  • Resources for a new Windows Small Business Server administrator?

    - by 80bower
    I've recently taken over management of a Windows 2003 Small Business Server and network for a small, less than ten person company. I have some (antiquated) sysadmin experience, but I've little experience with Exchange. The documentation of the existing infrastructure leaves much to be desired, and I was wondering if there's any sort of "So you've just become sysadmin" guides that anyone could recommend.

  • Routing domain over lan [closed]

    - by Buri
    I have server on my local network which is exposed to the internet. I have domain pointed on my IP and setup forwarding. The thing i would like to do is when i access example.com from lan to connection be routed directly on my server, not to the nearest DNS. Things I had in mind were to upgrade router with dd-wrt and setup routing rule, or to setup local DNS. Unfortunately, I'm not familiar with neither of those systems.

  • 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.....

    - by user1233963
    What I'm trying to do is set up a udev rule for my HP headphones (usb) with the aid of several tutorials out there. Created a file ( 90-local.rules ) in /etc/udev/rules.d and added the following: ACTION="add",SUBSYSTEM="usb", ATTR{vendor}=="Hewlett-Packard", RUN+="sh /home/alex/Scripts/usb.sh" The problem is nothing happens when I connect the headphones! What am I doing wrong? note: I did restart udev and the script works also, so it's not that

  • Locked out of windows 7 pc

    - by Fasih Khatib
    This is a question on behalf of my friend. His kid brother installed a password on his windows 7 home premium desktop and now he forgot. How does he get in? Since the data is backed up into a flash drive, i suggested nuking using DBAN and reinstalling OS. To complicate matters further, his CD drive doesn't work. In that case, what options does he have available to recover his password? Can DBAN be run from a bootable pendrive?

  • rhn_register through HTTP Proxy with Authentication

    - by kjloh
    Is there any limitation to the proxy authentication support of rhn_register? The proxy of the network I'm on sends the follow 407: HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. ) Via: 1.1 VANESSA Proxy-Authenticate: Negotiate Proxy-Authenticate: Kerberos Proxy-Authenticate: NTLM It seems that rhn_register is not able to any of the authentication schemes above. Any advise?

  • 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.

  • Wake On LAN on request [closed]

    - by honzas
    Hi, I have a small home network with the router capable of running OpenWRT, is there some utility or firewall rule, which can be used to Wake On LAN on request. What I think - if I want to access my media centre (using for example SSH or HTTP) and it is suspended, is it possible to catch the ICMP packet (saying the machine is offline) and send the WOL packet to wakeup the machine and resend the SSH or HTTP request? Thanks

  • Windows 7 keeps asking for WIFI credentials

    - by RubenGeert
    If I want to log onto our WIFI network, Windows keeps asking for credentials. After many connection attempts (and sometimes some reboots) we finally manage to connect. Then the connection usually stays intact for the rest of the day. But it sometimes takes 15-20 minutes before we're online... Needless to say we're using a single username/password for all failing/succeeding attempts. Does anybody recognize these symptoms? How to troubleshoot this?

  • VirtualBox OSE: Install Guest OS On Headless Host Via VNC?

    - by Eddie Parker
    I've remotely installed VirtualBox OSE on my Gentoo box at home. I have everything set up and ready for the OS. However all the documentation I've read seems to say that you can only use the PUEL version in order to get remote access during installs - does anyone know if it's possible to do similar with the OSE but using VNC? Links to documentation or tutorials would be welcome, apparently my Google-Fu is failing me, if it's out there. Thanks.
