• VMware Workstation Error: Cannot find a valid peer process

  - by Robert Claypool

  I am running VMware Workstation 6.1.5 (build-126130) on CentOS 5.3 (Final). One of the guest machines is reporting an error when I try to power on the most recent snapshot. Snapshots further back in the timeline will power on without any problem. Error: Unable to change virtual machine power state: Cannot find a valid peer process to connect to. Apparently I'm not the only one with this problem. Others have been reporting it since at least early 2005. The forums say to delete unused lock files and restart any hung VMware processes (or restart the host machine), which I have done. Still no luck. Any other ideas?

• XRDP errors when trying to use sesman-x11rdp

  - by Nicholas

  I've just installed Ubuntu 11.10 Desktop on an old laptop of mine and I wanted to set it up so I could remote into it from my windows desktop. I've installed XRDP, but when I attempt to login using sesman-x11rdp it logs in, then the window shuts down. I've checked over the logs and here is what I get at the time of login: [20120123-16:49:23] [INFO ] scp thread on sck 8 started successfully [20120123-16:49:23] [INFO ] granted TS access to user nicholas [20120123-16:49:24] [INFO ] starting X11rdp session...

• Apache2 Startup warning: NameVirtualHost *:80 has no VirtualHosts

  - by Kit Roed

  When my Ubuntu Apache server (apache2) starts up I get a warning message that reads: [warn] NameVirtualHost *:80 has no VirtualHosts however, the web server is working fine... could anyone explain what I might have wrong in my site's configuration to make it give me this warning? the config file in question (located in /etc/apache2/sites-available) reads like this (details removed for brevity) <VirtualHost *> <Location /mysite> # config details here... </Location> # use the following for authorization <LocationMatch "/mysite/login"> AuthType Basic AuthName "My Site" AuthUserFile /etc/sitepasswords/passwd Require valid-user </LocationMatch> </VirtualHost> Could the fact that I'm using <Location> be a part of the problem?

• Pecl complies .so extensions for OSX built-in PHP and not MAMP

  - by Camsoft

  I've installed the sphinx binaries and libraries and am now trying to install the PECL sphinx module. My system is running OS X 10.6 with MAMP 1.8.2 installed. I try to install sphinx using the following command: sudo pecl install sphinx The PECL command outputs the following: running: phpize Configuring for: PHP Api Version: 20090626 Zend Module Api No: 20090626 Zend Extension Api No: 220090626 The versions above don't match the versions listed when doing a phpinfo(). It seems that PECL is trying to complie against the built-in version of PHP. If I ignore the errors and continue the it will successfully compile and place the sphinx.so file in: /usr/lib/php/extensions/no-debug-non-zts-20090626/sphinx.so when in fact it should be: /Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20060613/ I've tried copying the sphinx.so file to the MAMP extensions dir but when I restart apache PHP displays the following warning: PHP Startup: Unable to load dynamic library '/Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20060613/sphinx.so I think this is because MAMP is 32bit and the built-in PHP is 64bit so PECL complies for 64bit. I might be completely wrong but I did read this when I goggled on the topic. Does anyone know how to get PECL to map to the MAMP version of PHP instead of the built-in version?

• Why does ping flooding a domain name freezes and not a direct ip address

  - by CYREX

  I am wondering why, when ping flooding a domain, the ping flood freezes after a couple of seconds then continues and this freeze, unfreeze continues until i stop the ping flood. When i do the same using the ip it does not freeze. NEVER. i did for example sudo ping -f IP (It does not freeze) then i did sudo ping -f DomainName (It freezes after a couple of seconds) Why does ping flooding an IP not freezes and ping flooding the same place using the domain name does freeze. EDIT - What i mean about freezing is that the behavior of the ping flood should send a ping and create a dot (.) for each ping but also remove each dot (.) after receiving the echo request. Looks something like this: .......... <-- This means you just send 10 ping requests. If the requests are answer, for each request answer a dot is removed. The freeze happens when this is sending or receiving. The dots will stay there frozen, like is not receiving or sending any packets. For the PING FLOOD. I do not mean in the evil way of flooding a place, i mean in the testing way. To test the performance/speed of the request send and answered of the ping requests. If you send a ping flood to google's IP for about 10 seconds you would have send about 1000 packets.but if you do it to google's domain name (google.com) it will create the freeze am talking about. IMPORTANT - Do not confuse with flooding a site with ping of death attacks.

• How do I host node.js apps with pm2 without running them as root?

  - by jishi

  I have setup pm2 to run a node.js application, and I can successfully start it and it will resurrect upon reboot. However, the pm2 daemon is ran as root, which makes me think that all my node-scripts also runs as root? Even though I added them as a regular user in the system. The log files and stuff is created in the users home dir, /~/.pm2/logs, but the logs are owned by root. when I invoke pm2 startup (which handles the installation of the init.d script etc), it creates /etc/init.d/pm2-init.sh which looks like this: #!/bin/bash # chkconfig: 2345 98 02 # # description: PM2 next gen process manager for Node.js # processname: pm2 # ### BEGIN INIT INFO # Provides: pm2 # Required-Start: # Required-Stop: # Should-Start: # Should-Stop: # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: PM2 init script # Description: PM2 is the next gen process manager for Node.js ### END INIT INFO NAME=pm2 PM2=/usr/local/lib/node_modules/pm2/bin/pm2 NODE=/usr/local/bin/node export HOME="/root" start() { echo "Starting $NAME" $NODE $PM2 stopAll $NODE $PM2 resurrect } stop() { $NODE $PM2 dump $NODE $PM2 stopAll } restart() { echo "Restarting $NAME" stop start } status() { echo "Status for $NAME:" $NODE $PM2 list RETVAL=$? } case "$1" in start) start ;; stop) stop ;; status) status ;; restart) restart ;; *) echo "Usage: {start|stop|status|restart}" exit 1 ;; esac exit $RETVAL When I dump the processes (which is what it will use when resurrecting the processes), I see mentions of user "USER":"pi" but I don't think that it's actually run as user pi. Any thoughts?

• Setting up quotas on 64-bit RHEL6 OS with ext4 filesystem

  - by Rob Mangiafico

  Setting up a new 64 bit RHEL 6 server with ext4 FS. Have only worked with ext3 and 32bit RHEL5 before. No matter what I try, I cannot get it to work. Current settings for mount (from "mount" command): /dev/sda7 on / type ext4 (rw,noatime) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw,noexec,nosuid) /dev/sdb1 on /backup type ext4 (rw) /dev/sda1 on /boot type ext4 (rw,noatime) /dev/sda8 on /home type ext4 (rw,noatime,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0) /dev/sda2 on /tmp type ext4 (rw,noexec,noatime) /dev/sda6 on /usr type ext4 (rw,noatime) /dev/sda5 on /var type ext4 (rw,noatime,usrjquota=aquota.user,jqfmt=vfsv0) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) Essentially trying to get user/group quotas on /home, and user quotas on /var. Created the aquota.user and aquota.group files on /home and /var: -rw-r--r-- 1 root root 0 Nov 17 13:37 /home/aquota.group -rw-r--r-- 1 root root 0 Nov 17 13:37 /home/aquota.user -rw------- 1 root root 0 Nov 17 11:43 /var/aquota.user When I run quoatcheck I get: quotacheck -vguma quotacheck: WARNING - Quotafile /home/aquota.user was probably truncated.

• uninstall google chrome in fedora

  - by tbleckert

  Yesterday I installed Fedora 15 Beta with GNOME 3 - it works well. One problem though is that I installed Chrome 32-bit (which was wrong, should have been the 64-bit version) and now I can't uninstall it. I can't find it in Add/Remove Software, and I also can't install the correct version of Chrome because it complains about my other copy of Chrome. Any ideas how I can remove the existing copy and get the 64-bit version installed? Here's the message I get when trying to install: Test Transaction Errors: file /etc/cron.daily/google-chrome from install of google-chrome-stable-11.0.696.65-84435.x86_64 conflicts with file from package google-chrome-stable-11.0.696.65-84435.i386 file /opt/google/chrome/chrome from install of google-chrome-stable-11.0.696.65-84435.x86_64 conflicts with file from package google-chrome-stable-11.0.696.65-84435.i386 file /opt/google/chrome/chrome-sandbox from install of google-chrome-stable-11.0.696.65-84435.x86_64 conflicts with file from package google-chrome-stable-11.0.696.65-84435.i386 file /opt/google/chrome/libffmpegsumo.so from install of google-chrome-stable-11.0.696.65-84435.x86_64 conflicts with file from package google-chrome-stable-11.0.696.65-84435.i386 file /opt/google/chrome/libpdf.so from install of google-chrome-stable-11.0.696.65-84435.x86_64 conflicts with file from package google-chrome-stable-11.0.696.65-84435.i386 file /opt/google/chrome/libppGoogleNaClPluginChrome.so from install of google-chrome-stable-11.0.696.65-84435.x8...

• Accidentally deleted symlink libc.so.6 in CentOS 6.4. How to get sudo privilege to re-create it?

  - by Eric

  I accidentally deleted the symbol link /lib64/libc.so.6 - /lib64/libc-2.12.so with $ sudo rm libc.so.6 Then I can not use anything including ls command. The error appears for any command I type ls: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory I've tried $ export LD_PRELOAD=/lib64/libc-2.12.so After this I can use ls and ln ..., but still can not use sudo ln ..., sudo -E ln ..., sudo su or even su. I always get this err sudo: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory or su: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory It seems LD_PRELOAD works only for the current shell session of my account, but not for a new account like root or a new session. It's a remote server so I can not use a live CD. I now have a ssh bash session alive but can not establish new ones. I have sudo privilege, but don't have root password. So currently my problem is I need to run sudo sln -s libc-2.12.so libc.so.6 to re-create the symlink libc.so.6, but I can not run sudo without libc.so.6. How can I fix it? Thanks~

• "Stream" tar action from remote server through Putty?

  - by Pekka

  I am accessing a shared hosting account through Putty / SSH. The account is pretty full, 300 MB below its quota. I need to make a full backup of all data present on the account. Creating a bzip2 file using tar cjf archive.tar.bz2 directory/* fails because there is not enough space for the tar. Does anybody know a way to create a tar file and "stream" it to a local file on my PC? Through putty or any other SSH tool?

• Unable to delete a file using bash script

  - by user3719091

  I'm having problems removing a file in a bash script. I saw the other post with the same problem but none of those solutions solved my problem. The bash script is an OP5 surveillance check and it calls an Expect process that saves a temporary file to the local drive which the bash script reads from. Once it has read the file and checked its status I would like to remove the temporary file. I'm pretty new to scripting so my script may not be as optimal as it can be. Either way it does the job except removing the file once it's done. I will post the entire code below: #!/bin/bash #GET FLAGS while getopts H:c:w: option do case "${option}" in H) HOSTADDRESS=${OPTARG};; c) CRITICAL=${OPTARG};; w) WARNING=${OPTARG};; esac done ./expect.vpn.check.sh $HOSTADDRESS #VARIABLES VPNCount=$(grep -o '[0-9]\+' $HOSTADDRESS.op5.vpn.results) # Check if the temporary results file exists if [ -f $HOSTADDRESS.op5.vpn.results ] then # If the file exist, Print "File Found" message echo Temporary results file exist. Analyze results. else # If the file does NOT exist, print "File NOT Found" message and send message to OP5 echo Temporary results file does NOT exist. Unable to analyze. # Exit with status Critical (exit code 2) exit 2 fi if [[ "$VPNCount" > $CRITICAL ]] then # If the amount of tunnels exceeds the critical threshold, echo out a warning message and current threshold and send warning to OP5 echo "The amount of VPN tunnels exceeds the critical threshold - ($VPNCount)" # Exit with status Critical (exit code 2) exit 2 elif [[ "$VPNCount" > $WARNING ]] then # If the amount of tunnels exceeds the warning threshold, echo out a warning message and current threshold and send warning to OP5 echo "The amount of VPN tunnels exceeds the warning threshold - ($VPNCount)" # Exit with status Warning (exit code 1) exit 1 else # The amount of tunnels do not exceed the warning threshold. # Print an OK message echo OK - $VPNCount # Exit with status OK exit 0 fi #Clean up temporary files. rm -f $HOSTADDRESS.op5.vpn.results I have tried the following solutions: Create a separate variable called TempFile that specifies the file. And specify that in the rm command. I tried creating another if statement similar to the one I use to verify that file exist and then rm the filename. I tried adding the complete name of the file (no variables, just plain text of the file) I can: Remove the file using the full name in both a separate script and directly in the CLI. Is there something in my script that locks the file that prevents me from removing it? I'm not sure what to try next. Thanks in advance!

• Move smaller hard drive to partition on a larger hard drive

  - by bluejeansummer

  My parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu. I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot. Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority. In case it helps, both drives use 2.5" PATA, and I have a 1 TB external drive available if it's needed.

• awstats parse of postfix mail log drops all records

  I'm trying to get awstats to parse the postfix mail log, but it drops allmost all entries with messages like: Corrupted record (date 20091204042837 lower than 20091211065829-20000): 2009-12-04 04:28:37 root root localhost 127.0.0.1 SMTP - 1 17480 Few more are dropped with an invalid LogFormat: Corrupted record line 24 (record format does not match LogFormat parameter): 2009-11-16 04: 28:22 root root localhost 127.0.0.1 SMTP - 14755 My conf LogFormat="%time2 %email %email_r %host %host_r %method %url %code %bytesd" I believe matches the log format (and besides is the log format I've seen everywhere for awstats mail parsing). Besides, is the same entry format as all the other entries in the mail log.

• dns queries not using nscd for caching

  - by xenoterracide

  I'm trying to use nscd (Nameservices Cache Daemon) to cache dns locally so I can stop using bind to do it. I've gotten it started and ntpd seems to attempt to use it. But everything else for hosts seems to ignore it. e.g if I do dig apache.org 3 times none of them will hit the cache. I'm viewing the cache stats using nscd -g to determine whether it's been used. I've also turned the debug log level up to see if I can see it hitting and the queries don't even hit nscd. nsswitch.conf # Begin /etc/nsswitch.conf passwd: files group: files shadow: files publickey: files hosts: cache files dns networks: files protocols: files services: files ethers: files rpc: files netgroup: files # End /etc/nsswitch.confenter code here nscd.conf # # /etc/nscd.conf # # An example Name Service Cache config file.

• Repairing yum's repositories on a RHEL5.

  - by The Rook

  I am using RHEL5 and yum is missing many packages, such as apache, php, and all php libraries . I have added the rpmforge repository, but i am still missing these packages. This is an i686 machine and there might not be many i686 packages available, I think that if i force an i386 i'll have serious problems. How do I make sure I have a large number of compatible packages on a RHEL5 system? I didn't install this system, is it normal for RHEL5 to have virtually no useful packages in yum? How do RHEL5 administrators use yum without introducing conflicts with currently installed packages? Should I ditch yum and use apt? Thanks!

• Properly escaping forward slash in bash script for usage with sed

  - by user331839

  I'm trying to determine the size of the files that would be newly copied when syncing two folders by running rsync in dry mode and then summing up the sizes of the files listed in the output of rsync. Currently I'm stuck at prefixing the files by their parent folder. I found out how to prefix lines using sed and how to escape using sed, but I'm having troubles combining those two. This is how far I got: source="/my/source/folder/" target="/my/target/folder/" escaped=`echo "$source" | sed -e 's/[\/&]/\\//g'` du `rsync -ahnv $source $target | tail -n +2 | head -n -3 | sed "s/^/$escaped/"` | awk '{i+=$1} END {print i}' This is the output I get from bash -x myscript.sh + source=/my/source/folder/ + target=/my/target/folder ++ echo /my/source/folder/ ++ sed -e 's/[\/&]/\//g' + escaped=/my/source/folder/ + awk '{i+=$1} END {print i}' ++ rsync -ahnv /my/source/folder/ /my/target/folder/ ++ sed 's/^//my/source/folder//' ++ head -n -3 ++ tail -n +2 sed: -e expression #1, char 8: unknown option to `s' + du 80268 Any ideas on how to properly escape would be highly appreciated.
