  • How can I stream audio signals from various devices/computers to my home server?

    - by Breakthrough
    I currently have a headless home server set up (running Ubuntu 12.04 server edition) running a simple Apache HTTP server. The server is near an audio receiver, which controls a set of indoor and outdoor speakers in my home. Recently, my father purchased a Bluetooth adapter, which our various laptops and cellphones can connect to, outputting the music to the speakers. I was hoping to find a solution that worked over Wi-Fi, namely because it won't cost anything (I already have a server with an audio card), and it doesn't depend on Bluetooth. Is there any cross-platform (preferably free and open-source) solution that I can use which will allow me to stream audio to my home server, over my home network, from a wide variety of devices (laptops running Windows/Linux or cellphones running Android/BB/iOS)? I need something that works at least with Windows and Android. Also, just to clairfy, I want something that simply allows devices to connect to my server and output an audio signal without any action on the server end (since it's a server hidden away near my receiver). Any subsequent connection attempt should be dropped, so only one device can be in control of the stereo at once.

  • Thin client - cloud machine - to run via iPad, iPhone, most Androids etc

    - by Carl Lindberg
    I'm tired of having a laptop macbook that breaks down or having files that I need to sync via dropbox etc all the time via the machines to different OS installations. It sucks. I want a thin client where I can login on any machine - my iPhone, PC desktop, iPad etc to one running machine. I would like to replace a modernly powerful desktop iMac with a thin client running via my iPad. I will connect the iPad with a keyboard/mouse too so you get the idea. But I want to be able to use some of the Android phones as well (I guess most Android phones today has a good enough performance/resolution etc to run a thin client). Of course it has to be able to have input/output in sound. Printing can be solved by PDF/emailing etc - so no direct communication to the printer ports to USB etc is necessary. Is there such a service today? It should cost somewhere under something like $40/ month. I will run stuff like CPU heavy duty ableton for music production, xCode for making iOS apps, some games etc. And on the thin client also run virtual machines. VM of Ubuntu and Windows.

  • Simple way to set up port knocking on Linux?

    - by Ace Paus
    There are well known benefits of Port Knocking utilities when utilized in combination with firewall IP table modification. Port Knocking is best used to provide an additional layer of security over other tools such as the OpenSSH server. I would like some help setting it up on a ubuntu server. I looked at some port knocking implementations here: PORTKNOCKING - A system for stealthy authentication across closed ports. IMPLEMENTATIONS http://www.portknocking.org/view/implementations fwknop looked good. I found an Android client here. And fwknop (both client and server) is in the ubuntu repos. Unfortunately, setting it up (on the server) looks difficult. I do not have iptables set up. My proficiency with iptables is limited (but I understand the basics). I'm looking for a series of simple steps to set it up. I only want to open the SSH port in response to a valid knock. Alternatively, I would consider other port knocking implementations, if they are much simpler to set up and the desired Linux and Android clients are available.

  • Two different subwoofers aren't working on my machine or my phone

    - by Philluminati
    I have speakers that come with my computer. Two small desktop speakers and a subwoofer with a base volume control on the back. It's worked for years. I was listening to Spotify on my speakers as loud they would possibly go and with the base turned up to max and suddenly the subwoofer stopped working. I've plugged the speakers into my Android HTC Desire Z handset and again, the desktop speakers play music but the subwoofer doesn't (even after fiddling with the volume control). So I figured I'd broken it. I went to Amazon and bought a replacement one. I bought this one: http://www.amazon.co.uk/dp/B002N46YD8/ref=pe_217191_31005151_dp_1 but it doesn't work either, on either my desktop nor my Android phone. I had a play with alsamixer and the LFE and center controls are switched on and the speakers are okay... but still no base. Am I unlucky enough to bought a new subwoofer which is already broken out of the box or is there something else which is wrong and I could look into please? Are there any other tests which I could perform to see if the problem is me or not?

  • Windows 7 Paging file apparently not being used

    - by Daniel F.
    I'm running Windows 7 Home Premium 32bit on a mobo with 24GB RAM. Of those 24GB, 20GB are assigned as a RAMDISK via ASRock XFastRAM. This RAMDISK has the drive letter X assigned to it. On X:\ I'm storing the temporary files folder, as well as pagefile.sys. Pagefile.sys has 6GB of size. The X:\ has usually around 14GB free space, so the temporary files are negligible, it's mostly the browsers which are storing their caches on there. Now my issue is that Firefox is crashing a lot on me, no error message pops up, but I know that this is because it's out of memory. I could kind of live with that, but now that I switched from using Eclipse to Android Studio, I know that I'm in trouble, because Java isn't capable of allocating, and Android Studio, together with the Java instances it launches, is quite a memory hog. So I tried to figure out what's wrong, and apparently Windows isn't swapping out memory onto the paging file. While my applications are crashing (firefox) / not starting (java vm's), the paging file is only using constantly around 15% of its size (checked with the performance monitor). 15% equals to 1GB aprox. I know that the correct solution would be to switch to 64 bit Windows, but I had to use the 32 bit version because of driver issues which I had about two years ago, and I guess that I'll have them again if I reformat and install the 64 bit version. Also, the machine is running quite stable, the only issue is the memory, so I'd like to use it as it is (as the apps are installed and configured) Is there a way to make Windows use the paging file more efficiently? None of my processes require more than 1GB, I'd just like it to swap out some seldomly used stuff, like GoogleCrashHandler.exe and stuff like that in order to have "more physical memory avaliable". Is that possible?

  • I'm having trouble getting my server to appear online.

    - by JMRboosties
    Total newb question I'm sure. First I had installed WAMP (http://www.wampserver.com), and I was able to access my pages from other computers in my router network, and the virtual device used to debug Android programs (the purpose of my having a server). This functionality failed, however, at some point over these past few days. While my own browser displays the pages just fine, other computers, my Android phone (on our room's wifi), and my virtual device are no longer able to connect to my pages. I had not made any changes in the settings. I uninstalled WAMP and installed EasyPHP. However, the problem was not resolved. I know this is rather vague, but does anyone here have an idea of what may have happened? I forwarded both port 80 (I know its the default HTTP port, I did it just to be safe), and now port 8888 which EasyPHP uses. I turned my firewall on my hosting computer off for good measure. I cannot access my pages from neither remote computers or computers using my router. Any ideas you may have on how to resolve this would be awesome, thanks a lot. And if you need anymore info please tell me.

  • Does a cable / adaptor for my needs exist? (photos)

    - by Evan
    I recently bought a UPS, however, the only outlets take this sort of connector: But, the other end of the cables is like this (right): The thing is, I really need to connect it to a power bar, so I need a cable that has one end like in the first photo, and the second end like this (right side): I've searched around for quite a while, and asked at a few shops, but cannot seem to find a cable that will fulfill this purpose. This seems crazy to me, as I would think that a UPS wouldn't only be able to be attached to devices that take the relatively obscure output seen on the right side of the second image I posted. Do I need to buy another UPS that has the proper connectors?? Please help!!

  • MS Windows Server 2008R2 slow file copy, slow network connection

    - by MattrixHax
    i just setup a windows 2008R2 standard server, with the only installed app being Hyper-V, and only 1 windows XP VM is running. Whenever i try to copy a file from my windows 7 laptop over to the 2008R2 server machine's admin shares ( \\servername\c$ ) the files start transferring around 60mb/s and then drop to around 5mb/s. My windows 7 machine and the server 2008 machine are both in WORKGROUP (no domain here). when i try the same transfer to our server 2003 box the transfer speeds are fine. tried disabling autotuning (netsh interface tcp set global autotuninglevel=disabled) as well as turning off the checksum offload to the adapter (tx and rx) - i still see strange packet errors (bad header checksum) using wireshark and just cannot seem to track down what the issue is - over 1 hour to transfer 4gb of files from 1 server to another that are on the same GB switch is just crazy.... any ideas would be greatly appreciated!

  • Need help trouble shooting high CPU usage by PHP-fpm

    - by user432506
    There is a problem that is driving me crazy. After the day I tried to fix the CPU usage problem of my VPS, the CPU load has grown from 60% to 150%, and I have no idea what causes the problem. Please help me. I had installed a copy of mediawiki on a Linode 1024. The wiki is running on Niginx + PHP-fpm + MySql. The wiki doesn't have much traffic, only around 4000 requests/day, mostly from Google and Bing bots. It had been using around 60% (of total 400% on the Linode) of the CPU before. I thought it was a bit high, so two day ago, I was trying to fix the problem (not knowing what was waiting for me). I did nothing but added a new empty line to wiki's configure file, which would change the modified time of the configure file, and then all the cached page files would be set invalidated. I had done that before, and that would cause high CPU usage, but normally it would take only hours to let things back to normal again. Not this time, my CPU usage has been around 150% for more than two days. It is php-fpm using most of CPU reassures. Using 100% of three cores is not rare. I hadn't seen that before. There are other sites on the Linode, but it should be the wiki. Because if I offline the wiki, CPU usage will drop back to around 40% soon. The day I also duplicated php-fpm.conf, and opened it, but didn't changed it. I have no idea what I did wrong. I here ask for help to save myself from being crazy!!! It is php-fpm. Is there a way to find out what is it doing? I mean like which scripts are related and what function codes are running? top: top - 06:34:33 up 10 days, 4:23, 2 users, load average: 1.10, 1.24, 1.37 Tasks: 76 total, 4 running, 72 sleeping, 0 stopped, 0 zombie Cpu(s): 61.1%us, 3.1%sy, 0.0%ni, 32.8%id, 2.9%wa, 0.0%hi, 0.0%si, 0.1%st Mem: 1028684k total, 945192k used, 83492k free, 89580k buffers Swap: 524284k total, 18084k used, 506200k free, 530380k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 26721 www-data 20 0 208m 54m 34m R 99 5.4 0:09.07 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26592 www-data 20 0 207m 45m 26m R 91 4.5 0:12.77 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26706 www-data 20 0 196m 43m 34m S 47 4.3 0:15.19 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26583 www-data 20 0 197m 45m 35m S 33 4.5 0:19.08 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26787 www-data 20 0 206m 36m 18m R 25 3.7 0:00.41 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26661 www-data 20 0 207m 46m 26m S 13 4.6 0:19.87 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 1971 mysql 20 0 155m 57m 3952 S 8 5.7 383:57.81 /usr/sbin/mysqld 242 root 20 0 0 0 0 S 1 0.0 0:51.36 [kworker/3:1] 5711 root 20 0 139m 95m 580 S 1 9.5 0:41.30 /usr/local/bin/memcached -d -u root -m 128 -p 11211 19463 root 20 0 190m 3984 1284 S 1 0.4 0:02.66 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 29100 www-data 20 0 10928 5540 820 S 1 0.5 4:49.05 nginx: worker process vmstat 30 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 16912 81456 90784 554172 0 0 4 6 3 2 11 1 87 1 0 0 16912 78036 91000 555356 0 0 38 34 1397 375 12 1 87 0 4 0 16912 31776 91528 557508 0 0 78 42 3197 487 45 1 52 1 1 0 16912 83356 91768 558576 0 0 35 56 2608 449 32 1 67 1 1 0 16912 81548 92040 559720 0 0 41 31 1243 432 8 1 91 1 2 0 16912 53056 92332 562744 0 0 105 33 2013 581 17 1 81 1 2 0 16912 73236 92552 564844 0 0 68 36 1968 615 16 1 82 1 0 0 16912 91612 92904 566676 0 0 69 35 1845 692 13 1 85 1 1 0 16912 71248 93180 568428 0 0 58 33 1952 604 15 1 82 1 1 0 16868 55952 93516 572660 1 0 144 42 1801 637 12 1 86 1 2 0 16868 48324 94416 577844 0 0 189 66 2058 702 17 1 80 2 1 0 16928 58644 94592 578184 0 2 160 49 2578 723 25 1 70 3 5 0 16928 22600 94980 580568 0 0 89 32 1496 361 13 0 85 1 0 0 16988 49256 94500 576396 0 2 41 37 1601 426 14 1 85 0 5 0 18084 24336 86032 502748 0 37 83 68 2989 562 42 1 56 0 1 0 18084 123604 86376 506996 0 0 118 41 2201 573 22 1 76 1 2 0 18084 126984 86752 508876 0 0 64 53 1620 490 13 1 85 1 2 0 18084 103104 87148 510768 0 0 71 37 2757 602 33 1 64 1

  • Cisco ASA bonding/teaming/port-channel capabilities

    - by Antoine Benkemoun
    Hello, This seemed to me like a really simple question that I would be able to answer by myself but I have not been able to find any info on this subject. I have a Cisco ASA 5510 which has 4 FastEthernet interfaces. I was wondering if it would be possible to use 2 or 3 of these interfaces as a port-channel in order to agregate bandwidth for multiple VLANs. I have found no info on the Cisco website nor on Google. Is this just a stupid/crazy idea or am I missing something ? Thank you in advance for your help, Antoine

  • Shared Excel WorkBook is locked by another user

    - by Simone
    I’ve been trying everything; this is the last chance I have. I moved folders and files from an old Windows Server 2003 File Server to a new FS (Win Server 2008 R2) with DFS and ABE enabled. Now, a specific Shared Excel file is driving me crazy, out of a sudden, lots of times per day, users are getting the following error while opening that file: Filename.xlsx is locked for editing by ‘another user’. Open ‘Read-Only’ or, click ‘Notify’ to open.. I’ve already followed this, with no joy: http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/2012/05/14/the-definitive-locked-file-post.aspx In any case, I strongly think this is not client-related, since it never gave that problem in the past with Windows Server 2003. I’ve found and followed many other solutions, nothing. The users are all utilizing Office 2010 on Windows 7 machines, besides a few users who are still on Windows XP machines. I appreciate any help, thank you!

  • RAR Password recovery / hash extraction on Mac OS X

    - by Josh K
    I'm running Mac OS X 10.6.2 and have been handed a couple of old files that need to be extracted. Old backups or finances or bills I believe. They are RAR files, and password protected. Is there a way to extract the hash from these files so I can feed it into John The Ripper or Cain and Abel? Edit I have downloaded cRARk, but unfortunately nothing I have (SimplyRAR, RAR Expander, The Unarchiver) will extract it without a password. Can someone verify that I'm crazy and there is no password on the Mac version?

Also, when I try to open http://webapp-at-port-500, I get the error saying that the webpage cannot be found. Could anyone please help me, it's driving me crazy. Thanks.
