• ATI gpu (video accel, decode, encode, ATI Stream, DXVA)

  - by Shiki

  Okay its a long question title for sure. I'm looking for a new video card (yes,SU is not a page for that, but wait). I've been a loyal NVidia customer ever since, now using a 8600gts. Old but still somewhat good, its a bit slow though. I want an upgrade because 8600gts wont support better vdpau and new features. I checked out the prices and the documents, I would need a GTX260 card. Which costs ..well.. a lot. ATI performs much better for that price. (At least on every test it outperforms GTX260). However, as far as I know there is no gpu accel with ATI. The things you can use is DXVA only, no other method. Could you correct me out there? Will be there a gpu accel for ATI also? Or is there one available? (DXVA is not bad, but kinda slow compared to NVIdia's CUDA.) What about openCL? How does ATI support that? (I'm talking about the 5850 ATI card at the minute, I would buy that instead of the NVidia.)

• How much network latency is "typical" for east - west coast USA?

  - by Jeff Atwood

  At the moment we're trying to decide whether to move our datacenter from the west coast (Corvallis, OR) to the east coast (NY, NY). However, I am seeing some disturbing latency numbers from my location (Berkeley, CA) to the NYC host. Here's a sample result, retrieving a small .png logo file in Google Chrome and using the dev tools to see how long the request takes: Berkeley to NYC server: 215 ms latency, 46ms transfer time, 261ms total Berkeley to Corvallis server: 114ms latency, 41ms transfer time, 155ms total some URLs if you want to try yourself: http://careers.stackoverflow.com/content/cso/img/logo.png (NY, NY) http://serverfault.com/cache/logo.png (Corvallis, OR) It makes sense that Corvallis, OR is geographically closer to Berkeley, CA so I expect the connection to be a bit faster.. but I'm seeing an increase in latency of +100ms when I perform the same test to the NYC server. That seems .. excessive to me. Particularly since the time spent transferring the actual data only went up 10%, yet the latency went up ten times as much! That feels... wrong... to me. I found a few links here that were helpful (through Google no less!) ... http://serverfault.com/questions/63531/does-routing-distance-affect-performance-significantly http://serverfault.com/questions/61719/how-does-geography-affect-network-latency http://serverfault.com/questions/6210/latency-in-internet-connections-from-europe-to-usa ... but nothing authoritative. So, is this normal? It doesn't feel normal. What is the "typical" latency I should expect when moving network packets from the east coast <--> west coast of the USA?

• Openconnect for Cisco VPN doesn't recognize private key file - asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag

  - by Alexander Skwar

  I'm trying to use my Synology DS212 NAS box also act as VPN gateway to my companies VPN. Sadly, they only use Cisco ASA and to complicate stuff even further, we've got to use personal certificates (which is of course more secure, but more complicate to get going…). So I compiled OpenConnect v4.06 from http://www.infradead.org/openconnect/. As a very basic test, I tried to build a connection by manually invoking openconnect, passing along the key and cert files, like so: /lib/ld-linux.so.3 --library-path /opt/lib \ /opt/openconnect/sbin/openconnect \ --certificate=$VPN_CFG/alexander.crt \ --sslkey=$VPN_CFG/alexander.key \ --cafile=$VPN_CFG/Company_VPN_CA.crt \ --user=alexander --verbose <ip>:443 It fails :( Attempting to connect to <ip>:443 Using certificate file $VPN_CFG/alexander.crt Using client certificate '/[email protected]/OU=Company VPN' 5919:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1315: Loading private key failed (see above errors) Loading certificate failed. Aborting. Failed to open HTTPS connection to <ip> Failed to obtain WebVPN cookie When I run the same command with the same cert/key files on a Ubuntu 12.04 box, it works: openconnect \ --certificate=$VPN_CFG/alexander.crt \ --sslkey=$VPN_CFG/alexander.key \ --cafile=$VPN_CFG/Company_VPN_CA.crt \ --user=alexander --verbose <ip>:443 Attempting to connect to <ip>:443 Using certificate file $VPN_CFG/alexander.crt Extra cert from cafile: '/CN=Company AG VPN CA/O=Company AG/L=Zurich/ST=ZH/C=CH' SSL negotiation with <ip> Server certificate verify failed: self signed certificate Certificate from VPN server "<ip>" failed verification. Reason: self signed certificate Enter 'yes' to accept, 'no' to abort; anything else to view: yes Connected to HTTPS on <ip> GET https://<ip>/ […] Well… The error on the NAS is this: 5919:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1315: Any ideas, what's causing this? On Syno, I use OpenConnect 4.06. On Ubuntu, I just compiled and installed to a custom location OpenConnect 4.06 as well. Thanks, Alexander

• How powerful of a PC do you need to edit HD videos?

  - by Xeoncross

  I have a Core2Quad Q8200 (2.3GHz) with 4GB of RAM, a 512MB PCIe video card, and a SATA-2 HD. Yet it still isn't fast enough to edit 720i/p video in Sony Vegas or Adobe Premiere/Aftereffects. My RAM usage never peaks over 1.6GB, but my CPU cores make it to 95% quick! Right now the preview panes in all these programs lag to bad to actually work on the videos. I get to see 1-3 frames every second or two! So how fast do I have to go? At what point will my CPU be fast enough to actually edit these videos? I have to assume that regular people and their regular sub $2k computers can actually work with this footage. Another way to answer this is, how fast is the PC you used to edit videos? Update: I'ts worth noting that now that I have Adobe Pre/AF CS4 I am more interested in getting that working than my older Vegas 6. If you didn't have to re-run RAM preview every, single, time you made one change it would be my answer. But since I like to test many filters and effects before choosing one - I have to re-render a 1-sec section of footage over-and-over and it drives me nuts waiting. Perhaps a motherboard with Dual Xeon chips or something would be able to handle this. It would probably be as much as a dual-crossfire setup and would also speed up other applications.

• Folder Redirection Issues - Freezing, Strange Warnings

  - by JCardenas

  I have Folder Redirection set up in a test environment for a couple accounts. I have followed the instructions for setting up the folder security settings here, and I can confirm that folders are created automatically by the system with the correct security settings when a user logs in. The GPO has been configured to automatically move user files up to the redirected folders, and this is working properly. Problems start occurring when a Windows 7 PC is in use. It is rare, but Explorer will lock up when performing a file write operation (move/copy/save from application). This results in the entire system being unusable, with only a hard reset resolving it (Task Manager doesn't start, the "three finger salute" does nothing, apps stop working). The mouse functions, but clicks do nothing. The other issue is that occasionally when copying/creating/modifying files a dialog box will pop up with the message "You need permission to perform this action. You require permission from XYZ\cardenas to make changes to this folder." The folder that was created by copying an existing one has the correct security settings and lists me as the owner. My company will not be implementing Folder Redirection on XP, since we are making a "clean break" with implementing new technologies with the Windows 7 rollout, so this behavior has not been - nor will be - checked for in XP. Thanks in advance for your help!

• nginx+mysql5 loadtesting configuration strangeness

  - by genseric

  i am trying to setup a new server running on debian6 and trying to make it work smooth under load. i ve used a wordpress site as a test object, and tried the configurations on http://blitz.io. when i increase the mysql max_connections from 50 to 200 lots of timeouts start to occur. but on 50 , no timeouts and pretty well response times. nginx configuration is fine , i tuned the config so i dont see errors. so i presume it's related to the other configuration options of my.cnf . i read some about options but still cant find what max_connections problem is all about. btw, the server has 16gb of ram and a fine i7 cpu. here is the current my.cnf [client] port = 3306 socket = /var/run/mysqld/mysqld.sock [mysqld_safe] socket = /var/run/mysqld/mysqld.sock nice = 0 [mysqld] wait_timeout=60 connect_timeout=10 interactive_timeout=120 user = mysql pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp language = /usr/share/mysql/english skip-external-locking bind-address = 127.0.0.1 key_buffer = 384M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 20 myisam-recover = BACKUP max_connections = 50 table_cache = 1024 thread_concurrency = 8 query_cache_limit = 2M query_cache_size = 128M expire_logs_days = 10 max_binlog_size = 100M [mysqldump] quick quote-names max_allowed_packet = 16M [mysql] #no-auto-rehash # faster start of mysql but no tab completition [isamchk] key_buffer = 16M thanks in advance. i asked this question on SO but it's closed as off topic so i believe this is a SF question.

• executable in path, findable by which, yet cannot execute without fully qualifying path?

  - by Peeter Joot

  I've got a bizarre seeming shell issue, with a command in the $PATH that the shell (ksh, running on Linux) appears to cowardly refuse to invoke. Without fully qualifying the command, I get: # mycommand /bin/ksh: mycommand: not found [No such file or directory] but the file can be found by which: # which mycommand /home/me/admbin/mycommand I also explicitly see that directory in $PATH: # echo $PATH | tr : '\n' | grep adm /home/me/admbin The exe at that location seems normal: # file /home/me/admbin/mycommand /home/me/admbin/mycommand: setuid setgid ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for GNU/Linux 2.6.4, dynamically linked (uses shared libs), not stripped # ls -l mycommand -r-sr-s--- 1 me mygroup 97892 2012-04-11 18:01 mycommand and if I run it explicitly using a fully qualified path: # /home/me/admbin/mycommand I see the expected output. Something is definitely confusing the shell here, but I'm at a loss what it could be? EDIT: finding what looked like a similar question: Binary won't execute when run with a path. Eg >./program won't work but >program works fine I also tested for more than one such command in my $PATH, but find only one: # for i in `echo $PATH | tr : '\n'` ; do test -e $i/mycommand && echo $i/mycommand ; done /home/me/admbin/mycommand

• Create new folder for new sender name and move message into new folder

  - by Dave Jarvis

  Background I'd like to have Outlook 2010 automatically move e-mails into folders designated by the person's name. For example: Click Rules Click Manage Rules & Alerts Click New Rule Select "Move messages from someone to a folder" Click Next The following dialog is shown: Problem The next part usually looks as follows: Click people or public group Select the desired person Click specified Select the desired folder Question How would you automate those problematic manual tasks? Here's the logic for the new rule I'd like to create: Receive a new message. Extract the name of the sender. If it does not exist, create a new folder under Inbox Move the new message into the folder assigned to that person's name I think this will require a VBA macro.

• Unable to install PEM/pkcs12 created by gnutls to Cisco ASA

  - by ACiD GRiM

  I've been pulling some hair out trying to figure out why cisco devices don't like my certificates. My primary need is to get a trustpoint set up with CA,cert,key on the ASA for VPN systems, however I'm having the same issues on my IOS devices. I created a pkcs12 with openssl a few months ago that imported with no issues, but now that I'm getting ready to move this lab to production I'm using gnutls certtool as I found it adds alt_dns and ip_address fields properly to the certificate, (which cost me a few more hairs trying to get to work with openssl's ca tool) I'm including the current test certs below, don't worry I'm not using these in production ;) The maddening thing is that after I thought gnutls was generating certs incorrectly, I tried making a pkcs12 for a printserver and it imported with no issues. Here's my command flow for creating these certs: certtool --generate-privkey --disable-quick-random --outfile nn-ca.key certtool --generate-self-signed --load-privkey nn-ca.key --outfile nn-ca.crt certtool --generate-privkey --disable-quick-random --outfile nn-g0.key certtool --generate-certificate --load-privkey nn-g0.key --outfile nn-g0.crt --load-ca-privkey nn-ca.key --load-ca-certificate nn-ca.crt openssl pkcs12 -export -certfile nn-ca.crt -in nn-g0.crt -inkey nn-g0.key -out nn-g0.p12 openssl enc -base64 -in nn-g0.p12 -out nn-g0.base64.p12 The password for the attatched pkcs12 is "ciscohelp" without quotes. Thanks for any help TestCerts

• iSCSI, failover and XenServer

  - by jemmille

  I have an iSCSI fail over implementation setup so if one of my storage units fails the other takes over immediately (it also runs the NFS shares). When fail over occurs, volumes are exported, the IP is switched to the other machine and the targets are reconfigured. The fail over of the storage system itself works just fine. I use NexentaStor for my filer. When I do a test (manual) fail over of my storage the following occurs: Note: I run the admin VM's on NFS and customer based VM's on iSCSI All NFS based VM's remain up and working perfectly through the failover and after All VM 's running on iSCSI eventually report the following: An error about not being able to write to a particular block An error about journaling not working Then the file system goes RO To get the VM's working again I have to do the following: Force shutdown of the "broken" VM's. Detach the iSCSI SR Re-attach the iSCSI SR Boot the VM on a different server (5 in my pool) If I don't boot on a different server I get this error "Internal error: Failure("The VDI <uuid&gt; is already attached in RW mode; it can't be attached in RO mode!")" The only way I have found to fix that error is to reboot the entire server it was running on previously which is obviously a huge pain. Currently multipathing is NOT enabled (but can be and the same thing still occurs). I have edited much of the /etc/iscsid.conf file to work with the timeout settings but to no avail. In short, my storage fails over properly but XenServer does not keep the connection alive. As a thought, the error that shows up in #4 above might be the ultimate cause and fixing that would fix everything? Any help would be appreciated more than you know.

• How to deal with DELL support system?

  - by Nishant Kumar

  We have purchased a Dell Optiplex 9010 SSFV for our organization's work. Since the first installation two of the USB keyboard keys were not working properly. I had to press those keys two times simultaneously, on first time keys did not work and for for second time it printed two characters (as it were buffering first character.) Two keys that were not working properly: Hexangrave (Below the ESC key: `) Double Quotes (Left the enter key ") We registered our complaint with DELL and they suggested (with some hard to understand and weird ENGLISH accent) some test and tricks, such as switching to different ports, checking keyboard on different PC, and it worked well with diff. PC(with Windows 7 Home Premium installed). It was clear that it is an OS fault, hence they suggested to re-install OS. Problem began here, we have a project on the run and currently a video editing project setup on our system, so can't re-install system in hurry and also DELL persons were not providing any other solution such as updating keyboard driver, etc. Arguments I am a Software Engg. and don't think it is a feasible solution to re-install entire system for simple problems. This prob is coming since the fresh system installation, so I don't think it will solve the problem. Finally, I had to find solution myself and got it here, now I want to show my disappointment to dell persons or at least tell them that they should improve there support system to not advice to re-install entire system for that simple problems. Notes We have purchased 5 years NEXT business day support from DELL for around 8000 INR (Not for that kind of solutions from DELL). It is Dell India Support System. So can anyone tell me how to tackle dell support system officially, so that they will pay more attention in near future. Thanks

• How could Google Latitude find my exact PC location with no GPS or public wifi?

  - by Mike

  I found a similar question here but I still don't get it. You see, I live in a small town and every time I check my IP location via online services or speed test websites, my location appears to be my ISP server location (which in my case is 250 miles away). But when I tried Google latitude, it pinpointed my exact location within less than 100 meters! I use Windows Vista, Google Chrome, and when I got the message that "Google is trying to locate you", I agreed just to check what the result will be. It was scary, very scary! What I've come up after reading the above link is that Google have a kind of extensive WiFi database locations. That could be understandable with the case of public and open WiFis that are used with a lot of people. Some of them might be using applications that could gather location data and somehow this information ends up in giant Google databases. From those, Google could pinpoint a WiFi location based on its MAC address along with these bits of info that have been gathered via various sources. The issue here is that my WiFi is private, I don't even broadcast my WiFi name. So how on earth did Google find my exact PC location? Please break down the answer in layman's terms as possible.

• Deploying a Git server in a AWS linux instance

  - by Leroux

  I'm making a git server on my linux instance in AWS. I tried doing it using these instructions but in the end I always get stuck with a "Permission denied (publickey)" message. So here is my detailed steps, the client is my windows machine running mysysgit and the server is the AWS ubuntu instance : 1) I created user Git with a simple password. 2) Created the ssh directory in ~/.ssh 3) On the client I created ssh keys using ssh-keygen -t rsa -b 1024, they got dropped in my /Users/[Name]/.ssh directory, id_rsa and id_rsa.pub key pair was created. 4) Using notepad I copy pasted the text into newly created files on the server in the ~/.ssh directory of my Git user. ~/.ssh/id_rsa and **~/.ssh/id_rsa.pub** were copied. 5) On the server I made the authorized_hosts file using "cat id_rsa.pub authorized_hosts" (while inside the .ssh directory) 6) Now to test it, on my client machine I did ssh -v git@[ip.address] 7) Result : debug1: Host 'ip.address' is known and matches the RSA host key. debug1: Found key in /c/Users/[Name]/.ssh/known_hosts:1 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /c/Users/[Name]/.ssh/identity debug1: Trying private key: /c/Users/[Name]/.ssh/id_rsa debug1: Offering public key: /c/Users/[Name]/.ssh/id_dsa debug1: Authentications that can continue: publickey debug1: No more authentication methods to try.

• sql developer cannot establish connection to oracle db with listener running

  - by lostinthebits

  I am working from home and connected to my work's vpn. I have tried to connect to the work db with sql developer (the latest version and the previous version) on the following environments: mac os x 10.8.5 (with sql developer launched and installed directly on the iMac. sql developer launched and installed directly on a vm on same computer (guest Ubuntu 12.04 LTS) sql developer launched and installed directly on a vm on same computer (guest Windows 7.0 Professional) I get Status Failure Test Failed : IO Error - The Network Adapter could not establish the connection. I have read dba forums and googled and the most common suggestion is that the oracle listener is not up and running. I can conclusively say this is not the case because I have the option of using remote desktop and accessing the oracle db in question on my work computer. If the listener was down, according to my DBA, no one would be able to connect. My sysadmin and dba are stumped so I assume it is something unique to my home system. The reason I do not want to continue with the remote desktop workaround is because remote desktop has an annoying (infuriating often) lag.

• How to use Windows mini-dump files?

  - by ekaj

  I have a Mini-ITX Intel DH61AG mobo w/ an Intel i3 processor and 8GB of 1600MHz DDR3 RAM. Anyways, this computer has been crashing kind of frequently. It is not an OS problem, as I have used Ubuntu (and had kernel panics), Windows 7, and Windows 8 (BSODs aren't going to keep me from tinkering =p) Anyways, each of these OSes have had problems, so I ran a HDD check, and I know it is not a heat issue because I tested the processor for a few days when I first put the computer together. When I ran memtest86+, however, I got an error - so I did individual testing, and both chips came back good, did a really intense test with both of them again (took half a day), and no errors. So, I still think the problem could be RAM, but I am not sure - I tested it pretty extensively (might let it run all night again tonight)... which brings me to my point. Could someone explain to me (in simple terms if possible) how to READ the minidump files of Windows computers? I've tried before with a guide I found online, but failed miserably (can't remember guide, either =/). I'm fine with installing the software, I will probably need it sometime in the future as well. I have seen a few other posts on SU that just ask people to post minidump logs, but I feel as if that is too localized. Would someone be able to explain this? Note: If someone knows how to do this, but doesn't want to explain and is still willing to help me, this is the link for the minidump file =p Make sure to click

• Cannot upload files bigger than 8GB to Amazon S3 by multi-part upload due to broken pipe

  - by spencerho

  I implemented S3 multi-part upload, both high level and low level version, based on the sample code from http://docs.amazonwebservices.com/AmazonS3/latest/dev/index.html?HLuploadFileJava.html and http://docs.amazonwebservices.com/AmazonS3/latest/dev/index.html?llJavaUploadFile.html When I uploaded files of size less than 4 GB, the upload processes completed without any problem. When I uploaded a file of size 13 GB, the code started to show IO exception, broken pipes. After retries, it still failed. Here is the way to repeat the scenario. Take 1.1.7.1 release, create a new bucket in US standard region create a large EC2 instance as the client to upload file create a file of 13GB in size on the EC2 instance. run the sample code on either one of the high-level or low-level API S3 documentation pages from the EC2 instance test either one of the three part size: default part size (5 MB) or set the part size to 100,000,000 or 200,000,000 bytes. So far the problem shows up consistently. I attached here a tcpdump file for you to compare. In there, the host on the S3 side kept resetting the socket.

• openssl client authentication error: tlsv1 alert unknown ca: ... SSL alert number 48

  I've generated a certificate using openssl and place it on the client's machine, but when I try to connect to my server using that certificate, I error mentioned in the subject line back from my server. Here's what I've done. 1) I do a test connect using openssl to see what the acceptable client certificate CA names are for my server, I issue this command from my client machine to my server: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -prexit and part of what I get back is as follow: Acceptable client certificate CA names /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] 2) Here is what is in the apache configuration file on the server regarding SSL client authentication: SSLCACertificatePath /etc/apache2/certs SSLVerifyClient require SSLVerifyDepth 10 3) I generated a self-signed client certificate called "client.pem" using mypos.pem and mypos.key, so when I run this command: openssl x509 -in client.pem -noout -issuer -subject -serial here is what is returned: issuer= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] subject= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=mlR::mlR/[email protected] serial=0E (please note that mypos.pem is in /etc/apache2/certs/ and mypos.key is saved in /etc/apache2/certs/private/) 4) I put client.pem on the client machine, and on the client machine, I run the following command: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -status -cert client.pem and I get this error: CONNECTED(00000003) OCSP response: no response sent depth=1 /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] verify error:num=19:self signed certificate in certificate chain verify return:0 574:error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s3_pkt.c:1102:SSL alert number 48 574:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s23_lib.c:182: I'm really stumped as to what I've done wrong. I've searched quite a bit on this error and what I found is that people are saying the issuing CA of the client's certificate is not trusted by the server, yet when I look at the issuer of my client certificate, it matches to one of the accepted CA returned by my server. Can anyone help, please? Thank you in advance.

• Cisco ASA: Routing packets based on where the connections started from

  - by DrStalker

  We have a Cisco ASA 5505 (version 8.2(2)) with three interfaces: outside: IP address 11.11.11.11, this is the default route inside: IP address 10.1.1.1, this is the local subnet newlink: 22.22.22.22, this is a new internet connection. We need to move VPN users from the 11.11.11.11 address to the 22.22.22.22 address, and we're using SSH on the ASA as to test and sort out the routing. The problem we have is this: If we define a particular IP as being on a static route out the newlink interface then it can SSH to 22.22.22.22 fine. If we do not define a static route then the traffic hits the ASA, but the return traffic does not come back over newlink; presumably it gets sent over the outside interfcae as that is the default route. We can't define a static route for each remote endpoint because there are dialup VPN users, who obviously change IP a lot What we need to do is configure the ASA so if a connection comes in on the newlink interface then the outgoing packets for that go over the newlink interface, not the default route. With iptables this should be do-able by marking the connection and doing mark-routing, but what is the equivalent for a Cisco ASA?

• syslog-ng and nging logs to mysql

  - by Katafalkas

  So couple of days ago I asked how to log php and nginx logs to centralized MySQL database, and m0ntassar gave a perfect answer :) cheer ! The problem I am facing now is that I can not seem to get it working. syslog-ng version: # syslog-ng --version syslog-ng 3.2.5 This is my nginx log format: log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; syslog-ng source: source nginx { file( "/var/log/nginx/tg-test-3.access.log" follow_freq(1) flags(no-parse) ); }; syslog-ng destination: destination d_sql { sql(type(mysql) host("127.0.0.1") username("syslog") password("superpasswd") database("syslog") table("nginx") columns("remote_addr","remote_user","time_local","request","status","body_bytes_sent","http_ referer","http_user_agent","http_x_forwarded_for") values("$REMOTE_ADDR", "$REMOTE_USER", "$TIME_LOCAL", "$REQUEST", "$STATUS","$BODY_BYTES_SENT", "$HTTP_REFERER", "$HTTP_USER_AGENT", "$HTTP_X_FORWARDED_FOR")); }; MySQL table for testing purposes: CREATE TABLE `nginx` ( `remote_addr` varchar(100) DEFAULT NULL, `remote_user` varchar(100) DEFAULT NULL, `time` varchar(100) DEFAULT NULL, `request` varchar(100) DEFAULT NULL, `status` varchar(100) DEFAULT NULL, `body_bytes_sent` varchar(100) DEFAULT NULL, `http_referer` varchar(100) DEFAULT NULL, `http_user_agent` varchar(100) DEFAULT NULL, `http_x_forwarded_for` varchar(100) DEFAULT NULL, `time_local` text, `datetime` text, `host` text, `program` text, `pid` text, `message` text ) ENGINE=InnoDB DEFAULT CHARSET=latin1 Now first thing that goes wrong is when I restart syslog-ng: # /etc/init.d/syslog-ng restart Stopping syslog-ng: [ OK ] Starting syslog-ng: WARNING: You are using the default values for columns(), indexes() or values(), please specify these explicitly as the default will be dropped in the future; [ OK ] I have tried creating a file destination and it all works fine, and then I have tried replacing my destination with: destination d_sql { sql(type(mysql) host("127.0.0.1") username("syslog") password("kosmodromas") database("syslog") table("nginx") columns("datetime", "host", "program", "pid", "message") values("$R_DATE", "$HOST", "$PROGRAM", "$PID", "$MSGONLY") indexes("datetime", "host", "program", "pid", "message")); }; Which did work and it was writing stuff to mysql, The problem is that I want to write stuff to in exact format as nginx log format is. I assume that I am missing something really simple or I need to do some parsing between source and destination. Any help will be much appreciated :)

• How to improve Windows Server 2008 R2 to handle many connections?

  - by invisal

  It has been a few days so far that I am trying to figure how to solve this problem. First of all, I am running a website with an average daily page view of 350,000. Previously, all ads management (tracking click and impression that each ads has served) and content were served in a single server with the following spec: Server 1 OS: Windows 2008 R2 64-Bit CPU: Intel® Core™ i5 - 4 cores RAM: 8 GB Storage: 2 x 1 TB hard drives Bandwidth: 10 TB per month To improve our website speed, I decided to separate the ads management script to another dedicated server because we have more than 15 advertisers to 30 advertisers per each page. Server 2 OS: Windows 2008 R2 64-Bit CPU: Intel® Core™ i5 - 4 cores RAM: 4 GB Storage: 2 x 300 GB hard drives Bandwidth: 10 TB per month The Problem The problem is that Server 1 can handle both content and ads system. Now, that I take away the ads system and put it at Server 2. Server 2 can barely serve only ads system. Test First of all, I moved 75% of the ads to Server 2. And then, perform a ping to server: ping -t xxxxx. [I did the ping for 10 minutes and its following similar pattern as below] Reply from xxxxx bytes=32 time=290ms TTL=116 Reply from xxxxx bytes=32 time=289ms TTL=116 Reply from xxxxx bytes=32 time=320ms TTL=116 Reply from xxxxx bytes=32 time=286ms TTL=116 Reply from xxxxx bytes=32 time=286ms TTL=116 Reply from xxxxx bytes=32 time=348ms TTL=116 Reply from xxxxx bytes=32 time=284ms TTL=116 Then, I moved 100% of the ads to Server 2. Then, perform a ping to server again. [I did the ping for 10 minutes and its following similar pattern as below] Reply from xxxxx bytes=32 time=290ms TTL=116 Request timed out Reply from xxxxx bytes=32 time=320ms TTL=116 Reply from xxxxx bytes=32 time=286ms TTL=116 Request timed out Request timed out Reply from xxxxx bytes=32 time=284ms TTL=116 Attempts Increase MaxUserPort and TcpNumConnection Restart the server Increase IIS Max Instances and Instance MaxRequests Server Resource Only 10%-15% of the network connection is used Only 10%-15% of the CPU is used Only 25% of the memory is used

• problem booting crusty old windows XP

  - by Carson Myers

  I have an acer aspire laptop running Windows XP home. I believe I have some virus on it, I'm not sure--I mostly just run linux in a VM on it so I wasn't too worried. I'm not sure if that virus caused this problem. The laptop wasn't recognizing my USB hard drive for some reason so I decided to restart it. When it started up, it got past the memory test, past the boot screen, (but it paused right here on a blank screen for awhile) and flashed the desktop once (like it does just before the login screen) and then crashed. I got a quick BSOD and then it restarted. Then it tried to boot again, etc etc infinite loop of failure. Well, before trying safe mode, I disabled automatic restart on system crash so I could read the blue screen. There wasn't anything important on it, it said *** STOP: 0x00000000 (0xC0000000 0x,.... ) beginning physical memory dump physical memory dump complete That's not verbatim (obviously) but it didn't help me. so I booted in safe mode, and it stopped on the driver gagp30kx.sys and then restarted (and infinite loop of failure again). I burned a recovery CD and tried that. It loaded it, and I went into repair mode. I ran chkdsk and then disabled the AGP driver. Same thing on booting in safe mode except it stopped at mup.sys instead. I enabled the AGP driver again, and ran chkdsk again from the CD. It said it found problems but didn't say it fixed them. So I ran it a second time, and it said "performing additional checking or recovery" lots of times (I can't tell how many, they went above the screen top). I tried booting again and no luck. Every time I run chkdsk after trying to boot again it says it found and fixed more errors. I think it might be whatever driver is after the AGP driver, but I don't know what it is or how to find out. Can anyone help me fix this?

• How to plug power/reset buttons from case to motherboard leads?

  - by MaxMackie

  I have a motherboard I salvaged from a pre-assembled computer. Except now I'm trying to use it in my own custom build. The problem is, this motherboard doesn't have any documentation because it was never meant to be used by consumers (as far as I know). I need to plug in my case's power/reset/hdd-light plugs into the motherboard. I usually check the documentation of the board to see which leads go to what connector, but I have no documentation for the board. So, as I see it, I have two options: I find the documentation (I've emailed gateway customer service, but I'm unsure of how successful I'll be with that). I simply test the leads one after the other (can this cause damage if plugged into the wrong leads?) However, there might even be a standard for which leads do what action (I'm not sure about this). For reference, my motherboard's SN/MD (?) is: H57M01G1-1.1-8EKS3H Does anyone have any idea if I can find documentation or find another way to be sure if my connections are correct?

• 554 - Sending MTA’s poor reputation

  - by Phil Wilks

  I am running an email server on 77.245.64.44 and have recently started to have problems with remote delivery of emails sent using this server. Only about 5% of recipients are rejecting the emails, but they all share the following common message... Remote host said: 554 Your access to this mail system has been rejected due to the sending MTA's poor reputation. As far as I can tell my server is not on any blacklists, and it is set up correctly (the reverse DNS checks out and so on). I'm not even sure what the "Sending MTA" is, but I assume it's my server. If anyone could shed any light on this I'd really appreciate it! Here's the full bounce message... Could not deliver message to the following recipient(s): Failed Recipient: [email protected] Reason: Remote host said: 554 Your access to this mail system has been rejected due to the sending MTA's poor reputation.

• Data Protection Manager System Protection Backups Failing

  - by TrueDuality

  I'm just starting to setup DPM 2010 in a test environment with a Domain Controller and a File Server. Everything seem to be working fairly well and I can get all of my backup jobs to succeed except for the "Computer\System Protection" backups. Both servers are running fully up to date 64 bit Windows Server 2008 R2 Enterprise with Service Pack 1. The error that is being provided is: DPM cannot create a backup because Windows Server Backup (WSB) on the protected computer encountered an error (WSB Event ID: 517, WSB Error Code: 0x8078001D). (ID 30229 Details: Internal error code: 0x809909FB) This Microsoft Knowledge Base article describes the issue perfectly and provides a hotfix. I downloaded the hotfix, moved it onto the affected server, attempt to run it and receive the following error: The update is not applicable to your computer. I've verified that I have indeed downloaded the 64 bit version. According to this thread the hotfix got rolled into Service Pack 1, yet I'm still experiencing the issue. Both machines do have the Windows Server Backup feature installed. Can anybody point me in the right direction? What am I missing?
