• WBAdmin SystemState Problems

  - by TheD

  I recently installed DHCP on my 2008R2 Server and now Backup Exec and WBAdmin/WSB is having System State issues. Essentially, after some research, I came across a handy tool called VSHADOW which has allowed me to output all the files (and their respective directories) to a text file. And hooray, I think I found the problem: * WRITER "Dhcp Jet Writer" - WriterId = {be9ac81e-3619-421f-920f-4c6fea9e93ad} - InstanceId = {0ed0a8f4-19b0-414d-a3a8-d51d6f4ac8e0} - Supports restore events = TRUE - Writer restore conditions = VSS_WRE_IF_REPLACE_FAILS - Restore method = VSS_RME_RESTORE_AT_REBOOT - Requires reboot after restore = TRUE - Excluded files: - Component "Dhcp Jet Writer:\C:_Windows_system32_dhcp\dhcp" - Name: 'dhcp' - Logical Path: 'C:_Windows_system32_dhcp' - Full Path: '\C:_Windows_system32_dhcp\dhcp' The logical path and Full Path for DHCP is completely wrong. However I can't find where I would change this path, I assume in the registry but I've had no luck finding the key !

• Setup secure shared hosting (Apache, PHP, MySQL)

  - by Apaz

  So I'm setting up a shared hosting with Apache, PHP, MySQL and the biggest question mark is how to do with PHP, since there is a million options out there how to configure it securely. The plan is: Chroot for MySQL (built in support for chroot) Chroot for Apache (mod_security) Each user executing their PHP-scripts as their own user (see below) Set open_basedir Disable all "evil" php-functions (allow_url_fopen, system, exec, and so on) Ive looked at suexec and suphp but they seems very slow; http://blog.stuartherbert.com/php/2007/12/18/using-suexec-to-secure-a-shared-server/ http://blog.stuartherbert.com/php/2008/01/18/using-suphp-to-secure-a-shared-server/ So I've looked some more and found some other solutions: apache2-mpm-itk + mod_php(?) mod_fcgid + php-fpm mod_fastcgi + php-fpm Ive tried a simple setup with mod_fastcgi + php-fpm and it seems to work, runs as correct user and so on, but the protection against directory traveling is still open_basedir(?) One solution for that could be to use php-fpm's chroot option, but that causes a lot of other issues like domain name resolver does not work sending mail does not work Tips?

• Where is php executable on Ubuntu?

  - by user601L

  I have installed apache and php. I know php works as I have tested a simple php file on apache server. I'm writing a simple webserver which should be able to process php files. So what I want to do is once I get a request for a php file, something like 'exec php test.php' and get the output and pass it to the client. As I'm not much into Ubuntu, I don't know where is the php executable (should be in \bin right?) to do it. But there is no php file inside \bin or \usr\bin. When I run 'which php' it shows nothing. How do I do this?

• Enterprise online backup providers

  - by PHLiGHT

  We've used Iron Mountain's LiveVault service but found that it was only good for file level backups. We liked how it backed up every 15 minutes. It doesn't support Exchange 2007-10 and the web interface was very poor. Who else is everyone using? The most notable names in online backup such as Mozy and Carbonite don't really seem suitable for larger companies. We have SQL, Exchange and Sharepoint servers and are looking to virtualize in the near future. Until then bare metal restore capability would be nice. We are currently using Backup Exec 12.5 but that can be so troublesome at times. We have about 2 TB of data. 1TB is archival data.

• Modifying the initrd.img to run additional binaries in a PXE booted RHEL 6

  - by Charles Long

  I am trying to add additional automation to our existing RHEL 6 (or Oralce's implementation thereof) PXE install process by running a script in the %pre section of my kickstart config that call hpacucli, HP's raid device configuration binary. My approach has been to modify the PXE served initrd.img. I've unpacked the initrd.img and copied in the required libraries, binaries, and scripts but when the system boots using the modified initrd.img, the modified /lib (and /lib_64) are moved aside to /lib_old and /lib is linked to the /mnt/runtime/lib. How can I change this configuration so that the /lib is not moved (unlikely) or required libraries are available in the runtime /mnt/runtime/lib? To test and confirm this I've been able to get the install process to move to the 6th virtual console, which allows me to see errors, and then open a shell (a useful debugging mechanism). %pre exec /dev/tty6 2 /dev/tty6 chvt 6 /bin/sh

• SQL Server 2005: Rename DB Server Instance Name?

  - by Code Sherpa

  Hi, Can somebody tell me how to rename the DB server instance name and a DB name in SQL Server 2005? Right Now I Have SERVER/OLDNAME -- oldnameDB I want to change the server instance and also change the db name. I have tried: EXEC sp_renamedb 'oldName', 'newName' and that has changed the dbname as it appers in the tree directory. But, when I do "select @@servername" it is the old name. Also, the MDF and LDF files are still the old name. How do change instance and db names as a clean sweep across the server? Thanks.

• recommended way to collect email notifications from crond in Arch Linux

  - by nponeccop

  Arch Linux doesn't have sendmail installed by default. So I get the following messages in my syslog: Sep 15 13:16:01 zorro crond[18497]: mailing cron output for user collectors sh cronjob.sh Sep 15 13:16:01 zorro crond[18497]: unable to exec /usr/sbin/sendmail: cron output for user collectors sh cronjob.sh to /dev/null What is the recommended way to fix this default behaviour so actual messages are sent? heirloom-mailx is installed and capable of sending email messages using SMTP. Is it possible for crond to use mailx to send notifications? Is there any drop-in replacement for sendmail that sends using mailx? Sendmail is not even in the repositories.

• Shell script for replacing string in all PHP-files, for each user

  - by Mads Skjern

  Each user has some php-files using a shared database commondb. I want to iterate over all users (in users.csv), and in their home folder (e.g. /home/joe) find all php files recursively, and replace each occurrence of "commondb" with their own databasename, e.g. "joedb" for "joe". I have tried the following: #!/bin/bash # Execute like this: # bash localize.bash users.csv OLDIFS=$IFS IFS="," while read name dummy do echo $name find /home/${name} -name '*.php' -exec sed -i '' 's/commondb/${name}db/g' "{}" \; done < $1 IFS=$OLDIFS for users.csv joe, Joe J george, George G It does not fail, but the files are unchanged. I am quite weak in bash, and I can't figure out how to debug it :/ Can my script be fixed to work?

• How to let users change linux password from web browser?

  - by wag2639

  I'm not sure if this is a stackoverflow question or serverfault but here goes: I have an Ubuntu 10.04 file server (Samba/FTP/HTTP) and I would like to have the ability to give users the ability to change their password to the server using their web browser. I've written a similar script before using PHP and a mess of exec but I believe that isn't secure because it can be listened to by someone looking at the list of processes on the server. Is there some kind of plugin (PHP or Python or other) that can do this easily? I rather not use something like webmin as it's overkill for this.

• Script to gather all the files ending in .log and create a tar.gz file.

  - by Oscar Reyes

  I'm currently using this script line to find all the log files from a given directory structure and copy them to another directy where I can easily compress them. find . -name "*.log" -exec cp \{\} /tmp/allLogs/ \; The problem I have, is, the directory/subdirectory information gets lost because, I'm copying only the file. For instance I have: ./product/install/install.log ./product/execution/daily.log ./other/conf/blah.log And I end up with: /tmp/allLogs/install.log /tmp/allLogs/daily.log /tmp/allLogs/blah.log And I would like to have: /tmp/allLogs/product/install/install.log /tmp/allLogs/product/execution/daily.log /tmp/allLogs/other/conf/blah.log

• How to force rsync to use destination directory as root

  - by thepurplepixel

  I have a simple script to one-way-sync files/folders within a directory: #!/bin/bash HOST='<hostname>' USER='<username>' DIR='/downloads/' SOURCE='/srv/torrents' rsync -e "ssh -l $USER" --remove-source-files -h -4 -r --stats --progress -i $SOURCE $HOST:$DIR find $SOURCE -type d -empty -prune -exec rmdir -p \{\} \; However, when this rsync operation runs, it creates a folder, torrents in /downloads on the destination machine. How can I force rsync to put all folders & files from /srv/torrents (remote) into /downloads/ (local) instead of creating /downloads/torrents as a separate directory?

• Knife leaves stray processes on my system

  - by Leons

  I'm seeing stray knife processes on my system. I have an automated ruby script that runs bundle exec knife bootstrap against various nodes. Most of the time the knife process completes and goes away, but sometimes it stays for days. I'm noticing it days later in ps aux I think it's related to the target node being down when knife runs. The chef server timeout is high, so the action completes eventually when the node goes back up, but I think knife may give up or hang somehow during the wait. Is there something I can do about the stray knife processes? Does knife have timeout settings separate from the chef server's timeout settings?

• How to delete files quicker than rm -rf?

  - by Byakugan

  Is there any way how to delete folder/files quicker than with command rm -rf? It seems my disc is filled with bilions of files (sessions of php5) which were not deleted in cron so I need to delete them manually but it takes hours and it is still not helping reducing the amount. Thank you. My command: rm -rf /var/lib/php5/* Tried also these commands: find /var/lib/php5 -name "sess_*" -exec rm {} \; And perl -e 'chdir "/var/lib/php5/" or die; opendir D, "."; while ($n = readdir D) { unlink $n }'

• How to invoke a command using specific proxy server?

  - by Xiè Jìléi

  Some applications support proxy (http proxy or socks proxy), and some are not. For browsers, I can specify proxy server in the preferences/options dialog, and other applications may be able to configure proxy servers in config files. For general purpose, can I invoke a command using a specific proxy? Like following: $ proxy-exec --type sock5 --server 1.2.3.4:8000 -- wget/ftp ... I'm using Ubuntu Maverick. P.S. In win32, it can be implemented by hijacking the socket dlls, maybe, I'm not familiar with Linux programming, but I guess it's possible in Linux. though.

• unable to properly execute binaries from PHP

  - by Lowgain

  I was building an app on a SUSE box, and had a binary called create_group for instance, which had a suid bit and allowed my PHP app to call exec('create group grpname'); and create a new group (there are others for users, etc). The binary was a small c script that calls setuid(0) and then runs the user creation stuff. This worked perfectly on the SUSE box I recently moved my project to Ubuntu and everything works fine except these binaries. I can run them from the shell and they work okay, but when I get the PHP app to run them it just does nothing. Is there anything Ubuntu would be doing differently that I'm missing?

• Scanning php uploads in tmp directory with clamdscan fails

  - by Nikola

  I can't seem to get this thing to work, some permission problem maybe, but i can't even run clamdscan normally form console with root the result is always Permission denied. for example i create a file test.txt (eicar file) in /tmp and execute "clandscan /tmp/test.txt" in console logged in as root and i get "/tmp/test.txt: Access denied. ERROR ". The clamd demon is running with user clamav could that be the reason? Now i want to scan the same file (/tmp/test.txt) via php , so i run (i have chowned the file to apache:apache ) $cmd="clamdscan /tmp/test.txt"; exec($cmd,$a,$b); i get error 127 i try with the full path of the command /usr/bin/clamdscan i get error 126 (command is found but is not executable), this means that apache doesn't have the permission to execute /usr/bin/clamdscan ? what could be the problem?

• Backing up Windows 2003 Server that has Certificate Authority

  - by Dina

  I want to export and migrate a Certificate Authority CA role from a Windows 2003 machine to a new copy of Windows 2008 R2 virtual machine. I was told that I cannot have 2 CA roles on the same network at the same time. Therefore, I must first export the certificates on the older machine, delete the CA role, then add the CA role on the new machine and import the certificates into it. As a safety precaution, I am tasked to find a backup solution in case this does not work and I need to revert back to the old Windows 2003 CA. My question is: What is the best software for doing this type of backup? I am currently trying out Symantec Backup Exec 2012. Which I hope will allow me to create a backup prior to removing CA role on Windows 2003. If this CA migration fails, the backup will allow me to revert the old machine to a time before I removed its CA role.

• Monit send alert to nagios NSCA

  - by mYzk

  I want to monitor a web with monit check host function and if the site is down then alert it to nagios nsca so it sends the info to nagios and nagios marks it as status OK or host down for example. The problem is that how can I make the monit alert fuction send the info to nagios nsca. I am not sure that this will work, but what I came up with is: set alert exec 'echo -e "nagios nsca format" | /usr/local/nagios/bin/send_nsca -H serveraddress -c /usr/local/nagios/etc/send_nsca.cfg' Would this work and is it the best solution to work with or can it be done some other way?

• The new SSIS in SQL2005/SQL2008 are oversized

  - by Ice

  I studied the new MERGE Statement and there is a nice example for importing a flatfile. INSERT <Table> SELECT * FROM OPENROWSET BULK <Import-Flat-File>, <Format-File>... seems to be a good replacment for such a simple job and avoids to build a SSIS-Package. EXEC XP_CMDSHELL bcp <Table or View> out <Flat-File> ... is almost simpler than building an SSIS, isn't it? (I know that the MERGE-Statement doesn't run on a SQL2005)

• Syntax for piping varnish logs to rotatelogs

  - by jetboy

  Ubuntu 12.04 Server x64, Varnish 3.0.2 I'm trying to pipe varnishncsa's logs through Apache's rotatelogs, and running from the shell, things work fine: sudo varnishncsa -a -P /var/run/varnishncsa/varnishncsa.pid |/usr/sbin/rotatelogs /var/log/varnish/varnish.log.%Y%m%d%H 3600 creates a new logfile in /var/log/varnish, with rotation every hour (3600 seconds). However, I'm struggling to get things working the same way inside /etc/init.d/varnishncsa: PATH=/sbin:/bin:/usr/sbin:/usr/bin DAEMON=/usr/bin/$NAME PIDFILE=/var/run/$NAME/$NAME.pid LOGFILE=/var/log/varnish/varnishncsa.log USER=varnishlog DAEMON_OPTS="-a -P ${PIDFILE}" DAEMON_PIPE="|/usr/sbin/rotatelogs /var/log/varnish/varnish.log.%Y%m%d%H 3600" ... start_varnishncsa() { output=$(/bin/tempfile -s.varnish) log_daemon_msg "Starting $DESC" "$NAME" create_pid_directory if start-stop-daemon --start --verbose --pidfile ${PIDFILE} \ --chuid $USER --exec ${DAEMON} -- ${DAEMON_OPTS} \ > ${output} 2>&1; then log_end_msg 0 else log_end_msg 1 cat $output exit 1 fi rm $output } Where should I put DAEMON_PIPE in the above code? I've tried at the end of: if start-stop-daemon --start --verbose --pidfile ${PIDFILE} which is where additional command line parameters usually go, but it isn't creating a logfile.
