Unix Active Directory Software Faster - PCWorld. Likewise Software has released a new version of its open-source authentication software for allowing Linux, Apple Macintosh and commercial Unix-based computers to hook into Microsoft Active Directory controlled servers and networks.
Version 6 of this open-source software speeds the client log-on time and works better in large, complex environments, according to Gerald Carter, director of engineering for Likewise. The upgraded software also comes with an improved service manager and installation manager as well. When installed on Macintosh, Linux or Unix computers, Likewise Open can allow users to sign onto a network whose access is controlled by Active Directory.
The software also includes a management console for administrators. The client software uses the same protocols that a Windows machine would use to interact with Active Directory, including Kerberos and the Lightweight Directory Access Protocol. In version 6, client log-ins should take less time, Carter said. Samba. Samba is an implementation of the Server Message Block (SMB)/Common Internet File System (CIFS) protocol for Unix systems, providing support for cross-platform file and printer sharing with Microsoft Windows, OS X, and other Unix systems.
Samba can be used to: Authenticating Linux against Active Directory. If you are planning to use a Linux workstation in a Windows Network, one of the things you probably want to do is authenticate against the Windows Domain name server (s), i.e.

From DD-WRT Wiki OpenDNS is a free DNS (Domain Name Server) service which makes internet browsing safer and allegedly faster.
By simply using their DNS servers instead of your ISP's you are automatically protected from their list of Phishing websites. However, in order to restrict a variety of adult website content you will need to create a free account with them, register your IP address and select the categories you want restricted (i.e. sexuality, nude, pornography, lingerie, grotesque, etc...). Since most of us have DHCP assigned WAN IP addresses that change periodically we need to instruct our router to tell OpenDNS what our new IP address is when it changes. We will go over that below. [edit] Basic Setup In order to configure dd-wrt with OpenDNS you need to specify the OpenDNS DNS servers in the control panel. Option 1 - Configure DHCP with OpenDNS DNS server If you want the DNS servers to be queried in the order they're listed rather than randomly: Click Apply Settings. Packet Life.

Monitor Your Monthly Bandwidth with Your Router. Port number. In computer networking, a port is an application-specific or process-specific software construct serving as a communications endpoint in a computer's host operating system.
A port is associated with an IP address of the host, as well as the type of protocol used for communication. The purpose of ports is to uniquely identify different applications or processes running on a single computer and thereby enable them to share a single physical connection to a packet-switched network like the Internet. The protocols that primarily use ports are the Transport Layer protocols, such as the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) of the Internet Protocol Suite.

- If you forgot to set your "boot_wait" nvram setting and uploaded a bad firmware image which caused your router not to boot (like I did) - You failed every other instruction for reviving your router - You like living on the edge and just wanna play Pros: Turn your black and blue paper weight back into a working wireless router. Cons: I suppose you could make your WRT54G even deader than it already is, although I have not actually heard of anyone who has done this. The pictures in this tip are for people who have the v1.1 hardware. Web interface for OpenWrt and more - X-Wrt.org. Kamikaze images for Linksys WRT350N. Author Topic: Kamikaze images for Linksys WRT350N (Read 4035 times) The stock x-wrt or openwrt images do not work on WRT350N because they do not contain the drivers for the ethernet switch or wireless. As a result flashing with these images bricks the router. I rebuilt the images with the required drivers and uploaded it here if anyone is interested: Note that these are only kernel 2.4 images with the proprietary drivers (I have not gotten 2.6 images to build yet).
Linksys WRT54GS. The original WRT54G was first released in December 2002. The router is considered a home network device supporting, WLAN( ), LAN and WAN . It has a 4+1 port network switch (the Internet WAN port is part of the same internal network switch, but on a different VLAN). The devices have two removable antennas connected through Reverse Polarity TNC connectors.

First and foremost you need to get your hands on the coolest free BSD system for firewalls and security devices. In this example I will be using OpenBSD3.6 stock standard as a build and a base system (but I guess you could use FreeBSD5.3 – me thinks the newer FreeBSD are getting a bit bloated but the background fscking, fscking rocks dude!) Once you have installed your neighborhood OS in your server (go ahead and install all the packages from the OpenBSD installation CD, heck I have 40G worth of SATA drive on my brand spanking new Dell 1U server so I don't really care) you only need to change a couple of files within your /etc directory before you can start rocking. The Setup By the way my rig is a Dell 1U server with 4 NIC cards and a lot of RAM.
The ultimate goal is to have 2 internal network segments and 1 uplink to the Internet. /etc/rc.conf.local.
