  • Ubuntu 12.04 - Pound Reverse Proxy and Adobe Flex/Flash Auth

    - by James
    First time posting, I have a completely fresh install of ubuntu 12.04 Client as a reverse proxy gateway to our internal network. Our setup is we have one external ip but three domains we would like to point to various webservers on our internal network. It's not so much a load balancing issue or cacheing etc. Merely routing some Client browsers to a port 80 webpage (to adhere to some stricter corporate policies regarding placing port numbers after domain names). I have gone with pound and everything seems to be working fine. Static pages load etc. Everything is good with the exception of a Flash/Flex based WebClient for a Digital Asset Management program. The actual static page loads fine, it is just at the moment of entering credentials, be they correct or incorrect, and hitting login, there is no response whatsoever. Either a rejection or confirmation etc. So the request back to the internal server can't be getting through. I have googled extensively and there might be a solution in a crossdomain.xml file? Documentation isn't very clear. And we are not the authors of the DAM app, and have no control over the code on the Flash/Flex side. Questions: Is there a particular config file/solution for pound that allows Flash/Flex auth information to be forwarded? Is there another reverse proxy program (nginx?)that allows this type of config? Am I looking at this the entire wrong way, should Flash/Flex fundamentally not be allowed to have this access?

  • Ubuntu in VirtualBox File Modified Time in Future and PHP slow file operations

    - by user1750
    For some reason, some of my files have a last modified date in the future. In addition to this, file operations in PHP are SUPER slow. For example, rebuilding the Symfony2 cache can take over 40 seconds (its takes 1-2 on my MacBook Pro). Notice the time for ListingsCRUDController.php. It just says "2012". In order see the date more clearly I ran ls --time-style="full-iso" -l For some reason it shows that this file's last modified date is ~5 hours into the future. System time: To make things more confusing, the system will intermittently speed up. Suddenly, my app will start serving requests in 1-2 seconds (down from 40 seconds) for no apparent reason. I mean I don't do anything to my code/system config - it just changes. Also, during a slow PHP request, the php5-fpm process (nginx) uses 100% of the CPU for the duration of the request. This is the second VM this has happened on and I need to know why its doing this. It has become unusable. Information About My Setup VirtualBox 4.2.0 Host: Macbook Pro Guest: Ubuntu Server 12.04 Package dkms is installed Timezones match for Ubuntu and PHP. Things I've Tried Both Apache and Nginx. APC enabled and disabled. Xdebug enabled and disabled. 1 processor up to 4 processors. 1gb memory up to 4gb memory. I've installed Ubuntu using the regular kernel and the VM kernel.

  • How to find cause of main file system going to read only mode

    - by user606521
    Ubuntu 12.04 File system goes to readonly mode frequently. First of all I have read this question file system is going into read only mode frequently already. But I have to know if it's not caused by something else than dying hard drive. This is server provided by my client and I am just runing there some node.js workers + one node.js server and I am using mongodb. From time to time (every 20-50h) system suddenly makes filesystem read only, mongodb process fails (due read-only fs) and my node workers/server (which are started by forever) are just killed. Here is the log from dmesg - I can see there some errors and messages that FS is going to read-only, and there is also some JOURNAL error but I would like to find cause of those errors.. http://speedy.sh/Ux2VV/dmesg.log.txt edit smartctl -t long /dev/sda smartctl 5.41 2011-06-09 r3365 [x86_64-linux-3.5.0-23-generic] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net SMART support is: Unavailable - device lacks SMART capability.

  • Migrating Windows XP BOOT.INI Settings to Windows 7 Boot-loader

    - by Synetech inc.
    Hi, Two months ago my motherboard died, so I bought a used computer that came with Windows 7. I have since installed my old hard-drive, which had Windows XP on it, in this system. What I am trying to do now is to figure out a way to migrate the settings from XP's BOOT.INI into 7's boot-loader. Below is the BOOT.INI I used in XP (I have reduced the strings and updated the disks to point to the new location of the old HD. Oh and I am not clear on the drive letters. In XP, I could boot the recovery console or MS-DOS from a file in C:\ that contains the boot-sector. I am not sure what drive letter it would be called now—I had to manually change all the drive letters of the old partitions in Windows 7 because it auto-assigned them all wrong/differently). [boot loader] timeout=10 default=multi(0)disk(0)rdisk(1)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="XP" /fastdetect multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="XP (Safe)" /safeboot:network /sos /bootlog /noguiboot C:\CMDCONS\BOOTSECT.DAT="Recovery Console" /cmdcons C:\BOOTSECT.DOS="MS-DOS 7.10" /win95 I have looked around, and have only been able to find some bcdedit commands to add XP to the boot-loader, but none that include information on setting safe-mode for it (or changing any of the XP load options for that matter). Not surprisingly I suppose, I have not found anything on adding the XP recovery console or DOS to the Windows 7 boot-loader. (Yes, I tried EasyBCD, but that did not help; it had no options for XP, and the best I managed was to get a choice of booting 7 or normal-mode XP—choosing XP didn't even give the old XP boot menu.) Can anyone please tell me how to export the entries in XP's boot.ini to 7's boot-loader so that on boot, I can choose to load the following: Windows 7 Windows 7 (Safe-mode) (Windows 7 (The Win7 counterpart of the Recovery Console)) Windows XP Windows XP (Safe-mode) Windows XP (Recovery Console) MS-DOS 7.10

  • Can't connect to Sql Server 2008 named instance

    - by eidylon
    I just installed Sql 2008 Express on a new server running Windows Server 2008. I know Sql is working properly, because I can connect to the db fine locally, on the server. I cannot connect to it from a client machine though, neither by IP address nor by machine name (iporname\instance). I know I have the correct IP address, because I am RDCing into the server to perform all this configuration and setup, and if I ping the server name, it is resolving to the correct IP address as well. On the server, I have set up an inbound firewall exception allowing all traffic on any port on any protocol to sqlservr.exe. In SSMS, in server > Properties > Connections Allow remote connections to this server is enabled. In Sql Server Configuration Manager, TCP/IP is enabled in both the Protocols for <instance> and the Client Protocols sections. I looked in the Windows logs, but don't see anything about connections being denied or dropped. As far as I can see, I have everything set right, but cannot connect from a client machine. The client CAN connect to other Sql 2008 Express servers okay, so I know the client configuration is correct. Any ideas where else I can look for info of what/where/how this connection is dropping, greatly apprecaited! The error being returned by the client is: **TITLE: Connect to Server** Cannot connect to [MY.IP.ADD.RSS]\[MYINSTNAME]. ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)

  • Why is mkfs overwriting the LUKS encryption header on LVM on RAID partitions on Ubuntu 12.04?

    - by Starchy
    I'm trying to setup a couple of LUKS-encrypted partitions to be mounted after boot-time on a new Ubuntu server which was installed with LVM on top of software RAID. After running cryptsetup luksFormat, the LUKS header is clearly visible on the volume. After running any flavor of mkfs, the header is overwritten (which does not happen on other systems that were setup without LVM), and cryptsetup will no longer recognize the device as a LUKS device. # cryptsetup -y --cipher aes-cbc-essiv:sha256 --key-size 256 luksFormat /dev/dm-1 WARNING! ======== This will overwrite data on /dev/dm-1 irrevocably.

  • Choosing the right TV tuner - USB or PCI TV tuners, hardware/software, DVB? Hybrid/combo/analog?

    - by Nucleon
    Greetings, I'll start with some background information so you know what I'm trying to accomplish and then get to my question. I work at a Television station in the US and we are working on setting up an online DVR/Podcast system for all of our newscasts. So basically we would be recording every newscast in HD, encoding it to flv/h.264 for viewing in a browser on flash compatible and iphone/ipad devices, eventually migrating to WebM when it's browser compliant. This task is theoretically pretty simple as it all it involves is a TV tuner device and a program like VLC, MythTV or whatever to schedule and dump it to a file, encode it with VLC/FFMPEG and push it to the streaming server. Now to the hardware, in order to accomplish that task, should I use an internal PCI tuner or a USB 2.0 tuner? Is there a difference? The bus speeds of both are not too far apart, and is the bus speed really relevant in this case? Does it matter if the device has a hardware encoder or a software encoder? On many sites the USB was recommended for ease of set up and use, but would it overly task a processor, or is that not a concern as long as it's a decent PC (at least duo core, 6gb ram). What's the difference between the stick USB and the Box USBs? To my understanding analog is basically gone in the US, so we would want a hybrid or combo tuner correct? How do those differ from DVB? Are there any other features or concepts which I am missing which may influence the recommended product. It would be ideal if the device which could work in both Linux and a Windows environment, to my knowledge most Hauppauge are? Example 1: PCI Hauppage http://www.newegg.com/Product/Product.aspx?Item=N82E16815116033 Example 2: USB 2.0 Box http://www.newegg.com/Product/Product.aspx?Item=N82E16815116029 Example 3: USB 2.0 Stick http://www.newegg.com/Product/Product.aspx?Item=N82E16815116031 Any guidance from the Superusers would be much appreciated!

  • Windows 2008 R2 remote desktop - Double Login

    - by Zulgrib
    After an Active Directory fail RDP connection started to ask for credentials twice (once on local RDP program, second time on remote's logon screen) I already looked at Windows 2008 R2 RDS - Double Login Solution provided there doesn't work for me. The server is alone, without AD/DNS services, RDP service isn't installed I tried every security settings on RDP-Tcp (RDP, Negotiate, SLL) Logon option is set to "Use credentials from the client" Both windows client and server use RDP 7.1 fPromptForPassword regitries are set to 0 Local Computer Policy\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Security\Always prompt for password upon connection is set to "Disabled" Why i am sure the problem comes from the server and not the client ? This problem affected a 3rd RDP program on Android too (it was directly showing "preparing desktop previously, on both MS RDP and the 3rd program) No bakcup are available (Else the Active Directory wouldn't be a fail, but just a lose of time) I am wondering if a rule linked to RDP got changed after the AD install+unistall, but i'm unable to find where. While this is not a critic problem, this is very annoying. I don't know if more information are needed, if it's the case and if you are patient enough, please tell me what is missing and i'll edit this post to add the missing informations.

  • DNS setup problems with Windows Azure VPS

    - by jbigelow
    What is the proper to setup the A record (or CNAME) for a Windows Azure VPS? I can't connect to my website after setting up IIS and believe I don't have the correct DNS setup. I created a small VPS instance with the default Windows Server 2012 configuration. I RDP'd in and added the Webserver role. In my DNSMadeEasy control panel I added an A record with my Public Virtual IP Address. In IIS I went to the default website and added bindings for the hostname of my website, so I should be able to type mywebsite.com and see the IIS 8 splash screen, but instead my browser cannot connect. I attempted to navigate to the site by typing in my Virtual IP address into the browser and still cannot connect. I RDP'd back into the machine and turned off Windows Firewall. No change, still cannot navigate to my website. From within IIS I double checked my binding. If I click "browse *:80" I can bring up my website in IE with the http:// localhost address. If I click "browse mywebsite on *.80" IE says "This page cannot be displayed.", from within the RDP session I can view the site if I navigate to http:// 127.0.0.1 but not if I navigate to my Virtual IP, nor can I view the page if I try navigating to http:// mywebservername.cloudapp.net I'm thinking I must be fundamentally not understanding how do DNS setup with Azure VPS but my initial Google searches aren't turning up any helpful information. (spaces added after the http:// so serverfault doesn't try and render them as valid urls.)

  • Max. Bandwidth Cannot be Reached

    - by Poyraz Sagtekin
    I have a question regarding the bandwidth usage. I don't think it's a very technical question but I really want to know the reason behind the problem. I'm having my education in one of my university's campuses. There is a 200mbps bandwidth availability for approx. 2100 students. Our main campus has 25,000 students and 2gbps bandwidth and there is no problem with the internet connection speed in main campus. However, in my campus, we are having difficulties with the internet connection speed. I went to IT department of my university and they've showed me some graphics about the bandwidth usage. The usage of the bandwidth has never reached 200mbps and it generally is around 130-140mbps. According to this information, maximum bandwidth is never made by the users but the browsing speed is not very convincing. What can be the problem? Maybe this is a silly question but I really want to know the reason. They told me that they've reached 180mbps before.

  • Mplayer no sound when playing some movies

    - by Ivan Peevski
    Ok, that's a bit of a strange problem, that somehow crept into my system. It used to work fine. Here is the problem as far as I can identify it. When I try to play certain video files with mplayer, there is no sound. As far as I can tell, it is only an issue with ac3 and dts sound tracks (using the ffmpeg decoder). Mplayer says: ========================================================================== Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders AUDIO: 48000 Hz, 6 ch, s16le, 1536.0 kbit/33.33% (ratio: 192000->576000) Selected audio codec: [ffdca] afm: ffmpeg (FFmpeg DTS) ========================================================================== [AO_ALSA] Playback open error: Device or resource busy Failed to initialize audio driver 'alsa' Could not open/initialize audio device -> no sound. Audio: no sound (similar with ac3 sound, but using the ffac3 audio codec). Trying different audio output (-ao oss/pcm/sdl) doesn't fix the problem. The strange thing is that if I play these files directly with ffplay, they work fine. mplayer sound with mp3/ogg is fine My alsa configuration is standard (no /etc/asound.conf or ~/.asound*) OS: Linux Gentoo Mplayer: 1.0_rc4_p20100213 (SVN-r30554-4.3.4) FFMpeg: 0.5_p20601-r1 (SVN-r20601) Any other information I can provide?

  • Eclipse grinds to a halt when building workspace

    - by Chris Thompson
    Hi all, This is a bit of a vague question because, frankly, I don't even know where to begin diagnosing the issue. My eclipse (Galileo) installation grinds to a complete halt when it's building the workspace -- to the point where I can't even type. I know the Android SDK I have installed is a major culprit because I can watch the memory usage go through the roof (through the built-in heap monitor) when the Android SDK content loader starts up. Every time I save a file though, the program just stops. The message at the bottom of the screen says Building workspace (74%) and sits there for about 30 or so seconds before completing and returning the performance to normal. I have a few other plugins installed (Maven, SVN, etc) but I'm assuming the main issue is Android. Has anybody had similar issues or any luck correcting this sort of problem? If there's anymore information you think would be helpful, just let me know...I didn't want to do a core dump on this question... I'm running it on Windows 7 64-bit for what it's worth. Thanks! Chris

  • Recommended programming language for linux server management and web ui integration

    - by Brendan Martens
    I am interested in making an in house web ui to ease some of the management tasks I face with administrating many servers; think Canonical's Landscape. This means doing things like, applying package updates simultaneously across servers, perhaps installing a custom .deb (I use ubuntu/debian.) Reviewing server logs, executing custom scripts, viewing status information for all my servers. I hope to be able to reuse existing command line tools instead of rewriting the exact same operations in a different language myself. I really want to develop something that allows me to continue managing on the ssh level but offers the power of a web interface for easily applying the same infrastructure wide changes. They should not be mutually exclusive. What are some recommended programming languages to use for doing this kind of development and tying it into a web ui? Why do you recommend the language(s) you do? I am not an experienced programmer, but view this as an opportunity to scratch some of my own itches as well as become a better programmer. I do not care specifically if one language is harder than another, but am more interested in picking the best tools for the job from the beginning. Feel free to recommend any existing projects that already integrate management of many systems into a single cohesive web ui, except Landscape (not free,) Ebox (ebox control center not free) and webmin (I don't like it, feels clunky and does not integrate well with the "debian way" of maintaining a server, imo. Also, only manages one system.) Thanks for any ideas! Update: I am not looking to reinvent the wheel of systems management, I just want to "glue" many preexisting and excellent tools together where possible and appropriate; this is why I wonder about what languages can interact well with pre-existing command line tools, while making them manageable with a web ui.

  • Lock down Wiki access to password only but remain open to a subnet via .htaccess

    - by Treffynnon
    Basically we have a Wiki that has some sensitive information stored in it - not the best I know but my predecessor set it up. I want to be able to request password access from any one who is not on the local network subnet. Those on the local subnet should be able to proceed without entering a password. The following .htaccess does not seem to work any more as it is letting non-local access without requiring the password: AuthName "Our Wiki" AuthType Basic AuthUserFile /path/to/passwd/file AuthGroupFile /dev/null Require valid-user Allow from 192.168 Satisfy Any order deny,allow And I cannot work out why. The WikkaWiki it is supposed to be protecting was recently upgraded, which clobbered the .htaccess file so I restored the above from memory/googling. Maybe I am missing an important directive? The full .htaccess is as follows: AuthName "Our Wiki" AuthType Basic AuthUserFile /path/to/passwd/file AuthGroupFile /dev/null Require valid-user Allow from 192.168 Satisfy Any SetEnvIfNoCase Referer ".*($LIST_OF_ADULT_WORDS).*" BadReferrer order deny,allow deny from env=BadReferrer <IfModule mod_rewrite.c> # turn on rewrite engine RewriteEngine on RewriteBase / # if request is a directory, make sure it ends with a slash RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^(.*/[^/]+)$ $1/ # if not rewritten before, AND requested file is wikka.php # turn request into a query for a default (unspecified) page RewriteCond %{QUERY_STRING} !wakka= RewriteCond %{REQUEST_FILENAME} wikka.php RewriteRule ^(.*)$ wikka.php?wakka= [QSA,L] # if not rewritten before, AND requested file is a page name # turn request into a query for that page name for wikka.php RewriteCond %{QUERY_STRING} !wakka= RewriteRule ^(.*)$ wikka.php?wakka=$1 [QSA,L] </IfModule>

  • Is one server on a vlan unnecessary?

    - by moomoochoo
    DETAILS I've been researching web hosting solutions in Japan. Based on this question one of the services available seems to be a VLAN. I've read about the advantages of such a system for a large organization, but there doesn't seem to be much information regarding smaller setups. I take that to mean that for one server it is likely to be unnecessary? My concern is that I don't know how many other servers are on the WAN, so regardless of how many servers I use a VLAN might still be a good idea. SERVER INFO One dedicated server would be used. It would not be virtualized. My Research so far Based on comments here, a VLAN would be useful for mitigating these problems. A user on another server could, either mistakenly or maliciously, assign one of your IP addresses to their server, resulting in a "duplicate IP" situation that would cause connectivity issues. A user on another server could poison the arp cache and potentially redirect traffic to snoop on communication intended to/from your server. (later in the discussion this point was said to be unrealistic.) QUESTION Is it worthwhile getting a vlan for one dedicated server? Will it be easier/the same/ harder to manage?

  • Powershell: Execute exe on remote server and capture output

    - by user364825
    I am trying to script the execution of an installer on remote web servers. The installer in question is also a Windows Service that hosts NServiceBus. If RDP'd into the server, the application is installed by the following command: &"$theInstaller" /install /serviceName:TheServiceName The installer prints output about its progress registering the service and connecting to the database to stdout, among other things. This works fine from an RDP session, but when I execute it remotely via PS, I get a you-can't-do-this-over-the-network message if I execute it directly or via Invoke-Command -computername $theRemoteServer: System.IO.FileLoadException: Could not load file or assembly 'file://\\theRemoteServer\c$ \thePath\AutoMapper.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) --- System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information. (Note: I added an additional "\" to the path in the first line in order to get it to show up correctly in the preview on this site.) This, and other DLLs, are loaded by the service, and the service's execution context cannot, apparently, be remotified. I have also tried using Invoke-WmiMethod, which does something, but it's not clear what, and the output from the installer is lost: Invoke-WMIMethod win32_process create '"$theInstaller" /install /serviceName:TheServiceName' -ComputerName $server (with and without cmd.exe /k before the intaller reference): __GENUS : 2 __CLASS : __PARAMETERS __SUPERCLASS : __DYNASTY : __PARAMETERS __RELPATH : __PROPERTY_COUNT : 2 __DERIVATION : {} __SERVER : __NAMESPACE : __PATH : ProcessId : ReturnValue : 9 How does one remotely execute such an EXE and capture the output? Thanks!

  • Mac 10.5 Python libsvm 64 bit vs 32 bit

    - by shadowsoul
    I have a Mac 10.5 when I type "python" in terminal, it says Enthought Python Distribution -- www.enthought.com Version: 7.3-2 (64-bit) Python 2.7.3 |EPD 7.3-2 (64-bit)| (default, Apr 12 2012, 11:14:05) [GCC 4.0.1 (Apple Inc. build 5493)] on darwin Type "credits", "demo" or "enthought" for more information. then I go to my libsvm/python folder and type "make" which results in make -C .. lib if [ "Darwin" = "Darwin" ]; then \ SHARED_LIB_FLAG="-dynamiclib -W1,-install_name,libsvm.so.2"; \ else \ SHARED_LIB_FLAG="-shared -W1,-soname,libsvm.so.2"; \ fi; \ g++ ${SHARED_LIB_FLAG} svm.o -o libsvm.so.2 when I try to do "from svmutil import *" I get the error: OSError: dlopen(.../libsvm-3.12/python/../libsvm.so.2, 6): no suitable image found. Did find: .../libsvm-3.12/python/../libsvm.so.2: mach-o, but wrong architecture when I do "lipo -info libsvm.so.2", I get: Non-fat file: libsvm.so.2 is architecture: i386 So it looks like I'm running 64-bit python but libsvm ends up as a 32-bit program. Any way I can get it to compile as a 64-bit program?

  • IIS8 behind a VPN + Windows Server 2012 - how to properly bind IP+Port

    - by ryugen
    This is my first question so I hope I'm going to give you enough information. I'm running Windows Server 2012 within the Hyper-V environment of my Windows 8 machine. Within Windows Server 2012 I'm running a VPN tool based on openVPN to hide my real IP. When I run IIS8 with the VPN disconnected it works flawlessly through the Internet (port 80 forwarded correctly). But as soon as I connect to the VPN I can't reach my site through the domain anymore. Now I tried basically everything I know which is why I'm asking you guys. I tried binding IIS8 to the IP of my virtual ethernet card. I tried changing the priority of the NIC through the "Network and sharing center" via the advanced tab. I used ipconfig /flushdns in case there was something wrong in the DNS handling. Hell, I even turned off the Windows firewall. I also used a port scanner to verify the problem. The webserver is reachable on port 80 with VPN disconnected and immediately gets unreachable on connect. Theoretically both IPs (my regular one AND the VPN) should be reachable or at least not impair the other one right? Do you have any other suggestion? Do I have to route something somewhere somehow?

  • MySQL permission errors

    - by dotancohen
    It seems that on a Ubuntu 14.04 machine the user mysql cannot access anything. It is not writing logs nor reading files. Witness: - bruno():mysql$ cat /etc/passwd | grep mysql mysql:x:116:127:MySQL Server,,,:/nonexistent:/bin/false - bruno():mysql$ sudo mysql_install_db Installing MySQL system tables... 140818 18:16:50 [ERROR] Can't read from messagefile '/usr/share/mysql/english/errmsg.sys' 140818 18:16:50 [ERROR] Aborting 140818 18:16:50 [Note] Installation of system tables failed! Examine the logs in /var/lib/mysql for more information. ...boilerplate trimmed... - bruno():mysql$ ls -la /usr/share/mysql/english/errmsg.sys -rw-r--r-- 1 root root 59535 Jul 29 13:40 /usr/share/mysql/english/errmsg.sys - bruno():mysql$ wc -l /usr/share/mysql/english/errmsg.sys 16 /usr/share/mysql/english/errmsg.sys Here we have seen that mysql cannot read /usr/share/mysql/english/errmsg.sys even though the permissions are open to read it, and in fact the regular login user can read the file (with wc). Additionally, MySQL is not writing any logs: - bruno():mysql$ ls -la /var/log/mysql total 8 drwxr-s--- 2 mysql adm 4096 Aug 18 16:10 . drwxrwxr-x 18 root syslog 4096 Aug 18 16:10 .. What might cause this user to not be able to access anything? What can I do about it?

  • Can't access server on LAN new Router

    - by RMDan
    Earlier this week my roommates decided to change the router we are using for our home network. On the old router I had no problems accessing a laptop running Mint Linux over the network(SSH, FTP, and Shared Folders). However I am now not able to connect. I have verified the IP address of my Linux machine has not changed and I have no problems connecting to our NAS(WDMYCLOUD). The new router is a D-Link DIR-868L. PuTTY is giving me a Timed Out error(was giving me a EHOSTUNREACH before). Running Windows 8.1 the connecting laptop, but tried connecting using my phone via SSH did not work either. More information: Can ping the Linux machine from the router but not my computer. Pinging 192.168.0.111 with 32 bytes of data: Reply from 192.168.0.102: Destination host unreachable.

  • An XKB keyboard map that responds to the left and right shift key individually

    - by mbfisher
    First off, excuse my ignorance of X and XKB; I've been trying to hack together a solution in the hope of being able to achieve what I want without requiring a detailed grasp of it. I'm trying to create an XKB keyboard map on Ubuntu 12.04 that allows me to stipulate which of the two shift keys constitutes the Level2 modifier. Specifically, the 4 key should only produce a $ when the right shift is held, not the left. My reading so far: http://www.charvolant.org/~doug/xkb/html/node5.html http://people.uleth.ca/~daniel.odonnell/Blog/custom-keyboard-in-linuxx11 http://www.x.org/releases/X11R7.5/doc/input/XKB-Enhancing.html Lots of searching! I've attempted to define a custom type, and then refer to it explicitly in a symbols map: /usr/share/X11/xkb/types/mbfisher: default xkb_types "mbfisher" { type "RIGHT_SHIFT" { modifiers = None+Shift_R; map[None] = Level1; map[Shift_R] = Level2; }; } /usr/share/X11/xkb/symbols/mbfisher: default partial alphanumeric_keys xkb_symbols "basic" { name[Group1]= "mbfisher"; key <AE04> { type= "RIGHT_SHIFT", symbols[Group1]= [ 4, dollar ] }; }; I'm then selecting the map with the Ubuntu Keyboard Layout GUI. This obviously disables the alphanumeric keyboard apart from the 4 key, but the dollar sign can still be typed with either shift key. I'm conscious of writing a massive question with lots of useless information so I'll stop here; please ask for anything I've missed out. Any ideas?

  • Splitting HDMI sound to 2 devices under Windows 7

    - by Jeramy
    Okay, this is a strange set-up and is frustrating me. I have an HDMI signal from my PC being split to my audio receiver and my HDTV. I need to split it to both so that I can choose to either play audio from the HDTV or from the surround sound speakers in the room. The problem that I am having is in Windows 7, the output is listed under "Playback Devices" and is auto-populated with the HDTV, which only has the option for stereo sound. If I unplug the HDTV from the splitter it will populate with my receiver information and let me set it to 5.1 surround, but as soon as I plug the HDTV back in it reverts. I tried reversing the order of the HDMI cables in the splitter and this seemed to work for a short while, then Windows must have polled the devices again or something because it reverted. It will work as long as Windows identifies the reciever, thereby unlocking the 5.1 surround option, otherwise I am stuck with stereo, which it assumes is all the HDTV is capable of. Is there a way to manually override this and set my own options? Or any other solutions?
