i use busybox-1.0-rc for my board and i want to run telnetd in buysbox on the target(192.168.81.100), in start with command:$telnetd and on host, &telnet 192.168.81.100, it show as follow: telnet Trying 192.168.81.100... Connected to 192.168.81.100 (192.168.81.100). Escape character is '^]'. Connection closed by foreign host. on the target i use netstat to check $ netstat -l Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 *:23 *:* LISTEN udp 0 0 *:800 *:* Active UNIX domain sockets (only servers) Proto RefCnt Flags Type State I-Node Path in my rootfs it has /etc/passwd, group login, telnetd is also in busybox. and i also have add devfs both for kernel and busybox do i miss something? maybe need any other service for telnetd? thanks for any hints Best Regards! zhuzhenhua
