1.NAP Network address translation (NAT) is a method of remapping one IP address space into another by modifying network address information in Internet Protocol (IP) datagram packet headers while they are in transit across a traffic routing device.[1] The technique was originally used for ease of rerouting traffic in IP networks without readdressing every host. In more advanced NAT implementations featuring IP masquerading, it has become a popular and essential tool in conserving global address space allocations in face of IPv4 address exhaustion by sharing one Internet-routable IP address of a NAT gateway for an entire private network. 2.DMZ n computer security, a DMZ or demilitarized zone (sometimes referred to as a perimeter network) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to an untrusted network, usually a larger network such as the Internet. The purpose of a DMZ is to add an additional layer of security to an...

'>' is for redirection '/dev/null' is a black hole where any data sent, will be discarded '2' is the file descriptor for Standard Error '&' is the symbol for file descriptor (without it, the following 1 would be considered a filename) '1' is the file descriptor for Standard Out $ cat foo.txt foo bar baz redirection is the mechanism used to send the output of a command to another place. Here, for example, we are redirecting it to a file called out.txt: $ cat foo.txt > out.txt we could rewrite the command like this: $ cat foo.txt 1> out.txt we don’t see any output in the screen. We changed the standard output (stdout) location to a file. $ cat out.txt foo bar baz if we try to cat a file that doesn’t exist, like this: $ cat nop.txt > out.txt cat: nop.txt: No such file or directory we see the error output in the screen, because we are redirecting just the standard output, not the standard error. Using std...

We can use nohup and send a long running command to background. We can continue while the command will keep on executing in background. After that We can safely log out. With nohup command we tell the process to ignore the SIGHUP signal which is sent by ssh session on termination, thus making the command persist even after session logout. On session logout the command is detched from controlling terminal and keeps on running in background as daemon process. Here, is a simple scenario wherein, we have run find command to search for files in background on ssh session using nohup, after which the task was sent to background with prompt returning immediately giving PID and job ID of the process # nohup find / -type f > files_in_system.out 2>&1 & Resuming the session to view if job is still running When we re-login again, we can check the status of command, bring it back to foreground using 'fg jobID' to monitor its progress and so on. Below, the out...
