• Postfix issues sending mail to addresses under domain located on server

  - by iamthewit

  I recently installed virtualmin on my nice shiny new rackspace cloud. Everything went seemlessly but I've been having some issues getting emails to send properly. The problem seems to be that the server can not send mail to email addresses where the domain is owned by my server. For example, on my server I run multiple virtual domains, lets call this one test.com. When I run the mail command from shell (mail [email protected]) I get the following back from my maillog: Oct 6 14:55:18 test postfix/pickup[8737]: DC1131612CC: uid=0 from= Oct 6 14:55:18 test postfix/cleanup[8769]: DC1131612CC: [email protected] Oct 6 14:55:18 test postfix/qmgr[8738]: DC1131612CC: [email protected], size=353, nrcpt=1 (queue active) Oct 6 14:55:18 test postfix/error[8771]: DC1131612CC: [email protected], relay=none, delay=0, delays=0/0/0/0, dsn=5.0.0, status=bounced (User unknown in virtual alias table) Oct 6 14:55:18 test postfix/cleanup[8769]: DD07D1612D1: [email protected] Oct 6 14:55:18 test postfix/bounce[8772]: DC1131612CC: sender non-delivery notification: DD07D1612D1 Oct 6 14:55:18 test postfix/qmgr[8738]: DD07D1612D1: from=<, size=2268, nrcpt=1 (queue active) Oct 6 14:55:18 test postfix/qmgr[8738]: DC1131612CC: removed Oct 6 14:55:18 test postfix/local[8773]: DD07D1612D1: [email protected], relay=local, delay=0.03, delays=0/0/0/0.03, dsn=2.0.0, status=sent (delivered to command: /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME) Oct 6 14:55:18 test postfix/qmgr[8738]: DD07D1612D1: removed when I run mail [email protected] the message is sent and received perfectly fine. I'm a bit of a noob when it comes to servers, but I pick things up fairly quickly, so please excuse any incorrect terminology and my general noobiness. Any help would be greatly appreciated, I've been googling for quite a while but I haven't found a solution yet, I'll add a copy of my main.cf file in a response below cheers guys here is the reformatted postconf, do you want the reformatted main.cf file too, or is this enough? alias_database = hash:/etc/postfix/aliases alias_maps = hash:/etc/postfix/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 home_mailbox = Maildir/ html_directory = no mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man myhostname = server.test.com newaliases_path = /usr/bin/newaliases.postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES sample_directory = /usr/share/doc/postfix-2.3.3/samples sender_bcc_maps = hash:/etc/postfix/bcc sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous unknown_local_recipient_reject_code = 550 virtual_alias_maps = hash:/etc/postfix/virtual

• Multiple OS's and GRUB chainloading

  - by Kent

  Hi, I want to have multiple OS installations and I have been advised that chain loading using GRUB is a good way to handle this. I have looked at tutorials on the web but I still have some questions before I can start. I want: Windows XP: 20 GB. For running some school stuff and a game which does not work through WINE. Xubuntu 9.04: 85 GB. My main OS. Another Linux distribution: 15 GB . For experimenting and trying Linux distributions out. I will: Wipe and install various distributions quite often on the 15 Use dd to make a copy of my Windows partition after installing it and getting things to work as I like. My experience is that Windows needs to be re-installed maybe once per year to not get bloated and slow. I have been told: To use GRUB chain loading. It will make it easier when kernel upgrades are made in the Linux distributions, as they modify the GRUB boot-menu. To my understanding I need to: (I might very well be mistaken) Install Windows first. Then install Xubuntu and let it write over the MBR with GRUB (I guess this is the default). Get the GRUB on the MBR start Windows XP if I want to (it's done by default), start Xubuntu using the kernel of my choice or defer execution to the boot sector of my other Linux distribution. The actual chain loading will only occur when I want to start my experimental install of Linux. I wonder: Is step 3 above correct and a good way to handle this? Is it also a good way to use chain-loading for both Xubuntu and my experimental Linux installation? How do I get a Linux distribution to install the boot loader it comes with to the boot sector of its partition and not to the MBR? If I can't get it to not touch the MBR. Then I could make a backup of the MBR using dd and then write it back after installing my experimental Linux installation. But then, how would I get the boot loader (lets say GRUB) into the boot sector of the experimental Linux installation? How would it work if said Linux installation gets a new kernel update and needs to update the GRUB menu?

• 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?

• Is there a Distributed SAN/Storage System out there?

  - by Joel Coel

  Like many other places, we ask our users not to save files to their local machines. Instead, we encourage that they be put on a file server so that others (with appropriate permissions) can use them and that the files are backed up properly. The result of this is that most users have large hard drives that are sitting mainly empty. It's 2010 now. Surely there is a system out there that lets you turn that empty space into a virtual SAN or document library? What I envision is a client program that is pushed out to users' PCs that coordinates with a central server. The server looks to users just like a normal file server, but instead of keeping entire file contents it merely keeps a record of where those files can be found among various user PCs. It then coordinates with the right clients to serve up file requests. The client software would be able to respond to such requests directly, as well as be smart enough to cache recent files locally. For redundancy the server could make sure files are copied to multiple PCs, perhaps allowing you to define groups in different locations so that an instance of the entire repository lives in each group to protect against a disaster in one building taking down everything else. Obviously you wouldn't point your database server here, but for simpler things I see several advantages: Files can often be transferred from a nearer machine. Disk space grows automatically as your company does. Should ultimately be cheaper, as you don't need to keep a separate set of disks I can see a few downsides as well: Occasional degradation of user pc performance, if the machine has to serve or accept a large file transfer during a busy period. Writes have to be propogated around the network several times (though I suspect this isn't really much of a problem, as reading happens in most places more than writing) Still need a way to send a complete copy of the data offsite occasionally, and this would make it very hard to do differentials Think of this like a cloud storage system that lives entirely within your corporate LAN and makes use of your existing user equipment. Our old main file server is due for retirement in about 2 years, and I'm looking into replacing it with a small SAN. I'm thinking something like this would be a better fit. As a school, we have a couple computer labs I can leave running that would be perfect for adding a little extra redundancy to the system. Unfortunately, the closest thing I can find is Dienst, and it's just a paper that dates back to 1994. Am I just using the wrong buzzwords in my searches, or does this really not exist? If not, is there a big downside that I'm missing?

• $PATH is driving me nuts

  - by Chris4d

  OK, apologies if this is something dumb, but I'm running out of ideas. Goal: prepend /usr/local/bin to $PATH Problem: $PATH won't do what I want or expect How I got here: I want to start learning to program, so I'm getting comfortable messing around under the hood, but don't have a lot of experience. I installed the fish shell (because it's friendly!) using homebrew and set it as my default shell (under system prefs>users & groups>advanced). At some point, I ran brew doctor to see if my installs were all kosher, and it suggested I move /usr/local/bin to the front of $PATH so that I could use my installation of git rather than the system copy. Fine - but between path_helper and fish, something was happening to $PATH that was out of my control, and I could never get the paths arranged in the right way. Environment: OSX 10.8.2, upgraded from 10.7ish, with xcode and devtools installed, plus x11, homebrew, and fish More info: I've set my user's default shell back to bash, and tried a variety of shells thru terminal.app - bash, fish, sh. I moved /usr/local/bin to the top of /etc/paths but it didn't change anything. I looked thru the various config.fish files and commented out stuff that might mess with $PATH, didn't help. I have the following files in /etc/paths.d/: ./10-homebrew containing /usr/local/bin ./20-fish containing /usr/local/Cellar/fish/1.23.1/bin ./40-XQuartz containing /opt/X11/bin I added set +x to my profile and when I start terminal.app I get: Last login: Mon Oct 1 13:31:06 on ttys000 + '[' -x /usr/libexec/path_helper ']' + eval '/usr/libexec/path_helper -s' ++ /usr/libexec/path_helper -s PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/Cellar/fish/1.23.1/bin:/opt/X11/bin"; export PATH; + '[' /bin/bash '!=' no ']' + '[' -r /etc/bashrc ']' + . /etc/bashrc ++ '[' -z '\s-\v\$ ' ']' ++ PS1='\h:\W \u\$ ' ++ shopt -s checkwinsize ++ '[' Apple_Terminal == Apple_Terminal ']' ++ '[' -z '' ']' ++ PROMPT_COMMAND='update_terminal_cwd; ' ++ update_terminal_cwd ++ local 'SEARCH= ' ++ local REPLACE=%20 ++ local PWD_URL=file://Chriss-iMac.local/Users/c4 ++ printf '\e]7;%s\a' file://Chriss-iMac.local/Users/c4 Chriss-iMac:~ c4$ So it looks like path_helper runs, but then running echo $PATH nets me /usr/bin:/bin:/usr/sbin:/sbin. So, it looks like path_helper isn't even doing what it's supposed to anymore? I'm sure there is some well-defined behavior here that I don't understand, or I borked something while trying to fix it. Please help!

• What Sort of Server Setup Am I Likely to Need? - School A/V streaming

  - by DeathMagus

  My prior experience with servers has generally been limited to home file-sharing servers, low-traffic web-servers, and the like. This leaves me with the technical knowledge of how to set up a system, but little experience in terms of scaling said system. My current project, however, has me as the technical lead in setting up a school for online audio and video streaming. The difficulty I'm running into is that I don't quite have the experience to guess what they'll need, and they don't have the experience to tell me - so I've tried to ask as many pertinent questions about what they want to do with their server, and here's what I found out: About 1000 simultaneous users, and hoping to expand (possibly significantly) Both video and audio streaming, at obviously the highest quality possible Support for both live and playlist-based streaming. Probably only one channel, but as it's an educational opportunity, I imagine letting them have a few more wouldn't hurt. No word on whether they're locked into Windows or whether Linux is acceptable. Approximate budget - $7000. It may actually be about $2k less than this, because of a mishap with another technology firm (they ordered a $7000 DV tape deck for some reason, and now the company wants them to pay a 30% restocking fee). The tentative decisions I've already made: I'm planning on using Icecast 2 for my streaming server, fed by VLC Shoutcast encoding. Since the school already has a DMZ set up, I plan on placing the Icecast server in there, and feeding it through their intranet from a simple workstation computer in their studios. This system isn't in any way mission critical - it's an education tool (they're a media magnet school), so I figure redundancy is not worthwhile to them from a cost:benefit perspective. What I don't know is this: How powerful of a server will I need? What is likely to be my major throttle - bandwidth? How can I mitigate that? Will I need anything special for the encoding workstation other than professional video and audio capture cards and a copy of VLC? Are there any other considerations that I'm simply missing? Thanks a lot for any help - if there's more information you need, let me know and I'll tell you all I can.

• Well....a ghost lives in my server...

  - by tsgiannis

  Hello to every body and greetings from Greece I have a rather unusual situation and i am running out of ideas. I have this old server (IBM x205 - P4 2.4Ghz,3xSCSI 36gb) and i was about a year ago i decided to use it as an additional domain controller,fax & file server...for this task i had a Delock 70154 SATA card along with 2x320 SATA II HDDs Everything was going super smoothly until about 3 weeks ago. I was on a trip and i was informermed when i got back that the server was found frozen...well i considered it was a glitch since a simple powerdown power up fixed everything.Again 2 weeks ago another freeze situation....it got suspicious but again power down power up everything was running.... Last again it frozen and when i power it up it came with a message that the Domain services could not start due to NTDS corruption....booting in safe mode revealed that there was an issue with the SATA Raid (degraded). After a lot of searching i degraded the server...cleaned Active Directory and pulled both HDDs out (one of these was really BAD ) and recovered my files (i had some problems with ho Delock handles the redudant HDD). Right now my server is vanilla simple...with only what the factory installed and here is where the fun begins. Everyday when i arrive at the office i find this particular machine dead..and i mean total dead...just a black screen and nothing else...the cpu fan is working ,the psu is working .keyboard and mouse are dead(they also lock my kvm) ...network is dead.... the machine is DEAD. I power it down forcilly ...i power it up and for the 8 hours i am in the office it works,either idling or running some kind of diagnostic...when i leave the office after some time..it maybe half an hour ...it maybe 4 hours the machine dies...at least this is the information the event log shows (" the previous shutdown at xx:xx:xx was unexpected) Well i must admit i am runnig out of ideas.... I have tried Memtest....nothing Passmark burn in test.....nothing Carefull study of the event log.....nothing Set Instead of restart..BSOD....nothing Power sceheme to sleep...all set to never. i know there are a lot of other tools that heavily stress a machine like occt but .... the machine is old...today i will give them a try nevertheless ..... One idea is to reformat it...but ... i really like to find what is causing this because i could get to a situation that everything is working for a while and kaboom...one day again is dying.. I really need a helping hand and every opinion / idea is well welcomed.... iknow the obvious solution is to never leave the office but....i have a life...sory server...:) P.S this situation with the machine dying some time after is going on for about one week...everyday i would set either the RAID to rebuild....or to copy/recover files and while everythig was working

• git, egit, submodules, and symlinks -- how should shared sub-projects be handled in eclipse?

  - by Autophil

  Here's the situation. I have a few git projects with a directory structure layed out more or less like this: simpleproj app www admin demo lib model orm view model user blah ... storeproj app www about mobile fbapp lib model orm view model user message cart product merchant Each directory in "lib" contains a separate project, either created in-house or forked, all of which use git for source control. So I figured I should make them submodules of my projects, right? Well, we've been moving toward eclipse + egit, because some of our windows guys not used to a CLI need something they can use without being scared of screwing things up. Anyway, the problem is, egit doesn't support submodules. So, my solution has been a rather crude one involving symlinks... lets say my directory structure on my dev box is generally layed out like this: ~/projects/ bigproj .git app lib model (- ~/lib/model/src/) orm (- ~/lib/orm/src/) neatproj .git app lib view (- ~/lib/view/src/) oldproj .git app lib orm (- ~/lib/orm/src/) ~/lib/ model .git src README.md orm .git src COPYING view .git src ...the symlinks link inside of directory with the git repo, so eclipse doesn't get confused, and everything sort of works. On my machine, I can update the libs from anywhere and all projects will be updated (needing to be committed again of course). Each project stores a separate copy of the contents of the symlinked directories within "lib" -- but only when staged from within eclipse. After committing from eclipse and moving back to the CLI, git sees that a bunch of files have been removed and a few symlinks have been created. Of course this is acceptable also, probably more so than keeping a separate history of the libs for each project... but eclipse and CLI git obviously need to be on the same page so tons of files aren't vanishing and reappearing. So this brings me to my question. I'd like to know how to either: get eclipse+egit to see the symlinks as symlinks if git will somehow handle them properly*, or get the CLI git to treat them as non-symlinks. Or, if there's a better way to do this, I'm all ears. Hope this all made sense! :D Note: tried to tag this as git-submodules, but was not allowed :( * should I make them relative or absolute? Either way it's a mess. Also will symlinks will work on windows? i know there's something similar but you need a 3rd party tool to manage them AFAIK, i doubt these would translate well.

• How can the Private Bytes of a process be significantly less than its effect on the system commit charge?

  - by bacar

  On a 64-bit Windows Server 2003, I can see using taskmgr or process explorer that the total commit charge is around 3.5GB, yet when I sum the Private Bytes consumed by each process (by running pslist -m and adding all values under the Priv column) the total comes in at 1.6GB. I know which process seems to be causing this (sqlservr.exe) as when I kill the process, the commit charge drops dramatically. However the process in question is consuming only ~220MB of Private Bytes yet killing the process drops the commit charge by ~1.6GB. How is this possible? How can the commit charge be so significantly greater than Private Bytes, which should represent the amount of committed memory? If some other factor contributes to the commit charge, what is that factor and how can I view its impact in process explorer? Note: I claim that I understand the difference between reserved and committed memory already: my investigations above relate specifically to Private Bytes which includes only committed memory and excludes reserved memory. the Virtual Size of the process in this case is over 4GB, but this should be irrelevant - Virtual Size in procexp represents reserved, not committed memory, and should not contribute to the commit charge. I'm particularly interested in generalised answers to this question: I'm assuming that if sqlservr.exe can behave in this way, that any process potentially could. Further Investigations I notice that pointing Sysinternals VMMap at this process reports a committed "Private Data" of 1.6GB despite Procexp's reported a Private Bytes of 220MB. This is particularly strange given that the documentation for this field in the "Windows® Sysinternals Administrator's Reference" states that: Private Data memory is memory that is allocated by VirtualAlloc and that is not further handled by the Heap Manager or the .NET runtime, or assigned to the Stack category... VMMap’s definition of “Private Data” is more granular than that of Process Explorer’s “private bytes.” Procexp’s “private bytes” includes all private committed memory belonging to the process. i.e. that VMMap's committed "Private Data" should be smaller than procexp's "Private Bytes". Also, after reading the 'Process committed memory' section of Mark Russinovich's excellent Pushing the Limits of Windows: Virtual Memory, he highlights two cases which won't show up in Private Bytes: File mapping views with copy-on-write semantics (however, according to VMMap there is no significant space allocated to Mapped Files). pagefile-backed virtual memory (however, I tried testlimit with the -l flag as suggested, and no significant memory is consumed by pagefile-backed sections)

• Can't find windows 2000 domain after PDC Change

  - by Mark A Kruger

  This is a windows 2000 domain issue. I had an old win2000 PDC that was beginning to fail. So, trying to be pre-emptive, I installed a new BDC, then "demoted" the old PDC and took it off the network. Now it appears that no member server can "find" the domain anymore. No logins work (for services or a RDP or anything). What I've tried (based on googling): Verified sysvol is shared on all servers. Used nslookup to verify that DC's are being found. netdiag /fix meta data cleanup routines. verified no firewall issues (port 389 etc) seizing all roles to new PDC (I did that as part of the original promotion). LMHOST file and Netbios settings. At the moment it seems like I can get the DC's returned but cannot contact them. I'm at a loss. My latest attempt was to remove a member server from the domain and try to "re-add" it. When I do that I get this message: The query was for the SRV record for _ldap._tcp.dc._msdcs.cfwebtools.com The following domain controllers were identified by the query: db-dev1.cfwebtools.com file-prod1.cfwebtools.com cfwt-pdc2.cfwebtools.com However no domain controllers could be contacted. It then goes on to ask if I've checked my A record and made sure they are running. Is there a way to force this domain to be seen? I also shared sysvol (or double checked it) and restarted the dfsr service. More information. I got looking at sysvol and found it was not shared on 2 of these servers. Only one of them (db-dev1) has a "good" or at least "populated" sys vol store. So I tried doing a "d2" recovery of my PDC against that good sysvol. But it never synchs - or at least it does not seem to synch. I'm guessing if I could get sysvol and netlogin to kick in and replicate that would fix my issue. I think these DC's aren't responding because they are waiting for replication which is broken somehow. Would taking down all the DC's except for db-dev1 fix the issue - at least temporarily? I know I can't just copy the sysvol stuff over to the other 2 can I?

• Data capture from other sheet into Summary sheet

  - by Hemant

  an Excel workbook which has Summary sheet, Pending and Master Sheet. My requirement is below and try to develop a Macro or VB logic for excel • I want to control this workbook from Summary sheet. o Generate Fault Summary – ? I have set logic but if doesn’t give warning if sheet name is exists , so need to add this logic . ? When we press the Fault Report Summary command button then it copy the master sheet with cell “A6” Name and will hide the Master sheet. Again when you select the another Month name then it will generate the sheet for that month name. o Generate Toll System Uptime ? When I select the sheet name and “Week” then Press the “Enter “Command button then it should get the result from that sheet number . Each sheet number has Month detail in B2 Cell. ? To calculate the Uptime formula for Week wise is • Week-01 = (1680-SUMIFS(L5:L23,B5:B23,"="&B2,B5:B23,"<="&(B2+6)))/1680 • Week-02 =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2+7),B5:B23,"<="&(B2+13)))/1680 • Week-03 =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2+14),B5:B23,"<="&(B2+20)))/1680 • Week-04 =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2+21),B5:B23,"<="&(B2+27)))/1680 • Month =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2),B5:B23,"<="&(DATE(YEAR(B2),1+MONTH(B2),1)-1)))/1680 ? Result should reflect in Summary sheet at B18 cell . o Pending Fault Report Summary ? When segregate the report on its status like which one is open or Close . It is open then it is Pending Fault Report and when it is Close status it means it is closed. ? If any fault which has OPEN status in all sheets(Jan-13,Feb-13,Mar-13….etc) then it should be come as well as in Pending Sheet which ascending date order. ? When it’s status is changed then it should be moved in that month sheet or nearby fault created date. It status is close then it should not be available in pending sheet as it’s status is Closed. ? Each fault has Reported date and we monitor all fault according reported date. ? When we press the Update Fault Report Summary command button then it should update as above logic. ? Some time we export the Pending fault report , so date calendar should be present in Start and End date to Choose the date. When we press the Export command line then it should export the Pending fault report and able to save in Excel,PDF.

• Windows 8 disk errors

  So yesterday, I forcibly restarted my Windows 8 PC. VMWare Workstation was having some trouble with the guest Linux Mint OS. It wasn't responding for some time, so I tried suspending it September 28th or perhaps even before. It wouldn't suspend -- I forgot what the window looked like, but all options in the power menu were disabled (i.e. "Shutdown," "Power Off," and options like that were all disabled). I eventually killed the VMWare application through Task Manager, though I was too lazy to hunt down the running virtual machine itself, and decided to kill it by just shutting down my PC entirely. The PC wouldn't shut down for quite some time after the monitor went blank, so I did a cold reset by holding the power button. I then powered it on again and Windows briefly gave me some message like "Search for KERNEL_STACK_INPAGE_ERROR." Windows then started diagnosing some problems and gave me the message, "Repairing disk errors. This might take over an hour to complete." That was yesterday night, and I went to sleep without waiting for it to finish. This morning, it said that the repair failed, and that the log was at C:\windows\system32\LogFiles\srt\srtTrail.txt (as I remember it -- I don't have the exact path I wrote down right now). It gave me some other options to troubleshoot, such as resetting Windows (files and settings still intact, but programs not installed through the app store will be erased). That didn't work (no error message given, I was just told it didn't work). I tried rebooting in safe mode, the same diagnosis process begins, except that this time it doesn't bother with the automatic repairs again. So I tried using the command prompt to try to see if my files are at least still there. I was on the X drive, and I couldn't cd to the C drive. I couldn't find my folder under Users (of course?), and couldn't find the srt folder under LogFiles either. I am not sure what to try next. I have backed up everything, but to the cloud, so if absolutely necessary I can start off with a fresh copy of Windows and restore all my data, though it would be a hassle. Any thoughts on what might be wrong or what I can try? My computer was purchased just this June, so the hard drive should still be pretty new.

• My VPS ubuntu server is very slow

  - by askmike

  I just installed a frech copy of Ubuntu 12.04 on my vps because my old installation was very slow, unfortunately this did not fix the problem. With slow I mean requests for my PHP websites take a long time, very slow (30 sec per request) to slow (3+ sec per request). When it's really bad SSH is also laggish. The websites are: askmike.org (pretty standard Wordpress) mvr.me (own PHP) slow? very slow: Here is a picture of loading a clean install of wordpress slow: here is a picture of loading a small PHP based website the vps The VPS has 256mb ram and an 25GB hdd. Besides serving the 2 small websites it isn't doing anything AFAIK. What have I installed Clean Ubuntu server 12.04 LAMP stack few things like git and nodejs (not using both) ossec (because I thought my server was getting hammered) munin What I already tried / done I installed munin so that I could watch io speed and such. The problem is that I don't know where to look for in the munin report. I checked logs and don't see anything strange (although I don't really know where to look for besides strange / repetitive errors and GET requests). I configured Apache MPM to: <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 40 MaxRequestsPerChild 0 </IfModule> (apache is using prefork, the default) Stats I copied the munin report as it appeared at 4:50 last night to a site hosted on a shared webhost. Note that tonight my mysql crashed somewhere after 1:00 (which is a new problem altogether), so therefor the graph for last night might look strange. Can anyone help me get my VPS up to normal speed? EDIT: Thanks for the replies. The VPS is 10 bucks a month and is from directvps.nl (Dutch host and I'm also dutch). I did two speed tests for disk IO: $ dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync 1073741824 bytes (1.1 GB) copied, 23.1506 s, 46.4 MB/s $ dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync 1073741824 bytes (1.1 GB) copied, 39.3796 s, 27.3 MB/s Anyway: how can I prove to my VPS host that it is to slow? I can understand a server being busy slowing a website down. But 5-30 sec loadtime for a normal PHP webpage?

• Troubleshooting Network Speeds -- The Age Old Inquiry

  - by John K

  I'm looking for help with what I'm sure is an age old question. I've found myself in a situation of yearning to understand network throughput more clearly, but I can't seem to find information that makes it "click" We have a few servers distributed geographically, running various versions of Windows. Assuming we always use one host (a desktop) as the source, when copying data from that host to other servers across the country, we see a high variance in speed. In some cases, we can copy data at 12MB/s consistently, in others, we're seeing 0.8 MB/s. It should be noted, after testing 8 destinations, we always seem to be at either 0.6-0.8MB/s or 11-12 MB/s. In the building we're primarily concerned with, we have an OC-3 connection to our ISP. I know there are a lot of variables at play, but I guess I was hoping the experts here could help answer a few basic questions to help bolster my understanding. 1.) For older machines, running Windows XP, server 2003, etc, with a 100Mbps Ethernet card and 72 ms typical latency, does 0.8 MB/s sound at all reasonable? Or do you think that slow enough to indicate a problem? 2.) The classic "mathematical fastest speed" of "throughput = TCP window / latency," is, in our case, calculated to 0.8 MB/s (64Kb / 72 ms). My understanding is that is an upper bounds; that you would never expect to reach (due to overhead) let alone surpass that speed. In some cases though, we're seeing speeds of 12.3 MB/s. There are Steelhead accelerators scattered around the network, could those account for such a higher transfer rate? 3.) It's been suggested that the use SMB vs. SMB2 could explain the differences in speed. Indeed, as expected, packet captures show both being used depending on the OS versions in play, as we would expect. I understand what determines SMB2 being used or not, but I'm curious to know what kind of performance gain you can expect with SMB2. My problem simply seems to be a lack of experience, and more importantly, perspective, in terms of what are and are not reasonable network speeds. Could anyone help impart come context/perspective?

• Slow WLAN file transfer between server and tablet

  - by user266985

  My file server is running Ubuntu 12.04 and I'm sharing files from it over samba. It is connected via gigabit ethernet. My desktop, running Windows 8.1, is also connected via gigabit ethernet. I can transfer files between the two and completely saturate that gigabit pipe. However, I just got a Surface Pro 2, and I'm trying to stream HD movies from my server to the device over WiFi. For some reason, I can't break much past 1.5MB/s transferring files over the network. I've tried streaming through XBMC and a standard file copy; no difference. To add the confusion, if I connect to my guest network and then use my VPN server (installed on the router) to access the file server, I get around 3.2MB/s. I've been running diagnostics to determine the root and I think I've found it but I have no idea what is causing it or how to fix it.

• Local dns for testing websites using mobile devices

  - by Morpheu5

  Hi. I have no idea where to start from so sorry in advance if this topic has already been discussed. I usually develop web sites using my laptop as a development server, and recently I needed to test a web site using various mobile devices that can connect via wifi. Having no real AP, I set up a ad-hoc network using my laptop's wireless card and the devices can correctly browse the Internet and access the laptop's web server. The setup is as follows: subnet: 192.168.1.0/24 gateway to the Internet (wired adsl router/modem): 192.168.1.1 laptop: 192.168.1.64 (eth0, wired if connected to the gateway) and 192.168.1.32 (eth1, wifi if somewhat bridged to eth0) mobile devices (same for all, I only use one of them at any time for simplicity): 192.168.1.11 with default gw 192.168.1.1 Now, if I open either 192.168.1.32 or 192.168.1.64 from the mobile devices, I correctly get the default host of my Apache configuration. However I usually work with virtual hosts for many practical reasons, one of which being Drupal's peculiar implementation of multi-sites. For those who don't know how this works, Drupal takes the request's hostname and searches into its sites/ subdirectories for an appropriate configuration file. So, for example, suppose I request www.example.com, then Drupal would search for a config file in the following directories: sites/www.example.com/ sites/example.com/ sites/com/ sites/default/ So I decided to adopt the following style of virtual hosts: if the website I'm working on will be accessible using www.example.com I set up a sites/www.example.com/ directory and create a virtual host for local.www.example.com so Drupal have no trouble finding it. I've been told this is suboptimal from a dns point of view since I'd have to create an authoritative entry for example.com and turn Bind on only when I'm supposed to access the local copy, which is weird. However, if this is the only path I can follow, I still have some problems with Bind's configuration, as I couldn't find any guide that tells me in a clear, noob-friendly way, how to set up such an entry. On the other hand, I was wondering if I could set up an authoritative entry for local, so I could access www.example.com.local and tell in some way (which I don't even know if this is possible) Apache to put www.example.com instead of www.example.com.local in the relevant environment variable. Anyway, I have a last problem, sort of: when I launch Bind in debug mode with high verbosity, and make 192.168.1.32 as the primary dns for the devices, the output doesn't say anything about requests being made from the devices to Bind, so I'm not even sure it comes into play. As you can see, I'm a complete noob at these matters, but I'm eager to learn, so any help/pointer will be appreciated.

• What needs updating when moving a bootable Windows 7 (or Vista) partition?

  - by SuperTempel

  When I move a bootable NTFS partition with Windows on it to a different block offset, what needs updating to make it bootable again? In particular, here's what I tried: I have a disk with several partitions, one of which is the NTFS partition with Windows on it, and the disk uses the plain old MBR block 0 for the partitions layout (no more than 4 partitions). Now I format and partition a new, larger, disk. There I make room for the NTFS partition and copy the contents from the old disk's NTFS Windows partition into. And I make the partition "active". However, when I try to boot from this disk, I get a "read error" message immediately and the booting stops, the exact text is: A disk read error occurred Press Ctrl+Alt+Del to restart I verified that both disks have the same boot sector code in block 0. It seems to me that something else might need updating. I guess that somewhere there's a absolute block reference that I need to update, probably pointing to the next level loader or to the NT kernel. Update: I found this article going quite into the depth of what I want to know. However, it says to modify boot.ini, but I have Windows 7 installed here, where such things appear to have changed: No boot.ini but a folder called System Volume Information with GUID and other data in it that sounds related to my problem. Going to keep digging... Update 2: Thanks to the terrible looking but very informative website by starman, I was able to figure out the first step: The NTFS boot sector has a field for "hidden" sectors. This feld has to contain the sector number of the boot sector. This solves the "read error" message. Now, however, I get a "BOOTMGR is missing" error instead. Looks like there's another place where a block number has to be adjusted, but I can't find anything in the code listing about this. I do find a lot of help sites suggesting Windows tools for fixing this "BOOTMGR is missing" problem, but none seem to know what goes on behind the scenes. Kind of like suggesting to re-install Windows when there's a little problem with it. At least, those fixes seem to work, mostly involving the Bcdedit and Bootrec tools. Now, who knows what they do, especially the latter, in regards to a moved partition? Update 3: After lots of trial-and-error attempts, I believe now that the solution lies in the BCD-Template registry file, residing usually inside \Windows\System32\config. If I get this updated using the "bcdboot" command, Windows starts up from it. I am now in the middle of figuring out what information this registry contains relevant to the above question. Any pointers to the contents of this registry are welcome. Update 4: Turns out that while the BCD-Template file gets rewritten and has different binary contents than its predecessor, the values inside do not change. So it must be something else that bcdboot.exe writes. I had previously already checked if it changes the first 32 boot blocks of the partition, but they appear to remain unchanged. Parititon map doesn't get changed, either. So what is it that bcdboot modifies besides the BCD registry? Any tips on how I can trace that? Are there low level tools that show me what files a program writes to? Update 5: The answer seems to be: c:\Boot\BCD is also changed, and that appears to be the key file for the boot manager's process. I'll investigate this later... Update 6: It seems to be an important detail that I had originally two partitions created when I installed Windows 7: A small partition of 204800 sectors which appears to be a bootstrap partition, followed by the actual, large, partition containing the Windows system (drive C:). When I tried to transfer this installation to a new, larger, disk, I had kept the same two partitions intact on the new drive, although they ended up at a different offset. This alone led to the "BOOTMGR is missing" message. Since then, I've used bcdboot.exe only on the Windows partition, which added the \Boot\BCD file on that partition. That file (and folder) did originally only exist on the smaller partition. Hence, this problem may be more complicated in my case as one partition (the boot strapper) referred to another partition (the one containing the OS), whereas other people may only have to deal with one partition containing both, and maybe there the solution is simpler. Update 7: Found one more detail: The \Boot\BCD file records the MBR's serial number. If that number doesn't match, the system won't boot. Next I'll test if there's also an absolute block reference stored in there.

• Can't recover hard drive

  - by BreezyChick89

  My drive got corrupt after a thunderstorm. It used to be 1 partition of 2.5tb but now it shows 2 partitions. It's weird because 300gig free space is about how much it had before corrupting, but it was part of the first partition. I tried $ sudo resize2fs -f /dev/sdb1 Resizing the filesystem on /dev/sdb1 to 536870911 (4k) blocks. resize2fs: Can't read an block bitmap while trying to resize /dev/sdb1 Please run 'e2fsck -fy /dev/sdb1' to fix the filesystem after the aborted resize operation. sudo e2fsck -f /dev/sdb1 e2fsck 1.42 (29-Nov-2011) The filesystem size (according to the superblock) is 610471680 blocks The physical size of the device is 536870911 blocks Either the superblock or the partition table is likely to be corrupt! Abort? n .... Error reading block 537395215 (Invalid argument) while reading inode and block bitmaps. Ignore error<y>? yes Force rewrite<y>? yes Error writing block 537395215 (Invalid argument) while reading inode and block bitmaps. Ignore error<y>? yes ... A lot of these. I can't use e2fsck -y because the first question aborts if I say "y". If I put a weight on the 'y' key it fails because none of the errors were really fixed. I asked this question before and tried using gparted but gparted fails because the first thing it does is: e2fsck -f -y -v /dev/sdb1 giving the same error. The disk status says healthy. There are no bad blocks. This is very frustrating because I can see the data in testdisk and it looks like it's all there. I already bought another 2.5tb drive and made a clone using dd. The next step if I can't fix this is to wipe that drive and just move the data with testdisk, but it seems certain folders will copy infinitely until the drive is full because of symlinks or errors so it's also a difficult option. sudo fdisk -l Disk /dev/sdb: 2500.5 GB, 2500495958016 bytes 255 heads, 63 sectors/track, 304001 cylinders, total 4883781168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0005da5e Device Boot Start End Blocks Id System /dev/sdb1 * 2048 4294969342 2147483647+ 83 Linux sudo badblocks -b 4096 -n -o badfile /dev/sdb 610471680 536870911 badfile is empty I also tried changing the superblock with "fsck -b" but all of them are the same.

• A Windows Update Prevented Live Discs From Working?

  - by user88311

  First off I'll state my system specs. Acer Aspire M1100 Windows Vista Home Basic 32bit OEM 2 Gigs of DDR2 ram 160Gig hard drive 2.7Ghz AMD Athlon 64 processor ATI Radeon X1250 Graphics card A few days ago my computer did automatic updates and updated windows defender to KB915597 (Definition 1.135.415.0), After which when shutting down and starting up I would receive BSOD with the information BUGCODE_USE_DRIVER and 0x000000FE (0x00000008, 0x00000006, 0x00000006, 0x877330000) upon where my computer would not start up with any USB devices plugged in and it always require me to run startup repair before it started. Upon when I first started it up and was able to fully boot windows, I had no use of the mouse so I was unable to install the fix that the windows solutions center brought up on my screen, so I restarted again and installed the fix hoping it would cease the problem, it did not. Upoon starting up after installing the fix and restarting I was confronted with the BSOD 0x000000FE (0x00000008, 0x00000006, 0x00000006, 0x83291000) at which I found the startup repair could not fix the problem and I restored, as I most like should have in the first place. After going through that I read that simply installing the latest defender version from the microsoft site had fixed this problem for others, so I did that, to find I still received the BSOD's. So in a attempt to find a fix to the problem I went to the microsoft answers site to try to find a way to fix the problem, there I was told to simply disable defender and reboot to see if that fixed the problem, upon doing this my computer would no longer even startup, when I boot normally I get to just when the loading screen finishes and then my computer restarts and when I run startup repair, it runs for about 15 seconds and then my computer restarts as well. I have tried running ubuntu live discs in order to simply access the drive and simply copy and paste the 2 month old physical backup I have of my C drive to the C drive, but whenever I run the live OS when it gets to the end of the load screen and is about to boot, the computer again restarts, yet if I put in a gparted disc, I am able to boot it fully, although it does not give me access to the file system just partition managing and when I attempt to access the internet through it, the computer once again restarts. So my question is, how could the update and what has happened prevent me from running the live OS's properly?

• Lenovo Windows 8 EFI restore from image

  - by anderhil

  First time here. I have bought e530 with windows 8 and the first hour of work with it i have a problem. I have ssd with windows 7 which i want to use with my new e530. I have made a sysprep of win 7 and installed ssd to the e530. The HDD which was inside e530 i want to use as second hdd instead of my DVD Drive. I connected this HDD through usb-to-sata adapter to copy some files from ssd to the hdd. Unfortunately it didn't see the file system on the HDD (but first time i have booted to it and first boot into Windows 8) I've made some mistakes and i corrupt the filesystem on the hdd. I tried bunch of tricks to recover the GPT, but it didn't work. I have managed to recover the Lenovo_Recovery partition to my ssd using recovery tools. And now I'm stuck, with this new things to me - EFI, GPT, etc i don't how this stuff works, and i have been trying to understand this for hours - but nothing seems to work. I want to restore the Windows 8 to the hdd, so it is there alive. What i have done so far: Formated the HDD I took the PBRALL file from the Lenovo_Recovery " convert gpt create partition Primary size=1000 ID=DE94BBA4-06D1-4D40-A16A-BFD50179D6AC gpt attributes=0x8000000000000001 assign letter=W format quick LABEL=WINRE_DRV create partition efi size=260 assign letter=s format quick fs=fat32 LABEL=SYSTEM_DRV create par msr size=128 create partition primary noerr assign letter=t format quick LABEL=Windows8_OS shrink desired=12197 create partition Primary ID=DE94BBA4-06D1-4D40-A16A-BFD50179D6AC gpt attributes=0x8000000000000001 assign letter=q format quick LABEL=Lenovo_Recovery " it recreated the partitions copied contents of SDRIVE.zip to SYSTEM_DRV partition copied contents of WDRIVE.zip to WINRE_DRV partition Copied restored Lenovo_Recovery back to Lenovo_Recovery partition So now I have 3 system partitions: SYSTE_DRV BOOT boot.sdi EFI BOOT bootx64.efi LenovoBT.efi Lenovo ... Microsoft ... WINRE_DRV\Recovery\WindowsRE\winre.wim Lenovo_Recovery (whic contains install.wim and bunch of other things) So i put back the HDD inside the laptop and tried to boot - but nothing works. It just doesn't boot to anything - no errors - nothing at all. When I choose this HDD manually for boot - just black screen blinks and that's all - it returns back to the devices boot menu. SYSTEM_DRV is EFI partition, so I don't understand why it doesn't boot, it has files needed inside. Can anybody tell me what should be done to make it boot to recovery console or smth like that? How to restore the Windows 8 from the Lenovo_Recovery install.wim image? As I understand I have all the files where they should be, but why it doesn't work? How to troubleshoot such things? Also, if somebody has good link where EFI booting process is explained in details that would be great. Cause i still don't understand how it knows what partition to boot?

• Windows Update and IE fail to connect, but Chrome fine?

  - by I Gottlieb

  Out of ideas on this one. (Running Windows Vista.) I have a program that accesses the internet to retrieve financial market data. One day it tells me that it can't log in -- timeout error. I check the documentation and it says must have a working copy of IE browser installed. I check IE (have IE9) and sure enough -- it just spins. No error message, not timeout, no 'try later' -- just spins -- as far as I can tell, indefinitely. Any page, any address. Even access to a localhost site just spins. Chrome works fine. So does another program I have that fetches market data. Windows 'diagnose and repair' says my internet connection is working fine. I tried uninstall/re-install of IE. Same spinning. I tried to install Windows Updates, and guess what? I can't. I comes up with error 80072efd; checked documentation for the error and it says I should check firewall blockage. Thing is, the only firewall I have is Windows Firewall, and obviously it wouldn't be blocking Windows Update. In contrast, Windows 'Help' in all programs has no problem accessing the Internet. I had a filter on the internet connection, and this was updated just prior to first appearance of the problem. But I uninstalled the filter entirely (official, with passwd from the company's service rep) -- and no difference. I'm guessing that a high level Windows network service file is corrupted -- used only by MS programs and their ilk, but how do I find it? I'd like to avoid having to do a clean install of Windows. Much obliged for any insight. IG Ramhound -- Thanks for reply. I'm familiar with virtual machines as in e.g. JVM or an emulator for an alternative architecture or (theoretical) Turing Machine equivalence. But I'm not familiar with the way you're using the term. Please clarify -- what one needs for this VM 'test' and why you expect it will provide an advantage of insight into the problem. And what sort of 'configuration issue' are you referring to? IG

• Migrating Split Access Database from one domain to another (not working, details in Q)

  - by Expo_Rob

  Some background: I'm a programmer, not a network administrator, who has been asked to migrate some accounting software (Integrated Office Accounting version 3.2) from an existing domain (OLD_NETWORK) to a new domain (NEW_NETWORK). No-body at the office knows how it works under the hood. It is a split Access 2000 database with the back-end shared and on a file server (which is also the DC) using mapped drives. The DC is NT Server 4 SP 6. The new server is server 2003. The two networks are running independently (ie: two computers on each desk). I have been able to get new computers set up on NEW_NETWORK and working with the IOA software just perfectly but for one problem: The company here uses other entirely separate databases which access the tables IOA maintains (specifically the 'customers' table) via links. To switch between these systems, you press F11 then File-Open the appropriate database and away you go (this is necessary to maintain the permissions that the IOA system uses to protect the customers table). The entire database is Access 2000, the links go to other Access databases, SQL-Server is not involved in any way, nor is a migration to SQL server likely. If I can't migrate anything over, everything will stay as it is, and the NEW_NETWORK computers will not be used. The problem: When I try and update these seperate databases (I shall call one "BANK_ACCOUNT", but the name does not matter), it says "this recordset cannot be updated". It also will sometimes not pull information out of the 'customers' table (ie: date_entered) when looking at a report of everyone who opened a bank account on a certain day (ie: today). I have tried: Giving 'everyone' full control via. shared directory permissions Giving 'everyone' full control on a file system level Checking the permissions within Access (everyone has full read/write on all tables) Copying the entire server contents from one file server to another (ie: xcopy everything) Copying the entire local client files from one computer to another, putting them in the exact same position in the file system, with the same permissons (or full control to 'everyone'). Running as an Administrator Taking one of the NEW_NETWORK computers, having it join OLD_NETWORK and run the software (direct copy from a working system with identical drive mappings), this did not work Weeping openly My Question: Is there anything else I can try? (sorry for this being so long)

• iPhone XMLParser help

  - by Brodie4598

  I am needing to parse an XML file for my app and I dont have any clue how to do it. I went through one XMLParser tutorial, and it worked fine but the XML file in the tutorial was very simple and my XML file is quite a bit more complex. here is a snippet of the xml file: <?xml version="1.0" encoding="UTF-8"?> <digital_tpp cycle="1003" from_edate="0901Z 03/11/10" to_edate="0901Z 04/08/10"> <state_code ID="AK" state_fullname="Alaska"> <city_name ID="ADAK ISLAND" volume="AK-1"> <airport_name ID="ADAK" military="N" apt_ident="ADK" icao_ident="PADK" alnum="1244"> <record> <chartseq>10100</chartseq> <chart_code>MIN</chart_code> <chart_name>TAKE-OFF MINIMUMS</chart_name> <useraction></useraction> <pdf_name>AKTO.PDF</pdf_name> <cn_flg>N</cn_flg> <cnsection></cnsection> <cnpage></cnpage> <bvsection>C</bvsection> <bvpage></bvpage> <procuid></procuid> <two_colored>N</two_colored> <civil> </civil> <faanfd15></faanfd15> <faanfd18></faanfd18> <copter></copter> </record> <record> <chartseq>10200</chartseq> <chart_code>MIN</chart_code> <chart_name>ALTERNATE MINIMUMS</chart_name> <useraction></useraction> <pdf_name>AKALT.PDF</pdf_name> <cn_flg>N</cn_flg> <cnsection></cnsection> <cnpage></cnpage> <bvsection>E</bvsection> <bvpage></bvpage> <procuid></procuid> <two_colored>N</two_colored> <civil> </civil> <faanfd15></faanfd15> <faanfd18></faanfd18> <copter></copter> </record> </airport_name> </city_name> </state_code> </digital_tpp> What I'm needing to do is search the XML file for the <...icao_ident> that the user specifies, then create a dictionary containing the <pdf_name> and <chart_name> for each <record> . I will then create a UI that displays the pdf files. Can someone direct me to a good tutorial or explanation of how XML parser works? Or if I'm going about this the wrong way I'd be open to suggestions too. (the XML file is about 8MB)

• A format for storing personal contacts in a database

  - by Gart

  I'm thinking of the best way to store personal contacts in a database for a business application. The traditional and straightforward approach would be to create a table with columns for each element, i.e. Name, Telephone Number, Job title, Address, etc... However, there are known industry standards for this kind of data, like for example vCard, or hCard, or vCard-RDF/XML or even Windows Contacts XML Schema. Utilizing an standard format would offer some benefits, like inter-operablilty with other systems. But how can I decide which method to use? The requirements are mainly to store the data. Search and ordering queries are highly unlikely but possible. The volume of the data is 100,000 records at maximum. My database engine supports native XML columns. I have been thinking to use some XML-based format to store the personal contacts. Then it will be possible to utilize XML indexes on this data, if searching and ordering is needed. Is this a good approach? Which contacts format and schema would you recommend for this? Edited after first answers Here is why I think the straightforward approach is bad. This is due to the nature of this kind of data - it is not that simple. The personal contacts it is not well-structured data, it may be called semi-structured. Each contact may have different data fields, maybe even such fields which I cannot anticipate. In my opinion, each piece of this data should be treated as important information, i.e. no piece of data could be discarded just because there was no relevant column in the database. If we took it further, assuming that no data may be lost, then we could create a big text column named Comment or Description or Other and put there everything which cannot be fitted well into table columns. But then again - the data would lose structure - this might be bad. If we wanted structured data then - according to the database design principles - the data should be decomposed into entities, and relations should be established between the entities. But this adds complexity - there are just too many entities, and lots of design desicions should be made, like "How do we store Address? Personal Name? Phone number? How do we encode home phone numbers and mobile phone numbers? How about other contact info?.." The relations between entities are complex and multiple, and each relation is a table in the database. Each relation needs to be documented in the design papers. That is a lot of work to do. But it is possible to avoid the complexity entirely - just document that the data is stored according to such and such standard schema, period. Then anybody who would be reading that document should easily understand what it was all about. Finally, this is all about using an industry standard. The standard is, hopefully, designed by some clever people who anticipated and described the structure of personal contacts information much better than I ever could. Why should we all reinvent the wheel?? It's much easier to use a standard schema. The problem is, there are just too many standards - it's not easy to decide which one to use!
