• Cannot remove storage account because of lease, but I already deleted the server [closed]

  - by djechelon

  I recently created a temporary virtual server on Azure. Then I deleted it. I wanted to delete the storage account associated with it because I didn't need it any more. The problem is that the VHD file is still associated to a non-existing virtual machine!! If I try to delete the VHD from Virtual Machines\Disks I get the Delete button greyed and the table tells me it's still associated with the old VM. If I go to storage administration and try to delete the blob from vhds/ directory I get there is an active lease. I've read on Azure forums that, in these case, one should try to force releasing the lease from the blob. I followed their instructions and downloaded their script, but running it failed. The script detected that the disk is associated to a Virtual Machine and can't be deleted. The problem is that I'm 1000000% sure that I already deleted the VM. In fact, I currently only have a single VM that has its own HD and is up and running fine! What can I do to delete that storage account that is probably sucking money from my pocket?

• How do I stop postfix from handling my mail?

  - by Tatu Ulmanen

  Here's the situation: I have a domain, let's say domain.com. That domain has Google Apps for Business enabled, so all mail delivered to @domain.com will end up at Google (MX records point to Google). I have a PHP script at domain.com that I use to send mail to myself. But when the PHP script tries to send mail to [email protected], Postfix at that server decides that the recipient is a local user (because the address matches the domain Postfix itself is at), and tries to deliver the mail locally. But inevitably fails as the mailbox cannot be found. How can I instruct Postfix to not try to handle locally any emails to @domain.com and just send them forward so Google can pick them up? I have already removed $myhostname from mydestination field in Postfix's main.cf file, and I have restarted Postfix but Postfix still tries to deliver the mail locally. Here's a snip from mail.log that show the problem (addresses replaced): postfix/pickup[20643]: AF718422E5: uid=33 from=<server> postfix/cleanup[20669]: AF718422E5: message-id=<62e706bcca5a0de0bfec6baa576d88a5@server> postfix/qmgr[20642]: AF718422E5: from=<server>, size=517, nrcpt=1 (queue active) postfix/pipe[20678]: AF718422E5: to=<[email protected]>, relay=dovecot, delay=0.62, delays=0.47/0.03/0/0.13, dsn=5.1.1, status=bounced (user unknown) postfix/bounce[20680]: AF718422E5: sender non-delivery notification: 29598422E7 postfix/qmgr[20642]: AF718422E5: removed

• Apache crashes every 5min

  - by Simon

  I'm relatively new to server issues, having a site of mine that I started early in the year grow beyond my capabilities of managing it. I need help. I recently moved out of my shared hosting environment onto a dedicated virtual server from Mediatemple. Each week, I run a script that fetches data from my DB, fetches data from last.fm's API and then tweets information to Twitter. My server uses Virtuozzo and when the script runs, Apache crashes every 5min. I checked and saw that the 'kmemsize' parameter reaches its cap (its 13mb). I realise my problem. The MySQL process stays open for long while Apache needs to handle lots of incoming links (about 200 000 pageviews for that day according to my previous host's AWSTATS). Yes, I'm quite unexperienced in this, and I'm clearly killing the server with too many incoming links while it has to manage the updating of the DB. So that is the precedent: I want a few answers. 1) Why did my shared hosting environment not crash apache every 5min? It ran fine, the site only slowed a lot. Clearly, it must be the virtual container and the kmemsize limit? 2) Where do I go from here? Would a physical server (not a virtual container) encounter the same problems? I sent a support request to Mediatemple as well. I need all the help I can get.

• Managing per-user rc.d init scripts

  - by Steve Schnepp

  I want to delegate SysV init scripts to each user. Like the SysV init, each item in ${HOME}/rc.d starting with S will be launched on server start-up with the start argument. The same for the server shut-down with the one starting with K and with the stop argument. I thought about scripting it myself, but maybe there is already some kind of implementation out there1. In summary it would be a script in /etc/init.d/ that iterates through all the users and launches runparts as the user on the relevant scripts. The platform here is a Linux (Debian flavour), but I think the solution would be quite portable among various Unix-like platforms. Update: The point here is for users to be able to create their own init scripts that should be launch on their behalf when the system boots up. As Dan Carley pointed out, the services won't be able to access any system asset (priviledged ports, system logs, ...). 1. This way I don't have to think that much about all the subtle security implications such as script timeouts for example...

• django : nginx : jquery css not being served

  - by PlanetUnknown

  I'm using apache+mod_wsgi for django. And all css/js/images are served through nginx. For some odd, reason when others/friends/colleagues try accessing the site, jquery/css is not getting loaded for them, hence the page looks jumbled up. My html files use code like this - <link rel="stylesheet" type="text/css" href="http://x.x.x.x:8000/css/custom.css"/> <script type="text/javascript" src="http://1x.x.x.x:8000/js/custom.js"></script> My nginx configuration in sites-available is like this - server { listen 8000; server_name localhost; access_log /var/log/nginx/aa8000.access.log; error_log /var/log/nginx/aa8000.error.log; location / { index index.html index.htm; } location /static/ { autoindex on; root /opt/aa/webroot/; } } There is a directory /opt/aa/webroot/static/ which have corresponding css & js directories. The odd thing is that the pages show fine when I access them. I have cleared my cache/etc, but the page loads fine for me, from various browsers. Also, I don't see any 404 any error in the nginx log files. Actually the logs for nginx are not getting refreshed at all. I restarted the nginx server using root, is that incorrect ? There is a user www-data defined in the nginx configuration file. Any pointers would be great.

• Problem restoring from tar backup: why are there /dev/disk/by-id/ symlinks and how can I avoid them?

  - by SK.

  Hello, I'm trying to make a bare-bone backup system with the most basic tools available on openSUSE 11.3 (in this case: bash, fdisk, tar & grub legacy) Here's the workflow for my scripts: backup.sh: (Run from external system, e.g. LiveCD) make an fdisk script ($fscript) from fdisk -l's output [works] mount the partitions from the system's fstab [works] tar the crucial stuff in file.tgz [works] restore.sh: (Run from external system, e.g. LiveCD) run fdisk $dest < $fscript to restore partitioning [works] format and mount partitions from system's fstab [fails] extract from file.tgz [works when mounting manually] restore grub [fails] I have recently noticed that openSUSE (though I'm sure it has nothing to do with the distro) has different output in /etc/fstab and /boot/grub/menu.lst, more precisely the partition name is for example "/dev/disk/by-id/numbers-brandname-morenumbers-part2" instead of "/dev/sda2" -- but it basically is a simple symlink. My questions about this: what is the point of such symlinks, especially if we're restoring on a different disk? is there a way to cleanly prevent the creation of those symlinks and use the "true" /dev/sdx everywhere instead? if the previous is no, do you know a way to replace those symlinks on the fly in a text file? I tried this script but only works if the file starts with the symlink description (case of fstab, not menu.lst): ### search and replace /dev/disk/by-id/... to /dev/sdx while read oldVolume rest; do # get first element, ignore rest of line if [[ "$oldVolume" =~ ^/dev/disk/by-id/.*(-part[0-9]*$)? ]]; then newVolume=$(readlink $oldVolume) # replace pointer by pointee, returns "../../sdx" echo /dev/${newVolume##*/} $rest >> TMP # format to "/dev/sdx", write line else echo $oldVolume $rest >> TMP # nothing to do fi done < $file mv -f TMP $file # save changes I've had trouble finding a solution to this on google so I was hoping some of the members here could help me. Thank you.

• WMI Sensors monitoring

• starting oracle database automatically.

  I am using Fedora 8 and Oracle 10g Express Edition. Every time I start my fedora I have to click on start database.

• Add folder name to beginning of filename

  - by shekhar

  I have a directory structure as below: Folder > SubFolder1 > FileName1.abc > Filename2.abc > ............. > SubFolder2 > FileName11.abc > Filename12.abc > .............. > .......... etc. I want to rename the files inside the subfolders as: SubFolder1_Filename1.abc SubFolder1_Filename2.abc SubFolder2_Filename11.abc SubFolder2_Filename12.abc i.e. add the folder name at the beginning of the file name with the delimiter "_". The directory structure should remain unchanged. Note: Beginning of file name is same. e.g. in above case File*. I made below Script for /r "PATH" %%G in (.) do ( pushd %%G for %%* in (.) do set MyDir=%%~n* FOR %%v IN (File*.*) DO REN %%v "%MyDir%_%%v" popd ) Problem with the above script is that it is taking only one Subfolder name and placing it to the beginning of file name irrespective of the folder.

• How do I ensure a process is running, even if it kills itself? (it needs to be restarted then)

  - by le_me

  I'm using linux. I want a process (an irc bot) to run every time I start the computer. But I've got a problem: The network is bad and it disconnects often, so I need to manually restart the bot a few times a day. How do I automate that? Additional information: The bot creates a pid file, called bot.pid The bot reconnects itself, but only a few times. The network is too bad, so the bot kills itself sometimes because it gets no response. What I do currently (aka my approach ;) ) I have a cron job executing startbot.rb every 5 minutes. (The script itself is in the same directory as the bot) The script: #!/usr/bin/ruby require 'fileutils' if File.exists?(File.expand_path('tmp/bot.pid')) @pid = File.read(File.expand_path('tmp/bot.pid')).chomp!.to_i begin raise "ouch" if Process.kill(0, @pid) != 1 rescue puts "Removing abandoned pid file" FileUtils.rm(File.expand_path('tmp/bot.pid')) puts "Starting the bot!" Kernel.exec(File.expand_path('./bot.rb')) else puts "Bot up and running!" end else puts "Starting the bot!" Kernel.exec(File.expand_path('./bot.rb')) end What this does: It checks if the pid file exists, if that's true it checks if kill -s 0 BOT_PID == 1 (if the bot's running) and starts the bot if one of the two checks fail/are not true. My approach seems to be quite dirty so how do I do it better?

• Windows 7 - system error 5 problem

  - by ianhobson

  My wife has just had a new computer for Christmas (with an upgrade from VISTA to Windows 7), and has joined the home network. We are using a mix of WindowsXP and Ubuntu boxes linked via a switch. We are all in the same workgroup. (No domain). Internet access, DHCP, and DNS server is an SME server that thinks it is domain controller (although we are not using a domain). I need to run a script to back up my wife's machine (venus). In the past the script creates a share on a machine with lots of space (leda), and then executes the line. PSEXEC \\venus -u admin -p adminpassword -c -f d:\Progs\snapshot.exe C: \\leda\Venus\C-drive.SNA With the wife's old XP machine, this would run the sysinternals utility, copy shapshot,exe to her machine and run it, which would then back up her C: drive to the share on leda. I cannot get this to work with Windows 7, nor can I link through to the C$ share on her machine. This gives me a permissions error (system error 5). The admin account is a full admin account. And yes - I do know the password. The ordinary shares on her machine work fine! I guess I'm missing something that Microsoft have built into Windows 7 - but what? The machine is running Windows 7 business, with windows firewall, AVG anti virus, and all the crap-ware you get with a new PC removed. Thanks

• Error related to pkg-config when installing frei0r as part of another package

  - by Anentropic

  I am trying to build https://github.com/mltframework/shotcut on OS X Lion (using their script in scripts/build_shotcut.sh) and after numerous hurdles I'm stuck on this error: ./configure: line 16062: syntax error near unexpected token `OPENCV,' ./configure: line 16062: `PKG_CHECK_MODULES(OPENCV, opencv >= 1.0.0, HAVE_OPENCV=true, true)' ERROR: Unable to configure frei0r From what I already googled this means that the PKG_CHECK_MODULES macro hasn't been defined, which probably means there's something wrong with my pkg-config, which I installed via Homebrew. Sounds like the pkg.m4 file isn't found. When I brew install pkg-config I get the following warning: Warning: m4 macros were installed to "share/aclocal". Homebrew does not append "/usr/local/share/aclocal" to "/usr/share/aclocal/dirlist". If an autoconf script you use requires these m4 macros, you'll need to add this path manually. Well I've appended that line to the dirlist file and it doesn't fix the problem above. Can anyone suggest a way forward here? I have briefly tried building my own pkg-config from source but (bizarrely) when I tried to ./configure I got the following error: checking for pkg-config... no ./configure: line 13540: --exists: command not found configure: error: pkg-config and glib-2.0 not found, please set GLIB_CFLAGS and GLIB_LIBS to the correct values if building pkg-config needs pkg-config it seems like a weird catch 22 situation... I think this is probably an unnecessary sidetrack anyway.

• MySQL extension of PHP not working

  - by Víctor

  In a Debian server, and after intallation and removal of SquirrelMail (with some downgrade and upgrade of php5, mysql...) the MySQL extension of PHP has stopped working. I have php5-mysql installed, and when I try to connect to a database through php-cli, i connect successfully, but when I try to connect from a web served by Apache I cannot connect. This script, run by php5-cli: echo phpinfo(); $link = mysql_connect('localhost', 'user, 'password'); if (!$link) { die('Could not connect: ' . mysql_error()); } echo 'Connected successfully'; mysql_close($link); Prints the phpinfo, which includes "/etc/php5/cli/conf.d/mysql.ini", and also the MySQL section with all the configuration: SOCKET, LIBS... And then it prints "Connectes successfully". But when run by apache accessed by web browser, it displays the phpinfo, which includes "/etc/php5/apache2/conf.d/mysql.ini", but has the MySQL section missing, and the script dies printing "Fatal error: Call to undefined function mysql_connect()". Note that both "/etc/php5/cli/conf.d/mysql.ini" and "/etc/php5/apache2/conf.d/mysql.ini" are in fact the same configuration, because I have in debian the structure: /etc/php5/apache2 /etc/php5/cgi /etc/php5/cli /etc/php5/conf.d And both point at the same directory: /etc/php5/apache2/conf.d -> ../conf.d /etc/php5/cli -> ../conf.d Where /etc/php5/conf.d/mysql.ini consists of one line: extension=mysql.so So my question is: why is the MySQL extension for PHP not working if I have the configuration included just in the same way as in php-cli, which is working? Thanks a lot!

• Mac OS X : Open up 3 terminals, run different commands from all for each of them, to set up a develo

  - by taelor

  I'm a Ruby on Rails Web Developer and there is a lot of repetition I go through to start up my development environment. I was wondering if there is any way that I can remove some of this repetition by writing a script, or using a program (like quicksilver) or something to get my work environment going. I know how to use quicksilver to open up terminal, and I even have a saved window group to get my 3 or 4 panes open. The next thing I would love to automatically happen is getting all three to goto a certain directory, and each run different commands. One will start the local server, and in another tab, start a background process. the other would open text mate, and then start a console session, while the last one runs a svn(or git) status. Oh yah, and I would love to go ahead and open firefox, and a few tabs going to a couple of locations. Does anyone have any suggestions on how I could make all this happen in once quicksilver command, or a double click on some type of script on my Desktop?

• Windows Server 2008 R2 Finding Hidden files that are causing drive to fill up

  - by Xaxum

  What is the best way to find out what files are sucking up so much space? My Windows directory lists its size as 15 GB but when I run a powershell script against it, it shows 40 GB. It seems 40 GB is about right because if I use that 40 GB and add it to the rest of my folders on C I get the 45 GB that is in use. I checked volume shadow copy and that is disabled and there are no volume shadow files listed. My page file is limited to 3 GB. How can I find out what files are taking 25 GB of space? Final Results: We ended up disabling UAC and then the Properties showed the true file size of the Windows folder, as shown in powershell script. This allowed us to drill down to the folder that had the issues... In our case it was in C:\Windows\System32\config\systemprofile\AppData\Local\VMware\VDM there were several large dump files, these were the mysterious unknown files in WinDirStat. It turns out our nessus scan is crashing a view service for a couple seconds so it creates a large dump file. So we will try this.. https://discussions.nessus.org/thread/5212

• Juniper’s Network Connect ncsvc on Linux: “host checker failed, error 10”

  - by hfs

  I’m trying to log in to a Juniper VPN with Network Connect from a headless Linux client. I followed the instructions and used the script from http://mad-scientist.us/juniper.html. When running the script with --nogui switch the command that gets finally executed is $HOME/.juniper_networks/network_connect/ncsvc -h HOST -u USER -r REALM -f $HOME/.vpn.default.crt. I get asked for the password, a line “Connecting to…” is printed but then the programm silently stops. When adding -L 5 (most verbose logging) to the command line, these are the last messages printed to the log: dsclient.info state: kStateCacheCleaner (dsclient.cpp:280) dsclient.info --> POST /dana-na/cc/ccupdate.cgi (authenticate.cpp:162) http_connection.para Entering state_start_connection (http_connection.cpp:282) http_connection.para Entering state_continue_connection (http_connection.cpp:299) http_connection.para Entering state_ssl_connect (http_connection.cpp:468) dsssl.para SSL connect ssl=0x833e568/sd=4 connection using cipher RC4-MD5 (DSSSLSock.cpp:656) http_connection.para Returning DSHTTP_COMPLETE from state_ssl_connect (http_connection.cpp:476) DSHttp.debug state_reading_response_body - copying 0 buffered bytes (http_requester.cpp:800) DSHttp.debug state_reading_response_body - recv'd 0 bytes data (http_requester.cpp:833) dsclient.info <-- 200 (authenticate.cpp:194) dsclient.error state host checker failed, error 10 (dsclient.cpp:282) ncapp.error Failed to authenticate with IVE. Error 10 (ncsvc.cpp:197) dsncuiapi.para DsNcUiApi::~DsNcUiApi (dsncuiapi.cpp:72) What does host checker failed mean? How can I find out what it tried to check and what failed? The HostChecker Configuration Guide mentions that a $HOME/.juniper_networks/tncc.jar gets installed on Linux, but my installation contains no such file. From that I concluded that HostChecker is disabled for my VPN on Linux? Are the POST to /dana-na/cc/ccupdate.cgi and “host checker failed” connected or independent? By running the connection over a SSL proxy I found out that the POST data is status=NOTOK (Funny side note: the client of the oh-so-secure VPN does not validate the server’s SSL certificate, so is wide open to MITM attacks…). So it seems that it’s the client that closes the connection and not the server.

• How do I deliver mail for wildcard addresses to a particular user/alias/program?

  - by David M

  I need to configure sendmail so that mail delivered for wildcard addresses is accepted for delivery and then delivered to a user, alias, or directly to a script. I can rewrite the envelope/headers any number of ways, but I don't know how to accept the wildcard address when it's provided in RCPT TO: Everything I've tried so far winds up with a 550 user unknown error. So here's a specific example: I want to be able to handle any address that consists of a series of digits followed by a dot followed by a word, then pipe that to a script. If the headers get rewritten, that's OK, but I need the envelope to contain the actual Delivered-To address. Here's the sort of SMTP session I need: 220 blah.foo.com ESMTP server ready; Thu, 22 Apr 2010 20:41:08 -0700 (PDT) HELO blort.foo.com 250 blah.foo.com Hello blort.foo.com [10.1.2.3], pleased to meet you MAIL FROM: <[email protected]> 250 2.1.0 <[email protected]>... Sender ok RCPT TO: <[email protected]> 250 2.1.5 <[email protected]>... Recipient ok I tried some stuff with regex maps, but I never got past 550 user unknown.

• While loop read multiple lines from a grep

  - by Basil

  I'm writing a script in AIX 5.3 that will loop through the output of a df and check each volume against another config file. If the volume appears in the config file, it will set a flag which is needed later in the script. If my config file only has a single column and I use a for loop, this works perfectly. My problem, however, is that if I use a while read loop to populate more than one variable per line, any variables I set between the while and the done are discarded. For example, assuming the contents of /netapp/conf/ExcludeFile.conf are a bunch of lines containing two fields each: volName="myVolume" utilization=70 thresholdFlag=0 grep volName /netapp/conf/ExcludeFile.conf | while read vol threshold; do if [ $utilization -ge $threshold ] ; then thresholdFlag=1 fi done echo "$thresholdFlag" In this example, thresholdFlag will always be 0, even if the volume appears in the file and its utilization is greater than the threshold. I could have added an echo "setting thresholdFlag to 1" in there, see the echo, and it'll still echo a 0 at the end. Is there a clean way to do this? I think my while loop is being done in a subshell, and changes I make to variables in there are actually being made to local variables that are discarded after the done.

• How can I cornify a SharePoint site?

  - by Chris Farmer

  Inspired by the April 1 gravatar changes and the memory of last year's cornification of Stack Overflow, I wanted to add a cornify button to my company's SharePoint app. I just added their html snippet to a Content Editor Web Part. <a href="http://www.cornify.com" onclick="cornify_add();return false;"> <img src="http://www.cornify.com/assets/cornifycorn.gif" width="52" height="51" border="0" alt="Cornify" /> </a><script type="text/javascript" src="http://www.cornify.com/js/cornify.js"></script> The button renders all glittery and beautiful, and the magical functionality works fine in Chrome and Firefox (I'm on Windows 7) for me. But, in IE8, all the gorgeous unicorn images get added at the bottom of the page such that you can't see them unless you scroll down. Since most of our users are IE users, I fear that this just isn't going to be all that much fun. So, is there some known way to force this to work better in IE8, or is there another similarly fun site adornment utility that I could use that might behave better in a SharePoint 2007 app running in IE7/8?

• Better logging for cronjob output using /usr/bin/logger

  - by Stefan Lasiewski

  I am looking for a better way to log cronjobs. Most cronjobs tend to spam email or the console, get ignored, or create yet another logfile. In this case, I have a Nagios NSCA script which sends data to a central Nagios sever. This send_nsca script also prints a single status line to STDOUT, indicating success or failure. 0 * * * * root /usr/local/nagios/sbin/nsca_check_disk This emails the following message to root@localhost, which is then forwarded to my team of sysadmins. Spam. forwarded nsca_check_disk: 1 data packet(s) sent to host successfully. I'm looking for a log method which: Doesn't spam the messages to email or the console Don't create yet another krufty logfile which requires cleanup months or years later. Capture the log information somewhere, so it can be viewed later if desired. Works on most unixes Fits into an existing log infrastructure. Uses common syslog conventions like 'facility' Some of these are third party scripts, and don't always do logging internally. UPDATE 2010-04-30 In the process of writing this question, I think I have answered myself. So I'll answer myself "Jeopardy-style". Is there any problem with this method? The following will send any Cron output to /usr/bin//logger, which will send to syslog, with a 'tag' of 'nsca_check_disk'. Syslog handles it from there. My systems (CentOS and FreeBSD) already handle log rotation. */5 * * * * root /usr/local/nagios/sbin/nsca_check_disk 2>&1 |/usr/bin/logger -t nsca_check_disk /var/log/messages now has one additional message which says this: Apr 29, 17:40:00 192.168.6.19 nsca_check_disk: 1 data packet(s) sent to host successfully. I like /usr/bin/logger , because it works well with an existing syslog configuration and infrastructure, and is included with most Unix distros. Most *nix distributions already do logrotation, and do it well.

• Sudoers file allow sudo on specific file for active directory group

  - by tubaguy50035

  I have active directory sign in working on an Ubuntu 12.04 box. When the user signs in, I have a script that runs that needs sudo permission (since it modifies the samba config file). How would I specify this in my sudoer's file? I've tried: %DOMAIN\\AD+Programmers ALL=NOPASSWD: /usr/local/bin/createSambaShare.php I've found various resources on the internet stating that this is how it would be done, but I'm not sure that I have the first part right. What are they using as the DOMAIN? The workgroup or the realm? I use Samba + winbind for active directory integration. Here's my smb.conf: [global] security = ads netbios name = hostname realm = COMPANYNAME.COM password server = passwordserver workgroup = COMPANYNAME idmap uid = 1000-10000 idmap gid = 1000-10000 winbind separator = + winbind enum users = no winbind enum groups = no winbind use default domain = yes template homedir = /home/%D/%U template shell = /bin/bash client use spnego = yes domain master = no EDIT: The users that should have access to run that script are all part of the Programmers group which has an Active Directory Domain Services Folder of Company.com/Staff/Security Groups (not sure if that matters or not).

• .tex file remains in use by process when batch file is triggered by .Rnw Sweave processing.

  - by drknexus

  This is a pretty specialized question. I'm using the Eclipse IDE in a Windows XP environment with the StatET plug-in so I can write R code as an R/Sweave document. This produces a .tex file that is then post processed by pdflatex.exe. When I create the file as normal everything works great (except maybe my file named russfnc2.Rnw seems to result in russfnc.pdf even though pdflatex.exe on the console window correctly says that the output is being writen to russfnc2.pdf). The big problem is when I trigger a batch file from within my Rnw code. My goal here is to spawn a side process that waits for the PDF to be made and uploads it to the server. So the Rnw contains: if(file.exists("rsp.finalize.bat")) {system("rsp.finalize.bat",wait=FALSE,invisible=FALSE)} The batch file calls Rterm.exe to run a script: setwd("C:/theprojectdirectory") while(!file.exists("russfnc.pdf")) { Sys.sleep(1) } Sys.sleep(60) At the end of that script, I use a shell call to launch psftp.exe and upload the files. All of this works fine, when I use my Eclipse profile to trigger Sweave... that is unless I have that batch file at the end of the .Rnw. When it is located there, I get the error message pdflatex.exe: Permission denied: c:\thepath\thetexfile.tex. After that, the .tex file (as far as XP is concerned) is in use by another process and I have to reboot in order to delete it (and, of course, the pdf is not made). If I manually trigger the batch file after pdflatex.exe has done its things, everything works fine. How can I make this work correctly using the tools I'm familiar with vis., R and Dos-style batch files? I'm not sure if this is a SuperUser question or a StackOverflow question, so I'm starting here.

• On AWS EC2, Unable to run sudo command after modifying permissions to /usr folder

  - by Kayote

  All, We have searched quite a bit and a few of 'Eliah Kagan's' posts are great about getting access back to sudo. However, our server is on AWS EC2 & I am a complete newbie to this. We are trying to setup Cronjobs for backing up our server data. What we did: Using Putty, we created a script file: usr/share/site-db-backup/backupToS3.php, however, Ubuntu was not saving the changes we made as it reported we did not have permission as user 'Ubuntu'. Error details are: "Upload of file backupToS3.php was successful but error occurred while setting the permission &/ or timestamp. If the problem persists, turn on 'ignore permission errors' option. Permission denied. Error code: 3 Request code 9" So, we ran the command "sudo chmod -R a+rwx /usr" for granting permission to the folder 'usr'. However, now whatever sudo command is run, we get the error: "/usr/lib/sudo/sudoers.so must be only be writable by owner. fatal error, unable to load plugins." We are complete newbies to Ubuntu & EC2 so do need step by step guidance of how to get sudo back & successfully write to the Crontab script sitting in 'usr/' folder.

• Manipulating IIS7 Configuration with Powershell

  - by John Price

  I'm trying to script some IIS7 setup tasks in PowerShell using the WebAdministration module. I'm good with setting simple properties, but am having some trouble when it comes to dealing with collections of elements in the config files. As an immediate, example, I want to have application pools recycle on a given schedule, and the schedule is a collection of times. When I set this up via the IIS management console, the relevant config section looks like this: <add name="CVSupportAppPool"> <recycling> <periodicRestart memory="1024" time="00:00:00"> <schedule> <clear /> <add value="03:31:00" /> </schedule> </periodicRestart> </recycling> </add> In my script I would like to be able to accomplish the same thing, and I have the following two lines: #clear any pre-existing schedule Clear-WebConfiguration "/system.applicationHost/applicationPools/add[@name='$($appPool.Name)']/recycling/periodicRestart/schedule" #add the new schedule Add-WebConfiguration "/system.applicationHost/applicationPools/add[@name='$($appPool.Name)']/recycling/periodicRestart/schedule" -value (New-TimeSpan -h 3 -m 31) That does almost the same thing, but the resulting XML lacks the <clear/> element that is created with via the GUI, which I believe is necessary to avoid inheriting any default values. This sort of collection (with "add", "remove", and "clear" elements) seems to be fairly standard in the config files, but I can't seem to find any good documentation on how to interact with them consistently.

• New tomcat install on OSX choking on startup.

  - by baudot

  I've completed a fresh install of Tomcat6 on an OS X box that didn't have it before. It's behaved a bit strangely in other ways, but the current hang-up is that it won't start at all. In response to running startup.sh, the catalina.out log collects this error: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/catalina/startup/Bootstrap Caused by: java.lang.ClassNotFoundException: org.apache.catalina.startup.Bootstrap at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) Other bits of strangeness noticed with this installation: the .sh scripts in the bin directory had no execute permission, and had to be manually chmodded. The log folder wasn't created, causing an earlier script crash. After I manually created the log folder, the startup script made it to this new error before failing. Running other scripts in the bin folder generates similar error messages involving NoClassDefFoundError. Bootstrap.java is indeed in the right place, though Bootstrap.class isn't in the same folder. For that matter, if any of the myriad class files for tomcat should have already been generated from their .java files, I haven't seen it.
