  • Git push over http (using git-http-backend) and Apache is not working

    - by Ole_Brun
    I have desperately been trying to get push for git working through the "smart-http" mode using git-http-backend. However after many hours of testing and troubleshooting, I am still left with error: Cannot access URL http://localhost/git/hello.git/, return code 22 fatal: git-http-push failed` I am using latest versions of Ubuntu (12.04), Apache2 (2.2.22) and Git (1.7.9.5) and have followed different tutorials found on the Internet, like this one http://www.parallelsymmetry.com/howto/git.jsp. My VHost file currently looks like this: <VirtualHost *:80> SetEnv GIT_PROJECT_ROOT /var/www/git SetEnv GIT_HTTP_EXPORT_ALL SetEnv REMOTE_USER=$REDIRECT_REMOTE_USER DocumentRoot /var/www/git ScriptAliasMatch \ "(?x)^/(.*?)\.git/(HEAD | \ info/refs | \ objects/info/[^/]+ | \ git-(upload|receive)-pack)$" \ /usr/lib/git-core/git-http-backend/$1/$2 <Directory /var/www/git> Options +ExecCGI +SymLinksIfOwnerMatch -MultiViews AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> I have changed the ownership of the /var/www/git folder to root.www-data and for my test repositories I have enabled anonymous push by doing git config http.receivepack true. I have also tried with authenticated users but with the same outcome. The repositories were created using: sudo git init --bare --shared [repo-name] While looking at the apache2 access.log, it appears to me that WebDAV is trying to be used, and that git-http-backend is never fired: 127.0.0.1 - - [20/May/2012:23:04:53 +0200] "GET /git/hello.git/info/refs?service=git-receive-pack HTTP/1.1" 200 207 "-" "git/1.7.9.5" 127.0.0.1 - - [20/May/2012:23:04:53 +0200] "GET /git/hello.git/HEAD HTTP/1.1" 200 232 "-" "git/1.7.9.5" 127.0.0.1 - - [20/May/2012:23:04:53 +0200] "PROPFIND /git/hello.git/ HTTP/1.1" 405 563 "-" "git/1.7.9.5" What am I doing wrong? Is it an issue with the version of git and/or apache that I am using perhaps? BTW: I have read all the git http related questions on ServerFault and StackOverflow, and none of them provided me with a solution, so please don't mark this as duplicate.

  • exim4 redirect mail sent to *@domain1.example.com to *@domain2.example.com

    - by nightcoder
    Current situation: We have a VPS that hosts a website example.org. Exim is configured to work as a smarthost. All emails sent through exim are successfully relayed to another mail server (that is working on example.com). Goal: To forward mail sent to *@example.org to *@example.com, i.e. change the recipient's address from *@example.org to *@example.com. Problem: If I send email to address *@example.org, then it seems exim doesn't change the address, it still relays the message to another mail server but recipient is still *@example.org. Maybe the redirect is not applied for some reason. Configuration and logs: /etc/exim4/update-exim4.conf.conf: dc_eximconfig_configtype='smarthost' dc_other_hostnames='' dc_local_interfaces='' dc_readhost='example.org' dc_relay_domains='example.org' dc_minimaldns='false' dc_relay_nets='0.0.0.0/32' dc_smarthost='example.com::26' CFILEMODE='644' dc_use_split_config='false' dc_hide_mailname='true' dc_mailname_in_oh='true' dc_localdelivery='maildir_home' /etc/exim4/conf.d/router/999_exim4-config_redirect (created by me): domain_redirect: debug_print = "R: forward for $local_part@$domain" driver = redirect domains = example.org data = [email protected] (for now data is set to a specific address for simplicity and testing) exim log when sending email to [email protected] (should be redirected to [email protected]): 2012-03-20 19:40:07 1SA4ud-0005Dw-7k <= [email protected] U=www-data P=local S=657 2012-03-20 19:40:08 1SA4ud-0005Dw-7k => [email protected] R=smarthost T=remote_smtp_smarthost H=domain2.com [184.172.146.66] X=TLS1.0:RSA_AES_256_CBC_SHA1:32 DN="C=US,2.5.4.17=#13053737303932,ST=TX,L=Houston,STREET=Suite 400,STREET=11251 Northwest Freeway,O=HostGator.com,OU=HostGator.com,OU=Comodo PremiumSSL Wildcard,CN=*.hostgator.com" 2012-03-20 19:40:08 1SA4ud-0005Dw-7k Completed So, the address is not changed :( Please help!

  • Emails sent to outlook.com not being delivered

    - by imukcedup
    I'm having an issue that is a little strange. I have a cPanel webserver that I own and have root. I was testing out emailing and noticed some issues. When I send an email to outlook.com address the email sends ok but nothing is recieved at the outlook mailbox. I also dont get an 'email delivery failure notification' in any mailbox. 2014-06-12 09:53:47 SMTP connection from [127.0.0.1]:45334 (TCP/IP connection count = 1) 2014-06-12 09:53:47 1Wv5Rr-0003rA-2K <= [email protected] H=localhost (ourdomain.com) [127.0.0.1]:45334 P=esmtpa A=dovecot_login:joe S=667 [email protected] T="This is a test message" for [email protected] 2014-06-12 09:53:47 SMTP connection from localhost (ourdomain.com) [127.0.0.1]:45334 closed by QUIT 2014-06-12 09:53:50 cwd=/var/spool/MailScanner/incoming/1029481 5 args: /usr/sbin/exim -C /etc/exim_outgoing.conf -Mc 1Wv5Rr-0003rA-2K 2014-06-12 09:53:50 1Wv5Rr-0003rA-2K SMTP connection outbound 1402581230 1Wv5Rr-0003rA-2K ourdomain.com [email protected] 2014-06-12 09:53:50 1Wv5Rr-0003rA-2K => Test Account <[email protected]> R=archive_outgoing_email T=archiver_outgoing 2014-06-12 09:53:52 1Wv5Rr-0003rA-2K => [email protected] R=dkim_lookuphost T=dkim_remote_smtp H=mx1.hotmail.com [65.54.188.110] X=UNKNOWN:AES128-SHA256:128 C="250 <[email protected]> Queued mail for delivery" 2014-06-12 09:53:52 1Wv5Rr-0003rA-2K Completed I have checked the outlook.com's spam folders and its not in there either. This is a new IP address allocation from our ISP and there was a block on gmail addresses, so we know it was used for spam. But with gmail we got a notifaction of failure and I know outlook/microsoft also send out notification. Does anyone know what could be happening here? Thanks

  • Moving symlinks into a folder based on id3 tags.

    - by Reti
    I'm trying to get my music folder into something sensible. Right now, I have all my music stored in /home/foo so I have all of the albums soft linked to ~/music. I want the structure to be ~/music/<artist>/<album> I've got all of the symlinks into ~/music right now so I just need to get the symlinks into the proper structure. I'm trying to do this by delving into the symlinked album, getting the artist name with id3info. I can do this, but I can't seem to get it to work correctly. for i in $( find -L $i -name "*.mp3" -printf "%h\n") do echo "$i" #testing purposes #find its artist #the stuff after read file just cuts up id3info to get just the artist name #$artist = find -L $i -name "*.mp3" | read file; id3info $file | grep TPE | sed "s|.*: \(.*\)|\1|"|head -n1 #move it to correct artist folder #mv "$i" "$artist" done Now, it does find the correct folder, but every time there is a space in the dir name it makes it a newline. Here's a sample of what I'm trying to do $ ls DJ Exortius/ The Trance Mix 3 Wanderlust - DJ Exortius [TRANCE DEEP VOCAL TECH]@ I'm trying to mv The Trance Mix 3 Wanderlust - DJ Exortius [TRANCE DEEP VOCAL TECH]@ into the real directory DJ Exortius. DJ Exortius already exists, so it's just a matter of moving it into the correct directory that's based on the id3 tag of the mp3 inside. Thanks! PS: I've tried easytag, but when I restructure the album, it moves it from /home/foo which is not what I want.

  • Karmic iptables missing kernel moduyles on OpenVZ container

    - by luison
    After an unsuccessful p2v migration of my Ubuntu server to an OpenVZ container which I am stack with I thought I would give a try to a reinstall based on a clean OpenVZ template for Ubuntu 9.10 (from the OpenVZ wiki) When I try to load my iptables rules on the VM machine I've been getting errors which I believe are related to kernel modules not being loaded on the VM from the /vz/XXX.conf template model. I've been testing with a few post I've found but I was stack with the error: WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. FATAL: Could not load /lib/modules/2.6.24-10-pve/modules.dep: No such file or directory iptables-restore v1.4.4: iptables-restore: unable to initialize table 'raw' Error occurred at line: 2 Try `iptables-restore -h' or 'iptables-restore --help' for more information. I read about the template not loading all iptables modules so I added modules to the XXX.conf of the VZ virtual machine like this: IPTABLES="ip_tables iptable_filter iptable_mangle ipt_limit ipt_multiport ipt_tos ipt_TOS ipt_REJECT ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_LOG ipt_length ip_conntrack ip_conntrack_ftp ip_conntrack_irc ipt_conntrack ipt_state ipt_helper iptable_nat ip_nat_ftp ip_nat_irc" As the error remained I read that I should build dependencies again on the virtual machine: depmod -a but this returned an error: WARNING: Couldn't open directory /lib/modules/2.6.24-10-pve: No such file or directory FATAL: Could not open /lib/modules/2.6.24-10-pve/modules.dep.temp for writing: No such file or directory So I read again about creating the directory empty and redoing "depmod -a" it. I now don't get the dependancies error but get this and I don't have a clue how to proceed: WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. FATAL: Module ip_tables not found. iptables-restore v1.4.4: iptables-restore: unable to initialize table 'raw' Error occurred at line: 2 Try `iptables-restore -h' or 'iptables-restore --help' for more information. I understand that iptables rules have to be different on the VM machine and perhaps some of the rules we are trying to apply (from our physical server) are not compatible but these are just source IP and destination port checks that I would like to be able to have available . I've heard that on the CentOS template there are no issues with this, so I understand is to do with VM config. Any help would be greatly appreciated.

  • When running PowerShell script as a scheduled task some Exchange 2010 database properties are null

    - by barophobia
    Hello, I've written a script that intends to retrieve the DatabaseSize of a database from Exchange 2010. I created a new AD user for this script to run under as a scheduled task. I gave this user admin rights to the Exchange Organization (as a last resort during my testing) and local admin rights on the Exchange machine. When I run this script manually by starting powershell (with runas /noprofile /user:domain\user powershell) everything works fine. All the database properties are available. When I run the script as a scheduled task a lot of the properties are null including the one I want: DatabaseSize. I've also tried running the script as the domain admin account with the same results. There must be something different in the two contexts but I can't figure out what it is. My script: Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010 Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "Starting script" $databases = get-mailboxdatabase -status if($databases -ne $null) { Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "Object created" $databasesize_text = $databases.databasesize.tomb().tostring() if($databasesize_text -ne $null) { $output = "echo "+$databasesize_text+":ok" Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "Path check" if(test-path "\\mon-01\prtgsensors\EXE\") { Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "Path valid" Set-Content \\mon-01\prtgsensors\EXE\ex-05_db_size.bat -value $output } Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "Exiting program" } else { Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "databasesize_text is empty. nothing to do" } } else { Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "object not created. nothing to do" } exit 0

  • Current wisdom on SQL Server and Hyperthreading?

    - by BradC
    Lots of articles out there (see Slava Oks's original SQL 2000 article and Kevin Kline's SQL 2005 update) recommend disabling hyperthreading on SQL servers, or at least testing your specific workload before enabling it on your servers. This issue is gradually becoming less relevant as true multi-core processors replace hyperthreaded ones, but what's the current wisdom on this issue? Does this advice change any with SQL 2005 64-bit, or SQL 2008, or Windows Server 2008? Ideally, this should be tested in advance in a staging environment, but what about for servers that have already made it into production with HT enabled? How can I tell if performance issues we're experiencing might be related to HT? Is there some specific combination of perfmon counters that might point me in that direction, as opposed to all the other things I normally pursue when working on improving SQL performance? Edit: This is especially attractive because of the potential for an across the board improvement for some of my high-cpu servers, but the client is going to want to see something concrete that helps me identify which servers really could benefit from disabling hyperthreading. Of course, conventional performance troubleshooting is ongoing, but sometimes any little bit helps.

  • Exchange 2003 IMAP not working for some users

    - by John Gardeniers
    We normally don't have a need for IMAP connections from outside the company network but in order to allow a one user to use IMAP on a portable device I've turned it on and opened port 993 on the firewall. When the user in question was unable to get connected I tested this using Outlook remotely. Start by creating a new IMAP account in Outlook using a test account. No problems, it worked perfectly. Now try the same thing using the account of the user who actually needs to connect and it's a no-go. Outlook simply keeps prompting for logon credentials. Next I tried using my own account and that too failed. Testing with a couple of other accounts worked perfectly. Interestingly enough, with my own account I've used IMAP on a MAC before (internally) without a problem and I'm not aware of anything that has changed which could affect IMAP on my account. Checking the user settings in ADUC showed that all accounts have the same Exchange protocol settings. Specifically, IMAP is enabled. A check of the event logs on the server reveals no entries for the connection attempts, making this kind of difficult to debug. Has anyone here encountered such a situation and, even more importantly, what caused it?

  • Windows 7 network performance tuning for LAN

    - by Hubert Kario
    I want to tune Windows 7 TCP stack for speed in a LAN environment. Bit of background info: I've got a Citrix XenServer set up with Windows 2008R2, Windows 7 and Debian Lenny with Citrix kernel, Windows machines have Tools installed the iperf server process is running on different host, also Debian Lenny. The servers are otherwise idle, tests were repeated few times to confirm results. While testing with iperf 2008R2 can achieve around 600-700Mbps with no tuning what so ever but I can't find any guide or set of parameters that will make Windows 7 achieve anything over 150Mbps with no change in TCP window size using -w parameter to iperf. I tried using netsh autotuining to disabled, experimental, normal and highlyrestricted - no change. Changing congestionprovider doesn't do anything, just as rss and chimney. Setting all the available settings to same values as on Windows 2008R2 host doesn't help. To summarize: Windows 2008R2 default settings: 600-700Mbps Debian, default settings: 600Mbps Windows 7 default settings: 120Mbps Windows 7 default, iperf -w 65536: 400-500Mbps While the missing 400Mbps in performance I blame on crappy Realtek NIC in the XenServer host (I can do ~980Mbps from my laptop to the iperf server) it doesn't explain why Windows 7 can't achieve good performance without manually tuning window size at the application level. So, how to tune Windows 7?

  • SSH client and Command Prompt replacements Windows look-and-feel

    - by Oddthinking
    The Problem I've worked exclusively in Windows. I can handle that. I've worked exclusively in DOS (a long time ago!). I can handle that. I've worked exclusively in Unix. I can handle that. Right now, I am developing a command-line (python) application on a Windows machine, testing it in a DOS box (i.e. Windows' Command prompt), and then deploying it to Linux, and running it with PuTTY. I cannot handle that. My productivity drops dramatically when CTRL-C cuts in one window (Windows) and kills the process in another (DOS, Linux). My productivity drops dramatically when Enter copies the selection in one window (DOS), and deletes the selection in another (Windows), and runs the current half-edited command in the third (PuTTY). My productivity drops dramatically when I cannot hit Undo, Home or End. The Solution I am Seeking An SSH/Bash command-line client that runs on Windows and, to the extent possible, uses all the standard Windows shortcuts (Cut, Copy, Paste, Undo, Home, End, Insert, Shift-Arrows, etc.) work on a bash command line. Bonus points if it puts the cursor between letters, rather than on them. Plus, an equivalent DOS command-line drop-in that runs on Windows, and provides the same interface. I appreciate there may need to be special buttons to actually transfer CTRL codes (like CTRL-C) through in the cases I need them. I suspect the SSH client will need to be specific to a shell (so it knows when it is at the command prompt, and when it is inside a running app.) I know there are many SSH clients, but I am looking for advice for a particular need. PuTTY feels like an escape route for Unix programmers stuck on Windows. I am the opposite. Can anyone recommend one (or maybe a combination of an SSH client and an Command-Line replacement)?

  • DansGuardian/Squid Traffic doesn't get back to user

    - by DKNUCKLES
    I've purchased a Squid appliance that I'm attempting to implement, however the lack of documentation has left me a bit high and dry. Forgive me if this is a silly question, but this is my first attempt at implementing Squid. From what I can ascertain from the documentation (or lack thereof), the users connect to DansGuardian first at port 8080 where the filtering is done, at which point it forwards it to the Squid appliance at port 3128. The traffic is then sent to the internet. The setup I have is as follows Gateway (MikroTik router) : 192.168.88.1 Squid/DansGuardian :192.168.88.100 Client : 192.168.88.238 Client --- Gateway --- Proxy --- Internet I have set up a simple NAT rule to forward all traffic from the client machine (for testing purposes) to go to the DansGuardian. The traffic seems to get there, although I see a lot of SYN_RECV w/ a netstat -antp command on the virtual appliance machine. From this I gather that the traffic is NOT being routed back to the client machine. Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN - tcp 0 0 192.168.88.100:8080 192.168.88.238:55786 SYN_RECV - tcp 0 0 192.168.88.100:8080 192.168.88.238:55787 SYN_RECV - tcp 0 0 192.168.88.100:8080 192.168.88.238:55785 SYN_RECV - tcp 0 0 192.168.88.100:8080 192.168.88.238:55788 SYN_RECV - tcp 0 0 0.0.0.0:10000 0.0.0.0:* LISTEN - tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN - Is this a routing issue or an issue with the Squid Appliance?

  • SQL Server 2005 SP3 on Windows 7 - No Management Studio

    I've been trying for a day and a half now to get SQL Server 2005, DEV edition, to work on Windows 7, 64 bit prof. I install from the disk, then run SP 3. I get a failure on the Client Components section of the Installation Progress along with this vague message - Product : Client Components Product Version (Previous): 1399 Product Version (Final) : Status : Failure Log File : C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\LOG\Hotfix\SQLTools9_Hotfix_KB955706_sqlrun_tools.msp.log Error Number : 1712 Error Description : MSP Error: 1712 One or more of the files required to restore your computer to its previous state could not be found.

  • Missing Data on VMWare Virtual Disk

    - by Lachlan McDonald
    Evening all, I've got a considerable problem I'm hoping to get some resolution on. I had two VMWare 6.5 virtual machines, one running Ubuntu 9.10 and the other Ubuntu 10.04. I used 9.10 as a testing server, so I could install a LAMP environment to prepare some code. Over the months I took a number of snapshots of this VM just in case something went wrong, and did a full copy of the entire VM a month ago. I created the 10.04 VM when Lucid Lynx launched so I could continue development on a fresh install. To get the files over, I simply added the 9.10 virtual disk into the 10.04 VM, grabbed some of the files I needed, and dismounted it. Unknown to me at the time, the changes to the 9.04 virtual disk meant that I could no longer boot it with the 9.10 VM. I'd always get the "The parent virtual disk has been modified since the child was created." error. I decided this was a good time to backup all the critical files, but now whenever I open the 9.04 disk to get the data it isn't in the same state as it was earlier. My question is; is it possible when I'm mounting the virtual disk that I'm not seeing the most recent snapshot, or in my blundering, have I lost the virtual disk. Cheers

  • Adding 2008 Server to 2008 Domain

    - by Phillip
    Hello, I'm trying to create a lab for testing before I deploy solutions, I'm no experienced IT Administrator, and therefore I come here for help. I'm running 2 Virtual Servers on the same machine on a local connection between those two. They'are able to ping each other. Their names is TSDATA1 and TSDATA2 where TSDATA1 is the Domain Controller. I am able to ping between those two, on both "ping TSDATA1" and "ping 10.0.0.1" which is the IP address of TSDATA1. The IP address of TSDATA2 is 10.0.0.2. I'm trying to join the domain with TSDATA2 both I'm getting this error when trying: Note: This information is intended for a network administrator. If you are not your network's administrator, notify the administrator that you received this information, which has been recorded in the file C:\Windows\debug\dcdiag.txt. The following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller for domain tsdata.local: The error was: "DNS name does not exist."

  • Exchange 2003 ActiveSync problem

    - by colemanm
    We're having problems getting iPhones to sync properly with SBS 2003 Exchange. When you add a new Exchange ActiveSync account on an iPhone and enter all the pertinent information, it shows a "Verifying Exchange account info" message for a minute or so, then says everything's verified and asks what you want to sync, Mail, Contacts, Calendars... so it looks like it's working. However, when you go to the Mail app and select the Exchange email account, it just shows an "Inbox" folder with nothing in it. When you try refreshing, it attempts for a second, then says "Last Updated" with a timestamp, as if it worked, but there's no mail and no error message/feedback at all. I think I've narrowed it down to some sort of certificate issue, but I'm having trouble finding out where to go from here... I ran MS's Exchange connectivity testing tool with these results: Our cert was purchased from Network Solutions, and I'd already added it to the IIS Default Website for OWA purposes. But this report makes it look like the cert is somehow problematic. I don't know what to do now... Here's a shot of the cert details, just in case:

  • Active directory Kerberos OSX problems

    - by Temotodochi
    I'll try to keep this short, but informative. I'm currently unable to bind OSX lion (10.7.4) machines to our AD. OSX kerberos (heimdal) is unable to locate the KDC service. However i can bind linux & windows machines to the AD without any problems in the same network AD controls the domain DNS and all the relevant _kerberos._tcp.x.domain.com and _kpasswd SRV DNS records are there and resolve fine when tried from OSX machines. Defined ports are open for service and manually accessible from OSX. When i try kinit in the OSX, i can get the first auth through (wrong passwords fail instantly), but when supplied with correct password, kinit fails after some waiting with "unable to reach KDC". All machines run NTP and have correct time. During testing, network is not firewalled between the machines Linux and windows machines have no problems whatsoever I have tried with and without /etc/krb5.conf - OSX by default does not need it in the krb5.conf i used a working config from one of our linux machines. dsconfigad fails with simple "connection failed to the directory server" I'm a bit baffled with this. OSX is like the KDC is nowhere to be found and at the same time my test machines with windows 7 and some linux (centos 6 & debian 6) machines have no problems whatsoever. Same network, same configurations. I'm missing some vital piece of configuration somewhere, and i can't find out what it is.

  • I am looking for a tool to measure or detect "unresponsiveness" of a desktop PC

    - by Tom H
    I have a client that provides some server systems to a hospital, and a support ticket was raised that the desktop application was hanging waiting for the server. We did some extensive testing and its pretty clear that the server is responsive, and the network is fine, and that the problem is on the client end. (no requests are received during the hang etc...) We take a look at the desktop machines and they should be fine, so we raise tickets with the software vendor who says that it must be the hardware, the hardware company says that it is the software, etc etc Anyway, so talking to the nurses, they say that these machines often "hang" for 30 seconds at a time, and sometimes during important moments where they need to get data for a patient who is unwell, such as charts and status. So I want to stick a client on these machines that would be able to detect arbitrary "unresponsiveness" of the keyboard/mouse and log that for analysis later. Obviously I am wary to suggest some application that takes resources and makes the problem even worse, so I would interested to see any tools that would detect these (is it correct to say that the keyboard interrupts are being discarded?) scenarios by looking for the OS discarding the interrupts, or whatever is appropriate here. so go on then serverfault, here is your chance to save a life.... ;-) Edit: I am starting to think that some of the tools associated with real time systems might be appropriate, at least as a diagnostic.

  • Performance Test and TCP tuning

    - by Mithir
    We are in the process of performance testing an application which receives tcp requests converts them to soap requests (WCF-httpBinding) which other services work on. The server is Windows Server 2008 R2. The TCP requests are received by TcpListener instance (.NET C#). There are 3 http-binded WCF services running on the same server. We have built a performance test client which goal is to simulate multiple concurrent requests(each request has to be different and recognizable by the application). We built a test running 150 requests that run on the same time (by 150 different threads), and we noticed straight away that some requests get the TCP connection slowly, but once they get it, they act fast. A single request writes twice on the same connection- request and an application ack. Although a single request+ack can take about 150ms, the 150 test takes about 7 seconds. The Problem When we try to run this test from 2 different computers we lose requests. some clients requests are getting no connection was made because the target machine actively refused it So I got here and got convinced it was because of the backlog. I changed the TcpListener parameters and did the registry AFD backlog changes written here but it still didn't work, so I inserted all of the TCP tuning suggested plus some netsh commands which were recommended, but still no change, we still get that error. Is there anything else I need to know? Are there any other solutions?

  • VPN being blocked somewhere between either my BT2700HGV and DLink DFL-210

    - by Dom
    Hi, For some time I have been unable to get VPN working through my set up. I have a BT2700HGV Router (2 Wire Model) and as a firewall I have the Dlink DFL-210. You can't turn the firewall completely off on the BT2700HGV so I have it set to DMZplus mode for the Firewall. In theory this should then allow the VPN ports through. On the Firewall I have a series of rules set up and one is the pptp-allow rule which should allow access on the correct ports also. When I try to connect via VPN however the client machine gets an error 809. If I check the log on the Dlink firewall, I see this record: http://dl.dropbox.com/u/1041315/packetdrop.PNG The laptop I am testing the vpn with is connected directly to the BT2700HGV router and I am trying to VPN from it onto 81.138.86.217. I can't work out whether I have some sort of problem in the set up of the rules on my firewall or if the BT router (even though it's in DMZplus mode) is still blocking port 1723. I read somewhere that there where problems because BTs Openzone held onto this port for some reason. Any help would be greatly appreciated. If you need further screen shots or information then please let me know. I wasn't able to create new tags for the router and firewall name or insert the picture in as I am new to the forum. Dom :-)

  • Object Not found - Apache Rewrite issue

    - by Chris J. Lee
    I'm pretty new to setting up apache locally with xampp. I'm trying to develop locally with xampp (Ubuntu 11.04) linux 1.7.4 for a Drupal Site. I've actually git pulled an exact copy of this drupal site from another testing server hosted at MediaTemple. Issue I'll visit my local development environment virtualhost (http://bbk.loc) and the front page renders correctly with no errors from drupal or apache. The issue is the subsequent pages don't return an "Object not found" Error from apache. What is more bizarre is when I add various query strings and the pages are found (like http://bbk.loc?p=user). VHost file NameVirtualHost bbk.loc:* <Directory "/home/chris/workspace/bbk/html"> Options Indexes Includes execCGI AllowOverride None Order Allow,Deny Allow From All </Directory> <VirtualHost bbk.loc> DocumentRoot /home/chris/workspace/bbk/html ServerName bbk.loc ErrorLog logs/bbk.error </VirtualHost> BBK.error Error Log File: [Mon Jun 27 10:08:58 2011] [error] [client 127.0.0.1] File does not exist: /home/chris/workspace/bbk/html/node, referer: http://bbk.loc/ [Mon Jun 27 10:21:48 2011] [error] [client 127.0.0.1] File does not exist: /home/chris/workspace/bbk/html/sites/all/themes/bbk/logo.png, referer: http://bbk.$ [Mon Jun 27 10:21:51 2011] [error] [client 127.0.0.1] File does not exist: /home/chris/workspace/bbk/html/node, referer: http://bbk.loc/ Actions I've taken: Move Rewrite module loading to load before cache module http://drupal.org/node/43545 Verify modrewrite works with .htaccess file Any ideas why mod_rewrite might not be working?

  • EFI vs MBR - Installing Windows Server 2008 R2 or 2012 on 8TB

    - by Riaan de Lange
    I'm having some difficulty installing Windows Server 2008 R2 and Windows Server 2012 on an Intel Server platform. The server specs is as follows: Intel Grizzly Pass Server System - R2308GZ4GC 2x Intel Xeon 2620 - 2.0 GHZ - BX80621E52620 132 GB of Memory REG-DIMM - TS1GKR72V6H 4x Seagate Constellation ES 2TB 3.5" 7200rpm 6GB/S - ST32000645NS Intel Big Laurel 4CH 6G SAS RAID 512MB - RS2BL040 On the Intel RAID Controller Setup, I have setup the HDD to be in RAID-0 - for testing purposes. (Ultimately configured in RAID-5) So, the total size of HDD space I can use is 7.6 TB something... When I install the Server OS's, they don't seem to go beyond 2 TB (1.76 TB) I have read up on EFI and UEFI boot, and this seems to work in 2012, but I could not install any drivers for the motherboard... So, I also tried EFI for 2008R2, and this worked while installing the OS, it did not however work with the Windows Boot Manager option in the BIOS. It kept on freezing once it tries to load the partition. My idea was to allocate the complete 8 TB for the OS, and load a few VM's on there. I have now started with a new approach where I'll have a 256 GB OS Partition, and a secondary 7.5 TB Data partition. Oh, and I also did a diskpart - convert disk to gpt whilst installing 2008R2. The whole disk was accessible, 7.6TB Can anyone please clarify that EFI/UEFI is meant for larger boot volumes? Bigger than 2TB. If I were to have an ideal situation where my OS is run on a SSD, 256GB, and I can attach the 8 TB drives as normal disk to the OS? I'm I correct in saying that if I wanted to boot from a 8TB partition, I would need to force the BIOS to boot from EFI? The limit for MBR is 2 TB as far as I know now... *FYI: The motherboard is EFI-ready

  • Cisco router not receiving OSPF updates

    - by WebDevHobo
    Or at least, that's what I think is happening. There doesn't appear to be a debug command for this, or to see if something is in the routing table. I'm testing out this setup in Packet Tracer. I have 3 routers and a webserver From left to right, you have: Webserver - Router1 - Router2 - Router3 Router1 and Router2 can succesfully ping WebServer. Router3 cannot. Router2 has a default gateway set, to send all not-recognized data through its serial interface to Router1. Like this: ip route 0.0.0.0 0.0.0.0 Serial 0/0/1 Serial 0/0/1 being the connection to Router1 Router2 and Router3 have OSPF configured. From their "show run": Router2: router ospf 1 log-adjacency-changes passive-interface Serial0/0/1 network 10.1.1.0 0.0.0.3 area 0 default-information originate ! Router3: router ospf 1 log-adjacency-changes network 10.1.1.0 0.0.0.3 area 0 passive-interface FastEthernet0/0 ! I was under the assumption that setting default-information originate on Router2 would give Router3 the needed information. What's going wrong here? The interfaces are up. Ip addresses are with mask-range, clock rate is set at correct end. I don't know what else to check.

  • passing on command line options in bash

    - by bryan
    I have a question. I have a script, a kind of long script written in bash aprox. 370 lines. That has several functions and in those functions the user has to enter information which is then stored in files. ( This is suppose to represent a MySQL database, with the functions INSERT, UPDATE, SELECT, SELECT where x=y.) I created this myself in bash, now the only thing that rests me is that I need to be able to pass arguments on the command line to the script, that will do the same as the script does. I know that bash has positional parameters such as $1 $2 $3 $* $@ $0 ( refers to the name of the script) etc. I know how I can use these parameters in a simple if function. This is not enough for my script. I basicly need to do the same thing that the script does, but then from the command line. I have been struggling with this for a couple of days now and I cannot think of a way to get it to work. Maybe someone here can help me with this? If you want to have the script. That can be possible, but I don't think I can paste it in here... EDIT: Link to script, http://pastebin.com/Hd5VsDv2 Note, I am a beginner in bash scripting. EDIT: This is in reply to Answer 1. As I said I hope I can just replace the if [ "$1" = "one" ] ; then echo "found one" to if [ "$1" = "one" ] ; then echo SELECT where SELECT is the function I previously had in my script(above) http://pastebin.com/VFMkBL6g LINK to testing script

  • Nginx Slower than Apache??

    - by ichilton
    Hi, I've just setup 2x identical Rackspace Cloud instances and am doing some comparisons and benchmarks to compare Apache and Nginx. I'm testing with a 3.4k png file and initially 512MB server instances but have now moved to 1024MB server instances. I'm very surprised to see that whatever I try, Apache seems to consistently outperform Nginx....what am I doing wrong? Nginx: Server Software: nginx/0.8.54 Server Port: 80 Document Length: 3400 bytes Concurrency Level: 100 Time taken for tests: 2.320 seconds Complete requests: 1000 Failed requests: 0 Write errors: 0 Total transferred: 3612000 bytes HTML transferred: 3400000 bytes Requests per second: 431.01 [#/sec] (mean) Time per request: 232.014 [ms] (mean) Time per request: 2.320 [ms] (mean, across all concurrent requests) Transfer rate: 1520.31 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 11 15.7 3 120 Processing: 1 35 76.9 20 1674 Waiting: 1 31 73.0 19 1674 Total: 1 46 79.1 21 1693 Percentage of the requests served within a certain time (ms) 50% 21 66% 39 75% 40 80% 40 90% 98 95% 136 98% 269 99% 334 100% 1693 (longest request) And Apache: Server Software: Apache/2.2.16 Server Port: 80 Document Length: 3400 bytes Concurrency Level: 100 Time taken for tests: 1.346 seconds Complete requests: 1000 Failed requests: 0 Write errors: 0 Total transferred: 3647000 bytes HTML transferred: 3400000 bytes Requests per second: 742.90 [#/sec] (mean) Time per request: 134.608 [ms] (mean) Time per request: 1.346 [ms] (mean, across all concurrent requests) Transfer rate: 2645.85 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 1 3.7 0 27 Processing: 0 3 6.2 1 29 Waiting: 0 2 5.0 1 29 Total: 1 4 7.0 1 29 Percentage of the requests served within a certain time (ms) 50% 1 66% 1 75% 1 80% 1 90% 17 95% 19 98% 26 99% 27 100% 29 (longest request) I'm currently using worker_processes 4; and worker_connections 1024; but i've tried and benchmarked different values and see the same behaviour on all - I just can't get it to perform as well as Apache and from what i've read previously, i'm shocked about this! Can anyone give any advice? Thanks, Ian

  • SATA Blu-Ray drive not detected via USB adapter

    - by LTR
    I'm using an SATA blu-ray drive (Lite-On IHOS104), connected via a USB adapter to my Windows 7 (32-bit) notebook. The first time I plugged the adapter in, it worked perfectly. The drive appeared in Explorer, and my player software was able to play an encrypted Blu-Ray disc just fine. After the first reboot, it never worked again. Now it shows up as "removable media" with a size of 0 bytes, irregardless of whether a disk is inserted or not. The drive does not show up under the green "eject USB device" icon in the taskbar. The adapter is powered using a separate power adapter. I have tried: disconnecting all other USB devices testing with a DVD instead of a Blu-Ray disc letting Windows search for updated drivers for the drive - there are none using the same drive and adapter on another Win7 (but x64) computer. They work perfectly. using other USB ports on the same notebook - tried them all. using a different SATA/USB-adapter What else can I do to diagnose this problem?
