can anyone help me to make an auto pinging program with C?
im trying to make a program that ping a computer continuously so that i knew when that computer is down. i want to add the result of ping to a file. it should be better that the program doesn't use things like bash shell or something, i don't know the name
thanks very much

Why not use a shell script. This is perfect solution for this.

Hi astoristz,

I have to agree with Squashman that a shell script would be easiest solution for this problem without more details.

Perhaps you could explain the context for the use of the program. If it only involves you at a desktop and is not a part of some application, then the shell approach is probably best. On the other hand, if it is to be a part of an application that is already coded in C, then C would be the way to go.

Bash understands sh, and zsh, and you can certainly specify the shell language inside the script you or someone else writes.

Perhaps even easier is if you know the IP address of the computer you want to ping, then inside your shell, you can make an alias to do the ping for you. As an example, inside your shell: This example assumes the csh is used:
In the file residing in your $HOME directory that is named, ".cshrc", put the following line:
alias poke "ping <ipaddress>"

and substitute the real ip address of the computer for <ipaddress>.

Then from your shell window, just issue the poke command (assumes poke is not a command available in your shell $PATH), as in:

$ poke

which your shell then replaces with "ping <the ipaddress you substituted>" before it executes the ping command.
