• How to verify PostgreSQL 9 has installed correctly on a CentOS server?

  - by A4J

  I'm trying to install the PG (postgres) gem on a CentoOS server, but it keeps saying Postgres is too old, even though I have upgraded it to 9.1.3 (as per the instructions here http://www.davidghedini.com/pg/entry/install_postgresql_9_on_centos). I am using CentOS 5.8 (and Ruby 1.9.3) Here is the error message: Building native extensions. This could take a while...

• MAC addresses on dual-NIC mainboards

  - by Tom O'Connor

  Here's a weird problem. We've got a number of devices with dual-NIC mainboards. Some are Realtek NICs, which suck. Some are Intel e1000s, which don't. I've just noticed on 2 machines, one is an Intel NIC, one is a Realtek, that when I put the MAC address of one machine into the dhcpd.conf file on our DHCP server to get it to PXE boot the machine into a rebuild environment, initially everything is fine. The server gets a DHCP allocation, and PXE boots into the Ubuntu preseed enviroment. On one or two machines, it gets as far as Ubuntu's DHCP network configuration, and fails. If i pull up a busybox shell (on tty2 on the installing machine), and run ip link, I can see that the UP flag is set on the other NIC. Here's some stuff. host xeon16-ghz240-gb48-node1 { hardware ethernet BC:AE:C5:07:1F:18; filename "pxelinux.0"; next-server 192.168.123.80; } That's what's in dhcpd.conf This is what ip link on the evil machine looks like. Only one NIC is actually connected (deliberately). As you can see, the NIC that's in the dhcpd config, is not marked as UP, and the link that is UP, isn't the one in DHCP. So far I've seen this on two brands of dual-NIC configuration. Does anyone know 1) what's causing it, and b) What we can do about it?

• memcached append() php ubuntu - bad protocol

  - by awongh

  I am running ubuntu gutsy(7.1) , php5 and I am trying to get memcached running locally. I installed everything as per the docs: memcached daemon, php PECL extension, libevent, etc. But now I can only run half of the example script for memcached append(): <?php $m = new Memcached(); $m->addServer('localhost', 11211); $m->setOption(Memcached::OPT_COMPRESSION, false); $m->set('foo', 'abc'); $m->append('foo', 'def'); var_dump($m->get('foo')); ?> the script terminates @ append() with an RES_BAD_PROTOCOL error message. It still runs the get(). I don't know why memcached would otherwise be working fine (connect, set, get - with the correct value of 'abc') and not work for append. it also doesnt work with prepend. I believe I have the setup correct, but I am not sure. Maybe there are compatibility problems between the versions of the dependecies? thanks much

• Setting Ubuntu Global PATH for Ruby Enterprise Edition

  - by Wally Glutton

  Context: I recently installed Ruby Enterprise Edition (REE) on an Ubuntu 8.04 server. I would like for this new version of Ruby to globally supersede (for all users, crontabs, etc) the older version in /usr/local/bin. Attempted Solution #1: The REE documentation recommends placing the REE bin folder at the beginning of the global PATH in /etc/environment. I altered the PATH line in this file to read: PATH="/opt/ruby_ee/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" This did affect my PATH at all. Attempted Solution #2: Next I followed these instructions and updated the PATH setting in the /etc/login.defs and /etc/crontab files. (I did not change /etc/sudoers.) This didn't affect my PATH either, even after logging out and rebooting the server. Other information: I seem to be having the same problem described here. I'm testing using the command: echo $PATH My shell is bash. My .bashrc doesn't not alter my PATH. I'm ssh'ed into the system for all testing. /opt/ruby_ee/ is a sym-link to /opt/ruby-enterprise-1.8.7-2011.03/

• Tomcat 6 Windows Server 64 Redirect Connector Fails

  - by Rafe

  So is there some problem with running the Tomcat connectors under a 64 bit windows OS? Here's my configuration: Windows Server 2003 64 bit Intel Xeon Tomcat 6.0.26 JVM 1.6.0 (64bit) ISAPI Redirect Connector 1.2.30.0 (64 bit) Calling the IP address of the site with :8080 brings up the tomcat page so I know that's running and the examples all work so its obviously not having a problem with the JVM. Calling the site ip on port 80 however gives me error 324 - looking at the application log on windows shows "Could not load all ISAPI filters for site/service. Therefore startup aborted". The ISAPI filter page under the web site properties shows the status of this filter to be down with a red arrow. The ISAPI filter name is jakarta and there is a corresponding virtual directory set up in the root of the site pointing to the same directory as the filter. The jakarta web service extension is also pointing to the required dll (c:\program files\apache software foundation\jakarta isapi redirector\bin\isapi_redirect.dll). Incidentally, this same problem occurs when trying to use Tomcat 5.5. I've also tried swapping out various redirect versions. It's really odd because I got it to work once with a version of the redirector that came with Plesk but I've since uninstalled everything to do with plesk and even trying to use the plesk-compiled dll doesn't work now. I am pulling my hair out on this, any ideas?

• script to run sox to combine multiple mono tracks to stereo

  - by Ze'ev

  I have a folder full of .wav audio files. Some are stereo, most are mono splits. The mono split pairs are all named foo bar track.L.wav and foo bar track.R.wav I can use the command line tool sox to combine a mono pair into 1 stereo track like this: sox -M track1.L.wav track1.R.wav track1.Stereo.wav where the first 2 files are the mono pairs, and the third is the output stereo file. This is great, but I'd like to have a script that will automatically find all the mono pairs and combine them into stereo files. I.e., I need it to find all files which have the same name except for the .L. and .R. before the extension, and run sox on them, outputting to a new file with the same name without the L/R suffix. For example, if my folder contains these files: track1.L.wav track2.L.wav track3.L.wav track4.L.wav track1.R.wav track2.R.wav track3.R.wav track4.R.wav track6.wav track7.wav I need to run these commands: sox -M track1.L.wav track1.R.wav track1.Stereo.wav sox -M track2.L.wav track2.R.wav track2.Stereo.wav sox -M track3.L.wav track3.R.wav track3.Stereo.wav sox -M track4.L.wav track4.R.wav track4.Stereo.wav Here's where I am so far: for file in ./*.L.wav; do file2=`echo $file | sed 's_\(.*\).L.wav_\1.R.wav_'`; out=`echo $file | sed 's_\(.*\).L.wav_\1.STEREO.wav_'`; echo $file - $file2 - $out; done That works, but when I replace the echo line with sox -M $file $file2 $out; it doesn't work; spaces in the filenames cause it to fail.

• Linux Kernel Packet Forwarding Performance

  - by Bob Somers

  I've been using a Linux box as a router for some time now. Nothing too fancy, just enabling forwarding in the kernel, turning on masquerading, and setting up iptables to poke a few holes in the firewall. Recently a friend of mine pointed out a performance problem. Single TCP connections seem to experience very poor performance. You have to open multiple parallel TCP connections to get decent speed. For example, I have a 10 Mbit internet connection. When I download a file from a known-fast source using something like the DownThemAll! extension for Firefox (which opens multiple parallel TCP connections) I can get it to max out my downstream bandwidth at around 1 MB/s. However, when I download the same file using the built-in download manager in Firefox (uses only a single TCP connection) it starts fast and the speed tanks until it tops out around 100 KB/s to 350 KB/s. I've checked the internal network and it doesn't seem to have any problems. Everything goes through a 100 Mbit switch. I've also run iperf both internally (from the router to my desktop) and externally (from my desktop to a Linux box I own out on the net) and haven't seen any problems. It tops out around 1 MB/s like it should. Speedtest.net also reports 10 Mbits speeds. The load on the Linux machine is around 0.00, 0.00, 0.00 all the time, and it's got plenty of free RAM. It's an older laptop with a Pentium M 1.6 GHz processor and 1 GB of RAM. The internal network is connected to the built in Intel NIC and the cable modem is connected to a Netgear FA511 32-bit PCMCIA network card. I think the problem is with the packet forwarding in the router, but I honestly am not sure where the problem could be. Is there anything that would substantially slow down a single TCP stream?

• Making OpenSSL work on PHP Windows 2008 server with FastCGI

  - by KacieHouser

  I have been researching all day.

• How can I get Thunderbird to automatically move messages?

  - by David Heffernan

  I have Thunderbird 15. I'd like to automatically move messages from one folder to another. My mail account is an IMAP account. My Blackberry is also connected to the account and when it sends mail, it places a copy on the IMAP server in a folder named Sent Items. I'd like those messages to be moved to my Inbox automatically. By default message filters are only applied automatically to the Inbox. There is an extension to do this, Filter Subfolders, but it's only for TB3. What I have tried so far is: Use the FiltaQuilla add-on to be able to filter messages for folder name. Set the string property mail.server.default.applyIncomingFilters to true. As recommended here: http://blog.mozilla.org/bcrowder/ But I can't get these filters to run automatically. I have a suspicion that filters only run automatically for incoming mail. And these are sent items. Perhaps that's it. I just don't know. On the other hand, if I run the filters manually on that folder, it does indeed move the mail. Or perhaps the issue is that these messages are saved into the Sent Items folder marked as read. Is it possible that filters are only automatically applied to unread items? If I could install an add-in that automatically ran the message filter on my folder, that would do it. Anyway, I'm at a loss now. Any suggestions are welcome. I'm not at all wedded to using filters. I just want to find a way to get these messages moved without human interaction!

• Wrong CSS mime type with Roundcube 0.5 beta and nginx

  - by Julien Vehent

  I'm running into a CSS problem. This is a setup based on Debian Squeeze (nginx/0.7.67, php5/cgi) on which I installed the latest Roundcube 0.5 beta. PHP is properly processed, login works fine but the CSS files are not loaded and Firefox is throwing the following errors: Error: The stylesheet https://webmail.example.net:10443/roundcube/skins/default/common.css?s=1290600165 was not loaded because its MIME type, "text/html", is not "text/css". Source File: https://webmail.example.net:10443/roundcube/?_task=login Line: 0 Error: The stylesheet https://webmail.example.net:10443/roundcube/skins/default/mail.css?s=1290156319 was not loaded because its MIME type, "text/html", is not "text/css". Source File: https://webmail.example.net:10443/roundcube/?_task=login Line: 0 As far as I understand, nginx doesn't see the .css extension (because ofthe ?s= argument) and thus set the mime type with the default value, being text/html. Should I fix this in nginx (and how ?) or is it roundcube's related ? Edit: It seems that it's nginx related. The content-type isn't set for any other type than text/html. I had to include manually the following declarations to force CSS and JS content-types. That's ugly, and I never had the problem before... any idea ? location ~ \.css { add_header Content-Type text/css; } location ~ \.js { add_header Content-Type application/x-javascript; }

• Apache2 refuses to process php files - "Snow Leopard" OSX 10.6.4

  - by w-01

  I have a macbook pro i5. my understanding is that by default it should be able to serve php5. i have uncommented the relevant line in /etc/apache2/httpd.conf LoadModule php5_module libexec/apache2/libphp5.so I have restarted apache with sudo apachectl -k restart and when i try to access a file with a php extension, Apache prompts me to download the file. i.e. instead of processing the php and sending me html, it thinks i want to download the file.... when i look in apache error log i see this [Fri Nov 12 10:16:14 2010] [notice] Apache/2.2.14 (Unix) PHP/5.3.2 mod_ssl/2.2.14 OpenSSL/0.9.8l DAV/2 mod_wsgi/3.2 Python/2.6.1 configured -- resuming normal operations so it looks like php5 is loading properly. I'd like to know either: How do i fix this? or How do I reinstall apache2 so that it's like i just installed the os? thanks in advance update @Zayne - the end of my httpd.conf has Include /private/etc/apache2/other/*.conf and i have a file /etc/apache2/other/php.conf with the contents <IfModule php5_module> AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps <IfModule dir_module> DirectoryIndex index.html index.php </IfModule> </IfModule> @Zayne I've already copied php.ini.default to php.ini in the same folder. when i run sudo apachectl configtest i get /usr/sbin/apachectl: line 82: ulimit: open files: cannot modify limit: Invalid argument httpd: Could not reliably determine the server's fully qualified domain name, using ::1 for ServerName Syntax OK furthermore i decided to try apachectl -M which shows all loaded modules Most importantly in the list of loaded modules i got Loaded Modules: php5_module (shared) Since the module is being loaded, it seems like the issue has more to do with making apache use php engine to process the php files.... so something wrong with the ifmodule directive?

• Menu tab completion for recent history in zsh

  - by dat5h

  I am interested in a potential zle widget for zsh. Is there a way to build a widget that mimics the kill-completion selectable menu? Essentially I want to be able to press , tab in vi-command-mode, or maybe !-tab-completion at the shell and get a list of recent history (or related history compared what is already entered at the commandline) that allows me to scroll through it and possibly select a relevant function to call or compare similar calls. Looking through the manual I stumbled onto a similar widget that I have mapped like so: # tab completion history menu (vicmd) autoload -z history-beginning-search-menu zle -N history-beginning-search-menu-space-end history-beginning-search-menu bindkey -M vicmd "\t" history-beginning-search-menu-space-end # emacs binding could be "\e\t"? (I wouldn't know) Therefore, if I enter vicmd and hit tab when I enter something like "grep", then I get a list of all grep calls in history. It also asks me for the list-number and it will perform the numbered item in history. If I enter a space and then try this, it lists ALL of my history history. This is fairly close to what I want, but there are some problems. For example, 1) it prints the entire list of relevant history and does not check the number of lines of the screen so it could easily blow up the space on the terminal; 2) when I type in numbers for selecting an item in history it does not show me the numbers I type, so I may make a mistake and have to start over again; 3) I would love to be able to hook in appearance tweaks. I was wondering if there exists more updated version of this widget or if there is any way to look at the source for kill-completion or history-beginning-search-menu to see if I could think of a way to do it.

• Why from a virtualized Ubuntu system I can't discover the ip address of my router?

  - by AndreaNobili

  I am not into computer network and I have the following problem finding my router IP address. I have a Windows 8 PC on on which it is installed VmWare Workstation that virtualizes Linux Ubuntu. The network adapter settings of this Virtual Machine is setted as NAT. Now my problem is that if in the Windows 8 DOS shell I perform the ifconfig statment I obtain C:\Users\Andrea>ipconfig Configurazione IP di Windows Scheda Ethernet tap0: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: techub.lan Scheda Ethernet Connessione di rete Bluetooth: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda LAN wireless Connessione alla rete locale (LAN)* 11: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda LAN wireless Wi-Fi: Suffisso DNS specifico per connessione: DSL2750B Indirizzo IPv6 locale rispetto al collegamento . : fe80::89ff:6d12:49cf:4354%13 Indirizzo IPv4. . . . . . . . . . . . : 192.168.1.3 Subnet mask . . . . . . . . . . . . . : 255.255.255.0 Gateway predefinito . . . . . . . . . : 192.168.1.1 Scheda Ethernet Ethernet: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda Ethernet VMware Network Adapter VMnet1: Suffisso DNS specifico per connessione: Indirizzo IPv6 locale rispetto al collegamento . : fe80::edb3:8352:f954:2b0c%23 Indirizzo IPv4. . . . . . . . . . . . : 192.168.129.1 Subnet mask . . . . . . . . . . . . . : 255.255.255.0 Gateway predefinito . . . . . . . . . : Scheda Ethernet VMware Network Adapter VMnet8: Suffisso DNS specifico per connessione: Indirizzo IPv6 locale rispetto al collegamento . : fe80::d00b:8c6e:98b:f1ec%24 Indirizzo IPv4. . . . . . . . . . . . : 192.168.15.1 Subnet mask . . . . . . . . . . . . . : 255.255.255.0 Gateway predefinito . . . . . . . . . : Scheda Tunnel Teredo Tunneling Pseudo-Interface: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda Tunnel isatap.techub.lan: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: techub.lan Scheda Tunnel isatap.{5B95051D-79AB-4147-92CF-3A2E16698432}: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda Tunnel isatap.{340A5FAD-1597-402E-B658-29C37E8F7BC2}: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda Tunnel isatap.DSL2750B: Suffisso DNS specifico per connessione: DSL2750B Indirizzo IPv6 locale rispetto al collegamento . : fe80::5efe:192.168.1.3%26 Gateway predefinito . . . . . . . . . : So, looking at the previous output it appear clear that the default gateway (my router) is: 192.168.1.1, infact if I open it into a browser it apear to me the login mask to enter in the router settings.... Ok, if now I open the virtualized Ubuntu shell and perform the route command I obtain this output: andrea@andrea-virtual-machine:~$ route Tabella di routing IP del kernel Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.15.2 0.0.0.0 UG 0 0 0 eth0 link-local * 255.255.0.0 U 1000 0 0 eth0 192.168.15.0 * 255.255.255.0 U 1 0 0 eth0 So, here it say to me that the default gateway is 192.168.15.2 (that is not my router ip address), why? My idea is that it could depend by the NAT. Because my Windows system is connected using the wireless but in the virtualized Ubuntu I see that I am connected to a "wired network". So I think that the NAT virtualize a network adapter (or something like this) and that 192.168.15.2 could be the ip address of this network adapter... But it seems strange to me because, as you can see in the previous ipconfig output the VmWare network adapter addresses are: 192.168.129.1 and 192.168.15.1. So I have also 2 others doubts: 1) What device represents the 192.168.15.2 ip address that the virtualized Ubuntu see as Default gateway but that is not my router? 2) What exactly do the two VmWare network adapter that I have configured into my Windows 8 system? There is a way to discover my router ip from the virtualized Ubuntu system ? Tnx Andrea

• How to run Android-x86 project's ISO in VirtualBox with ethernet?

  - by Shiki

  I managed to find a way just days ago, but I had to leave my other PC and now I have no clue how to get it working again. Basically you have to get the image, then install it in a VirtualBox guest. Now the problem is ... when you launch your VM, there is no internet connection. No with NAT or Bridged. Tried all the network cards too. Since internet connection is crucial for Android development, I have to get this thing working. (As I said, I managed to fix it once.) I'm using: - The 4.0 RC1 images from Android-x86 - VirtualBox - Eclipse 4.2 Juno with the latest Android ADT - Android SDK v18 - upgraded to 19 via the Package manager. Now I seen a lot of different builds on the net, about different Android builds for VirtualBox. I have checked Buildroid for example, but there is no network connection. I have imported the virtual machine just as the howto said. The extension package is also installed and it's up to date.

• PHP/Linux File Permissions

  - by user1733435

  May I ask a question about file permission. I set up Ubuntu server where Apache got running. I have simple php upload form and able to upload file to /var/www/site/uploads as follows. sandbox@sandbox-virtual-machine:/var/www/site/uploads$ ll total 1736 drwxrwxrwx 2 www-data www-data 4096 Oct 18 02:53 ./ drwxrwxrwx 3 sandbox sandbox 4096 Oct 18 00:42 ../ -rw-r--r-- 1 www-data www-data 145998 Oct 18 02:53 3d wallpaper pic.jpg -rw-r--r-- 1 www-data www-data 166947 Oct 18 02:53 3D Wallpapers 9.jpg -rw-r--r-- 1 www-data www-data 1451489 Oct 18 02:53 6453_3d_landscape_hd_wallpapers_green.jpg Is there anyway to upload files and they show up as -rw-r--r-- 1 sandbox sandbox 145998 Oct 18 02:53 3d wallpaper pic.jpg -rw-r--r-- 1 sandbox sandbox 166947 Oct 18 02:53 3D Wallpapers 9.jpg -rw-r--r-- 1 sandbox sandbox 1451489 Oct 18 02:53 6453_3d_landscape_hd_wallpapers_green.jpg so that I could straight away feed them to waiting/running shell script. Right now waiting script(move,checksums,rename,resize,etc) unable to do anything to uploaded files with attributes of www-data. If I just do as local account, such as sandbox@sandbox-virtual-machine:/var/www/site/uploads$touch testfile then the script is able to run as I would like to. Any suggestion would be grateful,thanks in advance as well. Thanks for everyone giving help to me,that I was able to progress. Now I am close to getting solved and append the output sandbox@sandbox-virtual-machine:/var/www/site/uploads$ ll total 388 drwxrwxrwx 2 www-data www-data 4096 Oct 18 04:22 ./ drwxrwxrwx 3 sandbox sandbox 4096 Oct 18 04:17 ../ -rw-r--r-- 1 sandbox sandbox 166947 Oct 18 04:21 3D Wallpapers 9.jpg -rw-r--r-- 1 sandbox sandbox 219808 Oct 18 04:20 adafruit_pi.png -rw-rw-r-- 1 sandbox sandbox 0 Oct 18 04:22 test How may I set permission to uploaded files like 'test' only w difference in middle group. Such as adafruit_pi.png Vs test. Which statement shall I insert to php code,please?

• Gluster bricks are offline and errors in logs

  - by Roman Newaza

  I have substituted all the IP addresses with hostnames and renamed configs (IP to hostname) in /var/lib/glusterd by my shell script. After that I restarted Gluster Daemon and the volume. Then I checked if all the peers are connected: root@GlusterNode1a:~# gluster peer status Number of Peers: 3 Hostname: gluster-1b Uuid: 47f469e2-907a-4518-b6a4-f44878761fd2 State: Peer in Cluster (Connected) Hostname: gluster-2b Uuid: dc3a3ff7-9e30-44ac-9d15-00f9dab4d8b9 State: Peer in Cluster (Connected) Hostname: gluster-2a Uuid: 72405811-15a0-456b-86bb-1589058ff89b State: Peer in Cluster (Connected) I could see mounted volumes size change on all the nodes when I execute df command, so new data is coming. But recently I noticed error messages in app log: copy(/storage/152627/dat): failed to open stream: Structure needs cleaning readfile(/storage/1438227/dat): failed to open stream: Input/output error unlink(/storage/189457/23/dat): No such file or directory Finally, I have found out some bricks are offline: root@GlusterNode1a:~# gluster volume status Status of volume: storage Gluster process Port Online Pid ------------------------------------------------------------------------------ Brick gluster-1a:/storage/1a 24009 Y 1326 Brick gluster-1b:/storage/1b 24009 N N/A Brick gluster-2a:/storage/2a 24009 N N/A Brick gluster-2b:/storage/2b 24009 N N/A Brick gluster-1a:/storage/3a 24011 Y 1332 Brick gluster-1b:/storage/3b 24011 N N/A Brick gluster-2a:/storage/4a 24011 N N/A Brick gluster-2b:/storage/4b 24011 N N/A NFS Server on localhost 38467 Y 24670 Self-heal Daemon on localhost N/A Y 24676 NFS Server on gluster-2b 38467 Y 4339 Self-heal Daemon on gluster-2b N/A Y 4345 NFS Server on gluster-2a 38467 Y 1392 Self-heal Daemon on gluster-2a N/A Y 1402 NFS Server on gluster-1b 38467 Y 2435 Self-heal Daemon on gluster-1b N/A Y 2441 What can I do about that?

• Can't successfully run Sharepoint Foundation 2010 first time configuration

  - by Robert Koritnik

  I'm trying to run the non-GUI version of configuration wizard using power shell because I would like to set config and admin database names. GUI wizard doesn't give you all possible options for configuration (but even though it doesn't do it either). I run this command: New-SPConfigurationDatabase -DatabaseName "Sharepoint2010Config" -DatabaseServer "developer.mydomain.pri" -AdministrationContentDatabaseName "Sharepoint2010Admin" -DatabaseCredentials (Get-Credential) -Passphrase (ConvertTo-SecureString "%h4r3p0int" -AsPlainText -Force) Of course all these are in the same line. I've broken them down into separate lines to make it easier to read. When I run this command I get this error: New-SPConfigurationDatabase : Cannot connect to database master at SQL server a t developer.mydomain.pri. The database might not exist, or the current user does not have permission to connect to it. At line:1 char:28 + New-SPConfigurationDatabase <<<< -DatabaseName "Sharepoint2010Config" -Datab aseServer "developer.mydomain.pri" -AdministrationContentDatabaseName "Sharepoint 2010Admin" -DatabaseCredentials (Get-Credential) -Passphrase (ConvertTo-SecureS tring "%h4r3p0int" -AsPlainText -Force) + CategoryInfo : InvalidData: (Microsoft.Share...urationDatabase: SPCmdletNewSPConfigurationDatabase) [New-SPConfigurationDatabase], SPExcep tion + FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletNewSPCon figurationDatabase I created two domain accounts and haven't added them to any group: SPF_DATABASE - database account SPF_ADMIN - farm account I'm running powershell console as domain administrator.

• TomTom GO & Ubuntu Linux: impersonating a GPRS phone with dund

  - by Broam

  Background: I've called TomTom support, and they don't support Linux. I can get my GO 730 to mount Mass Storage, and I found a shell script that will allow me to install maps (haven't tried it; will update when I do.). As of note: USB 2.0 only. 1.1 ports will not work. However--I still can't update the TomTom or take advantage of any traffic services. The GO will connect to a mobile phone, but I don't have one that supports tethering. However, I've found a site that claims to know a way to get a Linux Machine to impersonate a phone advertising GPRS services and it apparently works in Fedora as old as FC4. I'm having some serious trouble getting this to work on Ubuntu 9.10 Karmic, mainly because I think some of the built-in bluetooth stuff is getting in the way. Changing the class bits in main.conf (hcid.conf does not exist) doesn't crash..., and dund starts and listens, but the TomTom device never seems to want to connect to my machine. I haven't played around much with sdcptool (I think that's the name, not in front of a Linux machine right now) but maybe I have to advertise the DUN profile...I'm not very sure. My Question: I have no way to diagnose the problems. What are some diagnostic tools I can use to help dig down and figure out what's going on? Update: apparently dund is a legacy tool that's going away. What replaces it?

• ZFS - destroying deduplicated zvol or data set stalls the server. How to recover?

  - by ewwhite

  I'm using Nexentastor on a secondary storage server running on an HP ProLiant DL180 G6 with 12 Midline (7200 RPM) SAS drives. The system has an E5620 CPU and 8GB RAM. There is no ZIL or L2ARC device. Last week, I created a 750GB sparse zvol with dedup and compression enabled to share via iSCSI to a VMWare ESX host. I then created a Windows 2008 file server image and copied ~300GB of user data to the VM. Once happy with the system, I moved the virtual machine to an NFS store on the same pool. Once up and running with my VMs on the NFS datastore, I decided to remove the original 750GB zvol. Doing so stalled the system. Access to the Nexenta web interface and NMC halted. I was eventually able to get to a raw shell. Most OS operations were fine, but the system was hanging on the zfs destroy -r vol1/filesystem command. Ugly. I found the following two OpenSolaris bugzilla entries and now understand that the machine will be bricked for an unknown period of time. It's been 14 hours, so I need a plan to be able to regain access to the server. http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6924390 and http://bugs.opensolaris.org/bugdatabase/view_bug.do;jsessionid=593704962bcbe0743d82aa339988?bug_id=6924824 In the future, I'll probably take the advice given in one of the buzilla workarounds: Workaround Do not use dedupe, and do not attempt to destroy zvols that had dedupe enabled. Update: I had to force the system to power off. Upon reboot, the system stalls at Importing zfs filesystems. It's been that way for 2 hours now.

• Write access from a Windows client via a ZFS SMB, to a file created on the host in OpenIndiana

  - by Gerald Kaszuba

  I've got an OpenIndiana server running ZFS that is shared using a nobody user and group. I don't fully understand Solaris ACL permissions, but I do know Linux style permissions. The client is Windows 8 and the server is OpenIndiana is oi_148. I'm failing to work out how to make write permission work correctly for the Windows client. It is able to make new files, but can not modify files created by the shell in OpenIndiana. When a file ("local file") is created locally as the user nobody in bash, and another file ("smb file") created remotely via SMB (as nobody also), they are quite different in permissions: # ls -V -rw-r--r-- 1 nobody nobody 0 Dec 2 12:24 local file owner@:rw-p--aARWcCos:-------:allow group@:r-----a-R-c--s:-------:allow everyone@:r-----a-R-c--s:-------:allow -rwx------+ 1 nobody nobody 0 Dec 2 12:24 smb file user:nobody:rwxpdDaARWcCos:-------:allow group:2147483648:rwxpdDaARWcCos:-------:allow In bash, I'm able to write to smb file, but vice versa, the Windows client is not able to write to local file. This is confusing to me because it appears that it should allow the SMB client to write to local file, because nobody is the owner and it has a w in the ACL. The sharesmb setting is is fairly boring, although I'm hoping there can something to set in here similar to a umask: sharesmb name=shared,guestok=true How can I make these two work together and have a symmetrical permission system, where both SMB and the local user produce the same permissions? Is there some sort of ACL that can set at the root of the file system to allow all files to be created in a similar manner?

• Whitelist IP from google-authenticator in sshd pam

  - by spudwaffle

  My Ubuntu 12.04 server uses the google-authenticator pam module to provide two step authentication for ssh. I need to make it so that a certain IP does not need to type the verification code. The /etc/pam.d/sshd file is below: # PAM configuration for the Secure Shell service # Read environment variables from /etc/environment and # /etc/security/pam_env.conf. auth required pam_env.so # [1] # In Debian 4.0 (etch), locale-related environment variables were moved to # /etc/default/locale, so read that as well. auth required pam_env.so envfile=/etc/default/locale # Standard Un*x authentication. @include common-auth # Disallow non-root logins when /etc/nologin exists. account required pam_nologin.so # Uncomment and edit /etc/security/access.conf if you need to set complex # access limits that are hard to express in sshd_config. # account required pam_access.so # Standard Un*x authorization. @include common-account # Standard Un*x session setup and teardown. @include common-session # Print the message of the day upon successful login. session optional pam_motd.so # [1] # Print the status of the user's mailbox upon successful login. session optional pam_mail.so standard noenv # [1] # Set up user limits from /etc/security/limits.conf. session required pam_limits.so # Set up SELinux capabilities (need modified pam) # session required pam_selinux.so multiple # Standard Un*x password updating. @include common-password auth required pam_google_authenticator.so I've already tried adding a auth sufficient pam_exec.so /etc/pam.d/ip.sh line above the google-authenticator line, but I can't understand how to check an IP adress in the bash script.

• sequential SSH command execution not working in Ubuntu/Bash

  - by kumar

  My requirement is I will have a set of commands that needs to be executed in a text file. My Shell script has to read each command, execute and store the results in a separate file. Here is the snippet which does the above requirement. while read command do echo 'Command :' $command >> "$OUTPUT_FILE" redirect_pos=`expr index "$command" '>>'` if [ `expr index "$command" '>>'` != 0 ];then redirect_fn "$redirect_pos" "$command"; else $command state=$? if [ $state != 0 ];then echo "command failed." >> "$OUTPUT_FILE" else echo "executed successfully." >> "$OUTPUT_FILE" fi fi echo >> "$OUTPUT_FILE" done < "$INPUT_FILE" Sample Commands.txt will be like this ... tar -rvf /var/tmp/logs.tar -C /var/tmp/ Commands_log.txt gzip /var/tmp/logs.tar rm -f /var/tmp/list.txt This is working fine for commands which needs to be executed in local machine. But When I am trying to execute the following ssh commands only the 1st command getting executed. Here are the some of the ssh commands added in my text file. ssh uname@hostname1 tar -rvf /var/tmp/logs.tar -C /var/tmp/ Commands_log.txt ssh uname@hostname2 gzip /var/tmp/logs.tar ssh .. etc When I am executing this in cli it is working fine. Could anybody help me in this?

• Configuring vsftpd with nginx on Ubuntu 12.04 LTS

  - by arby

  I've attempted to configure a nginx / vsftpd server on Ubuntu 12.04 LTS (via amazon ec2) a couple times now, but I seem to keep making a mistake along the way. Currently, when I try to connect to my ftp server it takes a minute or so before it connects. Then when I issue a command, they all timeout with an operation failed error. Aside from these issues, I'm not completely confident with the file ownership & permissions or the configuration / settings. So, I think it's best if I just re-install and re-configure correctly. I believe the nginx installation comes with a default user of www-data:www-data and web root directory ownership by root:root. Vsftpd, however, needs to have a user created with the same group as the nginx user (www-data), and the same home directory as the nginx server (/usr/share/nginx/www), with g+w chmod permissions granted on that directory. The vsftpd.conf file should disable anonymous logins and enable local logins, file writing, and chroot local users. In my previous config, I had /bin/false set for the ftp user's shell and pam_shells.so disabled. I also had local_umask set to 0027. So, starting with a fresh ec2 instance, I've got: sudo apt-get install vsftpd sudo apt-get install nginx For the firewall I issued the command (not sure if necessary): sudo ufw allow ftp Which commands / config is recommended from here? I only need 1 ftp user that I can use to login with my ftp client to modify the single nginx web domain, which will need php & sql for WordPress.
