  • How faster is using an internal IP address instead of an external one?

    - by user349603
    I have a mailing list application that sends emails through several dedicated SMTP servers (running Linux Debian 5 and Postfix) in the same network of a hosting company. However, the application is using the servers' external IP addresses in order to connect to them over SMTP, and I was wondering what kind of improvement would be obtained if the application used the internal IP addresses of the servers instead? Thank you in advance for your insight.

    - by Investor5555
    Is it possible to copy an XP Mode Virtual PC image from one computer to a completely different computer (not on the network, not related in any way whatsoever)? I tried this, but it only would seem to work on the same computer: http://www.sevenforums.com/tutorials/21904-virtual-xp-machine-copy.html When I copy it to another computer and modify the settings as described above, the cursor just jumps around all over the screen and never starts.

  • How to control linux workstations- with poloices.

    - by redknight
    I am going to be administering a small network of linux based workstations for a charity institution (not all have the same distro- some are ubuntu and some are fedora). Is there something in Linux that is similar to group policy in windows?. For example I would like to standardize the wallpapers - have only firefox as a browser - default VLC as the media player etc etc. Thank you, any suggestions are very appreciated.

  • Configure Apache to use external proxy for internet connection

    - by warpech
    In my application I am using following rewrite rule: RewriteRule ^/ajax(.*) http://api.externalserver.com/$1 [P,QSA,L] You know what it does.

  • bridge traffic limiting via tc

    - by jackhab
    I have a Linux machine running as a bridge simulating various network conditions. I use tc for this. Introducing delays or packet loss is quite simple but I got into trouble trying to configure bandwidth limiting. Can you, please, show me how to limit all the traffic going through my bridge without any special rules and condition, simply limit it to 1Mb/s? Thanks. PS Your favorite link to tc tutorial will be appreciated.

  • Modem with support for wired 802.1x

    - by menko
    I'm looking at allowing internet access for only a few scattered users on a school network. One method I'm considering is using 802.1x authentication for the modem. Of course there are simpler options like only allowing specific IP or mac addresses, but policy requires something more secure than this. So, are there any modems with 802.1x wired authentication? All my searching on this yields info about wireless.

    I just inherited a G4 Server (I don't know much about it, except that it runs 10.4 and cannot go beyond that). It does not have an Airport connection. How would I figure out what kind of card or network interface I need for Wifi?

  • How would I recognize the "spoon-feeding problem" on a dynamic webapp server?

    - by Don Spaulding
    The "spoon-feeding problem", as it was recently explained to me, happens when connections to your application server are tied up feeding data across slow network connections to your clients. This makes sense to me and now I understand the importance of putting a highly-concurrent proxy in front of my app servers. My question is, how did the first person to recognize this problem figure it out? What *nix tools and troubleshooting techniques would help me to recognize this problem if I hadn't had it explained to me?

  • Data recovery for Mac

    - by josh3736
    I've got a Mac that won't boot and I'd like to recover whatever data I can before wiping the hard drive and reinstalling. I'm looking for something similar to TRK (which is Windows-centric) — boot from CD, mount the hard drive, and copy to a network share. I just noticed TRK does appear to support HFS+; has anyone had success with this?

  • BitTorrent Myth

    - by Moon .
    In BitTorent Statistics there is a field "Total Ratio" that is the ratio between total downloads and uploads. i have heard that this ratio affects BitTorrent'ss performance. If the ratio is better then BitTorrent Network provides you services on priority. And If the ratio is down (less uploads) then the BitTorrent provides you services on average or below average priorities. Is there something like that.....

  • slave dns server, resolv.conf configuration

    - by Tim the Enchanter
    I have two servers (a master and slave) running DNS (bind). What should the /etc/resolv.conf file look like for the master and the slave? For example should the servers running the DNS have only : nameserver 127.0.0.1 or should they refer to the I.P. addresses of each server, as the other servers on the network do : search <mydomain>.co.uk nameserver 192.168.1.52 nameserver 192.168.1.57

  • Can I connect two routers to one switch?

    - by vanneto
    I want to connect two routers to a switch which will then be connected to a modem. Now as far as I know a switch does not do network translation and this won't work with one IP address. So I bought two addresses at my ISP. Attached is a simple schematic that explains what I want to do. Is there any additional configuration needed on either of the routers (Linksys WRT54GL) to make this work or will it "Just Work"?

    - by Ernst
    Hi, I'm sharing a contact list with another user on the network, but I'm using outlook 2007 and the other user is using outlook 2003. The other user has assigned many different categories, but I do not get those categories added to the list of categories I can choose from when adding/editing contacts, I can see certain contacts have those categories. How do I add those categories so I can also add them? The shared contacts originate from the other user. Thanks
