Hi, I have a couple of question:
1. A technique for an intruder to keep a root account was creating a stuid
root shell, that is not possible on FreeBSD nowadays, Why is not possible?
How a program like sudo can do that? Foe example, If i am a sudo 'full
admin' I can do this without passwd:
%sudo su
#
2. I coded a program that read a wordlist and prints them:
char str1[64];
...
while(!(feof(FooPtr)){
fscanf(FooPtr,"%s\n",str1);
..
printf("%c",str1[x]);
...
If the "character" I going to printf is alpha or numeric, there is NO
problem, but if i am going to print an space, it core dumps...
Why this happens?
How can I solve this?
FreeBSD rules forever!
