• Redirecting or routing all traffic to OpenVPN on a Mac OS X client

  - by sdr56p

  I have configured an OpenVPN (2.2.1) server on an Ubuntu virtual machine in the Amazon elastic compute cloud. The server is up and running. I have installed OpenVPN (2.2.1) on a Mac OS X (10.8.2) client and I am using the openvpn2 binary to connect (in opposition to other clients like Tunnelblick or Viscosity). I can connect with the client and successfully ping or ssh the server through the tunnel. However, I can't redirect all internet traffic through the VPN even if I use the push "redirect-gateway def1 bypass-dhcp" option in the server.conf configurations. When I connect to the server with these configurations, I get a successful connection, but then an infinite series of error messages: "write UDPv4: No route to host (code=65)". Traffic routing seems to be compromised because I am not able to access anything anymore, not even the OpenVPN server (by pinging 10.8.0.1 for instance). This is beyond me. I am finding little help on the web and don't know what to try next. I don't think it is a problem of forwarding the traffic on the server since, first, I have also took care of that and, second, I can't even ping the VPN server locally through the tunnel (or ping anything at all for that matter). Thank you for your help. Here is the server.conf. file: port 1194 proto udp dev tun ca ca.crt cert ec2-server.crt key ec2-server.key # This file should be kept secret dh dh1024.pem server 10.8.0.0 255.255.255.0

• Apache using 100% CPU, once again

  - by CBenni

  Recently, apache2 started using 100% of CPU power: top gives me From other, similar threads, I took the tip to use mod_status. Aside from HUGE amounts of NULL requests, it gives: CPU Usage: u2.16 s1.32 cu0 cs0 - .0835% CPU load 1.2 requests/sec - 17.6 kB/second - 14.6 kB/request 8 requests currently being processed, 42 idle workers The access and error logs do not show anything surprising or intriguing at all. Note the .8% CPU usage. Another tip was to use strace: root@server:~# strace -p 1956 Process 1956 attached - interrupt to quit restart_syscall(<... resuming interrupted call ...> And remains like this for at least half an hour, without producing any additional output. Restarting apache fixed the problem for less than a second The server runs a few custom python scripts aswell as a django-powered website on apache2 (up-to-date), but even turning the scripts off (or not having them active in the first place) did not change anything. After I stopped apache and powered my server off, powered it on a few minutes afterwards and restarted all my services, the CPU usage remained low for several hours, just in order to pop up again randomly (?) The DigitalOcean CPU stats on my server are: You can see how the CPU usage was super high for almost half a day until I restarted the bot - just to remain stable for several hours and then pop up again. I am completely at a loss of words and don't know what I could do to find out what piece of my code is giving me these problems or if apache itself is the cause... Therefore I would greatly appreciate any hints to the questions: What else can I try to do? Which things might I not have checked? Is this definitely in my own code? How do you find what part of python code crashes an app via a infinite loop or similar?

• iptables rule on INPUT between 2 ethernet cards on the same host

  - by user1495181

  I have 2 eth cards on the same host. Both connected directly with LAN cable. I set eth0 with ip - 192.168.1.2 I set eth1 with ip - 192.168.1.1 I set this rule: iptables -A INPUT -p tcp -j NFQUEUE --queue-num 0 There are no other rules. (I ran iptables -X,-F) I send TCP syn packet ( with c++ program by using raw socket) from 192.168.1.2 to 192.168.1.1 In wireshark i see that the packet received on eth0, but the iptables rule (above) dosnt apply for this packet. when i sent the packet to remote host and apply this rule on the remote host than it work correct. So, i guess that this is due to the fact that both eth cards exists the same host. . I need to create iptables INPUT rule for local eth card (dest and src on the same machine ). I need it for simplify test. Did i guess the problem correct? is there a way to bypass this? Ps - connected them via switch didn't help. the rule wasn't applied. Run on Ubuntu. TCDUMP show the packet: 10:48:42.365002 IP 192.168.1.2.38550 > 192.168.1.1.34298: Flags [S], seq 0, win 5840, length 0 but logging of iptables like this, has nothing: iptables -A INPUT -p tcp -j LOG --log-prefix '*****************' iptables -A OUTPUT -p tcp -j LOG --log-prefix '#################'

• Assembling Software RAID in Live CD for data recovery

  - by Maletor

  I need help recovering some data that's on my RAID which is on a LVM on my server running Ubuntu. What happened was I deleted the logical volume that controlled my swap space which was on a partition on drives sda2, sdb2, sdc2, and sdd2 in RAID1. This foobared my whole system for one reason or another. Booting leave me with grub rescue and an error saying that it is an unknown filesystem. When I boot to a live cd I can see my RAID arrays and I can even start them up. However, it doesn't appear to mount them anywhere so I can't see the data. I am in the live cd now and I have done sudo apt-get install mdadm lvm2 so it should be mounting them correctly. I just can't see why it wouldn't. Please any help is appreciated here. Here is some output. By the way, there are 3 RAIDs, 1) /boot 100mb RAID1, 2) swap 10gb RAID1, 3) root 990GB RAID5 ubuntu@ubuntu:~$ df -h Filesystem Size Used Avail Use% Mounted on aufs 124M 101M 18M 86% / none 2.0G 324K 2.0G 1% /dev /dev/sde1 2.0G 826M 1.2G 42% /cdrom /dev/loop0 667M 667M 0 100% /rofs none 2.0G 164K 2.0G 1% /dev/shm tmpfs 2.0G 28K 2.0G 1% /tmp none 2.0G 92K 2.0G 1% /var/run none 2.0G 0 2.0G 0% /var/lock none 2.0G 0 2.0G 0% /lib/init/rw /dev/md1 91M 73M 15M 84% /media/5ac3dbf1-a6c5-409c-96ae-edc6e27992c7 ubuntu@ubuntu:~$ cat /etc/fstab aufs / aufs rw 0 0 tmpfs /tmp tmpfs nosuid,nodev 0 0 /dev/sda2 swap swap defaults 0 0 /dev/sdb2 swap swap defaults 0 0 /dev/sdc2 swap swap defaults 0 0 /dev/sdd2 swap swap defaults 0 0

• Constant crashes in windows 7 64bit when playing games

  - by yx.

  I've tried everything I can possibly think of in trying to fix this problem and I'm totally out of ideas, so any help would be appreciated: The problem: whenever I fire up a game, it works for a short while with no problems and then it would crash. Either its a hard crash, forcing me to reboot, or windows would report that the display driver has stopped working and recovered. Here is a list of things I've already tried: Drivers - tried the latest drivers (catalyst 9.12) as well as the stock drivers that came with the video card. Also have the latest BIOS/chipset Memtest - Ran Memtest86+ overnight, had no problems, the windows diagnostic tool also does not find any problems. Overheating - Video card/cpu temperatures are well below peak (42 and 31 Celsius receptively) PSU Voltage - CPUID shows that the voltage levels are all above what they should be. The PSU itself is only roughly 16 months old and is a good model. HDD - No errors when checked GPU - Brand new (replaced previous card since I thought it was the problem, apparently not) Overclocking - Everything is at stock levels, memory voltage is set to manufacturer's standard Specs: Motherboard: ASUS P5Q Pro CPU: Core 2 Duo E8400 3.0 ghz OS: Windows 7 home premium 64 bit Memory: Mushkin Enhanced 4GB DDR2 GPU: Sapphire HD 5850 1GB PSU: SeaSonic M12 600W ATX12V DirectX: DX11 Event Viewer after a crash always has these logged: A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 1 The details view of this entry contains further information. A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 0 The details view of this entry contains further information. A previous card that I had (4850x2) also had these errors, so I changed video cards, but the same thing is happening.

• How to find out which process is hogging the linux server?

  - by user1149518

  We have a RHEL server. Today it suddenly became slow. Symptoms - It was responding slow to ping queries from other server. When I try to login using ssh, it was taking about 10 seconds to login. I was able to resolve the problem by doing some guess work. I killed one process which I thought was culprit. Which resolved the problem.

• java memory allocation under linux

  - by pstanton

  I'm running 4 java processes with the following command: java -Xmx256m -jar ... and the system has 8Gb memory under fedora 12. however it is apparently going into swap. how can that be if 4 x 256m = 1Gb ? EDIT: also, how can all 8Gb of memory be used with so little memory allocated to basically the only thing running? is it java not garbage collecting because the OS tells it it doesn't need to or what?

• Using u32 together with extension headers (how to jump over them?)

  - by bortzmeyer

  I'm trying to filter on some parts of the payload, for an IPv6 packet with extension headers (for instance Destination Options). ip6tables works fine with conditions like --proto udp or --dport 109, even when the packet has extension headers. Netfilter clearly knows how to jump over Destination Options to find the UDP header. Now, I would like to use the u32 module to match a byte in the payload (say "I want the third byte of the payload to be 42). If the packet has no extension headers something like --u32 "48&0x0000ff00=0x2800"` (48 = 40 bytes for the IPv6 header + 8 for the UDP header) works fine, If the packet has a Destination Options, it no longer matches. I would like to write a rule that will work whether the packet has Destination Options or not. I do not find a way to tell Netfilter to parse until the UDP header (something that it is able to do, otherwise --dport 109 would not work) then to leave u32 parse the rest. I'm looking for a simple way, otherwise, as BatchyX mentions, I could write a kernel module doing what I want.

  I am making a WPF Application in C# where I need to show the recent documents history (just like it happens in word, excel and even visual studio), showing the list the last 5 or 10 documents opened. I have absolutely no idea as to how I should go about it. Please help. And please be kind and gentle...I am an amatuer coder, and it is tough to digest high-tech talks as of now! :)

• Control third check box based on the state of the first two using jquery

  - by Moj

  I have three check boxes and need to disable the third if either and/or of the other two are checked. I'm sure there's a easier way than what I have currently. It's turning into what I believe is a mess and I'm hoping that someone with more jquery knowledge can shine the light here. Here's my simple html form: <html> <head> <script type="text/javascript" src="jquery.js"></script> <script src="custom.js" type="text/javascript"></script> </head> <body> <input type="checkbox" class="class" id="1">First <input type="checkbox" class="class" id="2">Second <input type="checkbox" class="class" id="3">Third </body> </html> Here's the javascript I'm using with jquery v1.4.2 jQuery(document).ready(function() { // watches the events of all checkboxes $(":checkbox").click(function(){ if( // if both 1 and 2 are checked we don't want to enable Third until both are unchecked. (($('#1:checkbox').attr('checked'))&&($('#2:checkbox').attr('checked')))|| ((($('#1:checkbox').attr('checked'))&&($('#2:checkbox').attr('checked')))&&($('#3:checkbox').attr('disabled')))|| ((($('#1:checkbox').attr('checked'))||($('#2:checkbox').attr('checked')))&&($('#3:checkbox').attr('disabled'))) ){ // we don't want to do anything in the above events } else if( // handles the First check box (($('#1:checkbox').attr('checked'))||(!$('#1:checkbox').attr('checked')))|| // handles the Second check box (($('#2:checkbox').attr('checked'))||(!$('#2:checkbox').attr('checked'))) ){ // call the disableThird function disableThird(); } }); // handles enabling and disabling the Third checkbox function disableThird(){ var $checkbox = $('#3:checkbox'); $checkbox.attr('disabled', !$checkbox.attr('disabled')); }; }); For some reason checking #3 will disable it's self. I don't understand why. This works, but one of the requirements is that a non programmer should be able to edit and maintain this. Ideally it'd be great if he could just add new check boxes to the html and it would work. The class for these are define and as far as I know can't be changed. The last check box in the list of check boxes will disable if any of the ones above are selected. Like wise if the last check box is selected, it will disable all the ones above it. I haven't even begun writing and testing that portion as this is quickly becoming too complicated for a non programmer to handle. I myself am more of a PHP coder than a js, let alone jquery, coder. Any help would be greatly appreciated.

• Drawing a texture with an alpha channel doesn't work -- draws black

  - by DevDevDev

  I am modifying GLPaint to use a different background, so in this case it is white. Anyway the existing stamp they are using assumes the background is black, so I made a new background with an alpha channel. When I draw on the canvas it is still black, what gives? When I actually draw, I just bind the texture and it works. Something is wrong in this initialization. Here is the photo - (id)initWithCoder:(NSCoder*)coder { CGImageRef brushImage; CGContextRef brushContext; GLubyte *brushData; size_t width, height; if (self = [super initWithCoder:coder]) { CAEAGLLayer *eaglLayer = (CAEAGLLayer *)self.layer; eaglLayer.opaque = YES; // In this application, we want to retain the EAGLDrawable contents after a call to presentRenderbuffer. eaglLayer.drawableProperties = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGBA8, kEAGLDrawablePropertyColorFormat, nil]; context = [[EAGLContext alloc] initWithAPI:kEAGLRenderingAPIOpenGLES1]; if (!context || ![EAGLContext setCurrentContext:context]) { [self release]; return nil; } // Create a texture from an image // First create a UIImage object from the data in a image file, and then extract the Core Graphics image brushImage = [UIImage imageNamed:@"test.png"].CGImage; // Get the width and height of the image width = CGImageGetWidth(brushImage); height = CGImageGetHeight(brushImage); // Texture dimensions must be a power of 2. If you write an application that allows users to supply an image, // you'll want to add code that checks the dimensions and takes appropriate action if they are not a power of 2. // Make sure the image exists if(brushImage) { brushData = (GLubyte *) calloc(width * height * 4, sizeof(GLubyte)); brushContext = CGBitmapContextCreate(brushData, width, width, 8, width * 4, CGImageGetColorSpace(brushImage), kCGImageAlphaPremultipliedLast); CGContextDrawImage(brushContext, CGRectMake(0.0, 0.0, (CGFloat)width, (CGFloat)height), brushImage); CGContextRelease(brushContext); glGenTextures(1, &brushTexture); glBindTexture(GL_TEXTURE_2D, brushTexture); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, brushData); free(brushData); } //Set up OpenGL states glMatrixMode(GL_PROJECTION); CGRect frame = self.bounds; glOrthof(0, frame.size.width, 0, frame.size.height, -1, 1); glViewport(0, 0, frame.size.width, frame.size.height); glMatrixMode(GL_MODELVIEW); glDisable(GL_DITHER); glEnable(GL_TEXTURE_2D); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_DST_ALPHA); glEnable(GL_POINT_SPRITE_OES); glTexEnvf(GL_POINT_SPRITE_OES, GL_COORD_REPLACE_OES, GL_TRUE); glPointSize(width / kBrushScale); } return self; }

• Why use VB.Net instead C#?

• What defines writing PHP?

  - by cdburgess

  When writing PHP code for any given project, do you find you can write code off the top of your head? Or do you make multiple round trips to php.net? If it is the later, can you still be considered a good coder. This is a legitimate question as I find I have difficulty always remembering all of the functions that are available to me so I find I use php.net as a crutch. Is there anyway to improve this?

• Interesting C projects that upgraded your skill level.

  I've been (thus far) unable to write a project in C that would be meaningful on any level. For a first project, I've thought of many, but done none. What was the project that changed your skill-level from noob to "coder" the most? Maybe I can take some tips and work on something similar? I was thinking of a toy language, but well, I wouldn't know how to go about that. This might be closed, but oh well :)
