我在专用服务器上尝试
root@debian:~# strace -e open -f sshpass -p guest ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null [email protected] -C -N -D 127.0.0.1:22220 -f
[pid 10451] open("/dev/tty", O_RDWR) = 4
[pid 10451] open("/dev/tty", O_RDWR) = 4

没关系
我尝试在 virtualbox 或 qemu 上安装 debian 7.7 x64
root@debian:~# strace -e open -f sshpass -p guest ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null [email protected] -C -N -D 127.0.0.1:22220 -f

为什么 ssh 隧道在 virtualbox 或 qemu 上不起作用？ssh tunel 在 virtualbox 或 qemu 上使用选项-vverbose 可以工作，但使用选项 white 则-f 不起作用
