• Two parts: linux startup script to connect to bluetooth and cron to keep it connected

  - by D.R.

  I have a mini bluetooth keyboard and a Raspberry Pi running a Debian-based distro. I know the MAC address of the keyboard but for this question, let's just use AA:BB:CC:DD:EE:FF. Right now I have to have a wired keyboard connected as well as my bluetooth dongle for the mini-keyboard and on the wired keyboard, I have to run the following when the device boots up: sudo hidd --connect AA:BB:CC:DD:EE:FF If the device goes idle for too long, then the bluetooth disconnects and I have to pull out my wired keyboard and retype that same command. What I'm looking for it a way to have that command run at startup and a way to sense if it gets disconnected so that it will auto reconnect. The annoying thing is that they keyboard has to be in pairing mode (even though it has already been paired) when I run that command, otherwise it tells me the host is down. So perhaps the script needs to prevent it from disconnecting due to inactivity, otherwise I'll have to put it back in pairing mode to reconnect. So to recap: - A script to connect at startup (I can make sure to put the keyboard into pairing mode before turning it on) - A script to prevent it from disconnecting (maybe some sort of signal to send to it every 60 seconds or something?) Any help with this is greatly appreciated! StackOverflow is always the best place to find answers to weird questions! I've been searching long and hard for an answer, but finally had to resort to coming here! Thanks!

• Setting up Windows network on Xen

  - by samyboy

  I'm trying to install a Windows XP server in a Xen environment. The OS is booting fine. Unfortunately I can't figure out how to set up the network settings. Dom0 is a Debian Lenny currently hosting around 10 Linux virtual servers. Windows tells me I have a "limited connection". It can't get any DHCP response, nor access other hosts in the network Here is the Xen's client config file: kernel = '/usr/lib/xen-3.2-1/boot/hvmloader' builder = 'hvm' memory = '1024' device_model='/usr/lib/xen-3.2-1/bin/qemu-dm' acpi=1 apic=1 pae=1 vcpus=1 name = 'winexchange' # Disks disk = [ 'phy:/dev/wnghosts/exchange-disk,ioemu:hda,w', 'file:/mnt/freespace/ISO/DVD1_Installation.iso,ioemu:hdc:cdrom,r' ] # Networking vif = [ 'mac=00:16:3E:0A:D0:1B, type=ioemu, bridge=xenbr0'] # video stdvga=0 serial='pty' ne2000=0 # Behaviour boot='c' sdl=0 # VNC vfb = [ 'type=vnc' ] vnc=1 vncdisplay=1 vncunused=1 usbdevice='tablet' Server config (/etc/xen/xend-config.sxp) (network-script network-bridge) (network-script network-dummy) (vif-script vif-bridge) (dom0-min-mem 512) (dom0-cpus 0) (vnc-listen '0.0.0.0') Since I use Debian I had to create a link like this: /etc/xen/qemu-ifup - /etc/xen/scripts/qemu-ifup What did I do wrong? Please tell me if you want some more info (logs, etc)

• Convert a cassette tape recording to digital format

  - by Optimal Solutions

  Has anyone been successful with transferring audio cassette tape recordings to a digital format? I would like to preserve old cassette tape recordings of my grandparents to some digital format: MP3, WAV, etc... The quality of the tapes are mediocre. I think I can handle the quality restoration but getting the audio from tape to digital is my question. Below is a list of the hardware that I can work with: Cassette Deck: I have a Technics stereo cassette deck model RS-B12. It has separate left and right IN and OUT RCA type jacks on the back. In the front it has a headphone phono jack, plus left and right mic input phono jacks. On the computer side: -I have a Windows Vista PC with no additional software other than what came with the machine from Costco. No sound editing software that I can see. There is no sound card on the PC. On the front panel there is a mini-phono mic input jack and there are several different types of in/out mini-phono jacks on the back. In addition, USB and Firewire. I also have access to a new (2009) iMac with a mini-phono input jack for a powered mic or other audio source and GarageBand that has come with the computer. In addition, USB and Firewire. What are my options for getting these cassette recordings into a digital format? Whats the best format? What sort of wires would I need and will I want to utilize the USB or Firewire or can I simply use the audio inputs on the PC (or Mac) to receive the audio stream?

• Scroll wheel causes browsers + Windows explorer to go back

  - by KaptajnKold

  I use Windows 7 on a VirtualBox VM on a Mac. Lately, when I'm using any browser (IE9, Chrome or FireFox or even Windows Explorer), use of the scroll wheel followed by any movement of the mouse cursor causes the browser to go back. Very annoying. This happens when I use the scroll wheel on a USB connected mouse (brand/model unknown, since I don't have it in front of me as I write this) or when I use two-finger scrolling on the trackpad when no mouse is connected. When I connect from my VM to a remote Windows box (Windows Server 2008), I experience the same problem. I have tried rebooting the VM to no avail. I am not sure when the problem started exactly. It may or may not have been after I connected the USB mouse for the first time, but trying to unplug it and then rebooting didn't help. I have tried to google for a solution, but all I've found are people who accidentally pressed the shift key while scrolling, which will cause the browser to go backward or forward in the browser history. This however is not the problem I'm having. To be clear, in my case the browser only goes back when I move the mouse after I've used the scroll wheel. I'm at my wits end :(

• What is the IPv6 equivalent to IPv4 RFC1918 addresses?

  - by Kumba

  Having a hard time wrapping my head around IPv6 here. A lot of the lingo seems targeted at enterprise-level IPv6 deployments, discussing link-local, site-local, global unicast, scopes, etc. Not a lot of solid information on really small networks, like home networks. I want to check my thinking and make sure I am getting the correct translations from IPv4-speak to IPv6-speak. The first question is, what's the equivalent of RFC1918 for IPv6? Initial searches suggested there was no equivalent. Then I stumbled upon Unique Local Addresses (RFC4193), and that states that all ULA's should be assigned the prefix fc00, followed by a 40-bit random number in the routing prefix. This random number is to "prevent collisions when two IPv6 networks are interconnected" -- again, another reference to an enterprise-level function. If I have a small local LAN at home, numbered using 192.168.4.0/24, what's my equivalent in IPv6's ULA scope? Assuming I will never, ever, tie that IPv6 address into the real internet (a router will NAT & firewall it), can I ignore the RFC to an extent and go with fc00::4:0/120? It also seems that any address in fc00::/7 are to be globally routable. Does this mean I'll need extra protections so my router would not automatically start advertising these private IPv6 addresses to the world? Second question, what's this link-local thing? Reading suggests a default-assigned address in the fe80::/10 range that has the last 64bits of the address comprised of the interface's MAC address. Seems to be required, too, but I'm annoyed by the constant discussion of it in relation to enterprise networks. Third question, what is scope id for? Seems to be yet another term tossed around in relation to enterprise networks, especially when interconnecting them, but almost no explanation on the smaller home network level. Can I see a scope ID AND CIDR notation used together? I.e., fc00::4:0/120%6, or are scope IDs only supposed to be applied to a single /128 IPv6 address?

• Joomla SMTP Configuration Issue

  - by msargenttrue

  I'm having an issue with the SMTP setup of my Joomla website when trying to send mass emails through the CB Mailing (Mass Email) extension. I receive this error: SMTP Error!

• Typing Japanese on Windows Vista with Dvorak

  - by Ken

  I'm using Windows Vista, and I type English with the Dvorak keyboard layout, and I want to be able to type Japanese text that way, too. I've figured out how to set it up to let me type Japanese here, but it uses QWERTY. What I've got so far is: click the "EN" in the taskbar, and select "JP" if the letter that appears in the taskbar is "A", hit alt-~ to change it to "?" type as if I was typing Romaji on a QWERTY keyboard, (e.g., left pinky home row, right ring finger top row), and hiragana appear (??) press spacebar to convert to kanji (e.g., ?), and return to accept That all works great, but it assumes I'm on QWERTY, which isn't very comfortable for me. I want everything the same, but to be able to type kana with Dvorak (e.g., left pinky home row, left ring finger home row - ??). I can do this on Mac OS, so it's not an unheard-of feature. But it was kind of an obscure setting to find, so I figure on Windows it's probably a really obscure setting. :-) But I haven't been able to find it yet. Thanks!

• Find out when a system went down?

  - by Clinton Blackmore

  I have a Mac OS X 10.5 server, with a RAID set in it, that went down due to a power outage on Thursday, and the machine is not happily booting right now*. It is possible to find out when the machine went down, while not booted off the internal drive? (I'm booted off an external drive, waiting for the RAID sets to initialize.) Normally, I'd run last. The man page doesn't indicate that I can run it against a different startup volume. It looks possible to parse /var/log/utmpx, but I don't think it'd be worthwhile to try to do that from scratch for this one-off problem. * I'm still trying to figure out why it isn't happy, and may ask a follow-up question. Right now I can see that UserNotificationCenter crashed repeatedly early Thursday morning, and that securityd, mdworker, and ARDAgent crash shortly after startup [I think -- I want to verify when the box went up and down]. The login window does not come up right (I think it is crashing or not able to cope with a dead securityd). The box is supposed to be set to go down when the UPS tells it power is out; at the moment, I'm wondering if it went down, and turned back on multiple times! I sure hope not.

• Installing and running a guest OS on KVM-qemu with only serial console access

  - by nixnotwin

  I am trying to installing a bsd distro with virt-installer. With a Linux distro I used this: virt-install -n debian -r 1024 --vcpus=1 --accelerate -v --disk /var/kvm/installation-disks/debian.img,size=6--nographics --network=bridge:br0,model=ne2k_pci,mac=52:54:00:66:68:09 -l http://ftp.de.debian.org/debian/dists/squeeze/main/installer-amd64/current/images/ -x console=ttyS0,115200 This loads the installer directly from the online mirror. With Fedora I used this mirror: http://www.nic.funet.fi/pub/mirrors/fedora.redhat.com/pub/fedora/linux/releases/16/Fedora/x86_64/os/ Are there such mirrors for freebsd or openbsd? The reason I want direct installable ftp/http mirrors is because I can access my physical server only via ssh, and it doesn't have a X server or a window manager to give me a VNC GUI. When I tried installing centos 6 with an online mirror I was able to finish the installation via serial console, but after I rebooted it, the serial console never worked for me. I tried everything possible---editing menu.lst, inttab and securtty files. Fedora 16 booted fine from serial console, but got stuck when it loaded anaconda installer. I tried editing freebsd iso installation media by adding serial console option to boot option. And installation was successful. But couldn't boot into it becuase it wasn't giving console acess. I couldn't edit any files as ufs partition cannot be loaded with write access on my Ubuntu server 10.04. Only debian squeeze worked well, it worked for me even without editing a single configuration file. I want to have CLI versions of fedora/centos and freebsd/openbsd. But, looks like there isn't any hope for me to have them, as I have to depend on a serial console to do everything.

• Disappearing Arial on 2 Macs

  - by drewk

  I noticed that Safari started rendering common web pages in a funny manner on two different Macs that I have. One is a Macbook Pro and the other a Mac Pro desktop. Yahoo and Google would appear all excessively bold or all italic and not at all look right or acceptable. The computers are all running OS X 10.6.3 "Snow Leopard" Turns out that "Arial.TTF" and "Arial Bold.ttf" got deleted somehow on these two computers. I restored Arial through Font Book and got my web mojo back. So questions: 1) Anyone seen "arial" strangely randomly disappear? The only thing in common is these are the only two computers out of eight on site that recently got Adobe CS 5 installed. Has anyone had CS 5 delete arial? 2) When I restored arial with font book, it goes into User fonts rather than the All fonts. Can I use Font Book to restore a font in /System/Library/Fonts or do I need to do that manually? 3) I located THIS article on the web regarding OS X fonts. Essentially, Snow Leopard did away with the older .dfont format and replaced with open True Type. There is a minimum font list, but Arial is not among them. Arial is installed by MS Office. 4) Why are web sites affected by Arial being missing anyway? If I look at the HTML source for Yahoo for example, "arial" is specified by name only in an ad. Yahoo itself does not specify a font name. In my Safari preferences, I have Times and Courier specified as the default font which is the default for Safari when installed. How does a missing Arial screw things up anyway? Thanks in advance.

• How to Load Balance 2 Internet Connections on a Windows 7 machine?

  - by Jimmy Chandra

  It's sort of related to this particular question, but that one is on Mac. I am looking for similar solution on Windows 7. I have 2 network connections: (Connection A) Wireless terminal connecting to ISP A (3G / EVDO internet provider) (Connection B) Broadband wired connection connecting to ISP B (Cable internet provider) Both has access to the internet. When I try connecting to a website and checking the networking tab on my Task Manager, I only see the network traffic being routed to only Connection A. Is there a way to make the computer to utilize both network (in a sense using all the bandwidth available from both the Cable ISP and the 3G / EVDO ISP) at the same time? If so, what do I need to do to set this up ... on Windows 7? Here is a bit more info on my network connections (ipconfig /all): PPP adapter Wireless Terminal: IPv4: aa.bb.ccc.ddd(preferred) Subnet mask: 255.255.255.255 Default Gateway: 0.0.0.0 DNS: aa.ee.f.ggg aa.ee.f.hhh Primary Wins: jjj.ii.k.l Secondary Wins: jjj.ii.k.m Ethernet adapter LAN: IPv4: 192.168.1.100 (connected to a router by wired that itself connect to a cable modem) subnet mask: 255.255.255.0 Default gateway: 192.168.1.1 (the wireless router) DHCP: 192.168.1.1 (the wireless router) DNS: xxx.yy.zz.ww rr.sss.t.uuu For my own privacy, I don't believe the actual number matters, the patterns are representative of the ip numbering scheme...

• How come my Intel 520 180GB SSD performs extremely poorly?

  - by Willem

  I recently installed a new Intel 520 series 180GB SSD in my brand new MacBook Pro. The system is as follows: Model: MacBook Pro 15-inch, Late 2011 (MacBookPro8,2) Processor: 2.4 GHz Intel Core i7 Memory: 16 GB 1333 MHz DDR3 Graphics: AMD Radeon HD 6770M 1024 MB Software: Mac OS X Lion 10.7.3 Main Drive Bay: Intel 520-series 180GB SATA-3 (6GB/s negotiated link) SSD (Firmware: 400i) [80GB free] Optical Bay: Toshiba 5400 RPM 750GB SATA-2 HDD Trim: Enabled (according to Trim Enabler App) And here are the speeds I'm getting: Read: 412 MB/s Write: 186 MB/s What have I done wrong? Results expected: Read/write both 500MB/s I have seen benchmarks with lesser SSD:s (SATA-2 even) outperform my write-speeds by far. Also, Intel 520 SSD:s are supposed to be the top class of SSD:s. Trim Enabler report: This looks a bit odd compared to screenshots from their site: These is the defined S.M.A.R.T attributes (taken from Intel): And here are my S.M.A.R.T attributes read using smartctl tool from smartmontools: They don't seem very compatible. I'm going to try and look for a S.M.A.R.T attributes reader tool for OS X which might support Intel 520 series.

• Visual Studio 2010 Beta 2, built-in font smoothing

  - by L. Shaydariv

  I've just installed Visual Studio 2010 Beta 2 onto my Windows XP to evaluate it and check whether it meets my preferences the way it did before. Okay, I've temporary defeated an urgent bug with a strange workaround (I could not open any file from the Solution Explorer), and it left bad memories to me. But however, it's okay. The first thing I've seen just opening the code editor was ClearType font rendering. Wow, so unexpectedly. I must note that I do not use standard Windows rendering techniques, but I still prefer GDI++, a font renderer developed by Japanese developers. (GDI++ allows to render the fonts in Mac/Win-Safari style over entire Windows.) Personally for me, GDI++ reaches the great font-rendering results allowing me to use the Dejavu Sans Mono font with really nice smoothing in Visual Studio 2008 (VS 2005 too, though VS 2005 crashes in this case). But GDI++ cannot affect Visual Studio 2010 Beta 2 text editor - it uses ClearType (right?), and it does not care about the system font smoothing settings. It could be an editor based on WPF, right? So as far as I can see, I can't use GDI++ anymore because it uses Windows GDI(+) but no WPF? So I've got several questions: Is it possible to disable VS 2010 b2 built-in ClearType or override it with another font smoother? Is it possible to install a Safari-like font renderer for Visual Studio 2010 [betas]? Thanks a lot.

• SSH freeze when UFW is enabled

  - by Cristian Vrabie

  I have a small Ubuntu 10.10 server and i recently noticed a weird behavior (not sure if it was happening before). If I have ufw enabled (with default deny all in, allow all out, allow all http, allow all on a random port i use for ssh) when i perform some actions in a ssh sesion, the ssh console completely freezes. The server continues to work and if i close the console i can start another ssh session. This happens no matter from where I log in (tried from another ubuntu and a mac). The actions are fairly reproducible, for example vim some config files (though vim-ing other files works), cat some other file, etc. The freeze never happens if ufw is disabled. Any idea what's going on? Thanks! Cristian Addition: if you're wondering, yes, I have TcpKeepAlive on yes and I doubt is related (it would happen with ufw disabled too) As requested: my ufw conf below. Also, i don't know if it has something to do but the server has 2 ips. On one is configured the ssh domain, and on one to serve hhtp (via apache2) Status: active Logging: on (low) Default: deny (incoming), allow (outgoing) New profiles: skip To Action From -- ------ ---- 19922/tcp ALLOW IN Anywhere 9418/tcp ALLOW IN Anywhere 80/tcp ALLOW IN Anywhere 443/tcp ALLOW IN Anywhere

• Windows and file system abstraction - how much does it matter where something comes from?

  - by deceze

  I have come across the following phenomenon and would like to know how leaky Windows' file system abstraction is or if there's something else involved. I partitioned the hard disk of my MacBook Pro and installed Windows 7 (64 bit). The Bootcamp driver package includes file system drivers (right term?) that enable Windows to access the Mac OS HFS+ partition. AFAIK it's a read-only access, but it works. Now, I have some disk images of stuff I usually install, so I grabbed a copy of Daemon Tools to mount them. When I mount an image saved on the HFS+ partition, about two out of three installers on these disks (usually InstallShield) crash with all sorts of weird errors. Most are just gibberish that lead to all sorts of non-solutions on Google, one was "This application is not the right type for your computer, check if you need 32 or 64 bit versions." When moving the image files to another Windows 7 computer on the network and mounting them from the network share, they work fine. My question now is, why do applications behave differently depending on whether the read-only image file, which should be abstracted away through the read-only virtual Daemon Tools drive, is located on a read-only HFS+ partition or on a Windows network share? And I'll just roll this into the question as well since I was wondering: Does the file system of a network share matter? Does the client system need to understand the file system of the share host or is that abstracted away in SMB?

• Connecting jconsole using SOCKS to Amazon EC2

  - by freshfunk

  I'm trying to use jconsole to view stats on an EC2 instance by using a socks proxy created by SSH. I've tried the various scripts mentioned in the links below but to no avail: http://simplygenius.com/2010/08/jconsole-via-socks-ssh-tunnel.html http://gabrielcain.com/blog/2010/11/02/using-ssh-proxying-to-connect-jconsole-to-remote-cassandra-instances/ I'm running ssh -f -ND 8123 myuser@mymachine and verified that at least Firefox goes through it as a proxy. I then run jconsole -J-DsocksProxyHost=localhost -J-DsocksProxyPort=8123 service:jmx:rmi:///jndi/rmi://ec2-XX-XX-XXX-XXX.compute-1.amazonaws.com:8080/jmxrmi I run netstat -n on my EC2 instance and I see a connection created by my machine. However, the connection eventually disappears and I get a 'channel 2: open failed: connect failed: Operation timed out' from my ssh tunnel. I've opened the jmx port through the security group and I've checked the port on the EC2 instance to make sure it's open (by telnet-ing to it). I'm not sure where to look next. Are there some properties in sshd_config or ssh_config I need to enable for tunneling? Or anything in Mac OS X? I feel like a serious noob but sys administration is really not my strong point. I've spent several hours and can't get this to work.

  - by KPthunder

  I have a directory listing as follows (given by ls -la): total 8 drwxr-xr-x 6 <user> <group> 204 Oct 18 12:13 . drwxr-xr-x 7 <user> <group> 238 Oct 18 11:29 .. drwxr-xr-x 14 <user> <group> 476 Oct 18 12:31 .git -rw-r--r-- 1 <user> <group> 601 Oct 18 12:03 index.html drwxr-xr-x 2 <user> <group> 68 Oct 18 12:13 test drwxr-xr-x 2 <user> <group> 68 Oct 18 12:13 test2 Running ack . -f prints out the files in the directory: index.html How can I get ack to print out the directories in the directory? I want to ignore the .git directory (which I understand is default behavior for ack). On that note, how can I ignore certain directories? I am using ack 1.9.6 on Mac OSX 10.8.2.

• Kickstart: Serve dynamic kickstart images via a CGI or PHP script?

  - by Stefan Lasiewski

  I'd like to kickstart a couple dozen RHEL6/SL6 servers. However, some of these servers are different and I don't want to create a new ks.cfg file for each class of server. Are there any products which can generate a Kickstart file dynamically on the fly, from a template? For example, if I append a line like this to the KERNEL: APPEND ks=http://192.168.1.100/cgi-bin/ks.cgi Then the script ks.cgi can determine what host this is (Via the MAC address), and print out Kickstart options which are appropriate for that host. I could optionally override some options by passing parameters to the script, like this: APPEND ks=http://192.168.1.100/cgi-bin/ks.cgi?NODETYPE=production&IP=192.168.2.80 After we kickstart the server, we activate Cfengine/Puppet on this system and manage the system using our favorite Configuration Management product. We're experimenting with xCAT but it is proving too cumbersome. I've looked into Cobbler, but I'm not sure it does this. Update: A roll-your-own solution is discussed in the O'Reilly book: Managing RPM-Based Systems with Kickstart and Yum, Chapter 3. Customizing Your Kickstart Install Dynamic ks.cfg, which echos some of the comments in this thread: To implement such a tool is beyond the scope of this Short Cut, but I can walk through the high-level design. Any such solution would mix a data store (the things that change) with a templating solution (the things that don’t change). The data store would hold the per-machine data, such as the IP address and hostname. You would also need a unique identifier, perhaps the hostname, such that you could pick up a given machine’s data. The data store could be a flat file, XML data, or a relational database such as PostgreSQL or MySQL. In turn, to invoke the system, you pass a machine’s unique identifier as a URL parameter. For example: boot: linux ks=http://your.kickstart.server/gen_config?host-server25 In this example, the CGI (or servlet, or whatever) generates a ks.cfg for the machine server25. But where, oh where, is the code for ks.cgi?

• What steps should I take to debug this non-starting hvm virtual machine?

  - by Ophidian

  I have a dom0 machine running CentOS 5.4 with all the latest updates using Xen as my hypervisor. I am using Xen in part because this machine was set up prior to KVM being included in RHEL, and in part because KVM's network bridging configuration is not nearly as simple as Xen's. The dom0 machine is headless and I do all of my VM management via virsh from the command line. I have two hvm domU's: A web server running CentOS 5.4 A mail server running Gentoo Both VM's are backed by LV's on the dom0 but do not use LVM in the domU. Both have virtually identical libvirt configurations (differing by expected things like name, UUID, NIC MAC, VNC port, etc). The web server domU (WSdomU hereafter) does not start since applying the most recent kernel update (kernel-xen-2.6.18-164.15.1.el5.x86_64 and kernel-2.6.18-164.15.1.el5.x86_64 for the dom0 and WSdomU respectively). By 'not start' I mean it appears to be running but it does not use an CPU cycles, does not bring up a graphical console, and does not respond on the network. The WSdomU is listed as no state rather than the normal running or blocked in xentop. The mail server domU starts fine and functions normally. Here are the steps I have taken so far that did not solve the problem: Reboot the dom0 to see if things come up on their own Check xen dmesg on dom0 Check xend logs (a cursory viewing did not show anything blatant; specific suggestions of things to look for would be appreciated) Attempted to connect to the WSdomU's graphical (VNC) console from the dom0 Shutdown the mail server domU and attempt to start the WSdomU Check the SELinux labels on backing LV's (they're the same) Set SELinux to permissive and attempt to start the WSdomU Use virsh edit to try tweaking the WSdomU config virsh undefine, reboot, virsh define the WSdomU config dd the WSdomU LV to an .img file, copy it to my Fedora desktop and run it under KVM (works fine) What steps should I take next to debug this? I will edit in any additional configuration's requested in the comments.

• mod_rpaf with apache error_log

  - by Camden S.

  I'm using mod-rpaf with Apache 2.4 and it's working properly (showing the real client IP's) in my Apache access_log... but not in my error_log. My error log just shows the client IP address of the proxy server (my load balancer in this case) Here's an example of what I see in my error_log where 123.123.123.123 is the IP of my load balancer/proxy. == /usr/local/apache2/logs/error_log <== [Tue Jun 05 20:24:31.027525 2012] [access_compat:error] [pid 9145:tid 140485731845888] [client 123.123.123.123:20396] AH01797: client denied by server configuration: /wwwroot/private/secret.pdf The exact same request produces the following in my access_log where 456.456.456.456 is a real client IP (not the IP of the load balancer). 456.456.456.456 - - [05/Jun/2012:20:24:31 +0000] "GET /wwwroot/private/secret.pdf HTTP/1.1" 403 228 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:12.0) Gecko/20100101 Firefox/12.0" Here's my httpd.conf entry: # RPAF LoadModule rpaf_module modules/mod_rpaf-2.0.so RPAFenable On RPAFproxy_ips 127.0.0.1 123.123.123.123 RPAFsethostname On RPAFheader X-Forwarded-For What do I need to do to get the real IP addresses showing in my Apache error_log?

• Samba4/Ubuntu Shares Incorrectly Available to All Users

  - by Dan

  I've got my Ubuntu server working with Samba4 and got it set up as the Primary domain controller on my network with AD and all that goodness. However, I'm trying to get my Samba configuration to work with the users and groups I've defined with the Active Directory tools from Windows. For instance, I've got a share X which I want users A and B (as part of the 'management' group, known as LLGrpManager in my setup) to see, but no body else. However, after making changes to the configuration, restarting Samba, I test by connecting to the share with my Mac over Samba as user 'C' which isn't part of the management group, and I can, incorrectly, see the X share. I've tried alsorts of combinations of specifying the group with no luck at all. I've got a feeling that my global config might be too lenient or something to do with file permissions but being a bit green, I'm without clue. My /etc/samba/smb.conf # Global parameters [global] server role = domain controller server string = Office Server workgroup = LLDOMAIN realm = lldomain.local netbios name = DUMBO passdb backend = samba4 logon path = \\%L\profiles\%U logon drive = L: log file = /var/log/samba/%m.log max log size = 50 security = ads domain logons = yes domain master = auto usershare allow guests = no valid users = %S [netlogon] path = /var/lib/samba/sysvol/lldomain.local/scripts read only = no guest ok = no [sysvol] path = /var/lib/samba/sysvol read only = No guest ok = no valid users = @LLDOMAIN\LLGrpManager [ShareX] path = /data comment = Entire Data Volume guest ok = no comment = Entire Data Volume guest ok = no valid users = @LLDOMAIN\LLGrpManager admin users = @LLDOMAIN\LLGrpManager browsable = no inherit acls = yes inherit permissions = yes ... My /etc/nsswitch.conf I've also instructed the system to use the nss winbind library when searching for users or groups by adding the stanza passwd and group in /etc/nsswitch.conf: passwd: compat winbind group: compat winbind shadow: compat Permissions on the folder in question drwxrwxrwt 8 root root 4.0K Oct 28 19:11 data

• Is ffmpeg incorrectly interpreting .aif files?

  - by marue

  Being on an Ubuntu 10.04 server i installed the ffmpeg packages with apt. ffmpeg is working afterwards, and doing as it should. Almost. For testing purposes i uploaded a few audiofiles. One of them, an aif file, is not being correctly interpreted. While on my workhorse (Mac SnowLeopard) ffmpeg tells the format as Stream #0.0: Audio: pcm_s24be, 44100 Hz, 2 channels, s32, 2116 kb/s my Ubuntu server says it is: Stream #0.0: Audio: pcm_s24be, 44100 Hz, stereo, s16, 2116 kb/s which is the wrong bitdepth. Ubuntu then fails to convert the file with the error message [pcm_s24be @ 0xcd4b580]invalid PCM packet Error while decoding stream #0.0 which certainly is not true. The file is perfectly valid. Are there any know issues for ffmpeg interpreting the aif format? How can i find out which version of the aif-codec ffmpeg is using? Any ideas how to approach this issue? ffprobe output: FFprobe version SVN-r20090707, Copyright (c) 2007-2009 Stefano Sabatini libavutil 49.15. 0 / 49.15. 0 libavcodec 52.20. 0 / 52.20. 1 libavformat 52.31. 0 / 52.31. 0 built on Jan 20 2010 00:13:01, gcc: 4.4.3 20100116 (prerelease) Input #0, aiff, from 'testfile.aif': Duration: 00:00:04.00, start: 0.000000, bitrate: 2117 kb/s Stream #0.0: Audio: pcm_s24be, 44100 Hz, stereo, s16, 2116 kb/s update 2: Forcing the conversion with -sample_fmt s32 doesn't change anything. Strange thing is: Even without using -sample_fmt s32 i just realized that the conversion is working and creates valid audiofiles. There just is the error message from above.

• "Safe" personal router use on apartment-wide network

  - by noisetank

  I recently moved into an apartment with internet included in my rent. This was a boon at first, but now I'm feeling limited. To get devices connected (wired or wireless), I have to whitelist the MAC addresses on mycampusnet.com. This is annoying (considering I'm well over the 10 device limit including my roommate's stuff), but what's really driving me mad is that I don't seem to have any semblance of a "local" network. I've relied heavily on static IPs and port forwarding in the past (accessing NAS and remote desktop) and (as far as I can understand), that functionality is nonexistent without my router set up. Also, as my wired and wireless devices don't always seem to make it onto the same subnet, I'm unable to use any of my iDevices with my Apple TV (I can, however, mirror to no less than four strangers' Apple TVs at any moment, which is a whole other level of discomforting). I've talked to the head of the apartment complex and she told me that they personally don't have any issue with my using a router, but the provider (CampusConnect) does not currently allow it. Apparently, enough people have put in complaints/requests about the restriction (the apartments are for graduate students and University staff, many of which need to set up things like VPNs for work reasons) to open up some sort of ticket to get the functionality in place, but all the calls I've made to get status updates have been a waste of time. My question is: If I plugged my router into the apartment network, what would happen? I've been told already that personal routers would "interfere with the wireless" and that they would shut my port down if I used one, but is that a legitimate thing or just something made up that sounds real to keep the average Joe from pushing it further? I'm guessing there's some way of configuring my router to keep it from disrupting the rest of the network, but it's not something they want to tell me for obvious reasons. Am I right? And if so, what are the chances that they'd notice the difference in traffic or whatever and shut off my port?
