• How do I fake 2 discrete monitors using a DualHead2Go?

  - by Sietse

  I just got a [Matrox Dualhead2Go|http://www.matrox.com/graphics/en/products/gxm/dh2go/] for use with my MacBook Pro. I realise that the reason it works is that it fakes 1 big (wide) monitor. I also kind of depended on the software that came with it to trick OSX into accepting it as 2 monitors. Turns out the support is kind of lame: it just adds shortcuts for maximizing the window to whatever screen you want. And it even gets that wrong, since my dock doesn't auto-hide, but it doesn't take it in account while resizing, causing my window do end up "behind" my dock. (I've made a AppleScript that does the resize correctly, that I'll post below). There's two glaring issues this causes: Full screen (video, etc.) takes up both monitors, and dialogs just pops up in the middle. Is there a way to trick OSX, or at least a way to fix these issues?

• Ubuntu and mysql server. Something isnt allowing me to connect

  - by acidzombie24

  I have a question about mysql settings http://serverfault.com/questions/94054/remote-connections-and-mysql-on-ubuntu/94088#94088 now i want to figure out why i cannot connect. I made sure bind-address was commented out. I can ping the server within the VM but i cannot ping it from within the VM using mysqladmin --protocol=tcp --host=self_ip ping. I also followed along and check if my ports were open and they look like they are. I setup samba on that VM and can access that with no problem as well. It looks like ubuntu does not have a firewall either (i figured this out before) so i am stumped why the server isnt allowing my connection. Apparently the config file works on another person side http://www.pastie.org/742545 I am using Ubuntu 6.06 LTS just because of 'support' reasons. So hopefully this will be 'easy'?

• Get OWA and ActiveSync working on server using HTTP redirect in IIS 7

  - by eric

  We have two servers on our LAN. One is a Windows 2003 Server domain controller running Exchange 2003. The other is a stand-alone Windows 2008 server running IIS 7. Our company website runs on the IIS 7 (2008) server, so the firewall forwards port 80 to this. How can I get OWA and ActiveSync to work with this setup? And without using SSL. I have tried setting up a website on the IIS 7 box (mail.ourdomain.com) and using HTTP redirect to point to http://mailserver/exchange, but this doesn't work. Do we have to purchase an SSL certificate for this to work?

• How to install OSX into VirtualBox on a Macbook Air using Apple's Reinstall USB

  - by eug

  I'm currently dual-booting OSX and Ubuntu on my Macbook Air, but it'd be nice to run OSX within Ubuntu via VirtualBox. This seems possible using VirtualBox and is legal - there's even a post on an Oracle blog describing this: http://blogs.oracle.com/karim/entry/installing_mac_os_x_in. Actually, I've read elsewhere that it's only legal with OSX Server, but can't find a reason why it'd be illegal with normal OSX - please let me know if you think otherwise. The problem I have is that a MacBook Air doesn't come with a bootable DVD, but with a "Reinstall Drive" which is a USB stick that comes up as a CDROM drive. It doesn't seem to be ISO9660-formatted though but has an Apple partition table, with OSX installed on an HFS partition. refit says that it has a "boot.efi" as well. I don't know Apple booting/partitioning very well and would really appreciate some advice on how to convert this USB into an ISO or boot it in VirtualBox some other way.

• new vhost - main host AWstats

  - by vn

  Hi, I just began working at this new job and I have to config a new host for stats with awstats. I once used awstats on my own server, no biggie. Now, I'm on a multi-sites server with the acces_log files nicely splitted. I copied a awstats.conf file from one of the sites that already has (working) stats. I changed the LogFile and SiteDomain values as mentioned from http://awstats.sourceforge.net/docs/awstats_setup.html#BUILD_UPDATE, saved the conf and ran the commands perl awstats.pl -config=mysite -update and perl awstats.pl -config=mysite -output -staticlinks awstats.mysite.html (yes I changed it with my infos...) PROBLEM IS : whenever I try to access the html file or the dynamic page (with the config option on awstats.pl like my working site does), I get the stats of the MAIN site from access.log itself (and not access_log-mysite) from what it says at the top of the page and from the hostname on the left tab (stats for mysite.com)... what did I do wrong? There's no errors from what I see... Thanks a lot for any help

• Replicating EFS encrypted files

  - by floyd

  Recently I attempted to configure Microsoft's DFSR on Windows 2008 R2 to replicate a folder which was encrypted with EFS. The setup gave no errors or warnings, but later I read that DFSR does not support EFS in any way. There were also event logs in the DFSR event log indicating an encrypted file was found and wont be replicated. http://technet.microsoft.com/en-us/library/cc773238(v=ws.10).aspx#BKMK_052 My question is, are there any tools that would allow this to occur? Software based preferably.This would be replicating over LAN to destination node for two servers on the same domain.

• Connection Reset by Peer error with Apache and JBoss 7.1.1

  - by vikingz

  We are seeing errors on some of our QA testing scripts that intermittently throw Connection Reset By Peer errors. The Test scripts submit requests via F5 which forwards requests to Apache (2.2.21) with a mod_jk load_balancer with the following setting for each worker in the worker.property worker1 props worker.worker1.type=ajp13 worker.worker1.port=8109 worker.worker1.lbfactor=1 worker.worker1.host=skunkhost1.com worker.worker1.connection_pool_timeout=30 and here is what is in the JBoss domain.xml for the AJP port from JBoss 7.1.1 <unbounded-queue-thread-pool name="SKUNKY.APP.AJP"> <max-threads count="300"/> <keepalive-time time="3" unit="minutes"/> </unbounded-queue-thread-pool> Here is httpd.conf Timeout 300 KeepAlive On KeepAliveTimeout 15 MaxKeepAliveRequests 100 TraceEnable Off My question is that is it posisbe that apache times out and closes the connection while jboss is still ready and working on the request? What might be causing the Connection Reset By Peer error?what am i missing here? Any help is majorly appreciated!! Sincerely KK

• Mod_rewrite not working on ISPConfig 3 Server

  - by Akahadaka

  Problem I recently migrated a Drupal site from a shared hosting server to my own VM. Everything appears to work correctly, except clean urls. My VM Setup Ubuntu 10.04 LAMP ISPConfig 3 What I've tried From reading up on a number of drupal forums I've tried the following in this order Check that mod_rewrite is installed and enabled Changed PHP from FastCGI to Mod_PHP (prefer to use FastCGI or suPHP though to avoid having tmp/files folders with 777 permissions) Changed the Redirect type to L in ISPConfig Sites-domain.com-Redirect Changed /etc/apache2/sites-enabled/000-default <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride All ... </Directory> Not sure about points 3 and 4, I do want all domains to be able to use mod_rewrite out of the box. Question Have I done something wrong or am I missing a step? Ultimately I would like to use FastCGI and clean urls working on all ISPConfig 3 domains without having to make any changes to individual domain settings. Any ideas appreciated, I'll try them all.

• Is it possible to choose the Amazon Glacier Vault when backing up from Synology NAS?

  - by Jorrit Reedijk

  I am using Amazon Glacier Backup on a Synology NAS (rackstation). But the Synology backup software for glacier does not allow me to choose the vault to backup to. This means I can not give my own name to the vault, but also I can not backup to a previously created vault (I also have this problem now after replacing a Synology rackstation). Is there any way to choose to which vault you want your Synology to backup to? Edit: I have now posted this question to the Synology forum also: http://forum.synology.com/enu/viewtopic.php?f=174&t=86557&e=0 If I can solve the problem I'll post the solutions here also.

  - by David

• Brand new Lenovo u410 heats up around touchpad

  - by Ali

  My Lenovo u410 started heating around the right palm rest minutes after I unpacked it! I am devastated, because I bought this for programming, and it's impossible to type on this for extended periods with the surface getting so hot. I haven't run any serious programs on it yet, so the processor has been pretty much idle. I've been Googling this problem, and found only one person who had this issue too. Is this is a defect in the product? Why aren't many others getting this problem? I bought it via newegg.com and as per their policy you can't return a product once you've opened it. Specs: Core i5, 6 GB RAM, 750 GB harddisk. Running Windows 8.

• Remove iTunes on Mac OS X permanently: no Software Update

  - by ShreevatsaR

  Somewhat predictably, removing iTunes on Mac OS X is a long arduous process, described at http://support.apple.com/kb/ht1224 — which I have followed. As far as I can tell, I have purged every trace of the accursed iTunes from my system. Yet Software Update repeatedly prompts me with updates for iTunes, which I don't want anything to do with, despite my saying "Not now" each time. How can I convince Software Update to leave me alone, and never bother me with mention of iTunes again? I'm on Mac OS X 10.6.4 Build 10F569, and the update being offerred is iTunes 9.2.1. (Note: Not a duplicate of OS X: why Software Update suggests to update removed application?, whose accepted answer is simply to follow the instructions I mentioned above.)

• Dummy HTTP server for debugging

  - by Andrea

  This is more or less the inverse of my previous question. I need to debug some HTTP requests that I am making. Since these requests arise from the use of some external libraries, sometimes I am not sure of what is the actual data I am sending. Is there some dummy server (for Linux) that accepts HTTP requests and just prints them somewhere so that I can inspect them? I would like to be able to see in plain text the full request, like POST /foo HTTP/1.1 Host: www.example.com Accept: text/xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Language: en-gb,en;q=0.5 Content-Type: text/plain Content-Length: 11 Hello world

• disable "SSL 2.0+ upgrade support" in nginx

  - by Bhargava

  I evaluated the SSL credentials of my server with qualsys ssl page ( https://www.ssllabs.com/ssldb/index.html ) and found the entry "SSL 2.0+ upgrade support" being marked as yes. I want to disable this sslv2 handshake too. I searched around and found http://forum.nginx.org/read.php?2,104032m, which points to creating a openssl.cnf file. Have a naive question here. After creating the file, does one need to re-key his certificate for this to work ? Are there any other steps to follow ? I use nginx 1.0.11 and openssl "OpenSSL 1.0.0e-fips 6 Sep 2011". I have set ssl_ciphers in nginx to SSLv3 TLSv1;

• DNS and IPs - Does DNS send the IP back to the client?

  - by Josh

  I ran across a site that talked about routing all cients requesting by IP to a "dead end." The clients accessing the site via ip it claimed were typically automated exploit tools and bots. Legitimate users type in the web address by it's domain question. With this context in mind, I don't really understand how DNS really works. I thought it worked by sending an IP back to a client for the requested DNS (like a phone book.) The client then uses the IP to access the site. The information above seems to indicate I misunderstand this. Can someone clarify this? (http://technet.microsoft.com/en-us/magazine/2005.01.hackerbasher.aspx)

• Difference between tcp recv buffer and tcp receive window size?

  - by pradeepchhetri

  The command shows the tcp receive buffer size in bytes. $ cat /proc/sys/net/ipv4/tcp_rmem 4096 87380 4001344 where the three values signifies the min, default and max values respectively. Then I tried to find the tcp window size using tcpdump command. $ sudo tcpdump -n -i eth0 'tcp[tcpflags] & (tcp-syn|tcp-ack) == tcp-syn and port 80 and host google.com' tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 16:15:41.465037 IP 172.16.31.141.51614 > 74.125.236.73.80: Flags [S], seq 3661804272, win 14600, options [mss 1460,sackOK,TS val 4452053 ecr 0,nop,wscale 6], length 0 I got the window size to be 14600 which is 10 times the size of MSS. Can anyone please tell me the relationship between the two.

• Is there a command line two-factor authentication verification code generator?

  - by dan

  I manage a server with two-factor authentication. I have to use the Google Authenticator iPhone app to get the 6-digit verification code to enter after entering the normal server password. The setup is described here: http://www.mnxsolutions.com/security/two-factor-ssh-with-google-authenticator.html I would like a way to get the verification code using just my laptop and not from my iphone. There must be a way to seed a command line app that generates these verification codes and gives you the code for the current 30-second window. Is there a program that can do this?

• How can I scrape specific data from a website

  - by Stoney

  I'm trying to scrape data from a website for research. The urls are nicely organized in an example.com/x format, with x as an ascending number and all of the pages are structured in the same way. I just need to grab certain headings and a few numbers which are always in the same locations. I'll then need to get this data into structured form for analysis in Excel. I have used wget before to download pages, but I can't figure out how to grab specific lines of text. Excel has a feature to grab data from the web (Data-From Web) but from what I can see it only allows me to download tables. Unfortunately, the data I need is not in tables.

• mod_proxy failing as forward proxy in simple configuration

  - by Stabledog

  (On Mac OS X 10.6, Apache 2.2.11) Following the oft-repeated googled advice, I've set up mod_proxy on my Mac to act as a forward proxy for http requests. My httpd.conf contains this: <IfModule mod_proxy> ProxyRequests On ProxyVia On <Proxy *> Allow from all </Proxy> (Yes, I realize that's not ideal, but I'm behind a firewall trying to figure out why the thing doesn't work at all) So, when I point my browser's proxy settings to the local server (ip_address:80), here's what happens: I browse to http://www.cnn.com I see via sniffer that this is sent to Apache on the Mac Apache responds with its default home page ("It works!" is all this page says) So... Apache is not doing as expected -- it is not forwarding my browser's request out onto the Internet to cnn. Nothing in the logfile indicates an error or problem, and Apache returns a 200 header to the browser. Clearly there is some very basic configuration step I'm not understanding... but what?

• DKIM for email through Google Apps domain with external outbound relay

  - by David Gardiner

  I'd like to enable the new Domain Keys DKIM email authentication feature for a domain hosted in Google Apps. Some of my users use an external SMTP gateway (such that when they send email, it doesn't go through smtp.gmail.com). I have an SPF record configured for the domain, and this allows the external SMTP gateways as valid SMTP hosts. (I realise SPF is different to DKIM) Will enabling DKIM adversely affect the external gateway email? eg. Are the externally sent emails at risk of being marked as spam because they would not have the DKIM signature, or will DKIM only positively benefit emails sent through Google's SMTP server?

• Google Talk and Video outside of GMail

  - by mankoff

  I'd like to use Google Talk/Video with having the full gmail or igoogle interface displayed. The ideal setup would be the lightweight popout interface (link below) in a small Fluid.app single instance browser as a stand-alone desktop app. If I log into GMail, the chat sidebar has a phone icon so I can use Google Voice, and a camera icon next to me and some of my contacts. If I log into iGoogle, the chat sidebar has a camera next to me and some contacts, but no phone. I would like to have video chat (and perhaps the phone option) elsewhere. Google provides a chat talkgadget popout URL: http://talkgadget.google.com/talkgadget/popout but there is no phone or camera icon accessible.

• Where can I find old versions of linksys router firmware?

  - by Doug T.

  Hello everyone, I've had a headache of a weekend after upgrading to the latest firmware for my wrt54g. Suffice it to say I'm not satisfied with the latest version. Now I'm looking around for the previous version of the firmware out there on the interwebs and am having trouble. I noticed that linksys at one point had an ftp site: ftp://ftp.linksys.com. There you could find old firmware for your device. It now appears defunct. Does anyone know where I could find old firmware versions for my wrt54g router?

• Can I connect an external antenna to a range extender?

  - by ercan

  I live in a kind of dormitory and the next access point is 60 meters away from my room. So I bought a range extender (TP-Link WA730RE) and installed it into my room in the same height as the access point. But my problem is still not solved. The reception is slightly better but my connection still gets broken every two minutes. The antenna that comes with this range extender was 4dB. My question is, can I buy an 8dB external antenna (like this one: http://www.amazon.com/TP-Link-TL-ANT2408C-Desktop-Omni-Directional-Antenna/dp/B0034CQSKW/ref=sr_1_14?ie=UTF8&qid=1332074993&sr=8-14) and replace it with the antenna that comes with the range extender? Or is this external antenna only suitable for the "receiver" end of the connection, i.e. the computer?
