  • Does operator new allocate on THREAD heap?

    - by Jonas Byström
    My problem seems to be this: heap data allocated by one thread (that later dies) seems to die as well. As so: Thread X: starts Thread Y: starts Thread X: ptr = new some bytes Thread X: dies Thread Y: tries to use ptr - and crashes! So far, I've only seen this problem on Darwin (Mac OS 10.5 and 10.6), but haven't tried more other platforms than Windows and Linux (Ubuntu) where it works as expected. I've had this problem for some time, so any know-how or more information about this is highly appreciated!

  • Should I upgrade Exchange 2003 or just upgrade the hardware?

    - by JohnyD
    My organization currently has a 4 y/o Exchange 2003 email server (32-bit, Intel Pentium D @ 3GHz, 3GB RAM). It's run very well over the past 4 years but it is time to upgrade its hardware. This server would handle email for approximately 30 clients, a few OWA users with iPhones. My (somewhat ambiguous) question is, when I receive the new hardware should I build out a new Exchange 2003 deployment or should I look at Exchange 2007 / 2010? I've heard that Exchange 2010 requires Sharepoint 2010 (which I am currently not running). Are there benefits that a small-medium sized business can or can't do without? Am I making a horrible mistake staying with antiquated software? Other details: Exchange 2003 (v6.5 + SP2) single front-end server All opinions and thoughts are very much appreciated.

  • how to connect public web server to internal LAN

    - by DefSol
    I have a VPS which is my public web server for all my clients. It's running server 2008 and I would like to have it connect via secure connection to my internal LAN. I would like this to be a route so access is bi-derectional. Have read about Server & Domain isolation, but am concerned this may prevent public views to the webs sites on the server. I currently have a PPTP tunnel, but I'm wanting better security (IPSec or SSL etc) and it's not given my bi derectional access. (In fact my backups aren't copying accross but this could be an acl issue) The goal is to provide easy/automated backups of data & sql db's to my internal LAN, as well as a means to provision new sites & db's from a workflow occuring internally. Internal lan is windows based with ISA 2006 at the perimeter. Thanks

  • Protecting PHP packages on server

    - by Jack
    Hi, I am a php developer and have recently decided to make one of my Magento extensions commercial. I have downloaded and configured MageParts CEM Server and that is all working perfectly in regard to licencing and delivery of module packages. The only issue is that the directory that the packages are stored in could be accessed by anyone. I tried this in a .htaccess file, but now it is not working. <Files services.wsdl> allow from all </Files> deny from all Clients are receiving a 403 Forbidden response. Have I done something wrong in the .htaccess file or would there be a better way to secure the directory? Any help would be greatly appreciated.

  • graph performance monitor windows and linux

    - by Patrik
    We are using Munin to get graphs of our servers. (such as CPU load, I/O, available disk space, etc. ) Munin gives us last 24h, last 7 days, last month and last year. The good thing with Munin is that it supports all kinds of clients, such as Windows, Linux and switches because it can monitor over SNMP. However, we have a problem with the Munin client for Windows. Since we upgraded to Windows Server 2008 R2 it won't show graphs for some performance counters. What options are there out there? Both free and commercial.

  • UDP Reverse Proxy

    - by user180195
    I have found a way to make reverse-proxy to an external IP. Here is how someone making a request will see it's request being passed: Clients sends request Request reaches the Datacenter one in some place That datacenter, acting as a reverse proxy will redirect the same exact request to another datacenter. The datacenter will then process the request Although, this only works with TCP/HTTP (Looking currently at HaProxy). I am hosting game servers at the other datacenter (where the proxy is not) that are using UDP protocol. Do you know how can I setup a reverse proxy using the UDP protocol.

  • How do I configure pfsense as an outbound VPN client?

    - by Avery Chan
    We use pfsense as a router/firewall. Because we're based in China, it is useful for us to have VPN access for all our internal clients. Instead of each individual client connecting to a VPN server stateside, I'd like to configure pfsense as a VPN client and have all the network traffic be routed through it. Most of the posts I've seen regarding pfsense and VPN are concerning connecting to the LAN from outside; this is not what I want to do. Another option would be for an SSH tunnel to be initiated on the pfsense box with the LAN traffic routed through it. How do I configure pfsense to be able to do either of these? One huge caveat is that OpenVPN cannot be used. The solution I am looking for needs to use one of the other VPN protocols.

  • Windows 8 cannot connect remotely to Windows Server 2012

    - by raza naqvi
    I have installed Windows Server 2012 and then configured remote applications. At first it was working fine and I could be able to connect remotely and run remote applications from Windows 8 clients. But after few days the following error occurred: Remote Desktop Connection This computer can't connect to the remote computer. Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator. However I still can connect from Windows 7 without any problem. Only Windows 8 has a problem and cannot connect remotely. Neither remote apps nor RDP is working.

  • Solaris TCP/IP performance tuning

    - by Andy Faibishenko
    I am trying to tune a high message traffic system running on Solaris. The architecture is a large number (600) of clients which connect via TCP to a big Solaris server and then send/receive relatively small messages (.5 to 1K payload) at high rates. The goal is to minimize the latency of each message processed. I suspect that the TCP stack of the server is getting overwhelmed by all the traffic. What are some commands/metrics that I can use to confirm this, and in case this is true, what is the best way to alleviate this bottleneck? PS I posted this on StackOverflow originally. One person suggested snoop and dtrace. dtrace seems pretty general - are there any additional pointers on how to use it to diagnose TCP issues?

  • enable offline files for all users home drives via Group policy or other

    - by JohnyV
    I am trying to get all users of particular notebooks to make the users h drive offline. i know you can do it manually but is there a way to set this value somewhere so that users dont have to do it themselves? I am running 2008r2 domain controllers and windows 7 clients. I have folder redirection enabled but i want to make the users h: available to them when they are offline. I know the group policies are located in the computer configurationPoliciesadministrative templatesNetwork but there doesnt seem to be any place to select which folders/drives will be offline files without a users input. Even if there is another method not through GP. Thanks

  • Forward emails from specific domain in Exchange

    - by neildeadman
    Our Exchange server handles emails for @ourdomain.com (for example). We have multiple clients that will send emails to our [email protected] email address and we want to configure server-side rules that will forward emails from each client's domain to a different email address within our exchange server. For example: [email protected] sends an email to [email protected] and we forward it to [email protected] [email protected] sends an email to [email protected] and we forward it to [email protected] ...and so on. It would be nice if we can additionally stop the email arriving in the [email protected] mailbox, but that is not a specific requirement. We have a rule setup in Outlook that sort of works, but it doesn't do all from a domain only specific email addresses. It does work when Outlook is not running which is a start. I realise it would be easier to give each client a partiuclar email address and have them email straight to that rather than all use the same, but this is what I have been asked to setup.... :S

  • How do I get through proxy server environments for non-standard services?

    - by Ripred
    I'm not real hip on exactly what role(s) today's proxy servers can play and I'm learning so go easy on me :-) I have a client/server system I have written using a homegrown protocol and need to enhance the client side to negotiate its way out of a proxy environment. I have an existing client and server system written in C and C++ for the speed and a small amount of MFC in the client to handle the user interface. I have written both the server and client side of the system on Windows (the people I work for are mainly web developers using Windows everything - not a choice) sticking to Berkeley Sockets as it were via wsock32 for efficiency. The clients connect to the server through a nonstandard port (even though using port 80 is an option to get out of some environments but the protocol that goes over it isn't HTTP). The TCP connection(s) stay open for the duration of the clients participation in real time conferences. Our customer base is expanding to all kinds of networked environments. I have been able to solve a lot of problems by adding the ability to connect securely over port 443 and using secure sockets which allows the protocol to pass through a lot environments since the internal packets can't be sniffed. But more and more of our customers are behind a proxy server environment and my direct connections don't make it through. My old school understanding of proxy servers is that they act as a proxy for external HTML content over HTTP, possibly locally caching popular material for faster local access, and also allowing their IT staff to blacklist certain destination sites. Customer are complaining that my software doesn't recognize and easily navigate its way through their proxy environments but I'm finding it difficult to decide what my "best fit" solution should be. My software doesn't tear down the connection after each client request, and on top of that packets can come from either side at any time, basically your typical custom client/server system for a specific niche. My first reaction is "why can't they just add my servers addresses to their white list" but if there is a programmatic way I can get through without requiring their IT staff to help it is politically better and arguably a better solution anyway. Plus maybe I'm still not understanding the role and purpose of what proxy servers and environments have grown to be these days. My first attempt at a solution was to use WinInet with its various proxy capabilities to establish a connection over port 80 to my non-standard protocol server (which knows enough to recognize and answer a simple HTTP-looking GET request and answer it with a simple HTTP response page to get around some environments that employ initial packet sniffing (DPI)). I retrieved the actual SOCKET handle behind WinInet's HINTERNET request object and had hoped to use that in place of my software's existing SOCKET connection and hopefully not need to change much more on the client side. It initially seemed to be my solution but on further inspection it seems that the OS gets first-chance at the received data on this socket since when I get notified of events via the standard select(...) statement on the socket and query the size of the data available via ioctlsocket the call succeeds but returns 0 bytes available, the reads don't work and it goes downhill from there. Can someone tell me of a client-side library (commercial is fine) will let me get past these proxy server environments with as little user and IT staff help as possible? From what I read it has grown past SOCKS and I figure someone has to have solved this problem before me. Thanks for reading my long-winded question, Ripred

  • What is the best way to create RAID 1?

    - by user3125731
    I'm looking for a way to create the RAID 1 array without losing my data on CentOS. Here's my situation: I've got a web server running on CentOS. There is one VG partition with few LV volumes. I bought a second HDD (the same model and size as the first one) and I want to create the RAID 1 configuration. I can't just shut down this server for more than an hour because my clients will be disappointed. I need to do this as quickly as possible with minimal risk of data loss.

  • How to know when a user has really released a key in Java?

    - by Luis Soeiro
    (Edited for clarity) I want to detect when a user presses and releases a key in Java Swing, ignoring the keyboard auto repeat feature. I also would like a pure Java approach the works on Linux, Mac OS and Windows. Requirements: When the user presses some key I want to know what key is that; When the user releases some key, I want to know what key is that; I want to ignore the system auto repeat options: I want to receive just one keypress event for each key press and just one key release event for each key release; If possible, I would use items 1 to 3 to know if the user is holding more than one key at a time (i.e, she hits 'a' and without releasing it, she hits "Enter"). The problem I'm facing in Java is that under Linux, when the user holds some key, there are many keyPress and keyRelease events being fired (because of the keyboard repeat feature). I've tried some approaches with no success: Get the last time a key event occurred - in Linux, they seem to be zero for key repeat, however, in Mac OS they are not; Consider an event only if the current keyCode is different from the last one - this way the user can't hit twice the same key in a row; Here is the basic (non working) part of code: import java.awt.event.KeyListener; public class Example implements KeyListener { public void keyTyped(KeyEvent e) { } public void keyPressed(KeyEvent e) { System.out.println("KeyPressed: "+e.getKeyCode()+", ts="+e.getWhen()); } public void keyReleased(KeyEvent e) { System.out.println("KeyReleased: "+e.getKeyCode()+", ts="+e.getWhen()); } } When a user holds a key (i.e, 'p') the system shows: KeyPressed: 80, ts=1253637271673 KeyReleased: 80, ts=1253637271923 KeyPressed: 80, ts=1253637271923 KeyReleased: 80, ts=1253637271956 KeyPressed: 80, ts=1253637271956 KeyReleased: 80, ts=1253637271990 KeyPressed: 80, ts=1253637271990 KeyReleased: 80, ts=1253637272023 KeyPressed: 80, ts=1253637272023 ... At least under Linux, the JVM keeps resending all the key events when a key is being hold. To make things more difficult, on my system (Kubuntu 9.04 Core 2 Duo) the timestamps keep changing. The JVM sends a key new release and new key press with the same timestamp. This makes it hard to know when a key is really released. Any ideas? Thanks

  • Problem compiling c++ in CodeGear

    I have written a C++ program for a University assignment. I used Netbeans 6.8 running on my Mac and the code runs smoothly, no warnings, errors or problems/bugs.

  • Vista laptop won't connect to airport extreme

    - by Hutch
    Our previous router died, and to replace it I procured an apple airport extreme. My mac, my wrt54gs (with ddwrt acting as a bridge) and a linux machine have had no problem connecting to the wireless. None of the wired clients are having a problem obviously. The problem is one of my roommates can not connect. That's not strictly true. He can connect to the network, and will, infact, get a dhcp lease. However he cannot get any packets out. Can't ping the router, can't access any web sites, nothing. However he's fine if we switch to an unsecured network. Which is obviously not acceptable. The airport only allows for 'wpa/wpa2 personal' and 'wpa2 personal' (and of course the enterprise versions there of) I keep reading about this problem in multiple spots on the web, but never see any actual answers... Anyway the laptop: hp/compaq cq50-215nr vista home premium wireess card: atheros 5007 airport is simultaneos dualband II
