  • Enter network credentials as part of batch script

    - by Michael
    WinXP: I have several system services that are needed to run some machinery in my lab. The machine these services are running uses a lab login that has administrator rights. Our IS department, unfortunately, has it set up where at some point during the night the login "loses" the privilege level to start/stop these services. The account stays logged in, but the software controlling my hardware becomes unresponsive. In order to get things back up and running, I have to stop the system services and restart them. Because of the security settings, however, I have to re-enter the user password to start the service (even though the user was never logged out). That, I get the "This service cannot be started due to a logon failure" and I have to enter the password. What would be ideal is to have a batch script run before anyone gets into work that stops all of the necessary services, enters the user credentials when prompted, and then restarts them so that everything is ready for first shift to run. I assumed that using the Task Scheduler in Windows would work as it allows you to run batch files with a user's name and password, but this didn't seem to do the trick. With this setup I would arrive to find that all the services are stopped but not started again. (Presumably because the authentication failed.) The batch file is about as simple as it gets, all I have is: net stop "Service1" net stop "Serivce2" etc., then restart in reverse order based on dependency: net start "Service2" net start "Serivce1" What would it take to accomplish what I'm trying to do and restart the services?

  • IBM BladeCenter S: Disk Configuration

    - by gravyface
    Have just the one storage bay right now (SAS 15K 600GB x 6) and have configured one storage pool in RAID 10 with 4 disks (and two global spares). For each blade, I've created a volume and mapped accordingly: Blade #1 400 GB Blade #2 200 GB Blade #3 100 GB Blade #4 100 GB When I boot up Blade 1 and enter into the UEFI Setup (F1) followed by the Adapters and UEFI Drivers LSI Logic Fusion MPT SAS Driver Utility, I see 4 disks: two are the on-board 73GB drives, the other two are 200GB each and assume I'm being presented with two logical disks from the volume I created and mapped to this blade. I was a bit surprised by this: I figured I would've been presented with one logical drive per volume, not two. I'm assuming I can just configure whatever RAID level I wish that supports two disks, but not really sure what the benefits/trade-offs here. Should I go with RAID 10 on top of RAID 10? RAID 0? Software RAID 0/1/10? Does it even matter? If this is "normal" to see two disks, then I'm going to likely just do some benchmarking and see if it makes a difference changing the RAID levels (my guess is no); if this is not normal, well, please let me know. :)

  • Handling emails on a web server - Making sure the FQDN is set correctly based on the website sending the email

    - by webnoob
    I have a Windows 2008 Web Edition server hosting multiple websites using IIS 7.5. At the moment, all the emails are sent via the IIS6 SMTP service. The FQDN of the SMTP service is set to the computer name at the moment which isn't correct as it doesn't resolve to a valid DNS entry and is not RFC compliant. Some questions: Is there any way I can change the FQDN of the SMTP service based on the site sending the email? Would it be Ok to just setup mailserver.mydomain.com and use that as the FQDN for all the sites on multiple domains. Should I be using some other mail server software to handle this better? The reason I am asking is lots of emails are hitting spam folders because the settings are incorrect. I have access to the code that is running the websites so if something needs to be done there then that shouldn't be a problem. The sites are written using ASP.NET 2.0. EDIT: I have just found an option to create an SMTP virtual service. Would this be the way forward? Create a virtual server for each site? Thanks.

  • RAID degraded on Ubuntu server

    - by reano
    We're having a very weird issue at work. Our Ubuntu server has 6 drives, set up with RAID1 as follows: /dev/md0, consisting of: /dev/sda1 /dev/sdb1 /dev/md1, consisting of: /dev/sda2 /dev/sdb2 /dev/md2, consisting of: /dev/sda3 /dev/sdb3 /dev/md3, consisting of: /dev/sdc1 /dev/sdd1 /dev/md4, consisting of: /dev/sde1 /dev/sdf1 As you can see, md0, md1 and md2 all use the same 2 drives (split into 3 partitions). I also have to note that this is done via ubuntu software raid, not hardware raid. Today, the /md0 RAID1 array shows as degraded - it is missing the /dev/sdb1 drive. But since /dev/sdb1 is only a partition (and /dev/sdb2 and /dev/sdb3 are working fine), it's obviously not the drive that's gone AWOL, it seems the partition itself is missing. How is that even possible? And what could we do to fix it? My output of cat /proc/mdstat: Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md1 : active raid1 sda2[0] sdb2[1] 24006528 blocks super 1.2 [2/2] [UU] md2 : active raid1 sda3[0] sdb3[1] 1441268544 blocks super 1.2 [2/2] [UU] md0 : active raid1 sda1[0] 1464710976 blocks super 1.2 [2/1] [U_] md3 : active raid1 sdd1[1] sdc1[0] 2930133824 blocks super 1.2 [2/2] [UU] md4 : active raid1 sdf2[1] sde2[0] 2929939264 blocks super 1.2 [2/2] [UU] unused devices: <none> FYI: I tried the following: mdadm /dev/md0 --add /dev/sdb1 But got this error: mdadm: add new device failed for /dev/sdb1 as 2: Invalid argument Output of mdadm --detail /dev/md0 is: /dev/md0: Version : 1.2 Creation Time : Sat Dec 29 17:09:45 2012 Raid Level : raid1 Array Size : 1464710976 (1396.86 GiB 1499.86 GB) Used Dev Size : 1464710976 (1396.86 GiB 1499.86 GB) Raid Devices : 2 Total Devices : 1 Persistence : Superblock is persistent Update Time : Thu Nov 7 15:55:07 2013 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 Name : lia:0 (local to host lia) UUID : eb302d19:ff70c7bf:401d63af:ed042d59 Events : 26216 Number Major Minor RaidDevice State 0 8 1 0 active sync /dev/sda1 1 0 0 1 removed

  • centos install / partitioning

    - by ServerSideX
    I'm using NOC-PS to remotely install Centos 6.2 via KVM / IPMI. I'm going to install cPanel as well and they recommend this layout /boot (99MB) swap (2x server RAM) / (remainder) In the o/s install profile within NOC-PS software, it shows as this: part /boot --fstype ext2 --size 250 part pv.01 --size 1 --grow volgroup vg pv.01 logvol / --vgname=vg --size=1 --grow --fstype ext4 --fsoptions=discard,noatime --name=root logvol /tmp --vgname=vg --size=1024 --fstype ext4 --fsoptions=discard,noatime --name=tmp logvol swap --vgname=vg --recommended --name=swap By the time the default partition setup was done installing Centos, I get this [root@server005 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg-root 532G 907M 504G 1% / tmpfs 7.8G 0 7.8G 0% /dev/shm /dev/sda1 243M 28M 202M 13% /boot /dev/mapper/vg-tmp 1008M 34M 924M 4% /tmp [root@server005 ~]# cat /etc/fstab # # /etc/fstab # Created by anaconda on Fri Dec 7 18:47:24 2012 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/vg-root / ext4 discard,noatime 1 1 UUID=58b31aaf-5072-4fb1-a858-33bc316fa793 /boot ext2 defaults 1 2 /dev/mapper/vg-tmp /tmp ext4 discard,noatime 1 2 /dev/mapper/vg-swap swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 My question is, how should the NOC-PS install profile look like to get the recommended cPanel partitioning? The server has 16GB RAM, dual 600GB SAS drives and will be used for cPanel shared hosting.

  • Value of Itanium or Sparc over x86_64 for Oracle Deployment

    - by Antitribu
    We are looking at a new environment to run our Oracle Database running on SUSE (potentially migrating to RedHat). Our database is approximately 100GB and performs adequately on our current hardware (x86_64) with approximately 6GB of ram allocated to it. We are growing quickly however and will require more performance shortly. Given the cost of Oracle licenses we would like to maximize the value from each license by choosing the most appropriate CPU to run the software on. The questions are: Are there substantial benefits to looking at Itanium or Sparc hardware, are there any drawbacks? Is there a point where one starts to scale out better? What are the long term support options for Itanium? Given the dominance of x86 would it be safer long term to stick with x86? On average what would be the performance benefit of implementing an Oracle database on Itanium or Sparc over x86_64? Is this an issue at all or will other factors (IO/RAM) cap out first? If anyone can point me towards some solid documentation on comparisons between the platforms that provides good case analysis of when to choose which I'm more than happy to accept that as an answer. Edit:- Added Sparc as an Option as it was previously not considered however with the recent Oracle Sun aquisition seems very relevant.

  • why would resetting the Netgear N300 router fix my Win 7 laptop's slow wifi?

    - by rjnagle
    In the past day the wifi download speeds of my Win 7 HP 64 bit laptop have slowed considerably. I am trying to troubleshoot the problem and to figure out whether it's hardware related (i.e., is the Intel(R) Centrino(R) Wireless-N 2230 the problem?) or router related. I have a Netgear N300 router connected to my modem. I'm using Speedtest to measure my speed. First, during my problem state, my ipad can download and upload at normal speeds. It's only my Win 7 laptop which is having problems. Because my ipad downloads at normal speeds, that would tell me that the problem is specific to the laptop (either HW or SW). But when I restarted my Netgear router, the laptop wifi problems disappeared. That just doesn't make sense. If we know that one device can connect properly to the router, why would a laptop have problems? What are some possible reasons why this might happen? Also, during my problem state, I noticed that on my laptop upload speeds were faster than my download speeds. Anybody have a guess about what might cause upload speeds on one device to be faster than another? Is there any actions i could take (or options to enable) so this problem won't occur. (I initially thought my problem might be software related or memory related -- Norton AV or browser plugins. But even after I disabled everything and made sure memory footprint was minimal, the slowdown was still occurring -- and it solved itself altogether when the router was reset).

  • Why is there no /usr/bin/ in windows? Would it be dangerous to the entire Program Files to the path?

    - by dotancohen
    I am a Linux user spending some time in Windows and I'm trying to understand some of the Windows paradigms instead of fighting them. I notice that each program installed in the traditional manner (i.e. via orgasmic installers: Yes, Yes, Yes, Finish) adds the executables to C:/Program Files/foo/bar.exe and then adds a shortcut to the Desktop / Start Menu containing the entire path. However, there is no common directory with links to the software, i.e. C:/bin/bar.exe which would link to C:/Program Files/foo/bar.exe. Therefore, after installing an application the only way to use the application is via the clicky-clicky menus or by navigating to the executable in the filesystem. One cannot simply Win-R to open the run dialogue and then type bar or bar.exe as is possible with notepad or mspaint. I realize that Windows 8 improves on this with the otherwise horrendous Start Screen which does support typing the name of the app, but again this depends on the app having registered itself for such. Would I be doing any harm by adding C:/Program Files recursively to the Windows path? I do realize that there will be name collisions (i.e. uninstall.exe) but could there be other issues?

  • Dual hard drive Windows 7 system, modified the registry to get programs to install on second drive, now IE doesn't work

    - by paul
    I have a dual hard drive Windows 7 system, Windows is installed on an SSD (C:) and I modified the registry to try to force programs to install on second HDD drive (another letter). The registry edits are pretty simple, just a few keys in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion to change the drive letter. For the most part the system is very fast and works great, but IE doesn't work anymore. With IE10, it opens for a flash with a white window then closes. I tried installed IE11 which opens a white window for a few seconds, doesn't respond, then crashes. I've tried all the solutions I could find. This includes resetting the IE settings, "uninstalling" and re-installing IE, which is just turning it on and off in "Turn Windows Features on or off", copying the Program Files\Internet Explorer files onto both/either drives, changing the registry keys back to use C:, lots of rebooting, and safe mode. Nothing has worked. I don't see errors in the event viewer, but I might not know what to look for. Any ideas on how to get IE running? I don't need IE for daily browsing, I just need it for cross-browser testing on sites I build and on the rare occasion a page only works in IE. I don't really want to use a virtual machine, but would be ok with something standalone like tredosoft's, but I'm not aware of something like that for current versions of IE.

  • Is there any way to tweak / rotate mouse orientation? Any applications? Registry edits?

    - by calbar
    I've got a very frustrating issue with my new Logitech Marathon Mouse M705. It is absolutely perfect for what I need, with the exception that it tracks on an angle for some reason. What I mean is when you slide the cursor to the left, it trends upward - when you slide to the right, it trends down. Moving the cursor along a flat horizontal line is no longer a natural motion - you need to fight what I suspect is a mechanical error of some kind. Unfortunately, I've already exchanged this mouse once and tested both on different Windows 7 and Mac OS X machines - the problem continues to occur. Is there a software solution for me? I'm incredibly surprised there is no simple way to adjust the orientation... how can every mouse manufacturer possibly adjust their hardware to track to everyone's tastes? What about those who need to flip orientation a full 90 or 180 degrees? I only need to adjust mine a few degrees, but I'm sure that need has arisen as well. Anyway, I'm running the latest SetPoint drivers (6.00) on Windows 7 and there are no orientation options available. I've checked out uberOptions and the M705 isn't supported yet (with the last version update over 6 months ago). MAF Mouse instructions are a very strange series of mouse clicks to activate. This app also seems a little overkill and costs $$ (which I'm willing to pay as a last resort). Is there no universal registry value for mouse orientation? How about for SetPoint drivers specifically? I've done a simple search in regedit without any luck. An XML file somewhere? Anything?

  • Win 7 Media Center - TV - No audio on HD channels

    - by Chuzein Part II
    I wonder if you can help. I have recently purchased a PCTV Nanostick DVD-T2 290e I am running Windows 7 Home Premium 64bit and I use Windows media center for almost everything. I run a media center machine in my lounge through my Sony AV Amp onto my HD TV. I bought the Nanostick to watch ‘Freeview HD’ programmes when watching the TV through the Media Center – I also have a Sony Freeview Plus system that the Mrs uses. I installed the Nanostick with relatively no issues and as described by many user reviews Media Center picked up the new USB tuner and scanned all the new channels and I was presented with all the HD channels. The issue I have is that there is no audio sound from the HD channels but perfect video. SD works fine. The software that comes with the Nanostick works fine – both sound and vision are perfect for the HD channels. As mentioned, I run my Media Centre lots. I have an extensive DVD and BD collection stored on a server and DVD and BD all play perfectly through Arcsoft Total Media Theatre 5 – with no issues on either SD or HD. My sound card is built into my motherboard and that sends the audio signal to my gfx card and that in turn passes it through to my Sony AV Amp that decodes the audio to be heard on my 5.1 set up. Does anyone have any ideas. I have searched lots on the net and I cant find anyone else with the same issue. I am aware of codecs etc but I don’t really understand it. It also puzzles me that when I read the user/buyer reviews for this product so many people tell the story of faultless installations on the same kind of set up as me.

  • Does migrating 2 domain controllers between 2 datacentre requires both virtual machines to be shut down at the same time?

    - by Imagineer
    I was attempting to migrate 2 virtual machines that are domain controllers between 2 datacentres running ESX 3.5 and ESX 4.1. I was advised to shut down both domain controller at the same time during the migration process. This is to avoid USN Rollback and other replication issues. The following are the steps that I was planning to perform: 1. Shutdown both DC. 2. Copy both VMs files across to new datacentre using Veeam FastSCP (connection to both vCentre through IP address instead of hostname) 3. Power them up at new datacentre. 4. Configure Network interface/DNS/DHCP for both DCs in new datacentre I have tried to use Veeam FastSCP rather than VMware Standalone Converter is because its copying rather than converting. Someone also suggested that I use backup and restore app like Veeam backup and replication software. Sounds like a simple job, but after shutting down both DCs, the transfer rate using FastSCP is so slow registering only 1KB/s as oppose to the normal 1MB/s (or more). When that attempt to transfer failed, I tried to cold clone both DCs resulted in the both ESX hosts get disconnected. I have tried troubleshooting by referring to this - VMware KB - Diagnosing an ESX Server that is Disconnected or Not Responding in VirtualCenter It seems that the DNS being down is the caused of all unusual occurrence. The moment I powered up the DCs via VMware console command, the ESX host were able to connect to the vCentre again. How can I avoid such a pitfall again? Am I doing it correctly? Any help would be greatly appreciated! Thank you.

  • iTunes Home Sharing only works one way between 2 Windows XP PC's on the same LAN

    - by scunliffe
    Both PC's have the latest iTunes installed. PC (A) can "see" that there is a shared library "B library" but attempts to connect to it return this error message: The shared library "{Username}'s Library" is not responding (-3259) Check that any firewall software running on either the shared computer or this computer has been set to allow communication on port 3689. however the reverse works fine. e.g. PC (B) can "see" shared library "A library" and can access all content. Notes: Both PC's have Home Sharing enabled (turned off/on several times to verify). Both PC's have Windows Firewall turned on, but in the exceptions tab, iTunes is allowed, and Port 3689 is also added as a firewall exception (just in case) Both iTunes accounts have been "authorized" on both PC's Both PC's connect via LAN via D-Link DIR-615 router. In the advanced application rules, iTunes has also been added to allow traffic on port 3689 un-hindered. Is there any other magical setting/configuration option that I should be aware of and set in order to get this to work? I could care less about sharing apps etc. I just want the music sharing to work. Update: Solved! It turns out on PC (B) there were multiple accounts set up. 1 of the accounts had the checkbox checked under the Windows firewall "On" option which states "No exceptions" thus even though it was added to the exception list on the main user account, this other account was blocking access.

  • Power Outage Interrupted Upgrade from Windows Vista Ultimate to 7 Ultimate, Reverted to Vista, Now Vista is failing... What Next?

    - by tednewk
    I was in the midst of what seemed to be a successful upgrade from Vista Ultimate to 7 Ultimate when there was a brief blackout. The upgrade failed and Windows reverted back to Vista. Now Vista is very slow to boot, has problems waking back-up from inactivity and quickly loses it's wireless connection. The wake-up problem manifests itself as the mouse is clearly shown on a black screen but I have no access to the Desktop or Taskbar or Explorer. Even Alt-Ctrl-Delete doesn't seem to work. No task menu, no reboot. Hitting the reset button reboots the machine with the usual Black Screen warnings offering Safe Mode. I tried to do a system restore to a point before the upgrade. That didn't seem to work. My guess is that my system is a mutant with parts of Vista and parts of 7 crashing each other. I would like avoid a clean install if at all possible to avoid reinstalling other software. What should I try now? My thoughts are: My a system back-up to lock the computer in place Trying a second 7 upgrade If that appears to be working make another back-up If not reload back-up and try a repairing Vista from DVD. If that appears to work make another back-up, let system stablize about a week then try 7 install again If that doesn't work are there any other options to try before settling for a clean install? Another complication, I am doing this by "remote control". I'm traveling with my job and I'll be talking my son through it over the phone. (Kind of like the landing the 747 cliche from all the 70's adventure shows!) So is there a way of simplifying the steps? Thanks Ted

  • Shoretel Upgrade Path

    - by Brian
    I currently have a Shoretel Server running Server 2003 x32 as a virtual machine paired with a ShoreGear 90 switch and another unused switch of the same model being reserved for manual failover. I am getting the software mailed to me from my partner, but with limited support since the server is in a relatively remote area. I am tempted to upgrade the OS at the same time as performing the upgrade, but want to know if there are any horror stories or advice I should know about before diving in. I'm upgrading from Shoretel 9.2 Build. I will be upgrading first to version 10.1 then finally to 11.1. The system has been bullet proof since it was installed and we are upgrading mainly to get a client that is a little more modern. My question boils down to: Should I even bother with an OS upgrade or even possibly a fresh install of Windows with an install of Shoretel 11.1 and just transfer the configuration? Should I just stay with Server 2003 since it is supported in my target version of Shoretel and the upgrade will be more than enough to keep me busy as a novice?

  • How to set an executable white list?

    - by izabera
    Under Linux, is it possible to set a white-list of executables for a certain group of users? I need them to be unable to use, for example, make, gcc and executables on removable disks. How can this be done? Edit, let me explain better. I'm dealing with a high school IT system, young geeks that (during the lessons) want to play, surf the net, damage those computer however they can. The major step to achieve this goal was to remove the system they're familiar with and install Ubuntu in all the computers. This actually works quite well, but recent events proved that this is not enough. I want to allow them to execute certain safe programs, like Open Office, and to deny any other program, whether it is preinstalled software, something they carry in usb drives, a downloaded program or a script they program on site. It's possible to remove the 'x' permission on any file on the pc, but of course it would be impractical. Furthermore, they would be able to run anything they download. I thought the best solution would be to make a white-list of safe programs and to deny anything else, but I don't really know how to do it. Any idea is helpful.

  • Recommended Smartphone for Reading PDFs [closed]

    - by mika
    This is as much a software than a hardware question. I use a lot of public transport and perhaps the best way to spend your time there is to read while listening to music. Currently I use Nokia E90 and Adobe Reader LE 2.5 (full version). I was wondering if there are any better alternatives? Requirements: at least 640px wide screen, preferably 800px physical size of the LCD display matters, it should be large, but the phone itself should be as small as possible. This favors touchscreen models PDF reader should be of high quality. It should render most PDFs correctly. Other important features include: full screen mode, keyboard controls for Page Down and page change, multiple zoom levels to adjust to the screen, opening recent documents at the last page read Downsides of E90 + Adobe Reader LE Phone is large compared to the display It is hard to read the display at sunlight Adobe Reader crashes the phone regularly, zoom could have more levels, doesn't remember last page EDIT: Switched to iPhone and GoodReader. Smaller physical screen width compared to E90 is a disimprovement, but other than that I'm happy. GoodReader is the highest quality smartphone PDF reader I've seen so far.

  • What's the best way to clone multiple PCs from one machine?

    - by Jason T.
    Where I work we have dozens and dozens of old ThinkPad laptops. A lot of these can be reused but not for our needs. They have been long since replaced. The higher-ups have decided to donate them to charity. For better or for worse I have been tasked with reimaging them. I took a laptop and installed the factory copy of Windows, updated it, configured it appropriately. Now I'm trying to reimage it to dozens of other laptops. What's some good software to do this? First I used clonezilla to clone the hdd in the laptop to an internal drive in an external enclosure and it worked. Then I tried taking the base image out and connecting it externally to a laptop that needed to be imaged and I got it to work a few times. So far so good, right? Well once I informed my boss of my findings and what I would want to do then the images started to not work on new laptops. One of three things would happen: The Thinkpads would just blink at me and Windows wouldn't load. Or Windows would load but freeze within two minutes. Last but not least the laptops would BSOD during the Windows XP bootup. These laptops are not going to be used by the company. They're going to charity. So can anyone else recommend a way to reimage multiple laptops?

  • 100% CPU when doing 4 or more concurrent requests with Magento

    - by pancake
    Currently I'm having trouble with a server running Magento, it's unbelievably slow. It's a VPS with a few Magento installations on it used for development, so I'm the only one using them. When I do 4 request all 2 seconds after each other I'm finished in 10 seconds. Slow, but still within the limits of my patience. When I do 4 "concurrent" requests, however (opening 4 tabs in a row, very quickly) all four cores go to 100% and stay there for like a minute. How is this possible? I know that there are a lot of possibilities here, so any tips on how to make an Apache/PHP server go faster are also welcome. It used to go a lot faster before, and I've also tried APC, but it kept causing problems (PHP errors, something with memory pools) so I've disabled it. By the way, the Magento cache is off and compiling is also off. I know this makes Magento slower than usual, but I don't think a 60 second response time is normal for any Magento installation. Virtual hardware: 4 Cores and 4096MB RAM Swap is never used (checked with htop) 100GB disk space, of which 10% is in use Software: Debian 6 DirectAdmin and apache custombuild PHP 5.2.17 (CLI) If you need more info, please tell me how to get it, because I probably don't know how. I do know how to use the command line in linux and the usage of quite a few commands, but my experience with managing a server is limited.

  • WAN Optimization for Small Office/Home Office

    - by TiernanO
    I have been reading up on WAN optimization for the last while, mostly out of interest of speeding up my own internet connections, but also to speed up the office internet connection. At home, I have 2 cable modems plugged into a RouterBoard RB750, which load balances the connections. In the office, we have a single connection into a NetGear router. Most of the WAN Optimization products I have seen, seem to be prohibitively expensive, but also seem to be based on the idea of having multiple branches around the world. What I am looking for, ideally, is as follows: software install: I am "guessing" I need to install it in 2 places: one in the office or house, and one in "the cloud". any connections going to, say, The US (we are in Europe, but our backup's live in the US currently, which would be something important to speed up) would be "tunnelled" though the Optimizer. If downloading or uploading large files, open multiple connections between both "the cloud" and the optimizer... This is where a lot of speed could be gained. finally, for items not compressed, they would be compressed on the cloud side of things, also items that are already on the optimizer could be not sent again. kind of like RSync or Proxy servers... So, is there something that can be done? Is it available using off the shelf components (some magic script with SSH, Squid, Linux and duct tape) or is it something that needs to be purchased? or even an Open Source Project that does 90% of what i am asking?

  • grub refuses to install to raid array

    - by ronno
    I have a software raid 0 setup with dual booting Windows 7 and Ubuntu 12.04. The GRUB bootloader that is already on the hard drive seems to work fine. However, since the latest package update for grub, it refuses to install the new version to the hard disk. grub-install throws the following error: /usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/mapper/< raid name_RAID0p9. Check your device.map. Auto-detection of a filesystem of /dev/mapper/< raid name_RAID0p9 failed. Try with --recheck. If the problem persists please report this together with the output of "/usr/sbin/grub-probe --device-map="/boot/grub/device.map" --target=fs -v /boot/grub" to < [email protected] update-grub pops the same "/usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/mapper/< raid name_RAID0p9. Check your device.map." every alternate line. I don't understand what exactly is going on. I'm afraid to reinstall the grub package because it might mess up the boot, which currently works fine. Is it safe to just ignore this?

  • Looking for a small, portable, port-mirroring ethernet switch.

    - by user37244
    I recently had a mac go haywire, taking half a minute or more to get www.google.com loaded. Getting its owner to give up the machine for repair was like pulling teeth - they were insisting that it must be something to do with the network, since so much had changed with the local configuration at about the same time their box went haywire. I eventually set up a port mirror to a box that I could remote to so I could show that the mac was only irregularly getting packets onto the network. Demonstrating this faced an additional challenge: the latency of the remote desktop software I was using meant that I had to point to timestamps instead of just the moment the packet flashed up on the screen as my evidence. This particular user was the reason this was so challenging this time around, but I would like to have a box that I can cart from desk to desk to use wireshark on my laptop at any station where I need it. 3com, cisco, netgear, etc. (ad nauseum), all make switches that can be configured for port mirroring, but in my case, the smaller, the better. For the sake of my sanity, I'll probably end up running it off a battery anyway. If my laptop had two ethernet ports, this would be easy. So, whaddya recommand for a device that requires 0 configuration at each powerup (though I'm fine with poking at it for a while to set it up initially.) Small, light, and cheap enough to get it past purchasing? Thanks,

  • Can't access shared folder of win8/win7 machine - Error code: 0x80004005. Unspecified Error

    - by ruslan
    It's ironic that I, software engineer with 12 years of experience, continue to have this problem from one version of Windows to another without being able to achive consistent result (sometimes it works). Here it goes again. I have a machine with Win8 Consumer Preview. It doesn't really matter that it's win8. I had same issue with win7 before. On given machine I created local admin user with same name and password I have on second PC (the machine I'm typing this from now). I have two questions to you guys. Why I'm not able to access C$ share of win8 machine from another Win7 machine? I get error that C$ doesn't exist even though it does. Why I'm not able to access share named "test" in Win8 for which Permission set to Full for Everyone. When I attempt to access it from Win7 machine I'm asked to enter username and password. After entering administrator credentials I get error "Windows cannot access \192.168.1.123\test. Error code: 0x80004005. Unspecified Error". Windows Firewall is disabled on Win8 machine for both Private and Public networks. Guest account is disabled. Built-in admin account is enabled. Machine is pingable from other machines.

  • Drowning in documents - recommend doc management solutions?

    - by Martin Day
    I've been researching document management lately. I want to organise my docs at home and also at the office. Finding affordable solutions one can actually test drive is quite hard. Some that I've downloaded just don't seem to work (testing on brand new Vista PC). I've seen some software on Amazon like Paperport but not really sure what they're like. For home I'd like something to organise files, full text search, good scanner integration, nice interface etc. But for the office it seems harder. I need something that does proper workflow and keeps versions. It will have an audit trail. Documents can be approved, checked in/out etc. I know a few clients who would like something similar. It would be great just to import thousands of documents from a shared drive and get them indexed with dupes killed. I'd like to be super clear about how/where the documents are being stored so that maintenance and backups are clear. My Google/twitter searches lead back to the same tired and vague webpages pushing what look like expensive and custom made solutions. Some might be very good I suppose but it's darn hard to tell. I don't mind a hosted package but all in all I don't think something like Google Docs, as good as it is now, will work. There are too many quirks and missing features (as compared to Office). Being able to work directly with the common Office file formats is important. I've noted a similar sounding question asked here back in August but it didn't seem to turn up too many solutions that I could easily and quickly apply. Also there could have been some changes since then so I feel it's worth asking.

  • Faster, secure, protocol/code required for long-distance transfer.

    - by Chopper3
    I've ran into a problem and I'm looking for a new secure protocol/client/server that's faster over a 1Gb/s fibre link - let me tell you the story... I have a pair of redundant, diversely-routed, 1Gb/s links over a distance of around 250 miles or so (not dark fibre but a dedicated point to point link, not a mesh). At the 'client' end I have a HP DL380 G5 (2 x dual-core 2.66Ghz Xeon's, 4GB, Windows 2003EE 32-bit), at the 'server' end I have a HP BL460c G6 (2 x quad-core 2.53Ghz Xeons, 48GB, Oracle Linux 5.3 64-bit). I need to transfer around 500 x 2GB files per week from the client to the server machines per week - but the transfer NEEDS to be secure. Using both iPerf or regular FTP I can get ~80MB/s of transfer pretty consistently, which is great. Using WinSCP or Windows SFTP I can't seem to get more that ~3-4MB/s, at this point the server's CPU is 3% busy while CPU0 of the client goes to ~30% utilised. We've tried editing various TCP window sizes with little success. Both ends are connected to quite low-usage Cisco Cat6509's with Sup720's. I can replace the client machine with a newer machine and/or move it to Linux - but this will take time. Clearly these single-threaded secure Windows clients are introducing too much latency doing their encryption. So a few questions/thoughts; Are there any higher performing secure protocols or client software for Windows that I could try? I'm pretty protocol-gnostic so long as it'll work between Windows and Linux. Should I be using hardware to do the encryption, either in the client or the network parts? If so what would you recommend? I'm not convinced that just swapping the server would be that much faster, the CPU was only at 30% but then again that's higher than I'd have expected given the load - moving to Linux at the client end may be a better idea but would be quite disruptive. Am I missing a trick? Thanks in advance.
