  • Postfix tutorial inconsistency

    - by Desmond Hume
    I'm following this tutorial to setup a Postfix/Dovecot mail server with Postfix Admin as a web front end. As regards directory structure for virtual mail users, the author of the tutorial writes: Virtual mail users are those that do not exist as Unix system users. They thus don't use the standard Unix methods of authentication or mail delivery and don't have home directories. That is how we are managing things here: mail users are defined in the database created by Postfix Admin rather than existing as system users. Mail will be kept in subfolders per domain and account under /var/vmail - e.g. [email protected] will have a mail directory of /var/vmail/example.com/me. But when he gives instructions about configuring Postfix Admin, he suggests this to be contained by Postfix Admin's config.inc.php: // Mailboxes // If you want to store the mailboxes per domain set this to 'YES'. // Examples: // YES: /usr/local/virtual/domain.tld/[email protected] // NO: /usr/local/virtual/[email protected] $CONF['domain_path'] = 'NO'; Is there an inconsistency?

  • apache2 installation conflicts with previous lampp content

    - by Fruit
    hej, i downloaded xampp-linux-1.7.3a.tar.gz and installed it manually, not with aptitude. That was a mistake as proved later, due to some configurational issues i decided to remove it and install it via aptitude install apache2. Now the previous lampp conflicts with the new apache2, i get this error message. Starting web server apache2 apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down how can delete the existing lampp files entirely or how can i configure apache2 to work as intended ? any help will be appreciated

  • Why are the analoge stereo input and output of my M-Audio 24/96 soundcard not available to me in Ubu

    - by user37968
    I have installed Lucid on an old Mac PowerPC G4 desktop with a M-Audio Audiophile 24/96 soundcard. The only inputs and outputs I can select in the audio preferences are digital ones for the digital input and output. "lspci -v" shows the card as so: 0001:10:13.0 Multimedia audio controller: VIA Technologies Inc. ICE1712 [Envy24] PCI Multi-Channel I/O Controller (rev 02) Subsystem: VIA Technologies Inc. Device d634 Flags: bus master, medium devsel, latency 16, IRQ 53 I/O ports at 0440 [size=32] I/O ports at 04b0 [size=16] I/O ports at 04a0 [size=16] I/O ports at 0400 [size=64] Capabilities: <access denied> Kernel driver in use: ICE1712 Kernel modules: snd-ice1712 "cat /proc/asound/cards" as so: 0 [Tumbler ]: PMac Tumbler - PowerMac Tumbler PowerMac Tumbler (Dev 21) Sub-frame 0 1 [M2496 ]: ICE1712 - M Audio Audiophile 24/96 M Audio Audiophile 24/96 at 0x440, irq 53 "aplay -L" shows these as listed: pulse Playback/recording through the PulseAudio sound server front:CARD=Tumbler,DEV=0 PowerMac Tumbler, PowerMac Tumbler Front speakers front:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi Front speakers surround40:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi 4.0 Surround output to Front and Rear speakers surround41:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi 5.1 Surround output to Front, Center, Rear and Subwoofer speakers iec958:CARD=M2496,DEV=0 M Audio Audiophile 24/96, ICE1712 multi IEC958 (S/PDIF) Digital Audio Output I believe it is a problem with detecting the analogue input/output. Sometimes I can get sound from the device but it is a sheet of white noise and tinkering makes it go away again I don't know if that is a separate problem or if it is linked to not being able to see the analogue input/outputs in the sound preferences. Any help would be greatly appreciated As for the white noise I have installed the Envy24 control panel and spend lots of time playing with the settings but when I can get the white noise I can never get it to an quality where I can actually hear what is being played. The internal speaker plays audio fine and plugging in a NI Audio 4DJ via usb also plays sound, although with some static but I believe that is due to an underpowered usb2 pci expansion card not being able to get enough electricity to the device. Alternatively I have seen other people with problems with this device so it may be a bug in the driver but that is another matter. I would like to get the M-Audio card working so I can begin to enjoy my music once again. As a note, I do not currently have any audio equipment capable of sending or receiving audio via the digital inputs and output so I can not check if they are working. The sound preferences show a wide range of digital in and out options with various surround sound options but no analogue ins and outs.

  • Why did my DocumentRoot change?

    - by Josh K
    My document root (suddenly and unexpectedly) changed to /htdocs from /var/www. This happened after I restarted apache2. The only thing I changed was the httpd.conf file which now reads as follows: <VirtualHost *> ServerName hostname UseCanonicalName ON </VirtualHost> I've greped through the entire /etc directory looking for DocumentRoot and they all say /var/www.

  • bash script with permanent ssh connection

    - by samuelf
    I use a bash script which runs /usr/bin/ssh -f -N -T -L8888:127.0.0.1:3306 [email protected] However, when I run the bash script, it waits.. I see the connection coming up but the script doesn't exit.. it's like it's waiting for the SSH process to finish, because when I manually kill it the bash script finishes as well. Any ideas how to resolve this? UPDATE: I have croned this script.. and the cron process is the one that becomes a zombie.. the actual scripts runs just fine, sorry about that, with ps -auxf I get: root 597 0.0 0.7 2372 912 ? Ss Jul12 0:00 cron root 2595 0.0 0.8 2552 1064 ? S 02:09 0:00 \_ CRON 1001 2597 0.0 0.0 0 0 ? Zs 02:09 0:00 \_ [sh] <defunct> 1001 2603 0.0 0.0 0 0 ?

  • Why are there many processes listed under the same title in htop?

    - by javanix
    Can anyone explain to me why there are sometimes 10 or 15 processes with the same title and "stats" listed in htop? I'm guessing there are multiple threads running - but that many of them obviously couldn't be running concurrently. Is there any sort of performance hit taken if a process uses say, 15 non-concurrent threads vs. 10 non-concurrent threads?

  • SFTP ChRoot result in broken pipe

    - by Patrick Pruneau
    I have a website that I want to add some restricted access to a sub-folder. For this, I've decided to use CHROOT with SFTP (I mostly followed this link : http://shapeshed.com/chroot_sftp_users_on_ubuntu_intrepid/) For now, I've created a user (sio2104) and a group (magento).After following the guide, my folder list look like this : -rw-r--r-- 1 root root 27 2012-02-01 14:23 index.html -rw-r--r-- 1 root root 21 2012-02-01 14:24 info.php drwx------ 15 root root 4096 2012-02-25 00:31 magento As you can see, i've chown root:root the folder magento I wanted to jail-in the user and ...everything else by the way. Also in the magento folder, I chown sio2104:magento everything so they can access what they want. Finally, I've added this to sshd_config file : #Subsystem sftp /usr/lib/openssh/sftp-server Subsystem sftp internal-sftp Match Group magento ChrootDirectory /usr/share/nginx/www/magento ForceCommand internal-sftp AllowTCPForwarding no X11Forwarding no PasswordAuthentication yes #UsePAM yes And the result is...well, I can enter my login, password and it's all finished with a "broken pipe" error. $ sftp [email protected] [....some debug....] [email protected]'s password: debug1: Authentication succeeded (password). Authenticated to 10.20.0.50 ([10.20.0.50]:22). debug1: channel 0: new [client-session] debug1: Requesting [email protected] debug1: Entering interactive session. Write failed: Broken pipe Connection closed Verbose mode gives nothing to help. Anyone have an idea of what I've done wrong? If I try to login with ssh or sftp with my personnal user, everything works fine.

  • VMpalyer: host keyboard layout on guest?

    - by TheDeeno
    I use the dvorak keyboard layout on windows 7. Also, I have a bunch of custom keys mapped using autohotkey. I'm curious, is it possible to have the guest only receive the keyboard events produced by the host? I don't really know how the host communicates keyboard strokes to guests so I don't know how to enable this or if it's possible. Thoughts? Host OS: Win7 x64 Guest: Unbuntu 9.10 x64

  • PHP-FPM chroot mail issues

    - by tubaguy50035
    I'm trying to chroot a site using PHP-FPM. I've been following this post and have done mount --bind for all of those files and folders. When I try to send mail using mail(), it returns false. PHP does have access to usr/sbin/sendmail (which is what my sendmail path is set to in the php.ini), along with the other files mentioned in that post, within the chroot. Anybody have any clues as to what files I'm missing or how to debug further?

  • How can I move my partition in GParted?

    - by reprogrammer
    The following is a screenshot of GParted run on my system. There is a small unallocated space at the beginning of the list. This 1 MiB space is kind of annoying and I'd like to merge with any other partition except /dev/sda1, /dev/sda6 and /dev/sda4. When I right click on the unallocated partition, the only available operation is "New". And, if I click on "New", I get the following error message. It is not possible to create more than 4 primary partitions Any ideas of how to go about merging the small unallocated space with other partitions?

  • Where to find ServerName in a PHP Script

    - by Josh K
    I'm looking to retrieve the ServerName field located in /etc/apache2/apache2.conf. My only issue is then calling it in PHP (echo $_SERVER['SERVER_NAME'];) it gives me not the server name but the ip address. If I pull a phpinfo(); I can the server name under the Hostname:Port field under the apache2handler, so I know it's accessible somehow.

  • Download JDK onto a remote server

    - by itsadok
    I want to get the latest JDK onto a server in a remote location. Downloading the JDK from Sun's website requires jumping through all kinds of hoops until you actually get the file. I'm not sure exactly if they use cookies or my IP address, but simply copying the file URL and trying wget on the server doesn't work. Googling for mirrors of the JDK, I could only find old versions. Right now I'm left with the option of downloading it into my computer, then uploading it to the server. This feels slow and stupid. Anyone got a better idea? EDIT: Thanks for all the replies. Just to clarify, as I'm writing this I'm rsyncing the 78MB file to my server. It should be done in about an hour, so it's not such a big deal. However, since this is not the first time I'm doing this, I was hoping for a better solution for next time. Solution: What I ended up doing was sudo aptitude install lynx-cur www-browser http://java.sun.com/javase/downloads/ From there it's mostly using the arrow and enter keys, and answering "Yes" to a lot of lynx security questions (about cookies and certificates). Thanks to resonator.

  • Permission problem - users can't access main index.php anymore

    - by JMan
    From /var/www, I executed "chmod -R 774 ." and now none of my .php scripts are accessible. From my browser, when I type in mydomain.com or mydomain.com/test2.php or mydomain.com/test.php, I get the 403 Forbidden error msg. So, I changed the permissions of 3 of the .php scripts to 775, but this didn't help either. Here is the output from "ls -la /var/www": drwxrwxr-- 6 john wheel 4096 2010-09-29 17:38 . drwxr-xr-x 14 root root 4096 2010-09-27 21:15 .. -rwxrwxr-x 1 john wheel 3353 2010-09-29 05:29 index.php -rwxrwxr-x 1 john wheel 124 2010-09-27 23:12 .htaccess -rwxrwxr-x 1 john john 34 2010-09-29 17:39 test2.php -rwxrwxr-x 1 john john 26 2010-09-28 22:08 test.php The .htaccess file does a URL mod_rewrite so typing in index.php is not needed.

  • Lockup when unlocking screen saver

    - by chris
    I've had this happen a couple of times - screen saver kicks in, locks the screen, and when I put my password in to unlock it the system just seems to hang. Cursor turns to the busy, HDD light flickers occasionally, but the only thing I can do at that point is power down. This is on a desktop, not a laptop and according to the bios all the power saving is turned off. Has anyone else seen this? Is there a way to prevent it, or at least diagnose the cause?
