  • create log for an encrypted tar

    - by magiza83
    I want to create an encrypted tar but also I want to have a log of what tar has compressed, I'm using the following command: tar -cvvf - --files-from=/root/backup.cfg | openssl des3 -salt -k backuppass | dd of=/root/tmp/back.encrypted But I need to have a log of tar's stdout. I don't know how to get it, because If I use "" in tar command openssl result is not correct. I've also checked tar manual hoping to find some option to write stdout to a file, but I have found nothing. any help? thanks & Regards.

  • log execution of certain commands on linux

    - by jlsksr
    I have to maintain a system (debian) on which several users are allowed to install programs - so I would like to log, for example, if anyone executes "apt-get install" or "apt-get purge", so I can keep track of manually installed packages.. I'm looking for a general way to achieve this; it's not just APT, but several programs/scripts etc. Any ideas? /edit a google-search with few different keywords brought up this: http://serverfault.com/questions/201221/how-to-log-every-linux-command-to-a-logserver http://stackoverflow.com/questions/15698590/how-to-capture-all-the-commands-typed-in-unix-linux-by-any-user http://sourceforge.net/projects/rootsh/

  • Server unresponsive, messages shown on console but not in log files

    - by raistlin majere
    I'm using Ubuntu Server 10.04.4, and once in a while the server hangs (once a month) and is totally unresponsive. The tty is flooded with messages like these. The problem is that these messages are not in my log files after reboot. How to log these messages so that I can analyze them later? In the current logs I can't see anything that would tell me why this is happening. I would also appreciate if anybody can tell from those messages what's going on. This server is a guest virtual machine. The host server is also Ubuntu server 10.04 with KVM/QEMU.

  • Windows XP, have to use ctrl+alt+delete to log on as local administrator

    - by wickedj
    Hey, I have a weird issue, a user was was logging into a laptop using the local admin account which was working fine. I had to create another account on the system, which was also an admin account, when this happened the 'administrator' account disappeared from the 'choose an account to login with' screen. A quick workaround is available, if the user presses ctrl+alt+delete it brings you to the screen where you can type in the username and password, so by manually typing 'administrator' it can log in. Normally this would be easily fixed, I figured the admin account had somehow been disabled from the local system, but i checked all settings and it is setup fine. The laptop is not part of a domain, so I used the management console to delete the new account and all that succeeded in doing was making the 'choose an account to log in with' screen display no accounts to choose. So far I see nothing else to fix it, the option to change the default logon screen to style where you type the username and password also seems to be missing. any ideas?

  • Log into AD account through Command Line

    - by CranialPain
    Our SBS2003 server likes to lose connection every so often. This appears to 'kick' everyone out, so that no-one can access the server or its shared folders without a log off log in. It usually brings up an error message stating that Windows 7 (on the client machines) cannot find the server, even though its ping-able. Is there a way to login through the command line so I can just write a batch file and have the users double-click it and enter their credentials instead of closing down programs and logging out/in over and over?

  • How to log Windows server share connections?

    - by sbussinger
    Can anyone make a suggestion for the best way to log connections and disconnections from Windows workstations to a Windows Server 2003 file share? We're having some issues with workstations that have a drive mapped to a server that seem to work fine for awhile and then suddenly appear to get disconnected from the server (with files open). Needless to say this causes some data corruption and error messages. It would help me to troubleshoot the problem if we could somehow monitor and log the session connections and disconnections, to attempt to correlate the connectivity issues with what actions the user is taking at the time and what the server is doing. I just haven't been able to find a way to do this. Specifically I'm talking about the same information that is displayed in the Computer Management control panel applet in the "System Tools|Shared Folders|Sessions" page. Thanks!

  • syslog log of TCP packet

    - by com
    Occasionally, I noticed a lot of following messsages in syslog Nov {datetime} hostname kernel: [8226528.586232] AIF:PRIV TCP packet: IN=eth0 OUT= MAC={mac} SRC={sourceip} DST={destinationip} LEN=60 TOS=0x00 PREC=0x00 TTL=63 ID=20361 DF PROTO=TCP SPT=39950 DPT=37 WINDOW=14600 RES=0x00 SYN URGP=0 On the Internet, I found that DOS attack may cause such type of output, unfortunately, I don't understand what does this log mean. The only thing is clear for me is this log is related to network. The source host is the host where nagios is installed. Does it mean nagios somehow does behave well? And what does it mean at all?

  • git log throws error "ambiguous argument"

    - by LonelyPixel
    This used to work about a year ago. Now it doesn't: git log --abbrev=6 The expected result would be all commit hashes abbreviated to 6 characters. The actual result is now this error message: fatal: ambiguous argument '6': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git [...] -- [...]' I have the impression that Git doesn't even know about that argument and tries to silently ignore its name but not the value. Using Git 1.8.1.msysgit.1 on Windows 7. Addition: Oh and it fails on other parameters, too. The entire command is: git log --abbrev=6 --format=format:"----- Commit %%h on %%ci by %%an -----%%n%%n%%B" If I just leave the abbrev part out, it still returns another error: fatal: Invalid object name 'format'.

  • OpeVPN log connecting client IPs

    - by TossUser
    I looking for the best solution to log all connecting client's ip to either a text file or a database who logs into my VPN server. Under the IP I mean the public WAN IP on the internet where they are connecting from. A hack could definitely be to make the openvpn server log to a separate logfile and run logtail periodically to extract the necessary information. So the database I want to build would look like: Client_Name | Client_IP | Connection_date roadwarr1 | 72.84.99.11 | 03/04/14 - 22:44:00 Sat Please don't recommend me to use the commercial Openvpn Access Server. That's not a real solution here. If the disconnection date could be determined that would be even better so I could see how long a client was connected and from where! Thank you

  • sa2 -A /var/log/sa/sa13: No such file or directory

    - by user53925
    I have systat version 7.0.2 and the /etc/sysconfig/sysstat has the entry HISTORY=27, this is on a redhat enterprise server 5.6, the cron setup for this is # run system activity accounting tool every minute * * * * * root /usr/lib64/sa/sa1 1 1 # generate a daily summary of process accounting at 23:53 53 23 * * * root /usr/lib64/sa/sa2 -A I get the following error from the cron sa2 -A find: /var/log/sa/sa13: No such file or directory, Looking at the directory /var/log/sa the files are created from sa01 through sa10 (sa1 created on sep1, sa2 created on sep2 and so on), then the rest of the files are from sa14 through to sa 31 (created from Aug 14 to Aug 31). I have not made any changes on the server so I am not sure why I am getting these error messages and is there a way to fix this?. Someone suggested creating empty files from sa11 through sa14 to fix this but I am not sure if this might mess up something .

  • Automate Monitor string in different log files

    - by EVIA
    I have few log files in different servers and I want to check output in the end of those log files for e.g . success: 4000 failed: 200 These logs files are getting generated daily and I have to keep track of these numbers. If there is any way I can automate this option instead of going and checking these files and wasting so much of my time. I want to create some kind of script like Go to \serverA\C$\log_07_02_2012.txt and check this line Go to \serverB\C$\log_07_02_2012.txt and check some other line. .... and it should give me output from all of these...

Write Permissions To be able to log in to the blog and writing posts, you need to enable write permissions on the App_Data folder. If you’re blog is hosted at a hosting provider, you can either log into your account’s admin page or call the support. You need write permissions on the App_Data folder because all posts, comments, and blog attachments are saved as XML files and placed in the App_Data folder.  If you wish to use a database to to store your blog data, we still encourage you to enable this write access for an images you may wish to store for your blog posts.  If you are interested in using Microsoft SQL Server, MySQL, SQL CE, or other databases, please see the BlogEngine wiki to get started. Security When you've got write permissions to the App_Data folder, you need to change the username and password. Find the sign-in link located either at the bottom or top of the page depending on your current theme and click it. Now enter "admin" in both the username and password fields and click the button. You will now see an admin menu appear. It has a link to the "Users" admin page. From there you can change the username and password.  Passwords are hashed by default so if you lose your password, please see the BlogEngine wiki for information on recovery. Configuration and Profile Now that you have your blog secured, take a look through the settings and give your new blog a title.  BlogEngine.NET 2.9 is set up to take full advantage of of many semantic formats and technologies such as FOAF, SIOC and APML. It means that the content stored in your BlogEngine.NET installation will be fully portable and auto-discoverable.  Be sure to fill in your author profile to take better advantage of this. Themes, Widgets & Extensions One last thing to consider is customizing the look of your blog.  We have a few themes available right out of the box including two fully setup to use our new widget framework.  The widget framework allows drop and drag placement on your side bar as well as editing and configuration right in the widget while you are logged in.  Extensions allow you to extend and customize the behaivor of your blog.  Be sure to check the BlogEngine.NET Gallery at dnbegallery.org as the go-to location for downloading widgets, themes and extensions.

  • Finally, upgrade from Nokia X3 to Samsung Galaxy S III

    This time, something slightly different but nonetheless not less interesting, hopefully. Living on a remote island like Mauritius, ill-praised 'Cyber Island' in the Indian Ocean, has its advantages in life style and relaxed environment to life in but in terms of technological aspects it can be quite a nightmare. Well, I guess this might be different story to report about... one day. Cyber Island Mauritius Despite it's shiny advertisement as Cyber Island and business in ICT hub to Africa, Mauritius is not on the latest track of available models in computer hardware or, in the context of this article, cellulars or smart-phone, or communication technology in general. Okay, I have to admit that this statement is only partly true. Money can buy, even here in Mauritius. Luckily, there are ways and ways to deal with this outcry of modern, read: technological, civilisation issues. Online shopping you might think? Yes, for sure, until you discover in your checkout procedure that a small island in the Indian Ocean isn't a preferred destination for delivery and the precious time you spent on putting your items into your cart and feeding your personal level of anticipation gets ruined on the last stint. Ordering from abroad saves you money Anyway, I got in touch with my personal courier and luckily there were some extra-kilos left in the luggage. First obstacle sorted, we have a Transporter! Okay, on the next occasion off to Amazon online and using their Prime service for fast delivery. Actually, the order was placed on Saturday evening and everything got delivered on Tuesday morning - nice job in less than 72 hours. Okay, among the items of that shopping rush I ordered a shiny Samsung Galaxy S III 16GB in oceanic blue - did I mention, that you hardly get a blue model in Mauritius? - for my BWE. Interesting side-notes: First, Amazon Germany dropped the prices for roughly 30% on the S3, and we got the 16GB model for less than 500 Euro (or approx. Rs. 19.500,-) compared to the usual Rs. 27.000,- on the local market. It even varies whether the local price is inclusive or exclusive VAT (15%). Second, since a while she was bothering me to get an iPhone and an iPad for her, fair enough I thought, decent hardware, posh design and reliable services. Until we watched the 'magical' introduction of Samsung's new models at the IFA exhibition, she read the bashing comments on Google+ on the iPhone 5 and I gave her a brief summary on the law suit between Apple and Samsung in the USA. So, yes, Samsung USA is right, the next big thing is already here - literally. My BWE loves the look and touch of the Galaxy S3. And for me it was more cost-effective in terms of purchases done at the App Store, ups, Play Store. Transfer of contacts, text messages and media files Okay, now that the hardware is in place, how to transfer all those contacts, text messages, media files, etc. between those two devices? In the past, I used to use the Nokia Communication Suite between various models but now for Android? Well, as usual Google and Bing are reliable friends and among the first hits I came across an article about How to Transfer Contacts from Nokia to Android. Couldn't be easier, right? Well, sort of... my main Windows systems are already running on Windows 8, and this actually caused problems with the mobile/smart-phone device drivers. The article provides the download for an older version 1.10 which upgrades to 2.11 (as time of writing this entry) but both couldn't get the Galaxy S3 and the Nokia connected. Shame on me... the product page clearly doesn't mention Windows 8 (for now) and Windows 8 isn't available for the general audience at all... After I took a spare machine running on Windows Vista everything went smooth. Software installed, upgrade done, device drivers for Android automatically downloaded and installed, and the same painless routine for the Nokia part. I think, I rebooted the system twice during the whole setup procedure but hey, it was more or less a distraction while coding some stuff in ASP.NET MVC and Telerik Kendo UI. The transfer of contacts and text messages was done via Wondershare MobileGo for Android, and all media files by moving the additional microSD card from one device to the other. But even without an external SD card, it would have been very easy to copy the files via Windows Explorer directly. Little catch and excellent service Fine, we are almost done and the only step left is to shift the SIM card... Ouch, gotcha! The X3 uses a standard size SIM card while the S III only accepts microSIM form factor. What an irony, bigger smartphone needs smaller SIM card. Luckily, the next showroom of Emtel is just 5 mins away up the road, and the service staff over there know their job. Finally, after roughly 10 mins of paper work, activation and small chit-chat, the S3 came to life on the mobile network. Owning a smart-phone now and knowing that my BWE would like to interact more on social networks away from home, especially to upload pictures and provide local 'check-ins', I activated a data package for her in advance, too. Even that it is Saturday, everything was already done and ready to be used. Nice bonus: The Emtel clerk directly offered me to set up the configuration for the Emtel data services, yes sure, go ahead, this saves me to search for that in the settings. Okay, spoiler-alert here, setting a static APN to access the Emtel network and the internet wouldn't be a challenge. But hey, she already had the phone in her hands and I could keep my eyes on the children. Well done, Emtel! Resume Thanks to the useful software package by Wondershare is was a hands-free experience to transfer all the data from a Nokia mobile on Symbian S60 to a Samsung Galaxy S III on Android Ice Cream Sandwich (ICS). In the future, this wont be a serious issue at all anymore thanks to synchronisation services and cloud storage. And for now, I'm only waiting for the official upgrades for Jelly Bean.

  • Tracking My Internet Provider Speeds

    - by Scott Weinstein
    Of late, our broadband internet has been feeling sluggish. A call to the company took way more hold-time than I wanted to spend, and it only fixed the problem for a short while. Thus a perfect opportunity to play with some new tech to solve a problem, in this case, documenting a systemic issue from a service provider. The goal – a log a internet speeds, taken say every 15 min. Recording ping time, upload speed, download speed, and local LAN usage.   The solution A WCF service to measure speeds Internet speed was measured via speedtest.net LAN usage was measured by querying my router for packets received and sent A SQL express instance to persist the data A PowerShell script to invoke the WCF service – launched by Windows’ Task Scheduler An OData WCF Data Service to allow me to read the data MS PowerPivot to show a nice viz (scratch that, the beta expired) LinqPad to get the data, export it to excel Tableau Public to show the viz     Powered by Tableau

  • MSR Issue on 12.1 Enterprise Controllers

    - by Owen Allen
    We've noticed a problem with MSR initialization and synchronization on Enterprise Controllers that are using Java 7u45. If you're running into the issue, these jobs fail with Java errors. Java 7u45 is bundled with Oracle Solaris 11.1 SRU 12, so if you're using that version or if you plan to use it, you should be aware of this issue. There's a simple fix. You can do the fix before upgrading to SRU 12, but you can't do it before you install the Enterprise Controller. First, log on to the Enterprise Controller system and stop the EC using the ecadm command. This command is in the /opt/SUNWxvmoc/bin directory on Oracle Solaris systems and in the /opt/sun/xvmoc/bin directory on Linux systems: ecadm stop -w Then run this command to fix the issue: cacaoadm set-param java-flags=`cacaoadm get-param -v java-flags -i oem-ec | sed 's/Xss256k/Xss384k/'` -i oem-ec And then restart the EC: ecadm start -w Once you apply this fix, you should be set.

  • can rsyslog transfer files present in a directory

  • A proper file monitoring tool for Windows with notifications

    - by nevvermind
    Developing in PHP, I'm usually confronted with various log files: apache, web apps, error logs etc. I'm currently using Notepad++ with the option to notify me when a file has changed. But when I need to monitor many files, I end up with too many tabs opened. I've used some of these, but they were lacking some basic stuff (like double clicking on the file to open it; oh, c'mon). What do you guys use for monitoring file changes? I needn't be "modern" or fancy. Just a simple "Hey, this file was changed. Here, click on it to open". (Maybe I'll end up making one myself, but I need to learn some more Java).

  • .NET Reference "Copy Local" True / Fasle Being Set Based on Contents of General Assembly

    - by D-Sect
    Hello All. First question for me here. We had a very interesting problem with a Win Forms project. It's been resolved. We know what happened, but we want to understand why it happened. This may help other people out in the future who have a similar problem. The WinForms project failed on 2 of our client's PCs. The error was an obscure kernel.dll error. The project ran fine on 3 other PCs. We found that a .DLL (log4net.dll - a very popular open-source logging library) was missing from our release folder. It was previously in our release folder. Why was it missing in this latest release? It was missing because I must have installed a program on my Dev box that used log4net.dll and it was added to the general assembly. When I checked the SLN's references for log4net.dll, they were changed to "copy local=FALSE". They must have changed automagicially because log4net.dll was present in my GAC. Here's where my question starts: Why did my reference for log4net.dll get changed from COPY LOCAL = TRUE to COPY LOCAL = FALSE? I suspect it's because it was added to my GAC by another program. How can we prevent this from happening again? As it stands now, if I install a piece of software that uses a common library and it adds it to my GAC, then my SLNs that REF that DLL will change from Copy Local TRUE to FALSE. Thank you so much. I hope this helps people out who have a piece of software that runs in some places, but not in others, when it used to run fine in ALL places.

  • Architecting iPhone Views - seeking help on a specific issue + general advice

    - by Ev
    Hi there, I am a web developer (rails, python) that is new to iPhone development. I've done some desktop development in the past within the MS environment (C#). I'm trying to build a really simple iPhone application and I am confused by the way that views work in general. If someone can provide advice for my particular problem, along with some resources where I can learn how to architect iPhone views in the future, that would be awesome. I feel like a lot of the Apple documentation that I've come across is too specific - I am lacking a fundamental understanding of how views work on the iPhone. My particular problem looks like this: I need one view that displays some downloaded text content. This is the view that shows when the app loads, and it is pretty straightforward. Then I need a settings area (I've already decided I don't want to use the iPhone settings area). The settings area main page will have some text fields on it. It will also have a 2-row grouped table. Each cell in that table will take you to another view which also has a grouped table used for multi-select. I suspect that I can reuse the same view for these two final "detailed setting" views. In summary: home page settings main page detailed setting 1 detailed setting 2 Any help and advice appreciated.

  • Deployments and TFS, general questions

    - by Velika
    SOX requires that we have a separate group deploy our ASP.NET web to production. Currently, that group has access to our current code repository in VSS and uses VSS to deploy code that has been checked into VSS. How are deployments typically done for web applications? As a developer, I have used the Deploy function in Visual Studio to deploy code to a network share which corresponds to a IS virtual folder, but I don't think we can expect that the deployment group will be purchasing a copy of Visual Studio just to do deployments. We could check the code into TFS, but what is the minimum software that that group would need to perform the deployment? Would a Team Explorer Client Access suffice? I am aware that Team System has functionality to automate the building of an application. Do people typically deploy to Production by copying aspx and dlls files from the QA environment to production or do you normally deploy from TFS or even VS directly? It seems to me that the preferred approach would be to deploy from the QA environment, since that is the environment that must have been approved for release or that those files should be checked into TFS and the deployed from TFS, assuming you can deploy from TFS. What confuses me is whether bin (binary) files that are local to the project-do they go into TFS? Is so, doesn't this create problems for other developers in that only 1 developers-the one with the binary checked - can actually debug because debugging requires write access to the binaries? Does this mean that the binaries shouldn't be checked into TFS? But eventually, if you deploy from TFS, the binaries HAVE to be added to TFS. Are they added as a separate (compiled) application node? If so,m this sounds real ugly. I would assume not. How does one ensure that the binaries match the source code that we mark with a particular version number? Obviously, I'm clueless. Can someone give me a general idea of how you handle version control and deployments in particular using TFS?

  • is there an equivalent of a trigger for general stored procedure execution on sql server

    - by Arj
    Hi All, Hope you can help. Is there a way to detect when a stored proc is being run on SQL Server without altering the SP itself? Here's the requirement. We need to track users running reports from our enterprise data warehouse as the core product we use doesn't allow for this. Both core product reports and a slew of in-house ones we've added all return their data from individual stored procs. We don't have a practical way of altering the parts of the product webpages where reports are called from. We also can't change the stored procs for the core product reports. (It would be trivial to add a logging line to the start/end of each of our inhouse ones). What I'm trying to find therefore, is whether there's a way in SQL Server (2005 / 2008) to execute a logging stored proc whenever any other stored procedure runs, without altering those stored procedures themselves. We have general control over the SQL Server instance itself as it's local, we just don't want to change the product stored procs themselves. Any one have any ideas? Is there a kind of "stored proc executing trigger"? Is there an event model for SQL Server that we can hook custom .Net code into? (Just to discount it from the start, we want to try and make a change to SQL Server rather than get into capturing the report being run from the products webpages etc) Thoughts appreciated Thanks

  • Handling data update/freshness issue in web-app in general (or GWT specifically)

    - by edwin.nathaniel
    In general, how do you guys handle user update/data freshness interaction with the user (UI issue) in web-apps? For example: Multi-users web-app (like project management) Login to a "virtual" space People can update project names, etc How to handle a situation such that: user-A and user-B load a project with title "Project StackOverflow" user-B updates the title to "Project StackExchange" user-A updates the title after user-B update operation to "Project Basecamp" The question I'm asking is from the user perspective (UI) and not about transactional operation. What do most people do in this situation? What would you do after user-B updates the title in user-A screen/view? What happened when user-A tries to update the title after user-B finished his/her update operation? do you inform user-A that the title has changed and he/she has to reload the page? do you go ahead and change the title and let user-B has old data? Do you do some sort of application-level "locking" mechanism? (if someone is updating, nobody else can?) Or fix the application workflow? (who has the access to be able to change things, etc). What would be the simplest solution, but at the same time not annoy the user with more dialog/warning messages. I've encountered this particular problem frequently in a GWT app specifically where domain models are being passed around and refreshing the whole app/client-side isn't the optimal solution in my mind (since it means the whole "loading"/initialization phase must be executed again in this specific environment). Maybe the answer is to stay away from GWT? :) Love to hear options, solutions, and advises from you guys. Thanks

  • Designing a general database interface in PHP

    - by lamas
    I'm creating a small framework for my web projects in PHP so I don't have to do the basic work over and over again for every new website. It is not my goal to create a second CakePHP or Codeigniter and I'm also not planning to build my websites with any of the available frameworks as I prefer to use things I've created myself in general. I have no problems in designing that framework when it comes to parts like the core structure, request handling, and so on but I'm getting stuck with designing the database interface for my modules. I've already thought about using the MVC pattern but thought that it would be a bit of a overkill. So the exact problem I'm facing is how my frameworks modules (viewCustomers could be a module, for example) should interact with the database. Is it a good idea to write SQL directly in PHP (mysql_query( 'SELECT firstname, lastname(.....))? How could I abstract a query like SELECT firstname, lastname FROM customers WHERE id=X Would MySQL helper functions like $this->db->get( array('firstname', 'lastname'), array('id'=>X) ) be a good idea? I suppose not because they actually make everything more complicated by requiring arrays to be created and passed. Is the Model pattern from MVC my only real option?

  • general learning methodology

    - by momo
    just wanted to hear on the different general learning paths people embark on when learning a new language/framework. the one i currently use, which is how i learned bash and am currently learning python, is: instant hacking tutorial (very short tutorial introducing the basic syntax, variable declaration, loops, data types, etc. and how they are generally used) in depth tutorial with good programming style and slightly topic-specific (e.g. Mark Pilgrim's Dive into Python), important topics for me personally are regex methods, file IO, and ways the different data types are utilized best (i wrote a very primitive bayesian spam filter using python's dictionaries to keep track of word occurrences) spaced-repition of syntax or short recipes (i use anki, with questions like 'create dictionary with filename and filesize metadata, human-readable' or simpler ones like 'match 0 - 3 occurences of the letter M in a string', or 'return/create an iterator from two sequences') the use of spaced-repitition has been invaluable, and i credit it with the ease that i can recall/create python algorithms. however, i've recently started looking into django, and i've found that spaced-repitition, at least in my case, doesn't work very well for learning a framework, it works best with short code recipes (either that or i should start looking into more basic django framework tutorials). the problem i'm encountering is that since framework programming is not only algorithms, but actually learning the API, which can be quite complex since you have to learn all the methods, modules, the places where they are stored, and the sequence of which things have to be done. for ex. in django to start a project that deals with polls (from the django tutorial), one has to create the project, edit the settings.py file, create the polls app, edit the models.py file (which requires knowing the classes that are present in the module models), edit the urls.py file, etc. i found that my spaced-repition method didn't work very well for this type of learning, so i wanted to ask you guys what method(s) you use for learning the different frameworks/APIs.
