  • What are some SMART Criteria I can use when comparing "green" datacenters?

    - by makerofthings7
    I'm looking to reduce my carbon footprint and want to find a "green" datacenter.

What key words or technologies might those energy efficient datacenters be using?

  • Test Environment configuration Management

    - by TechTestDude
    I am after a solution which will enable me to enter all my hardware/software elements (sort of like resource management), create a set of 'test environments' and assign hardware and software to that test environment for a given period. The idea is so that everyone can see and update what they need in any given environment to meet their project needs. Does anyone know of any systems out there which can achieve this? Vendor recommendations are welcome, but please call out your interest in it.

  • Cheat Sheets for System Administrators?

    - by splattne
    I'd like to start a collection of good, free cheat sheet resources for system administrators. Please add your favorite ones. From the Wikipedia "cheat sheet" article: In more general usage, a "cheat sheet" is any short (one or two page) reference to terms, commands, or symbols where the user is expected to understand the use of such terms etc but not necessarily to have memorized all of them.

  • Microsoft Security Essentials Vs. Avast Home [Free] Edition on a netbook [closed]

    - by Sarath
    I am using Avast Home Edition in my Dell Mini 10v. As you know the notebook is using an under powered processor which is not really suitable for browsing some rich internet websites. So I am in the middle of improving the performance. Will uninstalling Avast and using Microsoft Security Essentials will improve the performance? the memory usage of avast is quite low but I can't compromise security. Is Security essentials a good bet?

  • Second WAN/LAN in office, want to share printers between them

    - by ndavis
    My business is growing so I've decided to purchase a second DSL line, to separate two departments to allow for more bandwidth usage. Previously I had a network printer that served both departments. With the addition of the second DSL line, I'm potentially going to have two separate LANs. How can I set it up so that the new LAN still has access to the Network Printer, but ensure that they are still using the new DSL line?

  • du excluding hard links possible?

    - by balor123
    I'm trying to determine how big a cloned Git repository is from a local file system. It creates hard links for some but not all files. How can I determine the disk usage of it? The best I can come up with is "du -a" right now with the original and again with the clone to determine the difference, since each hard linked file will be counted only once. Ideally, I would just run du on the clone and count each hard linked file zero times.

  • How do you use 4GB of RAM?

    - by Xeoncross
    I have a Quad Core Intel PC with 4GB of RAM - I've been using it over a year to run web server stress tests (ab.exe -n 5000 -c 500), encode HD video, play games, open hundreds of tabs in multiple browsers (simultaneously), worked on multi-layered +8000px art in photoshop and just about every other thing you can think of. As of yet I've never passed 2.3GB of RAM usage. How in the world do you use all 4GB? Is there any use for it?

  • Temporary DNS server

    - by arcyqwerty
    What DNS software is good for temporary usage while doing server maintenance? Since there is not a secondary server available, I would like a solution that can just run on a desktop/laptop just to keep the records updated (preferably without installation -- just reads the existing zone files) There are backup servers that rely on the master for zone transfers and it would be best not to reconfigure any of the domain record TTLs or the like Master DNS server is running BIND

  • Is there a way to check if a user has specific rights?

    - by Vadim
    In my application I'm using ntrights.exe, that is part of Windows Resource Kit, to grant and revoke a specific user right. For example to grant a user "Log on as a server" right, I execute using shell object following command: ntrights -u User +r SeServiceLogonRight However ntrights doesn't allow you to check if a user has a specific right. Can you tell me how I can check if a user has a specific right?

  • Major computer speed problems

    - by Glen654
    I've been running Windows 7 on my laptop for about a year now, and have had no issues regarding speed. About a month ago, my computer had what I refer to now as an "episode" where it runs extremely slow, when I open Task Manager I see no significant processes running, nothing out of the ordinary, but my computer is at 100% CPU usage. Usually restarting fixed this problem, but it seems to have gotten worse to the point where restarting does not fix this problem, and it's interfering with my work. What should I do?

    - by BassKozz
    Ubuntu Server 9.10 So there is the time command which will show you the time it took for a specific process/command to run after the command has completed. For example: :~$ time ls real 0m0.020s user 0m0.000s sys 0m0.000s I'd like to also collect the average CPU usage, Memory, and Disk (i/o) utilization after the process has completed using time (or another command if necessary). How can I accomplish this? Mainly I am using this to benchmark MySQL import performance using different innodb_buffer_pool_size settings.

  • Dovecot 2.x unix_listners

    - by Matthew Brown
    Could somebody be able to explain to me what the various unix_listners do in the Dovecot 2.x configuration (specifically 10-master.conf). Currently, for postfix to use to deliver mail, I have: service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } and for auth I have: service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { mode = 0666 user = vmail } } So what does each one specifically do? Also, does somebody know of a resource that can explain the mode setting?

    I'm looking for a clear answer for this English grammar question: Why do we write: The UCI Road World Championships 2012 (when the year mentioned) The Republic of India (when there is only one nation) but NOT The India?

I know the answer: The grammar usage is Definite Article but I'm looking for a clear explanation to this question. Thank you

  • How to monitor traffic on certain ports with ntop

    - by Claudiu
    How to configure ntop so I can get the amount of upload traffic sent through a certain port ? I've added port in ntop/protocol.list, restarted ntop and after some time I've checked Summary - Traffic - TCP/UDP Traffic Port Distribution: Last Minute View, but data from that table is not too relevant. I think there is much more about this ntop that I don't know (configuration, usage).

    On this page: http://tomcat.apache.org/tomcat-7.0-doc/jndi-resources-howto.html it describes how to set up a JNDI name for a DataSource resource.

Where is it?

  • How to route certain applications through a VPN and others to use my 'standard' connection in OSX 10.6?

    - by Alfie
    I am currently working abroad and use my company's VPN for FTP and some browsing. This is a relatively slow connection and while it is suitable for those VPN necessities; much of my other internet usage can be done without the VPN at a much higher speed. Is there a way to tell Safari and my FTP software to use the VPN and for all other connections to go directly to the internet. I am currently using OSX's Network Prefs for running my VPN connection.
