Unhappy How do I compile a code snippet. to test my box??


How do i compile some code. Im using Redhat 7.1 and i have another Box wich is using windows, on which my webserver is on, and im using sambar. Now i want to compile this code cut n paste, so i can test this vulnrability of my windows Box. but i dont know how to, i have tried saving it in a text file but with the extension .c .cpp then tried compiling with gcc but.it doesnt work. Or am i being totally stupid(probally) and is the code already compiled?? if so how do i use it, ( run it) many thanks. here is the code.

First get rid of underscores
Quote:
____
__int sd, rc, i,j;
__char buf[5000];
__char msgtosnd[5024];
__char msgtoget[102400];
__char source[200000];
__struct sockaddr_in localAddr, servAddr;
__struct hostent *h;
__FILE *f1;
__
make it look
Code:
int sd, rc, i,j;
char buf[5000];
char msgtosnd[5024];
char msgtoget[102400];
char source[200000];
struct sockaddr_in localAddr, servAddr;
struct hostent *h;
FILE *f1;
then where you want it compile in linux
use the basic gcc
gcc -o test.exe test.c

And make sure you have gcc installed:
rpm -q -a|grep gcc

well i'm not going to debug the code
but i guess the gcc reports no errors?
look if it produced an a.out or ....out
do a ./ a.out to see if it works
gcc -o nameyourprog name.c spits out the name you want
try for testing some simple prog like the Hello World!
prog thats described in all c tutorials
enjoy
since i'm not a 'real' programmer, hope this fits

** yes go for Mara's suggestions see timestamp **
