• Windows Bluescreen - atikmpag.sys

  - by Mochan

  Information Name: atikmpag.sys bluescreen (BSOD or BlueScreen of Death) Error code: 0x00000116 Appears when: Playing games, watching videos Can be reproduced: Yes Cause: Graphics Card is the main assumption System Specifications Before we begin - I will inform you of my specifications. OS: Windows 7 x64 Home Edition Model: Dell Inspiron 15R Special Edition (aka Inspiron 7520) (Add 2GB of RAM to the model linked) Hard Drive: 1TB CPU: Intel Quad-Core i7 Sandy Bridge (I think) Processor at 2.10GHz (I think it can be clocked to 3GHz?) RAM: 6GB (I think 1 x 4GB and 1 x 2GB) Display: 15.6" HD (1366x768) Graphics: AMD Radeon HD 7500M 2GB Details So now that you know some basics about my computer, I'll get to the problem. Being an Ubuntu user I hardly use Windows, but occasionally I do. Like to run Skyrim and other games incompatible with Linux and WINE. The new Sims 3 Seasons patch is also now not supported. When playing these two games and other ones, theoretically. I have also heard others saying that while watching HD movies and video series it also happens. While watching the bluescreen as it happens, I see it is the 'atikmpag.sys' error. I have not installed much and nothing significant. I think I have downloaded Skyrim, Firefox and The Sims 3. I haven't done much more... since Ubuntu is definitely the best in comparison! (No hate, just a joke :P). I can reproduce it easily (just by running a game for less than a minute). It is always there each time, but it's never at a specific time or anything. So far I have found that it may be caused by lack of power to the graphics card, or it may be damaged or fried. Since I've had the computer for a mere 4 months (and have had other problems with it also). I have contacted Dell but they are useless beyond belief. Anyone with any information, solutions or details are encouraged to share your knowledge, as it would be immensely appreciated.

• New router messed up server 2003 setup...

  - by Aceth

  Hey, We were sent a new 2wire router today configured it as best we can to match the old bt voyager. We've also got X static IP's. We've manage to get our webserver on one of the new IP's public facing. then we use a hardware firewall which is in a DMZ again with a different static IP. This firewall then is our gateway for our internal LAN. with a few servers etc. The problem we're having is only our PDC (primary Domain controller which has exchange 2003 on) can't ping externally even an external IP. We've connected laptops to the 2wire router and obtain a private ip 192.168.1.X and it works fine can ping etc. our other servers with an internal ip behind the firewall can ping out fine. We've connected to the firewalls logging console and the pings from the server are allowed through so its fine there. The server in question is a Windows server 2003 R2 Enterprise SP2 + Exchange 2003 Server doesn't have firewall turned on. it has static private IP .. gateway is pointing to the right one External Static IP is routing fine inwards We've ran out of ideas .. help??

• Does fast typing influence fast programming?

  - by Lukasz Lew

  Many young programmers think that their bottleneck is typing speed. After some experience one realizes that it is not the case, you have to think much more than type. At some point my room-mate forced me to turn of the light (he sleeps during the night). I had to learn to touch type and I experienced an actual improvement in programming skill. The most surprising was that the improvement not due to sheer typing speed, but to a change in mindset. I'm less afraid now to try new things and refactor them later if they work well. It's like having a new tool in the bag. Have anyone of you had similar experience? Now I trained a touch typing a little with KTouch. I find auto-generate lessons the best. I can use this program to create new lessons out of text files but it's only verbatim training, not auto-generated based on a language model. Do you know any touch typing program that allows creation of custom, but randomized lessons?

• How can I manage AWS VPC ssh access accounts and keys across multiple instances?

  - by deitch

  I am setting up a standard AWS VPC structure: a public subnet some private subnets, hosts on each, ELB, etc. Operational network access will be via either an ssh bastion host or an openvpn instance. Once on the network (bastion or openvpn), admins use ssh to access the individual instances. From what I can tell all of the docs seem to depend on a single user with sudo rights and a single public ssh key. But is that really best practice? Isn't it much better to have each user access each host under their own name? So I can deploy accounts and ssh public keys to each server, but that rapidly gets unmanageable. How do people recommend managing user accounts? I've looked at: IAM: It doesn't like like IAM has a method for automatically distributing accounts and ssh keys to VPC instances. IAM via LDAP: IAM doesn't have an LDAP API LDAP: set up my own LDAP servers (redundant, of course). Bit of a pain to manage, still better than managing on every host, especially as we grow. Shared ssh key: rely on the VPN/bastion to track user activities. I don't love it, but... What do people recommend? NOTE: I moved this over from accidentally posting in StackOverflow.

• How have multiple web servers and IPs on the same physical network

  - by jsigned

  I do web development out of a small office and need to have multiple physical and virtual servers that can be accessed from the internet. I also have a number of devices (computers, laptops, tablets, printers, etc) that need connections as well. I have gotten a subnet of 8 IP's from my ISP and while that is adequate for the web servers its far too small for everything that needs access to the network. My router is an ASUS RT-N16 running DD-WRT. I'm just smart enough about this routing topic to be dangerous, think 2 year old with a magic marker. I would like to keep my internal network NAT'ed on the 192.168.x.x network and route the 68.69.x.x 255.255.255.248 traffic directly to the servers. The physical network consists of the 4 port DD-WRT router and an unmanaged gig switch. I have a fiber connection to the office that works as an Ethernet port. In other words I can plug my laptop directly into it and have access to the internet. There is no login or password and the router is setup to get DHCP from the ISP, and to provide DHCP addresses for the internal network. What I've done so far is google and try different configurations with little success. In the end I decided I didn't even know how to ask the questions needed. My questions are: Is this the best way to configure the network? How do you do it? VLANs? Multiple routers? I've never had to configure a router using anything more than the GUI so if this is command line stuff be gentle.

• how to automatically mount ~/Private using ecryptfs when logging in via ssh pubkey

  - by andreash

  Raionale: I want to be able to automatically make backups to a remote machine, which will be encrypted with ecryptfs. The title says it all: I set up ecryptfs-utils on my Debian Squeeze box, and set up one user to use it via ecryptfs-setup-private. When I log in via SSH using password authentication, the ~/Private directory automatically gets mounted. How can I achieve that ~/Private also automatically gets mounted when logging in via SSH using public key authentication? Obviously, the best solution would be if ecryptfs could somehow 'use' the SSH public key to en/decrypt the data (I know that then using the user's password would not be able to en/decrypt the data any more; this would be acceptable). Probably, this will not work. So perhaps somehow call ecryptfs-mount-private via ssh before logging in via public key? Probably, then I would need to somehow pipe the passphrase through the SSH connection, right? So I would need to store it on the source machine's file system. Not nice either. Any other ideas?

• Will adding a SSD cache device to my ZFS storage improve performance?

  - by Sysadminicus

  The server has 4GB of RAM and my zpool is made up of 15.5k SAS drives arranged like this: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 c0t2d0 ONLINE 0 0 0 c0t3d0 ONLINE 0 0 0 c0t4d0 ONLINE 0 0 0 c0t5d0 ONLINE 0 0 0 c0t6d0 ONLINE 0 0 0 c0t7d0 ONLINE 0 0 0 c0t8d0 ONLINE 0 0 0 raidz1-1 ONLINE 0 0 0 c0t10d0 ONLINE 0 0 0 c0t11d0 ONLINE 0 0 0 c0t12d0 ONLINE 0 0 0 c0t13d0 ONLINE 0 0 0 c0t14d0 ONLINE 0 0 0 spares c0t9d0 AVAIL c0t1d0 AVAIL The primary use is as an NFS store for a couple VMWare ESXi servers. I can't do any "true" benchmarks because this is a production system (no budget for test systems), but using dd and bonnie++ I can't get more than ~40-50MB/s writes and ~70-90MB/s reads. It seems I should be able to do much better, but I'm not sure where to optimize. Based on what I've read, I think dropping in a OCZ Vertex 2 Pro SSD as my L2ARC is going to be the best bang-for-the-buck to improve througput. Is there something else I should be looking into to help performance? If not... How do I know how big a cache device I need? Am I safe with only a single SSD as my cache device?

• Usage of putty in command line from Hudson

  - by kij

  Hi, I'm trying to use putty in command line from an hudson job. The command is the following one: putty -ssh -2 -P 22 USERNAME@SERVER_ADDR -pw PASS -m command.txt Where 'command.txt' is a shell script to execute in the server through SSH. If i launch this command from the Window command prompt, it works, the shell script is executed on the server machine. If i launch a build of the hudson job configured with this batch command, it doesn't work. The build is running... and running... and running.. without doing anything, and i have to stop it manually. So my question is: Is it possible to launch an external programm (i.e. putty) from an hudson job ? ps: i tried SSH plugin but... not a really good plugin (pre/post build, fail status of the commands launched not caught by hudson, etc.) Thanks in advance for your help. Best regards. kij EDIT: These are the build logs: [workspace] $ cmd /c call C:\WINDOWS\TEMP\hudson7429256014041663539.bat C:\Hudson\jobs\Artifact deployer\workspace>putty -ssh -2 -P 22 USER@SERV_ADD -pw PASS -m com.txt Le build a été annulé Finished: ABORTED And the Hudson.err.log file at the same time (after a stop): 3 juin 2010 18:27:28 hudson.model.Run run INFO: Artifact deployer #6 aborted java.lang.InterruptedException at java.lang.ProcessImpl.waitFor(Native Method) at hudson.Proc$LocalProc.join(Proc.java:179) at hudson.Launcher$ProcStarter.join(Launcher.java:278) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:83) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:58) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:19) at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:601) at hudson.model.Build$RunnerImpl.build(Build.java:174) at hudson.model.Build$RunnerImpl.doRun(Build.java:138) at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:416) at hudson.model.Run.run(Run.java:1241) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:124) My shell script only write "hello" in a "hello.txt" file on the server, and nothing is done.

• Comparing Nginx+PHP-FPM to Apache-mod_php

  - by Rushi

  I'm running Drupal and trying to figure out the best stack to serve it. Apache + mod_php or Nginx + PHP-FPM I used ApacheBench (ab) and Siege to test both setups and I'm seeing Apache performing better. This surprises me a little bit since I've heard a lot of good things about Nginx + PHP-FPM. My current Nginx setup is something that is a bit out of the box, and the same goes for PHP-FPM What optimizations I can make to speed up the Nginx + PHP-FPM combo over Apache and mo_php ? In my tests using ab, Apache is outperforming Nginx significantly (higher requets/second and finishing tests much faster) I've googled around a bit, but since I've never using Nginx, PHP-FPM or FastCGI, I don't exactly know where to start PHP v5.2.13, Drupal v6, latest PHP-FPM and Nginx compiled from source. Apache v2.0.63 ApacheBench Nginx + PHP-FPM Server Software: nginx/0.7.67 Server Hostname: test2.com Server Port: 80 Concurrency Level: 25 ---> Time taken for tests: 158.510008 seconds Complete requests: 1000 Failed requests: 0 Write errors: 0 ---> Requests per second: 6.31 [#/sec] (mean) Time per request: 3962.750 [ms] (mean) Time per request: 158.510 [ms] (mean, across all concurrent requests) Transfer rate: 181.38 [Kbytes/sec] received ApacheBench Apache using mod_php Server Software: Apache/2.0.63 Server Hostname: test1.com Server Port: 80 Concurrency Level: 25 --> Time taken for tests: 63.556663 seconds Complete requests: 1000 Failed requests: 0 Write errors: 0 --> Requests per second: 15.73 [#/sec] (mean) Time per request: 1588.917 [ms] (mean) Time per request: 63.557 [ms] (mean, across all concurrent requests) Transfer rate: 103.94 [Kbytes/sec] received

• Hyper-V Virtual Machine Networking issues related to Max Ethernet Frame Size

  - by Goatmale

  I fixed an issue today earlier today but i'm interested in learning WHY it worked. We set up a new Hyper-V virtual machine only to discover that HTTP traffic wasn't working. HTTPS, pings, everything else was working fine. After months of prodding around I took a shot in the dark. On the Hyper-V host server, the physical NIC card had an advanced setting of "Max Ethernet Frame Size" set to 1500. After setting this setting to 1514 the issue was fixed. Alternatively, setting this to 1512 did not solve the issue; 1514 is the magic number. My best guess it that when this setting was set to 1500 it was allowing incoming pings because the data payload was a lot smaller of say, HTTP traffic. As far as HTTPS traffic, I read about something called "Path MTU discovery" which i'm going to assume why is HTTPs traffic was getting through fine, albeit slower. Looking at this post, people agree that 1518 is the max total frame size. Why didn't I need to change this to 1518 instead of 1514 bytes? Why is the default frame size 1500 if that's the max size of the Ethernet payload and not the max size.

• Apache2 VirtualHost on Debian not working

  - by milo5b

  I am having some problems with Apache2 configuration. I have already tried to look for documentation on the web (Apache's site, Debian's site, here on serverfault, etc), but nothing really helps. I have tried different configurations, but my current configuration is the following (/etc/apache2/sites-available/default): <VirtualHost *:80> ServerAdmin [email protected] ServerName mysite.dev ServerAlias mysite.dev DocumentRoot /var/www/mysite.dev/httpdocs/ ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> <VirtualHost *:80> ServerAdmin [email protected] ServerName livesite.com ServerAlias www.livesite.com DocumentRoot /var/www/livesite.com/httpdocs/ <Directory /var/www/livesite.com/httpdocs/> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> mysite.dev it's just an entry in hosts file on my client machine, while livesite.com it's an actual DNS record which would resolve to the same IP as the IP set in hosts file for mysite.dev. The problem is that when i try to type mysite.dev in my browser, it would automatically go to livesite.com. I tried to have different /etc/apache2/sites-enabled/ files (/etc/apache2/sites-enabled/mysite.dev , /etc/apache2/sites-enabled/livesite.com ) - and of course with the actual sites-available related files, but achieving the same results. I have tried to have a peak on error.log and access.log but there's nothing I can see. My httpd.conf contains: AccessFileName .htaccess And I have no /etc/apache2/conf.d/virtual.conf file. Any help would be greatly appreciated - if I did not provide enough info please let me know I will do my best to provide all necessary info. Thanks

• Error in Apache: /var/run/apache2 not found

  - by Julen

  This is more self-answered question but since it drove me crazy I would like to share with the community and maybe someone can tell me why it happened or what it caused. The thing is I wanted to install in my Ubuntu 10.4 machine a CGI app, one built in the samples that come with the gSOAP toolkit. My intention was to access those from ASP .NET machine. Regular Ubuntu does not come with Apache so I install it from Sypnatic. Pretty easy. I followed this How to Install Apache2 webserver with PHP,CGI and Perl Support in Ubuntu Server. Instead of apache.conf I tweaked httpd.conf since a college here used that file instead of the first to put his Apache running. Besides I was able to access his CGI from my ASP .NET but mysteriously I could not from mine, I was getting always "The request failed with HTTP status 503: Service Temporarily Unavailable". Checking Apache error.log I found these messages: No such file or directory: unable to connect to cgi daemon after multiple tries: /home/julen/htdocs/cgi-bin/calcserver And looking more carefully whenever I restarted Apache I got this other message No such file or directory: Couldn't bind unix domain socket /var/run/apache2/cgisock. cgid daemon failed to initialize I am pretty new with Ubuntu and I could not think that Apache and Synaptic made a mistake in the installation process of the server, but it is true that the /var/run/apache2 was missing whereas in my college's computer was not. I tried to find and "elegant" solution but I found a post from 2006 that had an slight reference to it. Finally I decided to create the folder myself (as root) and then everything worked fine. Hope this helps others if they encounter a similar problem. Still I have the doubt why the folders was not created in the first place. Best, Julen.

• Google chrome not accepting any security certificates

  - by Jerry

  I've recently developed a problem with Google Chrome that's really annoying. I'm using Firefox at the moment with no problems whatsoever and it's the same with IE, so it's safe to say this problem is specific to Chrome. The problem is that it's not accepting security certificates from certain sites. I suppose the best place to start would be google itself. I can't search. The google search page will load but when I type some search term into the search box and hit 'search' I get the message: "You attempted to reach www.google.com, but the server presented an invalid certificate. You cannot proceed because the website operator has requested heightened security for this domain." No matter what the search term is, this is the result. Also when I try to log in to facebook - same message. Youtube works and many other sites that I know present security certs so I'm baffled. I've searched and there are other people who have had similar issues but I can't find a solution anywhere. The most common answer I'm picking up for this is to "check your system time" but I can safely say that it's not my system time. If anyone knows what is going on, I'd very much appreciate being informed. It's not super urgent as I can use Firefox to access those places Chrome won't, but it IS super annoying because I can usually sort out issues like this in no time.

• VMware Workstation reboot 32-bit host when starting 64-bit guest

  - by Powerman

  I'm trying to start 64-bit guest (MacOSX and Windows7) on 32-bit host (Hardened Gentoo Linux, kernel 2.6.28-hardened-r9) using VMware Workstation (6.5.3.185404 and 7.0.1.227600). If VT-X disabled in BIOS, VMware refuse to start 64-bit guest (as expected). If VT-X enabled in BIOS, VMware start guest without complaining, but then, in about a second (I suppose as soon as guest try to switch on 64-bit) my host reboots (actually, it's more like reset - normal reboot procedure skipped and BIOS POST start immediately). My hardware is Core 2 Duo 6600 on ASUS P5B-Deluxe with latest stable BIOS 1101. I've power-cycled system, then enabled Vanderpool in BIOS. My CPU doesn't support Trusted Execution Technology, and there no way to disable it in BIOS. I've rebooted several times after that, sometimes with power-cycled, and ensure Vandertool is enabled in BIOS. I've also run VMware-guest64check-5.5.0-18463 tool, and it report "This host is capable of running a 64-bit guest operating system under this VMware product.". About a year ago I tried to disable hardened in kernel to ensure this isn't because of PaX/GrSecurity, but that doesn't help. I have not checked 32-bit guests with VT-X enabled yet, but without VT-X they works ok. ASUS provide "beta" BIOS updates, but according to their descriptions these updates doesn't fix this issue, so I'm not sure is it good idea to try it. My best guess now it's motherboard/BIOS bug. Any ideas?

• graphics performance better on battery?

  - by Scott Beeson

  Anyone have any idea why my laptop would perform (considerably) better while on battery than while plugged in? It's a Dell Latitude E6420 with Windows 8 Pro. I tried mirroring all the settings in the selected power plan from "On battery" to "Plugged In" and that didn't help. I then just restored the defaults for all power plans (balanced and high performance). I'm still seeing the same results. The best example where it is most noticeable (don't laugh) is Sim City Social in Chrome. I'm probably seeing a performance increase of 5x on battery versus plugged in. This is easily reproducible too. I'm very confused. Could it be caused by dust? The laptop isn't that old and there is no visible dust. I'm not going to take it apart to check the insides as it's a corporate laptop. Could it be overheating? Battery Sim City Social: 68 degrees max Civ V: 77 degrees max Charger Sim City Social: 68 Civ V: did not test See answer below... I'm retarded

• How to set up multiple DNS servers on an intranet

  - by Brent

  We have an Active Directory network, with a mixture of Windows DNS, linux BIND servers, and want to use OpenDNS as our external DNS provider. I am wondering What is the best way to set up these servers (regarding forwarders, recursion, etc.)? Active Directory is our main internal DNS for our domain, and has 3 redundant servers. DHCP and all our servers use these as their DNS servers. Then we have a legacy AD server from an old network that is still authoritative for a bunch of domains. Finally, we have a couple of Linux Bind servers that are authoritative for a bunch of websites we host. Should our main AD servers point to our legacy AD server, which points to one of our BIND servers, which points to the other BIND server, which finally points out to openDNS? Or should our main AD servers point to all of these directly? - or is there a better option? What happens if a domain is listed in 2 places? Does DNS process the forwarders in order? What about root servers - if I want to use OpenDNS for "everything else", do I just list them as the last forwarders, and delete the root servers from all my DNS servers? How does recursion work - in this scenario, should I be using recursion or not?

• SSL setup: UCC or wildcard certificates?

  - by quanza

  I've scoured the web for a clear and concise answer to my SSL question, but to no avail. So here goes: I have a web-service requiring SSL support for authentication pages. The root-level domain does not have the "www" - i.e., secure://domain.com - but localized pages use "language-code.domain.com", i.e. secure://ja.domain.com So I need at least a wildcard SSL certificate that supports secure://*.domain.com However, we also have a public sandbox environment at sandbox.domain.com, which we also need to support under localized domains - so secure://ja.sandbox.domain.com needs to also work. The previous admin managed to purchase a wildcard SSL certificate for .domain.com, but with a Subject Alternative Name for "domain.com". So, I'm thinking of trying to get a wildcard certificate with SANs defined as "domain.com" and ".*.domain.com". But now I'm getting confused because there seem to be separate SAN certificates, also called UCC certificates. Can someone clarify whether it's possible to get a wildcard certificate with additional SAN fields, and ultimately what the best way is to support: secure://domain.com secure://.domain.com secure://.*.domain.com with the fewest (and cheapest!) number of SSL certificates? Thanks!

• Is basing storage requirements based on IOPS sufficient?

  - by Boden

  The current system in question is running SBS 2003, and is going to be migrated on new hardware to SBS 2008. Currently I'm seeing on average 200-300 disk transfers per second total across all the arrays in the system. The array seeing the bulk of activity is a 6 disk 7200RPM RAID 6 and it struggles to keep up during high traffic times (idle time often only 10-20%; response times peaking 20-50+ ms). Based on some rough calculations this makes sense (avg ~245 IOPS on this array at 70/30 read to write ratio). I'm considering using a much simpler disk configuration using a single RAID 10 array of 10K disks. Using the same parameters for my calculations above, I'm getting 583 average random IOPS / sec. Granted SBS 2008 is not the same beast as 2003, but I'd like to make the assumption that it'll be similar in terms of disk performance, if not better (Exchange 2007 is easier on the disk and there's no ISA server). Am I correct in believing that the proposed system will be sufficient in terms of performance, or am I missing something? I've read so much about recommended disk configurations for various products like Exchange, and they often mention things like dedicating spindles to logs, etc. I understand the reasoning behind this, but if I've got more than enough random I/O overhead, does it really matter? I've always at the very least had separate spindles for the OS, but I could really reduce cost and complexity if I just had a single, good performing array. So as not to make you guys do my job for me, the generic version of this question is: if I have a projected IOPS figure for a new system, is it sufficient to use this value alone to spec the storage, ignoring "best practice" configurations? (given similar technology, not going from DAS to SAN or anything)

• Apache2: How to split out the SSL configuration?

  - by Klaas van Schelven

  In Apache2, I'd like to separately define my SSL-related stuff once, and in a separate file from the rest of the configuration. This is mostly a matter of taste, but it also allows me to include the rest of the configuration in my automatic deployment process. I.e.: current situation: # in file: 0000-ourdomain.com.conf (number needs to be low) <VirtualHost xx.xx.xx.xx:443> # SSL part SSLEngine on SSLCertificateFile ....crt SSLCACertificateFile ...pem SSLCertificateChainFile ...intermediate.pem SSLCertificateKeyFile ....wildcard.ourdomain.com.key SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown ServerName www.ourdomain.com ServerAlias ourdomain.com # the actual configuration, as found for xx.xx.xx.xx:80, repeated </VirtualHost> I'd like # in file: 0000-ssl-stuff <VirtualHost xx.xx.xx.xx:443> # SSL part SSLEngine on SSLCertificateFile ....crt SSLCACertificateFile ...pem SSLCertificateChainFile ...intermediate.pem SSLCertificateKeyFile ....wildcard.ourdomain.com.key SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown ServerName www.ourdomain.com ServerAlias ourdomain.com </VirtualHost> # in file: ourdomain.com.conf <VirtualHost xx.xx.xx.xx:443> # the actual configuration, as found for xx.xx.xx.xx:80, repeated </VirtualHost> Unfortunately, this does not seem to work. Apache SSL fails, though it does not give an error message at reload or syntax-check. My best found workaround is to us an Include directive from the 0000-ssl file. Many thanks!

• Cisco Pix 515 ip addressing

  - by Rickard

  I have just gotten my hands on a Cisco Pix 515 (not 515E) with 3 interfaces, and are just about to start some labs. In my lab, I am using a real life scenario from an actual setup at work. As I have no access to the device at work, I am simply trying to replicate the scenario by trial and error. At work, we are given two IP addresses from the provider, which is 1-to-1 nated addresses. The addresses we are allowed to use are: 10.131.35.4-5/29 Now, we have 3 servers on a DMZ, 192.168.2.2-4/24 and 17 client computers on 192.168.1.100-117/24 aswell as some static addressed devices on 192.168.1.8-18/27 My question is, how would I best set up so that the machines on the DMZ get's translated to 10.131.35.4 and the machines on 192.168.1.* will be translated to 10.131.35.5 I don't expect or want anyone to give me a fully functional config, I may learn from it, but I'd prefer to just have some advices or maybe a guide on how to set it up. I hope someone can shed some light over my situation, have been looking through google but I guess I don't the searchwords I'm using isn't too good as I can't find any good clues. THank you very much! PS. Maybe I should add, I am not unfamiliar with the Cisco CLI, as I prefer using that before any gui's. So not really looking for any solutions for the ASDM. DS.

• Protocol to mount fat32 network filesystem on Linux with ability to lock files ( not advisory locks

  - by nagul

  I have a fat32 filesystem sitting on a NAS storage device (nslu2) that I need to mount on my Ubuntu system. I've tried Samba and NFS mounts, but both don't seem to support proper locking. More specifically, I am unable to save files to the mounted drive through GNUcash, KeepassX etc, which makes the share fairly useless. Is there a protocol that allows me to achieve this ? Note that the NAS storage device is running a linux OS so I can run pretty much any protocol that has a linux implementation. The only option I'm not looking for is to reformat the partition to ext3, which I'm not able to do due to other constraints. Alternatively, has anyone managed proper locking of a fat32 system over the network using Samba ? Or, is advisory locking the best you get with a network-mounted fat32 file system ? I've thought of trying sshfs but I've not found any indication that this will solve my problem. Edit: Okay, maybe I can reformat the drive, but to any file system except ext3. The "unslung" nslu2 doesn't like more than one ext3 drive, and I already have one attached. So any solution that involves reformatting the drive to ntfs, hfs etc is fine, as long as I can mount it on linux and lock files.

• PostgreSQL 8.4 - Tablespace Optimization

  - by FloE

  I'm currently running a PostgreSQL Database with about 1.5 billion rows / 500 GB of data (including indices). There are several schemata: on for the (read only, irregular changes / updates) 'core-model' and one for every user (about 20 persons). The users can access the core and store data in their own schema, so everything is located in one database. The server runs with CentOS and PostgreSQL 8.4 and is used for scientific studies, exploration etc and is running quite well. These days an upgrade of the DB storage hard disks arrive - all with the same performance as the old ones. I'm looking for the best way to distribute the data on these disks. It would be possible to separate frequently used objects (the core-data) from the user schemata, but I'm not sure if this is really worth the effort. It seems to be a much better idea to move the WAL files (pg_xlog directory) to its own partition. http://www.postgresql.org/docs/8.4/static/wal-internals.html What are your opinions? Are there any tablespace- or partitioning-related performance documentations / benchmarks?

• eee box "drobpox" server 24/7

  - by microspino

  I'd like to create a mini dropbox and print server on a small soho network of 5 users (all of them use windows XP desktops). The device need to run 24/7 or at least 12/7 (I can accept just workday hours too but the other two options would be better). Dropbox mini server: I mean I will have a 90gb dropbox on every computer on my network LAN syncing with It and the one onto It syncing to the web. Print Server: I have a Samsung A4 small laser printer, a HP500 Designjet Plotter, a Samsung Multifunction Machine (fax/print/scan/copy), a modern HP color A3 Deskjet printer and a HP laserjet A4 color printer. All of them need to be connected to this mini server. Fax/Scan server: since I have the above mentioned fax/print/scan/copy machine I would like to make people use It from/to their computers through the mini server. I thought to a recent EEEBOX machine because I heard good things about ATOM cpus and because It seems that a recent BIOS version could switch It off and on autonomously. I'd like to listen some advice from You. Best of all would be: - If You have something similar running for a long time - If You disagree with this hardware choice and If You would suggest some other device. - If You see any issues with my printing setup - Anything else ;) My budget is from Zero (using right sw to build something on top on a old PC) to 500€ max.

• Limiting access in Silverlight\Pivotviewer

  - by sparaflAsh

  I'm going to deploy a pivotviewer application. As some of you might know this silverlight application load a .cxml index file for a group of images. My need is to make .cxml file and image files not accessible for the user. Now, if I don't have a need I usually code like this in C# and the file is hosted in the documentroot: _cxml = new CxmlCollectionSource(new Uri("http://www.myurl.it/Collection.cxml", UriKind.Absolute)); This means that my cxml and then the images are available by http for everyone who knows the URI. I'm a newbie to server configuration, so any help/hint would be deeply appreciated. Someone suggested me to take the files out of the root, but it seems like I can't go to pick them up if they are not a URL in Silverlight. At least I didn't managed to understand how. Someone else suggested me to play with web.config file to hide URLs, but I don't really know where to start. My question is, what's the best practice to hide my stuff? Obviously I can edit the question if you need more details.

• regsvr32 fails on Windows Server 2003 - LoadLibaray ("my.dll") failed

  - by John Mo

  The DLL in question is a VB6 web class. When deploying, the old one needs to be unregistered and the new one registered. This has worked for many years but has failed now with the following error in a message box: LoadLibrary("c:...\my.dll") failed - The filename, directory name, or volume label syntax is incorrect. I don't think there's a problem with the DLL being (un)registered because it's failing to unregister the existing DLL that was at one time successfully registered. I don't think there's a filename or path problem. Regsvr32 is executed using a batch file where the full path to the DLL is specified. The path has not changed. The batch file has not changed. The DLL has not changed (at least not the old one I need to unregister). It's a programming problem to me because I need to release an updated DLL, but I'm thinking it's maybe an admin problem best suited to the talents of the serverfault audience. I'm hoping somebody knows about a Windows Update or something that might hose regsvr32. Thank you.
