problems generate a random file

[Benjamin Scherb]

Hello All, I have to set up the freeradius server on Gentoo to secure my home WLAN. I prefer to use the EAP-TTLS and found an very good howto: http://rbirri.9online.fr/howto/Freeradius_+_TTLS.html In on of the section at the howto there is a discription on how to setup up a short C programm to enerate a random file. But I do not understand how I should generate this file. Here are the information included from the how to above: ##################################################### Third step To generate a random file you will need a short C program using openssl libraries. #include <stdio.h> #include <openssl/rand.h> // you will need to compile it with openssl lib // $ gcc -lcrypto main (void) { unsigned char buf[100]; if (!RAND_bytes(buf, 100)) { // the usual md5(time+pid) } printf("Random : %s\n", buf); } Compile it with : gcc random.c -o random -lcrypto I will generate 32-bit LSB executable named random, try it with ./random. Move this file to /etc/mycerts/ mv random /etc/mycerts/. ##################################################### Can anyone help me to generate the needed random file? Many Thanks. Best Regards, Benjamin
