Try downloading VMWare server on the net. That is free and it can emulate multiple boxes( I am not starting a fire here on the choice of the virtual emulator but vmware is a good one to start with IMHO). Install linux and run atleast 3 instances with no two on the same network. Assign IP addresses and then try to do what all you can do with the data. VMWare gives you ease of use to add a harddisk and so you can just add another 2 hard-disks and try out DM-RAID or LVM, try occupying one lvm, move lvm data from one disk to other, recover from a lost level 5 raid etc., On the networking side, you can try pinging the linux boxes in the other networks using the linux box with 2 network cards as a router. Try changing and playing with the ip addresses using iptables , putting rules, blocking traffic etc., on the configuration sied, you can setup radius server, http server and then try to make then secure by adding some firewall rules which allow access to only one machine etc., and also setting up usernames and passwords for accessing a site in apache. But yes, make sure you are thorough with compiling kernels and making them work. Sometimes compilation and adding to grub goes like a breeze and sometimes you end up finding out what has to be put in the .config to avoid the kernel-panic while booting ! After this you can try out sysadmin things on the kernel side which may be something like installing a new kernel, trying to play with SCSI disks, etc., You can work on the booting process and try writing a /etc/rc.X init script which gets called during the bootup of the box from init scripts. Last but not least, get back to this group if you have isses and i am sure many people in the group will be glad to help you with your issues in linux. > -- Bhasker C V Registered Linux user: #306349 (counter.li.org) The box said "Requires Windows 95, NT, or better", so I installed Linux. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
