  • Linux Startup Script after Gnome Login

    - by Eric
    I have a Fedora server that I want to spawn an interactive python script after the user logs on. This script will ask the user for various types of information for configuring the system or it will search for the previous config file and show them the predefined information. Originally I was going to put this in rc.local or make it run with init.d but that messed up the boot due to how the script is spawned. So I would like this script to run as soon as the user logs in to Gnome. I've searched around quite a bit and found this answer which appears to be exactly what I want, but it isn't working the way I want it to. Below is my entry. [Desktop Entry] Name=MyScript GenericName=Script for initial configuration Comment=I really want this to work Exec=/usr/local/bin/myscript.sh Terminal=true Type=Application X-GNOME-Autostart-enabled=true Whenever I login, nothing happens. So I then did a test to modified "myscript.sh" to just echo some text to a file and it worked fine. So it appears the portion that isn't working is the script popping open a terminal and waiting for the users input. Are there any additional options I need to add to make this work? I can confirm when I run /usr/local/bin/myscript.sh from the CLI it works fine. I have also tried adding "StartupNotify=true" and still no luck. Edit @John - I tried moving my Exec= to /usr/local/bin/myscript-test and this is what myscript-test contains. #!/bin/bash xterm -e /usr/local/bin/myscript.sh Yet again, when I just run the myscript-test it works fine. However when I put that in my autostart, nothing happens. Edit 2 - I did a few more tests and it did start working but I had to remove Terminal=True before the xterm would pop. Thanks for your help.

  • Server Recovery from Denial of Service

    - by JMC
    I'm looking at a server that might be misconfigured to handle Denial of Service. The database was knocked offline after the attack, and was unable to restart itself after it failed to restart when the attack subsided. Details of the Attack: The Attacker either intentionally or unintentionally sent 1000's of search queries using the applications search query url within a couple of seconds. It looks like the server was overwhelmed and it caused the database to log this message: Server Specs: 1.5GB of dedicated memory Are there any obvious mis-configurations here that I'm missing? **mysql.log** 121118 20:28:54 mysqld_safe Number of processes running now: 0 121118 20:28:54 mysqld_safe mysqld restarted 121118 20:28:55 [Warning] option 'slow_query_log': boolean value '/var/log/mysqld.slow.log' wasn't recognized.

  • Where is '/host' declared for mount in Wubi (Ubuntu 9.10)?

    Hi! I'm using Wubi (ubuntu 9.10), and I couldn't find where '/host' mountpoint is declared for mounting. There's no entry in fstab, but it's listed in /proc/mount and mounted at boot time.

  • nginx not starting at reboot after gitlab installation

    - by Luis Masuelli
    I installed nginx (1.6) in ubuntu server (14.04). After that, I installed gitlab. I didn't realize it came with its own nginx. I uninstalled gitlab later. After installing gitlab, my first nginx began to never start at boot as a service. This means: If I hit sudo netstat -anp I don't see the corresponding entry in 0.0.0.0:80. If I hit sudo nginx -s reload and then sudo netstat -anp I see the corresponding entry I mentioned. I thought I could fixing it by doing: sudo update-rc.d nginx remove sudo update-rc.d nginx defaults After removing gitlab, but it did not help me (i.e. after reboot, nginx does not automatically start). I revised the /etc/init.d/nginx just to see that $DAEMON is still /usr/sbin/nginx. Question: What should I check to see the problem here (or: what could the problem be)? sudo nginx -s reload works with no problems at all.

  • plesk: how to configure reverse proxy rules properly?

    - by rvdb
    I'm trying to configure reverse proxy rules in vhost.conf. I have Apache-2.2.8 on Ubuntu-8.04, monitored by Plesk-10.4.4. What I'm trying to achieve is defining a reverse proxy rule that defers all traffic to -say- http://mydomain/tomcat/ to the Tomcat server running on port 8080. I have mod_rewrite and mod_proxy loaded in Apache. As far as I understand mod_proxy docs, entering following rules in /var/www/vhosts/mydomain/conf/vhost.conf should work: <Proxy *> Order deny,allow Allow from all </Proxy> ProxyRequests off RewriteRule ^/tomcat/(.*)$ http://mydomain:8080/$1 [P] Yet, I am getting a HTTP 500: internal server error when requesting above URL. (Note: I decided to use a rewrite rule in order to at least get some information logged.) I have made mod_rewrite log extensively, and find following entries in the logs [note: due to a limitation of max. 2 URLs in posts of new users, I have modified all following URLs so that they only contain 1 slash after http:. In case you're suspecting typos: this was done on purpose): 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) init rewrite engine with requested uri /tomcat/testApp/ 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (3) applying pattern '^/tomcat/(.*)$' to uri '/tomcat/testApp/' 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) rewrite '/tomcat/testApp/' - 'http:/mydomain:8080/testApp/' 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) forcing proxy-throughput with http:/mydomain:8080/testApp/ 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (1) go-ahead with proxy request proxy:http:/mydomain:8080/testApp/ [OK] This suggests that the rewrite and proxy part is processed ok; still the proxied request produces a 500 error. Yet: Addressing the testApp directly via http:/mydomain:8080/testApp does work. The same setup does work on my local computer. Is there something else (Plesk-related, perhaps?) I should configure? Many thanks for any pointers! Ron

  • esx5 debian VM vlan setup

    - by Kstro21
    i have a server with ESX5, have a switch with about 20 vlans, this is how setup the trunk port interface GigabitEthernet0/1/1 description ToOper port link-type trunk undo port trunk allow-pass vlan 1 port trunk allow-pass vlan 2 to 14 stp disable ntdp enable ndp enable bpdu enable then, i created a standar switch(sw1) using the vSphere Client, the VLAN ID is set to All (4095), i also created a VM with Debian 6, with a NIC connected to sw1, now, i want to configure this NIC for a selected group of vlans auto vlan10 iface vlan10 inet static address 11.10.1.0 netmask 255.255.255.224 mtu 1500 vlan_raw_device eth0 auto vlan14 iface vlan14 inet static address 11.10.1.65 netmask 255.255.255.248 mtu 1500 vlan_raw_device eth0 so, when i restart the network using /etc/init.d/networking restart, i got this error Reconfiguring network interfaces...SIOCSIFADDR: No such device vlan14: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device SIOCSIFBRDADDR: No such device vlan14: ERROR while getting interface flags: No such device SIOCSIFMTU: No such device vlan14: ERROR while getting interface flags: No such device Failed to bring up vlan14. done. this is just part of the error, so, my questions is: is this possible?, i mean, what i'm trying to achieve using ESX Virtual Machines, VLANS, etc is this a Debian problem? can be solved? i've read about a file named z25_persistent-net.rules in Debian but it doesn't exist in my installation. in the In the vSphere Networking for ESX5 guide, you can read: If you enter 0 or leave the option blank, the port group can see only untagged (non-VLAN) traffic. If you enter 4095, the port group can see traffic on any VLAN while leaving the VLAN tags intact. So, in theory, it should work, right? Hope you can help me up with this one Thanks

  • 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?

  • Puppet : How to override / redefine outside child class (usecase and example detailled)

    - by alex8657
    The use case i try to illustrate is when to declare some item (eq mysqld service) with a default configuration that could be included on every node (class stripdown in the example, for basenode), and still be able to override this same item in some specific class (eg mysql::server), to be included by specific nodes (eg myserver.local) I illustrated this use case with the example below, where i want to disable mysql service on all nodes, but activate it on a specific node. But of course, Puppet parsing fails because the Service[mysql] is included twice. And of course, class mysql::server bears no relation to be a child of class stripdown Is there a way to override the Service["mysql"], or mark it as the main one, or whatever ? I was thinking about the virtual items and the realize function, but it only permits apply an item multiple times, not to redefine or override. # In stripdown.pp : class stripdown { service {"mysql": enable => "false", ensure => "stopped" } } # In mysql.pp : class mysql::server { service { mysqld: enable => true, ensure => running, hasrestart => true, hasstatus => true, path => "/etc/init.d/mysql", require => Package["mysql-server"], } } # Then nodes in nodes.pp : node basenode { include stripdown } node myserver.local inherits basenode { include mysql::server` # BOOM, fails here because of Service["mysql"] redefinition }

  • Sun Power Button Won't Shut Down System

    - by user36680
    Background: We are running NIS and have NFS mounts from a Solaris 10 workstation to a Solaris 8 server. If the workstation loses its network connection for some reason, when I look at the workstation's console I see repeated messages of the form: <date> <time> <hostname> ypbind[<pid>]: NIS server not responding for domain "<domain>"; still trying. If I try to login at the console as a user, it won't work because it can't authenticate my account through NIS. Also, it won't return to a login prompt again, so I can't log in as root. If I press the power button (don't hold it in) on the workstation, I see: <date> <time> <hostname> power: WARNING: Power off requested from power button or SC, powering down the system! Shutdown started. <date> <time> Changing to init state 5 - please wait. <date> <time+2 minutes> <hostname> power: WARNING: Failed to shut down the system! And continue to see messages of the form: <date> <time> <hostname> ypbind[<pid>]: NIS server not responding for domain "<domain>"; still trying. So, the questions are How do I make NIS stop trying (because I know it will fail)? Why won't it shut down?

  • Can start-stop-daemon use environmental variables?

    - by scottburton11
    I need to daemonize a Windows app running in Wine, and create a pid in /var/run. Since it requires an X11 session to run, I need to make sure the $DISPLAY variable is set in the running user's environment. Assuming I already have a X11 session running, with a given display, here's what the start-stop-daemon line looks like in my /etc/init.d script: start-stop-daemon --start --pidfile /var/run/wine-app.pid -m -c myuser -g mygroup -k 002 --exec /home/myuser/.wine/drive_c/Program\ Files/wine-app.exe Unfortunately, my version of start-stop-daemon on Ubuntu 8.04 doesn't have the -e option to set environmental variables. I gather that you could simply set $DISPLAY before the command, like so: VAR1="Value" start-stop-daemon ... But it doesn't work. Since I'm using the -c {user} option to run as a specific user, I'm guessing there's an environment switch and VAR1 is lost. I've tried exporting DISPLAY from the running user's .profile and/or .bashrc but it doesn't work either. Is there another way to do this? Is this even possible? Am I overlooking something? Many thanks

  • How to set umask globally?

    - by DevSolar
    I am using a private user group setup, i.e. a user foo's home directory is owned by foo:foo, not foo:users. For this to work, I need to set the umask to 002 globally. After a quick grep -RIi umask /etc/*, it seemed for a moment that modifying the UMASK entry in /etc/login.defs should do the trick. It does, too -- but only for console logins. If I log in to my desktop, and open a terminal there, I still get to see the default umask 022. Same goes for files created from apps started through the menu. Apparently, the display manager (or whatever X11 component responsible) does source some different setting than a console login does, and damned if I could tell which one it is. (I tried changing the setting in /etc/init.d/rc, and no, it did not help.) How / where do I set umask globally (and for all users), so that the X11 desktop environment gets the memo as well? (The system is Linux Mint / Ubuntu, in case that changes anything...)

  • vmware player won't run on CentOS due to missing /dev/vmmon, what could be the problem?

    - by Graphics Noob
    So I've tried installing vmware player 3.1.4 and 3.1.3 and both times had the same problem, when I try to load a VM I get the error "Could not open /dev/vmmon". When I ls /dev/ I can see there is no "vmmon" device present. When I try running: sudo /etc/init.d/vmware start I get the output: Starting VMware services: VMware USB Arbitrator [ OK ] Virtual machine monitor [FAILED] Virtual machine communication interface [ OK ] VM communication interface socket family [ OK ] Blocking file system [ OK ] Virtual ethernet [FAILED] which shows that the Virtual Machine Monitor fails to load. I tried following the advice on this site and ran vmware-modconfig --console --install-all I notice during the compilation there are no errors, but at the end I get the message: Starting VMware services: VMware USB Arbitrator [ OK ] Virtual machine monitor [FAILED] Virtual machine communication interface [ OK ] VM communication interface socket family [ OK ] Blocking file system [ OK ] Virtual ethernet [ OK ] Unable to start services Out of curiousity I tried: sudo /sbin/insmod /lib/modules/2.6.18-238.9.1.el5xen/misc/vmmod.ko But got the error message: insmod: error inserting 'vmmon.ko': -1 Invalid module format I have a feeling this may be the root of the problem, but I don't know what could be causing it or how to fix it.

  • Mysqld shutting down by itself

    - by AJ Naidas
    I'm running a Wordpress Blog that gets medium-high traffic. It is hosted in an Ubuntu Server 2GB Memory 2 Core Processor 40GB SSD Disk, 3TB Transfer. The problem is that MySQL shuts down by itself after an hour or two. I had to restart mysql each and every time this happens. I checked the logs and this is what I found: 140612 6:48:14 [Warning] Using unique option prefix myisam-recover instead of myisam-recover-options is deprecated and will be removed in a future release. Please use the full name instead. 140612 6:48:14 [Note] Plugin 'FEDERATED' is disabled. 140612 6:48:14 InnoDB: The InnoDB memory heap is disabled 140612 6:48:14 InnoDB: Mutexes and rw_locks use GCC atomic builtins 140612 6:48:14 InnoDB: Compressed tables use zlib 1.2.3.4 140612 6:48:14 InnoDB: Initializing buffer pool, size = 1.4G InnoDB: mmap(1502412800 bytes) failed; errno 12 140612 6:48:14 InnoDB: Completed initialization of buffer pool 140612 6:48:14 InnoDB: Fatal error: cannot allocate memory for the buffer pool 140612 6:48:14 [ERROR] Plugin 'InnoDB' init function returned error. 140612 6:48:14 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. 140612 6:48:14 [ERROR] Unknown/unsupported storage engine: InnoDB 140612 6:48:14 [ERROR] Aborting 140612 6:48:14 [Note] /usr/sbin/mysqld: Shutdown complete judging by this line: 140612 6:48:14 InnoDB: Fatal error: cannot allocate memory for the buffer pool I suspect that this is a memory problem, but I would like to hear from the experts here before I conclude. Is this a lack of memory problem? Do you think the value of max_connections in my.cnf (currently 100) is a potential cause and needs increasing? TIA.

  • Sign multiple domains with single Domain Key (dk-filter)

    - by Lashae
    Motivation The private shopping website GILT, send periodical update emails from giltgroupe.bounce.ed10.net however all of the mails are signed with domain keys of giltgroupe.com. mailed-by giltgroupe.bounce.ed10.net signed-by giltgroupe.com My Story I couldn't manage to sign x.com with y.com 's domain key using dk-filter under Debian Lenny with postfix. If I try to init dk-filter service with following arguments: DAEMON_OPTS="$DAEMON_OPTS -d x.com,y.com -c nofws -k -i /var/dk-filter/internal_hosts -s /etc/dk-keys.conf" dk-filter service signs with domain x.com (d=x.com) If I change the daemon arg.s as following: DAEMON_OPTS="$DAEMON_OPTS -d x.com -c nofws -k -i /var/dk-filter/internal_hosts -s /etc/dk-keys.conf" then emails sent From y.com is not being signed. the dk-keys.conf file is as follows: *:/var/dk-filter/y.com/mail I managed to do same thing with DKIM, works perfect. However DK doesn't seem to work. I don't have any problem signing y.com's emails with y.com's key and x.com's emails x.com's key, which indicates there is no configuration problem. Do you have any experience/advice to make it possible to sign emails from multiple domains by a specific chosen domain?

  • rpmbuild gives seg fault

    - by Deepti Jain
    I am trying to build an rpm using the rpmbuild tool. I have source code which build binaries around 30 GB. This software for which I am making the rpm has dozens of executables. When I copy only the binaries of a single executable (Eg. init) my rpm builds successfully. But when I dump the entire build to the rpm, rpmbuild does everything but gives a seg fault in the end. Here is my spec file: # This is a sample spec file for wget %define _topdir /root/mywget %define name source %define release 1 %define version 1.12 %define _builddir /root/mywget/BUILD/glenlivet %define _buildrootdir /root/mywget/BUILDROOT %define _buildroot /root/mywget/BUILDROOT %define _sourcedir /root/mywget/SOURCES BuildRoot: %{_buildroot} Summary: GNU source License: GPL Name: %{name} Version: %{version} Release: %{release} Source: %{name}-%{version}.tar.gz Prefix: /usr Group: Development/Tools %description The GNU sample program downloads files from the Internet using the command-line. %prep %setup -q -n glenlivet %build cd %{_builddir} make all %install rm -rf %{_buildrootdir} mkdir -p %{_buildrootdir}/bin cp -p -r %{_builddir}/build/obj-x64/* %{_buildrootdir}/bin/ %files %defattr(-,root,root) /bin/* If I only copy some of the binaries (let say one utility and its dependent binaries) it works fine. But when I try to copy the entire build, I get a seg fault. I get the seg fault after rpmbuild has executed these sections: %prep %build %install rpmbuild also processes my source file.

  • No sound out of headphone port on laptop

    - by Thanatos
    I cannot get sound out of the headphone port on a laptop. Headphones are plugged in, and sound comes out of the internal speakers. Windows behaves normally (sound switches to headphones when headphones are inserted). It did work in Linux at one point, but something changed, we're just not sure what. Rebooting doesn't fix. This appears to occur whether or not PulseAudio is running. Things I've tried: Rebooting. No effect. Booting into Windows. It works properly, so probably not a hardware issue. All of alsamixer. My only controls are this: "Master" Volume bar & mutable, unmuted. Controls volume. "PCM" Volume bar only. 100%. "S/PDIF" Mutable only, currently muted, has no effect. "S/PDIF" Default PCM", Mutable only, currently unmuted, has no effect. Killing PulseAudio. No effect. (It also won't stay dead! Something appears to be restarting it, and I can't tell what, but it is annoying as fuck.) alsactl init 0, no effect. sudo rm -f /var/lib/alsa/asound.state, no effect. General system info: Ubuntu 10.04 LTS Toshiba Satellite T135D-S1324 lspci says I have: 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) 01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller Some edits: Yes, the headphones are in all the way. This works in Windows: You plug headphones in, the internal speakers stop making noise, and noise comes out the head phones. Windows says I only have two sound cards: the HDMI port (which I don't care about) and the "sound card", which it claims is a "Conexant Pebble High Definition SmartAudio" In Windows, both the internal speakers and the headphone jack show up as one soundcard, which in my experience, is typical. (This is a laptop)

  • unicorn and nginx, went wrong

    - by achempion
    I try to deploy my app via capistrano. It was done, but when I start to nginx and show my site in the browser I see 'We're sorry, but something went wrong.' It is bad. I use unicorn. See my configs https://gist.github.com/3904032 I try to start server via rails s -e prodiction and it's work!

  • nginx logrotate config

    - by TomOP
    Whats the best way to rotate nginx logfiles? In my opinion, I should create a file "nginx" in /etc/logrotate.d/ and fill it with the following code and do a /etc/init.d/syslog restart after that. This would be my config (I havn't tested it yet): /usr/local/nginx/logs/*.log { #rotate the logfile(s) daily daily # adds extension like YYYYMMDD instead of simply adding a number dateext # If log file is missing, go on to next one without issuing an error msg missingok # Save logfiles for the last 49 days rotate 49 # Old versions of log files are compressed with gzip compress # Postpone compression of the previous log file to the next rotation cycle delaycompress # Do not rotate the log if it is empty notifempty # create mode owner group create 644 nginx nginx #after logfile is rotated and nginx.pid exists, send the USR1 signal postrotate [ ! -f /usr/local/nginx/logs/nginx.pid ] || kill -USR1 `cat /usr/local/nginx/logs/nginx.pid` endscript } I have both the access.log and error.log files in /usr/local/nginx/logs/ and want to rotate both daily. Can anyone please tell me if "dateext" is correct? I want the log filename to be something like "access.log-2010-12-04". One more thing: Can I do the log rotation every day on a specific time (e.g. 11 pm)? If so, how? Thanks.

  • Massive number of context switches on ksoftirqd

    - by Pace
    We have two servers that are grinding to a halt. One is a VM and the other is bare metal. Neither of them are running similar code but they are on the same network. It appears that an incredible number of context switches are arising from ksoftirqd (which is taking up a lot of CPU). vmstat output procs -----------memory---------- ---swap-- -----io---- -system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 1 0 0 605092 182496 2637556 0 0 0 0 4177 519187 8 19 73 0 0 2 0 0 605092 182496 2637556 0 0 0 0 4792 520980 8 19 74 0 0 3 0 0 605092 182496 2637552 0 0 0 0 2137 659640 18 26 56 0 0 ... pidstat output TCK4-BM-06A:~ # pidstat -w -I 5 Linux 2.6.32.12-0.7-default (TCK4-BM-06A) 07/02/2012 _x86_64_ 03:03:01 PM PID cswch/s nvcswch/s Command 03:03:06 PM 1 0.20 0.00 init 03:03:06 PM 4 386666.27 0.00 ksoftirqd/0 03:03:06 PM 6 0.60 0.00 ksoftirqd/1 03:03:06 PM 8 378213.17 0.00 ksoftirqd/2 03:03:06 PM 10 0.20 0.00 ksoftirqd/3 03:03:06 PM 12 0.20 0.00 ksoftirqd/4 03:03:06 PM 26 377115.37 0.00 ksoftirqd/11 03:03:06 PM 27 1.80 0.00 events/0 03:03:06 PM 28 1.00 0.00 events/1 03:03:06 PM 29 1.00 0.00 events/2 03:03:06 PM 30 1.00 0.00 events/3 03:03:06 PM 31 0.80 0.00 events/4 03:03:06 PM 32 0.80 0.00 events/5 ...

  • Decrease in disk performance after partitioning and encryption, is this much of a drop normal?

    - by Biohazard
    I have a server that I only have remote access to. Earlier in the week I repartitioned the 2 disk raid as follows: Filesystem Size Used Avail Use% Mounted on /dev/mapper/sda1_crypt 363G 1.8G 343G 1% / tmpfs 2.0G 0 2.0G 0% /lib/init/rw udev 2.0G 140K 2.0G 1% /dev tmpfs 2.0G 0 2.0G 0% /dev/shm /dev/sda5 461M 26M 412M 6% /boot /dev/sda7 179G 8.6G 162G 6% /data The raid consists of 2 x 300gb SAS 15k disks. Prior to the changes I made, it was being used as a single unencrypted root parition and hdparm -t /dev/sda was giving readings around 240mb/s, which I still get if I do it now: /dev/sda: Timing buffered disk reads: 730 MB in 3.00 seconds = 243.06 MB/sec Since the repartition and encryption, I get the following on the separate partitions: Unencrypted /dev/sda7: /dev/sda7: Timing buffered disk reads: 540 MB in 3.00 seconds = 179.78 MB/sec Unencrypted /dev/sda5: /dev/sda5: Timing buffered disk reads: 476 MB in 2.55 seconds = 186.86 MB/sec Encrypted /dev/mapper/sda1_crypt: /dev/mapper/sda1_crypt: Timing buffered disk reads: 150 MB in 3.03 seconds = 49.54 MB/sec I expected a drop in performance on the encrypted partition, but not that much, but I didn't expect I would get a drop in performance on the other partitions at all. The other hardware in the server is: 2 x Quad Core Intel(R) Xeon(R) CPU E5405 @ 2.00GHz and 4gb RAM $ cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 32 Lun: 00 Vendor: DP Model: BACKPLANE Rev: 1.05 Type: Enclosure ANSI SCSI revision: 05 Host: scsi0 Channel: 02 Id: 00 Lun: 00 Vendor: DELL Model: PERC 6/i Rev: 1.11 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: HL-DT-ST Model: CD-ROM GCR-8240N Rev: 1.10 Type: CD-ROM ANSI SCSI revision: 05 I'm guessing this means the server has a PERC 6/i RAID controller? The encryption was done with default settings during debian 6 installation. I can't recall the exact specifics and am not sure how I go about finding them? Thanks

  • Why does apache httpd tell me that my name-based virtualhosts only works with SNI enabled browers (RFC 4366)

    - by Arlukin
    Why does apache give me this error message in my logs? Is it a false positive? [warn] Init: Name-based SSL virtual hosts only work for clients with TLS server name indication support (RFC 4366) I have recently upgraded from Centos 5.7 to 6.3, and by that to a newer httpd version. I have always made my ssl virtualhost configurations like below. Where all domains that share the same certificate (mostly/always wildcard certs) share the same ip. But never got this error message before (or have I, maybe I haven't looked to enough in my logs?) From what I have learned this should work without SNI (Server Name Indication) Here is relevant parts of my httpd.conf file. Without this VirtualHost I don't get the error message.
