  • Why does '~$ nc -z T43 1-1024' not produce any output although '~$ ping T43' is successful?

    - by user43816
    Why does '~$ nc -z T43 1-1024' not produce any output although '~$ ping T43' is successful? '~$ nc -z -v T43 1-1024' prints 'Connection to T43 22 port [tcp/ssh] succeeded!' and 'nc: connect to T43 port 1000 (tcp) failed: Connection refused.' 'man nc': "PORT SCANNING: It may be useful to know which ports are open and running services on a target machine. The -z flag can be used to tell nc to report open ports, rather than initiate a connection. For example: '$ nc -z host.example.com 20-30'.

  • Redundancy and Automated failover using Forefront TMG 2010 Standard between Production-DR site ?

    - by Albert Widjaja
    Hi, I'm using MS TMG 2010 Standard as my single firewall to publish my Exchange Server and IIS website to the internet, however it is just one VM in the DMZ network with just one network card (vNIC), what sort of redundancy method that is suitable for making this firewall VM redundant / automatically failover in my DR site ? Because it is very important in the event of disaster recovery all important email through various mobile device will still need to operate and it is impossible if this TMG 2010 VM is offline. is it by using: 1. Multicast NLB 2. Any other clustering 3. VMware HA / FT (one VM in production, the other VM in DR site with different subnet ?) Any suggestion and idea willl be appreciated. Thanks

  • Disable "Windows Firewall with Advanced Security" for all profiles(Domain,Public,Standard) in local GP using script help! Windows 7 Clients

    - by JoBo
    We need Windows7 with windows firewall to be turned off , so the GOLD image has windows firewall turned off for all profiles(Domain,Public,Standard) and Windows Service disabled No the same GOLD image deployed with MDT (Apply local GPO) has enabled Windows Firewall under "Windows Firewall with Advanced Security" as part of task sequence Now we need to remove it. "These machines are now on Domain where in we have no rights/control on the domain level GPO", we have local admi rights on these machines We have a requirement do set the "Windows Firewall with Advanced Security" to "NOT Configured" or "OFF "on these machines In gpedit.msc if we manually go to "Windows Firewall with Advanced Security" after enabling Windows Firewall Services then can Clear the settings Do do the same manually on all machines is extra effort Changing values in registry will get reverted on machine restart as its getting applied from local GPO Also using GPMC can connect to remote computer and can manually or using wfw file we can make it not configured but we are looking for a script or a less effort method to accomplish this Please suggest NB: CIA has already reported similar issue//How do I turn off Windows 7 Firewall via script or through automation?// , but doing netsh advfirewall set allprofiles state off on already deployed machines did not make change (FW service on all machine is disabled in GOLd image)// Thanks and Regards Jose

  • Can I run AD commands from a standard PowerShell script?

    - by Ben
    I am putting together a script to run post-sysprep. It should check if the machine is on the network, and if it is then it should query AD to see if a computer account exists with it's service tag (we're using these as the hostnames of the machines.) If it does exist, it should delete the account and rejoin the machine to the domain. I have got the majority of the script running, but need to run the following: Remove-ADComputer -Identity $distinguishedName How can I run this from the "standard" powershell environment? I don't want to use the AD module. (By the way - I'm on a mixed mode 2000/03 domain as we are in the process of upgrading to 2008) I'm new to PowerShell so be gentle if I'm completely missing the point! Thanks, Ben

  • Re-downloading Microsoft SQL Server 2008 Standard because of license issues?

    - by James Watt
    I have many clients who have purchased Microsoft SQL Server 2008 Standard. Unlike other Microsoft software, there is not a serial number provided for each customer to install the software. Futhermore, Microsoft's TechNet website lists this information about SQL Server instead of providing a key: "This product is pre-pidded." This means that the configuration file for SQL server contains your serial number instead of manually entering it. My question is then: does this serial change for each customer? The reason I ask: I'd rather not download a 3.2GB disc image over and over again for each of my customers individually. But, I don't want to risk using the same image over and over again resulting in Microsoft banning the serial for over use (as opposed to each customer using their copy with THEIR serial number.) Thanks in advance.

  • Bash & 'su' script giving an error "standard in must be a tty".

    - by sHz
    Folks, I'm having an issue with a bash script which runs a particular command as a different user. The background: Running on a Linux box (CentOS), the script is quite simple, its starting the hudson-ci application. declare -r HOME=/home/hudson declare -r RUNAS=hudson declare -r HOME=/home/hudson declare -r LOG=hudson.log declare -r PID=hudson.pid declare -r BINARY=hudson.war su - ${RUNAS} -c "nohup java -jar ${HOME}/${BINARY} >> ${HOME}/${LOG} 2>&1; echo $! > ${HOME}/${PID}" & This is the bridged version of the script, when run, the script exists with "standard in must be a tty". Any ideas on what I could be doing wrong? I've tried Dr Google and all the advise hasn't helped thus far.

  • Install Office software on a standard user account automatically.

    - by Earls
    If I know the Administrator account name and password on a Windows 7 computer, would it be possible to create an Office 2010 install CD that would "silently" install Office 2010 on a standard user account which does not have installation privileges. As in, the group policy "always install with elevated privileges" is in effect for the user. Some way to built the admin account privileges into the office installer? VBS Script? CMD? Understand, the laptops are in the field, the end user doesn't have the admin password and can't have the admin password. Thanks.

  • Is PCI Express x4 faster or slower than a standard PCI slot for graphic cards?

    - by Stephen R
    I am looking at potential motherboards for a computer I want to build and ran into this conundrum. The motherboard has two PCI Express slots that allow for 16 channel cards to fit in them. The catch is only one of them operates at 16 channels, the other operates only 4 channels. My question is, would it be faster to buy a PCI Express graphic card and install it in the 4 channel PCI Express slot? Or would it be better to buy a standard PCI graphic card and install it in one of the available PCI slots?

  • How do I ask screen to behave like a standard bash shell?

    - by thornomad
    Just learned about the screen command on linux - it is genius. I love it. However, the actual terminal/prompt in screen looks and behaves differently than my standard bash prompt. That is, the colors aren't the same, tab completion doesn't seem to work, etc. Is there a way I can tell screen to behave just like a normal (at least, normal as in what I am used to) bash prompt ? Additional Information I am connecting via ssh from a Mac (Terminal) to a headless linux box (Ubuntu). After logging in, I have TERM=xterm-color and when I run screen I have TERM=screen. Am going to try the suggestions below to see if I can change the $TERM value first.

  • What does a modern, standard Microsoft-based technology stack look like?

    - by Sean Owen
    Let's say I asked Microsoft to describe the perfect, modern, Microsoft-based technology stack to power a standard e-commerce web site, which perhaps has a simple 2-tier web/database architecture. What would it be like? Yes, I'm just looking for a list of product / technology names. For example, in the J2EE world, I might describe a stack that includes: J2EE 6 standard JavaServer Faces Glassfish 3 MySQL 5.1.x I'm guessing this stack includes some combination of .NET, SQL Server, ASP.NET, IIS, etc. but I am not familiar with this world. Looking for ideas on the equivalent in Microsoft-land.

  • Erlang: How to view output of io:format/2 calls in processes spawned on remote nodes.

    - by jkndrkn
    Hello, I am working on a decentralized Erlang application. I am currently working on a single PC and creating multiple nodes by initializing erl with the -sname flag. When I spawn a process using spawn/4 on its home node, I can see output generated by calls io:format/2 within that process in its home erl instance. When I spawn a process remotely by using spawn/4 in combination with register_name, output of io:format/2 is sometimes redirected back to the erl instance where the remote spawn/4 call was made, and sometimes remains completely invisible. Similarly, when I use rpc:call/4, output of io:format/2 calls is redirected back to the erl instance where the `rpc:call/4' call is made. How do you get a process to emit debugging output back to its parent erl instance?

  • run windows command from bash with output to standard out?

    - by Wayne
    Folks, I'm using git tools such as git bisect run which need to call a command to build and test my project. My command to do is nant which is a windows program. Or a build.cmd script which calls nant. It's easy to get the bash to call the nant build to run. But the hard part is how to get the standard output written to a file? I even installed the Windows PowerShell to try running a command from bash. Again, it works but the standard output fill says "permission denied" when I try to read it while the build is going on.

  • Visual C# 2010 express... displaying console output??

    - by ClarkeyBoy
    Hi, I am currently creating a customer application for a local company. I have a datagridview linked to the customers table, and I am trying to link it up so that updates, inserts and deletions are handled correctly. I am very new to c# so I am starting with the basics (like about 2 days ago I knew nothing - I know vb.net, Java and several other languages though..). Anywho from what I understand anything output through Debug.WriteLine should only appear when in debug mode (common sense really) but anything output through Concole.WriteLine should appear whether or not in debug mode. However I have checked the immediate and output windows and nothing is being output when in normal mode. Does anyone have any idea why this is?? Thanks in advance, Richard

  • Cannot run Python script on Windows with output redirected??

    - by Wai Yip Tung
    This is running on Windows 7 (64 bit), Python 2.6 with Win32 Extensions for Python. I have a simple script that just print "hello world". I can launch it with python hello.py. In this case I can redirect the output to a file. But if I run it by just typing hello.py on the command line and redirect the output, I get an exception. C:> python hello.py hello world C:> python hello.py >output C:> type output hello world C:> hello.py hello world C:> hello.py >output close failed in file object destructor: Error in sys.excepthook: Original exception was: I think I first get this error after upgrading to Windows 7. I remember it should work in XP. I have seen people talking about this bug python-Bugs-1012692 | Can't pipe input to a python program. But that was long time ago. And it does not mention any solution. Have anyone experienced this? Anyone can help?

  • Is there any kind of standard for 8086 multiprocessing?

    - by Earlz
    Back when I made an 8086 emulator I noticed that there was the LOCK prefix intended for synchonization in a multiprocessor environment. Yet the only multitasking I know of for the x86 arch. involves use of the APIC which didn't come around until either the Pentiums or 486s. Was there any kind of standard for 8086 multitasking or was it done by some manufacturer specific extensions to the instruction set and/or special ports? By standard, I mean things like: How do you separate the 2 processors if they both use the same memory? This is impossible without some kind of way to make each processor execute a different piece of code. (or cause an interrupt on only one processor)

  • Can Ruby access output from shell commands as it appears?

    - by Ciryon
    My Ruby script is running a shell command and parsing the output from it. However, it seems the command is first executed and output saved in an array. I would like to be able to access the output lines in real time just as they are printed. I've played around with threads, but haven't got it to work. Any suggestions?

  • What's the best way to run a process remotely with capturing the output ?

    - by Homam
    Hi all, I have a windows service responsible for running processes on a remote machine with capturing the output, I googled for that and read a lot of articles and threads, I found two ways: 1) using WMI for call the remote process like this example: http://www.codeproject.com/KB/cs/EverythingInWmi02.aspx 2) using the PsExec tool by System.Diagnostic.Process class ever way of these has many problems, the WMI doesn't support returning the output and doesn't support "WaitingToExit" It just call the process and return the PId, and the PsExec couldn't capture the output programmatically by System.Diagnostic.Process in a clear way, I found only workarounds like redirect the output to a file then read the redirected file..etc, I need a real solution please

  • Which templating languages output HTML *as a tree of nodes*?

    - by alamar
    HTML is a tree of nodes, before all. It's not just a text. However, most templating engines handle their input and output as it was just a text; they don't care what happens around their tags, their {$foo}'s and <% bar() %>'s; also they don't care about what are they outputting. Sometimes they happen to produce a correct html, but that's just a coincidence; they didn't aim for that, all they wanted is to replace some funny marks in the text stream with their evaluation. There are a few templating engines which do treat their output as a set of nodes; XSLT and Haml come to mind. For some tasks, this has advantages: for example, you can automatically reformat (like, delete all empty text nodes; auto-indent; word-wrap). The result is guaranteed to be a correct xml/sgml unless you use a strict subset of operations that can break that. Also, such templating engine would automatically quote strings, differently in text nodes and in attributes, because it strictly knows whether you're writing an attribute or a text node. Moreover, it can conditionally remove a node from output because it knows where it does begin and end, which is useful, and do other non-trivial node operations. You might not like XSLT for its verbosiness or functionalness, but it's damn helps that your template is xmllint-able XML, and your output is a good sgml/xml. So the question is: Which template engines do you know that treat their output as a set of correct nodes, not just an unstructured text? I know XSLT, Haml and some obscure python-based one. Moar!

  • Standard term for a thread I/O reorder buffer?

    - by Crashworks
    I have a case where many threads all concurrently generate data that is ultimately written to one long, serial file. I need to somehow serialize these writes so that the file gets written in the right order. ie, I have an input queue of 2048 jobs j0..jn, each of which produces a chunk of data oi. The jobs run in parallel on, say, eight threads, but the output blocks have to appear in the file in the same order as the corresponding input blocks — the output file has to be in the order o0o1o2... The solution to this is pretty self evident: I need some kind of buffer that accumulates and writes the output blocks in the correct order, similar to a CPU reorder buffer in Tomasulo's algorithm, or to the way that TCP reassembles out-of-order packets before passing them to the application layer. Before I go code it, I'd like to do a quick literature search to see if there are any papers that have solved this problem in a particularly clever or efficient way, since I have severe realtime and memory constraints. I can't seem to find any papers describing this though; a Scholar search on every permutation of [threads, concurrent, reorder buffer, reassembly, io, serialize] hasn't yielded anything useful. I feel like I must just not be searching the right terms. Is there a common academic name or keyword for this kind of pattern that I can search on?
