  • Importing csv list of contacts into Exchange 2007 GAL and create Distribution Group

    - by Ken Ray
    Here's the situation: We have a list of about 1,000 contacts (Lawyers in the area our court serves) with name and email address. I've been asked to create an email distribution list that can be used to sent emails to all of the external users on that list. I've seen various articles using the Exchange Management Shell and the Import-csv command piped through a ForEach-Object to a New-MailContact to set up the contacts. However, Exchange Management Shell is rather unhelpful, and it isn't working. What I believe I need to do is: 1) Set up a new distribution group using the Exchange Management Console. Let's say this new distribution group (which appears in the list of Distribution Groups under Recipient Configuration) is called "FloridaBar". 2) Make sure I have a csv file of the information I want to import. 3) Open Exchange Management Shell, and enter the following command: Import-csv C:\filename.csv | ForEach-Object { New-MailContact -Name $."NameColumnName" -ExternalEmailAddress $."EmailAddressColumn" -org FloridaBar Now, creating 1,000+ contacts in active directory - I assume that shouldn't be an issue. Do I have the "-org" parm wrong? Do I need to spell out the complete organization unit name (my.domain.name/Users/FloridaBar)? Is there a better way of doing this? Thanks in advance Ken

  • Usage of putty in command line from Hudson

    - by kij
    Hi, I'm trying to use putty in command line from an hudson job. The command is the following one: putty -ssh -2 -P 22 USERNAME@SERVER_ADDR -pw PASS -m command.txt Where 'command.txt' is a shell script to execute in the server through SSH. If i launch this command from the Window command prompt, it works, the shell script is executed on the server machine. If i launch a build of the hudson job configured with this batch command, it doesn't work. The build is running... and running... and running.. without doing anything, and i have to stop it manually. So my question is: Is it possible to launch an external programm (i.e. putty) from an hudson job ? ps: i tried SSH plugin but... not a really good plugin (pre/post build, fail status of the commands launched not caught by hudson, etc.) Thanks in advance for your help. Best regards. kij EDIT: These are the build logs: [workspace] $ cmd /c call C:\WINDOWS\TEMP\hudson7429256014041663539.bat C:\Hudson\jobs\Artifact deployer\workspace>putty -ssh -2 -P 22 USER@SERV_ADD -pw PASS -m com.txt Le build a été annulé Finished: ABORTED And the Hudson.err.log file at the same time (after a stop): 3 juin 2010 18:27:28 hudson.model.Run run INFO: Artifact deployer #6 aborted java.lang.InterruptedException at java.lang.ProcessImpl.waitFor(Native Method) at hudson.Proc$LocalProc.join(Proc.java:179) at hudson.Launcher$ProcStarter.join(Launcher.java:278) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:83) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:58) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:19) at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:601) at hudson.model.Build$RunnerImpl.build(Build.java:174) at hudson.model.Build$RunnerImpl.doRun(Build.java:138) at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:416) at hudson.model.Run.run(Run.java:1241) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:124) My shell script only write "hello" in a "hello.txt" file on the server, and nothing is done.

  • Dedicated server automatic backup solution

    - by Luigi
    I have a dedicated Ubuntu web server in a cloud environment, and I am looking for a nice way to do automated backups. I would like to backup some directories with web apps, and all my MySql databases. As for destination: make snapshots every two hours localy, and every six hours to a remote ftp server. Also delete backup archives older than seven days(localy + ftp), and notify on any problems by email. Now to achieve some of this functionality I use cron + shell script, and http://www.mysqldumper.net/, but really that doesn't answer my needs. Mysqldumper doesn't know automaticly about new databases, and shell script does not notify on problems. It's something I have to check out from time to time, and i don't have trust for. I googled a while, and seems like most people solve this stuff with shell scripts. Is this a method you can trust? Are there any web-gui tools, I'm missing? Maybe there is a smarter startegy for doing this? I'm a little bit confused.

  • How to debug slow queries in Django+Postgres

    - by lacker
    My database queries from Django are starting to take 1-2 seconds and I'm having trouble figuring out why. Not too big a site, about 1-2 requests per second (that hit Django; static files are just served from nginx.) The thing that confuses me is, I can replicate the slowness in the Django shell using debug mode. But when I issue the exact same queries at an sql prompt they are fast. It takes about a second for a query to return, but when I check connection.queries it reports the time as under 10 ms. Here's an example (from the Django shell): >>> p = PlayerData.objects.get(uid="100000521952372") >>> a = time.time(); p.save(); print time.time() - a 1.96812295914 >>> for d in connection.queries: print d["time"] ... 0.002 0.000 0.000 How can I figure out where this extra time is being spent? I'm using Apache+mod_wsgi in daemon mode, but this happens with just the django shell as well, so I figure it is not apache-related.

  • Cannot install git-core using macports

  • Control Panel as menu includes a blank item

    - by Matthew Ferreira
    When viewed as a menu attached to the Start Menu in Windows 7 Ultimate x64, the Control Panel contains a blank item. It looks like this: This item cannot be deleted or removed. I also cannot create a shortcut to it. No error message is displayed, instead simply nothing happens. I've tried using Shell Object Editor (using Run as Administrator) to find out if there is an errant entry on the Control Panel, but many entries (almost two dozen) are blank. There are several valid entries as well. I've looked through the registry and through C:\Windows, \system32, and \SysWOW64 but have had no success. I looked at this question, but I am not using Windows XP and thus have no option to use Tweak UI's Rebuild Icons function. Please note that this is no empty entry in the Control Panel when opened normally, only when attached to the Start Menu as a menu. I have compared the list of entries on the attached menu to the normal Control Panel and other than the blank entry, they are exactly the same. Nothing is missing from one or the other. I've also compared the menu and the normal view to reference images and lists of Control Panel items and have found no irregularities. Is anyone familiar with this problem or know of a solution? I've performed virus and malware scans and found nothing. I've used CCleaner with no change. Nothing with Shell Object Editor. Nothing with Registry Editor. Certainly someone here knows how to fix this. My only guess is the many blank entries visible in Shell Object Editor, but I am reluctant to delete that many items without further analysis and guidance. I appreciate your time and consideration.

  • Scripting an 'empty' password in /etc/shadow

    - by paddy
    I've written a script to add CVS and SVN users on a Linux server (Slackware 14.0). This script creates the user if necessary, and either copies the user's SSH key from an existing shell account or generates a new SSH key. Just to be clear, the accounts are specifically for SVN or CVS. So the entry in /home/${username}/.ssh/authorized_keys begins with (using CVS as an example): command="/usr/bin/cvs server",no-port-forwarding,no-agent-forwarding,no-X11-forwarding,no-pty ssh-rsa ....etc...etc...etc... Actual shell access will never be allowed for these users - they are purely there to provide access to our source repositories via SSH. My problem is that when I add a new user, they get an empty password in /etc/shadow by default. It looks like: paddycvs:!:15679:0:99999:7::: If I leave the shadow file as is (with the !), SSH authentication fails. To enable SSH, I must first run passwd for the new user and enter something. I have two issues with doing that. First, it requires user input which I can't allow in this script. Second, it potentially allows the user to login at the physical terminal (if they have physical access, which they might, and know the secret password -- okay, so that's unlikely). The way I normally prevent users from logging in is to set their shell to /bin/false, but if I do that then SSH doesn't work either! Does anyone have a suggestion for scripting this? Should I simply use sed or something and replace the relevant line in the shadow file with a preset encrypted secret password string? Or is there a better way? Cheers =)

  • WS2008 subst in Logon script does not "stick"

    - by Frans
    I have a terminal server environment exclusively with Windows Server 2008. My problem is that I need to "map" a drive letter to each users Temp folder. This is due to a legacy app that requries a separate Temp folder for each user but which does not understand %temp%. So, just add "subst t: %temp%" to the logon script, right? The problem is that, even though the command runs, the subst doesn't "stick" and the user doesn't get a T: drive. Here is what I have tried; The simplest version: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") WinShell.Run "subst T: %temp%", 2, True That didn't work, so tried this for more debug information: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") Set procEnv = WinShell.Environment("Process") wscript.echo(procEnv("TEMP")) tempDir = procEnv("TEMP") WinShell.Run "subst T: " & tempDir, 3, True This shows me the correct temp path when the user logs in - but still no T: Drive. Decided to resort to brute force and put this in my login script: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") WinShell.Run "\\domain\sysvol\esl.hosted\scripts\tempdir.cmd", 3, True where \domain\sysvol\esl.hosted\scripts\tempdir.cmd has this content: echo on subst t: %temp% pause When I log in with the above then the command window opens up and I can see the subst command being executed correctly, with the correct path. But still no T: drive. I have tried running all of the above scripts outside of a login script and they always work perfectly - this problem only occurs when doing it from inside a login script. I found a passing reference on an MSFN forum about a similar problem when the user is already logged on to another machine - but I have this problem even without being logged on to another machine. Any suggestion on how to overcome this will be much appreciated.

  • mysqldump skip one table

    - by danneth
    I'm running a cronjob to backup our system using mysqldump. The database contains 90 or so tables. One of these tables is HUGE and every once in a while causes the dump to fail. From the manual I see that you can specify specific tables to dump shell> mysqldump [options] db_name [tbl_name ...] This got me thinking. What if I have two jobs, one for dumping the huge table, and one for all the others. To accomplish this it would be nice if I could to something like shell> mysqldump -u backupuser -p database huge_table > db_huge_table.sql shell> mysqldump -u backupuser -p database --skip huge_table > db_rest.sql Unfortenately I'm not seeing such and option. I could of course explicitly state the 90 tables, but that just seems like a mess. Another option would be a script of some sort, but before checking that route I'll try this resource. MySQL is 5.1.61 on CentOS 6.2

  • How to install Windows with no CD drive boot option in BIOS?

    - by Kris Hollenbeck
    I have a new computer which I built from scratch and I am trying to install a copy of Windows Vista on it. I am able to get to the BIOS and change the boot options which are as follows.. -Built-in EFI Shell -SATA: ST31000528AS I have searched around for and everything I find says to boot from the CD rom. However, as you can see. That is not an option for me. So I am wondering if there is another way around this? Is it possible to boot the Disk from the EFI Shell? Any help is much appreciated. Thanks EDIT: I have tried this.. http://technet.microsoft.com/en-us/library/dd744321%28v=ws.10%29.aspx UPDATE: I managed to make my USB bootable via the BIOS and I have copied my windows Vista disk onto my USB via drag and drop. However I am still not able to get the windows install to start. Also I have tried booting it from the EFI shell using the following command.. blk6: blk6:\> \EFI\BOOT\BOOTX64.EFI Still no luck..

  • Connecting SVN from Remote Server

    - by Ashish
    I have hosted my repository in assebbla & it works fine. now I want to write a script that can automate the build process : 1. Take the code from assembla repository 2. Make a dump and copy it onto my web server. what I have researched from net states that use of commands like svn co svn+ssh://[email protected]/home/svn/test I believe I need to open Shell on my server and type these commands but shell has been disabled from my server admin. I tried to run the same from php using exec , admin has disabled that too. (am using shared hosting and want to do a automated deployment using these simple steps. i don't want to bring my local system in this process) now am not sure even if I get the shell access open to my server these commands like svn will work there as I don't have SVN installed on my server (its installed on assembla). kindly let me know if any more explanation is required regarding the same or if am going on the wrong track. Am a newbie so please be descriptive in answering :) Thanx in advance Ace

  • Cannot ssh into server

    - by revolver
    I am trying to SSH into a linux machine running ubuntu, but the interactive shell stuck somewhere and I can't key in anything. I am on Mac OS X Lion. This only happens when I am trying to access via an external IP. Local LAN SSH is working perfectly. macbook:~ user$ ssh -v -v user@serverip // i skipped the rest of the log, but I can paste it here again if needed. Authenticated to serverip debug1: channel 0: new [client-session] debug2: channel 0: send open debug1: Requesting [email protected] debug1: Entering interactive session. debug2: callback start debug2: client_session2_setup: id 0 debug2: channel 0: request pty-req confirm 1 debug1: Sending environment. debug1: Sending env LC_CTYPE = UTF-8 debug2: channel 0: request env confirm 0 debug2: channel 0: request shell confirm 1 debug2: fd 3 setting TCP_NODELAY debug2: callback done debug2: channel 0: open confirm rwindow 0 rmax 32768 My terminal shell just hang after this, and I can't key in anything. I checked var/log/auth on the server and saw that the a session is being created and I had already logged in, but I don't see any responses on my client machine. I googled around and a lot of the solution had to do with the Broadcom wireless driver, but I am not even using one, so I am pretty clueless here. To give you more information, the linux machine is also running a web server, and I have no problem accessing the web server. Thanks. Any help is appreciated.

  • Preventing back connect in Cpanel servers

    - by Fernando
    We run a Cpanel server and someone gained access to almost all accounts using the following steps: 1) Gained access to an user account due to weak password. Note: this user didn't had shell access. 2) With this user account, he accessed Cpanel and added a cron task. The cron task was a perl script that connected to his IP and he was able to send back shell commands. 3) Having a non jailed shell, he was able to change content of most websites in server specially for users who set their folders to 777 ( Unfortunately a common recommendation and sometimes a requirement for some PHP softwares ). Is there a way to prevent this? We started by disabling cron in Cpanel interface, but this is not enough. I see a lot of other options in which an user could run this perl script. We have a firewall running and blocking uncommon outgoing ports. But he used port 80 and, well, I can't block this port as a lot of processes use them to access things, even Cpanel itself.

  • running a command line app with sudo and password automatically on start up OS X (Lion)

    - by Designer023
    I need to run an app at startup/login on my mac. I want it to launch in the background and start doing it's work without interrupting me or me having to start it up because I invariably forget and then when I need it, it wasn't running! I have tried using applescript to tell terminal to run it and type my password in, but it ends up opening multiple Terminal windows and not working. Ideally I need a script that I can just add to the user login items and it will run for me. The app has no way of taking a password argument either and it has a password as well as the sudo! I need a solution that can either be done as an applescript (which can be made into an executable) or i need a commandline script but I have no idea about them. This is the manual code I type >sudo serverStatus >password:123456 >password:serverpass Not sure if this is the right stack to ask, but I have no idea now and it's above my head! Thanks :D My applescript: tell application Terminal activate do shell script "sudo serverStatus" delay 5 do shell script "123456" delay 2 do shell script "serverpass" end tell

  • How to securely control access to a backend key server?

    - by andy
    I need to securely encrypt data in my database so that if the database is dumped, hackers are unable to decrypt the data. I'm planning on creating a simple key server on a different machine, and allowing the DB server access to it (restricted by IP address on the key server to permit the DB server). The key server would contain the key required to encrypt/decrypt data. However, if a hacker were able to get a shell on the DB server, they could request the key from the key server and therefore decrypt the data in the database. How could I prevent this (assuming all firewalls are in place, DB is not connected directly to the internet, etc)? i.e. is there some method I could use that could secure a request from the DB server to the key server so that even if a hacker had a shell on the DB server they'd be unable to make those same requests? Signed requests from the DB server could make issuing these requests less trivial - I suppose that'd help increase the amount of time it'd take to compromise the key server, something a hacker probably wouldn't have much of. As far as I can see, if someone can get a shell on the DB server everything's lost anyway. This could be mitigated by using one key per data item in the DB so at least there's not a single "master" key, but multiple keys that the hacker would need to access. What would be a secure method of ensuring requests from the DB server to the key server were authentic and could be trusted?

  • jqGrid with JSON data renders table as empty

  • Java3D: Problem with order of objects that have a transparent PNG texture

    - by Sebastian
    Hello! Today I tried to program a little fish tank with Java 3D. The fish tank rotates and fishes are placed in it. The fishes in the box are Java 3D Boxes with a PNG picture that has an alpha channel. Without activated transparency the order of the objects is correct. But when I enable it, some fishes in the back come to the front what looks really wrong. I tried NICEST, FASTEST and BLENDED as Transparency Options but I had no effort. Does someone know what the problem could be? Vector3f[] posf = new Vector3f[5]; posf[0] = new Vector3f(-0.22f, -0.1f, -0.2f); posf[1] = new Vector3f(-0.34f, 0.1f, 0.2f); posf[2] = new Vector3f(0.3f, -0.2f, 0.3f); Appearance fischapp = new Appearance(); fischapp.setTransparencyAttributes(new TransparencyAttributes(TransparencyAttributes.NICEST, 1f)); try { fischapp.setTexture(new TextureLoader(ImageIO.read(new File("nemo.png")), this).getTexture()); } catch(IOException exc) { System.out.println(exc.getMessage()); } for(int i = 0; i Thank you!

  • Can't call animated png script from external js file

    - by Tomas
    Hello, I'm trying to put an animated PNG dinamicaly from external .js file. First I found a simple animated png solution, which draws an animation wherever you put the code within tags, but now it looks like I don't know how to call the function properly from external file. The script is from www.squaregoldfish.co.uk/software/animatedpng, and it looks something like this: <script type="text/javascript" src="animatedpng.js"></script> <div id="pnganim" align="center"> <script> fishAnim = new AnimatedPNG('fish', 't01.png', 3, 100); fishAnim.draw(false); </script> </div> Now, I'm trying to call this from external.js file and jquery: function addFish(){ $('#pnganim').html('<script type="text/javascript" src="animatedpng.js" />'); fishAnim = new AnimatedPNG('fish', 'fish01.png', 3, 100); myFish = fishAnim.draw(false); $('#pnganim').append(myFish); } ... and it's not working. After I click a button that calls the addFish function, it opens only the first frame on a blank page. What am I doing wrong here? Thanks

  • Getting unpredictable data into a tabular format

    - by Acorn
    The situation: Each page I scrape has <input> elements with a title= and a value= I don't know what is going to be on the page. I want to have all my collected data in a single table at the end, with a column for each title. So basically, I need each row of data to line up with all the others, and if a row doesn't have a certain element, then it should be blank (but there must be something there to keep the alignment). eg. First page has: {animal: cat, colour: blue, fruit: lemon, day: monday} Second page has: {animal: fish, colour: green, day: saturday} Third page has: {animal: dog, number: 10, colour: yellow, fruit: mango, day: tuesday} Then my resulting table should be: animal | number | colour | fruit | day cat | none | blue | lemon | monday fish | none | green | none | saturday dog | 10 | yellow | mango | tuesday Although it would be good to keep the order of the title value pairs, which I know dictionaries wont do. So basically, I need to generate columns from all the titles (kept in order but somehow merged together) What would be the best way of going about this without knowing all the possible titles and explicitly specifying an order for the values to be put in?

  • How can I make nested string splits?

    - by Statement
    I have what seemed at first to be a trivial problem but turned out to become something I can't figure out how to easily solve. I need to be able to store lists of items in a string. Then those items in turn can be a list, or some other value that may contain my separator character. I have two different methods that unpack the two different cases but I realized I need to encode the contained value from any separator characters used with string.Split. To illustrate the problem: string[] nested = { "mary;john;carl", "dog;cat;fish", "plainValue" } string list = string.Join(";", nested); string[] unnested = list.Split(';'); // EEK! returns 7 items, expected 3! This would produce a list "mary;john;carl;dog;cat;fish;plainValue", a value I can't split to get the three original nested strings from. Indeed, instead of the three original strings, I'd get 7 strings on split and this approach thus doesn't work at all. What I want is to allow the values in my string to be encoded so I can unpack/split the contents just the way before I packed/join them. I assume I might need to go away from string.Split and string.Join and that is perfectly fine. I might just have overlooked some useful class or method. How can I allow any string values to be packed / unpacked into lists? I prefer neat, simple solutions over bulky if possible. For the curious mind, I am making extensions for PlayerPrefs in Unity3D, and I can only work with ints, floats and strings. Thus I chose strings to be my data carrier. This is why I am making this nested list of strings.

  • Can someone recommend a good tutorial on MySQL indexes, specifically when used in an order by clause

    - by Philip Brocoum
    I could try to post and explain the exact query I'm trying to run, but I'm going by the old adage of, "give a man a fish and he'll eat for a day, teach a man to fish and he'll eat for the rest of his life." SQL optimization seems to be very query-specific, and even if you could solve this one particular query for me, I'm going to have to write many more queries in the future, and I'd like to be educated on how indexes work in general. Still, here's a quick description of my current problem. I have a query that joins three tables and runs in 0.2 seconds flat. Awesome. I add an "order by" clause and it runs in 4 minutes and 30 seconds. Sucky. I denormalize one table so there is one fewer join, add indexes everywhere, and now the query runs in... 20 minutes. What the hell? Finally, I don't use a join at all, but rather a subquery with "where id in (...) order by" and now it runs in 1.5 seconds. Pretty decent. What in God's name is going on? I feel like if I actually understood what indexes were doing I could write some really good SQL. Anybody know some good tutorials? Thanks!

  • subprocess.Popen doesn't work when args is sequence

    - by pero
    I'm having a problem with subprocess.Popen when args parameter is given as sequence. For example: import subprocess maildir = "/home/support/Maildir" This works (it prints the correct size of /home/support/Maildir dir): size = subprocess.Popen(["du -s -b " + maildir], shell=True, stdout=subprocess.PIPE).communicate()[0].split()[0] print size But, this doesn't work (try it): size = subprocess.Popen(["du", "-s -b", maildir], shell=True, stdout=subprocess.PIPE).communicate()[0].split()[0] print size What's wrong?

  • How to use make and compile as C99?

    - by djTeller
    I'm trying to compile a linux kernel module using a Makefile: obj-m += main.o all: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules clean: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean Which gives me: main.c:54: warning: ISO C90 forbids mixed declarations and code I need to switch to C99. After reading I noticed I need to add a flag -std=c99, not sure where it suppose to be added. How do I change the Makefile so it will compile as C99?

  • shellcode is truncated by \x20

    - by marcelo carvalho
    Why is my shellcode is truncated after \x20 opcode, when it is copied by string to stack on a second vulnerable program? --cmd.exe-- char shell[]= "\xc7\x44\x24\x0c\x65\x78\x65\x20" ← only this line is put in stack, though hv a enough space "\xc7\x44\x24\x08\x63\x6d\x64\x2e" "\x31\xc0" "\x89\x44\x24\x04" "\x8d\x44\x24\x08" "\x89\x04\x24" "\x8d\x05\xad\x23\x86\x7c" "\xff\xd0"; --end shell--
