  • what is best multi-server configuration with OpenVPN

    - by sebut
    We have a number of Database severs running MongoDB on Debian plus a number of Application servers also on Debian. The db servers hold replicating db clusters, so they need to talk to each other. Application servers need to talk to all db servers (for reasons of fault tolerance). The servers are potentially spread across multiple hosting centers, so we need secure channels between all servers. The number of servers is bound to grow, so we need a VPN solution that's easy to maintain and expand. This is why I feel that SSH that we use for testing might not be up to the task and OpenVPN seems the way to go. I have ruled out TAP, since I understand that this would mean all traffic going to all the servers - perhaps this is a misunderstanding and TAP acts more like a switch? With TUN devices I imagine that all DB servers would live in their own separate subnet, they would also need a client configured to be able to connect to each of their peers. The application servers could live in a common subnet range with a client config only. Does this sound like a reasonable setup? Strangely, on the web I did not find anything about multi-server with OpenVPN. Thanks for all insights and ideas!

  • BYOD (accessing files) on a domain without joining?

    - by Philip White
    I run a Samba 4 instance at a small private school. This makes a regular Linux server appear as a directory controller. There are two relevant benefits to this: I have a Samba share for people's documents, and I use the Redirected Folders feature to allow any employee to sit down at any PC, log in with their domain credentials, and their My Documents points to network storage. Everyone has a mapped drive (using Group Policy Preferences) to a share specific to their account type. Students can access one share (one share for all students), teachers have another, and office staff have another. However, I would like to allow BYOD (Bring Your Own Device). Some employees are already asking for it with their personal laptops, and I know eventually most everyone will want to. Is there any way to replicate the two features above without having to join PCs to the domain? Joining personal PCs is impractical if only because only professional editions of Windows support this. Ideally, any operating system (including mobile) could access the relevant shares, but of course Windows is key. Offline caching is optional. (I could set up OpenVPN for teachers who want to access their files from home.) The problem with simply giving SSH access to the relevant shares is primarily that Samba 4 relies on ext4 ACLs and ext4 extended attributes to maintain NTFS permissions. Writing files directly to the Linux server would bypass this and would (probably) not be interoperable with Samba4. Right now I am completely flexible. I am even fine with scrapping the whole domain and using some other software for the two features above. How can I allow school employees and students freedom to securely share files without requiring everyone to have specific editions of Windows?

  • Weird vps server issue

    - by anon-user0
    I have an unmanaged linux vps Ubuntu 11.10 (Oneiric Ocelot). I have LNMP installed. Also php-fpm php-apc, varnish, memcache. I have (or rather had) several live sites on it. under normal load the server uses ~700 mb memory. But since last night its using only 20mb~ memory and a lot of the services seems to be down (according to htop) I only see nginx working and mysql starts up and goes does every few minutes on a loop. Here are some information on the server that might help you help me: root@server:~# uname -a Linux server 2.6.18-308.el5.028stab099.3 #1 SMP Wed Mar 7 15:56:00 MSK 2012 i686 i686 i386 GNU/Linux - root@server:~# ifconfig -a lo Link encap:Local Loopback LOOPBACK MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:127.0.0.2 P-t-P:127.0.0.2 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 RX packets:12515 errors:0 dropped:0 overruns:0 frame:0 TX packets:9541 errors:0 dropped:1 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:7191214 (7.1 MB) TX bytes:536726 (536.7 KB) venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:176.31.158.78 P-t-P:176.31.158.78 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 - root@server:~# netstat -l Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 *:http-alt *:* LISTEN tcp 0 0 *:ssh *:* LISTEN tcp6 0 0 [::]:http-alt [::]:* LISTEN tcp6 0 0 [::]:ssh [::]:* LISTEN Active UNIX domain sockets (only servers) Proto RefCnt Flags Type State I-Node Path unix 2 [ ACC ] STREAM LISTENING 9307368 @/com/ubuntu/upstart - htop: http://i.stack.imgur.com/NHKYX.png EDIT: Stressed. mind was not working adding log: root@server:~# less /var/log/syslog Jun 27 05:27:42 server syslogd 1.5.0#6ubuntu1: restart.

  • Closer look at the SOA 12c Feature: Oracle Managed File Transfer

    - by Tshepo Madigage-Oracle
    The rapid growth of cloud-based applications in the enterprise, combined with organizations' desire to integrate applications with mobile technologies, is dramatically increasing application integration complexity. To meet this challenge, Oracle introduced Oracle SOA Suite 12c, the latest version of the industry's most complete and unified application integration and SOA solution. With simplified cloud, mobile, on-premises, and Internet of Things (IoT) integration capabilities, all within a single platform, Oracle SOA Suite 12c helps organizations speed time to integration, improve productivity, and lower TCO. To extend its B2B solution capabilities with Oracle SOA Suite 12c, Oracle unveiled Oracle Managed File Transfer, an integrated solution that enables organizations to virtually eliminate file transfer complexities. This allows customers to load data securely into Oracle Cloud applications as well as third-party cloud or partner applications. Oracle Managed File Transfer (Oracle MFT) enables secure file exchange and management with internal departments and external partners. It protects against inadvertent access to unsecured files at every step in the end-to-end transfer of files. It is easy to use especially for non technical staff so you can leverage more resources to manage the transfer of files. The extensive reporting capabilities allow you to get quick status of a file transfer and resubmit it as required. You can protect data in your DMZ by using the SSH/FTP reverse proxy. Oracle Managed File Transfer can help integrate applications by transferring files between them in complex use case patterns. Standalone: Transferring files on its own using embedded FTP and sFTP servers and the file systems to which it has access. SOA Integration: a SOA application can be the source or target of a transfer. A SOA application can also be the common endpoint for the target of one transfer and the source of another. B2B Integration: B2B application can be the source or target of a transfer. A B2B application can also be the common endpoint for the target of one transfer and the source of another. Healthcare Integration:  Healthcare application can be the source or target of a transfer. A Healthcare application can also be the common endpoint for the target of one transfer and the source of another. Oracle Service Bus (OSB) integration: OMT can integrate with Oracle Service Bus web service interfaces. OSB interface can be the source or target of a transfer. An Oracle Service Bus interface can also be the common endpoint for the target of one transfer and the source of another. Hybrid Integration: can be one participant in a web of data transfers that includes multiple application types. Oracle Managed File Transfers has four user roles: file handlers, designers, monitors, and administrators. File Handlers: - Copy files to file transfer staging areas, which are called sources. - Retrieve files from file transfer destinations, which are called targets. Designers: - Create, read, update and delete file transfer sources. - Create, read, update and delete file transfer targets. - Create, read, update and delete transfers, which link sources and targets in complete file delivery flows. - Deploy and test transfers. Monitors: - Use the Dashboard and reports to ensure that transfer instances are successful. - Pause and resume lengthy transfers. - Troubleshoot errors and resubmit transfers. - View artifact deployment details and history. - View artifact dependence relationships. - Enable and disable sources, targets, and transfers. - Undeploy sources, targets, and transfers. - Start and stop embedded FTP and sFTP servers. Administrators: - All file handler tasks - All designer tasks - All monitor tasks - Add other users and determine their roles - Configure user directory permissions - Configure the Oracle Managed File Transfer server - Configure embedded FTP and sFTP servers, including security - Configure B2B and Healthcare domains - Back up and restore the Oracle Managed File Transfer configuration - Purge transferred files and instance data - Archive and restore instance data and payloads - Import and export metadata You will find all the related information about SOA 12.1.3.

  • ls -l freezes terminal locally and remotely

    - by Jakobud
    I've been reading other SF threads regarding ls not returning results or freezing and stalling terminal sessions and it appears they usually the fault of network problems. My problem however, occurs both over remote SSH sessions but also if I am physically at the server itself... I just installed CentOS 5.4 on one of our servers. I'm setting up some rdiff-backup scripts and when I downloaded librsync and untared it, thats when I started seeing some weird behavior with ls -l. wget http://sourceforge.net/projects/librsync/files/librsync/0.9.7/librsync-0.9.7.tar.gz/download /tmp cd /tmp tar -xzf librsync-0.9.7.tar.gz Simple enough. To view the files in this directory I did this: ls results: librsync-0.9.7 librsync-0.9.7.tar.gz Now, if I ls -l, my terminal freezes. I have to re-ssh in to keep going. After reading SF threads, I thought it was network related. So I was extremely surprised to go sit down at the server itself and see the exact same thing happen... So its obviously not a network issues. Even if I ls /tmp/librsync-0.9.7, my terminal freezes just the same... Next I did an strace and got this (warning: wall of text coming....): strace ls -l /tmp execve("/bin/ls", ["ls", "-l", "/tmp"], [/* 21 vars */]) = 0 brk(0) = 0x1c521000 mmap(NULL, 4096,

  • Prepping the Raspberry Pi for Java Excellence (part 1)

    - by HecklerMark
    I've only recently been able to begin working seriously with my first Raspberry Pi, received months ago but hastily shelved in preparation for JavaOne. The Raspberry Pi and other diminutive computing platforms offer a glimpse of the potential of what is often referred to as the embedded space, the "Internet of Things" (IoT), or Machine to Machine (M2M) computing. I have a few different configurations I want to use for multiple Raspberry Pis, but for each of them, I'll need to perform the following common steps to prepare them for their various tasks: Load an OS onto an SD card Get the Pi connected to the network Load a JDK I've been very happy to see good friend and JFXtras teammate Gerrit Grunwald document how to do these things on his blog (link to article here - check it out!), but I ran into some issues configuring wi-fi that caused me some needless grief. Not knowing if any of the pitfalls were caused by my slightly-older version of the Pi and not being able to find anything specific online to help me get past it, I kept chipping away at it until I broke through. The purpose of this post is to (hopefully) help someone else recognize the same issues if/when they encounter them and work past them quickly. There is a great resource page here that covers several ways to get the OS on an SD card, but here is what I did (on a Mac): Plug SD card into reader on/in Mac Format it (FAT32) Unmount it (diskutil unmountDisk diskn, where n is the disk number representing the SD card) Transfer the disk image for Debian to the SD card (dd if=2012-08-08-wheezy-armel.img of=/dev/diskn bs=1m) Eject the card from the Mac (diskutil eject diskn) There are other ways, but this is fairly quick and painless, especially after you do it several times. Yes, I had to do that dance repeatedly (minus formatting) due to the wi-fi issues, as it kept killing the ability of the Pi to boot. You should be able to dramatically reduce the number of OS loads you do, though, if you do a few things with regard to your wi-fi. Firstly, I strongly recommend you purchase the Edimax EW-7811Un wi-fi adapter. This adapter/chipset has been proven with the Raspberry Pi, it's tiny, and it's cheap. Avoid unnecessary aggravation and buy this one! Secondly, visit this page for a script and instructions regarding how to configure your new wi-fi adapter with your Pi. Here is the rub, though: there is a missing step. At least for my combination of Pi version, OS version, and uncanny gift of timing and luck there was. :-) Here is the sequence of steps I used to make the magic happen: Plug your newly-minted SD card (with OS) into your Pi and connect a network cable (for internet connectivity) Boot your Pi. On the first boot, do the following things: Opt to have it use all space on the SD card (will require a reboot eventually) Disable overscan Set your timezone Enable the ssh server Update raspi-config Reboot your Pi. This will reconfigure the SD to use all space (see above). After you log in (UID: pi, password: raspberry), upgrade your OS. This was the missing step for me that put a merciful end to the repeated SD card re-imaging and made the wi-fi configuration trivial. To do so, just type sudo apt-get upgrade and give it several minutes to complete. Pour yourself a cup of coffee and congratulate yourself on the time you've just saved.  ;-) With the OS upgrade finished, now you can follow Mr. Engman's directions (to the letter, please see link above), download his script, and let it work its magic. One aside: I plugged the little power-sipping Edimax directly into the Pi and it worked perfectly. No powered hub needed, at least in my configuration. To recap, that OS upgrade (at least at this point, with this combination of OS/drivers/Pi version) is absolutely essential for a smooth experience. Miss that step, and you're in for hours of "fun". Save yourself! I'll pick up next time with more of the Java side of the RasPi configuration, but as they say, you have to cross the moat to get into the castle. Hopefully, this will help you do just that. Until next time! All the best, Mark

  • Motorola Droid App Recommendations

    - by Brian Jackett
    Just as a disclaimer, the views and opinions expressed in this post are solely my own and I’m not getting paid or compensated for anything.     Ok, so I’m one of the crazy few who went out and bought a Droid the week it was released a few months back.  The Motorola Droid was a MAJOR upgrade in phone capabilities for me as my previous phone had no GPS, no web access, limited apps, etc.  I now use my Droid for so much of my life from work to personal to community based events.  Since I’ve been using my Droid for awhile, a number of friends (@toddklindt, @spmcdonough, @jfroushiii, and many more) who later got a Droid asked me which apps I recommended.  While there are a few sites on the web listing out useful Android apps, here’s my quick list (with a few updates since first put together.) Note: * denotes a highly recommended app     Android App Recommendations for Motorola Droid (Updated after 2.1 update) RemoteDroid – install a thin client on another computer and Droid becomes mouse pad / keyboard, control computer remotely PdaNet – free version allows tethering (only to HTTP, no HTTPS) without paying extra monthly charge.  A paid version allows HTTPS access. SportsTap – keep track of about a dozen sports, favorite teams, etc *Movies – setup favorite theaters, find movie times, buy tickets, etc WeatherBug elite – paid app, but gives weather alerts, 4 day forecast, etc.  Free version also exists.  (Update: Android 2.1 offers free weather app, but I still prefer WeatherBug.) *Advanced Task Killer – manually free up memory and kill apps not needed Google Voice – have to have a Google Voice account to really use, but allows visual voice mail, sending calls to specific phones, and too many other things to list AndroZip – access your phone memory like a file system Twidroid – best Twitter client I’ve found so far, but personal preference varies.  I’m using free version and suits me just fine. Skype (beta) – I only use this to send chat messages, not sure how/if phone calls works on this. (Update: Skype Mobile app just released, but uninstalled after few days as it kept launching in background and using up memory when not wanted.) *NewsRob – RSS reader syncs to Google Reader.  I use this multiple times a day, excellent app. (Update: this app does ask for your Google username and password, so security minded folks be cautioned.) ConnectBot – don’t use often myself, but allows SSH into remote computer.  Great if you have a need for remote manage server. Speed Test – same as the online website, allows finding upload/download speeds. WiFinder – store wifi preferences and find wifi spots in area. TagReader – simple Microsoft Tag Reader, works great. *Google Listen – audible podcast catcher that allows putting items into a queue, sync with Google Reader RSS, etc. I personally love this app which has now replaced the iPod I used to use in my car, but have heard mixed reviews from others. Robo Defense – (paid app) tower defense game but with RPG elements to upgrade towers over lifetime playing. I’ve never played FieldRunners but I’m told very similar in offering. Nice distraction when in airport or have some time to burn. Phit Droid 3rd Edition – drag and drop block shapes into a rectangle box, simple game to pass the time with literally 1000s of levels. Note this game has been updated dozens of times with numerous editions so unsure exactly which are still on the market. Google Sky Map – impress your friends by holding Droid up to sky and viewing constellations using Droid screen. wootCheck Lite – check up on daily offerings on Woot.com and affiliated wine, sellout, shirt, and kids sites.   Side notes: I’ve seen that Glympse and TripIt have recently come out with Android apps.  I’ve installed but haven’t gotten to use either yet, but I hear good things.  Will try out on 2 upcoming trips in May and update with impressions.         -Frog Out   Image linked from http://images.tolmol.com/images/grpimages/200910191814100_motorola-droid.gif

  • Using the SOA-BPM VIrtualBox Appliance

    - by antony.reynolds
    Quickstart Guide to Using Oracle Appliance for SOA/BPM Recently I have been setting up some machines for fellow engineers.  My base setup consists of Oracle Enterprise Linux with Oracle Virtual Box.  Note that after installing VirtualBox I needed to add the VirtualBox Extension Pack to enable RDP access amongst other features.  In order to get them started quickly with some images I downloaded the pre-built appliance for SOA/BPM from OTN. Out of the box this provides a VirtualBox image that is pre-installed with everything you will need to develop SOA/BPM applications. Specifically by using the virtual appliance I got the following pre-installed and configured. Oracle Enterprise Linux 5 User oracle password oracle User root password oracle. Oracle Database XE Pre-configured with SOA/BPM repository. Set to auto-start on OS startup. Oracle SOA Suite 11g PS2 Configured with a “collapsed domain”, all services (SOA/BAM/EM) running in AdminServer. Listening on port 7001 Oracle BPM Suite 11g Configured in same domain as SOA Suite. Oracle JDeveloper 11g With SOA/BPM extensions. Networking The VM by default uses NAT (Network Address Translation) for network access.  Make sure that the advanced settings for port forwarding allow access through the host to guest ports.  It should be pre-configured to forward requests on the following ports Purpose Host Port Guest Port (VBox Image) SSH 2222 22 HTTP 7001 7001 Database 1521 1521 Note that only one VirtualBox image can use a given host port, so make sure you are not clashing if it seems not to work. What’s Left to Do? There is still some customization of the environment that may be required. If you need to configure a proxy server as I did then for the oracle and root users to set up an HTTP proxy Added “export http_proxy=http://proxy-host:proxy-port” to ~oracle/.bash_profile and ~root/.bash_profile Added “export http_proxy=http://proxy-host:proxy-port” to /etc/.bashrc Edited System->Preferences to set Network Proxy In Firefox set Preferences->Network->Connection Settings to “Use system proxy settings” In JDeveloper set Edit->Preferences->Web Browser and Proxy to required proxy settings You may need to configure yum to point to a public OEL yum repository – such as http://public-yum.oracle.com. If you are going to be accessing the SOA server from outside the VirtualBox image then you may want to set the soa-infra Server URLs to be the hostname of the host OS. Snap! Once I had the machine configured how I wanted to use it I took a snapshot so that I can always get back to the pristine install I have now.  Snapshots are one of the big benefits of putting a development environment into a virtualized environment.  I can make changes to my installation and if I mess it up I can restore the image to a last known good snapshot. Hey Presto!, Ready to Go This is the quickest way to get up and running with SOA/BPM Suite.  Out of the box the download will work, I only did extra customization so I could use services outside the firewall and browse outside the firewall from within by SOA VirtualBox image.  I also use yum to update the OS to the latest binaries. So have fun.

  • Ubuntu 12.04 // Likewise Open // Unable to ever authenticate AD users

    - by Rob
    So Ubuntu 12.04, Likewise latest from the beyondtrust website. Joins domain fine. Gets proper information from lw-get-status. Can use lw-find-user-by-name to retrieve/locate users. Can use lw-enum-users to get all users. Attempting to login with an AD user via SSH generates the following errors in the auth.log file: Nov 28 19:15:45 hostname sshd[2745]: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared object file: No such file or directory Nov 28 19:15:45 hostname sshd[2745]: PAM adding faulty module: pam_winbind.so Nov 28 19:15:51 hostname sshd[2745]: error: PAM: Authentication service cannot retrieve authentication info for DOMAIN\\user.name from remote.hostname Nov 28 19:16:06 hostname sshd[2745]: Connection closed by 10.1.1.84 [preauth] Attempting to login via the LightDM itself generates similar errors in the auth.log file.

The errors obviously are correct, the file /lib/security/pam_winbind.so does not exist. If its a dependancy/required, surely it should be part of the package? I've installed/reinstalled, I've used the downloaded package from the beyondtrust website, i've used the repository, nothing seems to work, every method of installing this application generates the same errors for me. UPDATE : Hrmm, I thought likewise didn't use native winbind but its own modules. Installing winbind from apt-get uninstalls pbis-open (likewise) and generates failures when installing if pbis-open is installed first. Uninstalled winbind, reinstalled pbis-open, same issue as above. The file pam_winbind.so does not exist in that location. Setting up pbis-open-legacy (7.0.1.918) ... Installing Packages was successful This computer is joined to DOMAIN.LOCAL New libraries and configurations have been installed for PAM and NSS. Clearly it thinks it has installed it, but it hasn't. It may be a legacy issue with the previous attempt to configure domain integration manually with winbind. Does anyone have a working likewise-open installation and does the /etc/nsswitch.conf include references to winbind? Or do the /etc/pam.d/common-account or /etc/pam.d/common-password reference pam_winbind.so? I'm unsure if those entries are just legacy or setup by likewise. UPDATE 2 : Complete reinstall of OS fixed it and it worked seamlessly, like it was meant to and those 2 PAM files did NOT include entries for pam_winbind.so, so that was the underlying problem. Thanks for the assist.

  • How do I get sound output on HDMI without the need to start X?

    - by Magnus Hoff
    I have a headless machine connected to my sound system, and I am using it to run a music playing daemon that I control over the network. (Among other things) However, I can't seem to be able to have sound come out of my speakers without running X. I am running pulse audio in a system wide instance and my daemon is not running within X. Nevertheless, when my daemon is playing music without me hearing it, I can fix it by running startx in an unrelated session. After X starts, I can hear the sound. The sound disappears again if I kill the X server. Interestingly/annoyingly, the sound also stops after X has been running for a few minutes. This could possibly be because of a screen saver of some sort, but I haven't been able to verify or falsify this theory. So my current workaround is to ssh into the box whenever I want music and startx, and restart it every fifteen minutes or so. I'd like to do better. I have been able to verify the following: Adjustments in alsamixer have no effect on this problem. The relevant output channel is never muted In alsamixer, I can see no difference between when the sound is working and when it isn't Nothing is muted in pactl list There is no difference in the output from pactl list between before starting X and after it's started. (Except the identifier of the pactl instance connected to pulse, which is different each time you run pactl) The user running the music daemon is a member of the groups audio, pulse and pulse-access The music daemon program does not report any error messages and acts as if it is playing the music like it should Some form of dbus daemon is running. ps aux|grep dbus reports dbus-daemon --system --fork --activation=upstart before and after I have started X Some details about my hardware: Motherboard: http://www.asus.com/Motherboards/AT5IONTI_DELUXE/ Sound chip: Nvidia GPU 0b HDMI/DP (from alsamixer) Using HDMI for output (Machine also has an Intel Realtek ALC887 that I am not using) Output of lsmod: Module Size Used by deflate 12617 0 zlib_deflate 27139 1 deflate ctr 13201 0 twofish_generic 16635 0 twofish_x86_64_3way 25287 0 twofish_x86_64 12907 1 twofish_x86_64_3way twofish_common 20919 3 twofish_generic,twofish_x86_64_3way,twofish_x86_64 camellia 29348 0 serpent 29125 0 blowfish_generic 12530 0 blowfish_x86_64 21466 0 blowfish_common 16739 2 blowfish_generic,blowfish_x86_64 cast5 25112 0 des_generic 21415 0 xcbc 12815 0 rmd160 16744 0 bnep 18281 2 rfcomm 47604 12 sha512_generic 12796 0 crypto_null 12918 0 parport_pc 32866 0 af_key 36389 0 ppdev 17113 0 binfmt_misc 17540 1 nfsd 281980 2 ext2 73795 1 nfs 436929 1 lockd 90326 2 nfsd,nfs fscache 61529 1 nfs auth_rpcgss 53380 2 nfsd,nfs nfs_acl 12883 2 nfsd,nfs sunrpc 255224 16 nfsd,nfs,lockd,auth_rpcgss,nfs_acl btusb 18332 2 vesafb 13844 2 pl2303 17957 1 ath3k 12961 0 bluetooth 180153 24 bnep,rfcomm,btusb,ath3k snd_hda_codec_hdmi 32474 4 nvidia 11308613 0 ftdi_sio 40679 1 usbserial 47113 6 pl2303,ftdi_sio psmouse 97485 0 snd_hda_codec_realtek 224173 1 snd_hda_intel 33719 5 snd_hda_codec 127706 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel serio_raw 13211 0 snd_seq_midi 13324 0 snd_hwdep 17764 1 snd_hda_codec snd_pcm 97275 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec snd_rawmidi 30748 1 snd_seq_midi snd_seq_midi_event 14899 1 snd_seq_midi snd_seq 61929 2 snd_seq_midi,snd_seq_midi_event snd_timer 29990 2 snd_pcm,snd_seq snd_seq_device 14540 3 snd_seq_midi,snd_rawmidi,snd_seq snd 79041 20 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device asus_atk0110 18078 0 mac_hid 13253 0 jc42 13948 0 soundcore 15091 1 snd snd_page_alloc 18529 2 snd_hda_intel,snd_pcm coretemp 13554 0 i2c_i801 17570 0 lp 17799 0 parport 46562 3 parport_pc,ppdev,lp r8169 62154 0 Any ideas?

  • Terminal Colors Not Working

    - by Matt Fordham
    I am accessing an Ubuntu 10.04.2 LTS server via SSH from OSX. Recently the colors stopped working. I think it happened while I was installing/troubleshooting RVM, but I am not positive.

  • How can I make sound work without starting X?

    - by Magnus Hoff
    I have a headless machine connected to my sound system, and I am using it to run a music playing daemon that I control over the network. (Among other things) However, I can't seem to be able to have sound come out of my speakers without running X. I am running pulse audio in a system wide instance and my daemon is not running within X. Nevertheless, when my daemon is playing music without me hearing it, I can fix it by running startx in an unrelated session. After X starts, I can hear the sound. The sound disappears again if I kill the X server. Interestingly/annoyingly, the sound also stops after X has been running for a few minutes. This could possibly be because of a screen saver of some sort, but I haven't been able to verify or falsify this theory. So my current workaround is to ssh into the box whenever I want music and startx, and restart it every fifteen minutes or so. I'd like to do better. I have been able to verify the following: Adjustments in alsamixer have no effect on this problem. The relevant output channel is never muted In alsamixer, I can see no difference between when the sound is working and when it isn't Nothing is muted in pactl list There is no difference in the output from pactl list between before starting X and after it's started. (Except the identifier of the pactl instance connected to pulse, which is different each time you run pactl) The user running the music daemon is a member of the groups audio, pulse and pulse-access The music daemon program does not report any error messages and acts as if it is playing the music like it should Some form of dbus daemon is running. ps aux|grep dbus reports dbus-daemon --system --fork --activation=upstart before and after I have started X Some details about my hardware: Motherboard: http://www.asus.com/Motherboards/AT5IONTI_DELUXE/ Sound chip: Nvidia GPU 0b HDMI/DP (from alsamixer) Using HDMI for output (Machine also has an Intel Realtek ALC887 that I am not using) Output of lsmod: Module Size Used by deflate 12617 0 zlib_deflate 27139 1 deflate ctr 13201 0 twofish_generic 16635 0 twofish_x86_64_3way 25287 0 twofish_x86_64 12907 1 twofish_x86_64_3way twofish_common 20919 3 twofish_generic,twofish_x86_64_3way,twofish_x86_64 camellia 29348 0 serpent 29125 0 blowfish_generic 12530 0 blowfish_x86_64 21466 0 blowfish_common 16739 2 blowfish_generic,blowfish_x86_64 cast5 25112 0 des_generic 21415 0 xcbc 12815 0 rmd160 16744 0 bnep 18281 2 rfcomm 47604 12 sha512_generic 12796 0 crypto_null 12918 0 parport_pc 32866 0 af_key 36389 0 ppdev 17113 0 binfmt_misc 17540 1 nfsd 281980 2 ext2 73795 1 nfs 436929 1 lockd 90326 2 nfsd,nfs fscache 61529 1 nfs auth_rpcgss 53380 2 nfsd,nfs nfs_acl 12883 2 nfsd,nfs sunrpc 255224 16 nfsd,nfs,lockd,auth_rpcgss,nfs_acl btusb 18332 2 vesafb 13844 2 pl2303 17957 1 ath3k 12961 0 bluetooth 180153 24 bnep,rfcomm,btusb,ath3k snd_hda_codec_hdmi 32474 4 nvidia 11308613 0 ftdi_sio 40679 1 usbserial 47113 6 pl2303,ftdi_sio psmouse 97485 0 snd_hda_codec_realtek 224173 1 snd_hda_intel 33719 5 snd_hda_codec 127706 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel serio_raw 13211 0 snd_seq_midi 13324 0 snd_hwdep 17764 1 snd_hda_codec snd_pcm 97275 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec snd_rawmidi 30748 1 snd_seq_midi snd_seq_midi_event 14899 1 snd_seq_midi snd_seq 61929 2 snd_seq_midi,snd_seq_midi_event snd_timer 29990 2 snd_pcm,snd_seq snd_seq_device 14540 3 snd_seq_midi,snd_rawmidi,snd_seq snd 79041 20 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device asus_atk0110 18078 0 mac_hid 13253 0 jc42 13948 0 soundcore 15091 1 snd snd_page_alloc 18529 2 snd_hda_intel,snd_pcm coretemp 13554 0 i2c_i801 17570 0 lp 17799 0 parport 46562 3 parport_pc,ppdev,lp r8169 62154 0 Any ideas?

  • Type of computer for a developer on the road

    - by nabucosound
    Hi developers: I am planning to be traveling through eurasia and asia (russia, china, korea, japan, south east asia...) for a while and, although there are plenty of marvelous things to see and to do, I must keep on working :(. I am a python developer, dedicated mainly to web projects. I use django, sqlite3, browsers, and ocassionaly (only if I have no choice) I install postgres, mysql, apache or any other servers commonly used in the internets. I do my coding on vim, use ssh to connect, lftp to transfer files, IRC, grep/ack... So I spend most of my time in the terminal shells. But I also use IM or Skype to communicate with my clients and peers, as well as some other software (that after all is not mandatory for my day-to-day work). I currently work with a Macbook Pro (3 years old now) and so far I am very happy with the performance. But I don't want to carry it if I am going to be "on transit" for long time, it is simply huge and heavy for what I am planning to load in my rather small backpack (while traveling, less is more, you know). So here I am reading all kind of opinions about netbooks, because at first sight this is the kind of computer I thought I had to choose. I am going to use Linux for it, Microsoft is not my cup of tea and Mac is not available for them, unless I were to buy a Macbook air, something that I won't do because if I am robbed or rain/dust/truck loaders break it I would burst in tears. I am concerned about wifi performance and connectivity, I am going to use one of those linux distros/tools to hack/test on "open" networks (if you know what I mean) in case I am not in a place with real free wifi access and I find myself in an emergency. CPU speed should be acceptable, but since I don't plan to run Photoshop or expensive IDEs, I guess most of the time I won't be overloading the machine. Apart from this, maybe (surely) I am missing other features to consider. With that said (sorry about the length) here it comes my question, raised from a deep ignorance regarding the wars betweeb betbooks vs notebooks (I assume tablet PCs are not for programming yet): If I buy a netbook will I have to throw it away after 1 month on the road and buy a notebook? Or will I be OK? Thanks! Hector Update I have received great feedback so far! I would like to insist on the fact that I will be traveling through many different countries and scenarios. I am sure that while in Japan I will be more than fine with anything related to technology, connectivity, etc. But consider that I will be, for example, on a train through Russia (transsiberian) and will cross Mongolia as well. I will stay in friends' places sometimes, but most of the time I will have to work from hostel rooms, trains, buses, beaches (hey this last one doesn't sound too bad hehe!). I think some of your answers guys seem to focus on the geek part but loose the point of this "on the road" fact. I am very aware and agree that netbooks suck compared to notebooks, but what I am trying to do here is to find a balance and discover your experiences with netbooks to see first hand if a netbook will be a fail in the mid-long term of the trip for my purposes. So I have resumed the main concepts expressed here on this small list, in no particular order: keyboard/touchpad feel: I use vim so no need of moving mouse pointers that much, unless I am browsing the web, but intensive use of keyboard screen real state: again, terminal work for most of the time battery life: I think something very important weight/size: also very important looks not worth stealing it, don't give a shit if it is lost/stolen/broken: this may depend on kind of person, your economy, etc. Also to prevent losing work, I will upload EVERYTHING to the cloud whenever I'll have a chance. wifi: don't want to discover my wifi is one of those that cannot deal with half the routers on this planet or has poor connectivity. Thanks again for your answers and comments!

  • Ubuntu 12.04 LXC nat prerouting not working

    - by petermolnar
    I have a running Debian Wheezy setup I copied exactly to an Ubuntu 12.04 ( elementary OS, used as desktop as well ) While the Debian setup runs flawlessly, the Ubuntu version dies on the prerouting to containers ( or so it seems ) In short: lxc works containers work and run connecting to container from host OK ( including mixed ports & services ) connecting to outside world from container is fine What does not work is connecting from another box to the host on a port that should be NATed to a container.

  • How to upgrade a remote server from 8.10 to newer version?

    - by DisgruntledGoat
    I have a remote server still running Ubuntu 8.10 9.04 that I can only access via SSH. If I run apt-get update I get a bunch of 404 errors on the packages. I've asked a few questions on Server Fault but got nowhere. Here's what I've done: Run apt-get update which returns errors like: Err http://gb.archive.ubuntu.com intrepid/main Packages 404 Not Found [and same for many other packages] Run do-release-upgrade which returns: Checking for a new ubuntu release Failed Upgrade tool signature Failed Upgrade tool Done downloading extracting 'jaunty.tar.gz' Failed to extract Extracting the upgrade failed. There may be a problem with the network or with the server. Edited /etc/update-manager/release-upgrades and changed from Prompt=normal to Prompt=lts (as suggested here). Running do-release-upgrade after this returns: Checking for a new ubuntu release current dist not found in meta-release file No new release found (Updated) I have followed the advice in this question and changed /etc/apt/sources.list to refer to jaunty instead of intrepid. However, that distro is not online anymore either. A comment there says I have to upgrade in chronological order... So basically, it seems like I cannot upgrade because my current distro is out of date and not supported. Is there a way to upgrade direct to 10.x or 11.x? Note, as this is a server I only have command-line access. UPDATE 24/11: I have managed to upgrade from 8.10 to 9.04. Ubuntu's EOL Upgrades page provides some alternate URLs for apt sources. I also needed to update /var/lib/update-manager/meta-release to point to the old-releases server too. However, now I cannot upgrade from 9.04 to 9.10. Running do-release-upgrade produces the same error as #2 above, except it "Failed to fetch" (the URLs in meta-release are valid). The Ubuntu Jaunty upgrade page says it's necessary to upgrade using a CD image. I followed the instructions here, but it didn't work: A fatal error occurred Please report this as a bug and include the files /var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in your report. The upgrade is now aborted. Your original sources.list was saved in /etc/apt/sources.list.distUpgrade. Traceback (most recent call last): File "/tmp/tmp.JLhTwVUugb/karmic", line 7, in sys.exit(main()) File "/tmp/tmp.JLhTwVUugb/DistUpgradeMain.py", line 132, in main if app.run(): File "/tmp/tmp.JLhTwVUugb/DistUpgradeController.py", line 1590, in run return self.fullUpgrade() File "/tmp/tmp.JLhTwVUugb/DistUpgradeController.py", line 1506, in fullUpgrade if not self.doPostInitialUpdate(): File "/tmp/tmp.JLhTwVUugb/DistUpgradeController.py", line 762, in doPostInitialUpdate self.quirks.run("PostInitialUpdate") File "/tmp/tmp.JLhTwVUugb/DistUpgradeQuirks.py", line 83, in run for plugin in self.plugin_manager.get_plugins(condition): File "/tmp/tmp.JLhTwVUugb/computerjanitor/plugin.py", line 167, in get_plugins filenames = self.get_plugin_files() File "/tmp/tmp.JLhTwVUugb/computerjanitor/plugin.py", line 120, in get_plugin_files basenames = [x for x in os.listdir(dirname) OSError: [Errno 2] No such file or directory: './plugins' It does say to report the bug, but since this is an old unsupported release I don't know if it's worth doing. However, is there a way round this, to upgrade from 9.04 to 9.10 (And then finally to 10.04 LTS.)

  • PHP-FPM stops responding and dies [migrated]

    I'm running Drupal 6 with Nginx 1.5.1 and PHP-FPM (PHP 5.3.26) on a 1GB single core VPS with 3GB of swap space on SSD storage. I just switched from shared hosting to this unmanaged VPS because my site was getting too heavy, so I'm still learning the ropes. I have moderately high traffic, I don't really monitor it closely but Google Adsense usually record close to 30K page views/day. I usually have 50 to 80 authenticated users logged in and a few hundred more anonymous users hitting the Boost static HTML cache at any given moment. The problem I'm having is that PHP-FPM frequently stops responding, resulting in Nginx 502 or 504 errors. I swear I have read every page on the internet about this issue, which seems fairly common, and I've tried endless combinations of configurations, and I can't find a good solution. After restarting Nginx and PHP-FPM, the site runs really fast for a while, and then without warning it simply stops responding. I get a white screen while the browser waits on the server, and after about 30 seconds to a minute it throws an Nginx 502 or 504 error. Sometimes it runs well for 2 minutes, sometimes 5 minutes, sometimes 5 hours, but it always ends up hanging. When I find the server in this state, there is still plenty of free memory (500MB or more) and no major CPU usage, the control and worker PHP-FPM processes are still present, and the server is still pingable and usable via SSH. A reload of PHP-FPM via the init script revives it again. The hangups don't seem to correspond to the amount of traffic, because I observed this behavior consistently when I was testing this configuration on a development VPS with no traffic at all. I've been constantly tweaking the settings, but I can't definitively eliminate the problem. I set Nginx workers to just 1. In the PHP-FPM config I have tried all three of the process managers. "Dynamic" is definitely the least reliable, consistently hanging up after only a few minutes. "Static" also has been unreliable and unpredictable. The least buggy has been "ondemand", but even that is failing me, sometimes after as much as 12 to 24 hours. But I can't leave the server unattended because PHP-FPM dies and never comes back on its own. I tried adjusting the pm.max_children value from as low as 3 to as high as 50, doesn't make a lot of difference, but I currently have it at 10. Same thing for the spare servers values. I also have set pm.max_requests anywhere from 30 to unlimited, and it doesn't seem to make a difference. According to the logs, the PHP-FPM processes are not exiting with SIGSEGV or SIGBUS, but rather with SIGTERM. I get a lot of lines like: WARNING: [pool www] child 3739, script '/var/www/drupal6/index.php' (request: "GET /index.php") execution timed out (38.739494 sec), terminating and: WARNING: [pool www] child 3738 exited on signal 15 (SIGTERM) after 50.004380 seconds from start I actually found several articles that recommend doing a graceful reload of PHP-FPM via cron every few minutes or hours to circumvent this issue. So that's what I did, "/etc/init.d/php-fpm reload" every 5 minutes. So far, it's keeping the lights on. But it feels like a dreadful hack. Is PHP-FPM really that unreliable? Is there anything else I can do? Thanks a lot!

  • How can I work efficiently on a desktop sharing workflow?

    - by OSdave
    I am a freelance Magento developer, based in Spain. One of my clients is a Germany based web development company and they're asking me something I think it's impossible. OK, maybe not impossible but definitely not a preferred way of doing things. One of their clients has a Magento Entreprise installation, which is the paid (and I think proprietary) version of Magento. Their client has forbidden them to download the files from his server. My client is asking me now to study one particular module of the application in order to interact with it from a custom module I'll have to develop. As they have a read-only ssh access to their client's server, they came up with this solution: Set up a desktop/screen sharing session between one of their developer's station and mine, alongsides with a skype conversation. Their idea is that I'll say to the developer: show me file foo.php The developer will then open this foo.php file in his IDE. I'll have then to ask him to show me the bar method, the parent class, etc... Remember that it's a read-only session, so forget about putting a Zend_Debug::log() anywhere, and don't even think about a xDebug breakpoint (they don't use any kind of debugger, sic). Their client has also forbidden them to use any version control system... My first reaction when they explained to me this was (and I actually did say it outloud to them): Well, find another client. but they took it as a joke from me. I understand that in a business point of view rejecting a client is not a good practice, but I think that the condition of this assignment make it impossible to complete. At least according to my workflow. I mean, the way I work or learn a new framework/program is: download all files and copy of db on my pc create a git repository and a branch run the application locally use breakpoints use Zend_Debug::log() write the code and tests commit to git repo upload to (test/staging first if there is one, production if not) server I have agreed to try the desktop sharing session, although I think it will be a waste of time. On one hand I don't mind, they pay me for that time, but I know me and I don't like the sensation of loosing my time. On the other hand, I have other clients for whom I can work according to my workflow. I am about to say to them that I cannot (don't want to) do it. Well, I'll first try this desktop sharing session: maybe I'm wrong and it can actually work. But I like to consider myself as a professional, and I know that I don't know everything. So I try to keep an open mind and I am always willing to learn new stuff. So my questions are: Can this desktop-sharing workflow work? What should be done in order to take the most of it? Taking into account all the obstacles (geographic locations, no local, no git), is there another way for me to work on that project?

  • git pull gives error: 401 Authorization Required while accessing https://git.foo.com/bar.git

    - by spuder
    My macbook pro is able to clone/push/pull from the company git server. My cent 6.3 vm gets a 401 error git clone https://git.acme.com/git/torque-setup "error: The requested URL returned error: 401 Authorization Required while accessing https://git.acme.com/git/torque-setup/info/refs As a work around, I've tried creating a folder, with an empty repository, then setting the remote to the company server. I get the same error when trying a git pull The remotes are identical between the machines MacBook Pro (working) git --version git version 1.7.10.2 (Apple Git-33) git remote -v origin https://git.acme.com/git/torque-setup (fetch) origin https://git.acme.com/git/torque-setup (push) Cent 6.3 (not working) yum install -y git git --version git version 1.7.1 git remote -v origin https://git.acme.com/git/torque-setup (fetch) origin https://git.acme.com/git/torque-setup (push) The git server only allows https. Not git or ssh connections. Why is the macbook pro able to do a git pull, while the cent os machine can't? Solution Update 2013-5-15 As jku mentioned, the culprit is the old version of git installed on the cent box. Unfortunately, 1.7.1 is what you get when you run yum install git The work around is to manually install a newer version of git, or simply add the username to the repo git clone https://[email protected]/git/torque-setup

  • GIT repository layout for server with multiple projects

    - by Paul Alexander
    One of the things I like about the way I have Subversion set up is that I can have a single main repository with multiple projects. When I want to work on a project I can check out just that project. Like this \main \ProductA \ProductB \Shared then svn checkout http://.../main/ProductA As a new user to git I want to explore a bit of best practice in the field before committing to a specific workflow. From what I've read so far, git stores everything in a single .git folder at the root of the project tree. So I could do one of two things. Set up a separate project for each Product. Set up a single massive project and store products in sub folders. There are dependencies between the products, so the single massive project seems appropriate. We'll be using a server where all the developers can share their code. I've already got this working over SSH & HTTP and that part I love. However, the repositories in SVN are already many GB in size so dragging around the entire repository on each machine seems like a bad idea - especially since we're billed for excessive network bandwidth. I'd imagine that the Linux kernel project repositories are equally large so there must be a proper way of handling this with Git but I just haven't figured it out yet. Are there any guidelines or best practices for working with very large multi-project repositories?

  • Mixing NIO with IO

    - by Steffen Heil
    Hi Usually you have a single bound tcp port and several connections on these. At least there are usually more connections as bound ports. My case is different: I want to bind a lot of ports and usually have no (or at least very few) connections. So I want to use NIO to accept the incoming connections. However, I need to pass the accepted connections to the existing jsch ssh library. That requires IO sockets instead of NIO sockets, it spawns one (or two) thread(s) per connection. But that's fine for me. Now, I thought that the following lines would deliver the very same result: Socket a = serverSocketChannel.accept().socket(); Socket b = serverSocketChannel.socket().accep(); SocketChannel channel = serverSocketChannel.accpet(); channel.configureBlocking( true ); Socket c = channel.socket(); Socket d = serverSocket.accept(); However the getInputStream() and getOutputStream() functions of the returned sockets seem to work different. Only if the socket was accepted using the last call, jsch can work with it. In the first three cases, it fails (and I am sorry: I don't know why). So is there a way to convert such a socket? Regards, Steffen

  • How to deploy on a remote machine using hudson's WAS Builder Plugin?

    - by Peter Schuetze
    I have a hudson build server (Windows) that does not have Websphere installed. I created a Hudson node that I connect to via SSH. I also installed the WAS Builder Plugin to run jython scripts on the AIX machine. The job that uses the WAS Builder Plugin is tied to the AIX box. I run into errors. Does anybody know, whether that setup might work or if a different setup will work for the WAS Builder Plugin? EDIT: I get following Error Message: [test] $ cmd /c call /tmp/hudson9035964108103168395.bat FATAL: command execution failed java.io.IOException: cmd: not found at java.lang.UNIXProcess.fullPath(UNIXProcess.java:372) at java.lang.UNIXProcess.<init>(UNIXProcess.java:178) at java.lang.ProcessImpl.start(ProcessImpl.java:114) at java.lang.ProcessBuilder.start(ProcessBuilder.java:466) at hudson.Proc$LocalProc.<init>(Proc.java:149) at hudson.Proc$LocalProc.<init>(Proc.java:121) at hudson.Launcher$LocalLauncher.launch(Launcher.java:633) at hudson.Launcher$ProcStarter.start(Launcher.java:268) at hudson.Launcher$RemoteLaunchCallable.call(Launcher.java:778) at hudson.Launcher$RemoteLaunchCallable.call(Launcher.java:754) at hudson.remoting.UserRequest.perform(UserRequest.java:114) at hudson.remoting.UserRequest.perform(UserRequest.java:48) at hudson.remoting.Request$2.run(Request.java:270) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:432) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:284) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:665) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:690) at java.lang.Thread.run(Thread.java:810) Finished: FAILURE I am wondering whether that plugin can be executed on a slave, especially in my case where the master is on Windows and the slave on AIX.
