• Home server running 2008 R2 intermittently bringing our internet down by creating a large amount of connections [closed]

  - by Philip Strong

  Possible Duplicate: My server's been hacked EMERGENCY My Server 2008 R2 home server is intermittently (every 30 minutes or so, for about 3-4 minutes) creating a huge amount of connections which reaches the 4096 connection limit, thus effectively DOSing our internet connection. I've run a couple of network traffic monitors, and it appears to be a system process causing the problem. I thought I'd fixed it by reinstalling Comodo Antivirus, but it appears that wasn't the problem. Any thought? Thanks in advance.

  - by groovynoob

  I am getting ready to write lot of small experimental java programs as I am studying for java certification. Since I want to avoid using an IDE I'm giving gvim a try. I have a HelloWorld.java file open. How can I run javac and then java and then be able to see the output all in one window? I do not want to alt tab to a dos prompt window. compile/run the program there and then come back to my editor.

• Command Prompt closes on Windows, using Wamp Server commands

  - by Sid

  Hey guys, I am following the tutorial on PHP with MySQL. In that tutorial ebook, they recommend us to use commands to set password for the MySQL. The command goes something like this, "mysqladmin -u root -p status" Now, I am using Windows XP and whenever I enter the command, the dos screen flashes and terminates. I am unable to note down the results, so the question: is there any way to stop command prompt from terminating on Windows machine? Looking forward to hear from you guys, thank you!

• How do I cut and paste commands from your blog?

  - by Maria Colgan

  At the recent ODTUG  Kscope 12 conference several people told me that they really enjoyed our blog on the Optimizer but were frustrated because they couldn’t cut and paste the commands used in the blog posts straight into their environment. Typically I use screen shots in the blog posts to make the commands clear but it does mean that it is impossible to cut and paste the commands into your environment. In order to get around this I have created a downloadable .sql script for each of our blog posts. You should now see the sentence “You can get a copy of the script I used to generate this post here”, appearing at the bottom of each blog post. Clicking on the link will open the .sql script that contains all of the commands used in the post. You can either save the entire script or just cut and paste the particular command you are interested in! I have added scripts for all of this year’s blog posts and am slowly making my way through our old posts until we have a script for everything we have posted to date. Hopefully this will help! +Maria Colgan

• Void in main and keeping Dos program from dying

  - by TimothyTech

  Alright, so im using bloodshed complier, first thing i should note is im using a 2001 edition C++ for the aboslute beginner, was there any changes to C++ since 2001 that would effect the validity of this book? i ask because i know php has php5 and now php6 but i havent seen any C++3. now for the reason i asked that, in this code it uses, void main (void) why would i want an arguement to be void? what does this do. But when i run the " void main (void) in my compiler it says that main must have a "int" before it. so i cant have "void" main (void); also, once the code runs through, as long as there isnt a "cin" the program closes. is this normal behavior, is there a better way to stop this besides making a cin at the end of my program.

• Unable to link to opengl libraries? DOS / MSVC

  - by Mark

  Is there something wrong with this link.exe command line? OpenGL32.lib and Glu32.lib are found at both of the LIBPATH directories. Is it possible the libraries are somehow incompatible? Is there a way to have the link.exe say that instead of unresolved external symbol? Googling shows that this error usually means the libraries are not found, but they are there.

• What should be owner type of a routed command?

  - by viky

  I am using wpf Custom Commands. While writing a custom Command, you need to define the owner type. Description says that it is the type that is registering the command.

• How should I design my database API commands? [closed]

  - by WebDev

  I am developing a database API for a project, with commands for getting data from the database. For example, I have one gib table, so the command for that is: getgib name alias limit fields If the user pass their name: getgib rahul Then it will return all gib data whose name is like rahul. If an alias is given then it will return all the gib owned by the user whose alias (userid) was given. I want to design the commands: limit: to limit the record in query, fields: extra fields I want to add in the select query. So now the commands are set, but: I want the gibs by the gibid, so how to make this or any suggestion to improve my command is welcome. If the user doesn't want to specify the name, and he wants only the gibs by providing alias, then what separator should I use instead of name?

• processing gamestate with a window of commands across time?

  - by rook2pawn

  I have clients sending client updates at a 100ms intervals. i pool the command inputs and create a client command frame. the commands come into the server in these windows and i tag them across time as they come in. when i do a server tick i intend to process this list of commands i.e. [ {command:'duck',timestamp:350,player:'a'}, {command:'shoot',timestamp:395,player:'b'}, {command:'move', timestamp:410,player:'c'} {command:'cover',timestamp:420,player:'a'} ] how would i efficiently update the gamestate based on this list? the two solutions i see are 1) simulate time via direct equation to figure out how far everyone would move or change as if the real gameupdate was ticking on the worldtick..but then unforseen events that would normally trigger during real update would not get triggered such as powerups or collissions 2) prepare to run the worldupdate multiple times and figure out which commands get sent to which worldupdate. this seems better but a little more costly is there a canonical way to do this?

• Python (pdb) - Queueing up commands to execute

  - by kpatelPro

  I am implementing a "breakpoint" system for use in my Python development that will allow me to call a function that, in essence, calls pdb.set_trace(); Some of the functionality that I would like to implement requires me to control pdb from code while I am within a set_trace context. Example: disableList = [] def breakpoint(name=None): def d(): disableList.append(name) #**** #issue 'run' command to pdb so user #does not have to type 'c' #**** if name in disableList: return print "Use d() to disable breakpoint, 'c' to continue" pdb.set_trace(); In the above example, how do I implement the comments demarked by the #**** ? In other parts of this system, I would like to issue an 'up' command, or two sequential 'up' commands without leaving the pdb session (so the user ends up at a pdb prompt but up two levels on the call stack. Thanks!

• Batch file script to remove special characters from filenames (Windows)

  - by njreed.myopenid.com

  I have a large set of files, some of which contain special characters in the filename (e.g. ä,ö,%, and others). I'd like a script file to iterate over these files and rename them removing the special characters. I don't really mind what it does, but it could replace them with underscores for example e.g. Störung%20.doc would be renamed to St_rung_20.doc In order of preference: A DOS batch file A Windows script file to run with cscript (vbs) A third party piece of software that can be run from the command-line (i.e. no user interaction required) Another language script file, for which I'd have to install an additional script engine Background: I'm trying to encrypt these file with GnuPG on Windows but it doesn't seem to handle special characters in filenames with the --encrypt-files option.

• Batch File input validation - Make sure user entered an integer

  - by B2Ben

  I'm experimenting with a DOS batch file to perform a simple operation which requires the user to enter a non-negative integer. I'm using simple batch-file techniques to get user input: @ECHO OFF SET /P UserInput=Please Enter a Number: The user can enter any text they want here, so I would like to add some routine to make sure what the user entered was a valid number. That is... they entered at least one character, and every character is a number from 0 to 9. I'd like something I can feed the UserInput into. At the end of the routine would be like an if/then that would run different statements based on whether or not it was actually a valid number. I've experimented with loops and substrings and such, but my knowledge and understanding is still slim... so any help would be appreciated. I could build an executable, and I know there are nicer ways to do things than batch files, but at least for this task I'm trying to keep it simple by using a batch file.

• How to execute several batch commands in sequence

  - by ptikobj

  I want to create a Windows XP batch script that sequentially performs something like the following: @echo off :: build everything cd \workspace\project1 mvn clean install cd ..\project2 mvn clean install :: run some java file cd \workspace\project3 java -jar somefile.jar When I create a Batch script like this (following these instructions), I still have the problem that the script stops doing something after the first mvn clean install and then displays the command line. How can i execute all of these commands in sequence in one batch file? I don't want to refer to other files, I want to do it in one file.

• Eclipse RCP: Actions vs Commands - would like an update

  - by nEm

  I know this question has been asked before but it was in 2009 and I haven't found anything more recent either on the web. I was wondering if the answer in that still holds or can it be updated? I am just starting work on an RCP and I haven't been able to decide between actions and commands for my menu items. I will be using a lot of the ones provided by Eclipse such as the Edit, File and some of their sub menu items as well. Since it has been nearly two years for the answer provided in the '09 question, I just wanted to make sure there is nothing else that could sway my decision in either direction or maybe if there have been some new developments that I am not aware of.

• Interacting with system commands using a web dev language

  - by Jamie

  Hi all, First of all, sorry for the vague title. Let me explain. At work we're currently using SunGrid I've been assigned a project to create a web interface wrapper for interacting with the engine. i.e. displaying users jobs, submitting jobs via a nice GUI etc. (most of the sgrid commands output xml which is nice) My question for you chaps is the following: What web dev language would you use to interact with the system? i.e. use the language to do a system call and evaluate the response. I'm not after an argument on which language is best, I just would like to know which language is specifically good for interacting with the system and is also good for web dev.

• Executing multiple commands from a Windows cmd script

  - by Darren Greaves

  I'm trying to write a Windows cmd script to perform several tasks in series. However, it always stops after the first command in the script. The command it stops after is a maven build (not sure if that's relevant). How do I make it carry on and run each task in turn please? Installing any software or configuring the registry etc is completely out of the question - it has to work on a vanilla Windows XP installation I'm afraid. Ideally I'd like the script to abort if any of the commands failed, but that's a "nice to have", not essential. Thanks.

• Only some windows shell commands work via ruby?

  - by Sanarothe

  Hi. I'm trying to use a script to control my power options since XP doesn't give you an intuitive way to change CPU Frequency options. Here's my script so far: meh = `cmd.exe /C POWERCFG.EXE /QUERY Portable/Laptop` puts "" puts meh case input when 1 then system('cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac NONE') when 2 then system('cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac ADAPTIVE') when 3 then `cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac CONSTANT` end The problem is that the changes simply don't take place. If I run the same commands directly into a cmd.exe prompt, they work. It's very strange, but nothing works after the initial powercfg query. I feel like I'm missing something incredibly obvious. How can I get the above script to run correctly?
