我尝试在专用的服务器上
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 debug1: Enabling compression at level 6. debug1: Authentication succeeded (keyboard-interactive).

我试着在virtualbox或qemu上安装的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 Warning: Permanently added '198.51.100.11' (RSA) to the list of known hosts.

为什么SSH隧道不能在virtualbox或qemu上工作？ ssh tunel在virtualbox或qemu上运行选项-v冗长，但是whit选项-f不起作用
