• "Sticky button" configuration under X11/Ubuntu?

  - by John Whitley

  Is there a configuration or app that will enable Sticky-keys like functionality for a pointer button under X11? (On Ubuntu 9.10, FWIW.) To be clear, I'd like a single tap (down/up events) to be treated as a down event, and a following tap to be treated as an up event. Context: I have a trackball with a fourth button that I've mapped to act as horizontal/vertical scroll. This works great. It'd be even better if I didn't have to hold the button down when scrolling.

• mod_proxy failing as forward proxy in simple configuration

  - by Stabledog

  (On Mac OS X 10.6, Apache 2.2.11) Following the oft-repeated googled advice, I've set up mod_proxy on my Mac to act as a forward proxy for http requests. My httpd.conf contains this: <IfModule mod_proxy> ProxyRequests On ProxyVia On <Proxy *> Allow from all </Proxy> (Yes, I realize that's not ideal, but I'm behind a firewall trying to figure out why the thing doesn't work at all) So, when I point my browser's proxy settings to the local server (ip_address:80), here's what happens: I browse to http://www.cnn.com I see via sniffer that this is sent to Apache on the Mac Apache responds with its default home page ("It works!" is all this page says) So... Apache is not doing as expected -- it is not forwarding my browser's request out onto the Internet to cnn. Nothing in the logfile indicates an error or problem, and Apache returns a 200 header to the browser. Clearly there is some very basic configuration step I'm not understanding... but what?

• How to prevent parallel builds per build configuration across multiple Build Agents

  - by vanslly

  I have many build configurations in TeamCity, each servicing a large project. In the past if a build is kicked off the Build Agent could be busy for up to 20min! In order to improve throughput I installed a second Build Agent on the same machine such that if a build run is kicked off by say Build Agent 1 and it is busy for 20min and someone from another project makes a change then Build Agent 2 can do the build for the other project without needing to wait on the current build run to finish. All was well until two successive check-ins resulted in both Build Agents running a build for a single build configuration in parallel. Since some resources are shared, IIS directories & databases, I don't want a single build configuration to run on both Build Agents in parallel. How can I ensure a build isn't triggered if a build is currently running for that build configuration on a different build agent? One way seems to involve environmental variables and ensuring a 50/50 split by Build Agent in terms of build configuration compatibility, but that seems a little clunky.

• Virtualmin Configuration

  - by Allen

  I am trying to get Virtualmin setup and have reached a point where my noobish sysadmin skills aren't getting the job done. This is the message I get now when I try and refresh the configuration of Virtualmin. BIND DNS server is installed, and the system is configured to use it. However, the default master DNS server XXXXXX is not a fully qualified domain name. Sendmail is only accepting SMTP connections on the following ports : 127.0.0.1 port smtp. Email from other systems on the Internet will not be accepted. This can be changed in the Sendmail Mail Server module. Please advise what I need to do to get Sendmail configured properly. Thanks!

• Apache configuration: choose a site to display according to visitor's IP address

  - by user64294

  Hi all. I would like to set a special configuration in our apache web server. I would like to display sites to the users according their IP addresses. We plan to upgrade our web sites. During the upgrade we'll put a maintenance site: so all the users which will connect to our web sites will get this site. but in order to test the upgrade i need to set apache to let only my IP address to access to asked site. If my IP address is a.b.c.d and if i ask for test_dot_com i want to see it. but all other users, having a different IP address, should get the maintenane site even if they look for test_dot_com. Is there a way to do this? PS: sorry As i'm a new user i can't use more than one link. so test_dot_com = test.com Thank you.

• Unity Configuration and Same Assembly

  - by tyndall

  I'm currently getting an error trying to resolve my IDataAccess class. The value of the property 'type' cannot be parsed. The error is: Could not load file or assembly 'TestProject' or one of its dependencies. The system cannot find the file specified. (C:\Source\TestIoC\src\TestIoC\TestProject\bin\Debug\TestProject.vshost.exe.config line 14) This is inside a WPF Application project. What is the correct syntax to refer to the Assembly you are currently in? is there a way to do this? I know in a larger solution I would be pulling Types from seperate assemblies so this might not be an issue. But what is the right way to do this for a small self-contained test project. Note: I'm only interested in doing the XML config at this time, not the C# (in code) config. UPDATE: see all comments My XML config: <configuration> <configSections> <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration" /> </configSections> <unity> <typeAliases> <!-- Lifetime manager types --> <typeAlias alias="singleton" type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager, Microsoft.Practices.Unity" /> <typeAlias alias="external" type="Microsoft.Practices.Unity.ExternallyControlledLifetimeManager, Microsoft.Practices.Unity" /> <typeAlias alias="IDataAccess" type="TestProject.IDataAccess, TestProject" /> <typeAlias alias="DataAccess" type="TestProject.DataAccess, TestProject" /> </typeAliases> <containers> <container name="Services"> <types> <type type="IDataAccess" mapTo="DataAccess" /> </types> </container> </containers> </unity> </configuration>

• Postfix configuration: different outgoing hosts based on sender

  - by Joe

  I've seen a few answers to this on the web, but nothing definitive nor any good examples. I relay all my mail out through Postfix, currently everything sent to my ISP's mail server. However, there are a few users with gmail accounts or gmail-hosted accounts; I'd like to route their outgoing mail through Google's servers (since it will then appear in their Gmail sent folder). All email NOT from one of these senders should go out through the default relayhost. I believe I need to use the "sender_dependent_default_transport_maps" configuration within Postfix, but can't find a good example on what this setup looks like. Can anyone point me at a specific setup?

• Configuration Tuning for PostgreSQL 9.1 PostGIS 1.5 Ubuntu 12.04 Server

  - by Martin

  My server performance is poor. At times SSH, top, and other features or commands are very slow to respond, taking several seconds or more. A query that normally takes 5 minutes can sometimes take 30 minutes. The database is mostly being used to do a spatial query (grid and summarize) on approximately 500GB of stored data spread between 4 tables. Restarting the server works as a temporary fix, but cannot be used as a long term solution. Any suggestions for how to diagnose and solve my performance issues? Hardware and Configuration: 3.3 GHz Intel quad core i5 16 GB DDR3 RAM 6 TB software RAID 10 (6 x 2 TB drives) Ubuntu 12.04 64-bit Postgres 9.1 PostGIS 1.5

• How to stop ethernet interface in bridge configuration from obtaining IP address via DHCP

  - by user71061

  Hi! I'm trying to configure openvpn in bridging configuration. First step of doing this requires creating bridge interface (br0), bridging together physical ethernet interface (eth0) and logical tap0 interface. This can be done with simple script but I want to use less popular approach, configuring bridge interface entirely via /etc/network/interfaces file (on Debian linux). So I have removed all eth0 definitions form /etc/network/interfaces and replaced if with following br0 definition: auto br0 iface br0 inet static pre-up openvpn --mktun --dev tap0 address 10.0.0.1 netmask 255.255.255.0 bridge_ports eth0 tap0 post-down openvpn --rmtun --dev tap0 This works as I expected, but there is only one problem: interface eth0 is part of bridge interface br0 AND it also receive it's own IP address from my DHCP server (located on same LAN where eth0 is connected). My questions is: how to stop eth0 interface from obtaining it's own IP address? (It should only be part of br0 bridge).

• rsyslog appears to act on old configuration

  - by Jeff Lee

  I'm using a template to dynamically generate rsyslog filenames. I've made some changes from my original format, but rsyslog still appears to be using both the new template and the old after restarting. My filename template went from this: $template RemoteDailyLog,"/var/log/remote/%hostname%/%$year%/%$month%/%$day%.log" To this: $template RemoteDailyLog,"/var/log/remote/%hostname%/%fromhost-ip%/%$year%/%$month%/%$day%.log" I stopped rsyslogd using service rsyslog stop, deleted all of my log files using rm -rf /var/log/remote/*, and then restarted rsyslogd with service rsyslog start. The problem is rsyslog seems to be building folder structures of the type "/var/log/remote/%hostname%/%$year%/%$month%/%$day%.log" (i.e., without the remote IP), which no longer appears anywhere in my configuration. Is it possible that old log or config data have been cached somewhere and are being preserved through the server restart? This is creeping me out a little.

• Where in maven project's path should I put configuration files that are not considered resources

  - by Paralife

  I have a simple java maven project. One of my classes when executing needs to load an xml configuration file from the classpath. I dont want to package such xml file when producing the jar but I want to include a default xml file in a zip assemply under a conf subfolder and I also want this default xml to be available in the unit tests to test against it. As I see it there are 2 possible places of this default xml: src/main/resources/conf/default.xml src/main/conf/default.xml Both solutions demand special pom actions: In solution 1, I get the auto copy to target folder during build which means it is available in testing but I also get it in the produced jar which i dont want. In solution 2, I get the jar as I want it(free of the xml) but I manually have to copy the xml to the target folder to be available for testing. (I dont want to add src's subfolders in test classpath. I think it is bad practice). The question is what is the best solution of the two? If the correct is 2, what is the best way to copy it to target folder? Is there any other solution better and more common than those two? (I also read http://stackoverflow.com/questions/465001/where-should-i-put-application-configuration-files-for-a-maven-project but I would like to know the most "correct solution" from the "convention over configuration" point of view and this link provides some configuration type solutions but not any convention oriented. Maybe there isnt one but I ask anyway. Also the solutions provided include AntRun plugin and appAssembler plugin and I wonder if I could do it with out them.)

• Mirroring MySQL server with diffrent configuration

  - by HTF

  I have to migrate MySQL server to a different data centre so I would like to create another MySQL slave server in new DC and then promote it to a master later on. I previously used LVM snapshots and Percona Xtrabackup for this purpose but this time I've optimized MySQL configuration file that prevents me from using these methods. Old server (backup): innodb_log_file_size = 256M innodb_log_files_in_group = 3 New server (restore): innodb_log_file_size = 512M innodb_log_files_in_group = 2 The Xtrabackup script and LVM snapshots copy the whole directory structure so the MySQL server won't start because there is a different size for InnoDB logs. Is there any solution to avoid a downtime in this case? I can't use mysqldumps as there is around 8000 databases so I would have to take the server down for a couple of hours. I was also thinking to use the old settings with Xtrabackup and then change it once the new server is promoted to a master - less downtime but I'm not sure if this will work? Thank you Regards

• WSS "Cannot connect to the configuration database"

  - by Tim

  I have 64-bit WSS 3.0 installed on a 64-bit Windows 2003 Server. After installing WSS 3.0 I switched IIS to run in 32-bit emulation mode as we have some applications that require this. I'm getting a "Cannot connect to the configuration database" trying to get to the Central Admin page and wondered if: a. The setup I have won't work and I'm wasting my time trying to figure this out. or b. If anyone has any suggestions for resolving the database connection issue? The identity of the app pool that WSS runs under has all the required permissions in SQL so far as I can tell. Any help would be appreciated!

• Configuration tools for multiple monitors for X / Linux

  - by richard

  I have Ubuntu 10.04 running gnome and two monitors. I am wondering if a can get a better multi-monitor configuration tool. The one I have, gnome-display-properties, has too many problems, including: when I swapped my monitors over, the narrower one now on the left. There is a width calculation error, such that I have a virtual monitor the width of the wide-monitor on the narrow-monitor and part of the wide monitor. And a virtual narrow-monitor on the remainder of the wide-monitor. I would like: nobugs. to be able to select which is primary monitor. to have multiple configurations. configurations to be automatically selected based on which monitors are attached. configurations to be cycled (reliably) when display mode key is pressed. when a display is deactivated, for windows to migrate to remaining monitors. option to not change display resolution when mirroring, but to use side/top blanking bars to pad out screen.

• Relation between Apache and DNS configuration

  - by KayKay

  I configured my DNS (bind9) to accept every subdomain, using a wildcarded 'A' record : *.mydomain.tld. IN A xx.xx.xx.xx I configured Apache to serve some specific subdomains using virtual hosts : <VirtualHost *:80> ServerName sub1.mydomain.tld ServerAlias sub1.mydomain.tld JkMount / sub1JK JkMount /* sub1JK </VirtualHost> when I ping from a remote computer on a subdomain configured in apache I get a response. When I ping on a subdomain that is not configured in apache, the host is not found. I don't understand why apache configuration would affect DNS resolution like this? I would appreciate any information that helps me understand this. Thanks a lot.

• Installing Drupal: Database configuration problem.

  - by abelenky

  I am trying to install Drupal 6.16 on a clean website. I get through the "Verify Requirements" page easily. On the Database Configuration, I supply all the proper info, but "Save and Continue" returns me back to the same page, with no error message. I am unable to proceed past this point. I've verified my info with the ISP, including a non-local database host (under Advanced Options), and that the database user has full DBA rights. The lack of an error message is particularly frustrating. Do you have any ideas what the problem is, or how to pursue it and resolve it?

• Postfix configuration w.r.t. port 25

  - by Monkey Boson

  After a considerable amount of research, I have configured my postfix server to use dovecot to accept SMTPS connections over port 465 and everything works swimmingly. Unfortunately, I forgot that, unless I listen to port 25, I'm not going to receive any e-mail from the net. I'm hoping somebody knows off the top of their head how to open up port 25 on Postfix for anonymous users, but disallow relaying and any other bad things on that port. And to leave the port 465 the way it is. As to my current configuration, I changed the master.cf file: smtps inet n - n - - smtpd and the main.cf file: # Use our SSL certificates smtpd_tls_cert_file = .....cer smtpd_tls_key_file = .....key smtpd_tls_security_level = may # Use Dovecot for SASL authentication smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination Any help is appreciated!

• Network router and switch configuration

  - by gilly3

  Can I put a switch before my router in my home network? Here is a diagram of how I want to set up my network: ________________________________ ________________________________________ | | | | | Cable Access Panel | | Home Office | | _____________ ________ | | _____________ | | | | | | | | | | _________ | | | Cable Modem |--->| Switch |-------------->| Router |____| | | | |_____________| |________| | | |_____________| | Printer | | |______________________/____\____| | / | \ |_________| | ___/_ _\___ | _____/ ____|____ \_____ | | | | | | | | | | | | | | PC1 | | PC2 | | | PC3 | | Ext. HD | | PC4 | | |_____| |_____| | |_____| |_________| |_____| | |________________________________________| The reason I want to do this is because my router is also my wireless access point. My cable modem is located in the far corner of my home where my phone/tv/network access panel is. I'd rather keep the wireless access point in a more central location, but I'm not sure if DHCP will continue to work properly with that configuration. Edit: I'd like to continue to be able to share files and access my networked drive and printer from each computer in the house.

• CentOS-Like configuration of Vim on Ubuntu

  - by matejkramny

  Whenever I use a CentOS System, there's always a pleasant configuration of vim which mainly does the following: Remembering position of closed files Colour mode (!!!) Bash has colours There's lots more, just not something i can recall on the spot. Then, i go to ubuntu and its all black and white, no nice vim config etc. I have to use Ubuntu, and I hate ubuntu because of this. I know I can all configure it by myself, so my question is: How can I configure the Ubuntu system to behave (aesthetically) like CentOS? PS to future self: I will be stoned to death for asking such a question.
