• speeding up cvs pserver over WAN

  - by Aleksandar Ivanisevic

  I have a remote location with 5 developers that are using a CVS (pserver) repository in main office via WAN, but the bandwidth i have is only a couple of hundred kbps so CVS operations are fairly slow. Is there any way to speed this up? I can rsync over a local copy of the CVS root(s) every couple of minutes, so this can handle the updates, but obviously not the commits. Is there any way to say to CVS to update from one server, but push to another one? Any other ideas?

• Best alternatives to recover lost directories in FAT32 external hard drive?

  - by Sergio

  Hi: I have an 320 GB ADATA CH91 external hard drive. I guess it has some problems with the connector of the USB jack. The point is that in certain occasions it fails in write operations generating data losses. Right now I lost a directory with several GB's of very useful information. Since then I have not attempted to write to the disk any more. What tool would you recommend to recover the lost data? The disk is FAT32 formatted (only one partition) and I use both Linux and Windows. What filesystem format would you recommend to avoid future data losses? I currently only use this external hard drive in Linux so there are several available choices (FAT, NTFS, ext3, ext4, reiser, etc.). Regards, Sergio

• How do i tell if my drivers are up to date on Acer?

  - by joe

  Hoping some kind souls can help me out ? I got a blue screen the other day after trying to load sandboxie. So its obviously conflicting with something. I checked if my drivers were up to date on my acer aspire one AOD270 on this intel based site; http://www.drivermanager.com/en/down...tel&Logo=intel Its showing i have 2 drivers that need updating ; Intel NM10 Express chipset and the Realtek PCIE Cardreader. I have no idea whether to do the update via the Intel Driver update site or the Acer drivers download page? I then ran Bluescreenview and on the dump file its showing ; ''caused by driver'' igdkmd32.sys ''file description'' Intel (R) WDDM Kernel mode driver ''product name''Intel Graphics Accelerator Drivers for Windows 7(R) I bought the laptop here in SE Asia about a year ago. The ''HOT!! NEW download tool'' on the acer drivers site (below) doesnt seem to work and the info about removing and installing drivers is limited. Not sure what to trust on non acer/manufacturer sites. http://support.acer.com/us/en/produc...1&modelId=4040 I've located the igdkmd32.sys file inside the INTEL GRAPHICS MEDIA ACCELERATOR 3600 SERIES 8.14.8.1064. When i click on ''update driver'' in control panel it searches and says its up to date. In windows maintenance it says this intel had a problem, but no solution. For all i know my drivers could be up to date and its something else. Can anybody advise a dummy step by step the process i should follow ? I've never done this before. eg do i delete the old driver first and then download the new one.how much of a problem i could cause by downloading this type of thing wrongly? As yet i havent downloaded any drivers. I've asked on other forums but no luck as yet. Thanks for any help!

• how to cause linux system datetime to run faster than real world datetime?

  - by JamesThomasMoon1979

  Background I want to monitor a running linux system over several days. It's a custom gentoo build and with much custom software on board. This software has ongoing maintenance timers and cron scripts and other clock driven events. I need to verify these scheduled events are working. Problem Waiting for the system to step through daily and weekly activity is a long wait time. And modifying all clock-based timers on the system would be time consuming. Yet, I often want to test a system's end-to-end scheduled activities without waiting a week. Potential Solution Have the linux system under test appear to run through it's daily cycle of activity within just a few hours. My Question for Serverfault Is there a way to cause the system's time to run faster than real world time? My first thought is manipulating the ntp daemon to repeatedly and smoothly increment the clock . Any other ideas? And yes, I know this may have strange side affects. However, the system has no important or time critical interactions with systems outside of itself. And this may be a valuable testing technique.

• Linux's best filesystem to work with 10000's of files without overloading the system I/O

  - by mhambra

  Hi all. It is known that certain AMD64 Linuxes are subject of being unresponsive under heavy disk I/O (see Gentoo forums: AMD64 system slow/unresponsive during disk access (Part 2)), unfortunately have such one. I want to put /var/tmp/portage and /usr/portage trees to a separate partition, but what FS to choose for it? Requirements: * for journaling, performance is preffered over safe data read/write operations * optimized to read/write 10000 of small files Candidates: * ext2 without any journaling * BtrFS In Phoronix tests, BtrFS had demonstrated a good random access performance (fat better than XFS thereby it may be less CPU-aggressive). However, unpacking operation seems to be faster with XFS there, but it was tested that unpacking kernel tree to XFS makes my system to react slower for 51% disregard of any renice'd processes and/or schedulers. Why no ReiserFS? Google'd this (q: reiserfs ext2 cpu): 1 Apr 2006 ... Surprisingly, the ReiserFS and the XFS used significantly more CPU to remove file tree (86% and 65%) when other FS used about 15% (Ext3 and ... Is it same now?

• cmd.exe version comparison?

  - by Paul

  When using batch files or console applications on Windows servers the window in question can allow text to be hightlighted (marked) for copying and pasting. Doing this pauses the batch/application and it will only resume after the copy operation. Or this is what I thought to be true. Recently on a Windows 2003 R2 SP2 server I noted that whilst the scrolling was paused the operations were not. Does anyone know if my description in the 1st para is true for older windows is not true for Windows 2003 R2 SP2 when it changed a full version comparison table for cmd.exe across different OS' ? Thanks for reading (Windows 2000 tag as that was the OS I used most before 2003 R2)

• PCI compliance - Setting BIND to no recursion, cURL can't access external sites

  - by Exit

  I was running a PCI scan and was following direction to change the BIND options from: // recursion no; allow-recursion { trusted;}; allow-notify { trusted;}; allow-transfer { trusted;}; to: recursion no; allow-recursion { none;}; allow-notify { trusted;}; allow-transfer { none;}; The end result was that cURL operations stopped being able to access external sites. I realize that not everything will be 100% for PCI compliance, but can someone explain if there is a way to balance this for both PCI compliance and function?

• How reliable are Compact Flash drives

  - by bakytn

  For example, USB drives have read/write limits. and they are considered as unreliable and not durable for daily use over many years. My question is, however, about Compact Flash drives. AFAIK they are built almost in the same way as USB flash drives. I was going to use one Compact Flash drive for daily usage and install a lightweight operating system to it (Linux). What kind of limitations do they have? Read/write operations? Just a time? something else? Thank you!

• I flashed my DS4700 with a 7 series firmware, now my DS4300 cannot read the disks I moved to that lo

  - by Daniel Hoeving

  In preparation for adding a number of 1Tb SATA disks to our DS4700 I flashed the controller firmware from a 6 series (which only supports up to 2Tb logical drives) to a 7 series (which supports larger than 2Tb logical drives). Attached to this DS4700 was a EXP710 expansion drawer that we had planned to migrate out to our co-location to allieviate the storage issues we were having there. Unfortunately these two projects were planned in isolation to one another so I was at the time unaware of the issue that this would cause. Prior to migrating the drawer I was reading the "IBM TotalStorage DS4000 EXP700 and EXP710 Storage Expansion EnclosuresInstallation, User’s, and Maintenance Guide" and discovered this: Controller firmware 6.xx or earlier has a different metadata (DACstore) data structure than controller firmware 7.xx.xx.xx. Metadata consists of the array and logical drive configuration data. These two metadata data structures are not interchangeable. When powered up and in Optimal state, the storage subsystem with controller firmware level 7.xx.xx.xx can convert the metadata from the drives configured in storage subsystems with controller firmware level 6.xx or earlier to controller firmware level 7.xx.xx.xx metadata data structure. However, the storage subsystem with controller firmware level 6.xx or earlier cannot read the metadata from the drives configured in storage subsystems with controller firmware level 7.xx.xx.xx or later. I had assumed that if I deleted the logical drives and array information on the EXP710 prior to migrating it to the DS4300 (6.60.22 firmware) this would satisfy the above, unfortunately I was wrong. So my question is a) Is it possible to restore the DAC information to its factory settings, b) What tool(s) would I use to accomplish this, or c) is this a lost cause? Daniel.

• To Delete a tape from the ACSLSlibrary

  - by Senthil Kumar

  Hi Anyone there can help me out for an issue as below: There was a stuck tape in the drive and so the stuck tape was removed, but i need to logically delete the tape entry from NB, so that the same media can be inserted back for operations. Netback thinks that the tape is still in that location, hence it should be removed so that the entry is not there and NB does not recognise that the tape in that location, so the same tape can be taken in through inventory. The NB used is NB5.1 Any command to delete this entry, this is a clustered based Environment (Active/Passive), and we use a ACSLS library (Physical) as well a Switch-SN6000(Logical) Kindly help me out as when we tried to delete the media from GUI it said- Could not delete- Cannot delete assigned volume (92).

• Solaris SMF to Upstart on RHEL6

  - by aaa90210

  I am planning a migration from Solaris/x86 to RHEL6. Part of this migration will be migrating services from SMF to the RHEL6 equivalent, which appears to be upstart. While init.d scripts still seem to be supported, I want to take advantage of a more sophisticated init daemon, especially for features like job supervision (restarting etc). I would like to gather some thoughts on a few points: 1) Is upstart an adequate job supervisor, i.e. does it preclude the need for stand-alone managers like daemontools/supervise? 2) Upstart scripts seem very bare-bones compared to a typical init.d script. If I was porting an init.d script to Upstart, is it OK to just "exec /etc/init.d/myjob start"? This include RHEL installed programs like httpd. 3) Does upstart do anything is regards to pid files, and what are it's expectations in regards to the forking model of the process? 4) Are there any straightforward guides to the process management aspect of Upstart...and by that I mean the conditions around controlling restarting? e.g. how many times to restart the process before it goes into a maintenance state, or to ignore errors/core dumps in child processes of the supervised process. Any other relevant ideas or guides would be appreciated. TIA

• Re-deploy Reports on SCOM Management Packs

  - by Gabriel Guimarães

  I've migrated Reporting Services on a SCOM 2007 R2 install, and noticed that the reports have not being copied. I can create a new report, but the ones I've had because of the management packs are gone. I've tried re-applying the Management Packs however it doesn't re-deploy them and when I try to access for example: Monitoring - Microsoft Windows Print Server - Microsoft Windows Server 2000 and 2003 Print Services - State View - select any item and click Alerts on the right menu. I get the following error: Date: 12/24/2010 12:40:35 PM Application: System Center Operations Manager 2007 R2 Application Version: 6.1.7221.0 Severity: Error Message: Cannot initialize report.

• Use Web Browser (Google Chrome or Firefox) to Open Web Sites from a List in File

  - by MMA

  I have a (text) file containing a list of web site addresses. I know that I can open the file in an editor and then copy-paste the addresses to the browser address bar. That means, if I have ten addresses in that file, I will need ten copy-paste operations, which must be tedious. But is there a way to ask the browser (preferably Google Chrome or Firefox) to open all of them in one go in different tabs? I am using Ubuntu, if that is related in any way to the solution you provide.

• PS/2 to USB adapter doesn't work with Model M keyboard

  - by mickburkejnr

  I bought a server about 3 months ago from a friend, and I have only had time to tinker with it in the last week. I noticed that this server doesn't have any PS/2 ports, which meant configuring it was near impossible. I don't have any USB keyboards in the house, I only have an IBM Model M keyboard (built 1994) and another IBM keyboard that was built circa 2001. Both of them have PS/2 connections. I bought an adapter off eBay, and when I used it with the Model M keyboard the three lights on the keyboard flashed for a split second, but then the keyboard is then unresponsive. I can bash away at the keys for ages and nothing will happen. The same applies to the later built IBM keyboard. What could I do to make the adapter work? I am getting the loan of a USB keyboard in two weeks time, but I'd like a more permanent solution without having to rely on getting the loan of a keyboard every time I have to perform maintenance on the server. And as I already have two keyboards which work fine and I like using, I don't really want to have to buy another keyboard just for use on the server.

• Plesk file permissions - Apache/PHP conflicting with user accounts.

  - by hfidgen

  Hiya, I'm building a Drupal site which performs various automatic disk operations using the apache user (id=40). The problem is that the site was set up on a subdomain belonging to user ID 10001 (ie my main FTP account) so the filesystem belongs to that user ID. So I keep getting errors like this: warning: move_uploaded_file() [function.move-uploaded-file]: SAFE MODE Restriction in effect. The script whose uid is 10001 is not allowed to access /var/www/vhosts/domain.com/httpdocs/sites/default/files/images/user owned by uid 48 in /var/www/vhosts/domain.com/httpdocs/includes/file.inc on line 579. I've tried changing the apache group in httpd.conf to apache:psacln, psacln being the default group for all web users but that's not helped. The situation now is: ..../files/images/ = 777 and chown = ftplogin:psacln ..../files/images/user = 775 and chown = apache:psacln ..../files/tmp = 777 and chown = ftplogin:psacln So apparently uid 40 and 10001 both have permissions to write to any of the 3 directories involved, but still can't. Am i missing something here? Can anyone help? Thanks!

• How many times can data be read from a USB flash drive?

  - by John

  While I am aware that performing writes on a USB flash drive degrades the life expectancy of the device. I have heard the quantity of writes is anywhere from 100 thousand to 10 million, but I have not heard about number of read operations. Does reading from the device count toward this total? I am interested in writing only once to a flash drive and setting it to read-only. Then reading files from the device a thousand or more times per day, but am wondering if (at say 1,000 reads per day), the flash drive will need to be replaced within 100 days (assuming a 100,000 r/w cycle lifetime)?

• OSX Server 10.5 - Cannot log into Workgroup Manager - diradmin password is correct

  - by Mister IT Guru

  I've got a setup where I am trying to rescue a broken AD. We can no longer authenticate on the Workgroup manager, with passwords being rejected all the time - even though it is correct. I can connect using the workgroup manager on another server and I get the user list as expected, but when I click the padlock to make changes, I get the following screen: The problem is, I know the password is correct, I just used it to connect to the server in the first place. I can log into the server using the local admin, and services such as AFP, VPN and SMB continue to serve users. I have about 300 or so users on this server, and I would very much like to avoid having a rebuild. As there is much configuration that has been done without my knowledge (it's a client machine), I'd like to attempt to fix it, and then create another server and migration OD off this broken machine, then decommission it "gently". Ultimately this would mean no disruption of services. What I'd like it some tips as to how to fix the problem with authenticating to make changes in the work group manager, and maintenance on open directory in general. Thanks

• Help replacing old Windows 2003 SBS DC with a Win2008 Standard Edition DC

  - by Chris

  Objective: Trying to replace a Windows 2003 SBS domain controller with a windows server 2008 Standard Edition Domain Controller. What I did: used ADPREP. Then all user accounts and OUs are successfully replicated into the 2008 server. I have also managed to transfer all the DC roles (operations master,schema,pdc) into the Server 2008. I have also used NETDOM QUERY FSMO . It displayed that all the roles transferred to the 2008 server. Problem: When I am trying to demote the windows 2003 SBS server using DCPROMO, the message is “No other Active Directory for this domain can be contacted”. I also tried shutting down the 2003 server. Users can login into the domain but they have trouble finding SHARED folders. Can someone help me find out what I did wrong ? Need a little push in the right direction here. Thank you very much ?

• Implications and benefits of removing NT AUTHORITY\SYSTEM from sysadmin role?

  - by Cade Roux

  Disclaimer: I am not a DBA. I am a database developer. A DBA just sent a report to our data stewards and is planning to remove the NT AUTHORITY\SYSTEM account from the sysadmin role on a bunch of servers. (The probably violate some audit report they received). I see a MSKB article that says not to do this. From what I can tell reading a variety of disparate information on the web, a bunch of special services/operations (Volume Copy, Full Text Indexing, MOM, Windows Update) use this account even when the SQL Server and Agent service etc are all running under dedicated accounts.

• What's the simplest configuration of SVN on a Windows Server to avoid plain text password storage?

  - by detly

  I have an SVN 1.6 server running on a Windows Server 2003 machine, served via CollabNet's svnserve running as a service (using the svn protocol). I would like to avoid storing passwords in plain text on the server. Unfortunately, the default configuration and SASL with DIGEST-MD5 both require plain text password storage. What is the simplest possible way to avoid storing passwords in plain text? My constraints are: Path-based access control to the SVN repository needs to be possible (currently I can use an authz file). As far as I know, this is more-or-less independent of the authentication method. Active directory is available, but it's not just domain-connected windows machines that need to authenticate: workgroup PCs, Linux PCs and software that uses PySVN to perform SVN operations all need to be able to access the repositories. Upgrading the SVN server is feasible, as is installing additional software.

• How to create a chained differencing disk of another differencing disk in Virtual Box?

  - by WooYek

  How to create a differencing disk (a chained one) from a disk that is already a differencing image? I would like to have: W2008 (base immutable) - W2008+SQL2008 (differencing, with SQL installed) --- This I can do. - W2008+SQL2008+SharePoint (chained differencing with Sharepoint installed on top of SQL2008) There's some info about it the manual: http://www.virtualbox.org/manual/ch05.html#diffimages Differencing images can be chained. If another differencing image is created for a virtual disk that already has a differencing image, then it becomes a "grandchild" of the original parent. The first differencing image then becomes read-only as well, and write operations only go to the second-level differencing image. When reading from the virtual disk, VirtualBox needs to look into the second differencing image first, then into the first if the sector was not found, and then into the original image.* I don't get it...

• Does multiple files in SQL Server when using RAID help reduce conflicts in growth and file-locking?

  - by Dr Giles M

  I've been reading around and get the impression that if you are using RAID then using multiple SQL Server files within a filegroup won't yeild any more improvements, and the benefits are purely administrative (if you started to run out of space or wanted to partition off data into managable chunks for backups/balancing the data around your big server room). However, being a reasonably savvy software person, it's not unthinkable to hypothesise that, even for smaller databases that SQL Server will perform growth and locking operations (for writes) on a LOGICAL file basis, so even if you are using RAID, it seems to make sense to have multiple files in a file group to balance I/O, or does the time taken to reconstruct the data from distributed filegroups outweigh the benefits of reduced locking? I'm also aware that the behaviour and benefits may be different for tables/indeces/log. Is there a good site that distinguishes the benefits of multiple files when RAID is already in place?

• python: what are efficient techniques to deal with deeply nested data in a flexible manner?

  - by AlexandreS

  My question is not about a specific code snippet but more general, so please bear with me: How should I organize the data I'm analyzing, and which tools should I use to manage it? I'm using python and numpy to analyse data. Because the python documentation indicates that dictionaries are very optimized in python, and also due to the fact that the data itself is very structured, I stored it in a deeply nested dictionary. Here is a skeleton of the dictionary: the position in the hierarchy defines the nature of the element, and each new line defines the contents of a key in the precedent level: [AS091209M02] [AS091209M01] [AS090901M06] ... [100113] [100211] [100128] [100121] [R16] [R17] [R03] [R15] [R05] [R04] [R07] ... [1263399103] ... [ImageSize] [FilePath] [Trials] [Depth] [Frames] [Responses] ... [N01] [N04] ... [Sequential] [Randomized] [Ch1] [Ch2] Edit: To explain a bit better my data set: [individual] ex: [AS091209M02] [imaging session (date string)] ex: [100113] [Region imaged] ex: [R16] [timestamp of file] ex [1263399103] [properties of file] ex: [Responses] [regions of interest in image ] ex [N01] [format of data] ex [Sequential] [channel of acquisition: this key indexes an array of values] ex [Ch1] The type of operations I perform is for instance to compute properties of the arrays (listed under Ch1, Ch2), pick up arrays to make a new collection, for instance analyze responses of N01 from region 16 (R16) of a given individual at different time points, etc. This structure works well for me and is very fast, as promised. I can analyze the full data set pretty quickly (and the dictionary is far too small to fill up my computer's ram : half a gig). My problem comes from the cumbersome manner in which I need to program the operations of the dictionary. I often have stretches of code that go like this: for mk in dic.keys(): for rgk in dic[mk].keys(): for nk in dic[mk][rgk].keys(): for ik in dic[mk][rgk][nk].keys(): for ek in dic[mk][rgk][nk][ik].keys(): #do something which is ugly, cumbersome, non reusable, and brittle (need to recode it for any variant of the dictionary). I tried using recursive functions, but apart from the simplest applications, I ran into some very nasty bugs and bizarre behaviors that caused a big waste of time (it does not help that I don't manage to debug with pdb in ipython when I'm dealing with deeply nested recursive functions). In the end the only recursive function I use regularly is the following: def dicExplorer(dic, depth = -1, stp = 0): '''prints the hierarchy of a dictionary. if depth not specified, will explore all the dictionary ''' if depth - stp == 0: return try : list_keys = dic.keys() except AttributeError: return stp += 1 for key in list_keys: else: print '+%s> [\'%s\']' %(stp * '---', key) dicExplorer(dic[key], depth, stp) I know I'm doing this wrong, because my code is long, noodly and non-reusable. I need to either use better techniques to flexibly manipulate the dictionaries, or to put the data in some database format (sqlite?). My problem is that since I'm (badly) self-taught in regards to programming, I lack practical experience and background knowledge to appreciate the options available. I'm ready to learn new tools (SQL, object oriented programming), whatever it takes to get the job done, but I am reluctant to invest my time and efforts into something that will be a dead end for my needs. So what are your suggestions to tackle this issue, and be able to code my tools in a more brief, flexible and re-usable manner?
