What used the linux memory? Low cache, low buffer, not a VM

- by Jason

First of all, yes, I have read LinuxAteMyRAM, which doesn't explain my situation. # free -tm total used free shared buffers cached Mem: 48149 43948 4200 0 4 75 -/+ buffers/cache: 43868 4280 Swap: 38287 0 38287 Total: 86436 43948 42488 # As shown above, the -/+ buffers/cache: line shows indicates the used memory rate is very high. However, from output of top, I don't see any process used more than 100MB of memory. So, what used the memory?

mod_proxy incorrect redirect behaviour

- by Kevin Loney

In chrome this configuration causes an infinite redirect loop and in every other browser I have tried a request for https://www.example.com/servlet/foo is resulting in a redirect to https://www.example.com/foo/ instead of https://www.example.com/servlet/foo/ however this only occurs when I do not include a trailing / at the end of the request url (i.e. http://www.flightboard.net/servlet/foo/ works just fine). <VirtualHost *:80> # ... RewriteEngine On RewriteCond %{HTTPS} off RewriteCond %{REQUEST_URI} ^/servlet(/.*)?$ RewriteRule ^(.*)$ http://%{HTTP_HOST}$1 [R=301,L] </VirtualHost> <VirtualHost *:443> # ... ProxyPass /servlet/ ajp://localhost:8009/ ProxyPassReverse /servlet/ ajp://localhost:8009/ </VirtualHost> The virtual host on port 443 has no rewrite rules that could possibly causing the problem, the tomcat contexts being referenced do not send any redirects, and if I change the ProxyPass and ProxyPassReverse directives to: ProxyPass / ajp://localhost:8009/ ProxyPassReverse / ajp://localhost:8009/ everything works fine (except for the fact everything from www.example.com is being passed to the proxy which is not the behaviour I want). I'm fairly certain this is a problem with the way I have my proxy settings configured because I did log all the rewrite output coming from apache and it was all correct.

NIS: which mechanism hides shadow.byname for unpriviledged users?

- by Mark Salzer

On some Linux box (SLES 11.1) which is a NIS client I can do as root: ypcat shadow.byname and get output, i.e. some lines with the encrypted passwords, amongst other information. On the same Linux box, if I run the same command as unpriviledged user, I get No such map shadow.byname. Reason: No such map in server's domain Now I am surprised. My good old knowlege says that shadow passwords in NIS are absurd because there is no access control or authentication in the protocol and thus every (unpriviledged) user can access the shadow map and thereby obtain the encrypted passwords. Obviously we have a different picture here. Unfortunately I don't have access to the NIS server to figure out what is happening. My only guess is that the NIS master gives the map only to clients conection from a priviledged port (1024), but this is only an uneducated guess. What mechanisms are there in current NIS implementations to lead to a behavior like the above? How "secure" are they? Can the be circumvented easily? Or are shadow passwords in NIS as secure as the good old shadow files?

what port should I open for mysql master-master replication?

- by Vanddel

I have two servers running php5-fpm and a load balancer running nginx, the three servers share /var/www/drupal using nfs. nfs is working correctly. I replicated the two servers' database using mysql master master replication. everything was working fine till I added my iptables rules. In my iptables script, I first drop all chains then I accept the ones I want, other than that there are no other drop statements. I opened port 3306 for mysql replication like this : (the rule is on both servers ) iptables -A INPUT -p tcp -s $ip_Of_Other_Server --dport 3306 -j ACCEPT iptables -A OUTPUT -p tcp -d $ip_Of_Other_Server --sport 3306 -j ACCEPT The problem is, when I run both servers and I try to log in using my account on drupal it doesn't log in although I find a successful log in attempt in drupal logs. When I run only one server of them I can log in normally. when I allow everything in my iptables rules it works normally. I believe there's some port I need to open using iptables for the replication to work correctly but I can't find which one to open.

Persistent Issues on small business network using Cisco 871W and Catalyst Express 500

- by Ben Campbell

Being the most qualified (read: still not qualified) to solve our persistant network issues, I've turned to serverfault for guidance. I've done some searching, reading related documentation on cisco.com and tried a bit of troubleshooting. Here is the config: 100mb synchronous connection from a business internet provider (tested multiple times at 100meg at the source) Cisco 871W wireless point & router is where the WAN connection starts (this serves all our wireless). The only wired connection in the 871W is the Catalyst switch listed below. Cisco Catalyst Express 500 (24TT) is where all the wired connections terminate. About 20 Windows workstations and servers (AD/Webservers only). Some services in EC2 including mail and other web servers/apps. I've been TOLD cabling internally should be gigabit-ready. Here are the problems: generally slow download rates from the internet to the desktop/laptop frequent "page cannot be displayed" errors in browsers-sometimes 3 or 4 reloads are necessary... often times CSS wont load or other content requiring the browser to connect to a different server. slow speed within the LAN from workstation to workstation copying files. I would expect extremely fast data transfer workstation to workstation / server to workstation in this simple network. Several things I need to admit: I'm not primarily a network guy. Funding is relatively low, I need to be the guy that finds the solution. I understand most of the terminology and most of the technology. Implementation is where I fail due to lack of experience. Getting to the point: I'm wondering whether experienced network admins think that our small network should be sufficiently served with our current hardware if configured properly... or if we should purchase new equipment and start fresh? If starting fresh is the plan, whatever that new equipment may be is a likely different question entirely. If I haven't provided enough information, I will happily do some troubleshooting and update with the results. I have experience using wireshark and some other tools. Please let me know what you think would be most helpful and thanks in advance. EDIT: I forgot to add that the Cisco applicance will not finish loading the SDM Express console. It hangs every time at the "populating modules... DHCP". It eventually crashes and closes. I've rebooted the hardware and this still happens.

What are the steps to set up a Hyper-V solution with one NIC

- by Cameron Aziz

I have successfully installed centos on a virtual machine via Hyper-V on Windows Server 2008 R2. This server has one NIC. I have created a virtual NIC, and virtual subnet, and within the virtual machine (via console) I can ping the gateway. But not google. Is there certain steps I am missing, I feel like I'm one setting away. Im not sure what other information would be useful. Here is the ipconfig of the host: Ethernet adapter vNIC losangeles1_1: Connection-specific DNS Suffix .. : IPv4 Address. . . . . . . . . . . : 10.10.0.1 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : Ethernet adapter Local Area Connection 2: Connection-specific DNS Suffix .. : IPv4 Address. . . . . . . . . . . : 72.51.43.43 Subnet Mask . . . . . . . . . . . : 255.255.255.192 Default Gateway . . . . . . . . . : 72.51.43.1

HT Link Sync Error after Ubuntu 10.04 LTS Installation

- by marklab

Update 1 I just assembled an exact replica of this server, and successfully installed Ubuntu 10.04 LTS in a RAID10 configuration. The success was confirmed by a login to the initial account. There must be a hardware component that is faulty. Since the error mentions HT, which I believe to be Hyper Threading, I will start with the CPUs. Please indicate if this error is more strongly associated with any other piece of hardware. Or make a recommendation of another approach that would be good for this issue. Issue I was attempting to install Ubuntu 10.04 LTS on this system with the board RAID10 configured. However, the installation failed at the partitioning stage by rebooting the system. Upon reboot, there is an error report after POST listing the following: Node0: NB WatchDog Timer Error Node1: HT Link Sync Error Node2: HT Link Sync Error ... Node7: HT Link Sync Error Press F1 to continue/resume. After pressing F1 the system will boot from the Ubuntu 10.04 LTS installation disc. However, it will fail at the same stage, and go through the same process from there. Hardware CPU: AMD OPTERON X12 6172 G34 2.1G 18MB Motherboard: Supermicro H8QG6-F HDD: WD Caviar Green 2TB 5.4K RPM Troubleshooting I disabled RAID10 on the system, and installed the Ubuntu on a single drive. It installed successfully. I then went back to a RAID10 setup and attempted to install on the system again, and was able to make it through the partitioning stage. However, upon reboot, the system reported: Error: file not found, and then booted me into the Grub Rescue console. I feel I have aggravated the problem at this point because when I attempted to install from the boot disc again, the system reboots upon hitting enter to even start the installation process. It does the same thing when trying to boot from an Ubuntu 11 disc. I have not been able to find any information on this HT Link Sync Error, which I feel may have started the problems I am experiencing now with the installation of the OS. I am also aware that Ubuntu is said not to be supported by the motherboard according to Supermicro's site. However, since I was able to install it successfully on a single drive, I do not believe it is incompatible. I would like to know a reason for why it's failing to install on/off.

Monitor connected with WiDi just shows a black screen

- by Pops

I have a Dell XPS 18 and want to use an external monitor with it. The monitor has VGA and DVI-D inputs. The XPS 18 has no video output ports, but it does support Intel WiDi. I have a Netgear P2TV2000 WiDi receiver, but it only has composite and HDMI outputs. I'm connecting the receiver to the monitor with an HDMI cable and an HDMI/DVI-D adapter. So, in short, the video path is: Computer → WiDi → WiDi receiver → HDMI cable → HDMI/DVI-D adapter → Monitor After setting all this up, I can't get anything to display on the monitor. At the moment I power the monitor on, I can see my desktop for a brief fraction of a second, and then everything goes black. All of the relevant drivers have been updated to the latest versions. When I use a different WiDi-enabled computer to connect to the same monitor, everything works fine. When I use the original computer and receiver to connect to a TV, everything works fine. It's only when I connect the original computer to the monitor I want to use that the connection fails. What could be going wrong here, and how can I get the video to work consistently?

How can I stream audio signals from various devices/computers to my home server?

- by Breakthrough

I currently have a headless home server set up (running Ubuntu 12.04 server edition) running a simple Apache HTTP server. The server is near an audio receiver, which controls a set of indoor and outdoor speakers in my home. Recently, my father purchased a Bluetooth adapter, which our various laptops and cellphones can connect to, outputting the music to the speakers. I was hoping to find a solution that worked over Wi-Fi, namely because it won't cost anything (I already have a server with an audio card), and it doesn't depend on Bluetooth. Is there any cross-platform (preferably free and open-source) solution that I can use which will allow me to stream audio to my home server, over my home network, from a wide variety of devices (laptops running Windows/Linux or cellphones running Android/BB/iOS)? I need something that works at least with Windows and Android. Also, just to clairfy, I want something that simply allows devices to connect to my server and output an audio signal without any action on the server end (since it's a server hidden away near my receiver). Any subsequent connection attempt should be dropped, so only one device can be in control of the stereo at once.

How to redirect all Internet traffic to OpenVPN Server

- by JuliaS

I have seen working solutions around the issue of forcing Internet traffic to go through the OpenVPN server but they are all done in Linux, all I want to know is how to add an entry to the route table in windows to make this happen. connectivity between the client and server is fine, my Windows 7 client can establish a connection to the Windows 2008 Server, but when established Internet traffic is still going from the local Windows 7 machine. Here are the details: Server: Windows 2008 Server with one NIC OpenVPN IP Address: 192.168.0.1 Local NIC IP Address (connects the server to the Internet): 10.242.69.107 Client: Windows 7 with one NIC OpenVPN IP Address: 192.168.0.2 ISP allocated IP Address: 10.0.8.2 (gateway 10.0.8.1) Server OpenVPN Config: dev tun ifconfig 192.168.0.1 192.168.0.2 secret static.key push "redirect-gateway def1" Client OpenVPN Config: remote xxx.xxx.com dev tun ifconfig 192.168.0.2 192.168.0.1 secret static.key I'm not an expert with adding routes...etc. I would be grateful if someone could let me know how to add this entry in my server/client route table.

Video card not detected on Lenovo T410 in Linux

- by wich

I have a T410 with an nVidia NVS 3100M, this is not a hybrid system, there is no Optimus. (No option in the BIOS for Optimus, lspci in linux as well as the Windows device manager only show the nVidia) Using lspci I see the GPU as a present device, however, I can not, for the life of me, get any video driver to work that will let me start an X session, every time X craps out with the error (EE) No devices detected. I have tried the nVidia binary blob, (with nvidia-config, made sure no nvidia support in the kernel), I have tried nouveau, I have tried nv, I have even tried generic vesa, nothing will work. When I compare the dmesg that I get when loading the nvidia kernel module, I see that it is missing some lines compared with another system that also has an nvidia card, specifically the line mentioning the GPU name (3100M) is not there. I have checked every option in the BIOS, there is nothing to control except for the BIOS video output port, which is set to the LCD panel. I have no idea anymore what the problem may be, or even how I can diagnose this problem further. Any help will be appreciated.

How to force certain traffic through GRE tunnel?

- by wew

Here's what I do. Server (public internet is 222.x.x.x): echo 'net.ipv4.ip_forward=1' >> /etc/sysctl.conf sysctl -p iptunnel add gre1 mode gre local 222.x.x.x remote 115.x.x.x ttl 255 ip add add 192.168.168.1/30 dev gre1 ip link set gre1 up iptables -t nat -A POSTROUTING -s 192.168.168.0/30 -j SNAT --to-source 222.x.x.x iptables -t nat -A PREROUTING -d 222.x.x.x -j DNAT --to-destination 192.168.168.2 Client (public internet is 115.x.x.x): iptunnel add gre1 mode gre local 115.x.x.x remote 222.x.x.x ttl 255 ip add add 192.168.168.2/30 dev gre1 ip link set gre1 up echo '100 tunnel' >> /etc/iproute2/rt_tables ip rule add from 192.168.168.0/30 table tunnel ip route add default via 192.168.168.1 table tunnel Until here, all seems going right. But then 1st question, how to use GRE tunnel as a default route? Client computer is still using 115.x.x.x interface as default. 2nd question, how to force only ICMP traffic to go through tunnel, and everything else go default interface? I try doing this in client computer: ip rule add fwmark 200 table tunnel iptables -t mangle -A OUTPUT -p udp -j MARK --set-mark 200 But after doing this, my ping program will timeout (if I not doing 2 command above, and using ping -I gre1 ip instead, it will works). Later I want to do something else also, like only UDP port 53 through tunnel, etc. 3rd question, in client computer, I force one mysql program to listen on gre1 interface 192.168.168.2. In client computer, there's also one more public interface (IP 114.x.x.x)... How to forward traffic properly using iptables and route so mysql also respond a request coming from this 114.x.x.x public interface?

SSH dynamic port forwarding, "Connection refused"

I am trying to do dynamic portforwarding using openssh through a remote computer following this command: ssh -D 6789 rohan@<remote_ip> -p <remote_port> This should set up a socks server on my comp as I assume.

Mplayer no sound when playing some movies

- by Ivan Peevski

Ok, that's a bit of a strange problem, that somehow crept into my system. It used to work fine. Here is the problem as far as I can identify it. When I try to play certain video files with mplayer, there is no sound. As far as I can tell, it is only an issue with ac3 and dts sound tracks (using the ffmpeg decoder). Mplayer says: ========================================================================== Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders AUDIO: 48000 Hz, 6 ch, s16le, 1536.0 kbit/33.33% (ratio: 192000->576000) Selected audio codec: [ffdca] afm: ffmpeg (FFmpeg DTS) ========================================================================== [AO_ALSA] Playback open error: Device or resource busy Failed to initialize audio driver 'alsa' Could not open/initialize audio device -> no sound. Audio: no sound (similar with ac3 sound, but using the ffac3 audio codec). Trying different audio output (-ao oss/pcm/sdl) doesn't fix the problem. The strange thing is that if I play these files directly with ffplay, they work fine. mplayer sound with mp3/ogg is fine My alsa configuration is standard (no /etc/asound.conf or ~/.asound*) OS: Linux Gentoo Mplayer: 1.0_rc4_p20100213 (SVN-r30554-4.3.4) FFMpeg: 0.5_p20601-r1 (SVN-r20601) Any other information I can provide?

Error applying iptables rules using iptables-restore

- by John Franic

Hi I'm using Ubuntu 9.04 on a VPS. I'm getting an error if I apply a iptables rule. Here is what I have done. 1.Saved the existing rules iptables-save /etc/iptables.up.rules Created iptables.test.rules and add some rules to it nano /etc/iptables.test.rulesnano /etc/iptables.test.rules This is the rules I added *filter # Allows all loopback (lo0) traffic and drop all traffic to 127/8 that doesn't use lo0 -A INPUT -i lo -j ACCEPT -A INPUT -i ! lo -d 127.0.0.0/8 -j REJECT # Accepts all established inbound connections -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # Allows all outbound traffic # You can modify this to only allow certain traffic -A OUTPUT -j ACCEPT # Allows HTTP and HTTPS connections from anywhere (the normal ports for websites) -A INPUT -p tcp --dport 80 -j ACCEPT -A INPUT -p tcp --dport 443 -j ACCEPT # Allows SSH connections # # THE -dport NUMBER IS THE SAME ONE YOU SET UP IN THE SSHD_CONFIG FILE # -A INPUT -p tcp -m state --state NEW --dport 22- j ACCEPT # Allow ping -A INPUT -p icmp -m icmp --icmp-type 8 -j ACCEPT # log iptables denied calls -A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7 # Reject all other inbound - default deny unless explicitly allowed policy -A INPUT -j REJECT -A FORWARD -j REJECT COMMIT After editing when I try to apply the rules by iptables-restore < /etc/iptables.test.rules I get the following error iptables-restore: line 42 failed Line 42 is COMMIT and I comment that out I get iptables-restore: COMMIT expected at line 43 I'm not sure what is the problem, it is expecting COMMIT but if COMMIT is there it's giving error. Could it be due to the fact i'm usin a VPS?My provider using OpenVZ for virtualizaton.

Are HDMI to VGA Adapters Really Device-Specific?

- by allquixotic

There are a lot of devices on the market right now (especially mobile devices) with a Micro-HDMI or Mini-HDMI port and no VGA or D-Sub output. Most manufacturers of said devices sell a cable that looks something like this: I have yet to find a cable like this that claims to work on a wide array of devices. In general, these cables claim to work with one specific device only. The way these cables work, I think, is that analog VGA signals are sent from the HDMI port on the device. This should work for devices that have special hardware on the motherboard/GPU capable of driving this. Is it the case that these cables have to be custom designed for each device? Or, is it rather that any device which possesses this special "signaling of analog VGA over the HDMI port" can be made to work with a cable that is physically compatible (i.e. the HDMI end plugs into the device and the VGA end accepts a VGA monitor cable)? Note that I am not looking for a product recommendation, just a conceptual clarification on what exactly these devices are doing. Also, a few remarks: The cables like the one depicted here are not digital to analog converters. I know about these: they are expensive, and they are the ONLY solution if your device only outputs a digital signal and is incapable of driving analog VGA over the HDMI port. The cables like the one depicted here are not straight crossover cables from VGA to HDMI, either. The crossover cables are designed to send a digital HDMI signal over the VGA port's wires; that is, the wire protocol is HDMI (digital) but the physical pinout is the same as VGA, even though nothing analog is happening. Once again, this is not the behavior that, I believe, the devices which I'm talking about in this question are doing. The cabling and devices that this question is about transmit the analog VGA data over the HDMI port (the HDMI port is in the device outputting the data, and the VGA side is the monitor/projector).

Running gdb on Ubuntu 9.10 Apache2 Install

- by AJ

Hi all, I am trying to run gdb to debug my Ubuntu 9.10 Apache2 install and having a couple of problems: It seems like the package installed by Ubuntu for Apache2 does not include debugging symbols; is there a different version of the package I should be using for developing/debugging? When I try to run gdb, I get an error that looks to be caused by some missing environment variable. Are there additional options I should pass to "run" to get this to work?

how to run multiple shell scripts in parallel

- by tom smith

I've got a few test scripts, each of which runs a test php app. Each script runs forever. So, cat.sh, dog.sh, and foo.sh, each run a php script, and each shell script runs the php app in a loop, so it runs forever, sleeping after each run. I'm trying to figure out how to run the scripts in parallel, and at the same time, see the output of the php apps in the stdout/term window. I thought, simply doing something like foo.sh > &2 dog.sh > &2 cat.sh > &2 in a shell script would be sufficient, but it's not working. foo.sh, runs foo.php once, and it runs correctly dog.sh, runs dog.php in a never ending loop. it runs as expected cat.sh, runs cat.php in a never ending loop *** this never runs!!! it appears that the shell script never gets to run cat.sh. if i run cat.sh by itself in a separate window/term, it runs as expected... thoughts/comments

Can't get Monit to work

- by Andrea

I am trying to configure Monit on my local machine to get a taste at how it works, but I have some issues. What I am trying to do is to get any evidence that Monit is up and running correctly and is actually monitoring something. So my /etc/monit/monitrc looks like set daemon 60 set logfile /var/log/monit.log set idfile /var/lib/monit/id set statefile /var/lib/monit/state set eventqueue basedir /var/lib/monit/events slots 100 set httpd port 2812 and allow username:password check process apache2 with pidfile /usr/local/apache/logs/apache2.pid start program = "/etc/init.d/apache2 start" stop program = "/etc/init.d/apache2 stop" if failed port 6543 protocol http then exec "/usr/bin/touch /tmp/monit" If I understand correctly, since apache does not listen on port 6543 (it is just a random number) I should get an error, and as a consequence the file /tmp/monit should be created. So I start monit by sudo service monit start sudo monit monitor apache2 Unfortunately no such file is created. Instead the web console shows an error for apache - execution failed. The log says 'apache2' failed to start. What am I doing wrong? EDIT As suggested in the comments, I ran monit in verbose mode, by monit -vv monitor apache2 (the exact command suggested in the comments failed). The output is Runtime constants: Control file = /etc/monit/monitrc Log file = /var/log/monit.log Pid file = /var/run/monit.pid Debug = True Log = True Use syslog = False Is Daemon = True Use process engine = True Poll time = 60 seconds with start delay 0 seconds Expect buffer = 256 bytes Event queue = base directory /var/lib/monit/events with 100 slots Mail from = (not defined) Mail subject = (not defined) Mail message = (not defined) Start monit httpd = True httpd bind address = Any/All httpd portnumber = 2812 httpd signature = True Use ssl encryption = False httpd auth. style = Basic Authentication The service list contains the following entries: Process Name = apache2 Pid file = /usr/local/apache/logs/apache2.pid Monitoring mode = active Start program = '/etc/init.d/apache2 start' timeout 30 second(s) Stop program = '/etc/init.d/apache2 stop' timeout 30 second(s) Existence = if does not exist 1 times within 1 cycle(s) then restart else if succeeded 1 times within 1 cycle(s) then alert Pid = if changed 1 times within 1 cycle(s) then alert Ppid = if changed 1 times within 1 cycle(s) then alert Port = if failed localhost:6543 [HTTP via TCP] with timeout 5 seconds 1 times within 1 cycle(s) then exec '/usr/bin/touch /tmp/prova-monit' timeout 0 cycle(s) else if succeeded 1 times within 1 cycle(s) then alert System Name = system_andrea-Vostro-420-Series Monitoring mode = active

IIS7 Session ID rotating with Classic ASP

- by ManiacZX

I am trying to migrate a Classic ASP app onto a Windows 2008 R2 server. The application features run fine, but I am having issue with session. The application keeps the logged in user information in session and I am constantly getting knocked out as if the session had expired. While debugging I have discovered the sessions are not expiring but instead I am getting 2-3 different Session IDs in use by one browser. I am outputting Response.Write(Session.SessionID) on various pages in the application and I can sit there and hit refresh over and over and watch the number changed between these 2-3 SessionIDs randomly. The sessions are still valid because when I refresh and get the Session ID that I logged in under the page is displayed (because the security check was successful) and when I get one of the other Session IDs I get the "you aren't logged in, you need to log in" message. If I close and re-open the browser, same story just the set of IDs are new. This happens with IE8, Firefox and Chrome from multiple computers. Things I've tried: - AppPool set to No Managed Code and Classic - Output Caching set .asp to never cache - ASP Session Properties enabled and disabled asp session state and confirmed it affected page (error trying to read Session.SessionID when disabled) Things I've tried just in case but shouldn't have anything to do with ASP Session: - Disabled compression - Changed ASP.Net Session State properties (InProc, StateServer, SQLServer, Cookies, URI, etc) -

Cannot set up dual monitors correctly in Fedora15 with KDE.

- by adivasile

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

nginx starts up before apache

- by paullb

I've been fumbling through setting up redmine on a unbuntu (12.04) box and somewhere along the line NginX got set up and now apache no longer loads because nginx has already grabbed the port. I tried removing NginX with the below command but that didn't seem to make any difference. When I restarted the server and pointed my web browser I still got the "Welcome to NginX" message sudo apt-get purge nginx I have confirmed that NginX is gone because when I run the above now I get as an output Package nginx is not installed, so not removed Yet everytime I start the machine it is running again. I noticed the following for the running processes (if that is helpful) root 923 0.0 0.0 76784 1280 ? Ss 03:00 0:00 nginx: master process /usr/sbin/nginx www-data 925 0.0 0.0 77092 1704 ? S 03:00 0:00 nginx: worker process www-data 926 0.0 0.1 77092 2204 ? S 03:00 0:00 nginx: worker process www-data 927 0.0 0.0 77092 1704 ? S 03:00 0:00 nginx: worker process www-data 928 0.0 0.0 77092 1704 ? S 03:00 0:00 nginx: worker process Any advice for bringing back apache2 as the "default" (for lack of a better term) web server?
