• Random shut down? Asus N53J Laptopi

  - by Mr.Y

  My Laptop is pretty new and today it random shut down on its own. I was surfing the net and the computer shut down on its own (Like losing power, without any warning). It was the 2nd time, the first time was 3 weeks ago. Btw it happens during cold days. I remember one time I was unable to turn on my laptop at all. So I'm pretty sure it's not related to heat issue... could it be the laptop is too "cold"? My room temperature is around 17=18 degree on average :P edit -I use Windows 7 Professional. -I run memtest86 once and it passed. -I run my laptop WITHOUT battery all the time.

• IRC Services with failover support?

  - by insertjokehere

  I run a single server (call it 'server A') IRC 'network', and thank to the generosity of some friends, I have been given a second server ('server B') that I can run an IRCd on in order to provide redundancy in case server A crashes. This is fine, I can set up a round-robin DNS with the servers linked. The problem I have is what to do about services? Does anyone know of a way to get the services to 'fail over' in case of a server failure? Eg, Server A starts off running the services, but suddenly crashes. Server B detects this and starts its own copy of the services (ideally with the same configuration and data as the services on Server B) One solution that comes it mind is to write a bot that each server runs, that sit in a channel periodically checking if the bot from the other server is in the channel. If it is, then all is well. If not, then failover. I would prefer not to have to code this myself though We are currently using Unreal IRCd and Anope services on Linux

• unable to properly execute binaries from PHP

  - by Lowgain

  I was building an app on a SUSE box, and had a binary called create_group for instance, which had a suid bit and allowed my PHP app to call exec('create group grpname'); and create a new group (there are others for users, etc). The binary was a small c script that calls setuid(0) and then runs the user creation stuff. This worked perfectly on the SUSE box I recently moved my project to Ubuntu and everything works fine except these binaries. I can run them from the shell and they work okay, but when I get the PHP app to run them it just does nothing. Is there anything Ubuntu would be doing differently that I'm missing?

• Debian, CentOS, Slackware, FreeBSD, OpenSolaris and Ubuntu Server Edition: Which one to use for an http web server?

  - by Ako

  I am going to install and administrate a virtual server for a small university. The server should run inside a virtual machine (VirtualBox OSE). It is only used in the university network and is invisible to the outside world. It should run Apache web server for PHP, MySQL and probably a mail server. I don't know which OS to use. Main criteria for choosing include ease of administration and updating, package management and performance. I wonder if anyone has any suggestions? And candidate OSs are: Debian, Ubuntu, CentOS, Slackware, FreeBSD, OpenSolaris. Add any other OS if you know any better alternatives.

• Looking for a small, portable, port-mirroring ethernet switch.

  - by user37244

  I recently had a mac go haywire, taking half a minute or more to get www.google.com loaded. Getting its owner to give up the machine for repair was like pulling teeth - they were insisting that it must be something to do with the network, since so much had changed with the local configuration at about the same time their box went haywire. I eventually set up a port mirror to a box that I could remote to so I could show that the mac was only irregularly getting packets onto the network. Demonstrating this faced an additional challenge: the latency of the remote desktop software I was using meant that I had to point to timestamps instead of just the moment the packet flashed up on the screen as my evidence. This particular user was the reason this was so challenging this time around, but I would like to have a box that I can cart from desk to desk to use wireshark on my laptop at any station where I need it. 3com, cisco, netgear, etc. (ad nauseum), all make switches that can be configured for port mirroring, but in my case, the smaller, the better. For the sake of my sanity, I'll probably end up running it off a battery anyway. If my laptop had two ethernet ports, this would be easy. So, whaddya recommand for a device that requires 0 configuration at each powerup (though I'm fine with poking at it for a while to set it up initially.) Small, light, and cheap enough to get it past purchasing? Thanks,

• Creating a Jenkins build farm in a hands-off manner?

  - by user183394

  My colleague and I have set up and run Jenkins on a KVM guest running Ubuntu 12.04 with good results for a while now. We are thinking about deploying a cluster of Jenkins CI hosts in master/slave configuration, with the libvirt slave plugin to keep our hardware count low. Our environment is strictly Linux (CentOS, Scientific Linux, Fedora, and Ubuntu). Both of us are competent in setting up large clusters. We typically use tools like cobbler + a configuration management tool (Puppet, Chef, and alike) to set up a large number of machines (physical and/or virtual) hands off (hundreds of nodes in less than an hour typical). We would like to do the same for nodes running Jenkins. But the step by step guide doesn't give us any clues in this regard. I did see a Multi-slave config plugin. But, being used to dealing with hundreds or more machines completely hands-off, clicking the UI for many machines just doesn't feel right. Can someone point to us a reference that talks about how to set up large cluster of Jenkins CI hosts more in the hands-off way?

• Allowing directory view/traversal for a specific VirtualHost in Apache 2.2

  - by warren

  I have the following vhost configured: <VirtualHost *:80> DocumentRoot /var/www/myvhost ServerName myv.host.com ServerAlias myv.host.com ErrorLog logs/myvhost-error_log CustomLog logs/myvhost-access_log combined ServerAdmin [email protected] <Directory /var/www/myvhost> AllowOverride All Options +Indexes </Directory> </VirtualHost> The configuration appears to be correct from the apachectl tool's perspective. However, I cannot get a directory listing on that vhost: Forbidden You don't have permission to access / on this server. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request. The error log shows the following: [Wed Mar 07 19:23:33 2012] [error] [client 66.6.145.214] Directory index forbidden by Options directive: /var/www/****** update2 More recently, the following is now kicking-into the error.log: [Wed Mar 07 20:16:10 2012] [error] [client 192.152.243.233] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /var/www/error/noindex.html update3 Today, the following is getting kicked-out: [Thu Mar 08 14:05:56 2012] [error] [client 66.6.145.214] Directory index forbidden by Options directive: /var/www/<mydir> [Thu Mar 08 14:05:56 2012] [error] [client 66.6.145.214] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /var/www/error/noindex.html [Thu Mar 08 14:05:57 2012] [error] [client 66.6.145.214] Request exceeded the limit of 10 internal redirects due to probable configuration error.

• 32 vs 64-bit software for same machine?

  - by GorillaSandwich

  What is the difference between 32 and 64-bit software? My understanding is that 64-bit can use more RAM, if it's available, because it has a larger address space for it. Is this correct? And, specifically: If I have a 64-bit operating system with lots of RAM, and I install, say, the 32-bit version of MySQL instead of the 64-bit version, will it be unable to use all the available RAM and therefore run slower than the 64-bit version might on the same machine (assuming RAM becomes the bottleneck before processing speed or disk access speed or whatever)? If I have a 32-bit operating system and I install a 64-bit piece of software on it, will it (probably) fail to run?

• Is there any way of preventing .csv files being converted into excel format

  - by Kevin Trainer

  I'm trying to work with an automated testing tool which can use .csv files as its data sourse. After saving a notepad file containing a number of fields and data seperated by commas as .csv it appears to have been converted to an excel file. When I run the test, only the first line of values is identified and can be run within the automated test. Not sure if this is expected with the testing product (www.badboy.co.au), but just wondered if there was a way of preventing excel from taking control of the .csv file? Any helpfull feedback would be great.

• One Windows Domain workstation can ping gateway but gets no internet access

  - by dindeman

  One of the (Windows XP SP3) workstations of our Windows Domain could not access internet anymore, this problem suddenly happened overnight. The domain controllers (there are three of them) are all running Windows Server 2008. First I compared the output of ipconfig /all on the faulty workstation with the output of a working workstation and it was just fine as it had always been. In particular the default gateway was correct and always remained pingable from the faulty workstation. I guessed that something was wrong with the DHCP service and I restarted the DHCP server service on all of our three DCs as well as the DHCP client service on the faulty workstation. This didn't solve the issue. I then thought of renewing the DHCP lease with ipconfig /release and ipconfig /renew and here is my first question: why did this never work? The same IP address (192.168.0.45) kept being assigned despite all my attempts to renew it (note that all our workstation are getting their TCP/IP automatically.) Even by leaving the domain and changing the computer name the same address was yet again obtained... Anyway I then proceeded to switch the TCP/IP configuration for that machine manually to another free valid IP address (192.168.0.41)... and then the internet access came back! I then cleared any traces of the previous IP in the DHCP leases list and in the DNS tables of our DCs and, after setting back the TCP/IP configuration to 'automatic', finally, the new lease would be granted (192.168.0.41) alongside with the internet access. My second question: what went suddenly wrong with the original IP address?

• Accessing the Local System Account to accept a software licence

  - by Ryan French

  Hi All, I have a server at the moment running ColdFusion which is being used to access a windows whois program on the server. Each time I call this command via ColdFusion (using cfexecute) the command times out. I believe the issue is because the first time a user runs the .exe file they are asked to accept the licence. ColdFusion is currently set to run under the Local System account and I am just wondering if it is possible to somehow log into this account and run the program manually via the console so that I can accept the licence. I guess my only other option is to change the account ColdFusion runs under, but I would rather not do this.

• Have servers behind OpenVPN subnet reach connecting clients

  - by imaginative

  I am trying to find some relevant documentation or what directives I need in either the OpenVPN server configuration or client configuration to accommodate for this use case. I have an OpenVPN server that clients connect to. The OpenVPN server can communicate directly with any of the clients already, this is not an issue. The client is able to reach any machine on the private subnet where OpenVPN resides, this is also not an issue. My issue is that the reverse is currently not possible - I have servers on the same subnet as the OpenVPN box that cannot reach any of the connecting clients. I'd like to be able to SSH to them and more, the same way the client can reach the servers behind the OpenVPN subnet. What do I need to do to make this possible? I already have masquerading rules set on the OpenVPN box: iptables -t nat -A POSTROUTING -s 192.168.50.0/24 -o eth0 -j MASQUERADE IP Forwarding is enabled: echo 1 >/proc/sys/net/ipv4/ip_forward I added a route on the server behind the private subnet to be aware of the route: 192.168.50.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 What am I missing?

• Upgrading PHP, MySQL old-passwords issue

  - by Rushyo

  I've inherited a Windows 2k3 server running an XAMPP-installation from the stone age. I needed to upgrade PHP to facilitate an upgrade to MediaWiki to facilitate a new MediaWiki extension (to facilitate some documentation to facilitate doing my job to facilitate getting paid to facilit... you get the idea). However... installing a new version of PHP resulted in PHP's MySQL libraries refusing to communicate using MySQL's 'old style' 152-bit passwords. Not a problem in theory. The MySQL installation is post-4.1, so it should have the functionality to upgrade the user's passwords from 152-bit to 328-bit (what a weird hashing algorithm...). I ran the following: SET PASSWORD = PASSWORD('foo'); on MySQL but querying: SELECT user, password FROM mysql.user; returned just the same password I started out with - 152-bit. Now... I suspect you're thinking 'AHA! old-passwords is on!'. Unfortunately it's not - I've disabled it in the configuration (explicitly set it to 0), made doubly sure I have an absolute reference to that configuration file and ensured the service isn't using the --old-passwords flag. The service was reset after each and every operation. So I went onto another system and generated the 328-bit hash on there, copying the hash over to the first MySQL instance. Unfortunately, that didn't work either (I did remember to FLUSH PRIVILEGES). The application error is: "'mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool [...snip...] Is there anything else I can try to get PHP to recognise MySQL as not using the 'old insecure authentication'? MySQL seems to be stuck in 'old-passwords' mode and I can't get it out of it.

• Small 64-bit linux server distro with low memory footprint?

  - by djangofan

  I am looking for a linux server distro with a low memory footprint. I usually use Ubuntu but I need something with a smaller footprint in order to run a large Java JVM service inside of it and also run X-windows. Any ideas? The Java service needs to handle a 3GB memory heap and so I require a 64-bit OS and JRE. http://en.wikipedia.org/wiki/Comparison%5Fof%5FLinux%5Fdistributions I am thinking that ArchLinux is the only one that I can find right now. It uses 250MB out of the box (without X-win). Any better suggestions?

• Writing Macros to find a specific cell and paste the value from a control cell into it

  - by G-Edinburgh

  I am having some issues writing a Macro to do the following. I have a very long list of rooms with two columns one containing the room number i.e. B-CL102 and the other containing a varying integer.I am looking to create a new column that will contain another different integer for each of the rooms. Is there any way to write a Macro so that I can use two control cells at the top of the sheet, type the room number into one and the integer matching that room into another, then run the Macro and it will automatically populate the correct cell. Then I can change the two values in the control cells and run the Macro again and so on. Thanks for your help, I have a very minimal amount of experience with Macros essentially just the basics. Thanks G

• cluster of services and restarting on package upgrade

  - by Marcin Cylke

  I'm using puppet to manage a bunch of servers. Those servers run a simple service - exposed to the world via load balancer. That service's instances are independent in that they can run on their own, are are deployed on multiple servers to increase responsiveness. Now, when I push a new package to repo and puppet catches up with it appearing there it just updates this package on all services. This results in a short downtime of entire service. Is there a way of configuring puppet to do restart the services sequentially? Or using any other kind of strategy?

• Intermittent apt-get 'no installation candidate' error on fabric deploy

  - by jberryman

  I'm experiencing a strange issue with a fabric script I'm using to bootstrap a server on EC2. I launch a stock Ubuntu 12.04 AMI, wait for it to start, then proceed with: with settings(host_string="ubuntu@%s" % i.dns_name, connection_attempts=30): sudo('apt-get -qy update') sudo('apt-get -qy install --no-install-recommends mdadm') # don't install postfix #etc... The apt-get update appears to run fine and gives no errors, however (2/3 of the time or so) installing mdadm throws a "no installation candidate" error. When I ssh into the server and run apt-get install mdadm I get the same error. Running apt-get update by hand, then the package installs fine. Any ideas on what might be happening, or ideas for debugging?

• Truecrypt system partion partially encryted but then drive corrupted and won't boot - decrypting so I can access files to backup?

  - by Dr.Seuss

  So I was attempting to encrypt my (Windows 7) system drive with Truecrypt and it stopped at around 15% and said that there was a segment error and that it could not proceed until it was fixed. So, I restarted the computer and ran HDD Regenerator which subsequently fixed the bad sectors on the drive, but now my system cannot boot. So, I run a number of recovery disks to no avail (Windows repair is unable to fix) and the drive won't mount on a linux version run from a CD because the drive is encrypted. So I tried mounting the drive using Truecrypt under the Linux distribution on the disk and selected "Mount partition using system encryption without pre-boot authentication" so I can decrypt, but I get an error message about it only being possible once the entire system is encrypted. How do I get out of this mess? I need to be able to back up the data that's on that partially encrypted drive so I can reinstall my operating system.

• How to enjoy DVD on Apple iPad

  - by user44251

  I believe many people spent a sleepless night yesterday waiting for the new Apple Tablet to come, just a few days ago or perhaps longer I noticed fierce debate about it, its name, size, capacity, processor, main features, price etc. And now, they can take a long breath with the new Apple Tablet named iPad officially released on 28, January, 2010 (Beijing Time). But I know a new battle just begins. iPad, sounds somewhat like iPod and it really shares some similarities in terms of shape like smart, light and portable. It has a 9.7-inch, LED-backlit, IPS display with a remarkable precise Multi-Touch screen. And yet, at just 1.5 lbs and 0.5 inches thin, it's easy to carry and use everywhere. It can greatly facilitates your experience with the web, emails, photos and videos. Right now, it can run almost 140.000 of the apps on the Apple store. It can even run the apps you have downloaded for your iPhone or iPod touch. But so far, I haven't seen any possibility that it can work with DVD, probability there is no built-in DVD-ROM or DVD player which can play DVD directly. As Apple iPad states, the video formats supported are MPEG-4 (MP4, M4V), H.264, MOV etc and audio formats accepted are AAC, Proteceted AAC, MP3, AIFF and WAV etc, those are formats that are commonly used with iMac. This could really a hard nut to crack if you want to watch your favourite DVD on this magic Apple iPad. But don't worry, there is still way out, you just need a few steps for ripping and importing DVD movies to Apple iPad with a simple application DVD to iPad converter What's on DVD to iPad Converter for Mac DVD to iPad converter for Mac is a powerful and professional application designed for the newly released Apple iPad which can rip, convert your DVD contents to Apple iPad compatible MPEG-4 (MP4, M4V), H.264, MOV etc, and other popular file formats like AVI, WMV, MPG, MKV, VOB, 3GP, FLV etc can also be converted so that you can put on your portable devices like iPod, iPhone, iRiver, BlackBerry etc. Besides, it can also extract audio from DVD videos and save as MP3, AIFF, AAC, WAV etc. Mac DVD to iPad converter has also been enhanced that can run both on PowerPC and Intel (Snow Leopard included). It can offer versatile editing features which allows you to make your own DVD videos. For example, you can cut your DVD to whatever length you like by Trim, crop off unwanted parts from DVD clips by Crop, add special effect like Gray, Emboss and Old film to make your videos more artistic. Besides, its built-in merging feature and batch mode allows you to join several DVD clips into a single one and do batch conversion. And more features can be expected if you afford a few minutes to try.

• Ubuntu 10.04 network manager issues

  - by Shark

  I was using the default network manager to connect to my wi-fi network, but if the connection is dropped or router restarted the network manager wont reconnect automatically after i guess a couple of tries and just gives a pop-up to connect manually . To avoid this annoyance I installed WICD but though it does try to reconnect to the network after a drop in connection it is unable to resolve the ip address and i am left with an even bigger annoyance . 1. Is there a way to counter either of these issues ? 2. Something like a background process that will check network status periodically and then try to connect to a favored network ?

• Windows 7 [virtualized] resolutions in Macbook Pro Retina

  - by Trevor Sullivan

  So, I was considering picking up a Macbook Pro Retina, but then I realized that Apple forces you to scale the resolution, so you don't actually see the true benefits of the 2880x1800 display. Instead, you see upscaled, pixelated icons -- I saw this for myself in an Apple store a couple days ago. That's ok though, because the main reason I'd purchase one is to run Windows 7 on it, however I understand that the bootcamp drivers have not been updated to work with the MBP Retina. Instead, the option would be to run Windows 7 virtualized, but I haven't found any conclusive evidence to indicate whether the entire 2880x1800 resolution would act the same virtualize (VMware Fusion, VirtualBox, Parallels) as running Windows 7 natively. My question is: Does Windows 7 see the entire 2880x1800 virtualized, same as running it on bare metal (boot camp)?

• Doesn't DNS diversity negatively affect performance? Why/how?

  - by cnst

  If you look at the press releases of various orgs that run the internet, you can see them praise the fact that now they run root server X in city Y, as if that magically makes everyone in city Y get all the relevant resolutions from the local server X, instead of going 200ms across the oceans and lands to other continents for resolutions. Similarly, the zones of some geographical domain names, like .ru, are being mirrored not just within Europe, but also, for example, in Hong Kong, which is no more, no less, but is about 300ms away from central Europe, since the traffic is often crossing the two oceans on each way. Doesn't all of this negatively affect DNS performance? Isn't it more of a liability to have a diverse pool of geodispersed authoritative servers, especially if your target audience is quite geographically concentrated? Perhaps a better question is, are there any DNS resolvers that use something better than the naive round-robin for choosing which authoritative server to contact?
