Ooooo, carajo, its a socket connect() problem !

I just put the last lines.. : socket(PF_INET, SOCK_STREAM, IPPROTO_TCP) = 48 bind(48, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("0.0.0.0")}, 16) = 0 connect(48, {sa_family=AF_INET, sin_port=htons(111), sin_addr=inet_addr(" 127.0.0.1")}, 16) strace is a real geek command. Is that how some begin reverse engineering? Anyway..Hmm..I don't see why socket problem..:-) I didn't intall udev..! See u.
