  • FreeNX Server w/ nxagent 3.5 not able to create shadow sessions

    - by Jenna Whitehouse
    I am running a FreeNX server on Ubuntu 11.10 and am unable to do session shadowing. I get the authorization prompt, but the shadow client crashes after. The NX server log in the user's .nx directory is as follows: Error: Aborting session with 'Server is already active for display 3000 If this server is no longer running, remove /tmp/.X3000-lock and start again'. Session: Aborting session at 'Mon Oct 1 14:26:44 2012'. Session: Session aborted at 'Mon Oct 1 14:26:44 2012'. This then deletes the lock file, which is the lock file for the initial Unix session and crashes out. Everything works for a normal session, and shadowing works up to the authorization prompt. I am using this software: Ubuntu 11.10 freenx-server 0.7.3.zgit.120322.977c28d-0~ppa11 nx-common 0.7.3.zgit.120322.977c28d-0~ppa11 nxagent 1:3.5.0-1-2-0ubuntu1ppa8 nxlibs 1:3.5.0-1-2-0ubuntu1ppa8 Any help is appreciated, thanks!

  • How to secure Firefox traffic (+DNS) through SOCKS proxy under Ubuntu 10.04?

    - by Maarx
    I'm using Ubuntu 10.04, and starting a SOCKS proxy with 'ssh -D', and setting Ubuntu to use it with "System - Preferences - Network Proxy". Firefox uses the proxy, and the proxy's IP appears when I visit a site like http://www.whatismyip.com/. My question is, is Firefox resolving DNS requests through this proxy? Is my web-browsing truly secure? (That is, until I exit the other end of the proxy. I know it's insecure after that.) (And I've verified the keys, I'm not being man-in-the-middled) (And--screw it. You know what I mean. Is it resolving DNS requests through the proxy?) I don't know how I would go about verifying such a thing for myself. Using additional hardware such as another debugging proxy is not an option. If Firefox isn't resolving my DNS requests through the SOCKS proxy, how do I go about fixing it?

  • How does Kerberos work with SSH?

    - by Phil
    Suppose I have four computers, Laptop, Server1, Server2, Kerberos server: I log in using PuTTY or SSH from L to S1, giving my username / password From S1 I then SSH to S2. No password is needed as Kerberos authenticates me Describe all the important SSH and KRB5 protocol exchanges: "L sends username to S1", "K sends ... to S1" etc. (This question is intended to be community-edited; please improve it for the non-expert reader.)

  • openSSL tutorial not fully working - Can sign but cannot restore original file

    - by djechelon
    I'm writing, and testing, a little tutorial for my groupmates involved in an openSSL homework. We have a bunch of PDF files, I'm the CA and each one should send me a signed PDF for me to be verified. I've told them to do the following (and tried to do it by myself) Request and obtain a certificate (I'll skip this part) Create a MIME message with the PDF file in it makemime -c "text/pdf" -a "Content-Disposition: attachment; filename=”Elaborato.pdf" Elaborato.pdf > Elaborato.pdf.msg Sign with openSSL openssl smime -sign -in Elaborato.pdf.msg -out Elaborato.pdf.p7m -certfile ca.pem -certfile nomegruppo.crt -inkey nomegruppo.key -signer nomegruppo.crt Verify with openssl smime -verify -in Elaborato.pdf.p7m -out Elaborato-verified.msg -CAfile ca.pem -signer nomegruppo.crt Extract attachment with munpack Elaborato-verified.msg View with Acrobat Reader The problem is that even if I get a file that (from its binary content) resembles a PDF file my current Ubuntu PDF viewer doesn't read it. The XXXElaborato.pdf extracted by munpack is a little bit smaller than the original. What's the problem with this procedure? In theory, they should send me the signed S/MIME message and I should be able to read the PDF within it. Why can't I restore the original content of the PDF file?

  • How to manage mounted partitions (fstab + mount points) from puppet

    - by Cristian Ciupitu
    I want to manage the mounted partitions from puppet which includes both modifying /etc/fstab and creating the directories used as mount points. The mount resource type updates fstab just fine, but using file for creating the mount points is bit tricky. For example, by default the owner of the directory is root and if the root (/) of the mounted partition has another owner, puppet will try to change it and I don't want this. I know that I can set the owner of that directory, but why should I care what's on the mounted partition? All I want to do is mount it. Is there a way to make puppet not to care about the permissions of the directory used as the mount point? This is what I'm using right now: define extra_mount_point( $device, $location = "/mnt", $fstype = "xfs", $owner = "root", $group = "root", $mode = 0755, $seltype = "public_content_t" $options = "ro,relatime,nosuid,nodev,noexec", ) { file { "${location}/${name}": ensure => directory, owner => "${owner}", group => "${group}", mode => $mode, seltype => "${seltype}", } mount { "${location}/${name}": atboot => true, ensure => mounted, device => "${device}", fstype => "${fstype}", options => "${options}", dump => 0, pass => 2, require => File["${location}/${name}"], } } extra_mount_point { "sda3": device => "/dev/sda3", fstype => "xfs", owner => "ciupicri", group => "ciupicri", $options = "relatime,nosuid,nodev,noexec", } In case it matters, I'm using puppet-0.25.4-1.fc13.noarch.rpm and puppet-server-0.25.4-1.fc13.noarch.rpm.

  • placing shell script under systemd control

    - by Calvin Cheng
    Assuming I have a shell script like this:- #!/bin/sh # cherrypy_server.sh PROCESSES=10 THREADS=1 # threads per process BASE_PORT=3035 # the first port used # you need to make the PIDFILE dir and insure it has the right permissions PIDFILE="/var/run/cherrypy/myproject.pid" WORKDIR=`dirname "$0"` cd "$WORKDIR" cp_start_proc() { N=$1 P=$(( $BASE_PORT + $N - 1 )) ./manage.py runcpserver daemonize=1 port=$P pidfile="$PIDFILE-$N" threads=$THREADS request_queue_size=0 verbose=0 } cp_start() { for N in `seq 1 $PROCESSES`; do cp_start_proc $N done } cp_stop_proc() { N=$1 #[ -f "$PIDFILE-$N" ] && kill `cat "$PIDFILE-$N"` [ -f "$PIDFILE-$N" ] && ./manage.py runcpserver pidfile="$PIDFILE-$N" stop rm -f "$PIDFILE-$N" } cp_stop() { for N in `seq 1 $PROCESSES`; do cp_stop_proc $N done } cp_restart_proc() { N=$1 cp_stop_proc $N #sleep 1 cp_start_proc $N } cp_restart() { for N in `seq 1 $PROCESSES`; do cp_restart_proc $N done } case "$1" in "start") cp_start ;; "stop") cp_stop ;; "restart") cp_restart ;; *) "$@" ;; esac From the bash script, we can essentially do 3 things: start the cherrypy server by calling ./cherrypy_server.sh start stop the cherrypy server by calling ./cherrypy_server.sh stop restart the cherrypy server by calling ./cherrypy_server.sh restart How would I place this shell script under systemd's control as a cherrypy.service file (with the obvious goal of having systemd start up the cherrypy server when a machine has been rebooted)?

  • Strange port forwarding problem

    - by rAyt
    I've got a strange port forwarding problem.

  • How do I hook into Tar with BASH?

    - by orb
    Long Story Short I am working with Tar archives that contain PNG images in base64 encoding. I would like to use BASH (or whatever else works) to hook into the extraction function of Tar to decode PNG images from base64 encoding to standard PNG encoding after the files are unpacked. A simple cat $input-file | base64 -d >$output-file will successfully decode the images. Is there a way I can hook into tar -xf so that users do not have to do any (or minimal) extra work to decode the images? In the GNU Tar documentation (http://www.gnu.org/software/tar/manual/html_chapter/Backups.html#SEC97) I found that there are in fact variables reserved to hold the names of functions I desire to be hooked into various moments in Tar program execution. However, the documentation explains that these variables, along with other variables that can be set to configure Tar, are located in a file named backup-specs. Unfortunately, the path to this file is not given. Further, running sudo find / -name backup-specs tells me that this file is not present on my Ubuntu version 13.04 system. Background Information not included in the Long Story Short I have been working on a browser-based (WebGL) particle effect creation application (http://www.particleeffect.org), (https://github.com/cgrabowski/webgl-particle-effect-editor), (https://github.com/cgrabowski/webgl-particle-effect). I have began to write a client-side-only solution for saving and loading effect data as a tar archive. However, since client-side JavaScript has limited capability to process binary data, the images used as textures in the effect are saved with base64 encoding. I have been able to implement saving effect data as a Tar archive (haven't pushed that to Github yet). However, the images present in said Tar archive cannot be manipulated unless they are decoded from base64 encoding.

  • APC File Cache not working but user cache is fine

    - by danishgoel
    I have just got a VPS (with cPanel/WHM) to test what gains i could get in my application with using apc file cache AND user cache. So firstly I got the PHP 5.3 compiled in as a DSO (apache module). Then installed APC via PECL through SSH. (First I tried with WHM Module installer, it also had the same problem, so I tried it via ssh) All seemed fine and phpinfo showed apc loaded and enabled. Then I checked with apc.php. All seemed OK But as I started testing my php application, the stats in apc for File Cache Information state: Cached Files 0 ( 0.0 Bytes) Hits 1 Misses 0 Request Rate (hits, misses) 0.00 cache requests/second Hit Rate 0.00 cache requests/second Miss Rate 0.00 cache requests/second Insert Rate 0.00 cache requests/second Cache full count 0 Which meant no PHP files were being cached, even though I had browsed through over 10 PHP files having multiple includes. So there must have been some Cached Files. But the user cache is functioning fine. User Cache Information Cached Variables 0 ( 0.0 Bytes) Hits 1000 Misses 1000 Request Rate (hits, misses) 0.84 cache requests/second Hit Rate 0.42 cache requests/second Miss Rate 0.42 cache requests/second Insert Rate 0.84 cache requests/second Cache full count 0 Its actually from an APC caching test script which tries to retrieve and store 1000 entries and gives me the times. A sort of simple benchmark. Can anyone help me here. Even though apc.cache_by_default = 1, no php files are being cached. This is my apc config Runtime Settings apc.cache_by_default 1 apc.canonicalize 1 apc.coredump_unmap 0 apc.enable_cli 0 apc.enabled 1 apc.file_md5 0 apc.file_update_protection 2 apc.filters apc.gc_ttl 3600 apc.include_once_override 0 apc.lazy_classes 0 apc.lazy_functions 0 apc.max_file_size 1M apc.mmap_file_mask apc.num_files_hint 1000 apc.preload_path apc.report_autofilter 0 apc.rfc1867 0 apc.rfc1867_freq 0 apc.rfc1867_name APC_UPLOAD_PROGRESS apc.rfc1867_prefix upload_ apc.rfc1867_ttl 3600 apc.serializer default apc.shm_segments 1 apc.shm_size 32M apc.slam_defense 1 apc.stat 1 apc.stat_ctime 0 apc.ttl 0 apc.use_request_time 1 apc.user_entries_hint 4096 apc.user_ttl 0 apc.write_lock 1 Also most php files are under 20KB, thus, apc.max_file_size = 1M is not the cause. I have also tried using 'apc_compile_file ' to force some files into opcode cache with no luck. I have also re-installed APC with Debugging enabled, but nothing shows in the error_log I have also tried setting mmap_file_mask to /dev/zero and /tmp/apc.xxxxxx, i have also set /tmp permissions to 777 to no avail Any clue anyone. Update: I have tried following things and none cause APC file cache to populate 1. set apc.enable_cli = 1 AND run a script from cli 2. Set apc.max_file_size = 5M (just in case) 3. switched php handler from dso to FastCGI in WHM (then switched it back to dso as it did not solve the problem) 4. Even tried restarting the container

  • Bridging Network Devices with Multiple IPs

    - by Andy
    I have a small server with a single NIC that I am trying to get a bridge functioning on so that I can run KVM. On this NIC I have a couple IPs statically assigned to it: eth0 = 192.168.1.1 eth0:1 = 192.168.1.2 eth0:2 = 192.168.1.3 eth0:3 -> Assign the bridge to this I am attempting to set up a bridge using the following instructions: sudo brctl addbr br0 sudo brctl addif br0 eth0:3 sudo ifconfig br0 192.168.1.120 netmask 255.255.255.0 up sudo route add -net 192.168.1.0 netmask 255.255.255.0 br0 sudo route add default gw 192.168.1.1 br0 sudo tunctl -b -u root -t tap0 > /dev/null sudo ifconfig tap0 up sudo brctl addif br0 tap0 However, when I do the second command: sudo brctl addif br0 eth0:3 It puts the ENTIRE eth0 device into promiscuous mode. This knocks the server offline and inaccessible by anything other than locally. Is there a way to bridge JUST eth0:3 to br0 and not put the entire device into promiscuous mode?

  • No architecture vs architecture-specific binaries

    From what I understand, the noarch suffix means that it's architecture independent and should work universally. If this is the case, why should I install architecture-specific packages at all? Why not just go straight for the noarch? Are there optimizations in the x86 or x64 binaries that aren't found in the noarch binaries? What's best for high performance applications?

  • Apache access.log interpretation

    - by Pantelis Sopasakis
    In the log file of apache (access.log) I find log entries like the following: 10.20.30.40 - - [18/Mar/2011:02:12:44 +0200] "GET /index.php HTTP/1.1" 404 505 "-" "Opera/9.80 (Windows NT 6.1; U; en) Presto/2.7.62 Version/11.01" Whose meaning is clear: The client with IP 10.20.30.40 applied a GET HTTP method on /index.php (that is to say http://mysite.org/index.php) receiving a status code 404 using Opera as client/browser. What I don't understand is entries like the following: 174.34.231.19 - - [18/Mar/2011:02:24:56 +0200] "GET http://www.siasatema.com HTTP/1.1" 200 469 "-" "Python-urllib/2.4" So here what I see is that someone (client with IP 174.34.231.19) accessed http://www.siasatema.com and got a 200 HTTP status code(?). It doesn't make sense to me... the only interpretation I can think of is that my apache server acts like proxy! Here are some other requests that don't have my site as destination... 187.35.50.61 - - [18/Mar/2011:01:28:20 +0200] "POST http://72.26.198.222:80/log/normal/ HTTP/1.0" 404 491 "-" "Octoshape-sua/1010120" 87.117.203.177 - - [18/Mar/2011:01:29:59 +0200] "CONNECT 64.12.244.203:80 HTTP/1.0" 405 556 "-" "-" 87.117.203.177 - - [18/Mar/2011:01:29:59 +0200] "open 64.12.244.203 80" 400 506 "-" "-" 87.117.203.177 - - [18/Mar/2011:01:30:04 +0200] "telnet 64.12.244.203 80" 400 506 "-" "-" 87.117.203.177 - - [18/Mar/2011:01:30:09 +0200] "64.12.244.203 80" 400 301 "-" "-" I believe that all these are related to some kind of attack or abuse of the server. Could someone explain to may what is going on and how to cope with this situation? Update 1: I disabled mod_proxy to make sure that I don't have an open proxy: # a2dismod proxy Where from I got the message: Module proxy already disabled I made sure that there is no file proxy.conf under $APACHE/mods-enabled. Finally, I set on my browser (Mozzila) my IP as a proxy and tried to access http://google.com. I was not redirected to google.com but instead my web page appeared. The same happened with trying to access http://a.b (!). So my server does not really work as a proxy since it does not forward the requests... But I think it would be better if somehow I could configure it to return a status code 403. Here is my apache configuration file: <VirtualHost *:80> ServerName mysite.org ServerAdmin webmaster@localhost DocumentRoot /var/www/ <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log LogLevel warn CustomLog /var/log/apache2/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 </Directory> </VirtualHost> Update 2: Using a block, I restrict the use of other methods than GET and POST... <Limit POST PUT CONNECT HEAD OPTIONS DELETE PATCH PROPFIND PROPPATCH MKCOL COPY MOVE LOCK UNLOCK> Order deny,allow Deny from all </Limit> <LimitExcept GET> Order deny,allow Deny from all </LimitExcept> Now methods other that GET are forbidden (403).

  • Memory cache Ubuntu 9.10 server x86 doesn't work as expected

    - by Matthijs
    We're using an Ubuntu 9.10 server to transfer Ghost-image files. We configured it only with Samba. And the DOS-clients connect to Samba. The latest updates are installed and so far the servers is running fine. When we image 10 pc's with the same image of 2 files of 2GB there's no disk activity. Everything is loaded in the RAM. There's 4GB in the server. But when we use 2 pc's with 2 different image files of 500 MB (8x) files then there's a lot of continuous disk activity. The speed is lower. So it seems that Ubuntu doesn't cache more then one big file. Are there settings to change this behaviour?

  • xorg DPMS off: keep VT from turning screen back on

    - by Metiu
    I have an embedded board with a small UPS. When AC power goes down, I need to turn off all power hungry devices in order to have a clean shutdown. First thing I do, is set DPMS to force powerdown, then go through the usual SIGTERM/SIGKILL/umount sequence. I have an Intel i915 Display adapter connected to an LVDS LCD panel. Unfortunately, when Xorg dies, Xserver or the VT code turn the LCD panel back on. I even tried working around it by directly poking the panel enable register in the Display chip, so that X doesn't know about it, but the panel goes back on when the VT comes back. Is there any "legal" way of keeping the display off? Thank you

  • Tomcat 7 on Ubuntu 12.04 with JRE 7 not starting

    - by Andreas Krueger
    I am running a virtual server in the web on Ubuntu 12.04 LTS / 32 Bit. After a clean install of JRE 7 and Tomcat 7, following the instructions on http://www.sysadminslife.com, I don't get Tomcat 7 up and running. > java -version java version "1.7.0_09" Java(TM) SE Runtime Environment (build 1.7.0_09-b05) Java HotSpot(TM) Client VM (build 23.5-b02, mixed mode) > /etc/init.d/tomcat start Starting Tomcat Using CATALINA_BASE: /usr/local/tomcat Using CATALINA_HOME: /usr/local/tomcat Using CATALINA_TMPDIR: /usr/local/tomcat/temp Using JRE_HOME: /usr/lib/jvm/java-7-oracle Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar > telnet localhost 8080 Trying ::1... Trying 127.0.0.1... telnet: Unable to connect to remote host: Connection refused netstat sometimes shows a Java process, most of the times not. If it does, nothing works either. Does anyone have a solution or encountered similar situations?
