  • ubuntu 10.04 + php + postfix

    - by mononym
    I have a server I am running: Ubuntu 10.04 php 5.3.5 (fpm) Nginx I have installed postfix, and set it to loopback-only (only need to send) The problem is it is not sending. if i issue (at command line): echo "testing local delivery" | mail -s "test email to localhost" [email protected] I get the email no problem, but through PHP it does not arrive. When I send it via PHP, mail.log shows: Mar 28 10:15:04 host postfix/pickup[32102]: 435EF580D7: uid=0 from=<root> Mar 28 10:15:04 host postfix/cleanup[32229]: 435EF580D7: message-id=<20120328091504.435EF580D7@FQDN> Mar 28 10:15:04 host postfix/qmgr[32103]: 435EF580D7: from=<root@FQDN>, size=1127, nrcpt=1 (queue active) Mar 28 10:15:04 host postfix/local[32230]: 435EF580D7: to=<root@FQDN>, orig_to=<root>, relay=local, delay=3.1, delays=3/0.01/0/0.09, dsn=2.0.0, status=sent (delivered to maildir) Mar 28 10:15:04 host postfix/qmgr[32103]: 435EF580D7: removed any help appreciated, my main.cf file: smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h readme_directory = no # TLS parameters smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. myhostname = FQDN alias_maps = hash:/etc/aliasesalias_database = hash:/etc/aliases myorigin = /etc/mailname #myorigin = $mydomain mydestination = FQDN, localhost.FQDN, , localhost relayhost = $mydomain mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = loopback-only virtual_alias_maps = hash:/etc/postfix/virtual home_mailbox = mail/

  • ubuntu 9.04 pptp broken after a power failure

    - by kevin42
    I have a small Ubuntu 9.04 router setup as a NAT box and a PPTP server. After a power failure everything except the PPTP server still works. A windows client gets to "registering your computer on the network" but then says Error 742: The remote computer does not support the required data encryption type. I did some research and I think the problem is with the ppp_mppe module. When I try to run 'modprobe ppp_mppe' it hangs indefinitely. What would cause this hang? Any ideas how I can troubleshoot this further? Thanks for the help! UPDATE: I am still having the problem, however I have found some more information. When the first user tries to connect to pptp, the process list shows modprobe sha1 running, and one instance of modprobe ppp_mppe for each connection attempt. If I killall modprobe at this point the next connection attempt works, and everything is fine until the next reboot. I'm planning to do a clean install at some point in the future but I'd really like to get to the real cause of this.

  • Changing PATH Environment Variable for all Users. (Ubuntu)

    - by Wally Glutton
    I recently compiled Ruby Enterprise Edition (REE) on an Ubuntu 8.04 server. I would like to update my PATH to ensure this new version of Ruby (found in /opt/ruby_ee/bin) supersedes the older version in /usr/local/bin. (I still want the old version around, though.) I would like these PATH changes to affect all users and crontabs. 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 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 not affect my PATH at all. Attempted Solution #2: Next I followed these instructions and updated the PATH setting in /etc/login.defs and /etc/crontab. (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 commands "echo $PATH" and "ruby -v". My shell is bash. My .bashrc doesn't override my PATH. Yes, I have heard of the Ruby Version Manager project. ;)

  • Storing secure keys on Ubuntu web server

    - by Sencha
    I'm running Ubuntu 12.04 Precise with a DUNG (Django, Unix, Nginx & Gunicorn) environment and my app (as well as various config files) is stored in a python virtual environment inside /srv, which the www-data user has access to. The nginx & gunicorn processes are all run as www-data. My web app requires secure credentials which I am storing in an environment.sh file. This file contains various exports and is run using source before the gunicorn processes execute. My concern is the location of the environment.sh file and it's permissions. Will it be okay storing this file inside the /srv folder where the www-data has access to it? Or should it be stored and owned by root somewhere else such as /var/myapp/environment.sh? Also, regarding the www-data user, if any of my web processes (which are run as www-data) are compromised and someone gains access to them, does that mean that the user could potentially read any file on the system, even if they can't write? Including my secure keys?

  • Booting Ubuntu as VM with KVM on Ubuntu 12.04

    - by CrazycodeMonkey
    I am trying to boot my very first VM using KVM. I have Ubuntu 12.04 installed, i made sure the BIOS had the right virtualization flag enabled for intel processor by running kvm-ok. I have researched this on google and all the instructions that i have found so far are outdated. for e.g. most instructions talk about booting a virtual machine with the following commands qemu-img create -f qcow2 foo.img 100G --- create a virtual disk for your VM kvm --name foo -m 1024 -hda foo.img -cdrom whatever.iso -boot d -- This runs kvm. This command line is incomplete. First you need to be root to run this. Second- it is missing option for the video device. When you run this command you get the following error "Could not initialize SDL(No available video device) - exiting" Googled this error and looked it up on stackover flow http://stackoverflow.com/questions/4841908/sdl-init-failure-reason-is-no-available-video-device The answer provided here does not work on Ubuntu 12.04 Googled this problem further and found out that i need to specify a video device so I finally ran the following command sudo kvm --name mymachine -m 8096 -hda myimage.img --cdrom ubuntu.iso -boot d -vga cirruss -k en-us -vmc :0 This was after I had created the myimage.img image on the drive. Now this command does not give me an error but it just hangs. Does anyone have clear instructions on how to run a VM using KVM on Ubuntu?

  • Ubuntu + LigHTTPd: Server requests taking ages

    - by ctrl_freak
    I've had an issue since upgrading my distro a couple of weeks ago from hardy; receiving data after making a request has increasing intervals of nothing, as you can see from the picture below. http://i49.tinypic.com/2w5lvr9.png I have since reinstalled fresh from an Ubuntu 10.04 Server (i386) disk, but am still having the same issues. I'm running on a LigHTTPd, MySQL, PHP5 stack. The surprising thing is, that local browsing using lynx is super fast, as expected. Initially, after reinstalling, I copied over the old configuration files from the previous installation, but have since reinstalled LigHTTPd and rebuilt the config file from scratch. The only correlation I could find, was that I attempted installation of ionCube and Zend Optimizer for a script I was testing, however I would think that it could no longer impact seeing I had reinstalled the OS. I have also removed Suhosin just in case, however it had no impact. I'm thinking it possibly has something to do with networking, but I wouldn't know where to start. The server is manually assigned an IP by it's MAC address on the router. The fact that the time seems to be exponential (to a point) worries me. I've tried strace'ing the LigHTTPd and MySQL processes, however I couldn't see anything obvious, not that I'd really know what I'm looking for. RAM and CPU usage don't seem to be out of the ordinary, but I can't say its perfect.. I'm hoping someone has experienced the same, or can point me in a direction, as searching has proved fruitless as I don't know anything specific. Config files can be posted, if requested.

  • Proftpd on Ubuntu - Create directory permission denied (550 ) after upgrade to 9.10

    - by Ian
    Hi all, I am having problems with ProFTPD since I upgraded to Ubuntu 9.10 from 9.04. When I login as my ftp user (userftp) in the terminal I can create dirs fine in their home dir. But when I use ftp as this user permission is denied (550 asl: permission denied) when I try and do the same operation (creating a dir). Uploading files is fine though. I am using the same config for proftpd as I was before, I can't understand what's wrong. Any help appreciated!

  • Help to setup networking in Virtualbox Ubuntu Guest from Windows vista Host

    - by Ramesh Vel
    Hi, I am trying to access the MYSQL installed inside the Ubuntu Guest (In VirtualBox) from my Windows vista Host. It always says not able to find the given IP in the network. I have tried ping the ubuntu virtual machine, but it was not working. So i believe root cause for this is, some bridging between Host & Guest is not enabled. Since i am very new to Ubuntu, am not able to troubleshoot this. Can someone help me out? Cheers

  • Ubuntu for Android on the ASUS Transformer Prime

    - by sola
    I would like to use Ubuntu on my Transformer Prime in parallel with Android (not as a dual booting solution, I want to be able to switch between them instantaniously). I am aware of the traditional chrooting/VNC solution but I heard that it performs very poorly so I would like to use Ubuntu For Android (UFA) which has been announced recently by Canonical. That looks like a polished, highly integrated solution for Android devices. The Prime would be the ideal device for Ubuntu For Android since it has a powerful processor (Tegra3) capable of running a lot of processes in parallel on its 4 cores. Does anyone know if Canonical or anybody else is working on supporting UFA on the ASUS Transformer Prime? As far as I understand, the X11 driver is available for Tegra3 so, the biggest hurdle may be easily overcome.

  • Ubuntu Laptop Screen does not turn on after sleep

    - by Gage
    I recently put Ubuntu 10.10 on my laptop and after fixing the wireless problem I am only stuck on my screen turning back on after sleep. I have had this problem since Ubuntu 7. I tried using Ubuntu way back then and had a whole bunch of issues with the sleep and the wireless(Broadcom 4311). Anyways, I have an ATI Radeon express 200M graphics card (old laptop). When I go to Hardware drivers it doesn't give me any options to use the closed source drivers. Any suggestions on what I should do? I am going to try what is suggested in this thread but I am at work right now. Laptop does not wake up after sleep Thanks in advance for any help.

  • Can't remove Ubuntu Desktop from dropdown menu on logon screen

    - by Bryan
    Hello All, I'm running Ubuntu on an Eee PC with the Netbook interface. I installed Ubuntu Desktop via Aptitude to see how well it works on the Eee PC, and after a while I wanted to rid myself of it. So, I purged it using Aptitude, but it still shows up as an option in the dropdown menu on the login screen. Is there any way I can remove the Ubuntu Desktop option from the dropdown menu? It's not a big deal I guess... I'm just curious now how to do it. :)

    How to load Xmir on Ubuntu 13.10 Nexus 7 tablet, unity8 + lightdm + mir, unity-system-compositor + Xorg installed. Still getting message above after system reboot in the /var/log/Xorg.0.log : [ 81.542] (II) "glx" will be loaded by default. [ 81.542] (WW) "xmir" is not to be loaded by default. Skipping. [ 81.542] (II) LoadModule: "dri2" Thanks Note: No, this question is not duplicate with How to load Xmir on Ubuntu 13.10 because. My note that this do not work on Ubuntu Touch Saucy + Nexus7 tablet was removed by fossfreedom. I do feel it duplicate also, but this moderator issue. There is no chance to response on equal topic, even when it is not obviously solving the problem. I do consider this confusing and causing incomplete answers.

  • Ubuntu Natty: 32-bit userland, 64-bit kernel?

    I'm trying to manually install a 64-bit kernel for 32-bit Ubuntu. I have my reasons for doing so, but they're too complicated to explain here. Prior to Natty, this worked fine.

  • sendmail on ubuntu (9.10) machine "stopped" sending mail

    - by Doron
    I'm developing on my ubuntu 9.10 machine for the web (php). I'm using it sendmail for sending mails, and while developing on my local machine, I send local mails (to my user 'doron'). Up until a few days ago, I was able to send mails both from php's mail() function, and from the command line using the mail command. I'm using sendmail with mailutils. Since the last few days, it seems like it stopped working. When I try to send mail from the command line, I get the following in my syslog (and mail.info, and mail.log): Mar 3 13:27:58 doron-desktop sendmail[4693]: o23BRwlA004693: from=doron, size=84, class=0, nrcpts=1, msgid=<201003031127.o23BRwlA004693@doron-desktop.>, relay=doron@localhost Mar 3 13:27:58 doron-desktop sm-mta[4694]: o23BRwtQ004694: ruleset=check_rcpt, arg1=<doron@doron-desktop>, relay=localhost [127.0.0.1], reject=553 5.1.8 <doron@doron-desktop>...

  • How to impove Ubuntu performance on netbook

    - by Alexey Shytikov
    Most recent Ubuntu 12.04 seems to be quite nice and Unity (3D/2D) works fine for me, however not on my old Acer Aspire One any more. There was a times, when I switched from Windows XP to Ubuntu and was happy about system looks, effects and speed... now I attend to think that XP was really great comparing with 12.04. I have found similar questions here but no reasonable answer: how to lower CPU usage for Unity (3D/2D) and memory consumption for Ubuntu 12.04. With new interface I could not find how to disable background services... It's Linux, it's should be the way to optimize without buying new PC... Please share your recipe!

    A friend just complained to me about Ubuntu being slow. Although I've noticed a certain lack of snappiness with Linux vs Windows in the past, I really can't say I've had much to grumble about with the recent distributions of Ubuntu. That said, his objections seem much worse than the ones I used to have and I know that his current setup is significantly more powerful than my laptop. And then it turned out he is running Ubuntu off an external HDD hooked up via USB2.0. The HD enclosure is USB3.0 but apparently he can't manage to get it to boot on USB3.0 so he switched to one of the USB2.0 ports or whatever and that works, albeit not very well. Now I would expect USB to add some overhead to communication between the computer and the HDD; SATA is after all designed to get the maximum out of a hard drive, whereas USB is, well, universal. What are your expreriences with booting off external HDDs? Edit: Does anybody know just how much of a slowdown can be expected?

  • sendmail on ubuntu (9.10) machine "stopped" sending mail

    - by Doron
    I'm developing on my ubuntu 9.10 machine for the web (php). I'm using it sendmail for sending mails, and while developing on my local machine, I send local mails (to my user 'doron'). Up until a few days ago, I was able to send mails both from php's mail() function, and from the command line using the mail command. I'm using sendmail with mailutils. Since the last few days, it seems like it stopped working. When I try to send mail from the command line, I get the following in my syslog (and mail.info, and mail.log): Mar 3 13:27:58 doron-desktop sendmail[4693]: o23BRwlA004693: from=doron, size=84, class=0, nrcpts=1, msgid=<201003031127.o23BRwlA004693@doron-desktop.>, relay=doron@localhost Mar 3 13:27:58 doron-desktop sm-mta[4694]: o23BRwtQ004694: ruleset=check_rcpt, arg1=<doron@doron-desktop>, relay=localhost [127.0.0.1], reject=553 5.1.8 <doron@doron-desktop>...

  • Ubuntu install doesn't recognize kingston SSDnow sv 200 90g

    - by Quique Garcia
    I'm trying install Ubuntu 12.04 on my new Kingston SSD Now SVP200S3/90G, but the installer doesn't list this disk to be installed. However gparted let me do any partitioning operation correctly. I've tryed with Ubuntu Studio and Ubuntu Desktop on different machines: Lenovo ThinkPad T400, Lenovo ThinkStation C20, MoBo ASUS Crosshair V formula. SATA controller in all machines has been set to AHCI and IDE operation and different SATA ports with no luck. The firmware on the SSD has been updated to V.503xxx (latest on kingston page) Any help is appreciated, regards!

  • How to troubleshoot Ubuntu One in Maverick beta?

    - by greggory.hz
    I just updated to the Maverick beta (actually it's a fresh install, and not an upgrade of 10.04). But now "Ubuntu One" doesn't show up in my me-menu thing. In addition, when I go to Ubuntu One from System-Preferences and attempt to log in from there it will sometimes look like it works, but other times it won't do anything. When I go to the command line and type u1sdtool -s it will either say something like "doing auth dance" or "auth failed" and often it has never even prompted me to log in or try to get a new password (even though I know it's correct). Anyway, this is the main hangup I have with the Maverick beta. I can't get to my ubuntu one account from the native client. Is this a widespread issue? Is there something I can do to fix this?

  • Slow internet browsing in Ubuntu

    - by Mark
    I have a dual boot set up with windows and ubuntu, when I'm using windows internet browsing is a lot faster than when I'm using ubuntu and I don't know why. It's like there's just a big latency rather than the maximum speed is lower, there's a big delay before anything happens when using Ubuntu, it happens with all websites all the time. I've never configured the internet connection because it just worked straight away. I have broadband connection through a router shared with some other computers, when we set up the router and internet connection everything was done with windows. Any ideas on what I could do to fix this? Thanks to anyone who replies.

  • adjust resolution on Ubuntu Server 10.04?

    - by Mike Grace
    Installed Ubuntu Server 10.04 on an old laptop and I noticed that the system is trying to show the CLI below my screen. This means that if I run a script or a program with a bunch of output, once it is done, I have to press return several times to bring the output to the point where I can actually see it on the screen. I also have to clear the screen to be able to see what I am typing at the current command prompt. The laptop is an EliteGroup 536S with a native screen resolution of 1024 x 768 How can I adjust the resolution for Ubuntu Server 10.04? What file do I need to edit if editing a file is the solution? I've seen posts on how to change the resolution on the desktop version of Ubuntu but not the server version.

  • Install Ubuntu or Kubuntu?

    - by squallbayu
    I want to upgrade my Ubuntu Lucid to Kubuntu Maverick (with a fresh install of course). I want to try KDE, but I have heard there are slight issues with the native QT applications compared to the GTK application equivalents - such as nvidia-settings, Gimp, Ubuntu Software Centre, and especially th eSynaptic package manager (which in detail showed the administration package / KPackageKit is not powerful yet than synaptic) I believe we can have run GTK+ applications in KDE, but GTK+ applications do not blend with the KDE desktop. Also Java does not provide a GUI for KDE/QT. Should I install Kubuntu (KDE / QT) or stay with ubuntu (GNOME / GTK +)?
