新装的rh el5无telnetd进程，用来启动xinetd的程序也没有，手工启动telnetd报错

新装的rh el5无telnetd进程，用来启动xinetd的程序也没有，手工启动telnetd报错：

[root@mecc ~]# telnetd

telnetd: getpeername: Socket operation on non-socket

使用telnetd -debug可以启动，当连接过一次tlenetd就自动退出

 

 

---需要安装使用inetd/xinetd服务连接器来启动telnetd

The problem may be that you are all trying to start in.telnetd from the console. But it must be started by inetd/xinetd ! Inetd receives a socket and then does the following:

Code:

 

close(STDIN_FILENO);

close(STDOUT_FILENO);

close(STDERR_FILENO);

dup2(sock, STDIN_FILENO);

dup2(sock, STDOUT_FILENO);

dup2(sock, STDERR_FILENO);

 

so the in.* programs may communicate using the standard I/O calls or read/write. When you try it from the command line, it tries to get the client address using getpeername(STDIN_FILENO, ...) but it's connected to a pseudo-tty. Try better with "kill -HUP `pidof xinetd`"
