• Accessing guests on virtual network when connected to host via PPTP

  - by Viktor Elofsson

  I'm setting up a development machine which runs Ubuntu 12.04 and KVM for virtualization. I have a guest running Ubuntu 12.04 which can be accessed from the host via its IP address which is assigned by libvirt. The guest can also access the internet, no problem there. However, now I want to setup PPTP so I can connect to the host (from my workstation running Windows 7) and directly access guests without relying on SSH port forwarding. I can connect from my W7-machine to the host (PPTP), but I cannot access any virtual machines (which are accessable from the host directly). Relevant configuration files cat /etc/network/interfaces auto lo iface lo inet loopback # device: eth0 auto eth0 iface eth0 inet static address x.x.x.x broadcast x.x.x.x netmask x.x.x.x gateway x.x.x.x # default route to access subnet up route add -net x.x.x.x netmask x.x.x.x gw x.x.x.x eth0 virsh net-edit default <network> <name>default</name> <uuid>xxxxxxxx-72ce-3c20-af0f-d3a010f1bef0</uuid> <forward mode='nat'/> <bridge name='virbr0' stp='on' delay='0' /> <mac address='52:54:00:xx:xx:xx'/> <ip address='192.168.122.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.122.2' end='192.168.122.254' /> <host mac='52:54:00:yy:yy:yy' name='web1' ip='192.168.122.11' /> </dhcp> </ip> </network> cat /etc/pptpd.conf (commented lines removed) # TAG: option # Specifies the location of the PPP options file. # By default PPP looks in '/etc/ppp/options' # option /etc/ppp/pptpd-options # TAG: logwtmp # Use wtmp(5) to record client connections and disconnections. # logwtmp #(Recommended) localip 192.168.122.1 remoteip 192.168.122.234-238,192.168.122.245 cat /etc/ppp/chap-secrets* # Secrets for authentication using CHAP # client server secret IP addresses xxxxx * yyyyyyyyyy 192.168.122.100 I get the correct IP address when connecting my W7-machine, but when I try to ping the virtual machine at 192.168.122.11 I get Reply from 192.168.122.1: Destination port unreachable. It's probably something trivial I'm missing but I can't for the life of me figure out what it is. So I'm turning to you, serverfault.

• Print driver installs failing

  - by Kasius

  All of the Windows 7 64-bit Enterprise machines in my organization are failing to install a good number of printer drivers that previously installed without issue. This only happens with printer drivers. And not with all printer drivers. Just some. Network drivers, video drivers, etc. have had no problems. Here is part of setupapi.dev.log for a Dymo LabelWriter printer driver that is failing to install: dvi: {Plug and Play Service: Device Install for USBPRINT\DYMOLABELWRITER_450_TURBO\6&538F51D&0&USB001} ump: Creating Install Process: DrvInst.exe 09:36:58.071 ndv: Infpath=C:\Windows\INF\oem0.inf ndv: DriverNodeName=dymo.inf:DYMO.NTamd64.6.0:LW_450_TURBO_VISTA:8.1.0.363:usbprint\dymolabelwriter_450_aa08 ndv: DriverStorepath=C:\Windows\System32\DriverStore\FileRepository\dymo.inf_amd64_neutral_3a631b118b7a5828\dymo.inf ndv: Building driver list from driver node strong name... dvi: Searching for hardware ID(s): dvi: usbprint\dymolabelwriter_450_aa08 dvi: dymolabelwriter_450_aa08 inf: Opened PNF: 'C:\Windows\System32\DriverStore\FileRepository\dymo.inf_amd64_neutral_3a631b118b7a5828\dymo.inf' ([strings]) dvi: Selected driver installs from section [LW_450_TURBO_VISTA] in 'c:\windows\system32\driverstore\filerepository\dymo.inf_amd64_neutral_3a631b118b7a5828\dymo.inf'. dvi: Class GUID of device changed to: {4d36e979-e325-11ce-bfc1-08002be10318}. dvi: Set selected driver complete. ndv: {Core Device Install} 09:36:58.133 inf: Opened INF: 'C:\Windows\INF\oem0.inf' ([strings]) inf: Saved PNF: 'C:\Windows\INF\oem0.PNF' (Language = 0409) dvi: {DIF_ALLOW_INSTALL} 09:36:58.164 dvi: Using exported function 'ClassInstall32' in module 'C:\Windows\system32\ntprint.dll'. dvi: Class installer == ntprint.dll,ClassInstall32 dvi: No CoInstallers found dvi: Class installer: Enter 09:36:58.164 dvi: Class installer: Exit dvi: Default installer: Enter 09:36:58.180 dvi: Default installer: Exit dvi: {DIF_ALLOW_INSTALL - exit(0xe000020e)} 09:36:58.180 ndv: Installing files... dvi: {DIF_INSTALLDEVICEFILES} 09:36:58.180 dvi: Class installer: Enter 09:36:58.180 inf: Opened INF: 'C:\Windows\System32\DriverStore\FileRepository\dymo.inf_amd64_neutral_3a631b118b7a5828\dymo.inf' ([strings]) inf: Opened INF: 'C:\Windows\System32\DriverStore\FileRepository\dymo.inf_amd64_neutral_3a631b118b7a5828\dymo.inf' ([strings]) !!! dvi: Class installer: failed(0x00000490)! !!! dvi: Error 1168: Element not found. dvi: {DIF_INSTALLDEVICEFILES - exit(0x00000490)} 09:37:22.063 ndv: Device install status=0x00000490 ndv: Performing device install final cleanup... ! ndv: Queueing up error report since device installation failed... ndv: {Core Device Install - exit(0x00000490)} 09:37:22.063 dvi: {DIF_DESTROYPRIVATEDATA} 09:37:22.063 dvi: Class installer: Enter 09:37:22.063 dvi: Class installer: Exit dvi: Default installer: Enter 09:37:22.063 dvi: Default installer: Exit dvi: {DIF_DESTROYPRIVATEDATA - exit(0xe000020e)} 09:37:22.063 ump: Server install process exited with code 0x00000490 09:37:22.063 ump: {Plug and Play Service: Device Install exit(00000490)} Notice these lines in particular: !!! dvi: Class installer: failed(0x00000490)! !!! dvi: Error 1168: Element not found. dvi: {DIF_INSTALLDEVICEFILES - exit(0x00000490)} 09:37:22.063 ndv: Device install status=0x00000490 From what I have read, the "Element not found" error should be accompanied by an event describing what element was not found.

If I take it off the domain, it installs fine. But it doesn't seem to have anything to do with Group Policy. I moved the machine to an OU that blocks inheritance, ran a gpupdate, ran rsop.msc to verify, and tried again. And it still didn't work. Likewise, I removed a machine from the domain, manually set all of the domain Group Policy settings in gpedit.msc, and tried that way, and it worked fine. So it seems like the Group Policy settings are irrelevant. What other domain-related issue could be causing this though? Any ideas on what to try next would be greatly appreciated. I'm not sure where to go from here. Thanks!

• Puppet - Possible to use software design patterns in modules?

  - by Mike Purcell

  As I work with puppet, I find myself wanting to automate more complex setups, for example vhosts for X number of websites. As my puppet manifests get more complex I find it difficult to apply the DRY (don't repeat yourself) principle. Below is a simplified snippet of what I am after, but doesn't work because puppet throws various errors depending up whether I use classes or defines. I'd like to get some feed back from some seasoned puppetmasters on how they might approach this solution. # site.pp import 'nodes' # nodes.pp node nodes_dev { $service_env = 'dev' } node nodes_prod { $service_env = 'prod' } import 'nodes/dev' import 'nodes/prod' # nodes/dev.pp node 'service1.ownij.lan' inherits nodes_dev { httpd::vhost::package::site { 'foo': } httpd::vhost::package::site { 'bar': } } # modules/vhost/package.pp class httpd::vhost::package { class manage($port) { # More complex stuff goes here like ensuring that conf paths and uris exist # As well as log files, which is I why I want to do the work once and use many notify { $service_env: } notify { $port: } } define site { case $name { 'foo': { class 'httpd::vhost::package::manage': port => 20000 } } 'bar': { class 'httpd::vhost::package::manage': port => 20001 } } } } } That code snippet gives me a Duplicate declaration: Class[Httpd::Vhost::Package::Manage] error, and if I switch the manage class to a define, and attempt to access a global or pass in a variable common to both foo and bar, I get a Duplicate declaration: Notify[dev] error. Any suggestions how I can implement the DRY principle and still get puppet to work? -- UPDATE -- I'm still having a problem trying to ensure that some of my vhosts, which may share a parent directory, are setup correctly. Something like this: node 'service1.ownij.lan' inherits nodes_dev { httpd::vhost::package::site { 'foo_sitea': } httpd::vhost::package::site { 'foo_siteb': } httpd::vhost::package::site { 'bar': } } What I need to happen is that sitea and siteb have the same parent "foo" folder. The problem I am having is when I call a define to ensure the "foo" folder exists. Below is the site define as I have it, hopefully it will make sense what I am trying to accomplish. class httpd::vhost::package { File { owner => root, group => root, mode => 0660 } define site() { $app_parts = split($name, '[_]') $app_primary = $app_parts[0] if ($app_parts[1] == '') { $tpl_path_partial_app = "${app_primary}" $app_sub = '' } else { $tpl_path_partial_app = "${app_primary}/${app_parts[1]}" $app_sub = $app_parts[1] } include httpd::vhost::log::base httpd::vhost::log::app { $name: app_primary => $app_primary, app_sub => $app_sub } } } class httpd::vhost::log { class base { $paths = [ '/tmp', '/tmp/var', '/tmp/var/log', '/tmp/var/log/httpd', "/tmp/var/log/httpd/${service_env}" ] file { $paths: ensure => directory } } define app($app_primary, $app_sub) { $paths = [ "/tmp/var/log/httpd/${service_env}/${app_primary}", "/tmp/var/log/httpd/${service_env}/${app_primary}/${app_sub}" ] file { $paths: ensure => directory } } } The include httpd::vhost::log::base works fine, because it is "included", which means it is only implemented once, even though site is called multiple times. The error I am getting is: Duplicate declaration: File[/tmp/var/log/httpd/dev/foo]. I looked into using exec, but not sure this is the correct route, surely others have had to deal with this before and any insight is appreciated as I have been grappling with this for a few weeks. Thanks.

• Network Bridging for WiFi-to-Ethernet in linux

  - by shakaran

  It is possible Network Bridging for WiFi-to-Ethernet in linux instead of Ethernet-to-Ethernet? I have a CentOS 6.3 machine. I am using KVM and I want perform a brigde for virtualize more machines. This machine is connected only via wireless connection and it doesn't have a ethernet connection. So, I did a bridge over the WiFi interface like: # cat /etc/sysconfig/network-scripts/ifcfg-br0 DEVICE="br0" NM_CONTROLLED="yes" ONBOOT=yes TYPE=Bridge BOOTPROTO=none IPADDR=192.168.1.50 PREFIX=24 GATEWAY=192.168.1.1 DNS1=8.8.8.8 DNS2=8.8.4.4 DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System br0" Then I edit my wireless conection like: # cat /etc/sysconfig/network-scripts/ifcfg-mywireless ESSID="mywireless" MODE=Managed KEY_MGMT=WPA-PSK WPA_ALLOW_WPA2=yes CIPHER_PAIRWISE=CCMP CIPHER_GROUP=CCMP TYPE=Wireless #BOOTPROTO=none #IPADDR=192.168.1.50 #PREFIX=24 #GATEWAY=192.168.1.1 #DNS1=8.8.8.8 #DNS2=8.8.4.4 DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="Auto mywireless" UUID=874***** ONBOOT=yes LAST_CONNECT=1355923469 BRIDGE=br0 After, I restart the network: # /etc/init.d/network restart Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface Auto_mywireless: Error: Unknown connection: 874***** [FAILED] Bringing up interface br0: [ OK ] But as you can see, it show a error. My ifconfig output shows now: # ifconfig br0 Link encap:Ethernet HWaddr 6E:20:AD:CE:D8:AB inet addr:192.168.1.50 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::6c20:adff:fece:d8ab/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:67 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:6393 (6.2 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:432 errors:0 dropped:0 overruns:0 frame:0 TX packets:432 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:62433 (60.9 KiB) TX bytes:62433 (60.9 KiB) ra0 Link encap:Ethernet HWaddr 00:22:F7:2B:87:E5 inet addr:192.168.1.42 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::222:f7ff:fe2b:87e5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:46 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:487894880 (465.2 MiB) TX bytes:148136473 (141.2 MiB) virbr0 Link encap:Ethernet HWaddr 52:54:00:5B:30:9A inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:70 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:5838 (5.7 KiB) But this doesn't give internet connection and I loss access to 192.168.1.50. So, it is possible setup this networking bridge WiFi-to-Ethernet?

• Customizing Fantacy Remote .INI file

  - by karthik

  I am using Fantacy Remote to remote view other machines. I have attached the default .INI file that Fantacy Remote uses. When i connect to a machine, the client user should not have mouse and keyboard access of the Remote machine. It should be a View only remote connection. And i want to make the Remote viewer screen to be in full screen mode, because i dont want the user to do anything with menubars of Fatancy remote. Because this is kiosk application. What should i change in configuration file [.ini] inorder to achieve the above ? Anyone who have used this software before, kindly help..

• Optimal setup for ASUS P6X58D Premium BIOS (no OC)?

  - by rumtscho

  Normally, I'd trust the mainboard manufacturer to choose the best options as defaults. But I had trouble with the board, because even with Quick Boot enabled, it booted twice as slowly as a Pentium 4 Celeron. Then I changed lots of options at once (most of them weren't explained in the manual, just mentioned with a single sentence) and the boot time is only marginally worse than the Pentium 4 (54 sec against 46 sec from button to pw entering screen). Now I don't know if I have turned something off which should have stayed on. I guess I even won't be able to boot from a CD now, because even though it is present in the boot sequence, I took off a timeout I think it needs to check whether there is a disk in the drive. The second reason is that I don't have an internal HDD, only a SSD. I forgot my sources blush but I am under the impression that today's BIOS and OS options are geared toward booting from a HDD, which is often less than optimal when one boots from a SSD, especially when there are functions which cause avoidable writing cycles, as a SSD wears out after too many writing cycles. Most of the things I've read concern the OS, but there are some BIOS-relevant options too. I am especially confused about the disk mode. The board supports AHCI, IDE-simulation and RAID, but of the different articles I've read, there is a proponent for each and no clear arguments for any. So can one tell me which options are important in general and which are important for a SSD-only system? I don't want to overclock the CPU, so you don't have to say anything about this (yes I know the board is meant for OC:)). I am thinking of overclocking the RAM, since they sold me 1600er heatsinked modules which are running at 1066 now, but I'm not sure yet about that. The rest of the system: i7-930, Intel X25-m G2, 6 GB RAM, GTS 250, some no-name Blue-ray ROM. 2 external HDDs over USB 2.0. Lots of other USB-connected hardware (12 devices I think), no SATA 3 drives (will disabling the controller have an impact on performance?), no LAN, only WiFi. Lucid Lynx 64 bit, no dual boot, no virtual installations. The main uses of the system are: managing and playing/showing all the media stored on the external disks, lots of image manipulation, some video editing, a bit of (non-demanding) gaming, rarely development. Lots of Internet surfing too, but this shouldn't have much impact on performance.

• Three ways to upload/post/convert iMovie to YouTube [closed]

  - by alexyu2010

  For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.

• What the hell was THAT?!?

  - by Massimo

  My system is Windows XP SP3, updated with the latest patches. The PC is connected to a Cisco 877 ADSL router, which does NAT from the internal network to its single static public IP address. There are no forwarded ports, and the router's management console can only be accessed from the inside. I was doing two things: working on a remote office machine via VPN and browsing some web pages on the Cisco web site. The remote network is absolutely safe (it's a lab network, four virtual servers, no publicly accessible services and no users at all; also, none of what I'm going to describe ever happened there). The Cisco web site... well, I suppose is quite safe, too. Suddenly, something happened. Strange popups appears anywhere; programs claiming they're "antimalware", "antispyware" et so on begins autoinstalling; fake Windows Update and Security Center icons pop up in the system tray. svchost.exe began crashing repeatedly. Then, finally, after some minutes of this... BSOD. And, upon rebooting, BSOD again. Even in safe mode. Ok, that was obviously some virus/trojan/whatever. I had to install a new copy of Windows on another partition to clean things up. I found strange executables, services and DLLs almost anywhere. Amongst the other things, user32.dll and ndis.sys had been replaced. A fake software called "Antimalware Doctor" had been installed. There were services with completely random names or even GUIDs (!), and also ones called "IpSect" and "Darkness". There were executable files without an .exe extension. There were even two boot-class drivers, which I'm quite sure are the ones that finally caused the system to crash. A true massacre. Ok, now the questions: What the hell was that?!? It was something more than a simple virus! How did it manage to attack my computer, as I am behind a firewall and was not doing anything even only potentially harmful on the web at the time?

• How can I play my MP3 files through my stereo system?

  - by Joel Coehoorn

  Here's the situation. Like many others I have my entire CD collection ripped to my PC, along side other music I've acquired through iTunes or Amazon MP3. Also like many others the speakers at my PC are underpowered, and likely included in my monitor as an afterthought. This is fine for most use: system sounds, YouTube, etc. Even games sounds and music. But I'd like something a little better for when I really want to listen to music. And I have it; in the next room — barely 25 feet away as the crow flies — sits a nice 400 watts stereo system. The stereo supports MP3 CDs, so up to this point I've just kept a few CD-RW disks around to keep most of my collection available. But it's time to move on to something a little more sophisticated. What are my options for using the MP3 files available on my computer as an input for this stereo? Some notes: I want to be able to control what song the stereo is playing without having to go to the PC, including setting up and retrieving playlists. Ideally this should even be able to wake the PC from sleep mode to start playing. I primarily use Windows Media Player on the PC (which runs Windows Vista). However, the files themselves live on a server running Windows Server 2008, and so I could also install something on the server and run everything from there. The axillary input on the stereo is unfortunately limited to a 1/8 inch stereo mini-plug. I'm loath to run wires across two rooms, and I'm considering moving the stereo to the garage at some point. Therefore a wireless solution that can easily cover about 100 ft or so is preferred. I already have a Wi-Fi network ready, but it's secured so anything using Wi-Fi should make it easy to set up security. Bonus points for doing it in under $85 shipped at Amazon (I'm hoping to pay for this via $85 worth of Amazon gift cards). I know this a pretty tight budget, so just getting close is okay. Bonus points for something that remembers multiple profiles (keep my favorite songs separate from the wife's). Bonus points for a remote that can also replace my stereo remote, so I only need one device to control everything. I'm not holding my breath on this one given my price range, though. Bonus points if I can also use for Internet radio. Doing some research on my own as well. This looks like it'll do exactly what I want, but it lists at an outrageous $299: http://www.linksysbycisco.com/US/en/products/DMP100

• Fedora 13 post security update boot problem

  - by Alex

  Hello. About a month ago I installed a security update that had new Kernek 2.6.34.x from 2.6.33.x), this is when the problem occurred for the first time. After the install my computer would not boot at all, black screen without any visible hard drive activity (I gave it good 30 minutes on black screen, before took actions)... I poped in installation DVD and went in rescue mode to change back the boot option to old kernel (was just a guess where the problem was). After restart computer loaded just file, took a long time for it to start because of SELinux targeted policy relabel is required. Relabeling could take very long time depending on file size. I assumed that the update got messed up somehow and continued working with modified boot option. Couple of days ago, there was another kernel update. I installed it and same problem as before. This rules out corrupted update theory... Black screen right after 'BIOS' screen before OS gets loaded. I had to rescue system again... Below is copy of my grub.conf file. I am fairly new to LINUX (couple of years of experience), mostly development and basic config... nothing crazy. # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,0) # kernel /vmlinuz-version ro root=/dev/mapper/vg_obalyuk-lv_root # initrd /initrd-[generic-]version.img #boot=/dev/sda default=2 timeout=0 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title Fedora (2.6.34.6-54.fc13.i686.PAE) root (hd0,0) kernel /vmlinuz-2.6.34.6-54.fc13.i686.PAE ro root=/dev/mapper/vg_obalyuk-lv_root rd_LVM_LV=vg_obalyuk/lv_root rd_LVM_LV=vg_obalyuk/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us rhgb quiet initrd /initramfs-2.6.34.6-54.fc13.i686.PAE.img title Fedora (2.6.34.6-47.fc13.i686.PAE) root (hd0,0) kernel /vmlinuz-2.6.34.6-47.fc13.i686.PAE ro root=/dev/mapper/vg_obalyuk-lv_root rd_LVM_LV=vg_obalyuk/lv_root rd_LVM_LV=vg_obalyuk/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us rhgb quiet initrd /initramfs-2.6.34.6-47.fc13.i686.PAE.img title Fedora (2.6.33.8-149.fc13.i686.PAE) root (hd0,0) kernel /vmlinuz-2.6.33.8-149.fc13.i686.PAE ro root=/dev/mapper/vg_obalyuk-lv_root rd_LVM_LV=vg_obalyuk/lv_root rd_LVM_LV=vg_obalyuk/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us rhgb quiet initrd /initramfs-2.6.33.8-149.fc13.i686.PAE.img I like my system to be up to date... Let me know if I can post any other files that can be of help. Has anyone else had this problem? Does anyone has any ideas how to fix this problem? p.s. Anything helps, you ppl are great! thx for ur time.

• Trouble setting up PATH for Java on Debian

  - by milkmansrevenge

  I am trying to get Oracle Java 7 update 3 working correctly on Debian 6. I have downloaded and set up the files in /usr/java/jre1.7.0_03. I have also set the following two lines at the end of /etc/bash.bashrc: export JAVA_HOME=/usr/java/jre1.7.0_03 export PATH=$PATH:$JAVA_HOME/bin Logging in as other users and root is fine, Java can be found: chris@mc:~$ java -version java version "1.7.0_03" Java(TM) SE Runtime Environment (build 1.7.0_03-b04) Java HotSpot(TM) 64-Bit Server VM (build 22.1-b02, mixed mode) However there are two cases where Java cannot be found as detailed below. Note that both of these worked fine when I have previously installed OpenJDK Java 6 via aptitude, but I need Oracle Java 7 for various reasons. Most importantly, I cannot run commands as another user via su, despite the PATH showing that Java should be present. The user was created with adduser chris root@mc:~# su chris -c "echo $PATH" /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/java/jre1.7.0_03/bin:/bin root@mc:~# su chris -c "java -version" bash: java: command not found root@mc:~# su chris -c "/usr/java/jre1.7.0_03/bin/java -version" java version "1.7.0_03" ... How can it be in the PATH but not be found? Update 05/04/2012: explained by Daniel, to do with it being a non-interactive shell so files such as /etc/profile and /etc/bash.bashrc are not executed. Doing a full swap to that user and running Java works: root@mc:~# su chris chris@mc:/root$ java -version java version "1.7.0_03" ... I run a script on start up which exhibits similar but slightly different problems. The script is located in /etc/init.d/start-mystuff.sh and calls a jar: #!/bin/bash # /etc/init.d/start-mystuff.sh java -jar /opt/Mars.jar I can confirm that the script runs on start up and the exit code is 127, which indicates command not found. Inserting a line to print/save the PATH shows that it is: /sbin:/usr/sbin:/bin:/usr/bin This second problem isn't as important because I can just point directly to the Java executable in the script, but I am still curious! I have tried setting the full PATH and JAVA_HOME explicitly in /etc/environment which didn't help. I have also tried setting them in /etc/profile which doesn't seem to help either. I have tried logging in and out again after setting PATH in the various locations (duh!). Anyway, long post for what will probably have a simple one line solution :( Any help with this would be greatly appreciated, I have spent far too long trying to fix it by myself. Motivation The first problem may seem obscure but in my system I have users that are not allowed SSH access yet I still want to run processes as them. I have a ton of scripts operating in this way and don't want to have to change them all.

• Kickstart based installation of RHEL 6.4 from USB

  - by Peter

  I want to setup some brand new servers with RHEL 6.4. Servers do not have DVD, so, I have to use USB for the installation. I already have a custom ISO with a kickstart file that I use on servers with DVD flawlessly. I used iso2usb to move the ISO t? my USB. When I boot from the USB, the ks file is found, anaconda starts, but then stops with the following error: "The installation source given by device ['sda1'] could not be found. Please check your parameters and try again" Notes: The USB IS the sda. My custom ISO file is renamed to linux.iso from iso2usb and it is present in the root directory of the USB. Kickstart file has the following entry: harddrive --partition=sda1 --dir=/ Please help me to automate the installation with kickstart.

Some things i have tried so far: I think that i have some performance issues with one of the applications, Here you can see a threadDump But i'm not quite sure about it. I also started to monitor the network connection. I have noticed that there are some pings lost when i have a "ping -f " so maybe it could be a network issue, but the success rate is 100% (so the lost packets are only a few among the flood, but maybe, i don't know, enough to break the link betwen apache and tomcat). I wrote a python script to check connectivity with timestamps on the pings, so i can know when the network fails. After sniffing the network , i can also see some RST packets, but i don't know if that is a normal behaviour (some applications do that to end a network communication). I have also noticed that the applications have problems communicating with the database, but im not even sure if this could be related or not. If you think so, i can post more info about it. I changed the connector on the tomcats to use the native one, but still the same. I need not even a solution to this, but maybe some guidance on how can i troubleshoot this better ¿Analyze threads, monitor mysql performance, sniff the traffic between apaches and tomcats? Ultimately, all i need is to balance the tomcat instances in Active/pasive mode, so if there is another way to do it, i could give it a try.

• Having troubles connectiong Magento to external Windows Database Server using Windows Azure

  - by Kevin H

  "I tried to make this easy to read through" I am using Ubuntu 12.04 LTS for Magento and installed these commands onto the system: sudo apt-get install apache2 sudo apt-get install php5 libapache2-mod-php5 sudo apt-get install php5-mysql sudo apt-get install php5-curl php5-mcrypt php5-gd php5-common sudo apt-get install php5-gd I used Windows Server 2008 R2 August 2012 for Mysql Server For a reference, I used http://www.windowsazure.com/en-us/manage/windows/common-tasks/install-mysql/ When the server was setup, I added an empty disk to it Then, I added endpoints 3306 Next I accessed the server remotely After that, I formatted the empty disk and was inserted as F: Next I downloaded Mysql from http://*.mysql.com version Windows (x86, 64-bit), MSI Installer 5.5.28 In the installation process, I used these settings: Typical Setup - Clicked Next, install, next Chose Detailed Configuration - Clicked next Chose Dedicated MySQL Server Machine - Clicked Next Chose Transactional Database Only - Clicked Next Chose the "F:" Drive - Clicked Next Chose Online Transactional Processing (OLTP) - Clicked Next For Networking Options, I checkmarked 'Enable TCP/IP Networking" 'Add firewall exception for this port' 'Enable Strict Mode' - Clicked Next Chose Standard Character Set - Clicked Next For Windows Options, I checkedmarked 'Install as Window Service" 'Launch the MySQL Server automatically' 'Include Bin Directory in Windows PATH - Clicked Next For Security Options, I checkmarked 'Modify Security Settings' and set root password - Clicked Next Finally clicked Execute and Finish These are the Firewall Setting that I set I clicked inbound rules Properties Scope Allow IP Address and used the internal Address for Magento Server Clicked Apply and exited Next, I opened up MySQL 5.x Command Line Client Entered Root Password Then entered these commands mysql create database magento; mysql Create user magentouser identified by 'password'; mysql Grant select, insert, create, alter, update, delete, lock tables on magento.* to magentouser mysql exit Finally, I opened up the Magento Downloader Magento validation has approved all PHP version is right.

Also, I have tryed to setup mysql on independant Linux Server but kept getting errors. When, I found the solution. Wouldn't work, so I decided to try Windows. These is the questions, I have been asking and researching to debug this issue Is it because I am using Linux for magento and Windows for Database. I have had no luck in finding a reason why this wouldn't work There must be something, I am missing I also researched the difference between linux sql databases and windows sql databases but have not come to conclusion, if installing Mysql on windows would make a difference in syntax and coding. I have spent a lot of time looking into this and need some help with direction on how to complete my project. Any type of help would be appreciated.

• Small Business Server services will not start, and remote desktop and UAC are broken

  - by Stephen Jennings

  Yesterday I began setting up a server with Windows Small Business Server 2008. All I am configuring it for right now is to be a domain controller and Exchange server. I completed the initial setup of SBS then started looking through different connection options (allowing VPN versus using a TS Gateway). After I rebooted one time, I started having three not-obviously-related issues: First, I could no longer remote desktop into the computer. I ran TCPView and saw that it was no longer listening on port 3389. I checked everything in Terminal Service Configuration but everything shows the computer ought to be allowing connections. Also, when I tried to use anything that required user account control elevation, the UAC dialog never popped up and the program that was waiting just froze. If I try to run "regedit" from the Run box, for example, it never appears. When I run in safe mode which does not run with UAC, I was able to access everything. I didn't want to deal with it, so I turned off UAC and rebooted. Finally, in the Windows SBS Console, there are status indicators for Security, Updates, Backup, and Other Alerts. The first three get stuck saying "Querying". Looking in the computer alerts, I have events showing the following services stopped: Background Intelligent Transfer Service KtmRm for Distributed Transaction Coordinator Distributed Transaction Coordinator Microsoft Exchange Information Store Microsoft Exchange System Attendant Microsoft Exchange Transport Windows Remote Management Update Services Windows Update I figured I must have configured something wrong accidentally and I couldn't find anything using Google explaining what might be the case, so I just decided to format the hard drive and reinstall SBS from scratch. I did this and everything was working last night, but I just turned the machine back on and it is doing the same thing again! On my second install, I did not configure anything except the following (all from SBS Console): Connect to the Internet (set IP and router address) Turn off customer feedback. Set up internet address. Decline to use a Smart Host for email. Added one standard user account. Since this happened again and I was very careful the second time not to configure anything outside of the SBS Console, I feel like there's something else going on. Right now the machine is on an isolated network that does have internet access. My desktop is the only other machine plugged into this network. Any and all help is appreciated (before I tear my hair out!)

The screen that we have registers that it is connected to something (by not displaying the screen it does when the cable is unplugged) but just remains blank, no output at all. I recently took the card to my University and one of my friends who is better with hardware issues than I am tried it in his system and it worked perfectly. No issues whatsoever. I do not have a spec list for his system but I could get one if you need it. If you need any more information on this issue I will be happy to supply you with it as I am starting to get very annoyed with this problem ^_^

• Disable Acer eRecovery system

  - by Joel Coehoorn

  The meat of this question is that I'm looking for a way to either require a password before using a recovery partition or "break" the recovery partition (specifically, Acer eRecovery) in a way that I can later "unbreak" only by booting normally into windows first. Here's the full details: I have a set of new Acer Veriton n260g machines in a computer lab. A lot work went into setting up this lab to work well - for example, Office 2007 and other programs needed by the students were installed, all windows updates are applied, and a default desktop is setup. All in all it's several hours work to fully set up one machine. Unfortunately, I don't currently have the ability to easily image these machines, and even if I did I would want to avoid downtime even while an image is restored. Therefore, I've taken steps to lock them down — namely DeepFreeze and a bios password to prevent booting from anywhere but the frozen hard drive. DeepFreeze is an amazing product — as long as you boot from the frozen hard drive, there is no way to actually make permanent changes to that hard drive. Anything you do is wiped after the machine restarts. It lets me give students the leeway to do what they want on lab computers without worrying about them breaking something. The problem is that even with the bios locked and set to only boot from the hard drive, these Acers still have a simple way to choose a different boot source: shut them down and put a paper click in a little hole at the top while you turn it on again. This puts them into the "Acer eRecovery" mode. This by itself is no big deal — you can still power cycle with no impact. But if you then click through the menu to reset the machine (we're now past the point of curiosity and on to intent) it will wipe the hard drive and restore it to the original state. Of course, a few students have already figured this out and reset a couple machines. That's unfortunate, but inevitable. I don't want to destroy the ability to do this entirely (which I could by repartitioning the drives to remove the recovery partition) but I would like a way to require a password first, or "break" the recovery system in a way that I can "unbreak" only if I first un-freeze the hard drive in DeepFreeze. Any ideas?

• Kernel upgrade CentOS 5.3 mount: could not find filesystem '/dev/root'

  - by matt

  We have a CentOS 5.3 x64 server that by default runs kernel version 2.6.18-164.11.1 and we are attempting to upgrade the box to 2.6.31.12 The drive is LVM +ext3, and the problem I'm having is when I upgrade the kernel and attempt to boot from it, no matter what version of the kernel I use, I get /dev/root not found towards the end of the boot process, and the kernel panics, and than reboots. I'm installing the kernel exactly as it says in this doc. I've tried it "The centOS way " using make rpm and than installing that. I've updated my mkinitrd. The most interesting part of this problem is that it has been so frustrating that I decided to try and clean install centos on an identical machine without LVM, and the result is EXACTLY the same. After upgrading the kernel, I get /dev/root not found. Does anyone know how to fix this, or what information would be relevant to remedy it? I'm open to try anything at this point. One more interesting thing about this problem is that in the new version of the kernel, during boot it complains that dm-mapper is started twice, than panics right after that. I've tried this with other kernel versions, and the result is the same. What am I missing here? If you need any more files, please just ask. Linux cg 2.6.18-164.11.1.el5 #1 SMP Wed Jan 20 07:32:21 EST 2010 x86_64 x86_64 x86_64 GNU/Linux /dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 default=1 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.31.12-rt20) //NOT WORKING!!!! root (hd0,0) kernel /vmlinuz-2.6.31.12-rt20 ro root=/dev/VolGroup00/LogVol00 isolcpus=8,9,10,11,12,13,14,15 panic=10 initrd /initrd-2.6.31.12-rt20.img title CentOS (2.6.18-164.11.1.el5) //WORKING!! root (hd0,0) kernel /vmlinuz-2.6.18-164.11.1.el5 ro root=/dev/VolGroup00/LogVol00 isolcpus=8,9,10,11,12,13,14,15 panic=10 initrd /initrd-2.6.18-164.11.1.el5.img

• OpenLDAP with StartTLS broken on Debian Lenny

  - by mr.zog

  I'm trying to get OpenLDAP on Lenny to work with StartTLS. I have a Fedora 13 machine which I'm using as a client for testing. So far the Fedora client is ignoring the 'host' directive in /etc/ldap.conf when I try to connect using ldapsearch. The client wants to connect to 127.0.0.1:389 even if I specify -H ldaps://server.name on when using ldapsearch. /etc/ldap.conf on the client machine is in mode 444. But even when I try connecting locally from an ssh session, I see errors like this: ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1) Someone hit me with a cluebat, plz. Update: you must use ~/.ldaprc for settings such as 'host'. Also, I just used nmap against the ldap server and it showed 636 and 389 in an open state. Here's what prints to screen when I try to connect with, ldapsearch -ZZ –x '(objectclass=*)'+ -d -1 ldap_create ldap_extended_operation_s ldap_extended_operation ldap_send_initial_request ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP 192.168.10.41:636 ldap_new_socket: 3 ldap_prepare_socket: 3 ldap_connect_to_host: Trying 192.168.10.41:636 ldap_pvt_connect: fd: 3 tm: -1 async: 0 ldap_open_defconn: successful ldap_send_server_request ber_scanf fmt ({it) ber: ber_dump: buf=0x9bdbdb8 ptr=0x9bdbdb8 end=0x9bdbdd7 len=31 0000: 30 1d 02 01 01 77 18 80 16 31 2e 33 2e 36 2e 31 0....w...1.3.6.1 0010: 2e 34 2e 31 2e 31 34 36 36 2e 32 30 30 33 37 .4.1.1466.20037 ber_scanf fmt ({) ber: ber_dump: buf=0x9bdbdb8 ptr=0x9bdbdbd end=0x9bdbdd7 len=26 0000: 77 18 80 16 31 2e 33 2e 36 2e 31 2e 34 2e 31 2e w...1.3.6.1.4.1. 0010: 31 34 36 36 2e 32 30 30 33 37 1466.20037 ber_flush2: 31 bytes to sd 3 0000: 30 1d 02 01 01 77 18 80 16 31 2e 33 2e 36 2e 31 0....w...1.3.6.1 0010: 2e 34 2e 31 2e 31 34 36 36 2e 32 30 30 33 37 .4.1.1466.20037 ldap_write: want=31, written=31 0000: 30 1d 02 01 01 77 18 80 16 31 2e 33 2e 36 2e 31 0....w...1.3.6.1 0010: 2e 34 2e 31 2e 31 34 36 36 2e 32 30 30 33 37 .4.1.1466.20037 ldap_result ld 0x9bd3050 msgid 1 wait4msg ld 0x9bd3050 msgid 1 (infinite timeout) wait4msg continue ld 0x9bd3050 msgid 1 all 1 ** ld 0x9bd3050 Connections: * host: 192.168.10.41 port: 636 (default) refcnt: 2 status: Connected last used: Sun Jun 6 12:54:05 2010 ** ld 0x9bd3050 Outstanding Requests: * msgid 1, origid 1, status InProgress outstanding referrals 0, parent count 0 ld 0x9bd3050 request count 1 (abandoned 0) ** ld 0x9bd3050 Response Queue: Empty ld 0x9bd3050 response count 0 ldap_chkResponseList ld 0x9bd3050 msgid 1 all 1 ldap_chkResponseList returns ld 0x9bd3050 NULL ldap_int_select read1msg: ld 0x9bd3050 msgid 1 all 1 ber_get_next ldap_read: want=8, got=0 ber_get_next failed. ldap_err2string ldap_start_tls: Can't contact LDAP server (-1)

• Configuring gmail for use on mailing lists

  - by reemrevnivek

  This is really two questions in one. First, are nettiquette guidelines still accurate in their restrictions on ASCII vs. HTML, posting style, and line length? (Here's a recent metafilter discussion of the topic.) Second, If they are not, should these guidelines be respected? If they are (or if they should still be respected), how can modern mail programs be configured to work properly with them? Most mailing list etiquette statements appear to have been written by sysadmins who loved their command lines, and refuse to change anything. Many still reference rfc1855, written in 1995. Just reading that paginated TXT should give you an idea of the climate at the time. Here's a short, fairly random list of mailing list etiquette statements with some extracted formatting guidelines: Mozilla - HTML discouraged, interleaved posting. FreeBSD - No HTML, don't top post, line length at 75 characters. Fedora - No HTML, bottom-post. You get the idea. You've all seen etiquette statements before. So, assuming that the rules should be obeyed (Usually a good idea), what can be done to allow me to still use a modern mail program, and exchange mail with friends who use the same programs? We like to format our mail. Bold headings, code snippets (sometimes syntax highlighted, if the copy-paste pulls RTF text as from XCOde and Eclipse), free line breaks determined by your browser width, and the (very) occasional image make the message easier to read. Threaded conversations are a wonderful thing. Broadband connections are, I'm sure, the rule for most of the users of SU and of developer mailing lists, disk space is cheap, and so the overhead of HTML is laughable. However, I don't want to post a question to a mailing list and have the guru who can answer my question automatically delete it, or come off as uncaring. Until I hear otherwise, I'll continue to respect the rules as best I can. For a common example of the problem, Gmail, by default, sends HTML formatted messages with bottom-posted quotes (which are folded in, just read the last message immediately above), and uses the frame width to wrap lines, rather than a character count. ASCII can be selected, and quotes can be moved and reversed, but line wraps of quotes don't work, line breaks are tedious to add (and more tedious to read, if they're super small in comparison to the width of the frame). Is there a forwarding, free mail program which can help with this exercise? Should an "RFC1855 mode" lab be written? Or do I have to go to the command line for my mailing lists, and gmail for my other mail?

• lighttpd: weird behavior on multiple rewrite rule matches

  - by netmikey

  I have a 20-rewrite.conf for my php application looking like this: $HTTP["host"] =~ "www.mydomain.com" { url.rewrite-once += ( "^/(img|css)/.*" => "$0", ".*" => "/my_app.php" ) } I want to be able to put the webserver in kind of a "maintenance" mode while I update my application from scm. To do this, my idea was to enable an additional rewrite configuration file before this one. The 16-rewrite-maintenance.conf file looks like this: url.rewrite-once += ( "^/(img|css)/.*" => "$0", ".*" => "/maintenance_app.php" ) Now, on the maintenance page, I have a logo that doesn't get loaded. I get a 404 error. Lighttpd debug says the following: 2012-12-13 20:28:06: (response.c.300) -- splitting Request-URI 2012-12-13 20:28:06: (response.c.301) Request-URI : /img/content/logo.png 2012-12-13 20:28:06: (response.c.302) URI-scheme : http 2012-12-13 20:28:06: (response.c.303) URI-authority: localhost 2012-12-13 20:28:06: (response.c.304) URI-path : /img/content/logo.png 2012-12-13 20:28:06: (response.c.305) URI-query : 2012-12-13 20:28:06: (response.c.300) -- splitting Request-URI 2012-12-13 20:28:06: (response.c.301) Request-URI : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.302) URI-scheme : http 2012-12-13 20:28:06: (response.c.303) URI-authority: localhost 2012-12-13 20:28:06: (response.c.304) URI-path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.305) URI-query : 2012-12-13 20:28:06: (response.c.349) -- sanatising URI 2012-12-13 20:28:06: (response.c.350) URI-path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (mod_access.c.135) -- mod_access_uri_handler called 2012-12-13 20:28:06: (response.c.470) -- before doc_root 2012-12-13 20:28:06: (response.c.471) Doc-Root : /www 2012-12-13 20:28:06: (response.c.472) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.473) Path : 2012-12-13 20:28:06: (response.c.521) -- after doc_root 2012-12-13 20:28:06: (response.c.522) Doc-Root : /www 2012-12-13 20:28:06: (response.c.523) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.524) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.541) -- logical -> physical 2012-12-13 20:28:06: (response.c.542) Doc-Root : /www 2012-12-13 20:28:06: (response.c.543) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.544) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.561) -- handling physical path 2012-12-13 20:28:06: (response.c.562) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.618) -- file not found 2012-12-13 20:28:06: (response.c.619) Path : /www/img/content/logo.png, /img/content/logo.png Any clue on why lighttpd matches both rules (from my application rewrite config and from my maintenance rewrite config) and concatenates them with a comma - that doesn't seem to make any sense?! Shouldn't it stop after the first match with rewrite-once?

• possible UDP attack on BIND?

  - by Waleed Hamra

  hello everyone, i was surprised last month when my EC2 instance (ubuntu precise server), that is supposed to be under the free tier still, accumulated lots of traffic... today, while checking my current billing statement, i noticed i already have tons of traffic, while still in the middle of the month, and i'm fearing what my bill by the end of the month is going to be... i installed bandwidthd, and after few minutes, i noticed lots of UDP traffic to "108.162.233.15". this is apparently a cloudflare IP, and i don't have anything using cloudflare (as far as i know). so i ran "iftop" to see what ports are being used, and i saw the UDP traffic coming from port 80 to my port 53... why would a webserver query dns? so i stopped bind on my server, and ran it in foreground debugging mode, and saw the following query, being repeated continuously: 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: UDP request 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: request is not signed 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: recursion available 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: query 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: query (cache) 'isc.org/ANY/IN' approved 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: send 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: sendto 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: senddone 17-Nov-2012 12:30:58.217 client 108.162.233.15#80: next 17-Nov-2012 12:30:58.217 client 108.162.233.15#80: endrequest 17-Nov-2012 12:30:58.217 client @0x7fbee05126e0: udprecv 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: UDP request 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: request is not signed 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: recursion available 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: query 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: query (cache) 'isc.org/ANY/IN' approved 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: send 17-Nov-2012 12:30:58.344 client 108.162.233.15#80: sendto 17-Nov-2012 12:30:58.344 client 108.162.233.15#80: senddone 17-Nov-2012 12:30:58.344 client 108.162.233.15#80: next 17-Nov-2012 12:30:58.344 client 108.162.233.15#80: endrequest my question is... is this normal? should i be worried? or is this completely irrelevant to my data charges, and i should wait to see more data from bandwidthd? thank you in advance.
