2K admin now RHEL4 admin (I have some questions)
Hello, I am a Windows 2000/2003 admin who has found himself a RHEL4 admin over night. Our company just purchased a Linux cluster and I am now responsible for it. Luckily I have a small understanding of Linux because I maintain a proxy server running Squid, on top of Fedora (Core 2). I know enough to be able to log into the system, edit a ban list file and an allow list file and restart the service. Not quite the same as maintaining a Linux cluster.
The cluster is going to be used for crunching numbers and not running any server related tasks.
I would like the one or two people who will be running the number crunching program to be able to interact with the system in a GUI, remotely. Is there anyway that RHEL4 will accept a terminal services connection? I noticed that there was a terminal server client installed on the system, but did not notice a terminal server service available. If I am unable to connect to the system with terminal services, what is the recommended way of remotely connecting to the system and interacting with it using a GUI. The remote connection will be initiated from a Windows XP computer.
I am under the impression that a Linux system can join a Windows 2000/2003 domain if it is running the latest version of SOMBA. Is this correct? Is this advisable to do? If I join this Linux cluster to my Windows 2000 domain, can I use my domain to authenticate the users who are connecting remotely to the system (A terminal services style connection.)?
On a slightly different topic, I have a network card question. At the command prompt In Windows I can type “ipconfig /renew” to force the computer to try and renew its IP lease from a DHCP server. I know Linux has the command ifconfig that allows you to view much of the same information as Windows ipconfig, but I could not find a way to renew the IP address lease. Does anyone know how I might do this?
Thank you very much for your time,
