• Error starting nginx and passenger 3 for Rails app on Suse Linux

  - by thesis

  I have configured passenger on SuSe Linux using simple configuration procedure (calling passenger command and then installing all libraries wich are needed), but now it throws an error.. Is there any solutions how to fix it? test@linux-p1g4:~/test_app/myapp> passenger start *** ERROR *** Could not start Passenger Nginx core: [alert]: could not open error log file: open() "/tmp/passenger-standalone.22737/logs/error.log" failed (2: No such file or directory) [alert]: Unable to start the Phusion Passenger watchdog because its executable (/var/lib/passenger-standalone/3.0.2-x86_64-ruby1.8.7-linux-gcc4.5.0-1002/suppor t/agents/PassengerWatchdog) does not exist. This probably means that your Phusion Passenger installation is broken or incomplete, or that your 'passenger_root' directive is set to the wrong value. Please reinstall Phusion Passenger or fix your 'passenger_root' directive, whichever is applicable. (-1: Unknown error 18446744073709551615) Stopping web server... done

• Puppetmaster don't notice changes to site.pp

  - by tore-

  Hi, I've just setup a new production environment with puppet. Using 0.25.4 in client/server. Ruby is at 1.8.5, CentOS 5.4. I've made a simple manifest for configuring yum-updatesd, but the puppetmaster doesn't seem to notice changes done to site.pp: err: Could not parse for environment production: Could not match 'node' at /etc/puppet/manifests/site.pp:1 err: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not parse for environment production: Could not match 'node' at /etc/puppet/manifests/site.pp:1 Notice, it says line 1. But line 1 contains an import statement: # cat -n /etc/puppet/manifests/site.pp 1 import "update-notification" 2 3 node default { 4 include update-notification 5 update-notification::configure() 6 } I've tried to reboot the server, delete and recreate site.pp, start and stop puppetmaster and puppet, with no luck. What am I missing?

• OSX Lion - sh: mysql command not found

  - by mkk

  I have pretty simple issue I believe. I have successfully installed mysql etc. I do not have any problems with running "mysql" command from terminal [ bash ]. Suddenly, when my application tried to run mysql command I got error: sh: mysql: command not found.. In terminal, when I type sh and then mysql I can log in to mysql without any problems. I have added mysql to PATH in .bash_profile and I suspect this is why sh cannot see it. I have cp .bash_profile to .profile but it did not do the trick, any ideas how can I fix this issue?

• Creating a development environment from a shared hosting production environment (LAMP)

  - by bobo

  The production server is shared, I don't have access to php.ini and httpd.conf and most PHP settings cannot be set or overrided using ini_set PHP function. So I would like to create a local development environment having configurations as close as it can be to those of the production environment (LAMP). I don't have shell access to the server but using exec PHP function to run some simple commands is possible. I am using Windows XP Pro and I am going to install on VMWare a linux distribution that is more or less the same as the production server. However, installing apache, mysql and php, and then configuring them like those on the production server is not a easy task. It would be great if there exists any tools that are useful in this situation, tools that can analyze/ inspect the production server and then produce something that can help replicating the environment would be useful. If not, what should I be aware of when I try to manually replicate the production environment?

• Multi users windows login?

  - by DennyHalim.com

  I need a way to login multiple users into windows at startup, in (XP/Vista/7) I need for each time windows starts, all registered users will automatically login and starts all apps in their startup folder under their own credentials. Any ideas how I could achieve this? i need a 'cheap' alternative to windows vps. lots of people need vps to run certain apps and leave it running. it's less likely they need full admin access other than installing those apps. instead of each users have their own vps running simple apps, it might be cheaper to have one multi-user server to accomplish this?

• Which Linux is the most efficient?

  - by quandary

  Simple question: There is a gazillion Linux distributions out there. Which one (distribution/incl. window manager) makes (technically) the most efficient use of my (aging) computer ? I have appx. 1 GB RAM and a 1.6 GHz processor, 120 GB hd. I develop applications (C++/.NET/mono/ASP/PostGre SQL/). Usually, I prefer distros with apt-get. Anybody knows which one takes the most care of my limited RAM, and wich one is the fastest/slimmest of them all, that has a decent repo and is damn fast)

• Mounting NFS share between OSX and Centos VM

  - by Adam

  I'm having issues mounting an NFS share I've made on my Mac host (server) from a Centos VM (client). I'm getting a permission denied error. I have this line in /etc/exports on server: /Users/adam/Sites/ 192.168.1.223(rw) and in /etc/fstab on client: 192.168.1.186:/Users/adam/Sites/ /home/adam/Sites/ nfs rw 0 0 I'm sure this is a simple configuration issue, but I've never set up NFS properly before.

• Reverse proxy with SSL and IP passthrough?

  - by Paul

  Turns out that the IP of a much-needed new website is blocked from inside our organization's network for reasons that will take weeks to fix. In the meantime, could we set up a reverse proxy on an Internet-based server which will forward SSL traffic and perhaps client IPs to the external site? Load will be light. No need to terminate SSL on the proxy. We may be able to poison DNS so original URL can work. How do I learn if I need URL rewriting? Squid/apache/nginx/something else? Setup would be fastest on Win 2000, but other OSes are OK if that would help. Simple and quick are good since it's a temporary solution. Thanks for your thoughts!

• One IP, One Port, Multiple Servers

  - by Adrian Godong

  I am looking for a solution to forward one public IP address and one specific port to different machines based on hostname (as of now, I need it only for HTTP). The current setup is NAT on a commodity router (it only provide simple public port to private IP address / port forwarding). I can add a Windows Server 2008 R2 machine before the router if required, but prefer not to do so. So ideally, I would like to have the current setup and the forwarding is done on one of the Windows Servers. Is it possible to do this?

• Huawei E170 on Linux?

  - by torbengb

  Related to this question, I need to know if the specific combination of Ubuntu 9.10 + the Huawei E170 (HSDPA broadband modem USB stick) will work? Bonus points for a link to a webpage that decsribes exactly how it is done! Specifically, I'm in Austria and the telco is A1, but I hope that the setup would be the same regardless of location/provider. I have found these two pages that seem horribly complicated to a Linux noob. Is there a simpler way, or do I really need to dive into that? Your input is much appreciated! If I can get confirmation that it's supported, then I'd switch to Ubuntu Netbook Remix, because I'm already running Ubuntu on the main pc at home and I'd like to keep things simple.

• Asterisk - Trying to use call files to create a conference call between two dynamic numbers

  - by Hank

  I'm trying to setup an Asterisk system that will allow me to create a conference call between two dynamic numbers. It seems I can use 'call files' to make Asterisk initiate the call without needing an incoming call - http://www.voip-info.org/tiki-index.php?page=Asterisk+auto-dial+out This example seems to be what I'd need: Channel: SIP/mytrunk/12345678 MaxRetries: 2 RetryTime: 60 WaitTime: 30 Context: callme Extension: 800 Priority: 2 I can generate this file with some scripting language and then place it into the Asterisk Call File folder. The problem I'm having is: How do I call out to two numbers and join them in a conference call? The MeetMe plugin/extension seems to be what I need in terms of conference calling, I'm just unsure as to how I'd use the two together and join them. Also, is it possible to have multiple 2-person conference calls at the same time? Is setting this up as simple as setting aside X amount of 'channels' in the meetme.conf?

• Variable parsing with Bash and wget

  - by Bill Westrup

  I'm attempting to use wget in a simple bash script to grab a jpeg image from an Axis camera. This script outputs a file named JPEGOUT, instead of the desired output, which should be a timestamp jpeg (ex: 201209292040.jpg) . Changing the variable in the wget statement from JPEGOUT to $JPEGOUT makes wget fail with "wget: missing URL" error. The weird thing is wget parses the $IP vairable correctly. No luck on the output file name. I've tried single quotes, double quotes, parenthesis: all to no luck. Here's the script !/bin/bash IP=$1 JPEGOUT= date +%Y%m%d%H%M.jpg wget -O JPEGOUT http://$IP/axis-cgi/jpg/image.cgi?resolution=640x480&compression=25 Any ideas on how to get the output file name to parse correctly?

• Setting a custom timeout to nmblookup

  - by C2H5OH

  As part of a batch script, I have the following command: hostname=$(nmblookup -A $ip_address | awk '$2 == "<20>" {print $1}') Which works fine from a functinality perspective, even for unresolved hosts. The problem is that when the IP address is not reachable or the remote machine does not respond to the SMB request, the command takes about ten seconds to complete. Therefore, the question is simple: is there a way to lower the elapsed time in such cases? Or, in other words, is there a way to set a custom timeout for the nmblookup command? NOTE: I'm interested in solutions that do not make use of SIGALRM or similar mechanisms; if they exist. The nmblookup version is 3.6.3 from Ubuntu 12.04 LTS.

• General purpose ticketing/tech support system [closed]

  - by crazybyte

  Possible Duplicate: What’s your favorite ticketing system? I was wondering if somebody could recommend me a very user friendly or simple general purpose ticketing/tech support system. I need something that is web based, preferably open-sourced/free software implemented using PHP, Ruby, Ruby on Rails or Java (as back end) with MySQL or PostgreSQL as database engine. I need something that is not development management oriented or project management oriented like Eventum or similar (random example), something to which the user can connect open a tech support request and be able to follow it until is solved or dropped.I need it to be open-sourced to be able to modify it if there is a need or extend it. I tried a number of such systems available and I found that osTicket or eTicket is something that it's close to what I need, but the code is somewhat flaky and some of the features are working badly or behaving strangely. Any thoughts/advice where to find something similar? Thanks!

• Java file manager won't load in Firefox

  - by Arthur

  I am using Webmin and I can't get the file manager to load in Firefox. It is a simple, Java based file manager. When I try to load it I get the following error: This module requires java to function, but your browser does not support java Internet Explorer works fine and I have yet to try on Chrome. Java is installed and I have the same problem on Windows and Linux. Java seems to work fine with everything else, with the exception of webcams. Any advice on the issue would be appreciated. Edit: I just checked and it doesn't work in Chrome either.

• Ubuntu mount hard drive confusing

  - by Fresheyeball

  I'm new to linux and have a home server set up running ubuntu. In the ui its very easy to mount my additional internal harddrives. I just double click on them. Since I have made this server headless, I now need to mount via the command line. How can I replicate the very simple double click gui behavior? So far all the information I've found is very complex. Ubuntu auto generated folders for each hd in under /media and I can see the harddrives under /dev but have no idea which is which as the hardware is identical between them. I also don't know how they are formated. Thanks in advance for any advice you have.

• Copying files from NAS to NAS drives

  - by user1001421

  Very simple question. I've got 2 NAS drive that are "wire" connected via a router. If I have a wireless laptop and request a large amount of data be copied from one NAS drive to the other, does the network traffic go direct from the one drive to the other, going via the wired network, or does the network traffic go via my laptop, if you see what I mean. IE. From the NAS drives wired network, to the wireless network and then back to the wired network. Is this a common bottle-neck when copying a large amount of data? And if so, is there a way to avoid it. Thanks.

• SQL Server 2005 to 2008 upgrade - are MDF files binary compatible?

  - by james

  I have 50 databases on a MS SQL Server 2005 system and want to upgrade to MS SQL Server 2008. This is what I tried on some test machines: 1. copied the \DATA directory from the source (MSSQL 2005) to exactly the same path on the target (MSSQL 2008) server. 2. edited the startup parameters on the MSSQL 2008 service to point to the path of the MSSQL 2005 master database. 3. restarted MSSQL service It worked and I can access all databases, tables and data. My questions are: I go back to SQL Server 4.2 and it has never been this easy. I know it worked, but should have it worked? Am I missing something, or is there going to be a gotcha next week? These are simple databases, with just tables, views and indexes. No cross database links, no triggers etc

• Installing an EC2 (EBS based) instance on another AWS account

  - by imaginative

  We're moving from one AWS account to another. I have a couple of EC2 instances I would like to move over. These instances are EBS based. Googling around, I'm seeing all sorts of convoluted answers for how to appropriately launch this EBS based instance on a new account. Surely there has to be a simple way of going about this. As of right now, what I have done so far is backup the EB2 Volume as a snapshot. I then altered the permissions of the snapshot to allow the new AWS account number to be able to access it. I am not sure where to go from here. Do I have to create an image from the EBS snapshot? Upload it to S3? What's the next step(s)?

• Software for failover across multiple external hosts

  - by Lin

  I have multiple webservers with the same content, hosted across different providers. However, I can't seem to find a nice, simple failover solution. Load-balancing software (Pound, HAProxy, etc.) are unnecessary, and I need the flexibility to manage over 100+ domains, so the paid DNS failover solutions I've found are too expensive. So far the simplest solution I've thought of is just to set a very low TTL (30min - 1hr) in each zone entry on my nameservers (running BIND). Then, continuously monitor each server, and temporarily remove failed servers from zone entries. But this seems like something that should be currently available. I only have root access to different VPSes running CentOS. Any suggestions? Thanks!

• Make PATH variable changes permanent on openSuse

  - by Marlon

  Okay, so I'm trying to do something that should be rather simple but for some reason I can't quite seem to make it work. All I simply want to do is add a path to the PATH environment variable in openSuse. So far, I've edited the following line in /etc/default/su : PATH=/usr/local/bin:/bin:/usr/bin with this line : PATH=/usr/local/bin:/bin:/usr/bin:/usr/local/php/bin:/usr/local/mysql/bin Basically, all I want to do is have access to php and mysqld regardless of how I log in directly from the command prompt without having to type trailing /usr/local/php/bin/ every time. Am I even editing the right file? I'm a bit of a Linux newbie and to achieve something as trivial as this is eluding me. Server gods out there, drop be a crumb, please? :-)

• Disable ability to add startup items in Windows 7?

  - by Gam Erix

  Note: This is not the question "How to disable startup items" because the simple answer is: "Use msconfig". Now as for my question: I recently am very annoyed that some programs add startup items to my PC without my knowledge after installation, I always have 2 programs which startup - Temperature monitor and the Catalyst Control Center Tray. Now, sometimes I install something and it adds startup entries, how can I make sure that no startup entries can be added to windows anymore? So what I would like to do: -Disable adding scheduled tasks (even for administrator accounts, so programs installing from them can't add startup entries too) -Disable adding startup entries to the registry (even for administrators, would changing the permissions in HKLM on the Microsoft\Windows\CurrentVersion\Run to read only be enough?) -Disable all other methods of startup in Windows 7 I don't know -Set default startup of NEW installed services to "Start Manually" instead of/and block "Start Automaticly" and "Start Automaticly (Delayed)" How can I accomplish this? This is also a nice way to prevent most viruses fom running after machine reboot (if this can be accomplished).

• sqlcmd won't execute - Claims Native Client not installed properly

  - by nuit9

  I'm trying to use sqlcmd to execute some SQL scripts. Using a test command with a simple query like: sqlcmd -S HOSTNAME -d MYDATABASE -Q 'SELECT Names FROM Customers' sqlcmd does not appear to make any attempt to connect to the server as it displays this message: Sqlcmd: Error: Connection failure. SQL Native Client is not installed correctly. To correct this, run SQL Server Setup. The native client was presumably installed as part of the SQL Server setup and likely correctly. I actually get this message on any machine with SQL server installed trying to use sqlcmd so it's not a matter of the installation being corrupt. Unfortunately the message really tells me nothing about the problem so I don't know what the real issue is. I know the SQL Native client is working properly since a vbscript was able to execute SQL queries against the database. Is there some additional configuration needed to use sqlcmd?
