• How do I know if I have KMS enabled?

  How can I check if KMS is enabled in my kernel? I've compiled mine with KMS radeon modeset defaulting to 1, but I still suspect that it is not enabled.

• Graphite Running using daemon tools getting defunct

  - by pradeepchhetri

  I am running carbon-cache.py and carbon-aggregator.py using daemon tools.

• PureFTPd : ChrootEveryone not working

  - by Mistha Noobstha

  I have a fresh install of Ubuntu 12.04 with pure-ftpd version 1.0.35-1. I don't use database for the only user I have (ftpuser1 - localuser), but I want to lock him into his home directory. /ftp/ftpuser1 is the home dir of ftpuser1. /etc/pure-ftpd/conf/ChrootEveryone has the yes string and in /etc/default/pure-ftpd-common VIRTUALCHROOT is set to false, but ftpuser1 can freely walk around. My startup line for pure-ftpd looks like this : /usr/sbin/pure-ftpd -l pam -A -8 UTF-8 -O clf:/var/log/pure-ftpd/transfer.log -u 1000 -E -B So there is the "-A" in it for the ChrootEveryone.

• Serving static files fails - nginx

  - by Sergei

  Hi, I've been looking and trying around all night, but without success. I configured nginx to serve my static files and proxy all the other traffic: server { listen 80; server_name mydomain.com; access_log /home/boudewijn/www/bbt/brouwers/logs/access.log; error_log /home/boudewijn/www/bbt/brouwers/logs/error.log; location / { proxy_pass http://127.0.0.1:8080; include /etc/nginx/proxy.conf; } location /media/ { root /home/boudewijn/www/bbt/brouwers/; } } The proxy passing is no problem, but when I go to mydomain.com/media/ or try to access any testfile over there, it's without success. I paid attention to the difference between root and alias, my media folder exists, I paid attention to the trailing slashes, but still I get a 404 when trying to access my static media files. Any help?

• Logon script in Active Directory

  - by tareq838

  I am having a weird intermittent issue for only some users. I have a logon script that maps shared drives and issues a diisclaimer everytime the user logs on to a machine. The problem lately is that the logon script will not run for the user so we get a help desk call. When one of the help desk techs log on to the machine the script then comes up. The tech then logs off and the user will log back in and they will get the logon script. I am at wits end with this issue. Any help would be appreciated. It has happend on both Windows XP and Vista 64.

• Issue with Reporting Services - rsreportserver.config is denied

  - by Gabe

  Error message is 'd:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer\RSReportServer.config' is denied.' I open SSRS configuration and I do see the service as started and running. I gave Network Services the necessary permissions in the reportserver folder and config file. SQL Server and SSRS are using LocalSystem as the 'Log On As' in Sql server configuration manager. Most of my sites I googled seem only relevant when it's Network Service running. I changed it to log on as NT Autority\NetworkService but still had the same issue. In SSRS Config Manager, I see that Web Service Identity is not configured (red), though it is showing as readonly domain\aspnet. Windows Server 2003 R2 and SSRS 2005

• Mounting an encrypted partion Error

  - by indiajoe

  Using the disk utilities in ubuntu 11.04, i had encrypted a partition with a passphrase. Each time i used to click on the partition to mount, it used to ask me the passphrase and get mounted. All was fine, until i installed the 12.04. After the installation, this encrypted partition, disappeared from the menu. fdisk -l /dev/sda Shows the encrypted partition in the list /dev/sda7 298953648 488392064 94719208+ 7 HPFS/NTFS/exFAT I tried the following commands to mount it. But they all gave following errors $ sudo cryptsetup luksDump /dev/sda7 Device /dev/sda7 is not a valid LUKS device. $ ecryptfs-unwrap-passphrase /dev/sda7 Passphrase: # i entered the correct passphrase here... Error: Unwrapping passphrase failed [-5] Info: Check the system log for more information from libecryptfs $ grep ecryptfs /var/log/syslog Oct 31 22:43:51 benny ecryptfs-unwrap-passphrase: Error attempting to open [/dev/sda7] for reading Nov 1 01:28:02 benny ecryptfs-unwrap-passphrase: Error attempting to open [/dev/sda7] for reading Nov 1 01:29:06 benny ecryptfs-unwrap-passphrase: Error attempting to open [/dev/sda7] for reading I don't understand why I am getting the "Device /dev/sda7 is not a valid LUKS device." Could it be due to some corruption in partition table? Is there any way to recover this encrypted partition? Thanks indiajoe

• Exim - Sender verify failed - rejected RCPT

  While checking on Exim's log messages I found many entries of the following message "Sender verify failed" "rejected RCPT" ... I 'm not an exim expert... I'm afraid Exim is not delivering 100% emails to recipients, because our Email Marketing Application its getting a lower OPEN RATE. Can someone helpe understand this log messages?

• Strange permission errors with Windows Server 2008

  - by Spirit

  I just don't know a better way to describe my issue that is driving me nuts. I am trying to establish a test domain with virtual machines on a box that has Win7 with VMwware workstation installed. The purpouse with this domain will be so that we can try and test different situations before they go into the production network. I build a VM with WinSrv2008R2 and I am using that VM as a template to make other servers for the domain by making clones of it. Now I raise a DC with one clone and a member server with another clone - I add the server to the domain. I am following a standard procedure as always (it is not my first domain). Then I make an admin account and I am adding the admin to be a member of the Domain and Enterprise Admins group. That admin is admin with full priviledges on the DC.. no problem there. But on the other server has ... somewhat half the privileges and I cant log in via RDP. I tryed with another account. Same issues. For example (with half the privileges): I can't open the Even Viewer if I go via Start - Administrative Tools - Event Viewer. But I can open the Even Viewer via the server manager. You can notice this on the image below. I mean WTF??? I am going crazy, I haven't experienced anything similar in my three years of expertise. I already lost 3 days troubleshooting this. Could this be related with the cloning? Perhaps if I make fresh installs of WinSrv2008 there won't be any problems? I've had raised test domains as VMs on other occasions before, and there weren't any problems then. This is VMware Workstation 8. I've made clones before, on Workstation 7 it didn't had any problems. Anyone has any ideas? UPDATE: This is the info from the event log when I try to access via RDP: An account failed to log on. Subject: Security ID: NULL SID Account Name: - Account Domain: - Logon ID: 0x0 Logon Type: 3 Account For Which Logon Failed: Security ID: NULL SID Account Name: pat.coleman Account Domain: lab Failure Information: Failure Reason: Domain sid inconsistent.

• Why are my at jobs running immediately on OS X?

  - by Gabe

  I want to schedule events for exact times in Mac OS X. It seems like the 'at' command is the simplest way to do this. I have enabled atrun using the command: launchctl load -w /System/Library/LaunchDaemons/com.apple.atrun.plist To test at, I'm using the following one-line BASH script: echo 'foo' path/to/log.txt | at now + 2 minutes When I run the script, I get output like: job 17 at Sat May 15 12:57:00 2010 where '12:57:00' is indeed 2 minutes in the future. But the echo command executes immediately: the line 'foo' is added to log.txt right away. How can I make at work for me?

• Mapping XFCE4/xRDP sessions to users

  - by garrilla

  I have Ubuntu 13.10 with Xubuntu Desktop - XFCE4. I'm trying to use XDRP to allow MS Windows users to login to the machine with their own user. I've been a lot around the houses with this! I've find two half-way solutions, but can't get them to work as I'd like... 1) in /etc/xrdp/xrdp.ini I set the port to -1 [xrdp1] name=sesman-Xvnc lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=-1 each time any user logs on they get a new session - they can never go back to their original session 2) in /etc/xrdp/xrdp.ini I set the port to 5912 (e.g) [xrdp1] name=sesman-Xvnc lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5912 each time any user logs on they always log on to the same session irrespective of their logon details ??) I found a mid-way solution, to create a lot of sessions by adding adding additional options in the xrdp.ini e.g. [xrdp8] name=Bob's Logon lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5913 [xrdp9] name=Jill's Logon lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5914 and so on, but he problem with this is that Jill can still log into Bob's remote session ??? Is it possible to to do what I'm trying to do? Maybe I have to use different tools?

• How to find the /dev name of my USB device

  - by mustafa

  I am running Ubuntu 11 on VmWare on Windows XP. I want to format an SD card in Ubuntu. But, I can't figure out which /dev/xxx device the SD card is. I plug the card into the built-in socket of my laptop. I "safely remove" the device in Windows. Then, I "connect" the PCMCIA reader in VmWare. Now, I was supposing to see a new device like /dev/sdx. But, it doesn't appear :( How can I find what the name of my USB device's name and mount it? /var/log/message is empty. Here is the output of dmesg: [ 5268.927308] usb 2-1: new full speed USB device number 12 using uhci_hcd And, here is the last lines of /var/log/syslog: Oct 31 18:51:21 ubuntu kernel: [ 5268.927308] usb 2-1: new full speed USB device number 12 using uhci_hcd Oct 31 18:51:21 ubuntu mtp-probe: checking bus 2, device 12: "/sys/devices/pci0000:00/0000:00:11.0/0000:02:00.0/usb2/2-1" Oct 31 18:51:21 ubuntu mtp-probe: bus: 2, device: 12 was not an MTP device

• RSH between servers not working

  - by churnd

  I have two servers: one CentOS 5.8 & one Solaris 10. Both are joined to my workplace AD domain via PBIS-Open. A user will log into the linux server & run an application which issues commands over RSH to the solaris server. Some commands are also run on the linux server, so both are needed. Due to the application these servers are being used for (proprietary GE software), the software on the linux server needs to be able to issue rsh commands to the solaris server on behalf of the user (the user just runs a script & the rest is automatic). However, rsh is not working for the domain users. It does work for a local user, so I believe I have the necessary trust settings between the two servers correct. However, I can rlogin as a domain user from the linux server to the solaris server. SSH works too (how I wish I could use it). Some relevant info: via rlogin: [user@linux~]$ rlogin solaris connect to address 192.168.1.2 port 543: Connection refused Trying krb4 rlogin... connect to address 192.168.1.2 port 543: Connection refused trying normal rlogin (/usr/bin/rlogin) Sun Microsystems Inc.

• Targus USB-to-RS232 not working with Linux?

  - by Ethan Leroy

  I have the Targus PA088 USB to RS232 converter, but it seems that it does not work with linux. Its RX and TX lights are flashing, but I can't see the data in minicom/picocom. When using it with Windows and hterm, everything's fine. Any idea what could be the problem? Additional info: When I plug in the adapter, I can see the following messages in /var/log/messages.log Nov 25 01:47:31 localhost kernel: [ 831.787066] usb 2-1.1: new full speed USB device number 5 using ehci_hcd Nov 25 01:47:32 localhost kernel: [ 832.554810] mct_u232 2-1.1:1.0: MCT U232 converter detected Nov 25 01:47:32 localhost kernel: [ 832.555002] usb 2-1.1: MCT U232 converter now attached to ttyUSB0 Nov 25 01:47:32 localhost mtp-probe: checking bus 2, device 5: "/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1" Nov 25 01:47:32 localhost mtp-probe: bus: 2, device: 5 was not an MTP device

• Removing QWERTY Keyboard Layout Permanently

  - by Phoenix

  Following the instructions in this thread, I added the Dvorak layout to the Regional and Language Options control panel, set it as the default keyboard layout and removed the US (QWERTY) layout. However, even though I removed the QWERTY layout, it still appears in my language bar, and my system defaults to it in every new window. This persists after a log-out/log-in and even a system restart. How do I remove the QWERTY keyboard layout from my system permanently? Alternatively (if outright removing QWERTY is just impossible), can I get Windows to default to Dvorak instead of QWERTY for new windows?

• URL redirect to a virtual server on a VLAN

  - by zeroFiG

  I have a production site, running off 10 servers. I've been given another virtual server on the same network as these 10 servers, to use for testing purposes. This server doesn't have it's own DNS entry. Therefore I need to do a redirect to the site hosted on this virtual server for a sub-domain of the site running on the 10 other servers. So Basically I was wondering how I would configure a sub domain of my production server to point at the Virtual server for testing. I'm guessing I need to modify my site file in /etc/apache2/sites-available and add another virtual host like the following and modify the redirect match: <VirtualHost *> ServerName SUBDOMAIN.DOMAIN.com RedirectMatch 301 (.*) **IP ADDRESS** CustomLog /var/log/apache2/SUBDOMAIN.DOMAIN.com.access.log combined </VirtualHost> Do I set the redirect match to just the IP on the Virtual server, and then configure another site file in the sites-available directory, which will recption this redirect and point the browser towards the HTML root? Thanks, I hope I made myself clear.

• tracd multiple projects+nginx reverse proxy

  - by Xeross

  I am trying to setup nginx with a reverse proxy to tracd, however I only want to use 1 tracd. Now first here's my config for this domain server { listen 80; server_name bugs.XXXXXXXX.com; access_log /var/log/nginx/XXXXXXXX-bugtracker.access.log proxy; location / { rewrite ^/bugtracker/(.*)$ /$1; rewrite ^/bugtracker$ /; proxy_pass http://127.0.0.1:81/bugtracker/; proxy_redirect default; proxy_set_header Host $host; } location ~ /\.ht { deny all; } } As you can see there's the rewrite rules, because for some reason all the urls that tracd spews out are like /bugtracker/something. Now this is indeed caused by tracd just sending urls like it normally should however trac is at bugs.XXXXXXXX.com/ and not at bugs.XXXXXXXX.com/bugtracker. So how can I make tracd/trac display the (In this case) correct urls ?

• Which approach would lead to an API that is easier to use?

  - by Clem

  I'm writing a JavaScript API and for a particular case, I'm wondering which approach is the sexiest. Let's take an example: writing a VideoPlayer, I add a getCurrentTime method which gives the elapsed time since the start. The first approach simply declares getCurrentTime as follows: getCurrentTime():number where number is the native number type. This approach includes a CURRENT_TIME_CHANGED event so that API users can add callbacks to be aware of time changes. Listening to this event would look like the following: myVideoPlayer.addEventListener(CURRENT_TIME_CHANGED, function(evt){ console.log ("current time = "+evt.getDispatcher().getCurrentTime()); }); The second approach declares getCurrentTime differently: getCurrentTime():CustomNumber where CustomNumber is a custom number object, not the native one. This custom object dispatches a VALUE_CHANGED event when its value changes, so there is no need for the CURRENT_TIME_CHANGED event! Just listen to the returned object for value changes! Listening to this event would look like the following: myVideoPlayer.getCurrentTime().addEventListener(VALUE_CHANGED, function(evt){ console.log ("current time = "+evt.getDispatcher().valueOf()); }); Note that CustomNumber has a valueOf method which returns a native number that lets the returned CustomNumber object being used as a number, so: var result = myVideoPlayer.getCurrentTime()+5; will work! So in the first approach, we listen to an object for a change in its property's value. In the second one we directly listen to the property for a change on its value. There are multiple pros and cons for each approach, I just want to know which one the developers would prefer to use!

• Issue with percona-xtrabackup-2.0.0 hotbackup on MyIsam tables

  I am trying to implement hot backup for MyIsam tables with "percona-xtrabackup-2.0.0" and getting the following error? As the all tables are MyIsam I doubt am I using the correct package ?

• The session setup from the computer <computerName> failed to authenticate.

  - by TheCodeMonk

  Every once in a while, I get a client PC that won't be able to log into the domain. This morning it was telling us that the trust relationship between the pc and the domain failed. I checked the event logs on the primary domain controller and I see this for 2 PCs (the one that had the problem and one that can log in today). The session setup from the computer failed to authenticate. The name(s) of the account(s) referenced in the security database is . The following error occurred: Access is denied. I know how to fix this, by rejoining the PC to the domain... But why does this happen and how can I prevent it so I don't have to keep rejoining PCs to the domain?

• Why aren't Heroku syslog drains logging to rsyslogd?

  - by Benjamin Oakes

  I'm having a problem using syslog drains as described in https://devcenter.heroku.com/articles/logging. To summarize, I have an Ubuntu 10.04 instance on EC2 that is running rsyslogd. I've also set up the security groups as they describe, and added a syslog drain using a command like heroku drains:add syslog://host1.example.com:514. I can send messages from the Heroku console to my rsyslogd instance via nc. I see them appear in the log file, so I know there isn't a firewall/security group issue.  However, Heroku does not seem to be forwarding log messages to the server that heroku drains lists. I would expect to see HTTP requests, Rails messages, etc. Is there something else I can try to figure this out? I'm new to rsyslogd, so I could easily be missing something.

• mpd conflicting with other applications -- taking control of pulse?

  - by Jamie Schembri

  Simple explanation If mpd is playing and sound attempts to play through another application, x, sound from x will not be output. If sound from another application, x, is playing and mpd then attempts to play, no sound will be output from mpd whilst sound from x continues to play. Details I first noticed this problem with Flash, and this continues to be the most common scenario. I posted a question about this before realising it was not strictly Flash-related, but instead is something to do with mpd. My biggest frustration comes from trying to get mpd working again, as I can't seem to pin down any method. Sometimes pulseaudio -k seems to help, other times sudo /etc/init.d/mpd restart, others killing Chromium (due to Flash) with SIGTERM. Most of the time it's a combination of the above. I think this might be because I run mpd as another user and use pulseaudio. It is not run as root or current user. Also, mpd is compiled with pulse support. I have tried numerous things, however I honestly couldn't recite what, as it has been some time since. I'd rather not go poking around without some direction, but I'd be really happy to fix this problem once and for all. mpd.conf Simplified by removing comments/blank lines. music_directory "/var/lib/mpd/music" playlist_directory "/var/lib/mpd/playlists" db_file "/var/lib/mpd/tag_cache" log_file "/var/log/mpd/mpd.log" pid_file "/var/run/mpd/pid" state_file "/var/lib/mpd/state" user "mpd" bind_to_address "wilson" input { plugin "curl" } audio_output { type "pulse" name "My Pulse Output" } filesystem_charset "UTF-8" id3v1_encoding "UTF-8" Question For the sake of keeping this a question: does anyone know what is causing this, or how to fix it?
