will be exposed on the public Internet). There are two domains. One domain, the corporate domain, is where all users login normally. The other domain, the process domain, contains the SQL Server instance that our app and Web API will need to access. The IT staff wants to put a DMZ between the two domains to house the IIS app and shield the users on the corporate domain from having access into the process domain directly. So, I guess what they want is: corp domain (end users) <– firewall (open port 80) <– DMZ (web server running IIS) <– firewall (open port 80 or 1433????) <– process domain (IIS for Web API and SQL Server) We’re developers and don’t really understand all the networking aspects, so we’re wondering how to deploy our browser/Web API application in this scenario. Do we need to break up our application so that all the client code (HTML5/CSS3/JavaScript/images/etc.) is on the IIS server in the DMZ, while the Web API gets installed on the server in the process domain? Or, does the entire app (client code and Web API) stay together on the IIS server in the DMZ, which then somehow accesses the SQL Server instance to get data? From the IIS server and app in the DMZ, would you simply access the Web API on the server in the process domain by going to "http://server/appname/api/getitmes"? In the second firewall between the DMZ and the process domain, would you have to open port 1433 or just port 80 since the Web API is a HTTP endpoint? Or, is there some better way of deployment (i.e., how ASP.NET Web API single page applications written all in HTML5 and JavaScript supposed to be deployed to production environments?)? I’m sure there are other questions, but we’ll start with these. Thanks!!! (Note: the servers are Win2k8 R2, SQL Server 2k8 R2, and IIS 7.5.)

• Troubleshooting Network Speeds -- The Age Old Inquiry

  - by John K

  I'm looking for help with what I'm sure is an age old question. I've found myself in a situation of yearning to understand network throughput more clearly, but I can't seem to find information that makes it "click" We have a few servers distributed geographically, running various versions of Windows. Assuming we always use one host (a desktop) as the source, when copying data from that host to other servers across the country, we see a high variance in speed. In some cases, we can copy data at 12MB/s consistently, in others, we're seeing 0.8 MB/s. It should be noted, after testing 8 destinations, we always seem to be at either 0.6-0.8MB/s or 11-12 MB/s. In the building we're primarily concerned with, we have an OC-3 connection to our ISP. I know there are a lot of variables at play, but I guess I was hoping the experts here could help answer a few basic questions to help bolster my understanding. 1.) For older machines, running Windows XP, server 2003, etc, with a 100Mbps Ethernet card and 72 ms typical latency, does 0.8 MB/s sound at all reasonable? Or do you think that slow enough to indicate a problem? 2.) The classic "mathematical fastest speed" of "throughput = TCP window / latency," is, in our case, calculated to 0.8 MB/s (64Kb / 72 ms). My understanding is that is an upper bounds; that you would never expect to reach (due to overhead) let alone surpass that speed. In some cases though, we're seeing speeds of 12.3 MB/s. There are Steelhead accelerators scattered around the network, could those account for such a higher transfer rate? 3.) It's been suggested that the use SMB vs. SMB2 could explain the differences in speed. Indeed, as expected, packet captures show both being used depending on the OS versions in play, as we would expect. I understand what determines SMB2 being used or not, but I'm curious to know what kind of performance gain you can expect with SMB2. My problem simply seems to be a lack of experience, and more importantly, perspective, in terms of what are and are not reasonable network speeds. Could anyone help impart come context/perspective?

• Creating a fallback error page for nginx when root directory does not exist

  I have set up an any-domain config on my nginx server - to reduce the amount of work needed when I open a new site/domain. This config allows me to simply create a folder in /usr/share/nginx/sites/ with the name of the domain/subdomain and then it just works.™ server { # Catch all domains starting with only "www." and boot them to non "www." domain. listen 80; server_name ~^www\.(.*)$; return 301 $scheme://$1$request_uri; } server { # Catch all domains that do not start with "www." listen 80; server_name ~^(?!www\.).+; client_max_body_size 20M; # Send all requests to the appropriate host root /usr/share/nginx/sites/$host; index index.html index.htm index.php; location / { try_files $uri $uri/ =404; } recursive_error_pages on; error_page 400 /errorpages/error.php?e=400&u=$uri&h=$host&s=$scheme; error_page 401 /errorpages/error.php?e=401&u=$uri&h=$host&s=$scheme; error_page 403 /errorpages/error.php?e=403&u=$uri&h=$host&s=$scheme; error_page 404 /errorpages/error.php?e=404&u=$uri&h=$host&s=$scheme; error_page 418 /errorpages/error.php?e=418&u=$uri&h=$host&s=$scheme; error_page 500 /errorpages/error.php?e=500&u=$uri&h=$host&s=$scheme; error_page 501 /errorpages/error.php?e=501&u=$uri&h=$host&s=$scheme; error_page 503 /errorpages/error.php?e=503&u=$uri&h=$host&s=$scheme; error_page 504 /errorpages/error.php?e=504&u=$uri&h=$host&s=$scheme; location ~ \.(php|html) { include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_intercept_errors on; } } However there is one issue that I'd like to resolve, and that is when a domain that doesn't have a folder in the sites directory, nginx throws an internal 500 error page because it cannot redirect to /errorpages/error.php as it doesn't exist. How can I create a fallback error page that will catch these failed requests?

• nginx rewrite for wikkawiki

  - by Hans

  Just setup WikkaWiki on my server, I have been trying to have the links go from wiki.mysite.info/wikka.php?wakka=Start into wiki.mysite.info/DotMG. I tried following their guide at http://docs.wikkawiki.org/ModRewrite, however it seems incomplete and outdated. Furthermore, as of version 1.3.2 base_url isn't even manually configurable from the wikka.config.php file. I am using version 1.3.2 of WikkaWiki. My nginx virtual hosts file contains: server { listen 80; server_name wiki.mysite.info; root /usr/share/nginx/wikka/; access_log /usr/share/nginx/.access/wikka; error_log /usr/share/nginx/.error/wikka error; location / { index index.php; try_files $uri $uri/ @wikka; } location @wikka { rewrite ^(.*/[^\./]*[^/])$ $1/ last; rewrite ^(.*)$ /wikka.php?wakka=$1 last; } location ~* \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include /etc/nginx/fastcgi_params; } } Thus far it works, I can go to wiki.mysite.info/APage and it'll display that page, however it doesn't work on all pages, sometime the browser simply downloads the page (For some reason it always downloads the Start page). Also when I go to wiki.mysite.info/ it downloads the wikka.php file... Furthermore, the links on the wiki have the wikka.php?wakka= so whenever I navigate around the wiki, it goes back to being wiki.mysite.info/wikka.php?wakka=APage. I think something is wrong with my rewrite but I can't say for sure. Contents of the fastcgi_params: fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_FILENAME $request_filename; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param HTTPS $server_https; # PHP only, required if PHP was built with --enable-force-cgi-redirect fastcgi_param REDIRECT_STATUS 200;

• Linux software RAID6: 3 drives offline - how to force online?

  - by Ole Tange

  This is similar to 3 drives fell out of Raid6 mdadm - rebuilding? except that it is not due to a failing cable. Instead the 3rd drive fell offline during rebuild of another drive. The drive failed with: kernel: end_request: I/O error, dev sdc, sector 293732432 kernel: md/raid:md0: read error not correctable (sector 293734224 on sdc). After rebooting both these sectors and the sectors around them are fine. This leads me to believe the error is intermittent and thus the device simply took too long to error correct the sector and remap it. I expect that no data was written to the RAID after it failed. Therefore I hope that if I can kick the last failing device online that the RAID is fine and that the xfs_filesystem is OK, maybe with a few missing recent files. Taking a backup of the disks in the RAID takes 24 hours, so I would prefer that the solution works the first time. I have therefore set up a test scenario: export PRE=3 parallel dd if=/dev/zero of=/tmp/raid${PRE}{} bs=1k count=1000k ::: 1 2 3 4 5 parallel mknod /dev/loop${PRE}{} b 7 ${PRE}{} \; losetup /dev/loop${PRE}{} /tmp/raid${PRE}{} ::: 1 2 3 4 5 mdadm --create /dev/md$PRE -c 4096 --level=6 --raid-devices=5 /dev/loop${PRE}[12345] cat /proc/mdstat mkfs.xfs -f /dev/md$PRE mkdir -p /mnt/disk2 umount -l /mnt/disk2 mount /dev/md$PRE /mnt/disk2 seq 1000 | parallel -j1 mkdir -p /mnt/disk2/{}\;cp /bin/* /mnt/disk2/{}\;sleep 0.5 & mdadm --fail /dev/md$PRE /dev/loop${PRE}3 /dev/loop${PRE}4 cat /proc/mdstat # Assume reboot so no process is using the dir kill %1; sync & kill %1; sync & # Force fail one too many mdadm --fail /dev/md$PRE /dev/loop${PRE}1 parallel --tag -k mdadm -E ::: /dev/loop${PRE}? | grep Upda # loop 2,5 are newest. loop1 almost newest => force add loop1 Next step is to add loop1 back - and this is where I am stuck. After that do a xfs-consistency check. When that works, check that the solution also works on real devices (such a 4 USB sticks).

• netbook intel GMA 3150 external monitor 1920x1080 flicker problem

  - by seyenne

  Dear all, i recently purchased a acer netbook (apsire one d260). It runs flawlessly. Yesterday I bought a samsung 23" TFT with a native resolution of 1920x1080. According to the information found in the internet and my local computer dealer, the intel chipset can handle the native resolution of the monitor. However, this is only partly the case. I use the VGA cabel to connect, the monitor instantly switches to the native resolution and now the problem: Occasionaly, especially the first 2 hours after booting up, I have a flickering all over the screen, sometimes the entire screen is shaking and spinning around like crazy. I figured out, that lowering the resolution avoids the flicker but this helps only for some time. I can rule out that it's the monitor's problem since I found no issues with another notebook. Right now, I have no problems with the netbook, for about 30 minutes I didn't experience any issues... But I don't know for how long, it occurs without warning :-) I'm worried that if I would bring the netbook back to the dealer and explain my problem, after testing it on an external screen in the local shop, everything works just fine... And I won't get helped with the problem because I can't prove it. (I'm currently in Thailand and over here, customer service is nothing like back home in Germany) What can I do? Is this a driver related issue? (I installed the latest GPU driver) Is it because of the VGA cable? (But why does it work sometimes without any problems and with no issues on the other notebook) I monitored the GPU/CPU temperature, nothing changes really over time..Can it simply be a faulty GPU and is a replacement justifiable? I'm really stressed now because for the time I'm writing, the flickering didn't occur...but for sure, soon or later it will happen again.. I Forgot to mention, the problem also happens if the netbook runs on battery, unplugged. So the only hardware that is plugged is the TFT screen. ...........and here it comes again, flickering has just begun. NEED HELP! Thank you all for reading through this and giving any suggestions if possible. Cheers

• How to reliably map vSphere disks <-> Linux devices

  - by brianmcgee

  Task at hand After a virtual disk has been added to a Linux VM on vSphere 5, we need to identify the disks in order to automate the LVM storage provision. The virtual disks may reside on different datastores (e.g. sas or flash) and although they may be of the same size, their speed may vary. So I need a method to map the vSphere disks to Linux devices. Ideas Through the vSphere API, I am able to get the device info: Data Object Type: VirtualDiskFlatVer2BackingInfo Parent Managed Object ID: vm-230 Property Path: config.hardware.device[2000].backing Properties Name Type Value ChangeId string Unset contentId string "d58ec8c12486ea55c6f6d913642e1801" datastore ManagedObjectReference:Datastore datastore-216 (W5-CFAS012-Hybrid-CL20-004) deltaDiskFormat string "redoLogFormat" deltaGrainSize int Unset digestEnabled boolean false diskMode string "persistent" dynamicProperty DynamicProperty[] Unset dynamicType string Unset eagerlyScrub boolean Unset fileName string "[W5-CFAS012-Hybrid-CL20-004] l****9-000001.vmdk" parent VirtualDiskFlatVer2BackingInfo parent split boolean false thinProvisioned boolean false uuid string "6000C295-ab45-704e-9497-b25d2ba8dc00" writeThrough boolean false And on Linux I may read the uuid strings: [root@lx***** ~]# lsscsi -t [1:0:0:0] cd/dvd ata: /dev/sr0 [2:0:0:0] disk sas:0x5000c295ab45704e /dev/sda [3:0:0:0] disk sas:0x5000c2932dfa693f /dev/sdb [3:0:1:0] disk sas:0x5000c29dcd64314a /dev/sdc As you can see, the uuid string of disk /dev/sda looks somehow familiar to the string that is visible in the VMware API. Only the first hex digit is different (5 vs. 6) and it is only present to the third hyphen. So this looks promising... Alternative idea Select disks by controller. But is it reliable that the ascending SCSI Id also matches the next vSphere virtual disk? What happens if I add another DVD-ROM drive / USB Thumb drive? This will probably introduce new SCSI devices in between. Thats the cause why I think I will discard this idea. Questions Does someone know an easier method to map vSphere disks and Linux devices? Can someone explain the differences in the uuid strings? (I think this has something to do with SAS adressing initiator and target... WWN like...) May I reliably map devices by using those uuid strings? How about SCSI virtual disks? There is no uuid visible then... This task seems to be so obvious. Why doesn't Vmware think about this and simply add a way to query the disk mapping via Vmware Tools?

• Galaxy Tab 3 producing continuous LightSensor error in LogCat

  - by Richard Tingle

  I am using a Galaxy Tab 3 as a test device for writing an android app. As such I'm interested in the output of the LogCat which is being filled with these error level messages. The device itself appears to work correctly, apps which rely on the light sensor correctly respond to it and the number in the error itself goes down if the light sensor is obscured. If I wasn't using it to develop apps I wouldn't even be aware of the issue but I believe it is an issue with the device itself not my app: simply plugging the tab 3 into the computer and using Eclipse - ADT to look at the LogCat without any app running leads to these errors being shown. I know I could filter the LogCat to ignore these errors but inconvenience aside; they concern me. A sample of the log cat is below (it generates errors continuously). This is on verbose so it includes some debug level (D/) messages as well as the error level messages (E/). How can I correct the device to no longer generate these errors. 06-11 10:08:45.789: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:45.992: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.195: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.398: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.601: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.804: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.007: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.210: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.414: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.617: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.820: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:48.023: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:48.039: D/dalvikvm(15201): GC_CONCURRENT freed 1947K, 17% free 16973K/20359K, paused 13ms+13ms, total 50ms 06-11 10:08:48.226: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:48.429: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13 06-11 10:08:48.632: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13 06-11 10:08:48.632: D/STATUSBAR-NetworkController(472): refreshSignalCluster: data=0 bt=false 06-11 10:08:48.835: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.039: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.242: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.445: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13 06-11 10:08:49.632: D/STATUSBAR-NetworkController(472): refreshSignalCluster: data=0 bt=false 06-11 10:08:49.648: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.851: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13

• Ubuntu + SSL ports + AVAST

  - by jurajvt

  I have an interesting problem with communication via standard SSL ports. Fresh installed Ubuntu 14.04 server + Postfix + Dovecot, SASL authentication provided by Dovecot, self-signed certificate generated trough the Dovecot script mkcert.sh. Redirected ports on ZyWALL USG 200. I can send and receive e-mails from outside with standard ports 25 and 110, but not over 587. I am connecting to my server from machine with Windows 8.1 + VMWare Player + Ubuntu 14.04 Desktop + ssh. On Windows host I have installed Avast! antivirus. When I am trying to telnet from virtual machine to server over 587, it refused connection. But when I turn on Avast! it let me in to message Connected to... Same with nmap. When Avast! is turned on it is show me all SSL ports. When I turned it off, only standard ports appeared. OpenSSL shows me CONNECTED(00000003). But outside virtual machine directly in Windows 8.1 using nmap with zenmap there are not opened SSL ports in both Avast! states. From other external linux machines are problems with touching SSL ports same - refused. I have turned on submission in master.cf and 587 port is correctly listening on 0.0.0.0 in process master.pid which belongs to Postfix. I can telnet, or nmap over port 587 to my domain directly from server. Other ports like 995, 993 are OK on localhost, too. It is true, that I can't send emails via 587 anyway (Avast! turned on/off), but I can see ports opened. It is possible, that I have simply bad certificate and Avast! has right one, so with turned it on I can see opened ports? EDIT: To be more clear, I can't see or using port 587 everywhere from outside (tried Thunderbird, telnet, openssl, nmap, putty, swaks; both from Linux or Windows machines) and that is my problem. It was only by chance that I saw opened ports when Avast! is turned on.

• Wifi network stopped being visible (and usable) (Linksys wag320n)

  - by s427

  Basically, my wifi network simply stopped working for no apparent reason. It doesn't appear in the list of the available networks anymore. I can see all my neighbors' networks, but not mine. It's as if it doesn't exist anymore. The internet connection (non-wifi), which goes through the same modem/router, is fine though. I already had a similar problem about one year ago (see here: Wifi network SSID not visible ), just after buying this very modem. I finally got it to work after performing two factory resets and getting rid of the Cisco "Magic" software; but this time it's not working. I use a linksys router-modem (WAG320N) which is directly connected (via network cable) to my desktop computer (Windows 7). I have (mainly) two devices that use the wifi network: my phone (Samsung Galaxy Nexus) and an Asus tablet (TF201, aka Transformer Prime). I also resurrected an old laptop computer (Dell, running Windows XP) to test that, and it doesn't see anything either (apart from the 20 other wifi networks, of course ^^). This wifi network was working just fine and has been for about a year. I haven't touched the modem settings so I have no idea what's causing the problem. I tried: making my phone "forget" about my network, hoping it would see it again after that: no luck. re-entering the network informations (SSID/password) manually on my phone: still no luck (says it's not in range) exporting the modem configuration, resetting the modem (factory reset, via modem admin), restarting it, importing the configuration: nope. factory reset, turning it off for 15 minutes, restarting, re-factory reset, and entering the configuration manually: still nothing. Has anybody experienced something similar before? Have you any suggestion to fix that? Thanks in advance. PS: to clear things up, here are the settings of my modem regarding wifi: Basic wireless settings: Configuration: manual Radio Band: 2.4GHz Wireless Network Mode: B/G/N-Mixed SSID: s427 Channel Bandwidth: Wide - 40 MHz Channel Wide Channel: 9 - 2.452GHz Standard Channel: 11 - 2.462GHz SSID Broadcast: Enable Advanced Wireless Settings AP Isolation: Disable Authentication Type: Auto Basic Rate: Default Transmission Rate: Auto N Transmission Rate: Auto CTS Protection Mode: Disable Beacon Interval: 100 DTIM Interval: 1 Fragmentation Threshold: 2346 RTS Threshold: 2346

• Remote Debian System Preventing Logon

  - by choobablue

  I have a dozen or so single board computers on a network running Debian (squeeze) and access them via ssh (ssh server is dropbear). To give an idea of the hardware of these computers they're 1.2 GHz x86 processors, 1GB of RAM and 4GB flash drives formatted as ext2 (I avoided ext3 to prevent the added flash write stress from journaling), there is also a swap partition on the drive. Normally the setup I'm using works great and I can access all the computers. Every once in a while one will prevent access. What happens is I try to connect via ssh (putty) and it gives me the login prompt, I enter the username and password and it responds 'Access Denied' and it will also refuse any public key in ~/.ssh/authorized_keys. The credentials are correct as they worked previously. The computer responds to pings and putty recognizes the server public key, which implies to me the system is still running. Restarting the server fixes the problem and I can log in again. (I tried a temporary fix of putting shutdown -r now in the root crontab but this doesn't seem to reliably be run once the hang happens) Once I restart however there doesn't seem to be any information in any of the system logs to indicate what happened, the logs are simply empty for that time period, as if the system had crashed. There is some custom software running on the system which appears to stop working (which is why I wanted to ssh to begin with). I'm assuming that this program is the source of the problems but I'm unsure of how it would cause it and how to debug what is happening. The most likely explanation I can think of is that there is a memory leak in the other program that then prevents dropbear from spawning a new login shell (and crontab from executing shutdown) as there is not enough free memory. But looking at memory usage of the other (working) computers there doesn't seem to be any meaningful increase in memory to indicate a leak (unless it's a very big, fast acting and rare leak). I would think that when the OS ran out of memory it would restart the system or kill processes (the Linux kernel restarts right?). The other thing I wonder about is if the fact that they are running off a flash drive could have some effect, especially the swap partition (which I think I should remove to prevent wear of the flash), but the flash drives are young (~1 month) and I don't think that wear would be a factor yet. Does anybody have an idea of what could cause these symptoms, if it could be done by a memory leak, or something else I haven't thought of. And does anybody know of a method to try to debug the problem and find out more information about what's going wrong?

• 2 servers, high availability and faster response

  - by user17886

  I recently bought a second webserver because I worry about hardware failure of my old server. Now that I have that second server I wish to do a little more then just have one server standby and replicate all day. As long as it's there I might as well get some advantage our of it ! I have a website powered by ubuntu 12.04, nginx, php-fpm, apc, mysql (5.5) and couchdb. Im currently testing configurations where i can achieve failover AND make good use of the extra harware for faster responses / distributed load. The setup I am testing nowinvolves heartbeat for ip failover and two identical servers. Of the two servers only one has a public ip adress. If one server crashes the other server takes over the public ip adress. On an incoming request nginx forwards the request tot php-fpm to either server a of server b (50/50 if both servers are alive). Once the request has been send to php-fpm both servers look at localhost for the mysql server. I use master-master mysql replication for this. The file system is synced with lsyncd. This works pretty well but Im reading it's discouraged by the (mysql) community. Another option I could think of is to use one server as a mysql master and one server as a web/php server. The servers would still sync their filesystem, would still run the same duplicate software (nginx,mysql) but master slave mysql replication could be used. As long as bother servers are alive I could just prefer nginx to listen to ip a and mysql to ip b. If one server is down, the other server could take over the task of the other server, simply by ip switching. But im completely new at this so I would greatly value your expert advice. Is either of the two setups any good ? If you have any thoughts on this please let me know ! PS, virtualisation, hosting on different locations or active/passive setups are not solutions im looking for. I find virtual server either too slow or too expensive. I already have a passive failover on another location. But in case of a crash I found the site was still unreachable for too long due to dns caching.

• Glassfish JSF/EAR Apache 2.2 proxy_ajp_mod Referred Content Missing (images/links/etc)

  - by BillR

  Full disclosure: Since this seems to be more of a configuration issue, I deleted this from Stack (where it wasn't getting any response) and reposted here. The problem is how to change the requestContextPath served up by Glassfish behind mod_proxy_ajp. The site/app runs fine if connecting directly to Glassfish port 8080 which is ultimately not what I want to do. So I need help with configuration for my servers and jsf deployment. I can see the issue but don't know how to resolve it. It has to do with the requestContextPath. Simply put, Apache directs to http://mysite.com/welcome.xhtml which is correct and what I want, but the page is minus the images and styles. The issue is Glassfish itself is still pointing to http://mysite.com/myapp/*. So all links it serves in the app/site still refer via the requestContextPath. That is the /myapp/* part of http://mysite.com/myapp/welcome.xhtml. When I look in the page source, images which are referred to with relative links still point to the requestContextPath (that is, /myapp/). This is fixable but a real pain. However with page links I can't set the relative path. If I hover over the contact page link I see http://mysite.com/myapp/contact.xhtml, and if I click it, I get 404. You can see the /myapp/ context path in the page source as well. If I type in the URL http://mysite.com/contact.xhtml I get the page minus its referred links (requestContextPath). On Apache ProxyPass / ajp://littlewalterserver:8009/myapp-web/ ProxyPassReverse / ajp://littlewalterserver:8009/myapp_Project-web On Glassfish asadmin create-network-listener --listenerport 8009 --protocol http-listener-1 --jkenabled true jk-connector I have tried going in to Glassfish and setting the web app as the default web app. I have changed the / in glassfish-web.xml (and checked to make sure it was the same in the EAR file). How can I get Glassfish to not include the /myapp/ context in the URLs? This has to be easy if you know how, but I don't know how, can someone help out here? Thanks.

• Install XP Mode with VirtualBox Using the VMLite Plugin

  - by Mysticgeek

  Would you like to run XP Mode, but prefer Sun’s VirtualBox for virtualization?  Thanks to the free VMLite plugin, you can quickly and easily run XP Mode in or alongside VirtualBox. Yesterday we showed you one method to install XP Mode in VirtualBox, unfortunately in that situation you lose XP’s activation, and it isn’t possible to reactivate it. Today we show you a tried and true method for running XP mode in VirtualBox and integrating it seamlessly with Windows 7. Note: You need to have Windows 7 Professional or above to use XP Mode in this manner. Install XP Mode Make sure you’re logged in with Administrator rights for the entire process. The first thing you’ll want to do is install XP Mode on your system (link below). You don’t need to install Windows Virtual PC. Go through and install XP Mode using the defaults. Install VirtualBox Next you’ll need to install VirtualBox 3.1.2 or higher if it isn’t installed already. If you have an older version of VirtualBox installed, make sure to update it. During setup you’re notified that your network connection will be reset. Check the box next to Always trust software from “Sun Microsystems, Inc.” then click Install.   Setup only takes a couple of minutes, and does not require a reboot…which is always nice. Install VMLite XP Mode Plugin The next thing we’ll need to install is the VMLite XP Mode Plugin. Again Installation is simple following the install wizard. During the install like with VirtualBox you’ll be asked to install the device software. After it’s installed go to the Start menu and run VMLite Wizard as Administrator. Select the location of the XP Mode Package which by default should be in C:\Program Files\Windows XP Mode. Accept the EULA…and notice that it’s meant for Windows 7 Professional, Enterprise, and Ultimate editions. Next, name the machine, choose the install folder, and type in a password. Select if you want Automatic Updates turned on or not. Wait while the process completes then click Finish.   The VMLite XP Mode will set up to run the first time. That is all there is to this section. You can run XP Mode from within the VMLite Workstation right away.

• Install XP Mode with VirtualBox Using the VMLite Plugin

  - by Mysticgeek

  Would you like to run XP Mode, but prefer Sun’s VirtualBox for virtualization?  Thanks to the free VMLite plugin, you can quickly and easily run XP Mode in or alongside VirtualBox. Yesterday we showed you one method to install XP Mode in VirtualBox, unfortunately in that situation you lose XP’s activation, and it isn’t possible to reactivate it. Today we show you a tried and true method for running XP mode in VirtualBox and integrating it seamlessly with Windows 7. Note: You need to have Windows 7 Professional or above to use XP Mode in this manner. Install XP Mode Make sure you’re logged in with Administrator rights for the entire process. The first thing you’ll want to do is install XP Mode on your system (link below). You don’t need to install Windows Virtual PC. Go through and install XP Mode using the defaults. Install VirtualBox Next you’ll need to install VirtualBox 3.1.2 or higher if it isn’t installed already. If you have an older version of VirtualBox installed, make sure to update it. During setup you’re notified that your network connection will be reset. Check the box next to Always trust software from “Sun Microsystems, Inc.” then click Install.   Setup only takes a couple of minutes, and does not require a reboot…which is always nice. Install VMLite XP Mode Plugin The next thing we’ll need to install is the VMLite XP Mode Plugin. Again Installation is simple following the install wizard. During the install like with VirtualBox you’ll be asked to install the device software. After it’s installed go to the Start menu and run VMLite Wizard as Administrator. Select the location of the XP Mode Package which by default should be in C:\Program Files\Windows XP Mode. Accept the EULA…and notice that it’s meant for Windows 7 Professional, Enterprise, and Ultimate editions. Next, name the machine, choose the install folder, and type in a password. Select if you want Automatic Updates turned on or not. Wait while the process completes then click Finish.   The VMLite XP Mode will set up to run the first time. That is all there is to this section. You can run XP Mode from within the VMLite Workstation right away. XP Mode is fully activated already, and the Guest Additions are already installed, so there’s nothing else you need to do!  XP Mode is the whole way ready to use. Integration with VirtualBox Since we installed the VMLite Plugin, when you open VirtualBox you’ll see it listed as one of your machines and you can start it up from here.   Here we see VMLite XP Mode running in Sun VirtualBox.
