• What's the best way to do user profile/folder redirect/home directory archiving?

  - by tpederson

  My company is in dire need of a redesign around how we handle user account administration. I've been tasked with automating the process. The end goal is to have the whole works triggered by the business, and IT only looking in when there's an error reported. The interim phase is going to be semi-manual. That is a level 2 tech inputs the user's info and supervises the process. The current hurdle I'm facing is user profile archiving. Our security team requires us to archive the profile directories for any terminated user for 60 days in case the legal team requires access to their files. Our AD is as much a mess as everything else, so there are some users with home directories and some with profiles. Anyone who has a profile dir in AD also has a good deal of their profile redirected to our file servers over DFS. In order to complete the process manually you find the user in AD, disable them, find their home/profile dir, go there and take ownership, create an archive folder, move all their files over, then delete the old dir. Some users have many many gigs of nonsense and this can take quite some time. Even automated the process would not be a quick one. I'm thinking that I need to have a client side C# GUI for the quick stuff and some server side batch script or console app to offload this long running process. I have a batch script that works decently using takeown and robocopy, but I wonder if a C# console app would do a better job. So, my question at long last is, what do you think is the best way to handle this? I can't imagine this is a unique problem, how do other admins get this done? The last place I worked was easily 10x larger than the place I'm in now. If we would have been doing this manual crap there, they'd have needed a team of at least 30 full time workers to keep up. I have decent skills in C#.net and batch scripting, but am a quick study and I have used most every language once or twice. Thank you for reading this and I look forward to seeing what imaginative solutions you all can come up with.

• Windows 2003 Storage Server Hanging on Large File Transfers

  - by user25272

  In one of our offices we have a Dell PowerVault 745N NAS device which acts as the main file server. Its running 32bit Windows 2003 Storage Server SP2 with 3GB RAM. The server holds around 60 users HOME folders, which are mapped via AD. The office clients are a mix of XP SP3, Vista and Windows 7. Occasionally the server will completely hang when transferring large files. When the hang happens the console becomes unresponsive with only the mouse active and blank wallpaper. Sometimes stopping the copy frees the server, sometimes not. The hanging can last around 20 minutes. During this time other servers also become unresponsive with blank wallpaper at the console. If you do manage to get onto another server the taskbar and run commands are unresponsive. This also transcends to the client computers sometimes with explorer crashing. I'm guessing this is due to the HOME folder mapping. Eventually the NAS server with free up and everything will be back to normal. The server is configured as follows: PERC 4/DC DATA 2 - 12 SCSI HDD - RAID5 SHADOWCOPY 2 SCSI HDD - RAID1 CERC SATA DATA 11 4 SATA HDD - RAID5 OS 4 SATA HDD - RAID5 All the drivers and firmware is up to date. I've been through all the diagnostics with Dell and the hardware has come up clean including full HDD tests on the arrays. The server has NOD32 installed as the AV, but the hanging happens when it is uninstalled. There are no errors in the event log when this happens and we don't have any errors logged on any of our ProCurve switches. DNS is fine on the domain and AD from what I can tell is running happily. There are no DFS or NFS shares setup either. All the shares are standard Windows. I've unchecked the allow the computer to turn off this device to save power box under Power Management on the NIC. "Set Link Speed and Duplex to Auto-negotiate 1000 " Increased Receive Descriptors buffer from 256 to 352 (reserves more CPU resource for handling data) I've run network traces using network monitor and have found the following: 417 8.078125 {SMB:192, NbtSS:25, TCP:24, IPv4:23} 192.168.2.244 192.168.5.35 SMB SMB:R; Nt Create Andx - NT Status: System - Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND I've tried different cabling; NICs and switch ports all with the same result. Transferring files from other servers on the domain is fine. All I haven't done is run CHKDSK on the drives to look for any file system errors. On the Vista clients I have also run netsh interface tcp set global autotuning=disabled with no result. Could it be that the server has a faulty drive or that the I/O is too much for it to handle? Any ideas why would the hang cause issues with the other servers on the LAN? Many Thanks.

• Is Samba Server what I'm looking for, and if so, what do I need? (currently on DD-WRT Micro)

  - by Anthony

  I am really confused as to what Samba actually does and how it works. Here's what I'm hoping it does: I set up a Samba server on my LAN, and everyone will be able to see each other's shared files and swap them. But some of the documentation makes it sound like it will just allow Mac/Linux computers to see Windows computers. Other bits of the documentation make it sound more like a local server, where a Linux machine would install Samba and they would see everyone and be visible to everyone, but that won't change if anybody else can see each other. While still other things I've read make it seem more like a file-server, where everyone sees each other but file transfers are not peer-to-peer but instead need a host disk for files to act as go between. So, assuming I'm even in the right ballpark of what Samba does in terms of my goal of total cross-visibility on the network, I am left with needing to know what I'd need to set up the server and whether it can be done and is worth it... DD-WRT's article on Samba is a bit ambiguous. One second it sounds as if I can run the server on micro as long as it's set up on a usb drive, but then it also sounds like micro can't run it at all, etc. If I can run it from a usb-connected drive, I still need to know if the files are actually stored on that drive. The dd-wrt article mentions: You can run a Samba server on your main computer and run a client on your router (thus gaining writable storage for the router) or you can use Samba to share a drive connected (typically by USB) to the router among all the computers connected to your network. That one part "to share a drive...among all the computers" makes it sound like the only benefit I get from Samba is a share drive that any OS on the network can see, but they still won't see each other. But I'm very hopeful I'm misreading this. If the computers can see each other but still need the disk, how much space is generally a good idea? I'm basing this on the idea that the drive is a temporary store point. Obviously I'd have to get a drive big enough to store everything people wanted to share if the drive is a full-on file server. If I do have this all wrong, is there any software that achieves what I have in mind? Something that connects to the main router to bridge all clients?

• Dangers of Running Computers w/o Air Conditioning

  - by Daniel Bingham

  I recently moved in to an apartment with out air conditioning. This is fine most of the time as I am in upstate New York. It only ever gets above the high 70s during the hottest of the summer months. And when it does, I'm stubborn enough that I'll just deal with wearing minimal clothing around the house. However, I'm worried about my computers. I'm a software developer and gamer, so many of my machines are very high powered. And at least one of them is a server that must be left on 24/7 (not just a game server - also serves multiple websites). I've never before had to worry about the heat too much, as I always lived in buildings with central air. The in building temperature rarely got much above 70 F. All of the machines I built had good enough air cooling that I never saw a problem. Now the temperature in building is pushing 100F and I'm worried that the machines will not be able to keep themselves cool enough by simply blowing already hot air over themselves. The hottest of them I've turned off. However, the server I cannot. It's an old Dell (not custom build) that runs on a Pentium 4 (2.2GHz). It only has a single hard drive, integrated video. And it'd not running any processor intensive servers. Just basic LAMP. It used to run a MUD server, but that's off for now. So it should be idling most of the time. I haven't been able to find any sort of built in temperature sensors in the hardware... at least not any that the programs I've found in the Debian repository can read. And it's an inherited machine to which I do not have the full specs, so I don't know the tolerances anyway. How worried should I be about it melting down on me? How worried should I be about the hard drive melting or becoming corrupted? To generalize the question for other people, what are the safe temperature tolerances for most machines. How widely does it vary, and how does one go about determining when their machine is running too hot and needs to be shut down?

• Poor performance of single processor 32bit Windows XP xompared SMP in VBA+Excel

  - by Adam Ryczkowski

  Welcome! On many computers I experienced poor performance of 32 bit guests running on 64 bit Linux host (I used only the Debian family). At last I managed to collect benchmark data. I made the benchmark by running custom VBA macro, (which we use in our company) that generates 284 pages long Word document full of Excel Pie charts, tables and comments. The macro is run as a single task (excluding the standard services) on a set of identically configured Windows XP 32-bit systems. I measured the time (in sec.) needed to perform the test. The computer (i.e. my notebook Asus P53E) supports both VT-d extensions and native Windows XP. It has 2-core processor, each core is hyperthreaded, so in total we have 4 mostly independent execution units. I use the latest VirtualBox 4.2 and VMWare Workstation 9.0 for Linux, installed together on the same host (running Mint 13 Maya) but never run simultaneously. The results (in column Time) are no less accurate than ± 10% Here are the results (sorry for the format, but I couldn't find out a better solution for tables in SO): +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ | Host software | # processor | Windows kernel | IO APIC | VT-x/AMD-V | 2D Video Accel | Time | +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 1 | 0 | 1139 | | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 1 | 1 | 1050 | | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 0 | 1 | 1644 | | VirtualBox | 4 | ACPI Multiprocessor PC | 1 | 1 | 1 | 6809 | | VMWare | 1 | ACPI Uniprocessor PC | | 1 | 1 | 1175 | | VMWare | 4 | ACPI Multiprocessor PC | | 1 | 1 | 3412 | | Native | 4 | ACPI Multiprocessor PC | | | | 1693 | | Native | 1 | Advanced Configuration and Power Interface (ACPI) PC | | | | 1170 | +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ Here are the striking conclusions: Although I've read in the VirtualBox fora about abysmal performance with 32-bit guest on 64-bit host, VMWare also has problems compared to native run, still being twice faster(!) than VBox. Although VBA is inherently single-threaded, the Excel calculations, which take much more than a half of total computation time, supposedly aren't. So one would expect some speed gain when running on 2+ cores ("+" for hyperthreading). What we see is a speed loss. And quite big one too. For the VirtualBox the VT-d extension isn't a big deal. Can anyone shed some light on why the singlethreaded Windows kernel is so much faster than the SMP one?

• Radeon HD4850 serious issues when using DirectX 10

  - by ricsmania

  Hello, I have a problem with my video card. Whenever I run a DirectX 10 game, it works for a few seconds (10 or so) and then starts displaying nothing but big polygons. I have tested this with Crysis and Resident Evil 5, both have the same problems. The same games running under DirectX 9 work fine, except for some small black squares once in a while. I have the following specs: Asus P7P55D LE Intel Core i5 750 Sapphire Radeon HD4850 1GB 2x2GB Patriot Viper II Sector 5, DDR3 1600 MHz OCZ Stealth X Stream 500SXS 500W At first I thought it could be the video card overheating (it has stock cooling), but the game crashes even when it's running at 50 degrees C, and it's never been higher than 70. I also thought it could be the PSU, but as far as I know 500W is enough for this computer, especially because I haven't overclocked anything. My OS is Windows 7 X64 and I am using Catalyst 10.10, but I have also tried many older versions with no success. I don't think there is a problem with the card itself, or else it wouldn't run DirectX 9 games I believe. I have spent many hours searching for a solution but I couldn't, so any help is appreciated. Thank you. EDIT: I did some further investigation about the problem, and it seems taspeotis was right, it might be related to memory. I slightly underclocked the memory from 993 to 965 MHz and the problem went away completely. Both the black squares using DirectX 9 and the weird polygons using DirectX 10. I was using RE DirectX 10 Benchmark, as it consistently crashed around the same point, and now I can play the full benchmark with no artifacts at all. Unfortunately, the underclock has an obvious hit in performance. Although it's not critical, it's definitely noticeable. So, if the video memory test software showed no erros, but the card needs an underclock to work, what might be the problem? Temperature? Voltage? By the way, I couldn't find what the default voltage for this card is. And what is a good software to try and increase it? I tried Ati Tray Tools but it has a bug that increases the clock speed dramatically whenever I change something in the Overclock tab, so I'm afraid it might fry my card. Worst case scenario, if I don't find I solution I will try to slightly increase the GPU clock to compensate for the memory clock. Thank you again.

• Newly configured MSSQL2008, TIME_WAIT but no ESTABLISHED?

  - by 3molo

  Windows 2008 R2, standard. No firewall locally on it. Newly setup because an old SQL2000 had two disks die (or could it be the raid controller?) at the same time. Luckily, I had fresh backups. The databases have been restored, and SP2 for SQL2008 applied. I can see various hosts trying to establish a session, but the (customer) sites does not work and I don't see the expected established sessions. A wireshark reveals a full three-way handshake. Since it's customer machines connecting, I cannot logon to them and restart application pools.. What on earth could be causing this?

• batch file infinite loop when parsing file

  - by Bart

  Okay, this should be a really simple task but its proving to be more complicated than I think it should be. I'm clearly doing something wrong, and would like someone else's input. What I would like to do is parse through a file containing paths to directories and set permissions on those directories. An example line of the input file. There are several lines, all formatted the same way, with a different path to a directory. E:\stuff\Things\something else (X)\ (The file in question is generated under Cygwin using find to list all directories with "(X)" in the name. The file is then passed through unix2win to make it windows compatible. I've also tried manually creating the input file from within windows to rule out the file's creation method as the problem.) Here's where I'm stuck... I wrote the following quick and dirty batch file in Windows XP and it worked without any issues at all, but it will not work in server 2k8. Batch file code to run through the file and set permissions: FOR /F "tokens=*" %%A IN (dirlist.txt) DO echo y| cacls "%%A" /T /C /G "Domain Admins":f "Some Group":f "some-security-group":f What this is SUPPOSED to do (and does in XP) is loop through the specified file (dirlist.txt) and run cacls.exe on each directory it pulls from the file. The "echo y|" is in there to automagically confirm when cacls helpfully asks "are you sure?" for every directory in the list. Unfortunately, however, what it DOES is fall into an infinite loop. I've tried surrounding everything after "DO" with quotes, which prevents the endless loop but confuses cacls so it throws an error. Interestingly, I've tried running the code from after "DO" manually (obviously replacing the variable with the full path, copied straight from the file) at a command prompt and it runs as expected. I don't think it's the file or the loop, as adding quotes to the command to be executed prevents the loop from continuing past where it's supposed to... I really have no idea at this point. Any help would be appreciated. I have a feeling it's going to be something increadibly stupid... but I'm pulling my hair out so I thought I'd ask.

• Failed to start up after upgrading software in ubuntu 10.10

• LdapErr: DSID-0C0903AA, data 52e: authenticating against AD '08 with pam_ldap

  - by Stefan M

  I have full admin access to the AD '08 server I'm trying to authenticate towards. The error code means invalid credentials, but I wish this was as simple as me typing in the wrong password. First of all, I have a working Apache mod_ldap configuration against the same domain. AuthType basic AuthName "MYDOMAIN" AuthBasicProvider ldap AuthLDAPUrl "ldap://10.220.100.10/OU=Companies,MYCOMPANY,DC=southit,DC=inet?sAMAccountName?sub?(objectClass=user)" AuthLDAPBindDN svc_webaccess_auth AuthLDAPBindPassword mySvcWebAccessPassword Require ldap-group CN=Service_WebAccess,OU=Groups,OU=MYCOMPANY,DC=southit,DC=inet I'm showing this because it works without the use of any Kerberos, as so many other guides out there recommend for system authentication to AD. Now I want to translate this into pam_ldap.conf for use with OpenSSH. The /etc/pam.d/common-auth part is simple. auth sufficient pam_ldap.so debug This line is processed before any other. I believe the real issue is configuring pam_ldap.conf. host 10.220.100.10 base OU=Companies,MYCOMPANY,DC=southit,DC=inet ldap_version 3 binddn svc_webaccess_auth bindpw mySvcWebAccessPassword scope sub timelimit 30 pam_filter objectclass=User nss_map_attribute uid sAMAccountName pam_login_attribute sAMAccountName pam_password ad Now I've been monitoring ldap traffic on the AD host using wireshark. I've captured a successful session from Apache's mod_ldap and compared it to a failed session from pam_ldap. The first bindrequest is a success using the svc_webaccess_auth account, the searchrequest is a success and returns a result of 1. The last bindrequest using my user is a failure and returns the above error code. Everything looks identical except for this one line in the filter for the searchrequest, here showing mod_ldap. Filter: (&(objectClass=user)(sAMAccountName=ivasta)) The second one is pam_ldap. Filter: (&(&(objectclass=User)(objectclass=User))(sAMAccountName=ivasta)) My user is named ivasta. However, the searchrequest does not return failure, it does return 1 result. I've also tried this with ldapsearch on the cli. It's the bindrequest that follows the searchrequest that fails with the above error code 52e. Here is the failure message of the final bindrequest. resultcode: invalidcredentials (49) 80090308: LdapErr: DSID-0C0903AA, comment: AcceptSecurityContext error, data 52e, v1772 This should mean invalid password but I've tried with other users and with very simple passwords. Does anyone recognize this from their own struggles with pam_ldap and AD? Edit: Worth noting is that I've also tried pam_password crypt, and pam_filter sAMAccountName=User because this worked when using ldapsearch. ldapsearch -LLL -h 10.220.100.10 -x -b "ou=Users,ou=mycompany,dc=southit,dc=inet" -v -s sub -D svc_webaccess_auth -W '(sAMAccountName=ivasta)' This works using the svc_webaccess_auth account password. This account has scan access to that OU for use with apache's mod_ldap.

• Wirelss card not being detected in backtrack 5

  - by Jesse Nelson

  I just installed backtrack 5 and I am unable to detect my wireless card. iwconfig doesn't list my interface. I can see that the hardware is present in lspci -vnn (see below) but I can't get the interface detected. I have tried to reinstall the compat-wireless package but I get errors during the build (see below) I have done a ton of researching and I keep hitting a brick wall, mostly because the wiki for backtrack is down and I can't find any good resources. Does anyone know how to fix the issue? Also, does anyone no how I can scan the hardware to determine what NIC is assigning my interface? If I can figure out the interface name I think I can set it up manually by putting up the link and using wireless-tools to manually configure the connection, this is what I had to do in arch on my mac. As stated the wiki for backtrack is down and I can't find any help on the issue. I tried to do the full kernel upgrade suggested in my software update but after the update was complete and I logged back in I had a new log in manager and the only thing I was able to log into was window managers. However, after this update my wireless was working fine. Please help I am new to Linux and the wiki is down, I have nowhere else to turn. Forgot to mention I am using the KDE version, not Gnome.

• Why did Intel drop the Itanium?

  - by Cole Johnson

  I was reading up on the history of the computer and I came along the IA-64 (Itanium) processors. They sounded really interesting and I was confused as to why Intel would decide to drop them. The ability to choose explicitly what 2 instructions you wanted to run in that cycle is a great idea, especially when writing your program in assembly, for example, a faster bootloader. The hundreds of registers should be convincing for any assembly programmer. You could essentially store all the functions variables in the registers if it doesn't call any other ones. The ability to do instructions like this: (qp) xor r1 = r2, r3 ; r1 = r2 XOR r3 (qp) xor r1 = (imm8), r3 ; r1 = (imm8) XOR r3 versus having to do: ; eax = r1 ; ebx = r2 ; ecx = r3 mov eax, ebx ; first put r2 into r1 xor eax, ecx ; then set r1 equivalent to r2 XOR r3 or ; SAME mov eax, (imm32) ; first put (imm32) into r1 xor eax, ecx ; then set r1 equivalent to (imm32) XOR r3 I heard it was because of no backwards x86 comparability, but couldn't thy be fixed by just adding the Pentium circuitry to it and just add a processor flag that would switch it to Itanium mode (like switching to Protected or Long mode) All the great things about it would have surly put them a giant leap ahead of AMD. Any ideas? Sadly this means you will need a very advanced compiler to do this. Or even one per specific model of the CPU. (E.g. a newer version of the Itanium with an extra feature would require different compiler). When I was working on a WinForms (target only had .NET 2.0) project in Visual Studio 2010, I had a compile target of IA-64. That means that there is a .NET runtime that was able to be compiled for IA-64 and a .NET runtime means Windows. Plus, Hamilton's answer mentions Windows NT. Having a full blown OS like Windows NT means that there is a compiler capable of generating IA-64 machine code.

• SSH: Port Forwarding, Firewalls, & Plesk

  - by Kian Mayne

  I edited my SSH configuration to accept connections on Port 213, as it was one of the few ports that my work firewall allows through. I then restarted sshd and everything was going well. I tested the ssh server locally, and checked the sshd service was listening on port 213; however, I still cannot get it to work outside of localhost. PuTTY gives a connection refused message, and some of the sites that allow check of ports I tried said the port was closed. To me, this is either firewall or port forwarding. But I've already added inbound and outbound exceptions for it. Is this a problem with my server host, or is there something I've missed? My full SSH config file, as requested: # $OpenBSD: sshd_config,v 1.73 2005/12/06 22:38:28 reyk Exp $ # This is the sshd server system-wide configuration file.

• Graphics card artifacting

  - by White Phoenix

  This is my current build: EVGA X58 (first generation) motherboard Intel i7 965 @ stock clocks 3x 2GB DDR3-1600 Corsair RAM at stock timings and voltages Corsair AX750 80 Plus Gold PSU 1 Optical Drive 1 Seagate 7200.10 500 GB drive 2x Western Digital Caviar Black 1 TB drives OCZ Vertex 1 60 GB EVGA GTX 460 Antec 1200 case HT-Omega Striker 7.1 Sound Card Windows 7 32-bit Professional (PAE Enabled) My graphics card started artifacting while I was playing a game. It artifacted, the display blinked, then I got an NVIDIA driver has crashed and recovered message. Kept going, more artifacts, another crash, but this time my display blanked out and I couldn't do anything. Restarted my computer - artifacting is in the BIOS - got to Windows 7 but it BSOD'd before I could even log in. I restarted the computer again - artifacts cleared themselves out and I managed to get to Win7, but it soon started blinking in and out and artifacting again. Checked the card temps and they're well within range. (50 idle, 70 full load) The ambient temperature here is about 80-85F with high humidity. Tried Safe Mode and it still froze up/BSOD'd. Already tried the following to fix this problem: - Reseat the graphics card and swapped in a different slot. - Removed cover on card and sprayed with compressed air to clean it out. - Swapped around memory and/or went with only using one stick at a time. - Underclocked card I called EVGA Tech Support and they said that the voltage on the 12V rail of my Corsair AX750 PSU was on the high end of the "acceptable" range (12.4V, highest within acceptable range is 12.6V - optimal is obviously 12V). They gave me an RMA number anyway, but I want to get a second opinion from you all before I send this thing off, as shipping from where I live to EVGA is kind of pricey. This PSU is only 6 months old. So that I don't have to play RMA tag, which case would be most likely? I'm strapped for cash at the moment so I want to reduce the amount of RMAs I have to do since shipping is expensive here. Is there any surefire way to test to see if it's really the graphics card or the PSU? I tried unplugging any devices that were connected to the 12V rail (except for my SSD and graphics card) as I do have 3 mechanical hard drives, but the voltage for that rail didn't drop (it remained at 12.4V). I'm fairly sure it isn't the drivers since I'm getting the artifacting at the BIOS too. Right now I'm back in Windows 7 but I don't know for how long until it messes up again. Any ideas?

• Synchronize the same set of files to 2 different locations with 2 different programs for 2 different purposes

  - by Hedgetrimmer

  Because of stupid questionable IT policies at my not-to-be-named place of occupation, I have been (and will be, for the forseeable future) carrying on an external hard drive a unison-synchronized copy of all of my documents and code, including code which resides in some of my "dotfiles" and other code which resides in ~/bin (things I've made are there because ~/bin is in my $PATH) along with some cruft generated (and to be generated) by conscript and its related "giter8" templating system for Scala project boilerplates. Despite this, I do use a symlinking program to store all of my important dotfiles in a subdirectory. Thanks to that somewhat complicated setup, I have resorted to making a directory full of symlinks to every directory (or file, as is the case with stuff under ~/bin) that I want synchronized, and then follow = True is in my unison profile. It happens to be that this collection of odds and ends—plus an automatically-generated text file containing every package installed on my system—is everything under ~ that needs to be backed up to a remote (rsync-over-ssh) host with client-side encryption and signing from GPG. I already believe that duplicity is the most appropriate program to do that. What isn't as clear-cut is how to make duplicity use the exact same set of files when it runs a backup; it would be simple if duplicity would follow symlinks, but it does not and the manpage lists no option for enabling any such behavior. Comparing unison's file selection algorithm to duplicity's, I don't think I can write a program that could compute a ruleset for one program given one for the other. For the record, I would rather not keep the symlinks manually synchronized with duplicity file-selection rules, as they can change thanks to the above-mentioned complications regarding ~/bin. I don't think running duplicity on the external hard disk is such a good idea either; I usually keep that hard disk unmounted and unplugged in case of a power failure or other physical problem with the computer, plus I'm not sure about duplicity's performance given that: the hard disk is NTFS-formatted in order to be useable at my Windows-imprisoned place of occupation. despite being a USB 3.0 disk, my computer has no USB 3.0 ports so it acts as a USB 2.0 disk. How can I have duplicity (or is there a better program that I have overlooked?) back up the exact same set of files that is bidirectionally synchronized with my external hard disk?

• IPv6 routing to another interface

  - by Robert

  I'm trying to get an IPv6 enabled router to forward data from one interface to the other and I'm having issues. When following this example (http://www.cisco.com/en/US/tech/tk872/technologies_configuration_example09186a0080ba6106.shtml) I am able to get full connectivity between all 3 routers in my simulator. However when I try to use only 1 router; I can't get connectivity to the other interfacs on the same router. My PC is directly attached to FA 0/1 and it can ping the router's interface. However it can not ping any other interface on the router(which unless I'm missing something it should be able to do). The router on the other hand can ping everything. I thought static routes might help; but the router already has routes for everything. I'm thinking the packet should come in; router looks up the destination in it's ipv6 routing table and then realizes it's for itself, and should respond. I thought maybe it couldn't respond directly; so I tried pinging a device like 2001:0000:0000:1000::2, but i don't get a response. I'm running on IOS 12.4. I'm missing something(hopefully simple), but I just can't see what it is. With only 1 router; how do I enable my PC to talk to the other subnets? Thank you in advance, Robert Topology: R1 FA 0/0: 2001:0000:0000:0000::1/52 FA 0/1: 2001:0000:0000:1000::1/52 FA 1/0: 2001:0000:0000:2000::1/52 Loopback 0: 2001:0000:0000:3000::1/52 PC: 2001:0000:0000:2000::2/52 PC plugs directly into FA 1/0 on the router. --- Configuration --- ipv6 cef ipv6 unicast routing interface Loopback0 no ip address ipv6 address 2001:0000:0000:3000::1/52 ipv6 enable ! interface FastEthernet0/0 no ip address duplex auto speed auto ipv6 address 2001:0000:0000::1/52 ipv6 enable ! interface FastEthernet0/1 no ip address duplex auto speed auto ipv6 address 2001:0000:0000:1000::1/52 ipv6 enable ! interface FastEthernet1/0 no ip address duplex auto speed auto ipv6 address 2001:0000:0000:2000::1/52 ipv6 enable --- end of config --- --- routing table --- IPV6Lab#show ipv6 route IPv6 Routing Table - 10 entries Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP U - Per-user Static route I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2 ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2 C 2001:0000:0000::/52 [0/0] via ::, FastEthernet0/0 L 2001:0000:0000::1/128 [0/0] via ::, FastEthernet0/0 C 2001:0000:0000:1000::/52 [0/0] via ::, FastEthernet0/1 L 2001:0000:0000:1000::1/128 [0/0] via ::, FastEthernet0/1 C 2001:0000:0000:2000::/52 [0/0] via ::, FastEthernet1/0 L 2001:0000:0000:2000::1/128 [0/0] via ::, FastEthernet1/0 C 2001:0000:0000:3000::/52 [0/0] via ::, Loopback0 L 2001:0000:0000:3000::1/128 [0/0] via ::, Loopback0 L FE80::/10 [0/0] via ::, Null0 L FF00::/8 [0/0] via ::, Null0 --- end of routing table ---

• How to circumvent ISP Limiting "Unknown" traffic - (SSH)Proxy, VPN

  - by connery

  I am having issues with using a proxy/VPN, with my current ISP (Comenersol, Spain). From my point of view they limit traffic by protocol or by traffic they "know" and "dont know". I'll explain my findings so far below. Internet connection in Spain: ~400-420KByte/sec (speedtest.net) OpenVPN Server in Sweden(pfsense): 100/100Mbit. LZO Compression. TCP. Tun. Aes128 Squid Proxy server in Sweden (pfsense): 100/100 (same box as the vpn server). Plain, no encryption. Runs in stealth mode to hide the use of proxy. NOT running OpenVPN or Squid Proxy, this is my findings: When I download a file from my pfsense box in Sweden, I get maximum speed When I run speedtest.net and choose any european server (including Swedish), I get max speed When I download a torrent (with non default port above 10K), I get limited to ~100KByte/sec. Encryption is turned off If I download something through https, I get max speed Running either Squid Proxy or VPN, this is my findings When I download a file from my pfsense box in Sweden, I get ~100KByte/sec When I run speedtest.net and choose any european server (including Swedish and Spanish), I get ~100Kbyte/sec When I download a torrent, I get same limitation ~100KByte/sec When I download something through https, I get ~100KByte/sec I verify the speeds above with speedtest.net measure, firefox measure in addition to having bmon running in terminal in the background. This way I am certain that the speeds I get presented, are in fact correct. If I connect through a different ISP with VPN or Squid Proxy, I get better speeds (400KByte/sec ++) In short: Whenever I tunnel my traffic through Sweden, my SPanish ISP throttles the traffic. I thought tunneling it through Squid would solve the issue, since I then would no longer hide my traffic through encryption. This does not seem to be the case. Wget and fetch gives same result. I did not try 'nc', but I assume this would give the same result. Does anyone know how to circumvent this issue? I would very much like to be able to get full speed with Swedish ip, as this would make me able to stream TV at higher quality than today. 100KByte/sec just does not cut it quality wise. Thanks for reading. Looking forward for your help.

• Alternative Windows Offline Files + Windows Backup + Previous Version Setup

  - by Herson

  Currently our documents are all hosted in a Windows 7 box. Users can access the files using Windows share and the documents are available offline (windows 7 feature). The documents are being backed up daily by Windows 7 backup and restore utility. Users can access previous versions of the file (from the backups) using Windows Explorer "previous versions" feature. This setup is currently working well, except for the following: We would prefer to have access to hourly versions of the file, not daily. The previous version mechanism is tied up to the backup mechanism. Windows 7 performs a full backup every week and incremental backup everyday. The previous versions of a file is actually what are the available in the backups. If you 20GB documents and want to maintain at least three(3) year history, you will use at minimum 3 years * 52 weeks * 20GB or about 3TB even if there are few changes in the documents. Its pretty inefficient use of space. Looking up previous versions of a file is very slow (tens of minutes). This is probably related to the previous issue - Windows has to traverse its all of its backups. I am considering using SVN + autocommit/autoupdate tortoisesvn. It will have the following advantages: Backups are easy and will also backup the whole history of each documents. (Just backup the repository). Creating previous versions can be frequent. I think svn commit / update can be done every two minutes or so. Users can sync over the net. However, I can see the following issues: More conflicts than the original setup because both multiple users can now edit the same file even both are online, i.e. can connect to the SVN repo. The users can off course lock the file first before editing, but that would mean they have to adjust. Delay on propagation of file changes. On windows 7 file sharing, changes made by one online user will be instantaneously available to other online users. With the SVN setup, changes will only be propagated when the users execute the svn add/commit/update sequence. Delay will be probably a few minutes. This workflow will no longer work: "Hi, I just edited document X, can you have a quick look?" I would like to ask the opinion of the community for alternative setups, or improvements on the above setups to work out the kinks.

• Triple (3) Monitors under Linux

  - by widgisoft

  I have a 3 monitor setup (each 1680x1050) via an Nvidia NVS440 (2 GPUs, 2 outputs per GPU totalling 4 outputs); this works fine under Windows XP,7 but caused considerable headaches under Linux (Ubuntu 9.04). I had previously used an XFX 9600GT and the onboard XFX 9300GS to produce the same result but the card was noisy and power hungry and I was hoping that there was some magical switch in the NVS4400 that got rid of this annoying problem - turns out the NVS440 is just 2 cards on one physical PCB :-p (I searched the net high and low for people using this card under Linux but found nothing, if anything the card uses less power and is fan less so I was to benefit from it either way) Anyway, using either set up there were 5 solutions available: Have 3 separate X instances, all un joined Have 3 separate X instances, adjoined by Xinerama Have 2 separate X instances - One using twin-view, both adjoined by Xinerama Have 2 separate X instances - One using twin-view but no Xinerama Have a single Twin-view setup and leave the 3rd screen unplugged :-p The 4rd option, using 2 separate X instances and twinview (but no xinerama) was the best balance in terms of performance and usability but caused 2 really annoying issues You couldn't control (without altering the shortcuts) which screen an application opened onto - and once it was opened you couldn't move it to another screen without opening up terminal and forcing it to move Nvidia's overriding or falsifying of Xinerama breaks and the 2 screens joined by Twin view behave like a single huge screen causing popups to open in the middle of both screens and maximising of windows stretches to the width of the first 2 screens Firefox can only run one instance as the same user so having multiple firefox windows requires at least 2 users The second option "feels" like the right option, but OpenGL is basically disabled and playing any sort of game or even running anything graphical causes a huge performance drop and instability - even trying to run a basic emulator for gba or gens just causes the system to fall over. It works just enough to stare at your desktop and do nothing but as soon as you start doing some work - opening windows, dragging things around - running multiple copies of firefox it just really feels slow. The last open, only going dual screen works perfectly and everything performs as required, full GPU acceleration - two logical screen spaces - perfect, just make it work across GPUs like windows! :-p Anyway, I know RandR was supposed to pick up the slack when it would introduced GPU objects of sorts to allow multiple GPUs to be stitched together to create one huge desktop at a much deeper layer than Xinerama. I was wondering if this has now been fixed (I noticed X server 1.7 is out) and whether anyone has got it running successfully? Again, my requirements are: One huge desktop to drag any window across Maximising of windows to each screen (as XP does) Running fullscreen apps on the primary screen and disabling the mouse from moving onto the others or on all 3 stretched Finally as a side note; I am aware of the Matrox triple (and dual) head splitter but even the price they go for on eBay is more than I can afford atm, my argument: I shouldn't have to buy extra hardware to get something to work on Linux when it's something that's existed in the windows world for a long time (can you tell I don't get on with X :-p); If I had the cash I'd have bought the latest version of this box already (the new version finally supports large resolutions as the displays I have 1680x1050 each).

• Windows 7 & Virtual PC and Internet (gateway) problems on host PC

  - by Mufasa

  I upgraded to Windows 7 on a PC that is a few years old. The CPU was one revision away from having Hyper-V on it. So, I had to install Microsoft Virtual PC 2007 (v6.0.156.0) to run full XP instances instead of the seamless XP virtualization that is advertised so much. That's fine though; the 'older' version is useful since I use it to run different versions of the whole XP/IE stack for testing. (I'm a web developer.) ...And for the one 16-bit application we still use at the office for scheduling. * sigh * The virtual instances work fine, including networking. My issue is that after a reboot or coming out of sleep mode, my host Windows 7 won't connect to the Internet. It will connect to the local network fine. If I disable the "Virtual Machine Network Services" item (I'll call "VMNS" from here on) in the LAN Connection properties box, it starts working. But than the Virtual PC instances lose their network connectivity. If I re-enable VMNS again in the same instance, everything works (Internet on host and in the virtualized instances). But after the next reboot/sleep cycle this starts over. The route table gave me a clue though. When doing a cycle w/ VMNS enabled: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 On-link 10.0.3.51 20 0.0.0.0 0.0.0.0 10.0.10.10 10.0.3.51 276 ... After VMNS is disabled, the first route goes away. I assume that is for VMNS to intercept virtualized instance's network connections and forward them correctly? Just a guess though. More info: I checked my Firewall settings and Services (because I'm sort of a control nazi and turn off a lot) but couldn't find anything that made sense and if turned on changed anything. So it might be something there I'm missing, but I don't know what. My current hacked solution: So, I figured I'd mess with the routes myself to see if that helped, it did. If I run a route delete 0.0.0.0 on the universal (0.0.0.0) gateway routes, and add back in just the 2nd line with route add 0.0.0.0 mask 0.0.0.0 10.0.10.10--the one that points to my actual gateway (10.0.10.10)--then I don't have to mess with the disable/enable cycle of VMNS, and everything works. Running those two commands is faster then bringing up connection options and disabling and re-enabling VMNS, but I still don't want to have use that hack script every boot either. (Oh, and I also tried messing with hard-coding TCP/IP settings in my network adapter, including setting high metrics, etc., but that didn't help either.) Any suggestions on the right way to fix this?

• A gigabit network interface is CPU-limited to 25MB/s. How can I maximize the throughput?

  - by netvope

  I have a Acer Aspire R1600-U910H with a nForce gigabit network adapter. The maximum TCP throughput of it is about 25MB/s, and apparently it is limited by the single core Intel Atom 230; when the maximum throughput is reached, the CPU usage is about 50%-60%, which corresponds to full utilization considering this is a Hyper-threading enabled CPU. The same problem occurs on both Windows XP and on Ubuntu 8.04. On Windows, I have installed the latest nForce chipset driver, disabled power saving features, and enabled checksum offload. On Linux, the default driver has checksum offload enabled. There is no Linux driver available on Nvidia's website. ethtool -k eth0 shows that checksum offload is enabled: Offload parameters for eth0: rx-checksumming: on tx-checksumming: on scatter-gather: on tcp segmentation offload: on udp fragmentation offload: off generic segmentation offload: off The following is the output of powertop when the network is idle: Wakeups-from-idle per second : 61.9 interval: 10.0s no ACPI power usage estimate available Top causes for wakeups: 90.9% (101.3) <interrupt> : eth0 4.5% ( 5.0) iftop : schedule_timeout (process_timeout) 1.8% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 0.9% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 0.5% ( 0.6) <kernel core> : neigh_table_init_no_netlink (neigh_periodic_timer) And when the maximum throughput of about 25MB/s is reached: Wakeups-from-idle per second : 11175.5 interval: 10.0s no ACPI power usage estimate available Top causes for wakeups: 99.9% (22097.4) <interrupt> : eth0 0.0% ( 5.0) iftop : schedule_timeout (process_timeout) 0.0% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 0.0% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 0.0% ( 0.6) <kernel core> : neigh_table_init_no_netlink (neigh_periodic_timer) Notice the 20000 interrupts per second. Could this be the cause for the high CPU usage and low throughput? If so, how can I improve the situation? As a reference, the other computers in the network can usually transfer at 50+MB/s without problems. A computer with a Core 2 CPU generates only 5000 interrupts per second when it's transferring at 110MB/s. The number of interrupts is about 20 times less than the Atom system (if interrupts scale linearly with throughput.) And a minor question: How can I find out what is the driver in use for eth0?

• Can Remote Desktop Services be deployed and administered by PowerShell alone, without a Domain in WIndows Server 2012 and 2012 R2?

  - by Warren P

  Windows Server 2008 R2 allowed deployment of Terminal Server (Remote Desktop Services) without a domain, and without any insistence on domains. This was very useful, especially for standalone virtual or cloud deployments of a server that is managed remotely for a remote client who has no need or desire for any ActiveDirectory or Domain features. This has become steadily more and more difficult as Microsoft restricts its technologies further and further in each Windows release. With Windows Server 2012, configuring licensing for Remote Desktop Services, is more difficult when not on a domain, but possible still. With Windows Server 2012 R2 (at least in the preview) the barriers are now severe: The Add/Remove Roles and Features wizard in Windows Server 2012 R2 has a special RDS deployment mode that has a rule that says if you aren't on a domain you can't deploy. It tells you to create or join a domain first. This of course comes in direct conflict with the fact that an Active Directory domain controller should not be the same machine as a terminal server machine. So Microsoft's technology is not such much a Cloud Operating System as a Cluster of Unwanted Nodes, needed to support the one machine I actually WANT to deploy. This is gross, and so I am trying to find a workaround. However if you skip that wizard and just go check the checkboxes in the main Roles/Features wizard, you can deploy the features, but the UI is not there to configure them, and when you go back to the RDS configuration page on the roles wizard, you get a message saying you can not administer your Remote Desktop Services system when you are logged in as a Local-Computer Administrator, because although you have all admin priveleges you could have (in your workgroup based system), the RDS configuration UI will not accept those credentials and let you continue. My question in brief is, can I still somehow, obtain the following end result: I need to allow 10-20 users per system to have an RDS (TS) session. I do not need any of the fancy pants RDS options, unless Microsoft somehow depends on those features being present. I believe I need the "RDS Session Host" as this is the guts of "Terminal Server". Microsoft says it is "full Windows desktop for Remote Desktop Services client. I need to configure licensing so that the Grace Period does not expire leaving my RDS non functional, so this probably means I need a way to configure TS CALs. If all of the above could technically be done with the judicious use of the PowerShell, I am prepared to even consider developing all the PowerShell scripts I would need to do the above. I'm not asking someone to write that for me. What I'm asking is, does anyone know if there is a technical impediment to what I want to do above, other than the deliberate crippling of the 2012 R2 UI for Workgroup users? Would the underlying technologies all still work if I manipulate and control them from a PowerShell script? Obviously a 1 word Yes or No answer isn't that useful to anyone, so the question is really, yes or no, and why? In the case the answer is Yes, then how.

• What are the most likely bottlenecks determining the performance of CamStudio screen recording?

  - by Steve314

  When doing screen recording, I can get a frame rate of maybe 15 frames per second for the full screen on my 1080p monitor using the XVID codec. I can increase the speed a bit by recording a region, changing screen modes, and tweaking other settings, but I'm curious what hardware upgrades might give me the biggest bang for my buck. My PC is budget, but modern... Athlon 2 X4 645 (3.1GHz, quad core, limited cache) processor. 4GB single channel DDR3 1066 RAM. ASRock motherboard with NVidia GeForce 7025/nForce 630a Chipset. ATI Radeon HD 5450 graphics card - 512MB on board, not configured to steal system RAM. I dual-boot Windows XP and Windows 7. For the moment, XP is my bigger performance concern as it's still my getting-things-done O/S as opposed to my browser-host O/S. My goal is to make a few programming-related tutorials. For a lot of that I don't need screen recording - I can make up some slides, record audio with the PC switched off, yada yada. When I do need screen recording, I'll mostly be recording Notepad++, Visual Studio or a command prompt. Occasionally, I may be recording some kind of graphics or diagram program and using my pre-Bamboo cheap Wacom tablet - I have the CS2 versions of Photoshop and Illustrator, but I'd much more likely be using Microsoft Paint. Basically, what I'll be recording won't be making huge demands on the machine - but recording a fair number of pixels (720p preferred) will be useful. What's particularly wierd - not so long ago I still had a five-year-old Pentium 4 based PC. And (with the same 1080p monitor) it could record at not far from the same frame rate. So clearly the performance issues are more subtle than just throw-money-at-it. My first guess would be that the main bottleneck is the bandwidth for transferring data to/from the graphics card. Is that likely to be correct? In support of that, see this [Radeon HD 5450 review][1] - the memory bandwidth is only 12.8 GB/s. If you can't get data out of graphics memory quickly, you can't transfer it back to the system memory quickly. Apparently, that's slower than some top-end cards in 2002.

• Can only bring up one of two interfaces

  - by mstaessen

  I'm having a bizarre issue with my HP Proliant DL 360 G4p server. It has two gigabit ethernet interfaces but I can bring up only one of them. This is starting to freak me out and that's why I turned here. I'm running the x64 ubuntu 11.10 server edition. lshw -c network shows that the second interface is disabled. I have no idea why ans how to enable it. $ sudo lshw -c network *-network:0 description: Ethernet interface product: NetXtreme BCM5704 Gigabit Ethernet vendor: Broadcom Corporation physical id: 2 bus info: pci@0000:02:02.0 logical name: eth0 version: 10 serial: 00:18:71:e3:6d:26 size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 66MHz capabilities: pcix pm vpd msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.119 duplex=full firmware=5704-v3.27b, ASFIPMIc v2.36 ip=10.48.8.x latency=64 link=yes mingnt=64 multicast=yes port=twisted pair speed=100Mbit/s resources: irq:25 memory:fdf70000-fdf7ffff *-network:1 DISABLED description: Ethernet interface product: NetXtreme BCM5704 Gigabit Ethernet vendor: Broadcom Corporation physical id: 2.1 bus info: pci@0000:02:02.1 logical name: eth1 version: 10 serial: 00:18:71:e3:6d:25 capacity: 1Gbit/s width: 64 bits clock: 66MHz capabilities: pcix pm vpd msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.119 firmware=5704-v3.27b latency=64 link=no mingnt=64 multicast=yes port=twisted pair resources: irq:26 memory:fdf60000-fdf6ffff If I try to ifup eth1, then I get $ sudo ifup eth1 Ignoring unknown interface eth1=eth1. I figured that's what happens when there is no eth1 listed in /etc/network/interfaces. But when I add the configuration for eth1, I still can't ifup. $ sudo ifup eth1 RTNETLINK answers: File exists Failed to bring up eth1. I've also tried ifconfig eth1 up but without any result. For clarity, I have added a masked version of /etc/network/interfaces. I don't think it is the cause of the problem though. $ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 10.48.8.x netmask 255.255.255.y network 10.48.8.z broadcast 10.48.8.t gateway 10.48.8.u auto eth1 iface eth1 inet static address 193.190.253.x netmask 255.255.255.y network 193.190.253.z broadcast 193.190.253.t gateway 193.190.253.u I really need some help fixing this. It's driving me crazy. Thanks.

• iTunes and Hulu Playback Choppy and Slow?

  - by Bart Silverstrim

  Specs: Windows XP, latest updates 1.7 ghz Pentium 4 1 gig ram DirectX 9.0c NVIDIA GeForce FX 5200 with 256 meg RAM OpenGL 2.1 The story: Okay, I had an older system laying around that I figured I would try turning into a mini-media system to connect to our TV. I put together a lot of older parts, got it into working order, etc. and hooked it up and voila'...slower, but usable system that displayed to the TV. It could run some things decently. I put in iTunes, it played video okay. Not great, but okay. Played Hulu and since we have a 1Mb download rate, the minimum for their site, there were some choppy moments when watching their shows, but I found that (sadly) changing resolution to 800x600 seemed to help with the issue when running full screen. I downloaded the application called Boxee and installed it. It wouldn't run; apparently the video card in the system supported OpenGL 1.2, and needed at least 1.4. I bought a cheap card, the 5200, with four times the memory in it and support for OpenGL 2.1. Installed, everything seemed fine. iTunes seemed to run fine, the video driver (PNY video card) came with OpenGL 2.1, and Boxee finally ran. I then upgraded to the latest drivers for the video card and ran the DirectX updater from MS. After that, the OpenGL Extension Viewer wouldn't run. It just stayed as an icon in the task bar. Also, any and all videos in iTunes stuttered and went out of sync horribly. Unwatchable. I tried watching Hulu video in Boxee, and it displayed video like it was a series of stills in a very bad powerpoint. Playing straightforward audio-only came through fine, no stutters no hiccups. I tried system restore to roll back updates to pre-directX updates (I thought that seemed to be the time that triggered the weird behavior), no joy. I tried uninstalling and reinstalling the video drivers. I installed updated audio drivers (ensoniq audiopci), nothing helped. I finally wiped the drive last night and tried reinstalling everything and restoring my iTunes content via an import from a backup. Fresh install, no updater on the video card or directx. the problem was still there although I haven't tested Hulu, the iTunes player is still stuttering like crazy if I play video, fine if I play audio. I know the processor isn't high in heft, but with one gig of RAM and the fact that it seemed to do okay before I thought that the problem must be software related. Has anyone else run into this sort of issue and have a solution other than "buy a new computer"? What specs seem to work with video at the low end for you? Right now the system is of little use other than keeping my music library and iTunes apps synced with my iPod.
