  • Is a rubber keyboard suitable for heavy use?

    - by Vilx-
    Every keyboard wears out with time, and mine has some age already. The day it fails is coming closer and closer. So I'm slowly starting to look around for a new one. I use the keyboard for gaming and programming, so it gets some pretty solid use. I also tend to eat by the computer, so there's plenty of... uhh... lifeforms down there. Anyway, I was looking at these rubber keyboards. They come pretty cheap (my local computer shop has one for less than $20) and they seem to have some nice properties. They can be easily cleaned, they're quiet, and can be rolled up when needed (plus no worries about spilled drinks). However I'm wondering what their type-ability is. If I can't write on it at a decent speed, the rest of the features don't matter. Not that I'm a fast typer, but being a professional progammer does give a boost to the skill. I couldn't find any reviews on the net so I'm turning to you. Who has used these keyboards and what was your experience? Perhaps there is something else I haven't though of why such a keyboard would not be a good idea?

  • ATI HDMI Audio disappears in Windows 7 when a TV is connected

    - by jsalonen
    So far I have unsuccessfully googled for HOURS with no luck fixing this very annoying problem. The settings is the following: I have PC running Windows 7 RC (64-bit) Video card is a ATI Radeon 4850 series card (Sapphire HD 4850 512MB to be exact) The video card has HDMI out with built-in audio chip I have an HDMI cable connecting the PC to a TV (Sony Bravia series) The problem is that when I connect the HDMI cable to the TV, the ATI HDMI Sound output device disappears completely from the list of playback devices in Windows. As a workaround I can restore the audio by re-installing the HDMI audio driver. However, when I disconnect the TV the driver disappears again. So basically, every time I want to watch stuff on my TV, I have to reinstall audio driver, which of course is VERY annoying. EDIT: I have figured out that I do not need to re-istall the HDMI audio driver to restore sound; I only need to reboot my computer with the HDMI cable plugged in to restore the audio driver. This suggests that the problem has something to do with information passed from TV to computer, which makes my HDMI Audio driver disappear. Are there any other, more elegant workarounds for this problem? All help is much appreciated!

  • Sync clock on Windows XP machine to external (non-domain, non-workgroup) Windows Server 2008 R2 machine

    - by Eric
    I have two machines and I'd like their clocks to be in sync for various reasons. Machine 1 is an XP machine located in the office. Machine 2 is a VPS hosted by a third party running Windows Server 2008 R2. These machines are not in any kind of workgroup or on a domain together. They are completely separate machines. Machine 2 is currently syncing once a week to time.windows.com. The clock on Machine 2 does seem to wander a bit within that week interval. What I would like to do is have Machine 1 set its clock based on the clock of Machine 2. I have tried configuring w32tm on the XP machine. This is what I used for configuration: w32tm /config /syncfromflags:manual /manualpeerlist:"<ip address of machine 2>" However, whenever I issue the /resync command I get "The computer did not resync because no time data was available". I have made sure to start the windows time service on machine 2, and I have added firewall exceptions for UDP port 123. Is there something I need to configure on Machine 2 (other than just starting the time service) in order to get it to respond? Edit: I have also run w32tm /config /reliable:YES /update on Machine 2. I am still getting "The computer did not resync because no time data was available". Is there something else I'm missing?

  • Best way to 'harden' embedded ext4 file server against unexpected loss of power?

    - by Jeremy Friesner
    Hi all, First, a little background: my company makes an audio streaming device that is a headless, rack-mounted Linux box with a couple of SSDs attached. Each SSD is formatted with ext4. The users can connect to the system using Samba/CIFS to upload new audio files or access existing ones. There is also custom software for streaming out audio over the network. This is all fine. The only problem is that the users are audio people, not computer people, and see the system as a 'black box', not as a computer. Which means that at the end of the day, they aren't going to ssh in to the box and enter "/sbin/shutdown -h"; they are just going to cut power to the rack and leave, and expect things to still work properly the next day. Since ext4 has journalling, journal checksumming, etc, this mostly works. The only time it doesn't work is when someone uploads a new file via Samba and then cuts power to the system before the uploaded data has been fully flushed to the disk. In that case, they come in the next day and find that their new file has been truncated or is missing entirely, and are unhappy. My question is, what is the best way to avoid this problem? Is there a way to get smbd to call "sync" at the end of every upload? (Performance on uploads isn't so important, since they only happen occasionally). Or is there a way to tell ext4 to automatically flush within a few seconds of any change to a file? (Again, performance can be sacrificed for safety here) Should I set a particular write-ordering mode, activate barriers, etc?

  • SQL Server Agent refuses to start

    - by Geo Ego
    I'm having a problem with SQL Server 2005 where the SQL Server Agent suddenly refuses to start. If I attempt to start it through Services, I get the error "SQL Server Agent (MSSQLSERVER) service on Local Computer started and then stopped." In the Application log, I have the following entry: Event Type: Error Event Source: SQLSERVERAGENT Event Category: Service Control Event ID: 103 Date: 5/20/2010 Time: 11:07:07 AM User: N/A Computer: SHAREPOINT Description: SQLServerAgent could not be started (reason: Unable to connect to server 'SHAREPOINT'; SQLServerAgent cannot start). This database has been running fine for four months. It contains a SharePoint configuration database, which two days ago stopped working, throwing me a message that the configuration database cannot be reached. It was then that I realized the SQL Server Agent was not running, and I have been unable to restart it. I have tried running it with both the local system account and the network service account, with the same results. So far, I have tried: Granting the administrators group, network service, and SharePoint SQL Server Agent account public and sysadmin roles on the database. Granting the administrators group, network service, and SharePoint SQL Server Agent account full permissions to the entire MSSQL directory and all files within. I still have no joy.

  • Vista WHS Client stopped resolving local names

    - by andrewcr
    I’m running Windows Home Server PP2 in my home, with 3 client computers: two XP and one Vista. I have a router that provides my local DHCP and the server has a static IP address. The other day the Vista machine hung, and on reboot stopped resolving local names. It will show the green home server client icon in the system tray, but if I attempt to log in to the console, I get a “This computer cannot connect to your home server” message. If I ping the server name from the command line, it does not resolve, and gives a “could not find host” message. Oddly enough, if I browse the network, I can see the server, but double clicking on it fails. The other machines on the local network have no problems seeing the server, and the Vista machine has no problems resolving names from the internet, it just can’t see any local machines. I’m aware that I can work around this by adding entries to my HOSTS file (it does work), but I’d like this to work the way it’s “supposed” to. I’m an experienced computer user and developer, but not a networking whiz. Can anyone tell me how local name resolution is supposed to work in my environment and/or suggest ways to troubleshoot this? Thanks, Andy

  • SSD cache to minimize HDD spin-up time?

    - by sirprize
    short version first: I'm looking for Linux compatible software which is able to transparently cache HDD writes using an SSD. However, I only want to spin up the HDD once or twice a day (to write the cached data to the HDD). The rest of the time, the HDD should not be spinning due to noise concerns. Now the longer version: I have built a completely silent computer running Xubuntu. It has a A10-6700T APU, huge fanless cooler, fanless PSU, SSD. The problem is: it also has (and needs) a noisy HDD and I want to forbid spinning it up during the night. All writes should be cached on the SSD, reads are not needed in the night. Throughout every day, this computer will automatically download about 5 GB of data which will be retained for about a year, giving a total needed disk capacity of slightly less than 2 TB. This data is currently stored on a 3 TB noisy hard disk drive which is spinning day and night. Sometimes, I'll need to access some data from several months ago. However, most times I'll only need data from the last 14 days, which would fit on the SSD. Ideally, I'd like a transparent solution (all data on one filesystem) which caches all writes to the SSD, writing to the HDD only once a day. Reads would be served by the cache if they were still on the SDD, else the HDD would have to spin up. I have tried bcache without much success (using cache_mode=writeback, writeback_running=0, writeback_delay=86400, sequential_cutoff=0, congested_write_threshold_us=0 - anything missing?) and I read about ZFS ZIL/L2ARC but I'm not sure I can achieve my goal with ZFS. Any pointers? If all else fails, I will simply use some scripts to automatically copy files over to the big drive while deleting the oldest files from the SSD.

  • Remote Desktop Network Level Authentication Not Supported

    - by Iszi
    I'm running Windows XP Professional SP3 x86, trying to connect to a system with Windows 7 Ultimate SP1 x64. Recently, I updated the Remote Desktop Connection software on the XP system in hopes of using Network Level Authentication (NLA) for my connections to the Windows 7 box. After the update, I connected to the Windows 7 box over RDP and enabled NLA believing that the updated client should support it. After disconnecting and attempting to reconnect, I'm presented with the following error: The remote computer requires Network Level Authentication, which your computer does not support. For assistance, contact your system administrator or technical support. So, I checked the About page in Remote Desktop Connection to make sure the update had applied. This is what I see. Remote Desktop Connection Shell Version 6.1.7600 Control Version 6.1.7600 © 2007 Microsoft Corporation. All rights reserved. Network Level Authentication not supported. Remote Desktop Protocol 7.0 supported. I thought NLA was supposed to be a part of RDP 7.0 clients. Is there a component I'm missing somewhere?

  • How to start using twill?

    - by brilliant
    How do I start using twill? I have just downloaded it, unpacked it and clicked on the setup .py file in the folder. The black window (terminal) appeared for a moment and vanished. (I do have Python 2.5 installed on my computer - along with SDK from Google App Engine) In the twill documentation section it says: Downloading twill The latest release of twill is twill 0.9, released Thursday, December 27th, 2007; it is available for download at http://darcs.idyll.org/~t/projects/twill-0.9.tar.gz. You can also use Python's easy_install to install or upgrade twill. twill works with Python 2.3 or later. To start using twill, install it and then type twill-sh. At the prompt type: go http://www.slashdot.org/ show showforms showhistory I am not clear from this passage what I am supposed to type (only "twill-sh" or "twill-sh" and all the words under that line) and where (I tried typing it in the command prompt window of my computer - to no avail) Can, anyone, please, help me out here? Thank You in advance.

  • How to force a login for an administrator when using Remote Desktop Connection and fast user switching enabled?

    - by brett rogers
    Scenario: I am at work. I want to remote desktop into my machine at home. Problem is, my 5-year-old daughter is playing games on Starfall.com (or something similar) on her (non-admin) account. When I attempt to connect I see this message: Another user is currently logged on to this computer. If you continue, this user has to disconnect from this computer. Do you want to continue? I click Yes and then see Please wait for 'UserName' to respond This presents my daughter with an Allow/Disallow dialog on whether to let me connect. She clicks Disallow (or No or whatever it says) and then I see 'UserName' has denied your request Question: How can I force my account to log in and disconnect her session? Additional Info: My account is an administrator account. My daughter's account is a non-administrator account. Home machine is Windows 7 Pro with fast user switching enabled. Turning off fast user switching is not an option (Kyle pointed out in his answer that turning it off would allow the admin to force another user off). I would keep fast user switching's ability to change accounts without closing the previous account's session over being able to force myself to connect.

  • Ubuntu 13.04 to 13.10: Filesystem check or mount failed [migrated]

    - by SamHuckaby
    I attempted to upgrade from Ubuntu 13.04 to 13.10 today, and mid upgrade the system started flaking out, and eventually locked up entirely. I was forced to restart the computer, and am now unable to get the computer to boot up at all. When I boot currently, it takes me to the GRUB menu, and I can choose to boot normally, or boot in an older version. I have tried several things, which I list below, but no matter what, when I try to finish booting into Ubuntu, I receive the following error: Filesystem check or mount failed. A maintenance shell will now be started. CONTROL-D will terminate this shell and continue booting after re-trying filesystems. Any further errors will be ignored root@ubuntu-computername:~# I have fun fsck -f and everything appears correct, no errors are reported. and it passes all 5 checks. If I run fdisk -l then I get the following information: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes Disk identifier: 0x00010824 Device Boot Start End Blocks Id System /dev/sda1 * 2048 608456703 304227328 83 Linux /dev/sda2 608458750 625141759 8341505 5 Extended Partition 2 does not start on physical sector boundary. /dev/sda5 608458752 625141759 8341504 82 Linux swap / Solaris Disk /dev/sdb: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0fb4b7e8 Device Boot Start End Blocks Id System /dev/sdb1 8192 625139711 312565760 7 HPFS/NTFS/exFAT I am considering just installing a new OS on the other disk, that currently has nothing on it, and then just attempting to scrape my data off the old disk (thankfully I didn't encrypt the files).

  • Is it possible to stop the "Beep" device on all computers in a Windows network?

    - by sharptooth
    On Windows the default behavior it to make an annoying "beep" sound every time Windows things something notable happened. The result is that when someone send a company-wide email via the MS Exchange all computers around my cubicle beep one by one. This is annoying and makes no sense. Luckily beeping can be shut off. Someone has to: open the "Device Manager", select "View - Show hidden devices", find the "Beep" device in "Non-Pug and Play Devices" node, open its properties, go to the "Driver" tab, set "startup type" to "Disabled" and click "Stop". The "Beep" device will stop and no longer produce the useless sound. This solution however requires tracking every computer and then talking to its user which is not very convenient. Device Manager doesn't allow stopping a device on another computer. I'm looking for a solution that can be deployed by the administrators team. We have a domain and the administrators even install the programs company-wide automatically. Are there any means to stop the "Beep" device an all computers in the Windows network with some remote-administration features automatically?

  • Dual boot windows 8 pro and windows 7 on XPS 8500 Special Edition

    - by Jesse
    I am trying to install a dual boot with windows 7 premium and windows 8 Pro on an XPS 8500 special edition. I created a new primary partition on my C: drive, inserted the windows 8 install disk, and rebooted my computer from DVD. I select custom install and the dialog box saying "Where do you want to install windows at?" pops up but none of my drives are listed. Please help me determine what is going on. I don't understand why none of my drives are showing up on this menu. Not even the original drive. When I go to load driver and click on the partition I created it tells me "No signed device drivers were found. Make sure the installation media contains the correct drivers, and then click OK." resolved above issue by running setup from the source folder on the install disk instead of booting from DVD. Was able to locate my new partition and start install. It completes the first step of "Copying windows files" just fine but then on the next step "Getting files ready for installation" my computer restarts and attempts to load windows 8 but keeps telling me my pc needs to restart. This keeps going on in an infinite boot loop. Please help, this has been a nightmare!

  • How does the "Steam" platform work? Is it DRM? Can I trust "Steam"-powered software? [closed]

    - by Chris W. Rea
    So – I just bought the new game Supreme Commander 2. This question is not about the game, but about the online software installation platform that it seems to require. I haven't bought a game in a long time, and I'm puzzled: Apparently, SC2 is a "Steam"-powered game. When I went to install the game, it asked me to either create a new Steam account, or log in with an existing account. I clicked "Cancel" because I don't plan to play online and I don't want anything unnecessary installed on my computer, since I only plan to play single player! However, after clicking "Cancel", the installer asked for my confirmation that I indeed wanted to cancel installation of the game! I thought I was just canceling the "online" portions! So I really want to know: How do "Steam" powered games work? Is this essentially a form of DRM (Digital Rights Management)? Can I trust this software platform? Has anybody done any independent verification on how this platform works? (I'm very leery of any DRM after the Sony BMG CD copy protection scandal. Thank goodness for Mark Russinovich.) Does the "Steam" platform install anything particularly nasty or unwanted on my computer? High-rep users: Please vote to reopen this question. It is not about the game, but about the software update platform / updater / DRM. Imagine if the software in question were a productivity application. The issues remain the same.

  • Very slow connection to xserve via afp or smb

    - by Mhoffman13
    Help. File transfer and connection speed to our Xserve are painfully slow from newly purchased iMacs. The Xserve is only used as a file server, its running 10.4.11. The problem seems to be only happening on brand new iMacs running 10.6.3. When connected either over afp or smb copying files is many times slower than usual. Other machines on the network running either 10.4 or 10.5 have a normal connection speed. To try to rule out OS incompatibility I connected the new iMac running 10.6 to another computer running 10.4 over the network. The file transfer speed was fast as normal. So it seems the problems lies with the X serve (maybe). The afp logs either access or error don't show anything unusual. One thing that did look different was when the imac was connected to the Xserve the user had its id listed as its IP address. The other machines connected, had the id of broadcasthost. I also noticed that when connected from the new iMac I can only see one of the mirrors. When any other computer connects both mirrors are shown. Tried a restart of the Xserve but the problem persists. Thanks in advance for any advice

  • Where do I define a group policy that will set a users desktop background color to green the first time they log in?

    - by Tyler
    Servers: W2k8 R2 x64 Desktops: Win7 Pro x64 Our current group policy uses a custom ADM file to define certain properties of the desktop (Background Image (centered), Background Color is green (00 74 00)). This policy works for us, but the down-side is that policies defined in our custom ADM are only applied after a GPUpdate /Force is applied. We would like these desktop theme settings to be applied the first time the user logs onto the computer. I've been working on a new policy that forces the computer to wait for the network when the user logs on to handle folder redirection. The reason for writing the new policy was to resolve the issue that a user needs to run GPupdate /Force the first time they log in, so it doesn't make sense for me to implement the new policy if there is still something that requires GPUpdate /Force to get the user in the state that we want them. I've moved the setting for background image out into Admin Templates- Desktop- Desktop- "Desktop Wallpaper" so this is now being set properly when the user first logs in. Now I'm left with a black background until I force a group policy update. I have tried to play around with setting a default "Theme" and had limited success; this was not reliable enough to call a solution. I suppose I could set the background color with a script? Any thoughts? It feels like I'm missing something obvious, or that this should be much easier than it is.

  • Access Windows Boot Manager selector when timeout is set to 0?

    - by Kyle Cronin
    I've installed Wubi onto a Windows Vista computer. I've also set the boot timeout to 0: bcdedit /timeout 0 However, now I can't figure out how to get the menu to come up at all! I read on the internets that I had to hold F8 or space when starting up, but they doesn't seem to do anything. Is there a different key or setting I've overlooked? The computer itself is a Dell that's a few months old. The keyboard is USB, but I don't think that's the problem as I can get into the BIOS just fine. Maybe I'm doing it wrong? Am I supposed to hold the keys or rapidly tap them (I've tried both)? If it helps, here's the output from bcdedit: C:\Windows\system32>bcdedit Windows Boot Manager -------------------- identifier {bootmgr} device partition=C: description Windows Boot Manager locale en-US inherit {globalsettings} default {current} resumeobject {5460d9d2-d391-11dc-9d9f-aba67a8797c5} displayorder {current} {e2484fe7-5e97-11de-84d4-0024e8074422} toolsdisplayorder {memdiag} timeout 0 resume No Windows Boot Loader ------------------- identifier {current} device partition=C: path \Windows\system32\winload.exe description Windows Vista locale en-US inherit {bootloadersettings} recoverysequence {572bcd55-ffa7-11d9-aae0-0007e994107d} recoveryenabled Yes osdevice partition=C: systemroot \Windows resumeobject {5460d9d2-d391-11dc-9d9f-aba67a8797c5} nx OptIn Real-mode Boot Sector --------------------- identifier {e2484fe7-5e97-11de-84d4-0024e8074422} device partition=C: path \ubuntu\winboot\wubildr.mbr description Ubuntu

  • Mac Grey/White Screen of Death

    - by cust0s
    The other night I updated my iTunes to the latest version (through Software Update) when I came to turn on my computer I was greeted with the dreaded white screen of death. I use an early 2008 iMac 24". I've tried the basic things, unplugging/turning off accessories, trying to boot from the install disk, reseting pram, etc, etc. Still no luck and no change what-so-ever. All I've been able to ascertain that my keyboard still works (by ejecting). I should point out that I did recently replace my Hard drive with a Western Digital Black 500GB (though the computer is well out of warrenty) and I'm a little concerned that the problem could be the screen. Update (18/05/10): I've been told that I could be getting the White/Grey screen of death because the optical flex cable is damaged (aparently this is common). Apparently the Optical Drive is part of the POST sequence, and an inability to read the drive can result in failure for the system to move on to other bootable volumes. More info here. I will disable the optical drive and see if that works.

  • Hyper-V Virtual Machine won't respond over network

    - by Brad Gignac
    Recently, one of our Hyper-V virtual machines has periodically stopped responding over the network. It seems to be happening every few days, and it occasionally happens up to several times a day. I am by no means a sysadmin, so any direction you guys could provide would be very welcome. I've included everything I know to include below. If you need any additional information, I'll be glad to include it. I can connect through the Hyper-V console. I can't connect to network shares, IIS web apps, using RDP, or using ping. Memory usage seems to be normal (3 of 4 GB) Processor usage seems low. We don't know the exact time the server goes down, but the following error appears consistently around the time it goes down: Error 5719, NETLOGON This computer was not able to set up as secure session with a domain controller in domain *** due to the following: There are currently no logon servers available to service the logon request. This may lead to authentication problems. Make sure that this computer is connected to the network. If this problem persists, please contact your domain administrator.

  • HAProxy "503 Service Unavailable" for webserver running on a KVM virtual machine

    - by Menda
    I'm setting up a server with KVM (IP 192.168.0.100) and I have created inside of it one virtual machine using network bridging at 192.168.0.194. This virtual machine has an nginx instance running, which I can access from the server or from any computer computer in the internal network just typing in the browser http://192.168.0.194. However, I try configure HAProxy in the same server that hosts KVM and looking the status page of HAProxy it always shows the virtual machine as "DOWN". If I try from the server http://localhost, it should be the same than if I go to http://192.168.0.194. My goal is to build a reverse proxy, but I tried this little example and won't work. What am I doing bad?

  • Windows XP error message: "Windows cannot find 'explorer.exe'"

    - by Meysam
    In Windows XP I can open "My Computer" and see all the hard drives. I can also see the explorer.exe process running among other processes in Task Manager. But after opening "My Computer", when I double click on one of the drives to open it, I get the following error message: Windows cannot find 'explorer.exe'. Make sure you typed the name correctly, and then try again. To search for a file, click the start button, and then click search. Although I could detect and remove several suspicious files using Malwarebytes & Microsoft Security Essentials, the problem still remains. The interesting point is that if I right click on one folder and select Open or Explore from the menu bar, I can open the folder! but if I double click on the folder, it does not open and I get the above error message. How can I fix this problem? Any advice would be appreciated! Update: I formatted the C: drive (NTFS), a deep format, and installed a fresh Windows XP on it. I am not getting this error when I double click on C drive icon anymore. But the same error appears when I double click on other drive names. Maybe I should format them too!

  • Unable to connect to cable modem when connected to VPN

    - by Spuas
    the scenario is as follows: First I have a cable modem which gives the internet connection. The network is 192.168.0.0/24 and its IP is 192.168.0.1 Second line, I have a router connected to the cable modem. Its "outside" IP is 192.168.0.12. This router creates network 192.168.123.0/24 and its IP there is 192.168.123.254. My computer is wired to the router with IP 192.168.123.126. At this point I am able to access both devices web interfaces by their IPs on a browser (192.168.123.254 for the router and 192.168.0.1 for the cable modem). The problem I have is when I connect to a VPN from the computer. Then I am connected to a second network 10.0.0.0/24 and I get IP 10.0.0.200 (along with 192.168.123.126). I can connect to the router but then I loose connectivity to the cable modem: I cannot acces it through the browser, neither making a ping to it or a tracert. I have tried to add a new route to the windows routes by typing route ADD 192.168.0.1 MASK 255.255.255.0 192.168.123.254 but I cannot access it anyway... Am I missing something on the route adding? Which is the propper way of doing this? Thanks

  • Unix Permissions: Enable access to files no matter the user?

    - by TK Kocheran
    I've been using Linux for a long time and I still am completely in the dark about how file permissions really work. With that in mind, does anyone have any books or thorough guides I could read to really understand things completely? I've done my fair share of sysadminning, so I know the easy stuff like making directories readable and writable, making files executable, and changing the owner of a file, but on sharing files across users, I'm lost. Here's my main problem. I have a number of machines across which I intend to synchronize my music library. I've been using Unison for a while now and it's a great choice as I can easily run it over SSH on my local network which I just set up. Win-win. Up until this point, I've been synchronizing computers using a 2TB external hard drive. (computer 1 unisons to HD, computer 2 unisons to HD, etc.) This is tedious at best, especially since I encrypted the drive, making it a huge hassle to hook it up to all of my machines and sync it. Anyway, the drive is running ext4 (in TrueCrypt), so it maintains all Unix filesystem info like owners and groups. I just set up a new machine and just Unison'd it to get the music on it, and I realized that now, all of my permissions are fubar. I had to run Unison as root since that was the only way I could get the files to come off of the external drive. Apparently, since I'm using a different user name on this machine than my usual "rfkrocktk" across all machines, this essentially throws a huge wrench in the gears. Here's my use case. This laptop has two effective users, "leandra" and "rfkrocktk". I want to share music between these two users, so I symlinked /home/rfkrocktk/Music to point to /home/leandra/Music. How do I (a) allow both users access to read/write/delete files in this folder, and (b) keep everything nicely in sync without messing up file ownership?

  • Logmein does not work at home?

    - by Littlet-ENG
    I've been using logmein successfully for may situations and have had very good success. Our company has an Log me in Pro account. I have used this to share my desktop with customers. At work, I have had no problem with my laptop. At home, one program (solid-works) that I need to share with my customers, will not display the active screen. I spent 45 min on the phone with both the software for the cad system and logmein support with not help. I need help in narrowing down what the problem is on my computer. The support guys at Solid-works got another remote software to work, so its not the program. I can get the logmein to work at the office so its not the settings of the logmein pro account. The LMI people say its a setting on my computer.? -internet is fast enough at home -can't narrow down the problem -changed graphical settings and that didn't work. Any Suggestions?

  • Choose identity from ssh-agent by file name

    - by leoluk
    Problem: I have some 20-30 ssh-agent identities. Most servers refuse authentication with Too many failed authentications, as SSH usually won't let me try 20 different keys to log in. At the moment, I am specifying the identity file for every host manually, using the IdentityFile and the IdentitiesOnly directive, so that SSH will only try one key file, which works. Unfortunately, this stops working as soon as the original keys aren't available anymore. ssh-add -l shows me the correct paths for every key file, and they match with the paths in .ssh/config, but it doesn't work. Apparently, SSH selects the indentity by public key signature and not by file name, which means that the original files have to be available so that SSH can extract the public key. There are two problems with this: it stops working as soon as I unplug the flash drive holding the keys it renders agent forwarding useless as the key files aren't available on the remote host Of course, I could extract the public keys from my identity files and store them on my computer, and on every remote computer I usually log into. This doesn't looks like a desirable solution, though. What I need is a possibility to select an identity from ssh-agent by file name, so that I can easily select the right key using .ssh/config or by passing -i /path/to/original/key, even on a remote host I SSH'd into. It would be even better if I could "nickname" the keys so that I don't even have to specify the full path.
