  • Postfix as mail relay for web servers?

    - by Ben Carleton
    Hi all, I want to set up Postfix to relay mail from a group of webservers. I would like to limit senders by IP so I can restrict the box to only my webservers, so I don't have an open relay and don't have to worry about authentication. So, what I guess I need is to limit inbound access but allow mail to be sent to any outbound address. I've looked through the docs and don't even know where to start, so any tips would be appreciated. Thanks!

  • Windows Server 2003 port forwarding

    - by Vitor Braga
    Using the "netsh interface portproxy" I added a port forwarding to a Windows Server 2k3. The command "netsh interface portproxy show all" shows the added forwarding. On the other hand, any client connecting to the incoming port will receive a "connection refused" message. netstat also doesn't show the incoming port as listening. The machine firewall is disabled. There is any other way to setup port forwarding on Windows or debugging tips?

  • How should I use my new SSD drive?

    - by jasondavis
    I just built a new PC the other day. Specs... Processor: Intel i7-930 quad core CPU CPU Cooler: COOLER MASTER Hyper 212 Motherboard: AsRock X58 Extreme 3 RAM/Memory: 6gb G-Skill tripple channel DDR3 memory (3 sticks of 2gb planning to get another kit to make it 12gb total soon) Operating System Hard drive: Intel X25-M 80GB Mainstream SATA2 Solid State Drive Video Cards: 2 XFX ATI Redeon HD 4650 cards to run 3-4 monitors Case: Lian Li PC-B10 Midtower case Power Supply: Antec TruePower New TP-750 Blue 750W Operating System Windows 7 Pro 64bit Not sure if the specs are helpful at all but I posted them just in case. So I got everything put together and running great so far but I need some advice/ideas/help/tips. I got the SSD drive in hopes of using it strictly for my windows 7 install along with all my other programs I install. I am then going to get another drive or 2 just for data (video,music,photos, etc). So my plan is to just install the new data drives and then in windows 7 I will change my "My documents" "My Music" "My Video" "MY Photos" library's to be located on the data drives instead of the OS SSD drive. I would ultimately like to install all my programs with my windows install on the SSD drive and then create an IMAGE of the drive and then 6 months down the road if things are sluggish I can just wipe the drive and restore my IMAGE with all my programs and settings in tact still. So here are some questions now. 1) How can I verify that TRIM is working on my new SSD? 2) Is there anything above that I missed that I should be doing? I think I once read that there is a page file or some sort of file that windows changes a lot and that it should be moved off f an SSD an onto my data drives. DOes anyone know what I might of heard? If you do can you explain the pros and cons of doing such a thing as well as how to possibly? 3) Any tips or advice to get the best performance from all this, I built a pretty nice system and I just want to make it stay that way as long as I can.

  • Recommendation for a touch-enabled dev laptop

    - by Clay Shannon
    I don't keep up with hardware much, so would appreciate any tips on what would be a good touch-enabled laptop that I could use for both development and testing of Windows 8 ("Metro"/Store) apps. Is there even such an animal (a touch-centric laptop)? Or will I need to use a laptop for development (in which case I might be able to upgrade my RC version of Windows 8 on my existing laptop to RTM) and purchase a tablet for testing?

  • Want to create an SQL function that removes table row duplicates [migrated]

    - by Hoser
    I'd be following the procedure outlined here (unless of course someone has a better way to do it), and I'm wondering if I could just have some help being pointed in the right direction on how to start. Basically I need help first on HOW to create functions, and general tips on making it adjustable for varying number of columns etc. This may be a very complicated task, as I have no previous experience making SQL functions, so please let me know if this is a difficult task for an SQL noobie working with MS SQL 2005.

  • Apache not finding index.php by default, set rule for routing through index.php

    - by eoinoc
    Apache on the server is set to find index.php by default, and that works for a normal folder. However, I have a .htaccess rule to route all requests through my routing script: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php [QSA,L] With these .htaccess contents, the server returns a 404 error. Only by specifying /index.php does the routing script get called. Any tips on what I am doing wrong?

    - by splattne
    Computer cables and external devices are a continuous source of frustration for everybody who likes a clean working environment. The more devices you add to your home office, the more disastrous the situation under the table becomes: cords falling behind the desk, ugly cables running along the sides and under of the desk, making it almost impossible to clean and remove the dust. This is not my office, but I've seen similar "setups:" I'm looking for good tips/products which help me in keeping the all cables somehow under control and organized.
