Wow, yes i CAN make it ...

How do I set advanced security options of the TCP/IP stack and virtual memory to improve security and performance of my system? How do I configure Linux kernel to prevent certain kinds of attacks using /etc/sysctl.conf? How do I set Linux kernel parameters?

sysctl is an interface that allows you to make changes to a running Linux kernel. With /etc/sysctl.conf you can configure various Linux networking and system settings such as:

1. Limit network-transmitted configuration for IPv4
2. Limit network-transmitted configuration for IPv6
3. Turn on execshild protection

Imagine that we have a server running RHEL 4 and our supervisor comes over and wants a 10 GB partition created for the data processing department. This is in addition to what the server currently has allocated, so we can either create a partition out of unpartitioned space on the existing disk (experienced Linux system administrators will leave unpartitioned disk space for future expansion) if available, or we can add another drive.

There's an enormous difference, actually. There's really no such thing as a "hard link". If anything, there is an action that you can call "creating a hard link".

The thing is, a file can have several names. If you create a hard link (by running `ln' without `-s'), you simply create a new name which points to the exact same file as the original name. For example, if you run the following commands:

Code:

cd /tmp

echo test >file1

ln file1 file2

Making a script run at boot time needs certain consideration and configuration.The Startup script are usually under /etc/init.d directory.
Some Admin think that by just putting the script under /etc/init.d will make it run as service.
No !! The Story is little different.

Say, I have a script called myscript which I want to run as service either:

/etc/init.d/myscript [restart|reload|start|stop]
or
service myscript start

But little more steps are usually needed.
I am talking about Red Hat Distribution but may run comfortably in other *nix too.
