Study Help

Hi all, am just one of those million computer geeks out there that do happen to blog randomly about Cisco and Linux world. I started of this blog to brush up my knowledge and also thought it might be a bit of help for some stranded surfer who do eventually happen to end up reading this blog. I've taken of most of my previous posts in an urge to revamp this blog and give it a new structure. I will try to coverup some of the basics of networking or rather Cisco network ing with the perspective for CCNA. Location: Winter Ave,Stratford,United Kingdom

  Configuring passwords on the cisco IOS: Protecting privilege mode: Option I DeviceName(config)#enable password XXXX Option II DeviceName(config)#enable secret XXXX NOTE: Using “Option I” is not recommended as it stores password in clear text that can easily be tracked. Whereas “Option II” saves password in encrypted format. If both passwords are set, IOS uses secret password. Space Bar is counted as a character in password. Protecting user mode: DeviceName(config)# line console 0 DeviceName(config-line)#password XXXX DeviceName(config-line)#login Setting up Telnet: NOTE: This applies after successful IP configuration of the VLAN1 with valid IP address. DeviceName(config)# line vty X Y X = First line number and Y= Last line number. i.e. the number of allowed concurrent telnet sessions. DeviceName(config-line)#password XXXX NOTE: telnet will not work without any password. Keeping an eye on telnet session: DeviceName#termial monit...

The word "Virtualization" on its own, is too wide to discuss. But to cut it short, its a process of making one thing look like another. For our purposes we are referring to the ability of a computer to be split into multiple parts where the parts are (relatively) indistinguishable from the whole. For example, running different Linux environment on a single machine. Virtualization is often posed as a tool to over ride accustomed practice to having dedicated environments for each application, due to this one application per server deployment model, the majority of systems are grossly under-utilised like CPU utilization below 10% is normal. By virtualizing the physical hardware so that many “servers” can run simultaneously on the same physical machine we can drive utilisation much higher, to 50% or more. Hope it help!

Hi, Actually, an incident at work with one of my friend has prompted me to write this. With out going into much details, I'd quickly like to tell all the readers out there that mounting an windows NTFS partition is quite possible in Linux (RedHat). All you have to do is to install the following components: Firstly, install the FUSE-xxx version. Can be downloaded from http://fuse.sourceforge.net/ It also has a detailed explanation of procedure. After successfully installing the FUSE package, look for the " NTFS-3g" . It can be downloaded from http://www.ntfs-3g.org/ And also comes with detail explanations of installation procedure. After finishing installation of the above two packages following command will sort out all your problems: # ntfs-3g /dev/(device) /(mount point) Will mount the ntfs partition on the targeted directory. NOTE: Don't put entry in the fstab, as it will fail. can put the above comand in "rc.local"  for automati...
