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

ps 显示所有进程, 看 dropbear 有没有在跑。

这个日志 Starting dropbear sshd 应该是
/etc/init.d/XXX 开机初始化脚本里面显示出来的, 找到对应的dropbear 命令行修改一下。
dropbear 命令行我记得有后台运行的参数, 你找一下。
