Explain network configuration files in /etc/sysconfig/network-scripts.

41.Explain network configuration files in /etc/sysconfig/network-scripts.
Ans.
1. We can use the files in this directory to set the parameters for the hardware and software used for networking.

 2. These scripts are used to enable network interface and set other network-related parameters.

 3. Ifcfg-networkinterfacename
Red hat specifies a separate configuration file for each network interface.
In typical Red hat install, we have many different network interface configuration files that all follow the same basic syntax and format.

 4. ifup and ifdown
These files are symlinks to /sbin/ifup and /sbin/ifdown, these scripts are called when the network service is started or stopped.
We call the scripts with the name of interface that we want to bring up or down.
For instance, to bring Ethernet interface down and up again after boot, we will type command
Ifup eth0
Ifdown eth0

Explain memory and virtual file system in Linux.

By
22.Explain memory and virtual file system in Linux. Ans. 1. These file systems do not exist on disk in the same way that traditional file systems do, they either exists entirely in the system memory or they are virtual because they are an interface to system devices. 2. cramfs: cramfs is designed to cram a file System onto a small flash memory device, so it is small, simple and able to compress things well. The largest file size is 16MB and the largest file system size is 256MB since cramfs is so compressed, it isn’t instantly updateable. 3. tmpfs: tmpfs is structured around the idea that whatever is put in the /tmp file system is accessed again shortly, tmpfs solely in memory, so what you put in /tmp doesn’t persist between reboots. 4. ramfs: ramfs is basically cramfs without the compression. 5. romfs: This is a read only file system that is mostly used for initial ramdisks of installation disks. It was designed to take up very little space, so you could fit a ke...
