• IIS7 can't read web.config on shared Mac filesystem

  - by RobG

  I'm running a VirtualBox virtualized Windows 2008 Server on my Mac, just finished setting it up today. On it, I have SQL Server 2008, IIS and ColdFusion 9. I want to serve websites from my Mac filesystem (for development purposes). So I created a new website in IIS and pointed it at the appropriate path using a UNC path: \vboxsvr\rob\Sites\testsite, which contains the ColdFusion code and a web.config file. When I attempt to modify the file at all, or view the site in a web browser, I get an error: HTTP 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. I did some Googling, and found several similar problems, but nothing exactly like I have. The closest one seemed to indicate permissions. So I recreated the site and set it up to allow the Administrator (in Windows) to access the stuff. That didn't help. I can read/modify the files just fine from within Windows, but IIS itself can't seem to do it. What do I need to do to fix this? Thanks!

• MAMP Pro virtual hosts on Mountain Lion not being recognized

  - by user135242

  I'm running MAMP PRO 2.1.1 on OSX 10.8.1 and not having any luck getting Apache to recognize any hosts that have been set up in MAMP besides localhost. This only happens when trying to use port 80. When I switch to port 8888 everything runs fine. Mountain Lion's Apache has been disabled and I get no errors or warnings when starting MAMP and the servers. Any doc root I set for "localhost" runs without problem. Any other server name I define, however, results in "cannot connect" when viewing in Chrome (not to be confused with "cannot find" - the browser is in fact following /etc/hosts to 127.0.0.1, but MAMP's Apache is simply not responding) I was wondering if anyone else has run into this issue or knows how to solve it. I'm working on some WordPress development and it keeps wanting to redirect to the base URL (with no port reference) even during setup. I'm sure I could fix things from the WP side but I'd rather figure out what the root issue is with MAMP. Thanks in advance for any insight you can provide.

• ixgbe driver: Limit the max number of cores

  - by Shellex Wai

  I have a Linux workstation with 48 cores and runs ixgbe driver for fiber interface. And I have to test a project name Netmap on it. NetMap is a high performance network framework for high speed interfaces, which has been ported to Linux recently. For some reasons, I must try it on the machine. So I compile it and follow the instructions to run the test problems, but it doesn't work. I check dmesg and it says: [10399.085736] 794.159015 netmap_set_ringid [486] ringid o4o1 set to all 48 HW RINGS [10399.085742] 794.282011 netmap_obj_malloc [220] netmap_if request size 816 too large I asked the author of netmap for help. He told me that I have too many cores in the machine and it should work if I tell ixgbe use less cores (2 to 4 is ok). I am not familiar to driver development and I don't know how to limit the ring numbers by passing arguments to ixgbe driver. So I check the spec from intel's website but found nothing about it. So I come here for more helps. Thank you.

• rpmbuild gives seg fault

  - by Deepti Jain

  I am trying to build an rpm using the rpmbuild tool. I have source code which build binaries around 30 GB. This software for which I am making the rpm has dozens of executables. When I copy only the binaries of a single executable (Eg. init) my rpm builds successfully. But when I dump the entire build to the rpm, rpmbuild does everything but gives a seg fault in the end. Here is my spec file: # This is a sample spec file for wget %define _topdir /root/mywget %define name source %define release 1 %define version 1.12 %define _builddir /root/mywget/BUILD/glenlivet %define _buildrootdir /root/mywget/BUILDROOT %define _buildroot /root/mywget/BUILDROOT %define _sourcedir /root/mywget/SOURCES BuildRoot: %{_buildroot} Summary: GNU source License: GPL Name: %{name} Version: %{version} Release: %{release} Source: %{name}-%{version}.tar.gz Prefix: /usr Group: Development/Tools %description The GNU sample program downloads files from the Internet using the command-line. %prep %setup -q -n glenlivet %build cd %{_builddir} make all %install rm -rf %{_buildrootdir} mkdir -p %{_buildrootdir}/bin cp -p -r %{_builddir}/build/obj-x64/* %{_buildrootdir}/bin/ %files %defattr(-,root,root) /bin/* If I only copy some of the binaries (let say one utility and its dependent binaries) it works fine. But when I try to copy the entire build, I get a seg fault. I get the seg fault after rpmbuild has executed these sections: %prep %build %install rpmbuild also processes my source file.

• Fixing a typo in machine name

  - by justSteve

  When i installed windows i had a typo in the machine name that i corrected from the system's 'Computer Name/Domain Changes' - the workstation is a member of a workgroup not a domain. From everything i can see the renamed machine name is correct. Shift gears.... I'm importing SQL logins from my remote server to this, my development workstation and have used the script presented here - a script that generates a CREATE statement for each login found. While I was preparing to run this script's output (from the remote box) i needed to change the domain name from the remote to my local's name - so i ran the same script locally (in order to see what SQL things my domain name is. SQL has the original machine name - the one with the typo. However, the scripts are tossing errors if i try to create logins with that identifier. CREATE LOGIN [Setve\Admin] FROM WINDOWS WITH DEFAULT_DATABASE = [master] But works correctly if i use the updated machine name: CREATE LOGIN [Steve\Admin] FROM WINDOWS WITH DEFAULT_DATABASE = [master] So the problem is: do i have a problem i need to solve? Somewhere, deep in the guts of SQL Server, it has record of a Domain name that does not exist. Should i find and fix that discrepancy? thx

• Mac updated just now, postgres now broken

  - by user52224

  I run postgres 9.1 / ruby 1.9.2 / rails 3.1.0 on a maxbook air for local dev. It's all been running smoothly for months, (though this is the first time I've done development on a mac.) It's a macbook air from last year, and today I got the mac osx software update message as I have a few times before, and my system downloaded approx 450mb of updates and restarted. It now says it's on OSX 10.7.3. Point is, postgres has stopped working, when I start my thin server (mirror heroku cedar) as normal, and then browse to my rails app I get: PG::Error could not connect to server: Permission denied Is the server running locally and accepting connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"? What happened? After browsing around a few questions I'm still confused, but here's some extra info: Running psql from command line gives same error I can run pgadmin 3 and connect via it and run SQL no problems Running which psql shows the version as /usr/bin/psql I created a PostgreSQL user back when I got the mac (it's always been on lion) I've no idea why, almost certainly I was following a tutorial which I neglected to store in my notes. Point is I am aware there is a _postgres user as well. I know it's rubbish, but apart from a note on passwords, I don't have any extra info on how I configured postgres - though the obvious implication is that I did not use the _postgres user. Anyone have suggestions or information on what might have changed / what I can try to debug and fix? Thanks. Edit: Playing around based on this question and answer: http://stackoverflow.com/questions/7975414/check-status-of-postgresql-server-mac-os-x, see this string of commands: $ sudo su postgreSQL bash-3.2$ /Library/PostgreSQL/9.1/bin/pg_ctl start -D /Library/PostgreSQL/9.1/data pg_ctl: another server might be running; trying to start server anyway server starting bash-3.2$ 2012-04-08 19:03:39 GMT FATAL: lock file "postmaster.pid" already exists 2012-04-08 19:03:39 GMT HINT: Is another postmaster (PID 68) running in data directory "/Library/PostgreSQL/9.1/data"? bash-3.2$ exit

• Why is the `remove rows` button not always present in MySQL Workbench?

  - by Shawn

  I'm using MySQL Workbench to remove rows from a table in my database. Most of the time, I will simply write a select statement, then select the rows I want to erase and use the remove rows button (circled in the screenshot below). But sometimes (quite often actually), the remove rows button does not appear. Instead, I get something like the screenshot below: The remove rows button is not there and the remove rows option is grayed out in the context menu, so basically, I can't remove rows... The only way I've found of solving this issue is to run the select query many times until the button appears (it usually does after 3 of 4 times). Does anyone know why this is happening? UPDATE Today, I've been running a select query dozens of times and the button never appears. It seems my incomprehensible workaround no longer works... Help! btw: Using a delete statement does work, though I would rather not have to write one for each row I want to remove as this happens quite frequently during development...

• How can I remedy the always-on-top window problem?

  - by GateKiller

  Sorry for the vague title but this one is hard to explain so bear with me please. I'm using Windows Vista at work for web development and sometimes when I Click or Alt-Tab to background window, the window will get focus but it will not be brought to the front. In order to bring the window to the front, I have to click on the applications border (when the resize cursor appears) and the window will then jump to the front. I've had this problem for about a year now and it happens at least a dozen times a day, but it doesn't do this all the time - seems random. I hope I have explained the issue fully (and you've understood it) and would appreciate any constructive answers or comments to solve this problem. Example: If I Alt-Tab from Google Chrome to Notepad and this problem randomly occurs, Google Chrome will remain in front of Notepad, however, I will be able to type text into Notepad while the window is behind Google Chrome. Clicking on Notepad's content area will not bring it to the front but clicking it's window border will. Video Exampe http://vimeo.com/19388998 In this video, I clicked from Google Chome to UltraEdit and chrome stayed in font, but as you can see, I can still type in UltraEdit. I'm starting to believe that this could be a bug in Google Chrome so I'll continue to watch if this between other applications.

• How to setup a virtual machine in Ubuntu desktop to run Debian Server

  - by stickman

  I want to run a virtual machine in my Ubuntu desktop that runs a Debian server. The purpose of this is to generate Debian packages. I have some C++ applications that were originally developed on my Ubuntu machine, and I need to (re)compile them on a Debian server in order to: build Deb packages for deployment on a Debian server make sure that the applications will definitely work on a debian server The idea is so that I can do 90% of my development on Ubuntu (where I am more comfortable), and deploy a binary package that definitely works on Debian. BTW, I am developing on Karmic Kola (Ubuntu 9.10). [Edit] Following the advice I got so far, I have installed debootstrap and Debian 'Lenny' on /srv/chroot/debian_lenny on my machine. I am not sure this is the server version, but in any case I dont think that matters for my purposes (though it would be useful to know how to specifically install the server version). At the moment though, I am like a fish out of water, since there is no GUI, and it is only a console that I have in the chroot jail. I had a look in the home folder (I cheated, by using the KNavigator in Ubuntu), and there are no folders there - which presumably mean that no users have been set up as yet in the Debian "system". I would like to know how to do the following: Download and install the dev tools needed for (re)compiling my C++ apps Copy my projects from the Ubuntu "system" to the Debian "system" After building the binaries, I would like to create a debian binary package containing all of my binaries, so that I can install the package on a Debian server (my remote server)

• Nginx flv audio pseudo stream works but video is not loading

  - by sarah

  I am working on a development server for a company & they want nginx webserver to work with. So the requirements for their company is, it should be capable of doing following things i.e hotlink protection, mp4 & flv pseudo stream & secure streaming. However nginx fulfills their requirements and i am configuring their server from past 2 days as i am new to this field so i've only acheived hotlinking prevention in past 2 days. But the problem on which i am stuck is flv pseudo streaming, to make work to mp4 pseudo stream it was just a piece of paper but i am really fuc*ed up with flv pseudo stream. I have converted my flv videos with flvmdi tools to insert many keyframes but the problem is , when i try to seek video from following keyframes that are generated by flvmdi i.e test.flv?start=2681223, video does not load but audio pseudo works fine. So it means no problem with my flv configuration in nginx.conf file. And the forum that i used to compile my nginx-1.2.1 is http://h264.code-shop.com/trac/wiki/Mod-H264-Streaming-Nginx-Version2 & by adding additional module --with-http_flv_module. This forum is really active, hopes i will resolve my problem as soon as you guys will provide me some guide.

• Connections to SSH and Samba suffer from heavy delay

  - by Till Helge Helwig

  There are a lot of questions about SSH connections being delayed, which usually can be fixed by disabling the DNS lookups. Unfortunately this doesn't seem to be my problem. Our development server is accessed via SSH and Samba. When opening a connection to the server (either SSH or Samba) it takes a very long time. Accessing a Samba share via Windows is basically impossible because there is a timeout. Using smbclient works, but takes ages. When opening a SSH connection I get immediately prompted for the password and after hitting Enter the terminal instantly shows the MOTD. Afterwards it takes about a minute for the prompt to appear. I watched the load of the server while connecting via SSH and Samba and could not find anything out of order. There is nothing out of the ordinary running and hogging up memory and CPU or something. I have no clue where this delay might come from. I already tried UseDNS no in sshd_config and proxy_dns = no in smb.conf, but to no avail. Any idea about what might cause this would be greatly appreciated!

• SSH does not allow the use of a key with group readable permissions

  - by scjr

  I have a development git server that deploys to a live server when the live branch is pushed to. Every user has their own login and therefore the post-receive hook which does the live deployment is run under their own user. Because I don't want to have to maintain the users public keys as authorized keys on the remote live server I have made up a set of keys that 'belong's to the git system to add to remote live servers (In the post-receive hook I am using $GIT_SSH to set the private key with the -i option). My problem is that because of all the users might want to deploy to live, the git system's private key has to be at least group readable and SSH really doesn't like this. Here's a sample of the error: XXXX@XXXX /srv/git/identity % ssh -i id_rsa XXXXX@XXXXX @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: UNPROTECTED PRIVATE KEY FILE! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Permissions 0640 for 'id_rsa' are too open. It is required that your private key files are NOT accessible by others. This private key will be ignored. bad permissions: ignore key: id_rsa I've looked around expecting to find something in the way of forcing ssh to just go through with the connection but I've found nothing but people blindly saying that you just shouldn't allow access to anything but a single user.

• Liked Arch Linux - but I am still not sure if its the right distro for me...

  - by BlackAndGold

  As the title says... I used Arch Linux for a while and liked it a lot: leightweight, sleek, fast and well documented with a great community. However I had to format my hd and for the sake of being too lazy to reinstall arch, I used windows 7 exclusively for a while. Now I want to get back to linux again (still dual boot), mainly for web development purposes and using handy tools such as rsync ect. Again, I liked Arch, but there is too much tweeking, too much reading up and too much figuring out what to do as well es some bad suprises especially when you need them the least and when just quickly want to get some work done. I kind of would like to have a little more "out of the box" distro that is still fast and somewhat leighweight and of course reliable. I actually considered Ubuntu, which I am not too big of a fan of, but I will still give the minimal install a shot. However other distros seem interesting as well, such as crunchbang and mint debian ecpecially. My question, hoping this isn't too boring for many you, what is the right distro for me?

• 403 Forbidden serving static files from VirtualBox shared folder with nginx (Ubuntu 10.04LTS guest, Windows 7 host)

  - by Chris Pratt

  I'm working on a local development VM and trying to test serving my site with gunicorn and nginx as a reverse proxy for static resources only. The site loads minus static resources with user nginx; in nginx.conf. Attempting to load a static resource individually reveals a 403 Forbidden error. For background. The static resources are in a shared folder under /media/sf_work. All files are owned by root:vboxsf (VirtualBox default). My user account on the system has been added to the vboxsf group, and I have full access to the shared folder. For comparison, I tried changing the nginx.conf user to my user account. In that scenario, the static files did load, but then the homepage itself gives a 403 Forbidden error. So, I then tried adding the nginx user to the vboxsf group, but then everything gives a 403 Forbidden error. After further investigation it seems that if the nginx.conf user is in any group, it results in a 403 Forbidden. Any idea what could possibly be going on here?

• Run a rails server on Amazon EC2 [on hold]

  - by Jashwant

  Context: I've tried rubber gem, but that does not fulfill my requirements ( I needed to deploy on existing instance, so don't recommend me rubber) So, I followed this excellent tutorial http://stackoverflow.com/questions/15535140/installing-ruby-2-0-and-rails-4-0-0beta-on-aws-ec2 Now, I have ruby 2.0 and rails 4.0.0 running on AWS EC2. I successfully ran the server with RDS (mysql) as db and default webrick as server ( Using command rails server ) But, I've read that webrick is a development server and shouldn't be used at production. What I tried: I googled and came up with some alternatives. Capistrano Nginx / apache with passenger Passenger with Capistrano Unicorn Puma My Question: What exactly is capistrano / passenger ? Are they middleware to ease my deployment process ? I don't see any difficulty in doing rails server command. If they are just middleware, nginx with passenger and capistrano does not make any sense ? Why would I add a learning curve ( to learn nginx, passenger and capistrano configs) just to run my server ? I can just use nginx to deploy my app. Can't I ? What combination should I use on Amazon EC2 (or may be at any some other production server).

• Recommended programming language for linux server management and web ui integration.

  - by Brendan Martens

  I am interested in making an in house web ui to ease some of the management tasks I face with administrating many servers; think Canonical's Landscape. This means doing things like, applying package updates simultaneously across servers, perhaps installing a custom .deb (I use ubuntu/debian.) Reviewing server logs, executing custom scripts, viewing status information for all my servers. I hope to be able to reuse existing command line tools instead of rewriting the exact same operations in a different language myself. I really want to develop something that allows me to continue managing on the ssh level but offers the power of a web interface for easily applying the same infrastructure wide changes. They should not be mutually exclusive. What are some recommended programming languages to use for doing this kind of development and tying it into a web ui? Why do you recommend the language(s) you do? I am not an experienced programmer, but view this as an opportunity to scratch some of my own itches as well as become a better programmer. I do not care specifically if one language is harder than another, but am more interested in picking the best tools for the job from the beginning. Feel free to recommend any existing projects except Landscape (not free,) Ebox (not entirely free, and more than I am looking for,) and webmin (I don't like it, feels clunky and does not integrate well with the "debian way" of maintaining a server, imo.) Thanks for any ideas!

• How can I install git on RHEL 6?

  - by JR.Xyza

  I'm trying to install Git on a RHEL6 development server, I have experience with Ubuntu but this is my first time working with RHEL (I'm a developer trying to fill in for a recently departed Linux Sysadmin). I've set up two additional repos (EPEL and IUS) for other packages needed for a Magento install. Output of yum repolist: [root@box]# yum repolist Loaded plugins: product-id, security, subscription-manager Updating certificate-based repositories. repo id repo name status epel Extra Packages for Enterprise Linux 6 - x86_64 7,841 ius IUS for RHEL 6Server - x86_64 135 Most of what I've read indicates a simple 'yum install git' should work with EPEL enabled, but I get the dreaded [root@box]# yum install git Loaded plugins: product-id, security, subscription-manager Updating certificate-based repositories. Setting up Install Process No package git available. Error: Nothing to do Same goes for git-daemon, etc. I've tracked down a number of git RPMs such as this one at repoforge but they require a train of dependencies that seems to never end. I've also toyed with compiling it manually but the rabbit hole to get make working seems to go even deeper. I'm convinced there's a simple oversight somewhere keeping me from being able to install from the EPEL repo, but I'm a rookie at all this. Thanks in advance for help/pointers/additional resources.

• TortoiseSVN client slows Explorer to a crawl in Windows XP running in Parallels

  - by Cory Larson

  I thought I'd make my first SuperUser question relatively simple, though it's the kind of question that may not get many responses as I'm not directly involved with the issue. A colleague does his development in Windows XP running in Parallels on his Mac. We've just migrated our VSS repository to SVN, and we've gone with TortoiseSVN as our client of choice with the Ankhsvn plugin for Visual Studio. On his XP instance, after installing TortoiseSVN, browsing through folders using Explorer is extremely slow; about 15 - 30 seconds before the contents of the next folder displays. It's the slowest when opening My Computer. Once he reaches a folder that contains the working content of an SVN project, Explorer behaves quickly again as expected. It seems that TortoiseSVN may be spending a bunch of time searching subfolders for stuff so it can do its icon-overlay thing, but that's just a guess. I've used TortoiseSVN for years on both XP and Vista on far less powerful machines without any issues with Explorer, so I'm attributing the slowness to it being run in a VM, though that may not be the actual issue. So has anyone encountered similar performance issues, and/or know of a fix? Keep in mind that any requests to make changes to his configuration will need to be communicated and thus my response time might be slow. Thanks everyone!

• Multiple Rails apps on same subdomain?

  - by Derek

  I recently decided to try out Rails. When working with PHP, I simply had all of my PHP projects in the same directory. For example, I may have http://ubuntu/app1, http://ubuntu/app2, etc. I created a subdomain for Rails (http://ruby.ubuntu), installed Rails and Passenger and everything is working. However, I may be wrong, but it looks like I can only have one Rails app per subdomain? My VirtualHost is as follows: <VirtualHost *:80> ServerName ruby.ubuntu ServerAdmin webmaster@localhost DocumentRoot /var/www/ruby/blog/public <Directory /var/www/ruby/blog/public> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all RailsEnv development </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> All of my PHP and misc. files are stored in /var/www/main. I want to be able to store all of my Rails apps in /var/www/ruby. I tried changing DocumentRoot to /var/www/ruby, but I don't think it's as simple as that. When I browse to a Rails app's Welcome Aboard page and click on "About my application's environment," I get a 404 page, but when the DocumentRoot is set to the public directory, I get the expected result. I don't want to have to create a new subdomain every time I create a new project. Is there any way I can make it so I can store all of my apps in /var/www/ruby, and browsing to http://ruby.ubuntu will let me access all of my Rails apps there? That way if I want to create a new app, all I have to do is rails new app, no Apache .htaccess or VirtualHost configuration required.

• Mac OS X will only upload zero-byte files through FTP

  - by tabacitu

  I'm using Mac OS X Lion and i've been having this problem with FTP (any FTP client, mind you. I tried Transmit, FileZilla, Cyberduck and the Terminal, all with the same result) I can browse files in my FTP Client, but when I upload files, the client hangs for a few seconds, then thinks it uploaded the files successfully, but it only creates a new file with one blank line in it. Sometimes, it manages to upload 4-5 lines. It then returns: 226 - Error during read from data connection 226 Transfer aborted But 2xx is a success message. It is not a server issue, since any Windows machine will upload just fine using the same network. Can anybody figure out what the problem is? It renders my mac useless for web development. The problem persists with SFTP and FTP with SSL/TLS. Later edit: Solved! Ok, turns out the problem goes away when I take out my router and connect directly through PPPoE. So the problem is with the router, I thought. But no, the problem is with the mac that connects through a router that connects through a PPPoE and tries to upload using FTP. Pretty specific, I know. The problem is with the MTU (maximum transmission unit). Apparently, mac os x breaks the file into chunks that are too large for the router to send, because the router's MTU was set lower than Mac OS X's. My router's was 1492, which is ok, but my Mac's MTU was 1500, which is unacceptable. I don't even understand why it works directly with PPPoE. Anyway, if you encounter the same problem, this is how you diagnose and fix it: In terminal, run: ifconfig | grep mtu to see what the MTU is for en0 (or en1, mine was en0) If it's 1500, run sudo ifconfig en0 mtu 1300 This should solve it. If so, it may only be until the next restart. You can also change the MTU in System Preferences \ Network \ Ethernet - Advanced \ Hardware

• How do I change file protections running XP on a disk from Windows Server?

  - by cdkMoose

  I had a Windows Server 2003 machine running at home, along with my desktop which I use for development. Server went belly up, but since my desktop is reasonably powerful, I figured I would move the disk from the file server (it was OK) into my XP machine to keep all of the files. Disk comes up fine and shows all of the files. I have been getting access denied errors when trying to work with some of the files. When I display attributes in Explorer, none of them are marked Read-Only. When I view properties on the directories, the Read-Only checkbox is not checked, but has a green background(which I thought meant mixed usage for files in the directory). When I click on the checkbox to clear it and click Apply, the disk does some work and all looks well. However, I continue to get the Access Denied errors, the files still don't show any Read-Only attribute and the directory properties shows the green background again on the Read-Only checkbox. I did check the box which says to apply the change to the folder and all files /subfilders under it. I am assuming that the issue relates to userids/permissions carried over from the Server install. So, why does it let me think I can change the attribute when I can't and how can I correct this problem so that the disk correctly recognizes the ids from XP?

  I've got a development Ubuntu system for which I have several users: myself (with full sudo) and about 5 other users. (I've set up the system so everything in this respect is still at its default setting) I'm trying to set the system up so that multiple people can collaborate in a single directory by using grouing and I want the default permissions to be 664. However when some users edit files the permissions were 644. After a lot of investigating most users have a umask (checked at the prompt) of 0002 and when they create files they are 664 (as expected) but there are 2 (myself and one other) who have 0022 umask (so the files that come out are 644 and nobody else can write to them). I've looked everywhere but can't figure out why a couple users wind up with a different umask e.g. there is nothing the .bash_profile or anything like that) Any ideas for the source of the discrepancy? /etc/bashrc if [ $UID -gt 199 ] && [ "`id -gn`" = "`id -un`" ]; then umask 002 else umask 022 fi /etc/profile if [ $UID -gt 199 ] && [ "`id -gn`" = "`id -un`" ]; then umask 002 else umask 022 fi EDIT: My (bad) ~/.bashrc # .bashrc # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi # User specific aliases and functions export LANG=en_US.utf8 Other user (good) .bashrc # .bashrc # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi # User specific aliases and functions

• Server not resolving after restart

  - by DomainSoil

  I restarted our server today, and now cannot for the life of me get anything to resolve... I suspect it has something to do with our routes. I've tried numerous Google results to no avail. Here is as far as I've gotten: [root@www ~]# route -n Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.101 0.0.0.0 255.255.255.255 UH 0 0 0 eth1 0.0.0.0 192.168.1.101 0.0.0.0 UG 0 0 0 eth1 Things you need to know: Our server (CentOS 6.3) runs two virtual machines, one live, and one development. They mirror each other as much as possible, but I can't find where I've went wrong with the live server. The dev server works fine. [root@www ~]# ifconfig eth1 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx inet6 addr: xxxx:xxx:xxxx:xxxx:xxxx/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:118206 errors:0 dropped:0 overruns:0 frame:0 TX packets:165 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7825749 (7.4 Mib) TX bytes:7146 (69.2 KiB) Interrupt:28 [root@www ~]# /etc/init.d/network status Configured devices: lo Auto eth0 Currently active devices: lo eth1 If there is any other information you need, please don't hesitate to ask!

• What Windows app can sort a huge XML file?

  - by Torben Gundtofte-Bruun

  I have some enormous XML-based configuration files, with 125000 lines in them. The problem is that they are auto-generated by the system I use, and "child" tags are in a random order within their respective parent tag. This means that a diff comparison is impossible. I want to recursively sort all tags within a parent tag by the value in name="". Some parent tags only appear once and don't have a name="" parameter; these should be sorted by the tag name itself. Once the files are sorted like this, they can be compared quite easily using normal tools. We are currently using ExamXML which can match unsorted XML files, but it fails because the files are too big. Is there an application that can do this? (Windows much preferred; Linux only as a last resort) I do not want to dive into development or XSLT jobs. I am thinking that someone must have made a simple sorting tool like this already - I just can't find it using Google. Update: With help from this site, I created a small package that I want to share: XML-Sorter_v0.3.zip Update: Follow-up question here.
