• DRBD Replication failure

  - by user62513

  A couple of weeks ago I setup a 2 nodes CRM system with one of the resources managed being MySQL over DRBD. Today for maintenance reasons I restarted both nodes but now they can't connect to each other anymore. DRBD fell out of sync and I followed this guide to get it back connected but it's only able to run successfully on one node. But this strange thing happens: If I crm node standby both nodes and I try: crm node online node0 before crm node online node1, all the CRM resources start successfully but the DRBD partitions are still running in StandAlone state. crm node online node1 beofre crm node online node0, the DRBD resource fails to start, thus causing mysql not to start. If I standby both resources and call crm node online node0 then it times out and prints this error: Running crm node online node0 produces this output after timing out Error setting standby=off (section=nodes, set=<null>): Remote node did not respond Error performing operation: Remote node did not respond Is there anything I'm doing wrong here? An alternative will be just do MySQL replication but I'm not sure how to promote a slave to master when the master database is not available.

• Are my Linux symbolic links acting correctly?

  - by Andy Castles

  Hi all I've been using Linux on and off for the last 15 years and today I came across something in bash that surprised me. Setup the following directory structure: $ cd /tmp $ mkdir /tmp/symlinktest $ mkdir /tmp/symlinktest/dir $ mkdir /tmp/symlinktarget Now create two sym links in symlinktest pointing to symlinktarget: $ cd /tmp/symlinktest $ ln -s ../symlinktarget Asym $ ln -s ../symlinktarget Bsym Now, in bash, the following tab completion does strange things. Type the following: $ cd dir $ cd ../A[TAB] Pressing the tab key above completes the line to: $ cd ../Asym/ as I expected. Now press enter to change into Asym and type: $ cd ../B[TAB] This time pressing the tab key completes the link to: $ cd ../Bsym[space] Note that there is now a space after the Bsym and there is no trailing slash. My question is, why when changing from the physical directory "dir" to Asym it recognises that Asym is a link to a directory, but when changing from one sym link to another, it doesn't recognise that it's a link to a directory? In addition, if I try to create a new file within Asym, I get an error message: $ cd /tmp/symlinktest/Asym $ cat hello > ../Bsym/file.txt -bash: ../Bsym/file.txt: No such file or directory I always thought that symlinks were mostly transparent except to programs that need to manipulate them. Is this normal behaviour? Many thanks, Andy

• SSH Private Key Not Working in Some Directories

  - by uesp

  I have a strange issue where SSH won't properly connect with a private-key if the key file is in certain directories. I've setup the keys on a set of servers and the following command ssh -i /root/privatekey [email protected] works fine and I login to the given host without getting prompted by a password, but this command: ssh -i /etc/keyfiles/privatekey [email protected] gives me a password prompt. I've narrowed it down that this behavior occurs in only some sub-directories of /etc/. For example /etc/httpd1/ gives me a password prompt but /etc/httpd/ does not. What I've checked so far: All private key files used are identical (copied from the original file). The private key file and directories used have identical permissions. No relevant error messages in the server/client logs. No interesting debug messages from ssh -v (it just seems to skip the key file). It happens with connecting to different hosts. After more testing it is not the actual directory name. For example: mkdir /etc/test cp /root/privatekey /etc/test ssh -i /etc/test/privatekey [email protected] # Results in password prompt cp /root/privatekey /etc/httpd # Existing directory ls -ald test httpd # drwxr-xr-x 4 root root 4096 Mar 5 18:25 httpd # drwxr-xr-x 2 root root 4096 Mar 5 18:43 test ssh -i /etc/httpd/privatekey [email protected] # Results in *no* prompt rm -r test cp -R /etc/httpd /etc/test ssh -i /etc/test/privatekey [email protected] # Results in *no* prompt` I'm sure its just something simple I've overlooked but I'm at a loss.

• PostgreSQL pg_hba.conf with "password" auth wouldn't work with PHP pg_connect?

  - by tftd

  I've recently experimented with the settings in pg_hba.conf. I read the PostgreSQL documentation and I though that the "password" auth method is what I want. There are many people that have access to the server PostgreSQL is working on so I don't want the "trust" method. So I changed it. But then PHP stopped working with the database. The message I get is "Warning: pg_connect(): Unable to connect to PostgreSQL server: FATAL: password authentication failed for user "myuser" in /my/path/to/connection/class.php on line 35". It is kind of strange because I can connect via phppgadmin without any problems and also I can connect from my home computer with psql - again without any problems. This is my pg_hba.conf: # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all password # IPv4 local connections: host all all 127.0.0.1/32 password # IPv6 local connections: host all all ::1/128 password The connection string I'm using with pg_conenct is: $connect_string = "host=localhost port=5432 dbname=mydbname user=auser password=apassword"; $dbConnection = pg_connect($connection_string); Does anybody know why is this happening ? Did I misconfigured something ?

• Local references to old server name remain after Windows 2003 server rename

  - by imagodei

  I have a standalone Win 2003 server with Windows Sharepoint Services (WSS3) running on it. I had to rename the server and I had bunch of problems resulting from this. Note that the server is not in AD environment. Most obvious problems were with Sharepoint, which didn't work. I was somewhat naive to think it will work in the first place, but OK - I've solved this using step 1 & 3 from this site (TNX) Other curious behavior/problems remain. Most disturbing is that Sharepoint isn't able to send email notifications to participants. I noticed there are several references to old server name everywhere I look: in Registry, in Windows Internal Database (MICROSOFT##SSEE). I see instances of old server name in the Sharepoint Central Administration - Operations - Servers in farm. There is reference to a servers: oldname.domain.local oldname.local On one of those servers there is also Windows SharePoint Services Outgoing E-Mail Service (Stopped). Also, when I try to telnet locally to the mail server (Simple Mail Transfer Protocol (SMTP) service), I get a response: 220 oldname.domain.local Microsoft ESMTP MAIL Service, Version: 6.0.3790.4675 ready at Tue, 15 Jun 2010 13:56:19 +0200 IMO these strange naming problems are also the reason why email notifications from within Sharepoint don't work. Can anyone tell me how to correct/replace those references to oldservername? Why is the email service insisting on old name? Of course I would like to try it without reinstalling the server. TNX!

• python reports socket in use, netstat and others claim its not

  - by captainmish

  We have a strange socket issue with a RHES3 box: Python 2.4.1 (#1, Jul 5 2005, 19:17:11) [GCC 3.2.3 20030502 (Red Hat Linux 3.2.3-52)] Type "help", "copyright", "credits" or "license" for more information. >>> import socket >>> s = socket.socket() >>> s.bind(('localhost',12351)) Traceback (most recent call last): File "<stdin>", line 1, in ? File "<string>", line 1, in bind socket.error: (98, 'Address already in use') This seems normal, lets see what has that socket: # netstat -untap | grep 12351 {no output} # grep 12351 /proc/net/tcp {no output} # lsof | grep 12351 {no output} # fuser -n tcp 12351 {no output, repeating the python test fails again} # nc localhost 12351 {no output} # nmap localhost 12351 {shows port closed} Other high ports work fine (eg 12352 works) Is there something magic about this port? Is there somewhere else I can look? Where does python find out that socket is in use that netstat doesnt know about? Any other way I can find out what/if that socket is?

• Is my webserver being abused for banking fraud?

  - by koffie

  Since a few weeks i'm getting a lot of 403 errors from apache in my log files that seem to be related to a bank frauding scheme. The relevant log entries look like this (The ip 1.2.3.4 is one I made up, I did not modify the rest of each line) www.bradesco.com.br:80 / 1.2.3.4 - - [01/Dec/2012:07:20:32 +0100] "GET / HTTP/1.1" 403 427 "-" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11" www.bb.com.br:80 / 1.2.3.4 - - [01/Dec/2012:07:20:32 +0100] "GET / HTTP/1.1" 403 370 "-" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11" www.santander.com.br:80 / 1.2.3.4 - - [01/Dec/2012:07:20:33 +0100] "GET / HTTP/1.1" 403 370 "-" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11" www.banese.com.br:80 / 1.2.3.4 - - [01/Dec/2012:07:20:33 +0100] "GET / HTTP/1.1" 403 370 "-" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11" the logformat I use is: LogFormat "%V:%p %U %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" The strange thing is that all these domains are domains of banks and 3 out of the 4 domains are also in the list of the bank frauding scheme described on: http://www.abuse.ch/?p=2925 I would really like to know if my server is being abused for bank frauding or not. I suspect not, because it's giving 403 to all requests. But any extra checks that I can do to ensure that my server is not being abused are welcome. I'm also curious on how the "bad guys" expected my server to behave. I.e. are they just expecting my server to act as a proxy to hide the ip of the fake site, or are they expecting that my server will actually serve the fake banking website? Is the ip 1.2.3.4 more likely to be the ip of a victim or the ip of a bad guy. I suspect a bad guy, because it's quite unlikely that a real person would visit 4 bank sites in a second. If it's from a bad guy I'm very curious at what he is trying to do.

• IP Phone over VPN - one way calls unless default route?

  - by dannymcc

  I have come across a strange problem with our VPN and BCM 50 (Nortel/Avaya) phone system. As you can tell by my other questions I have been doing some work on setting a VPN up from one location to another and it's all working well. With one exception. We have an IP phone that is connected at the remote location, straight to a router which has a VPN tunnel to our main practice. The phone works mostly, but every few calls it turns into a one way call. As in, the caller (from the remote phone) can't hear the receiver- but the receiver can hear the caller. This is fixed by setting the VPN tunnel to be the default route for all traffic. The problem with fixing it that way is that all traffic then goes through the tunnel which slows internet access etc. down considerably. The router is set to send the following over the VPN: 192.168.1.0/24 192.168.2.0/24 192.168.4.0/24 The IP of the remote location is: 192.168.3.0/24 The remote router (where the phone is) is a Draytek 2830n, and the local router (at the main practice) is a Draytek 2820. We are using an IPSec tunnel with AES encryption <- as a result of a previous answer pointing to the incompatibility in the hardware encryption. Any advice would be appreciated!

• Installing ffmpeg + dependencies on AWS Linux AMI (repo issues)

  - by HdN8

  I'm installing ffmpeg to run on an Amazon linux AMI, and have added the rpmforge repo and the dag repo. Here are some guidelines I'm using for reference: TWoZaO and Razuna The rpmforge repo has ffmpeg, but if you try to install it then it will complain that is missing dependencies (for me libSDL-1.2.so.0()(64bit)). Regardless I will install ffmpeg from svn so I can be sure to enable the options I want (namelylibx264). It seems strange to me though that SDL is not inrpmforgeordag`, and in according to both of my references above, it should be there. I tried to grab it manually from here, but it needs these dependencies, so no-go: > error: Failed dependencies: SDL = > 1.2.10-8.el5 is needed by SDL-devel-1.2.10-8.el5.x86_64 > alsa-lib-devel is needed by > SDL-devel-1.2.10-8.el5.x86_64 > libGL-devel is needed by > SDL-devel-1.2.10-8.el5.x86_64 > libGLU-devel is needed by > SDL-devel-1.2.10-8.el5.x86_64 > libSDL-1.2.so.0()(64bit) is needed by > SDL-devel-1.2.10-8.el5.x86_64 > libX11-devel is needed by > SDL-devel-1.2.10-8.el5.x86_64 > libXext-devel is needed by > SDL-devel-1.2.10-8.el5.x86_64 > libXrandr-devel is needed by > SDL-devel-1.2.10-8.el5.x86_64 > libXrender-devel is needed by > SDL-devel-1.2.10-8.el5.x86_64 > libXt-devel is needed by > SDL-devel-1.2.10-8.el5.x86_64

• SQL Error (1064) when importing data from SQL file

  - by mejpark

  I have a MySQL database, which was originally set up with the default latin1 character set and latin1_swedish_ci collation. I was using the database like this for sometime, until I noticed strange characters on my production web site, which is powered by a database exported from my development machine. At this point, I changed the default character set of the database and tables to utf8 and the collation to utf8_unicode_ci, converted the latin1 data inside each table to utf8 (using the 'convert data' option) and exported the database as a single SQL file using HeidiSQL. When the resulting SQL file is opened in Notepad++, several characters are rendered incorrectly. For example, en dashes (-) are displayed as – and e with accent (é) are displayed as é. I changed the encoding of the file from ANSI to UTF-8 (using the encoding menu option in Notepad++) and the offending characters are rendered correctly. I saved the new utf8-encoded SQL file and attempted to import the contents into the MySQL database on my production server. The import process fails with following error: /* SQL Error (1064): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?# -------------------------------------------------------- # Host: ' at line 1 */ /* Error with snippets directory: The specified path was not found */ The head of the SQL file: # -------------------------------------------------------- # Host: 127.0.0.1 # Server version: 5.1.33-community # Server OS: Win32 # HeidiSQL version: 6.0.0.3773 # Date/time: 2011-04-20 09:48:36 # -------------------------------------------------------- It chokes on the first line of the file, which is commented out. Why is this happening? I didn't have a problem loading data from SQL files until I changed the character set and collation of the database. I came up with an ugly workaround to this problem by performing following steps: Export database as single SQL file using HeidiSQL Open resulting file in Notepad++ and convert from ANSI to UTF-8 encoding Create new empty file in Notepad++, paste in UTF-8 and save file normally What am I missing here?

• What precautions should I take once defective RAM has been replaced?

  - by DustByte

  I recently discovered that my RAM is faulty (MemTest86+). I am waiting for new RAM to be sent to me.  It was through sheer luck that I discovered something was wrong. I was copying a large amount of big files and decided to verify the copies by their checksums. I discovered strange discrepancies, and noticed that checksum computation for the same file was not consistent. Now, this is the only problem I have encountered; no BSOD, no crashes, no errors. In a sense this makes me more worried than if I would have had massive crashes. I have no idea for how long the RAM has been faulty, and I have no idea if corrupt bits have been saved into files on my hard drives. I do know the RAM was fine two months ago (tested it back then). I am a user of Adobe's Lightroom and I am worried that photos or the catalog itself could carry corrupt data. Question: what should I do once new healthy RAM has been installed? Reinstall Windows (I'm using Windows 7, 64 bit)? Is there a risk that I will be presented with nasty surprises in the future if I don't? What about personal files? I have backups of some of the files but for newer files I'm not sure I can even trust the backups. It's going to take me many hard hours to manually replace files with older versions, or compare checksums.

• Application (was Firefox) crash on first load on Ubuntu Linux on older Dell Laptop

  - by Ira Baxter

  I've had a Dell Latitude laptop since about 2000 without managing to destroy it. A month ago the Windows 2000 system on it did something stupid to its file system and Windows was completely lost. No point in reinstalling Windows 2000, so I installed an Ubuntu Linux on the laptop. Everything seems normal (installed, rebooted, I can log in, run GnuChess, poke about). ... but ... when I attempt to launch Firefox from the top bar menu icon, I get a bunch of disk activity, the whirling cursor icon goes round a bit and then (WAS: everything stops: icon, mouse. Literally nothing happens for 5 minutes. Ubuntu is dead, as far as I can tell. EDIT : on further investigation, spinning icon, mouse operated by touchpad freeze. There's apparantly a little disk activity occuring about every 5 seconds. I wait 5-10 minutes, behavior doesn't change) A reboot, and I can repeat this reliably. So on the face of it, everything works but Firefox. That seems really strange. The only odd thing about this system when Firefox is booting is that while it has an Ethernet port (that worked fine under Windows), it isn't actually plugged into an Ethernet. As this is the first Firefox boot since the Ubuntu install, maybe Firefox mishandles Internet access? Why would that crash Ubuntu? (I need to go try the obvious experiment of plugging it in). EDIT: I tried to run the Disk manager tool, not that I cared what it was, just a menu-available application. It started up like Firefox, I get a little tag in the lower left saying Disk P*** something had started, and then the same behavior as Firefox. At this point, I don't think its the Ethernet. Is it possible that the Ubuntu disk driver can't handle the disk controller in this older laptop? The install seemed to go fine.

• Asus K55VM usb 3.0 issue

  - by user2141481

  Good day superusers! I own the above laptop and I found out that there are some unknown and unusual issues with usb 3.0 ports. I haven't noticed anything strange until now. I got a new toshiba usb 3.0 external hdd and when I try to copy larger amount of data from my disk to the external hdd, the OS(windows 7) randomly starts ignoring the external hdd. It doesn't shut it down, it kinda just stops responding but the light on the hdd is still lit. I get an error that the files cannot be copied. I have reinstalled windows 7, installed all drivers(including intel chipset drivers of course) and the issue is still present. It acts normal when copying small amount of data. Also, I heard that some intel chipsets have an issue with usb, something about the connectors not transferring power when the usb device enters some kind of "low power mode" causing the device to stop responding and you need to plug it out and in again. But the thing is, my Intel® Chief River Chipset HM76 is not on the list of affected hardware(not ENTIRELY sure though). If anyone has any idea of what the problem to this might be, I'd be greatful. Edit: The hdd works perfectly fine even for large amounts of data if plugged in the usb 2.0 port!

• Can't access one directory via HTTPS + public FQDN

  - by Justin James

  Hello - I have the strangest IIS error that I've ever seen in my life. I have an application/directory on an IIS server, that throws an error 500 when accessing ANY of the content in it, including HTML documents, when accessed via HTTPS AND the machines FQDN. When I access it with "localhost" it works fine. When I added a bogus entry for the NIC's IP in the hosts file, it worked fine. When I access it with the machines name and HTTP it works fine. Here's a chart (the machine's name is "lofn.titaniumcrowbar.com"): http - lofn.titaniumcrowbar.com: works https - lofn.titaniumcrowbar.com: broken https - localhost: works https - temp.titaniumcrowbar.com (put into hosts file): works I set up tracing, and I got some useless information: "The I/O operation has been aborted because of either a thread exit or an application request. (0x800703e3)" This would make sense, except this happens when pulling up static content. While the directory may be an "application", the content is all static in it. Any/all suggestions, no matter how strange, are VERY appreciated. Thanks! J.Ja

• NTFS permissions weird inheriance (second take!)

  - by Wil

  A complete re write of my previous question, in a different context. Basically, the issue is that when I create a new user within a new group, the new user has various permissions over various folders. I have deleted the group "users" from this user object, and it is simply a member of the group "test". I have created a folder called c:\foo, when I go to effective permissions under the security tab, I can see that the user "lockdown" has various permissions. As far as I can see, there is nothing that should allow lockdown access. The moment I remove users from this list, it behaves as I would expect, which makes me believe that for some strange reason, the users group behaves like the everyone group and is controlled by the system. That being said, I cannot understand this as under the list, it is not there - and further to this, with the same permissions as the first picture, guest does not have access. This has stumped me and any help is appreciated! (Tested in Windows 2003 and 2008) edit - Should also say that if I go to Effective Permission for the group the user is in, there are no boxes checked, so it is somehow just the user that is getting the permissions from somewhere.

• Emptying Windows temp folder is a good idea?

  - by Siva Charan

  Am using DELL Inspiron with Windows 7. As far as I know emptying the windows temp folder would be good. But I faced a strange behaviour around 8 months back, when I clear my windows temp folder. The next day onwards, my laptop starting displaying daily one or other errors and one day OS got crashed. Till now I am not sure whether OS got crashed due to clearing the windows temp folder or something else is problem. Here Windows temp folder mean "C:\Windows\Temp" This is the behind the story. Today, this temp folder "C:\Windows\Temp" contains 102 GB Most of the space occupied by the files starts with etilqs_*.*. I came to know that these files are generated due to WD SmartWare. Now my problem is:- Actually I want clean up this folder, since it occupies lot of space. If I clean up "C:\Windows\Temp" folder, will my laptop face the same kind of problem which I faced earlier OR Any new problems will occur? Please suggest me a good solution.

• hp DL380 G4 won't boot with disk plugged into front USB

  - by Kev

  We outgrew a few older external USB backup drives, and purchased WD My Passport 1 TB USB 3.0 drives to replace them. When they are plugged into the front of our G4, it will blink forever after the BIOS (which is current, BTW) and never boot, even though the USB disks are not "bootable" per se. Our old drives did not exhibit this behaviour (so I don't think it's this type of issue that I've read about other servers.) The old drives were USB 2.0, but this shouldn't make a difference, AFAICT--the specs say all of the G4's USB ports are the same, 2.0, anyway, so I'm not sure how one port would handle a USB 3.0 device better than another. If we plug the new drives in one of the back slots, it boots fine. What's the cause? My concern is that the front USB port, and possibly the motherboard, might be starting to die. (We are experiencing other strange issues with them, or were initially, like intermittent file permissions errors despite wide-open ACL on these local drives, but some serverfault users have me convinced they may be coincidental software/security related issues.)

• Determining the Source of a Given File System Mount on Unix [migrated]

  - by phobos51594

  Background Recently I have run into a bit of a snag on my home FreeBSD server. I recently upgraded it to the latest stable release, and I have noticed some strange behavior with the /var partition. Originally, I had the system configured such that /var had its own partition with /var/run and /var/log in memory disks (/tmp, too). After the upgrade, I notice there is a new, fourth memory disk mounting directly to /var that I had not set up manually and is not in my fstab. It is only 28 megs or so in size and is causing problems when trying to update my ports collection. The ramdisk mounts atuomagically at boot and cannot be unmounted while in multi-user mode. If I drop to single user mode, I am able to unmount it without issue, however rebooting causes it to pop right back up. System specifications have been included at the end of the post. Question Is there any way to determine exactly what is mounting a given memory disk (or any filesystem, for that matter) after it has been mounted? Alternately, does anybody have any ideas what might have caused the new /var ramdisk to pop up? System Specification # uname -a FreeBSD sarge 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #0: Thu Nov 22 14:02:13 PST 2012 donut@sarge:/usr/obj/usr/src/sys/GENERIC i386 # df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/da0s1a 515612 410728 63636 87% / devfs 1 1 0 100% /dev /dev/da0s1d 515612 287616 186748 61% /var /dev/da0s1e 6667808 2292824 3841560 37% /usr /dev/md0 63004 32 57932 0% /tmp /dev/md1 3484 8 3200 0% /var/run /dev/md2 31260 8 28752 0% /var/log /dev/md3 31260 512 28248 2% /var <-- This # cat /etc/fstab # Device Mountpoint FStype Options Dump Pass# /dev/da0s1a / ufs rw,noatime 1 1 /dev/da0s1d /var ufs rw,noatime 2 2 /dev/da0s1e /usr ufs rw,noatime 2 2 md /tmp mfs rw,-s64M,noatime 0 0 md /var/run mfs rw,-s4M,noatime 0 0 md /var/log mfs rw,-s32M,noatime 0 0 Thank you in advance for any assistance.

• prevent IE8 tabs from opening as a new "process in the taskbar"

  - by Nano8Blazex

  This may have been asked before too... But, anyways. I'm using Windows 7 Ultimate, and IE 8, and have the taskbar in icon view. I'm not sure how to explain this, but I'm amazed at how each tab in IE8 seems to act like a new "process" in the taskbar (as if each tab was a window). Like... each tab acts like a different window in the taskbar although they are actually running in the same window. Now when I use IE 8 it looks (in the taskbar) like there's 15 windows open when in fact the taskbar is simply showing the 15 tabs. More simply put, it's displaying a "stack" for all of the tabs when I'd rather have the icon act like, for example, firefox so that a stack is only shown for the multiple windows. I know that they are meant to be running as separate processes to prevent crashing and the such... but is there a way to disable this strange "taskbar" effect? I'd rather have the taskbar show the main window and not the tabs individually.

• My Windows 7 has suddenly stopped displaying Unicode symbols

  - by Felix Dombek

  For some strange reason, my computer suddenly doesn't show certain unicode characters anymore! I have no idea what happened. Affected applications include Windows Explorer (should be Japanese characters), Google Chrome (should be a heart), and Winamp (should be stars): Russian, German etc. characters are displayed normally. Chrome also displays Japanese script on websites, but not in the GUI. How can I fix it? Update: I have tried to use System Restore to fix it. I needed to go back in time quite a while because the most recent restore points didn't solve it so I used one from the middle of November. After that restore, Unicode symbols were displayed again. Then I updated my system with Windows Update again because those were removed during the restore. After that, the error occurred again! I then did a restore to a point before my new updates, but the error persists, and the old restore point (which I used before) is gone and there are currently no other snapshots of the system. Any suggestions on what to do now? Update 2: I could find a workaround: Control Panel ? Region and Language ? Administration ? Change Language for Unicode-incompatible programs to Japanese (Japan). All mentioned programs display their symbols correctly again. However, I don't consider this a fix because these programs are not usually Unicode-incompatible, and it also leads to some (non-serious) artifacts in some programs. I still welcome an answer that tells me what went wrong here and how to fix the issue.

• Unable to Connect to just Google Servers

  - by Akshat Mittal

  I am in an extremely strange problem. I am unable to connect to just Google Servers. I am not able to access any site related to Google, Google.com | YouTube | Google+ | Webmaster Tools | jQuery CDN, nothing is working. I am able to open any other website (as I am posting this question on SuperUser), even the Google DNS (8.8.8.8 and 8.8.4.4) are offline. Please Help!! Update 1: Google DNS are back online, YouTube is back online. But website on domain google.com is not working (ex: play.google.com, maps.google.com, google.com/search, etc). Update 2: I am able to access Google.com (only) with (one of) its IP addresss(s) listed below: 74.125.227.41 74.125.227.46 74.125.227.32 74.125.227.33 74.125.227.34 74.125.227.35 74.125.227.36 74.125.227.37 74.125.227.38 74.125.227.39 74.125.227.40 Update 3: I consulted my friends nearby and they said that they are also experiencing the same problem. Seams like this is a major problem in this area (or India !!) The Problem is Now Solved!! I am able to open Google.com

• SQL Server becomes slow after restart

  - by Tobi DM

  I already posted this one on stackoverflow but someone gave me the hint to that I might have more luck on serverfault. We use SQL Server 2005 on an Windwos Server 2008. Ther Server has 48 GB RAM. SQL Server is configured to use 40 GB RAM. There is only one database hosted (About 70 GB). The only app beside SQL Server is our App-Server which connects the clients to the database. Now we encounter the following problem: After a restart of the server our the performance is great. The server grabs the 40 GB RAM wich it is allowed to and then runs fast as hell. But after about 4 weeks the system becomes slower and slower. The execution of statements (seen in the profiler) is raising slowly. But I cannot see that there is something going wrong on the server. CPU usage is at about 20% I/O also seems to be no Problem The process monitor does also not show that there are strange apps or something like that. Eventlog does also have no interessting messages No open transactions or blockings to see We do not use cursors in our app We tried already the following things without effect: Droped the cache by using the statements DBCC FreeProcCache DBCC FREESYSTEMCACHE('ALL') DBCC DropCleanbuffers Restarted the Appserver we are using. Restart the sql server service But nothing did help exept restarting the whole server. Any ideas?

• HP Pavillion DV6500 recovery disk failure

  - by Scott W

  I recently attempted to re-install Windows Vista on an HP Pavillion DV6500 using the factory recovery DVD's, but encountered a strange problem. When the recovery disk attempted to reformat the hard disk, it failed at 22%. The error message provided was not very informative, just the error code "0x400110020000 1005". A google search turned up some people with a similar problem who asserted that HP has been know to ship corrupted recovery DVDs. The recovery disk did manage to reformat the the recovery partition before failing though, so recovering from the partition is no longer an option. It would be possible to reinstall from an off-the-shelf retail copy of Vista and then pull the drivers from HP's website, but I don't have access to a copy of Vista, and it would really be outrageous to have to purchase a new OS when I have a perfectly valid license already. Thought about biting the bullet and upgrading to Windows 7, but my understanding is that without Vista installed I'd be unable to use the upgrade version, and be forced to purchase the more expensive non-upgrade retail copy (!). Can anyone suggest a possible solution to this Catch-22? I've run out of ideas.

• Suddenly can't send E-Mails with Apple Mail to Gmail SMTP

  - by slhck

  Hi all, I have a weird problem that started just today. I am using Apple Mail on a Leopard machine, connecting to Gmail. Fetching e-mail works just fine. My SMTP settings are also correct. Still, I can't send mail, it will display a pop up saying that "transferring the content to the mail server" failed (translation from German, could be different in English OS X versions). I have verified the following: My SMTP settings are definitely correct. I have not changed them and the issue appeared today. Also, I went through the Apple online configuration for Gmail accounts and did not have to adjust any setting. I can run network diagnosis and it will connect to both POP and SMTP servers without a problem (all green lights) The Telnet details will show me the HELO message from the Gmail servers, so there's no authentication failure. Console.app will not show any messages related to "mail" when I try to send the mail, so there's no specific error message The mail I'm trying to send does not have an attachment, it is plaintext only I can login to gmail.com and send mails without a problem The recipient address exists and contains no syntax errors I can also not send mails to myself When using another IP and ISP (through VPN), it still doesn't work As for my settings: I connect to smtp.gmail.com and for advanced settings I choose password-based authentication with user: [email protected] and my password. I let Apple Mail try the default ports (for SSL and TLS, respectively). Again: I have not changed a thing between yesterday and today. What is causing that strange behavior? Any help would be much appreciated.

• illegitimate traffic from user agent Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729)

  - by user114293

  Since the beginning of the year, I'm getting a lot of traffic with the user agent Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729). My access logs show 40% - 60% from that user agent. That's strange because the user agent states a Firefox 3.0.10 browser (is anybody using that browser in 2012? Definitely not 40%-60% of visitors on a normal website). Also, the logs show that this user agent only requested the HTML document and no referenced assets like images, css, js files. I checked the IPs of those requests (with that UA). It's coming from all over the world. I recognized that those IPs sometimes have a mobile user agent. So my suspicion is a mobile app that is doing a lot of "spider requests" - but if that would be the case than other web sites should have the same problem. That's actually my question: Does anybody experience same/similar problems?
