• SPAN/Port mirroring on Linksys switch

  - by Bastien974

  Hi all, I'm trying to deploy a Snort box in my LAN. I have a Linksys SRW248G4 and trying to configure Port mirroring so that Snort can listen everything on the network in promiscuous mode. So in ADMIN / Port Mirroring, I have 3 things: Source Port (e1,...e48, g1...g4) Type (Rx, Tx, Both) Target (e1...e48, g1...g4) Last time I played with it, I killed all traffic on the switch, I had to reboot it several times... so now I'm asking question before: Do I need to configure each Source Port (from 1 to 48) to forward to the single promiscuous port ? 48 rules !? Is that correct ? Thanks !

• Virtual box - How to add disks and move var, opt and home to them?

  - by Jarrod Roberson

  I created a CentOS 5.6 Guest OS Virtual Machine. I made the first disk 10GB, I am rapidly outgrowing it. It was suggested that I make disks for my /var, /opt and /home directories and move them so I can better manage the disks for backing up and what not. This sounds like a good idea. I know how to create the disks in Virtual Box. I have dug around Google and the internet in general and all my attempts at doing this have failed. Snapshots are awesome! I can get the drives fdisked, and I have had limited success mounting them to /mnt/var, /mnt/home and /mnt/opt, but even in single user mode ( init 1 ) I can't get the entire contents of the directories to move over, and then the machine won't reboot correctly. cd /var cp * -ax /mnt/var The /var directory in particular is not wanting to move everything to the new location. How do I format, mount and move the /var, /opt and /home to my new disks?

• IOGEAR KVM cannot reset admin account

  - by George Horlacher

  According to the manual you can do a cold reset by holding the reset button in for 3 seconds. This does seem to reset it but the username and password are not reset... I've tried the keyboard hotkeys - Num-Lock and minus sign (-) to get into hotkey mode and then use the "r" and "" to reset to factory defaults but that doesnt seem to do anything either. It just reverts to User1. I'm not sure what the default admin username should be but admin doesnt seem to work I need to get to the admin menu to name the ports but cannot get access. Any ideas? Using GCS1758 manual with no luck.

• Hyper-V 2012 and P2000 SAS SAN

  - by user155950

  Hi I am having major problems setting up a Hyper-V 2012 cluster on a P2000 SAS SAN. Running System Center VMM 2012 SP1 I am unable to see any storage to create my cluster. Has anyone had experienced anything similar? Under fabric and storage I can't add the P2000, all I can do is use storage spaces in server manager to create a storage pool and virtual disk. This allows me to create a file share which I can add to VMM but I still can't see any disk to create a cluster. I am just about at the point where I want to tear my hair out wipe the servers and stick VMware on them because I know it works as I have set several systems up like this in the past. The Hyper-V servers can see the storage and in server manager on my management machine it seems to know both servers can see the same disk. VMM is running on the same machine and it can't see any disk. Help..... Thanks Mike

• Mapped commands in VIM starting with a Comma

  - by Boldewyn

  In my .vimrc, I defined this line: map ,ps <Esc>:!ps<Space>-a<CR> The mapping is set (which I controlled via :verbose map ,ps while inside vim). There is nothing else mapped to the comma. However, if I type the command in command mode, nothing is displayed in the status bar, the comma is ignored, the p movement and the s insert are triggered. (I.e., VIM reacts, as if there was no command ,ps.) Is there any magic that I have overlooked in enabling comma-started mapped commands?

• Set Display Refresh Rate in OSX w/o External Utilities

  - by codedonut

  I have an iMac and an LG Flatron connected as a secondary monitor. The recommended resolution for the flatron is 1680x1050 @ 65.290 Hz (horiz), 59.954 Hz (vert). For some reason, OSX is choosing a slightly different set of scan rates and this is currently my best guess of why the monitor goes into power saving mode when connected to the iMac (but works fine on a PC). Now, I resolved this by installing switchResX and fudging the scan rates according to the specs in the manual. But how does one change these rates w/o 3rd party tools? Which config files need editing? Thanks

• bluetooth doesn't turn off during sleep in Windows 7

  - by lajos

  I have a Bluetooth USB dongle on a Windows 7 laptop. I did not install any Bluetooth drivers, so I assume that the device is using the Microsoft stack. When the computer goes to sleep, the Bluetooth adapter stays on. I don't want Bluetooth devices to wake the computer, so I want sleep to turn off the dongle, but I can't find power management options for Bluetooth in the Control Panel and Device Manager. I also have an issue where the computer doesn't reach full sleep mode, I'm hoping that turning Bluetooth off will solve that problem, too. How can I turn off Bluetooth during sleep?

• Winlogon.exe causes C++ runtime error

  - by Evan

  Recently I've become unable to log into my Dell Precision M2400. It uses the Dell Controlpoint login GUI instead of the typical windows one, and has now started giving me a runtime error on winlogon.exe that ends with a c000021a BSOD. I have tried running through safe mode and a restore to the last known good setting with no success. Unfortunately by BIOS password is locked and the one IT guy with the password is on vacation and unreachable until after I leave for a business trip. Is there anyway to bypass the Dell logon screen and get to the default windows one? Thanks.

• Is there a work around to configure brightness or color on a DisplayLink monitor?

  - by shaneykakes

  I run 3 monitors in addition to my laptop display at work - two of the monitors are using DisplayLink adapters. I've always thought that all my displays were too bright (and possibly give me headaches?) - even after I reduced their brightness as far as possible using the monitor menus and the nvidia software control panel. Recently I installed f.lux - I love it's "halogen" color profile which has improved my life considerably. The problem is that f.lux has no effect on/will not adjust the color & brightness of my two DisplayLink monitors. F.lux has a faq (#4 under troubleshooting) that addresses this - saying DisplayLink has no support for color calibration so f.lux only works with monitors "directly connected to your computer". Does anyone know of a work around? Specifically a way to use windows color management/profiles (or some other software) to adjust the brightness/color tone of DisplayLink monitors? Thanks in advance!

• Virtual PC - Display Issue with Ubuntu Server

  - by Christopher R

  Hi Everyone, I just did a clean install of Ubuntu Server 9.04 in Virtual PC on the Windows 7 RC, and it seems to be having a bit of an issue with the virtual machine's display adapter. I've tried setting a VGA flag in the GRUB configuration to no avail. This is a guess, but I think it has something to do with the color console mode that gets enabled by default at boot time. The system starts booting just fine (i.e. the console looks "normal" when I'm asked to enter an LVM passphrase, etc.), but then the display goes wonky after a few seconds and I end up with this. Typing commands in bash works just fine: it's not like the system is frozen or anything, I just can't see anything that I type. The console looks exactly the way it does in the image below.

• what might cause a print error in perl?

  - by Mark J Seger

  I have a long running script that every hour opens a file, prints to it and closes the file. I've recently found very rarely, the print is failing, not because I'm testing the status of the print itself but rather due to the fact of missing entries in the file until the system is actually rebooted! I do trap for file open failures and write a message to syslog when that happens and I'm not seeing any open failures so I'm now guessing it may be the print that is failing. I'm not trapping the print failures, which I suspect most people don't but am now going to update that one print. Meanwhile, my question is does anyone know what types of situations could cause a print statement to fail when there is plenty of disk storage and no contention for a file which has been successfully opened in append mode?

• windows service "soft link"

  - by fred smith

  I would like to be able to have a nice management tool to allow the rollout of different versions of a windows service over time. for example I would like to deploy my software (windows service) in version numbered folders, e.g. c:\wss\v1.0 c:\wss\v1.1 etc however I dont want to have to reinstall the windows service each time but rather would like to be able to easily point the windows service manager to the new folder. Are there tools to get this done? NB: I have used Windows Junctions before (from sysinternals) however I am wondering if there is a nice GUI tool to do this.

• Installing isolated instance of MySQL on Windows using silent install with .msi

  - by Abram

  I'm trying to write an installer for an internal application we wrote. After it installs our application it then installs MySQL using the .msi installer in silent mode. I specify the install dir and data dir to that of a directory within my application's install directory, such as: msiexec /i @@MYSQL_INSTALLER_FILE@@ /qn INSTALLDIR="@@INSTALL_DIR@@\MySQL\" DATADIR="@@INSTALL_DIR@@\MySQL\" USERNAME="@@DB_USER@@" PASSWORD="@@DB_PASS@@" (the @@variable@@'s are replace by my installer routine using InstallJammer) Once installed, I use mysqld.exe to install a windows service with a custom service name and defaults file like so: mysqld.exe --install CustomMySQL --defaults-file="@@INSTALL_DIR@@\MySQL\my.ini" This works fine as long as there is not already another instance of MySQL installed. If there is it silently fails to install MySQL. Running the msi installer manually (double-click) shows an error that a previous version is already installed and just aborts. Is there a way to automate installing MySQL as an isolated instance, regardless of whether another version/instance is already installed?

• "Request not supported" in IPCONFIG (WinXP SP3)

  - by pablog

  In a customer PC (Windows XP SP3), suddenly the network went down: the network adapter appears with an error mark. I replaced the network card, but the new one does the same thing. When I enter IPCONFIG, XP shows this error (in standard and safe mode): Internal error occurred Request not supported Unable to query host name If I start the system with a boot cd the PC runs fine, so the problem seems to be in the XP installation. I tried: uninstalling and reinstalling the network card in the Device Manager disabling and reenabling the card netsh int ip reset netsh winsock reset catalog and a couple of "reset" programs (WinsockxpFix.exe, etc) with no luck. Is there any way to fix it without reinstalling XP? TIA, Pablo

• Internet cafe software for linux

  - by pehrs

  I have gotten a request to roll out a total of 8 internet cafe's in a large network. Budget is non-existent as it will all be done for a non-profit. I was planing to use Ubuntu and live-cds to minimize the amount of management required, but I can't seem to find any suitable internet cafe system that is Ubuntu based. The requirements are pretty basic: It needs to keep track of logged in time and log out users when their time it up. No billing will be done, it will just be used to ensure people can share the computers fairly. It should be possible to force logout from a central system. Users will be unskilled, so it has to have a GUI. What (preferably free, considering the shoe-string budget) software would you suggest to manage this?

• RAID-0 problem with a Sony sporting a new HDD

  - by redrock

  Sony Windows 7 PC. Originally had 2 x 300 Gb HDD. One HDD completely pancaked so have replaced with a new 500 Gb HDD. When both drives are connected the 300GB doesn't appear to be recognized as a 300Gb HDD as a separate entity. BIOS sees it but the operating system only sees a total of 465GB of HD space. When both disks are attached under disk management it shows one 465Gb as RAID 0 and the new drive as STxxxxxx 465Gb. My question I guess is what should I see in total HDD space and is this configured correctly as I thought I would see 2 separate drives 1x500Gb and 1x300Gb. My customer insisted that prior to the HDD crash he saw 2 drives both registering as 300Gb (a c: and d: drive).

• bash code in rc.local not excuting after bootup

  - by mrTomahawk

  Does anyone know why a system would not execute the script code within rc.local on bootup? I have a post configuration bash script that I want to run after the initial install of VMware ESX (Red Hat), and for some reason it doesn't seem to execute. I have the setup to log its start of execution and even its progress so that I can see how far it gets in case it fails at some point, but even when I look at that log, I am finding that didn't even started the execution of the script code. I already checked to see that script has execution permissions (755), what else should I be looking at? Here is the first few lines of my code: #!/bin/sh echo >> /tmp/configLog "" echo >> /tmp/configLog "Entering maintenance mode"

• GlusterFS with CIFS, quotas and LDAP

  - by lpfavreau

  Has anyone had experience plugging GlusterFS and Openfiler together or something similar? Here is the motivation: Disk space on multiple server regrouped using GlusterFS Centralized access using LDAP/AD and quota management using Openfiler as the GlusterFS client SMB/CIFS server for easy sharing to multiple users on Mac and Windows I know I can have Gluster installed on Openfiler (rPath Linux) successfully but Openfiler seems to be very picky on what it can use as a shared drive. Mounting the Gluster volume inside an existing share does not seem to allow quotas with the mounted folder free space. If this is not possible, is there any alternative to give the same capabilities?

• WinXP keyboard input repeat rate problem

  - by Victor Sorokin

  I have problem similar to http://superuser.com/questions/33981/problems-with-kvm-switch-and-keyboard-repeat-rate-on-windows-xp: When I press and hold some key it's repeated random number of times, after that repeat stops and I need to release key and press it again to make repeat continue. If there's simultaneous sound playback and repeat is stopped, sound's stuck while I hold key with unpleasant drumming as if there's some audio problem. This issue is reproducible in WinXP Safe Mode. On the same config under Linux there's no issue. My config: List item PS/2 Logitech Keyboard USB Mouse MB M3A/H-HDMI WinXP Pro English SP2 with added Russian layout (WinXP loads via GRUB2) Realtek audio drivers for AC97 Thanks for your suggestions J

• Windows 2008 Server in Amazon EC2 stops responding when SSTP/VPN connection is closed

  - by user38349

  All, I have a single Windows 2008 server running in Amazon's EC2 cloud. It's running a web application that is running fine and is accessible to the outside world. I need 3-5 developers to be able to work on database on the server, and was intending to accomplish this by setting up SSTP/RRAS on the server and letting them VPN in. This has been a bit of an ordeal due to the amount of server roles and messing with certificates that has been needed, but my VPN connection works now (all clients will be Windows 7). My problem is that when I use my VPN connection (from the client side) the server hangs - although not at any any consistent place, sometimes it's when I close the connection, some times when I'm making the connection). The only way that I've found to get it back is to reboot it from the Amazon management console. Thanks for any guidance. Duncan
