buildroot 以太网问题

大家好, 我问一个小问题

我自己定制了buildroot,  只设置了链接器和安装了dropbear,  系统启动都正常,内网外网都可以ping的通, 我现在用dropbear开启监听,出现问题如下

# netstat -tln
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       
netstat: /proc/net/tcp6: No such file or directory
# 
# 
# dropbear -p 2222
# 
# 
# netstat -tln
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       
netstat: /proc/net/tcp6: No such file or directory
# 
# ping www.baidu.com
PING www.baidu.com (180.101.49.12): 56 data bytes
64 bytes from 180.101.49.12: seq=0 ttl=53 time=7.716 ms
64 bytes from 180.101.49.12: seq=1 ttl=53 time=7.628 ms
64 bytes from 180.101.49.12: seq=2 ttl=53 time=7.547 ms

我感觉端口打不开啊,  还是我缺什么配置了?   也不像缺配置了,按道理说系统刚启动时,我调用netstat -tln,怎么样也应该有点东西啊,我那个什么都没,昨天卡了一天了,请各位帮忙看看, 给点参考意见,谢谢了
