  • Startup script for Red5 on Ubuntu 9.04

    - by user49249
    I am creating startup script for Red5 on Ubuntu. Red5 is installed in /opt/red5 Following is a working script on a CentOS Box on which Red5 is running [code] ==========Start init script ========== #!/bin/sh PROG=red5 RED5_HOME=/opt/red5/dist DAEMON=$RED5_HOME/$PROG.sh PIDFILE=/var/run/$PROG.pid # Source function library . /etc/rc.d/init.d/functions [ -r /etc/sysconfig/red5 ] && . /etc/sysconfig/red5 RETVAL=0 case "$1" in start) echo -n $"Starting $PROG: " cd $RED5_HOME $DAEMON >/dev/null 2>/dev/null & RETVAL=$? if [ $RETVAL -eq 0 ]; then echo $! > $PIDFILE touch /var/lock/subsys/$PROG fi [ $RETVAL -eq 0 ] && success $"$PROG startup" || failure $"$PROG startup" echo ;; stop) echo -n $"Shutting down $PROG: " killproc -p $PIDFILE RETVAL=$? echo [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$PROG ;; restart) $0 stop $0 start ;; status) status $PROG -p $PIDFILE RETVAL=$? ;; *) echo $"Usage: $0 {start|stop|restart|status}" RETVAL=1 esac exit $RETVAL [/code] What do I need to replace for Ubuntu in the above script.

I would like to be able to use them with service as Red hat distributions do. I checked /lib/lsb/init-functions.

  • Winamp has slow /skipping video playback on Windows 7

    - by Roy Rico
    Hello, I have Windows 7 x64 (7600 90-day trial version) and Winamp 5.6 installed. When I play a video in Windows Media Player, the video plays smooth, however when I play a video in winamp, the video is mostly ok when played back at the original size (but not completely), but if I play it back in fullscreen, the playback gets really slow. The video's audio track plays just fine. I have a DELL XPS 420 computer (8GB of RAM) with a Nvidia GeForce 8800 CTS 512 video card. I've updated to the latest drivers. I have the default Windows 7 codecs, and the CCCP codec pack which used to be all I needed under Windows XP to play all types of videos. Are the codecs needed for Windows Y the same? What's going on? UPDATE: As suggested, I turned off Aero and winamp ran just fine again. So I just have to wait for winamp to be rewritten to work with the way Vista/Windows 7 runs? UPDATE 2: Winamp has updated their player, and it works great with Windows 7 now.

  • Windows 8 Fails to install with corrupted graphics

    - by Andy
    I am trying to install Windows 8 Pro Upgrade via the download method on an older PC (07-08). It is a Dell Dimension E521 but it has been upgraded with a 3.0 Ghz Dual Core AMD Processor, 120 GB SSD, and 4 GB of RAM. The Windows 8 upgrade assistant did not detect any issues or concerns with upgrading other than I don't have DVD software installed. The system install Windows 8 but on the first boot, corrupt graphics are present. Eventually, the monitor will go into sleep mode and then roll back to Windows 7 Pro X64 which runs fine. I wouldn't be upset over not being able to install Windows 8, but I already paid for the software since I thought there would be no issues upgrading. The Graphics card in the system is the Geforce 7300LE and it has the latest NVidia drivers for Windows 7 loaded. I saw this solution which is similar to my problem: Corrupt graphics during Windows 8 installation However, I have downloaded Windows 8 and I am not sure how to go about modifying the install that resides somewhere on the hard drive. Thanks in advance for any assistance.

  • Windows Media Center showing Jerky Video on PC

    - by Kris Erickson
    I had to repave my Windows 7 x64 box last week due to a hard drive crash, and for a while everything was running perfectly but now all videos in Windows Media Center are jerky (the sound is fine, they just seem to skip a ton of frames all the time). This is on the local machine, but the same thing happens when I try to stream to my Xbox. The videos all show fine in VLC and Windows Media Player (however exhibit the same problem in Quicktime). I guess I must have installed something recently (in the process of getting all the apps I usually have running on my PC) that caused this but for the life of me I can't figure it out. I have updated to the latest video driver (and then rolled back to the standard Windows 7 driver), I have rolled back all the other drivers that I have installed (I believe). I have uninstalled all the codec packs (I also run TVersity, so I have the TVersity codec pack installed), and I uninstalled TVersity. Nothing seems to help. I have uninstalled windows media center, and reinstalled it from the Programs and Features. I have basically ran out of things to try to fix this, and am almost thinking about reinstalling Windows again. Any suggestions? Edit Specs on the PC (which I figured was unimportant since everything used to work perfectly): Intel Core 2 CPU 6600 @ 2.4 Ghz Nvidia GTS 8800 Built in realtek-audio soundcard 4GB Ram Codecs which are failing: All that I have tried, but at least Xvid, Mpgv (mpeg2 video from a camera), and Wmv (only kinds that I have ready access to).

  • Intel Ethernet Bottlenecking Internet?

    - by Donald Darma
    I'm having trouble with my internet speeds. So I just recent build a pc and everything is fine. I installed the Intel drivers and connected to the internet. It connects but I'm only half the speed I should be getting. My normal speed is 20mbps but speedtest.net is only showing 10. It can't be my ISP (which is TWC if anyone is asking) because my other devices like my laptop and my smartphone are showing 20 down. Heres my system: CPU: i5 4430 HSF: Stock cooler Mobo: Gigabyte Z87MX-D3H GPU: x2 MSI R7950-3GD5/OC BE RAM: Crucial Ballistix Tactical Tracer 8GB dual channel PSU: Silencer High Performance Power Supply 750 Watt 80+ (It's a subdivision of OCZ) HDD: Seagate Barracuda 7200RPM 3TB SSD: Samsung 840 Evo 120 GB Case: Corsair Obsidian 350D Edit: I am using the stock adapter that is on the motherboard. I know for a fact that the cable is good because I used it on my laptop and it ran fine. Its a CAT5E cable. I also ran IPERF and its giving me the same results, 10 mbps.

  • Screen occasionally flashes black when under load, sometimes does not recover

    - by Oak
    I've built a brand new machine, but to my horror my monitor occasionally flashes black for around a second, then returning to normal. This happens under load (watching videos / playing games) but only sometimes; e.g. it doesn't occur in "Batman: Arkham City" but does in "XCOM: Enemy Unknown". When watching videos, it also occurs when not watching them full-screen, and it sometimes even occurs when the machine isn't doing anything, just sitting at the desktop and moving the mouse around. Has anyone ran into this problem and knows of any solution? Additionally, sometimes after the black screen, it won't return to normal, instead turning completely corrupt. In these cases even quitting the application doesn't help, but physically disconnecting and reconnecting the monitor fixes the problem. This problem did not occur on my earlier machine which used the same physical monitor. Additional details: Windows Server 2012, configured as Windows 8, with latest updates installed NVIDIA GeForce GTX 660 Ti, with latest driver installed Ample amounts of CPU and RAM for playing the above games and for watching videos. I've read about similar problems elsewhere but could not find a working solution: http://www.youtube.com/watch?v=Zt00C-HXFbA&noredirect=1 http://www.sevenforums.com/hardware-devices/59126-monitor-flashing-black.html https://eu.battle.net/d3/en/forum/topic/4079098908?page=4 http://www.tomshardware.com/forum/347422-33-screen-flickering-black-nvidia-driver-update

  • Ubuntu network card problem.

    - by Steve Greene
    Hello folks, Several days ago, I installed Ubuntu 9.10 onto my Acer Aspire 3100 laptop, running it alongside Widows Vista as a dual-bootable system. Creation of the Ubuntu boot CD went fine, and the installation onto my hard drive was flawless. Ubuntu opens and behaves as I would expect, except for one little problem. For reasons unknown to me, Ubuntu is not communicating with my laptop's networking hardware, and I have no internet connectivity, it works fine under Windows Vista. Up in the right side of the Ubuntu desktop, I click on the network icon and it does not show a wireless connection at all. At home, where I use a dialup modem, I also see no means of getting online. My modem is an HDAUDIO Soft Data Fax Modem with Smart CP,manufactured by CXT (Conexant Systems Inc., file version 4.0.13.0, and the driver version is 7.58.0.0). I am an advanced computer user, but I am not a programmer. I seek a solution that is user-friendly for normal people, something equivalent to a driver that I can easily install or activate that will allow Ubuntu to see my hardware and get me connected. Can anyone help me over this hopefully-little glitch My processor is a Mobile AMD Sempron Processor 3500+ at 1.80 GHz, 1.50 GB RAM, and a 32-bit Operating System.

  • Compressing and copying large files on Windows Server?

    - by Aaron
    I've been having a hard time copying large database backups from the database server to a test box at another site. I'm open to any ideas that would help me get this database moved without having to resort to a USB hard drive and the mail. The database server is running Windows Server 2003 R2 Enterprise, 16 GB of RAM and two quad-core 3.0 GHz Xeon X5450s. Files are SQL Server 2005 backup files between 100 GB and 250 GB. The pipe is not the fastest and SQL Server backup files typically compress down to 10-40% of the original, so it made sense to me to compress the files first. I've tried a number of methods, including: gzip 1.2.4 (UnxUtils) and 1.3.12 (GnuWin) bzip2 1.0.1 (UnxUtils) and 1.0.5 (Cygwin) WinRAR 3.90 7-Zip 4.65 (7za.exe) I've attempted to use WinRAR and 7-Zip options for splitting into multiple segments. 7za.exe has worked well for me for database backups on another server, which has ~50 GB backups. I've also tried splitting the .BAK file first with various utilities and compressing the resulting segments. No joy with that approach either- no matter the tool I've tried, it ends up butting against the size of the file. Especially frustrating is that I've transferred files of similar size on Unix boxes without problems using rsync+ssh. Installing an SSH server is not an option for the situation I'm in, unfortunately. For example, this is how 7-Zip dies: H:\dbatmp>7za.exe a -t7z -v250m -mx3 h:\dbatmp\zip\db-20100419_1228.7z h:\dbatmp\db-20100419_1228.bak 7-Zip (A) 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Scanning Creating archive h:\dbatmp\zip\db-20100419_1228.7z Compressing db-20100419_1228.bak System error: Unspecified error

  • Capabilities of business and SOHO routers

    - by Q8Y
    I'm currently studying for the CCNA certifications (especially for Cisco routers and configuration). I know that business routers provide more features than SOHO routers, the processing speed and RAM can be enough. Assume I need to connect a number of users through a network (accessing internet, share files, printers, ...). I have a high speed connection to the internet and I already applied QoS. How can I find out how many users such a single (SOHO) router could handle? In my case I'd attach to it multiple switches until I have the number of ports needed. Would everything work well and smoothly with 50 users? What about 300? At which point would I need a business router instead? If I implemented VLAN here, would it make any difference in the performance? When do I really need to use more than one router? (Both SOHO and business) I'm thinking that I may need them only if I want to increase the performance (instead of replacing the existing one) and if I have multiple locations, so in this situation I need to have multiple routers, right? Put differently: Is there is a need to have another router if my business all in one place?

  • keyboard intermittently stops working, even after reinstalling windows 7; possibly a Chrome issue?

    - by neverskipbreakfast
    My keyboard intermittently stops working. Sometimes a couple of keys will work, but usually none. Sometimes if I mash a couple of the ctrl+alt+windows type keys randomly for a bit, the keyboard will let me type one more letter before stopping again. Sometimes the keys will open a program menu, but usually not. I have even completely wiped my machine and reinstalled windows 7; the problem continues. Specs: Intel iMac (early 2006, 2.0GHz, 2MB RAM, 240GB HD) running ONLY Windows 7 Professional, 32-bit (NOT through boot camp) and using a USB keyboard (Saitek Eclipse II.) *Unplugging & reconnecting keyboard does NOT fix it. *Connecting a different keyboard does NOT fix it. That one won't work, either. *Drivers are up-to-date. Removing and reinstalling drivers does NOT fix it. *Restarting the computer does NOT fix it. In fact, when the Windows logon screen appears, they keyboard won't work, and neither will the icon to pull up the on-screen keyboard. Otherwise my mouse can click around just fine. I can only log onto a non-password protected account. *Generally, logging into as different Windows user fixes it. I can then log back on to my main user account and continue work for a few hours until it happens again. *Clearing my Chrome browsing data stopped the problem from recurring for a week or so. *I use Avira free antivirus software, and repeated scans turn up nothing fishy. *I have already REINSTALLED Windows 7 (not just a restore.) The problem returned after 2 days of use. The only thing I suspect is something in Google Chrome -- I used my google account to reload all my previous Chrome extensions, saved data, etc. (Chrome Extensions Installed: AdBlock, Better Google Tasks, DropBox, FB Photo Zoom, Google Mail Checker, StayFocusd.) Any ideas? Any at all?

  • UW-IMAP server, high load for one user

    - by Bruce Garlock
    We have been experiencing a very strange anomaly, with one specific user with our UW-IMAP server. We have about 75 users using the server, and one particular user, who is in about the middle as far as used storage keeps having issues with slow speed. Most of our users all use Thunderbird 2, or Thunderbird 3. Mostly 2, because of the performance issues we have had with 3. This user was on 3, and I downgraded him to 2. The performance has gotten better, but according to the imapd processes on the server, his username is using the most CPU % and CPU time. I've already done all the usual T/S'ing: Started profile from scratch, compacted folders, re-indexed, newer faster computer, etc.. Still, this users' imapd process is always using the most CPU on the server. For troubleshooting, we setup another user which has more usage, folders, etc.. than he does, but we don't see the users process taking up most of the CPU with the imapd process. So, it almost sounds like a particular email may be the culprit, but how can we find it, if thats the problem? This has been going on for a while, and he is a management person, so his patience is about to end. Does anyone have any ideas?

  • mod_fcgi in virtualmin: graceful kill fail, sending SIGKILL?

    - by mgjk
    Yesterday around 1am, our server ground to a crawl. This doesn't happen often, but I'm trying to get to the bottom of it. There is no unusual traffic volume, no unusual processes running, just all of the sudden the server started killing fcgid processes. [Thu Aug 02 01:17:32 2012] [warn] mod_fcgid: process 26460 graceful kill fail, sending SIGKILL ... for as many fcgid processes as we have... CPU idle fell to 0% and I/O seemed to take up most of the load. The issue lasted about 5 minutes. I suspect there was some swap activity, although I'm not sure if it was due to killed processes being swapped in to die, or if it was because some process ramped up memory usage faster than my process watching scripts can see them. The oom-killer wasn't triggered (at least it's not logged), so I think this was Apache for some reason restarting the processes. This is not regular, and nothing obvious appears in cron. Is there a normal Apache process which might cause this? We run dozens of different sites, and it was late at night, so volume was very, very low. (maybe 200 requests in a 10 minute period).

  • Problems Installing slapd On Ubuntu Server 11.10

    - by Zach Dziura
    I know that there's a Ubuntu-specific StackExchange website, but I thought that I'd ask here because it's a server-specific question. If I'm wrong in my logic... Well, you people are better at this than I am! O=) On with the show! I'm in the process of installing Oracle Database 11g R2 Standard Edition onto Ubuntu Server 11.10. I found a guide on the Oracle Support Forums that walks you through the process fairly easily. Unfortunately, I'm running into issues installing one particular dependency: slapd. When I go to install it, I get this error message: (Reading database ... 64726 files and directories currently installed.) Unpacking slapd (from .../slapd_2.4.25-1.1ubuntu4.1_amd64.deb) ...

The error messages seem straight forward enough, but I have no idea how to debug this. Can anyone offer some assistance? Again, if I'm asking in the wrong place, I apologize. If I'm indeed asking properly, then thank you for any and all help!

  • Windows 7 64-bit Google Chrome Makes Desktop Unresponsive

    - by Meengla
    For the past 1-2 weeks my desktop becomes unresponsive sometimes. The problem seems to happen as I load a page in Google Chrome; it could be any page though today it happened when I tried to load a page with Flash content in it. The problem is not consistent and there is no pattern. I can do a virus scan using some software (not antivirus installed--never needed that) but I strongly suspect it is some software I installed or some Windows Update. This is a very powerful Dell Optiplex 990 with 16GB RAM, so Memory shouldn't be an issue. When the problem happens the cursor becomes spinning even over the taskbar and control alt delete takes a long time. Eventually I get a message that 'this program is not responding' with end/close and 'cancel' icon. But repeated end or cancel does nothing. Then the menu for ctrl alt del comes up. The rest of the applications keep running fine though I can't get to them because the cursor is the wait-cursor. What is happening? How can I find what exactly caused the problem? Thanks.

  • RAID 6 that can read with least 1000 Mbit/s?

    - by Diblo Dk
    I purchased a Dell PERC 6/i which I expected to be able to read with 1000 Mbps. There is not much to do now, but there are some things I wanted knowledge about for another time. I have configured it with four 2 TByte drives and RAID 6. It have 256 MByt ram and transfer rate of 300 Mbps. The benchmark test showed: Min read rate: 136.3 Mbps Max read rate: 329,6 Mbps Avg read rate: 242,2 Mbps What could I had done to get at least 1000 Mbps? Is it normal for internal and external RAID controllers to have a lower transfer rate eg. 300 Mbps? (I did not noticed at the time that it was not 3 Gbps) How would a RAID 10 had performed compared to RAID 6 or 5? Would it have been better to use software RAID (Linux) with the internal 3 Gbps SATA controller? UPDATE: The drives is SATA III 6 Gbps. http://www.seagate.com/files/staticfiles/docs/pdf/datasheet/disc/desktop-hdd-data-sheet-ds1770-1-1212us.pdf (2TB)

  • Hadoop streaming job on EC2 stays in "pending" state

    - by liamf
    Trying to experiment with Hadoop and Streaming using cloudera distribution CDH3 on Ubuntu. Have valid data in hdfs:// ready for processing. Wrote little streaming mapper in python. When I launch a mapper only job using: hadoop jar /usr/lib/hadoop/contrib/streaming/hadoop-streaming*.jar -file /usr/src/mystuff/mapper.py -mapper /usr/src/mystuff/mapper.py -input /incoming/STBFlow/* -output testOP hadoop duly decides it will use 66 mappers on the cluster to process the data. The testOP directory is created on HDFS. A job_conf.xml file is created. But the job tracker UI at port 50030 never shows the job moving out of "pending" state and nothing else happens. CPU usage stays at zero. (the job is created though) If I give it a single file (instead of the entire directory) as input, same result (except Hadoop decides it needs 2 mappers instead of 66). I also tried using the "dumbo" Python utility and launching jobs using that: same result: permanently pending. So I am missing something basic: could someone help me out with what I should look for? The cluster is on Amazon EC2. Firewall issues maybe: ports are enabled explicitly, case by case, in the cluster security group.

  • I cannot connect to home server after a few hours

    - by Iago
    I have an old PC and I decided to revive it. A LAMP (for my own use) and a P2P server (torrent and e2dk). My old PC is an AMD Athlon XP (1400 MHz) with 384 Mb of RAM First of all I installed Ubuntu Server 11.10, SSH, FTP, SAMBA and LAMP. With this configuration my home server works well, with no problem. Then I went to the P2P server and I tried rTorrent and then uTorrent Server Alpha. And here is my problem. After a few hours (maybe 10 hours, or maybe 30 hours) with the torrent app running (rTorrent or uTorrent) I lose the connection to my home server. That is, I cannot access via ssh, I cannot access the apache server, etc. but I can ping the home server. It seems that the server freezes and all I can do is reboot the server physically. So, I have two questions: What is the problem? and How can I solve it?

  • Poor performance on IIS7, only on Windows Server 2008, fine on Windows 7?

    - by user32005
    Hi, I'm new to IIS7 but have experience with other versions. I've been working on an application that works great in a dev environment (as always) but when I push it to a windows server 2008/IIS7 box performance takes a noticeable hit. The dev environment is Windows7/IIS7. The configuration in IIS is the same on the dev box as the server. I've tried all sorts of things to try and find a reason for this but I cant come to any conclusion. I've ruled out database problems on the live box as all data is cached after the first request. I've confirmed this to be true and made sure there is no additional database traffic. I've ruled out network issues with a combination of monitoring requests with fiddler and local debugging on the server. Whenever the code runs on the server there seems to be a performance issue. The server: Intel Core 2 Quad CPU Q6600 @ 2.40ghz with 2gb RAM. I know this is not fantastic but I was expecting it to at least perform as well as my dev environment (which is running much more on a lower spec). The CPU using peaks at under 60%, and memory usage is less than half of the available. I've enabled failed request tracing and most of the time is spent in a custom HttpModule, this module works to handle every request, I cant get any more detail as to what within the module may be causing the problem. Any ideas, I've been pulling my hair out for days now. Thanks

  • SQL Server Installation: Is it 32 or 64 bit?

    - by CapBBeard
    Hi, Recently I was performing an OS upgrade on one of our DB servers, moving from Server 2003 to Server 2008. The DBMS is SQL Server 2005. While reinstalling SQL on the new Windows installation, I went to another of our DB servers to verify a couple of settings. Now, I always thought this second server was Server 2003 x64 + SQL 2005 x64 (from what I'd been told), but I now have my doubts about this. I now suspect that it is in fact only 32 bit SQL, however I'd like to verify this. Here's some details: The OS is definitely 64 bit. xp_msver shows Platform as NT INTEL X86 SELECT @@VERSION shows Microsoft SQL Server 2005 - 9.00.4035.00 (Intel X86)... However sqlservr.exe is not shown with '* 32' in taskmgr, does anyone know why this is the case, if it is in fact 32 bit as claimed? Despite this, it does seem to be running out of the x86 program files folder. If I do the same checks on a confirmed 64 bit installation, it does give back the expected 64 bit readings, which can only prove that this server in question is only running in 32 bit. Now, that being the case, the question arises about how much memory this '32 bit' install can use. Task manager reports about 3.5GB memory usage for sqlservr.exe (The server has 16GB physical). I suspect that AWE has not been configured at all, and therefore the server will be significantly under-utilised (remembering that the OS is 64 bit) if SQL is simply using a 32bit address space. Is this assumption correct? I feel the server should have SQL reinstalled as 64 bit in order to fully utilise the hardware platform, however it is currently heavily in production; this will be no easy task. I suspect we may just have to configure AWE correctly and let it be for the time being (Unless this is a bad idea?). I apologise that this question is a little vague/lost; I'm no SQL expert, just trying to get a handle on what's going on here.

  • Merely installing PHP5 causes my AWS Ubuntu server to die minutes later from a massive CPU spike

    - by Mark Amery
    I have an AWS server with Ubuntu 11.04 as the OS that is running an Apache2 webserver (incidentally Python-based and using Django). We recently needed to add support for php5 to let us use a third party PHP library (incidentally for serving minified versions of js and css files). However, for no reason any of us can discern, if we simply run sudo apt-get install php5 on the server, then the install appears to finish successfully but, without us taking any further action (including not yet running sudo apt-get install libapache2-mod-php5, which I think would be the next step for us if everything worked), or actually running any PHP scripts on the server, a few minutes later the server becomes impossible to connect to, and looking at the 'Monitoring' tab for the server in the EC2 Management Console reveals that a while after the installation, CPU usage spikes to 100% and stays there permanently (until we reboot the server from the AWS Console). After rebooting, the server also reliably dies within a few (between 0 and 10) minutes. We restored the server to a pre-PHP state from an AMI Image, observed that it was stable, and then tried installing PHP5 again and observed the server die in exactly the same way, so we're pretty much certain that installing PHP5 is what causes the symptoms. What on earth could be causing this behaviour, and how can we get PHP installed on the server without it dying?

  • Max. Temp. on Intel Burn Test for Stock Dell Precision T3500

    - by HK1
    I'm troubleshooting an issue on a Dell Precision T3500. As part of my troubleshooting I've decided to try running a stress test using Intel Burn Test software. This machine is a stock configuration with 12GB of RAM and a Xeon W3670 processor (nothing overclocked). When I run IBT using the standard mode, SpeedFan reports a processor temperature in excess of 80C. I've seen numbers as high as 90C but even at that temperature the machine does not become unstable or crash. However, it seems way too high. This processor has a TCase of 67.9C according to Intel's website. I'm guessing that means I'm in the danger zone any time I go over that temperature. I've checked the cooling system and everything looks fine. I've even took out the heat sink and reinstalled it with new thermal compound. This did not appear to make the problem better or worse. Is there a discrepancy somewhere here in the way temperatures are measured or displayed? I've also tried using HWMonitor from CPUID and it reports the same temperatures. Should I just let the Standard Test go and disregard the temperature outputs?

  • Isolating a computer in the network

    I've got a small network and want to isolate one of the computers from the whole network. My Network: <----> Trusted PC 1 ADSL Router --> Netgear dg834g <----> Trusted PC 2 <----> Untrusted PC I want to isolate this untrusted PC in the network. That means the network should be secure against : * ARP Poisoning * Sniffing * Untrusted PC should not see / reach any other computers within the network but can go out the internet. Static DHCP and switch usage solves the problem of sniffing/ARP poisoning. I can enable IPSec between computers but the real problem is sniffing the traffic between the router and one of the trusted computers. Against getting a new IP address (second IP address from the same computer) I need a firewall with port security (I think) or I don't think my ADSL router supports that. To summarise I'm looking for a hardware firewall/router which can isolate one port from the rest of the network. Could you recommend such a hardware or can I easily accomplish that with my current network?

  • I can't get my PC to start up by a normal way.

    - by ssice
    I couldn't write a more accurate title. I am just unable to start the computer by pressing the Power On button. I checked the Power Supply and it seems to give good voltage values in every pin. And this is not a BIOS malfunction because of bad overclocking or anything that may come to your mind. And I will tell you why. It happens that EPS (or any ATX-based) power supply has the ability to be powered-on by the Motherboard by jumping the 13th pin of the 24-pin-ATX-connector to COM/GND. I did it, after pushing the power on button (without any visual response) and, pwhaa! The machine turned on. I was able to read (and even write, if I wanted) BIOS values and then start any OS installed. Machine starts, so it's not any kind of misconfiguration. It seems some hardware related. I am able to power the machine on only if I already pushed the power on button. Though pushing it without jumping the 13th pin to ground for a second does not power the machine. Of course, jumping the pin without pushing the power on button does not tell the motherboard anything, so the computer would not start up either. It's as if the logic that connects the power button with the 13th pin derivation to GND was unable to be activated. What can be the issue? How can I solve it? My configuration is as follows: CPU: AMD Phenom 9850 X4 Black Edition MB: ASUS Formula II AM2 RAM: 2x2GB Corsair Dominator 5-5-5-15 2T @ 1066MHz DDR2 Tested also with only 1 module GPU: 2x XFX nVIDIA GeForce 9600 GT XxX Alpha Dog Edition @ Core: 540Mhz [SLi] Power Supply: Xilence 700W (ATX 12V 2.3 / EPS 12V 2.92 compatible) PS: I know the machine is like 2 years old. I hardly use it now, but my parents do.

  • Enterprise class storage best practices

    - by churnd
    One thing that has always perplexed me is storage best practices. Filesystems brag about how they can be petabytes or exabytes in size. Yet, I do not know many sysadmins who are willing to let a single volume grow over several terrabytes. I do know the primary reason behind this is how long it would take to rebuild the array should a drive fail. The more drives in a single LUN, the longer this takes and the greater your risk of losing another drive while the rebuild is taking place. Then there's usage reasons. Admins will carve out a LUN based on how much space they think needs to be allocated to the project. It seems more practical to me for the LUN to be one large array and to use quotas. I understand this wouldn't satisfy every requirement (iSCSI), but I see a lot of NAS systems (NFS) managed this way. I also understand that the underlying volumes can be grown/shrunk as needed quite easily, but wouldn't it be less "risky" to use quotas rather than manipulating volumes and bringing possible data loss into the equation? There may be some other reasons I'm missing, so please enlighten me. Can we not expect filesystems to ever be so large? Are we waiting for the hardware to get faster to cut down on rebuild times?

  • How can I install iTunes in such a way that it can't put any "hooks" or helper programs on my computer?

    - by Joshua Carmody
    I'm buying a new iPad, which means I must once again install iTunes. I've not used iTunes in more than 6 months, since I bought a new computer. I don't like iTunes, but I can live with using it to buy/manage media and sync my Apple devices when the program is open. What I would like to do though, is find a way to install iTunes in such a way that it has absolutely no effect on my system when it is closed. iTunes normally installs several helper programs such as iTunesHelper.exe, and the Bonjour service. These programs run in the background when iTunes is closed. You can force-close them, or remove them from your setup files, but iTunes will often put them right back when you run it. I know these programs are mostly harmless, but they have at times caused issues such as iTunes spending system resources trying to catalog media files or drives connected to VPN, or other issues. At best they're just one more small background process eating up a small piece of my CPU time and RAM. How can I run iTunes without letting it get it's "hooks" into my system? One thought I had is that I could create a Windows user account just for iTunes, and deny it admin privileges. Then if I installed iTunes using that account maybe anything it installed wouldn't affect the "main" account on my PC? But I'm not sure if that would work.... Failing that, maybe some kind of virtualization software or sandbox I could install it in? I'm open to any suggestions. My system is an Intel-based PC running Windows 7 Professional 64-bit. Thanks!
