• User unable to delete folder / files "File in use by another user" Server 2003

  - by Az

  I am administering a standalone Windows 2003 Terminal Server with no domain membership. Occasionally (about once a week or so) a user will attempt to delete a sub-folder in a Shared folder and gets denied with "File in use by another user". I tried checking the shared folder snap-in and that folder is not open. She has full control and is the owner of the folder as well. I even checked in "Effective permissions" for some of the folders / files she cant delete and she truly has full control. I am able to delete the folder as Administrator with no problem. Another odd thing, she can delete the files IN the folder most of the time (this issue happens on both folders and files in the share). Sometimes merely waiting a day or two will allow her to delete the folder or files. I am curious as to why she gets the message that it is in use as creator/owner with full control yet I don't get it simply as a member of the Admin group. If anyone out there has any ideas I'd love to hear them! THANK YOU.

• Timeperiod Setting

  - by Alvin G. Matunog

  I am running Nagios 3.2.3 on CentOS 5.7 32bit and I have a bit of a problem scheduling timeperiods. Please help me. Objective, to stop monitoring during server restart (since the server will be restarted and will be restarted automatically because of updates and system backup). The restart is scheduled every 1st Sunday of every month. My monitoring runs 24x7 but during restarts I want to stop the monitoring and resume after 30 mins. So every 1st Sunday I want my schedule to be 00:00-11:30,12:00-24:00. This means that it will stop at 11:30 and resumes on 12:00nn. If I set this on every Sunday there is no problem. But if I set this time on every 1st Sundays, it stops at 11:30 but resumes on the next day (Monday) and not on 12:00nn Sunday. I don't know what I am missing. If I set on regular weekdays there is no problem. But on Offset weekdays (1st Sunday) it doesn`t work the way it should have. Here is my definition; define timeperiod{ name 1st_sunday timeperiod_name 1st_sunday alias No monitoring every 1st Sunday thursday 1 00:00-11:30,12:00-24:00 } define timeperiod{ timeperiod_name irregular alias regular checking use 1st_sunday sunday 08:30-22:00 monday 08:30-22:00 tuesday 08:30-22:00 wednesday 08:30-22:00 thursday 08:30-19:10,19:20-22:00 friday 08:30-22:00 saturday 08:30-22:00 } Can anyone help me? Please? Thank you.

• Is my "Generic" USB Flash Drive broken?

  - by Jesse J.

  So here is the situation. I find myself technological knowledgeable about many things ( I love to code, whether it's websites, C#, C++ or so on). However: My 2 toddlers (my wife actually) bought me a "Generic" 128 GB USB Storage Device (Usb Flash Drive) for Father's Day. I thought awesome at first..... WRONG! Nothing but problems with it. 3-4mb/s MAX transfer speed. I can bear with it. BUT! When I went to reformat my computer I transferred my save files from my games over to the stick and then the USB Stick managed to become corrupted. Not just a simple format would work either. It's screwed. I tried to use (Manually changed usb drive letter troubleshooting it to X) "chmod X: /X /F /R" with administrator rights, I did this after a long session to make it work with no errors (had to delete the log) and I finally recovered the files, however when I go to use it (transfer to or from) it transfers a couple kb to the stick or from it and then freezes, It says (Windows 7): Name: From: Folder (X:\File\Location) To: Folder C:\Users\Username\Desktop) Items Remaining: 0 (0 bytes) Speed: 0 bytes/second It does this forever... and ever... and ever... It transfered 3 files atleast, and then stopped. This is a new USB Stick bought from a "High" reputation company on eBay. Is the USB Stick screwed?

• How to verify that a physical volume is encrypted? (Ubuntu 10.04 w/ LUKS)

  - by Bob B.

  I am very new to LUKS. During installation, I tried to set up an encrypted physical volume so that everything underneath it would be encrypted. I chose "Use as: physical volume for encryption," the installation completed and I have a working environment. How can I verify that the PV is indeed encrypted? I was never prompted to provide a passphrase, so I most likely missed a step somewhere. At the end of the day, I'd like whole disk encryption if that's possible, so I don't have to worry about which parts of the file system are encrypted and which aren't. If I did miss something, do I have to start over and try again, or can it be done (relatively easily?) after the fact? I would prefer not to introduce more complexity by using TrueCrypt, etc. Environment details: The drives are md raid1. One volume group. A standard boot lv. An encrypted swap lv using a random key (which seems to be working fine). Thank you in advance for your help. This is very much a learn-as-I-go experience.

• Long running php script hangs/terminates on IIS 7.5

  - by Rich

  I'm a bit of nube when it comes to configuring IIS 7.5 and Php so apologies if this is a silly question but I've been wrestling with this for over half the day and need some fresh input. I have a php application running on IIS 7.5 , php 5.4 running as fastcgi. The application works absolutley fine with the exception that long running php scripts seem to hang; no 500 error they simply seem never complete and return the results to the browser. I've written a simple test script below to eliminate the possibility of programming error in the main app : <?php /* test timeout */ /*set_time_limit(110);*/ echo "Testing time out in seconds\n"; for ($i = 0; $i < 175; $i++) { echo $i." -- "; if(sleep(1)!=0) { echo "sleep failed script terminating"; break; } } ?> If I run the script beyond 175 seconds it hangs. Below that it will return the results to the browser. Here are the time out parameters that I've set for php and fastcgi. I've also played around setting these really low in order to get various time out errors and have succeeded which brings me to the conclusion that there's another setting that I'm missing .. perhaps. fastcgi activity timeout=800 Idle Timeout = 900 request Timeout 800 Php max_execution_time=700 Any solutions or pointers in the right direction would be very ... very welcome. Thanks

• Laptop freezing every few seconds, including screen + sound

  - by zenstealth

  Just a few days ago, my Windows 7 HP dv4170us (1.76Ghz CPU, 1GB Ram) laptop started to freeze every other second where everything on screen and and sound (such as a song playing in iTunes) would just freeze until I bash it violently (without actually breaking the laptop) or wait for a couple of more seconds. I think it started one night when I noticed that a USB mouse of mine stopped working, and it displayed random "Device was not recognized" errors. I just unplugged the mouse and ignored it. Skip forward to the next day, is started freezing, and as of today I can't get my computer to not keep freezing. I tried to backup my files onto an external hdd, but it almost corrupted the drive. I ran 4 complete virus scans using MSSE and MalwareBytes (both quick and full scans), and they all came up clean. In the Task manager, the CPU usage is on a constant max, and so is the RAM (if I have just a few apps running, I only have like 30Mb of free RAM left). Also, on the outside of my laptop, right above where the CPU is located, it's very, very hot. I suspect that something is wrong internally within inside of the computer, but I'm not sure. It also does the same thing when booted into Ubuntu.Does anyone know what could be wrong with it?

• Unusual HEAD requests to nonsense URLs from Chrome

  - by JeremyDWill

  I have noticed unusual traffic coming from my workstation the last couple of days. I am seeing HEAD requests sent to random character URLs, usually three or four within a second, and they appear to be coming from my Chrome browser. The requests repeat only three or four times a day, but I have not identified a particular pattern. The URL characters are different for each request. Here is an example of the request as recorded by Fiddler 2: HEAD http://xqwvykjfei/ HTTP/1.1 Host: xqwvykjfei Proxy-Connection: keep-alive Content-Length: 0 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.13 (KHTML, like Gecko) Chrome/9.0.597.98 Safari/534.13 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 The response to this request is as follows: HTTP/1.1 502 Fiddler - DNS Lookup Failed Content-Type: text/html Connection: close Timestamp: 08:15:45.283 Fiddler: DNS Lookup for xqwvykjfei failed. No such host is known I have been unable to find any information through Google searches related to this issue. I do not remember seeing this kind of traffic before late last week, but it may be that I just missed it before. The one modification I made to my system last week that was unusual was adding the Delicious add-in/extension to both IE and Chrome. I have since removed both of these, but am still seeing the traffic. I have run virus scan (Trend Micro) and HiJackThis looking for malicious code, but I have not found any. I would appreciate any help tracking down the source of the requests, so I can determine if they are benign, or indicative of a bigger problem. Thanks.

• The Web Hosting Connundrum for "not quite" developers

  - by saltcod

  Hey all, Apologies if this post feels like its been covered elsewhere, but I don't think it has. I've been down a winding web hosting road. To date, I've tried: Joyent, Media Temple, Bluehost, Hostgator, and finally Linode. The reason for switching are likely obvious to everyone: speed. With the exception of the lightening fast Linode, all of the shared hosts are absolutely sloooow. What do do when you're not really a "developer" While I'v grown addicted to the speed of Linode, I really don't feel like its where I should be. I have this nagging feeling in the back of my mind that one of these days (likely soon), I'm going to run into something that i won't be able to figure out and i'll have days worth of downtime. Just the other day, for example, I realized that one of my domains wasn't sending emails. After 4(!) hours looking into the problem, I still can't get sendmail or postfix to work. Four hours!! I want to be a Drupal expert, not a Ubuntu expert That's really the heart of my problem: I spend way too much time learning Ubuntu's ins-and-outs, and not nearly enough time working on Drupal. So here goes: Is there a web host out there anywhere that offers the speed of Linode, but will let me focus on Drupal instead of sys-admin-ing? Thanks! [ I know, I know. There are going to be lots of people who read this saying - "just learn Ubuntu like a real developer". And I get that. I do. But when I work full-time and try and develop some of these sites in my evenings and weekends, I'm really feeling like the sys-admin stuff gets in the way.

• Giving the root user priority to maintain Debian (while server collapsing under heavy load)

  - by Saix

  Is there any way to setup Debian to prioritize any or specific root's activity before every other? For instance, several times per year something gets wrong (usually man's fault by overstressing apache/mysql) and system gets unresponsive under heavy load like 200 (8-core cpu). I know there are limits for php scripts to run then kill, but that's not the way because this limit has to be at least 45 minutes long. The problem is, until I'm able to login via SSH and let apache/mysql restart under this server stress, it nearly hits these 45 minutes anyway. Also hardware restart causing usually to run fsck at boot time on all harddrives since it's usually pretty long the box haven't been restarted. I was told it's really not good idea disabling fsck but then again, it takes more then hour to complete. What is the fastest way to restart apache/mysql? Is there any way to give ssh users or root user higher priority so the logging in and completing these restarts (rather stops though) commands wouldn't take so long? One comes to my mind.. use NICE for apache/mysql but no way. I can't risk limiting those two vital apps 24/7 or could I? I'm a little bit scared if any other system process wouldn't slow the pages down too much. Any backup process, swap (if any) etc. There is pretty heavy PHP framework with 20k visits a day, so it needs every hw/sw resource available. I can't throttle it the whole time, just in certain points when system gets unresponsive, so I could maintain it.

• Optimize Apache performance

  - by Phliplip

  I'm looking for ways to optimize our current web server hosted in-house. I'm trying to supply as much relevant information below. Please let me know if you would require additional information in order to assist. Server is running 1 single website, which is an online pizza ordering platform built on Zend Framework (ver1). On traffic stats from the last month aprox 6.000 pageloads per day, concentrated mainly around dinnertime. Around 1500 loads/hour peaks in that period. We recently upgraded from a 2/2mbit aDSL-line to 100/100mbit fiber, and we still have performance issues at dinner time. We assumed the 2mbit was the issue. Website is pretty snappy in low-load periods. Hardware CPU: Intel(R) Xeon(R) CPU 5160 @ 3.00GHz (3000.13-MHz K8-class CPU) Mem: 328M Active, 4427M Inact, 891M Wired, 244M Cache, 623M Buf, 33M Free Swap: 16G Total, 468K Used, 16G Free (6GB physical, 16GB swap) Filesystem Type Size Used Avail Capacity Mounted on /dev/ad7s1a ufs 4.8G 768M 3.7G 17% / devfs devfs 1.0K 1.0K 0B 100% /dev /dev/ad7s1g ufs 176G 5.2G 157G 3% /home /dev/ad7s1e ufs 4.8G 2.8M 4.5G 0% /tmp /dev/ad7s1f ufs 19G 3.5G 14G 19% /usr /dev/ad7s1d ufs 4.8G 550M 3.9G 12% /var Server OS FreeBSD 8.2-RELEASE Software apache-2.2.17 php5-5.3.8 mysql-server-5.5 Apache footprint (example, taken from # top) 31140 www 1 45 0 377M 41588K lockf 2 0:00 0.00% httpd 31122 www 1 44 0 375M 35416K lockf 2 0:00 0.00% httpd 31109 www 1 44 0 375M 38188K lockf 2 0:00 0.00% httpd 31113 www 1 44 0 375M 35188K lockf 2 0:00 0.00% httpd Apache is using the prefork MPM, APC (Alternative PHP Cache).

• SSL Mail server connection times out on send()

  - by Jivan

  When trying to programmatically send an email from a website of mine, with PHP Pear Mail package with SSL connection, PEAR:Mail replies the following : Failed to connect to example.blabla.net:PORT [SMTP: Failed to connect socket: connection timed out (code: -1, response: )] I looked for similar questions on SO and SF, all the answers asking the OP to test a request on telnet or ssh in command line. So, that is what I did and here is what happens : $ ssh -l myusername -p PORT example.blablabla.net _ Here, '_' in the second line means that NOTHING happens. Indefinitely, which seems coherent with the timeout message I had from PEAR:Mail. So PEAR:Mail seems out of cause. But, what I have to tell you is that yesterday, it just worked. Connection was properly established, mails were properly sent, etc. Just today, it doesn't work anymore and I absolutely don't know why. I restarted Apache (in case an extension was broken), restarted mail services, etc. Still. No effect. Before yesterday (when it worked) and today (when it doesn't anymore), I just didn't touch the server and did nothing on it, simply because I took a day off to write some blog post! Have anyone of you encountered similar problem ? The problem seems quite common, judging after some googling, but the solution doesn't. Thanks for any help ! (note on config : CentOS 6.4 x86_64 with cPanel/WHM)

• What are possible results/side effects if replication between DC's in a Windows domain is unable to occur?

  - by hydroparadise

  There's plenty of administration literature out there how to properly manage Windows servers. But in dealing with real life, things don't always occur like you want them to. In Microsoft's Windows Server 2003 Administrator's Companion, out of 1400+ pages, theres only one page that I could find when it comes up setting up additional domain controlers. They make it sound seemless and don't reveal a whole lot on what happens if "peer" DC's are unable to replicate. Down to the specific issue at hand, we had a DC go down about a month ago due to a bad RAID controller. There was nothing critical that waranted imediate attention, so bringing it back up got put on the back burner. A month later, we get the DC back up and running and everyting seemed ok. The next day, nobody is able to logon complaining that the "user does not exist" or "unable to establish a trust relationship". Knowing that I had just put the downed DC back on the network, I immediately took it back off the network and had everybody restart the workstations. After that, exchange was fine, shares became available, and everybody was able to log in. After doing some event log swimming, it would appear that everything started due to replication issues on the SYSVOL. I've read where you can force replication, but that would mean putting it back on the network. I am afraid to put the DC back on the network in fear that something else could go wrong. So, what other issues could one expect to run into where two DC's are unreplicated for over a month?

• Sudden "No Signal" in HDMI-DVI connection

  - by nazikus

  Yesterday I have connected external display Asus VW192C to my laptop Dell XPS 14-L421X via HDMI-to-DVI-D cable. And it worked perfectly fine from start. The day after, Asus screen went blank showing "No signal". Every time I connection/disconnection cable or power off/on the display it says "No signal". And I didn't change any system configurations meanwhile. To troubleshoot the problem, I have tried to connect laptop to TV (hdmi-to-hdmi) - it was fine. I've tried to connect a different laptop to the display via the same cable - worked fine as well. So its obviously something on system level, either Windows or graphics drivers. Also it seems that Windows still see the external display (I can move mouse pointer away from the main screen in Extended mode), but there's just no signal. Any ideas? What else to try? PS. My laptop has 2 graphics cards - GeForce 630M and Intel HD 4000 using NVidia Optimus technology. I have updated to latest Intel and NVidia drivers, still didn't help. PPS. Although I shouldn't have updated (from Intel support): "our Intel generic graphics drivers from the Intel website do not support using both Intel Graphics 4000 and NVidia GeForece GT630M". Nevertheless, it should not affect connectivity to additional display.

• running a laptop continuously

  - by intuited

  I have an experienced laptop — a Dell Latitude D400, with a Pentium M CPU — that I'd like to run as an always-on server. This model was launched in 2004; I got mine second-hand in about 2007. I've heard that continuous operation is generally not a good idea with consumer hardware, but am lacking in specific knowledge about related problems, and have little idea of how much such usage patterns would reduce the lifespan of the machine. I'm mostly concerned with the unit's core components; parts such as the hard drive which are readily replaceable are, well, readily replaceable. What sorts of things can I do to increase the lifespan of this machine under such circumstances? For example, I'm guessing that it would be wise to limit the CPU frequency or take other steps to keep the internal temperature low. However, I'm not sure where the point of diminishing returns would lie with such an approach — 50°C? 40°C? Would it be useful to suspend the machine periodically, for perhaps an hour each day, or a few hours each week?

• Need a helpful/managed VPS to help transition from shared hosting

  - by Xeoncross

  I am looking for a VPS that can help me transition out of a shared hosting environment. My main OS is Ubuntu, although I am still new to the linux world. I spend most of my day programming PHP applications using a git over SSH workflow. I want PHP, SSH, git, MySQL/PostgreSQL and Apache to work well. Someday after I figure out server management I'll move on to http://nginx.org/ or something. I don't really understand 1) linux firewalls, 2) mail servers, or 3) proper daily package/lib update flow. I need a host that can help with these so I don't get hit with a security hole. (I monitor apache access logs so I think I can take it from there.) I want to know if there is a sub $50/m VPS that can help me learn (or do for me) these three main things I need to run a server. I can't leave my shared hosts (plural shows my need!) until I am sure my sites will be safe despite my incompetence. To clarify again, I need the most helpful, supportive, walk-me-through, check-up-on-me, be-there-when-I-need you VPS I can get. Learning isn't a problem when there is someone to turn too. ;)

• Bacula stops writing to disk volume after 2GB

• zfs pool error, how to determine which drive failed in the past

  - by Kendrick

  I had been copying data from my pool so that I could rebuild it with a different version so that I could go away from solaris 11 and to one that is portable between freebsd/openindia etc. it was copying at 20mb a sec the other day which is about all my desktop drive can handle writing from the network. suddently lastnight it went down to 1.4mb i ran zpool status today and got this. pool: store state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: http://www.sun.com/msg/ZFS-8000-9P scan: none requested config: NAME STATE READ WRITE CKSUM store ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 c8t3d0p0 ONLINE 0 0 2 c8t4d0p0 ONLINE 0 0 10 c8t2d0p0 ONLINE 0 0 0 it is currently a 3 x1tb drive array. what tools would best be used to determine what the error was and which drive is failing. per the admin doc The second section of the configuration output displays error statistics. These errors are divided into three categories: READ – I/O errors occurred while issuing a read request. WRITE – I/O errors occurred while issuing a write request. CKSUM – Checksum errors. The device returned corrupted data as the result of a read request. it was saying low counts could be any thing from a power flux to a disk event but gave no suggestions as to what tools to check and determine with.

• Sharepoint web part fails intermittently

  - by pringly

  I have a MOSS 2007 environment, 2 web servers and a DB server, load balanced between the two web servers. I deployed a web part recently, which worked fine for a while, but failed on web server 2 after a day. When it fails, it gets the error message: 'A Web Part or Web Form Control on this Page cannot be displayed or imported. The type could not be found or it is not registered as safe’ Once it has failed, it will stay that way until an IIS reset is done. The other web server never fails, I tried to force the second web server to fail to recreate the issue and have been unable to do it. I tried placing it under heavy http traffic and it handled it fine. Put it back in the pool and it failed again after about 7 hours. So, if i remove the .dll for the webpart from the affected web server, the webpart doesnt stop working. Is this normal behavior? I checked the bin directory for the site and the global assembly and it there is no other copy of the .dll anywhere else on the server. Also, when checking the web part gallery, if the web part has failed it will appear in the gallery, but by trying to add a new webpart, the .dll wont be listed. I have no idea how to continue troubleshooting from here or even fix it, any ideas?

• Looking for a powershell script that can pull a file from a set of PC's and FTP

  - by DangeRuss

  I'm looking to write a script (preferably powershell) that will essentially copy a file from a bunch of PC's and FTP it to a server. So the structure of the environment is that we have a file on multiple PC's (around 50 or so) that need to placed on a server. Sometimes one of the PC's may be turned off so the script would first need to ensure the PC is up and running (maybe a ping result), then it would need to go into a directory on that PC, pull a file off of it, rename the file, place into a source directory, then remove the file. Naming convention doesn't matter, but date/time stamp would be easiest. Ideally, it would be best to first move all the files to a source directory to save on FTP bandwidth, but since the files will be named the same, the files must be renamed during the move process. Move not copy because the directory needs to be empty so the file can be re-created the next day. So once moved to the source directory, now all the files need to be FTP'd to a server for processing. After all of this, we need to know which PC's on the list did not respond so we can manually retrieve the file so the script should output a file (txt is fine) that will show which PC's were offline. Everything is one domain and script will be run from an server with admin creds. Thank you!

• How do I find and kill a php loop (process)?

  - by Hoytman

  I have a php script that I have been developing which calls an external api within a loop. It is being tested on a VPS which is running LAMP on Debian. I noticed this morning that the api was not responding to my script. When I called the provider, they told me that my server had been calling the api 1000's of times per hour for the past 10 hours. I am assuming that a php script (which I have been working on the day before and testing on my VPS) entered into an infinite loop during one of the executions, and never came out (I have been testing it from the command prompt, and not over the web.) I have attempted to stop and start Apache, but the api support staff says that the calls are still coming in from my server address. How can I find and stop the process? Also, is there a possibility that the Apache stop/start solved the problem, but the api is still trying to sort through past calls? Please forgive me for not using my local test environment correctly. Edit: I do not know the process name, I need to discover the name (or pid) based on behavior.

• Can only ssh when not using wifi

  - by AChrapko

  So I have 3 machines, a windows 7 desktop that is always wired to my router, osX laptop, and raspberry pi running debian linux. My router is a Linksys e1000 wireless N. My goal is to be able to ssh the raspi from any machine, while it is connected via wifi. My problem is that when trying to ssh from either the win7 or osX to the Pi it either times out, or gives an error: "ssh: connect to host 192.168.1.### port 22: No route to host" The only times that I have managed to connect to the pi from any machine were when it connected to the router via an Ethernet cable. Currently with win7 desktop wired, macbook wireless, and pi wireless tests give the following: win7 ping macbook: Destination host unreachable. macbook ping win7: Request timeout. win7 ping pi: Destination host unreachable. macbook ping pi: Request timeout. blah blah blah Plugging the macbook into the router with an Ethernet cable all communication between win7 and macbook works. Pings, ssh, ftp, smb ect... No changes to the pi, still no connections possible to or from any of the other 2 machines. Note All machines, are able to connect to the internet and ssh to the same machine on a completely different network, wired or over wifi. Plugging the Pi in with Ethernet (and macbook still wired) I can ssh to the pi from both win7 and macbook. I can ssh from the pi to macbook. All machines still able to connect the the off network machine. Also another little side note- I was playing warcraft 3 with my roommates the other day, and the only time they were able to see my LAN game was when they were plugged into the router with an Ethernet cable. Once or twice one of the laptops was able to connect over wifi, but not without another computer connecting first via Ethernet. So basically does anyone have any info as to why my router seems to completely ignore local wireless traffic?

• Windows 7 Synchronize folders BUT while some files are open

  - by Nick

  I need some way to synchronize 2 drives I have. I want to do this ofter (once a day or so) There is the main drive that I want to clone/synchronize on a backup hard disk. The problem is in that there is an open TrueCrypt file mounted as a drive, and its live. If you don't know what true crypt is, basically you create a file on a hard disk and that file is encrypted. It's constantly open and modified live. Also Its pretty large. 100GB + I will use freefilesync . There are many tools that can do that. My question is, is it safe to copy the encrypted file while its open ? Does the software freeze the file in one state and copies it ? Or will I get a corrupted file on the other drive ? It was not clear to me how windows handles that. I read something about shadow copy, and the software says that it supports this. Does anyone know something on the matter that can help me ? or some software that will work ok in my scenario ? Thanks

• Migrate active directory to Google apps for business

  - by dewnix

  I've got a problem migrating active directory to Gapps. I'm stuck on google apps directory sync (GADS) where it just gives the error "java.lang.NullPointerException" after testing the connection during the LDAP configuration step. I checked the logs and I've pretty much determined that port 389 (standard LDAP port) isn't listening on the exchange server. I've tried telneting to it (from another machine in the same network) with no luck but I can telnet to other ports, that i know are open, successfully. I know they're open because I used portqry and netstat to see them. I'm suspecting that the active directory isn't even installed/running on this machine because there's no active directory services at all running on it. There's no active directory services that say they're NOT running either though. Is it possible AD is installed somewhere else? does it have to be on a machine inside the same network? I found the domain controller and it's host name and when I telnet with port 389, it works however GADS still gives me the same exact error when I substitute that server in. Actually, no matter what ridiculous settings i put into GADS, i still get that same NullPointer error. If i could get some different error than that NullPointer, i'd call that a successful day.

• locale: What is the LANGUAGE variable used for? (and when?)

  - by seya

  I am trying to understand the locales used in Linux. On my Ubuntu 11.10 system locale puts out the following: LANG=en_DK.UTF-8 LANGUAGE=en_GB:en LC_CTYPE=en_GB.UTF-8 LC_NUMERIC="en_DK.UTF-8" LC_TIME="en_DK.UTF-8" LC_COLLATE=en_GB.UTF-8 LC_MONETARY="en_DK.UTF-8" LC_MESSAGES=en_GB.UTF-8 LC_PAPER="en_DK.UTF-8" LC_NAME="en_DK.UTF-8" LC_ADDRESS="en_DK.UTF-8" LC_TELEPHONE="en_DK.UTF-8" LC_MEASUREMENT="en_DK.UTF-8" LC_IDENTIFICATION="en_DK.UTF-8" LC_ALL= (en_dk is for using international day format, continental European number formatting (1.234,56) etc.) I think I understand what the LC_* family does, that LANG is the fallback if one of them is not set and that LC_ALL sets all of the LC_* variables to its value. What I don't know yet, is what LANGUAGE is used for. The notation en_GB:en reminds me of the Accept-Language HTTP header. With the settings above it would mean, British English is used, if a translation for it exists. Otherwise any existing English translation (en_US, en_AU, ..., whatever) would be used. Am I right so far? Also what programs actually obey the LANGUAGE setting? In how far is it different from LC_MESSAGES? Unfortunately, man locale only documents the LC_* family. And searching the web for 'linux locale LANGUAGE' or similar is a mute point. (Of course language is a word often used when talking about locales, and it may also be shown just in the output of locale without being discussed). Does anybody of you can help me out there?

• Windows 7 Account Settings Vanished

  - by Roy Tang

  So I came home and stumbled upon a bit of a mystery. When I got home my brother was using my desktop PC that was running Windows 7 (I have accounts for my 2 brothers and my mom on the machine, but mine is the only admin account). After he finished his game he logged out and I logged in to my account, but found only strangeness. My windows account seems to have been somewhat "reset", meaning: my quick launch shortcuts were gone my dropbox account did not automatically login my pidgin accounts were no longer there I had to relogin Steam iTunes could not launch (I had hooked up my iDevice before logging in) The Documents/Pictures/Music shortcuts in the start menu no longer work However, despite that: my desktop wallpaper was still correct my documents folder was still there in c:\Users\my account name\My Documents as expected Google Chrome settings seem to have been retained other accounts on the same machine seem to be fine I asked my brother if he had installed anything strange during the day, he only installed Yahoo Messenger. I last used the machine around 24 hours ago and it was fine then. I'm not sure what else has been affected. I'm inclined to just create a new admin user for me to use, but I'd like to have some idea of what actually happened.
