• Make ZoneAlarm stop pausing my C programs when I run them

  - by rMaero

  I'm using Dev-C++ to develop some console apps to study. When my program tries to run system("PAUSE"); ZA stops it and asks me to allow or deny it. I check the "always" box but it seems that every time I compile it, it generates a new exe file so every time I run it ZA pops up. Of course the simplest solution is to disable it or deal with it :-P but I'm not eager for any of both. Any suggestions? thanks in advance!

• Need to get a file written to a floppy.

  - by dboarman-FissureStudios

  I asked this question over on SO. I have tried dd if=kernel.sys of=/dev/fd0 bs=512 seek=1 to get this file to write to the floppy. It is a kernel shell that must be written to the sector immediately following the bootsector of a disk to boot the PC. No matter what I've tried, for some reason, kernel.sys is not writing to the floppy. I know the bootstrap loader is being written and executed. However, it cannot find the kernel to load the shell. Any ideas on what I am doing wrong? I mean, really, how is it so difficult to get this file written to a floppy? OpenSUSE 11.2

• Procmail Mailing List (With Access Control)

  - by bradlis7

  This seems like it should be fairly easy to do, but I've run into a few problems. I've added a cron job to parse all users whose UID is greater than 5000: * * * * * root /usr/bin/test /etc/passwd -nt ~allusers/.forward \ && /bin/egrep '([5-9]|[0-9]{2})[0-9]{3}' /etc/passwd | /bin/grep -v 65534 \ | /bin/cut -d ':' -f 1 > ~allusers/.forward Then I created a .procmailrc file: VERBOSE=yes LOGFILE=/var/log/procmailrc #Allow only certain users to send :0 * ^From.*[email protected].* {} :0E /dev/null But, the .forward file is processed before it even gets to procmail, evidently. If I moved the .forward file to another filename, can I use it in procmail to send an email to the users in this file?

• Why does Google Reader use up so much memory?

  - by Ivo

  I'm running the dev version of Chrome and just found out I could see the memory usage of every tab (press shift + ESC to find out yourself). Turns out the Shockwave Flash plugin uses 240 MB of memory and 27% of CPU while having open Google Reader. Killing this page brings it down to 50 MB. I reckon it builts up after reading through about 100 feeds. So my question is: why does it take up so much memory and what should I do to diminish it? Why I care? I often don't restart my browser (or laptop for that matter) and keep the Google Reader tab open for long periods of time. The memory does start to add up that way. Plus I have the feeling, perhaps incorrect, that it slows things down as well looking at the CPU usage. Side note: using Chrome 4 on Windows 7 (32 bit)

• Unable to use NTFS partition for Dropbox in Linux

  - by Cristian

  Dropbox won't let me choose the sync folder inside a NTFS partition. First thought I had was mounting and its permissions (the Dropbox installer does let me choose my linux home as the Dropbox home). After searching and trying several other lines, the partition is mounted via fstab with these settings: /dev/sda5 /mnt/documents ntfs-3g uid=1000,gid=100,dmask=027,fmask=137 0 0 I can read and write in the partition, here is a ls output: 24 drwxr-x--- 1 tuxcayc users 24576 Sep 2 06:42 documents I'm using an Arch-based distro (Manjaro) and Dropbox installed via yaourt. I guess it's still some issue with mounting permissions. Any help is appreciated, Thanks.

• How Do I make an Acer T230H Touchcreen work on Ubuntu 9.10?

  - by N Rahl

  I've done this so far: sudo nano /etc/udev/rules.d/99-touchscreen.rules And added: SUBSYSTEM=="usb", ATTRS{idVendor}=="0408", ATTRS{idProduct}=="3000", SYMLINK+="usb/quanta_touch" SUBSYSTEM=="input", KERNEL=="event*", ATTRS{idVendor}=="0408", ATTRS{idProduct}=="3000", SYMLINK+="input/quanta_touch" sudo service udev restart then the instructions here: http://ubuntuforums.org/showpost.php?p=8932808&postcount=36 And then added to my xorg conf: Section "InputDevice" Identifier "Acer T230H" Driver "hidtouch" Option "SendCoreEvents" "true" Option "ReportingMode" "Raw" Option "Device" "/dev/usb/quanta_touch" Option "PacketCount" "13" Option "OpcodePressure" "852034" Option "OpcodeX" "65584" Option "OpcodeY" "65585" Option "CalibrationModel" "1" Option "CornerTopLeftX" "0" Option "CornerTopLeftY" "0" Option "CornerTopRightX" "1920" # 1920 for 23" Option "CornerTopRightY" "0" Option "CornerBottomLeftX" "0" Option "CornerBottomLeftY" "1080" # 1080 for 23" Option "CornerBottomRightX" "1920" # 1920 for 23" Option "CornerBottomRightY" "1080" # 1080 for 23" Option "CornerScreenWidth" "1920" # 1920 for 23" Option "CornerScreenHeight" "1080" # 1080 for 23" EndSection Section "ServerLayout" Identifier "Touchscreen" InputDevice "Acer T230H" "SendCoreEvents" EndSection And restarted. And the touchscreen does nothing. Any ideas?

• Which app has a notification sound with 3 descending notes?

  - by Eric

  Brand new Windows 7 box loaded with the usual dev tools -- VS2008, Firefox, Chatzilla, Thunderbird, emacs, Pidgin, Putty, iTunes, SharpReader. Every couple of minutes, I get an audio notification consisting of three rising notes, maybe a middle-C-G-F on a piano (I don't have a piano handy, and don't have time to use GarageBand to try to figure it out). Nothing in the notification bar is flashing when this happens. The sound isn't in any of the Windows Sound control panel applets. And it's not in C:\Windows\Media, so it's most likely coming from a non-Microsoft app. Any chance it's Pidgin when the status one of my contact's changes (which happens plenty frequently)? Oh, look at this --- Tools/Mute Sounds. Let's try that and see what happens... Is this familiar to anyone?

• Is there a simple Load Balancer app for development environment on Windows?

  - by djangofan

  Does there exist a simple Load Balancer app for development on Windows? I am running a pair of JBoss 5.x instances in a cluster on a single machine. Normally , this configuration is load balanced by a nice hardware load balancer but I am wondering if there is a simple piece of software to enable load balancing in my Eclipse dev environment. Basically, for example, I want a load balancer running on port 11111 that round-robins between the 2 clustered JBoss instances on ssl ports 8443 and 8543 . (or http port if thats not possible) I know that Glassfish has a built-in load balancer but I can't use Glassfish. One idea I have is to try to setup a separate instance of Tomcat with the "balancer" web app. Im trying that now... not sure if it will work... and its a complicated setup and I wish there was something really easy.

• Trouble editing ~/.bash_profile: -bash: $'\r': command not found

  - by Dave

  I installed CygWin on Windows 7. Using Notepad, I edited my ~/.bash_profile file to add on to the PATH variable … PATH="${PATH}:/cygdrive/c/apache-ant-1.8.2/bin" Now, when I SSH in to my Windows machine, I get this error … -bash: $'\r': command not found -bash: $'\r': command not found -bash: $'\r': command not found -bash: $'\r': command not found -bash: $'\r': command not found -bash: /home/dev/.bash_profile: line 39: syntax error: unexpected end of file and my PATH is not set. Anyone know how I can correct this?

• Force local IP traffic to an external interface

  - by calandoa

  I have a machine with several interfaces that I can configure as I want, for instance: eth1: 192.168.1.1 eth2: 192.168.2.2 I would like to be able to forward all the traffic to one of these local address trhough the other interface. For instance, all requests to an iperf, ftp, http server at 192.168.1.1 are not just routed internally, but forwarded through eth2 (and the external network will take care of re-routing the packet to eth1). I tried and looked at several commands, like iptables, ip route, etc... but nothing worked. The closest behavior I could get was done with: ip route change to 192.168.1.1/24 dev eth2 which send all 192.168.1.x on eth2, except for 192.168.1.1 which is still routed internally. The goal of this setup is to do interface driver testing without using two PCs. I am using Linux, but if you know how to do that with Windows, I'll buy it!

• Mantaining Wordpress website with subversion

  - by Geries

  I want to setup a website using wordpress, which we can modified locally and then via subversion commit the site and make it public. This means to installing new plugins, changing the content, testing updates of wordpress to see if they work with the theme, etc. The idea is to control the development on the site, in case we need to keep track of the dev or roll back, because of unexpected bugs in a the plugins, theme, etc. I've read this article in codex, however I'm not sure how this is done when, we want to include the content and changes on the options of worpdress and plugins (which is in the mysql). Thanks

• Netinstalling CentOS if the gateway is in a different subnet

  - by James Lawrie

  I have a KVM host (A) running a virtual machine (B). They each have their own external IP address and the networking is setup using bridging between eth0 and br0 on A. B uses eth0, with A being the gateway. The problem is that the two external IP addresses are on different subnets (different /8s in fact) so by default, B claims it cannot reach A (Network Unreachable). I can resolve this by adding a static route on B: echo "any host gateway_ip dev eth0" > /etc/sysconfig/static-routes Modifying /etc/init.d/networking to reload the gateway after applying static routes (I only added the final line before fi): if [ -f /etc/sysconfig/static-routes ]; then grep "^any" /etc/sysconfig/static-routes | while read ignore args ; do /sbin/route add -$args done route add default gw "${GATEWAY}" fi If I then restart networking, it comes online. How can I do this (or work around it some other way) prior to the system being installed, ideally inside an Anaconda kickstart file?

• Flash not Working in Google Chrome for Mac

  - by Blakeasd

  Flash has randomly stopped working in Google Chrome for Mac. All that appears is a white flash then nothing. I can hear sound, and when I right click on where Flash is supposed to be I see the Flash Player options. I have completely reinstalled Chrome, including deleting all of its support files. I reinstalled my system flash and tried making Chrome use my system flash, but nothing works. Flash is fine in Safari, but not in Chrome. How do I fix this? I am running the latest Google Chrome Dev build (21.0.1171.0) and Mac OS X 10.7.4 . Thanks!

• Netboot Debian (wheezy) from NFS v4

  Is it possible to boot Debian Wheezy from NFS v4? Bootwing with NFS v3 works just fine. NFS v4 not. This is in my /etc/exports: /nfs 192.168.100.0/24(ro,sync,insecure,no_root_squash,no_subtree_check,fsid=0) /nfs/root 192.168.100.0/24(ro,nohide,sync,insecure,no_root_squash,no_subtree_check) /nfs/root/www contains the root of the webserver.

• Exim queue in WHM

  - by Xobb

  Hi fellas, I've got the centos server with WHM. The mail server is exim. I need exim put all messages in queue and not sending directly.Though I've added the queue_only option to exim configuration and the messages are collected in the queue now. Afterwards I've found out that someone is calling exim -q to process the queue every once in a while. I've found the following cron job: 0 6 * * * /scripts/exim_tidydb > /dev/null 2>&1 which I beleive has been used to process the exim queue. Also I suspect that script was installed alongside with WHM. Surely I've commented it out and was expecting everything to work just fine. But that didn't happen. I still get the exim queue processed once in a while. Am I missing anything? What may cause my exim queue to process? Here is cat /etc/exim.conf | grep queue queue_only deliver_queue_load_max = 3 Thanks

• How to determine the used size of device associated's buffer

  - by dubbaluga

  Hi, when mounting a device without the "sync" option, e. g. by invoking the following: mount -o async /dev/sdc1 /mnt a buffer is associated with a device to optimize (speed) read/write operations. Is there a way to determine the size of this buffer? Another question that comes into my mind is, if it's possible to find out how much of it is used currently. This can be interesting to determine the time it would take to "sync" or "umount" slow devices, such as flash-based media. Thanks in advance for your answers, Rainer

• Outputting SVN hook messages

  - by Luke Segars

  Hi all, I have a subversion repository on my Linux machine that is set up to export a new build of a project every time a new commit occurs using a post-commit hook. I would really like to be able to provide an output message to the committer containing some status information once the hook completes. Is it possible to redirect the output of the hook to come after the standard commit messages? For example: owner@dev-machine:/working/dir$ svn commit Sending FILE1 Sending FILE2 Transmissing file data ... Committed revision 13. Exporting project... Successfully exported to mysite.com The addition of the last two lines is the functionality I'm looking for.

• Proxmox 31 + KVM routing + IP subnet + csf

  - by KeyJey

  We have proxmox 3.1 server in netzner with routuing network and IP subnet block. We want to implement csf firewall without interfering the traffic of the KVM VMs, what would be the easiest way? We readed that we should add this lines to /etc/csf/csfpost.sh: iptables -A FORWARD -d 144.76.223.155 -j ACCEPT iptables -A FORWARD -d 144.76.223.156 -j ACCEPT iptables -A FORWARD -d 144.76.223.157 -j ACCEPT iptables -A FORWARD -d 144.76.223.158 -j ACCEPT iptables -A FORWARD -d 144.76.223.159 -j ACCEPT iptables -A FORWARD -d 144.99.183.323 -j ACCEPT But when we enable csf the ping breaks, this is the network config (IPs are modified): auto lo iface lo inet loopback # device: eth0 auto eth0 iface eth0 inet static address 144.76.166.100 netmask 255.255.255.255 pointopoint 144.76.183.97 gateway 144.76.183.97 # for single IPs auto vmbr0 iface vmbr0 inet static address 144.76.166.100 netmask 255.255.255.255 bridge_ports none bridge_stp off bridge_fd 0 up ip route add 144.99.183.323/32 dev vmbr0 # for a subnet auto vmbr1 iface vmbr1 inet static address 144.76.166.100 netmask 255.255.255.248 bridge_ports none bridge_stp off bridge_fd 0 Thanks in advanced ! :)

• What is the harm in giving developers read access to application server application event logs?

  - by Jim Anderson

  I am a developer working on an ASP.NET application. The application writes logging messages to the Windows event log - a custom application log just for this application. However, I do not have any access to testing or staging web/application servers. I thought an admin could just give me read access to this event log to help in debugging problems (currently a service that is working in dev is not working in test environment and I have no idea why) but that is against my client's (I'm a consultant) policy. I feel silly to keep asking an admin to look at the event log for me. What is the harm in giving developers read access to application server application event logs? Is there a different method of application logging that sysadmins prefer programmers use? Surely, admins don't want to be fetching logging messages for developers all the time.

• Very slow disk performance on Dell PowerEdge 2950 w/ PERC 6/i running RAID 10

  - by vocoder

  I recently set up a server running Ubuntu 10.04 LTS on a Dell PowerEdge 2950 server - it has 6 500 gb 7200RPM SATA drives setup in a RAID 10 config. I am seeing extremely poor disk performance - the RAID array reports all disks are normal and using MegaCLI, it looks like the BBU is fine. hdparm -tT /dev/sda reports: Timing cached reads: 90 MB in 2.05 seconds = 43.96 MB/sec Timing buffered disk reads: 24 MB in 3.11 seconds = 7.72 MB/sec So as you can see, it takes forever to something as simple as an apt-get upgrade and even logging into the server. How do I go about troubleshooting what is causing this? I upgraded the firmware on the PERC 6i RAID controller to the latest, but didn't see any improvements.

• MX record configuration for hosted email?

  - by Paul Sanwald

  I am helping a friend with his website, and am having a problem with his webmail configuration, which I suspect is due to a misconfigured MX record. His domain is registered and hosted by hostmonster, they have a webmail option. A record: Host Points To TTL webmail 12.345.789.101 14400 CNAME: mail webmail.d.com 14400 MX Record: 0 @ mail.d.com 14400 I've created an email account on hostmonster, [email protected]: however, when I sent an email to this account, it appears to be routing to /dev/null. I know that it's not actually, but am unsure of the steps I can take to track this down? I've tried using dig, but am unsure where to start. How can I track down where this email is being routed to?

• raspberry pi for web programming/development

  - by Mark Dee

  I'm into web development and my machine (AMD Phenom II, 8G RAM) is running Ubuntu 13.04. I love my current setup but I kinda miss some of Windows software like MSOffice or Adobe suites, and running on Virtualbox doesn't feel as snappy for me.... So I'm thinking of buying a new cheap machine where I would install Linux and do my development work there and have my current machine run Windows. I just found this thing called Raspberry pi which is really cheap and requires 12v only (I think) which makes it good for downloading stuff overnight. So, does it make sense to buy Raspberry pi, make it my primary dev machine, Windows being the secondary (for Adobe and browser testing of course)? Basically, I want to know if Raspberry pi meets the following requirements: It should run ArchLinux Sublime Text 3 python ruby nginx nodejs Deluge or Transmission (well, maybe just those, no need for videos and music players)
