comment Wireless connected but no connection
How old is the laptop (?) you're using? Does this happen if you plug in a new(ish) USB writeless card? I'm told that the low-noise amplifiers on wireless cards can degrade with time.

comment Can't find connected devices on wifi network
Give us some help, here. Show the output of "ifconfig wlp12s0" or whatever your wireless device is, or the output of "ip link". Show us the nmap command line. Show us the output of ip route. Tell us what brand of wireless router you've got going, and what it's running (DD-wrt, OpenWrt, what?), and what it says are the connected devices. You're not telling us enough to help at all.

comment How to get new ip using dhcpcd
You do know that it's possible for the DHCP server to always give the same IP address to a given hardware (MAC, ethernet) address, right? I have my home network's dhcpd configured to give a printer the same IP address every time. No amount of fiddling with dhcpcd will change that, you'd have to change the interface's MAC address.

comment routing problem - arp
Add some information to your question. Do ifconfig tun3 and ifconfig virbr1 and put that on your question. As your question stands, there's no way to answer it.

comment Is the return value “-1” of the function socket close() method possible?
If the code I write is explicitly single-threaded, are there "background" threads (for lack of a better word) that execute without my code starting them? That is, in a program that never calls pthread_create(), should I think about the EINTR situation with respect to closing a file descriptor?

comment Why signal function is not able to call my signal Handler?
@Kalu - if you had your child process doing a getppid() system call, you might catch PID 1 as the parent PID, if the forking process exits fast enough, and the kernel's scheduler cooperates.

You could also use the pause() system call instead of sleep(), to allow time to do a few ps -ef and check PID -> PPID relationships without hurry.

comment Bash script strange behavior - script does not act as manual commands
This looks like you've got some difference in environmental variables or their values between your login shell, and the /bin/bash that runs the script. Can you run printenv in a script and see if that matches printenv output from the interactive (login) shell?
