[En-Nut-Discussion] Ppp user/pass

[Lorenzo Lombardo]

There's a little error, change

pppStr = (char *) malloc(strlen(pppCom) + strlen(pppUser) + 
strlen(pppPassword) + 9);

with

pppStr = (char *) malloc(strlen(pppCom) + strlen(pppUser) + 
strlen(pppPassword) + 7);

because the null char at the end of the string we are going to make is one.
