我以前没有使用过 SSH，所以我可能做错了什么。我正尝试通过 SSH 连接到虚拟机。在我运行的虚拟机上，ip a | grep inet它提供了以下输出：
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
inet 10.0.2.15/24 brd 10.0.2.255 scope global dynamic noprefixroute enp1s0
inet6 fec0::71ba:9fda:943b:113a/64 scope site dynamic noprefixroute
inet6 fe80::afca:876f:1e52:40fb/64 scope link noprefixroute
我在另一台机器上运行它ssh -v 10.0.2.15并给出以下输出：
OpenSSH_8.9p1 Ubuntu-3ubuntu0.1, OpenSSL 3.0.2 15 Mar 2022
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 19: include /etc/ssh/ssh_config.d/*.conf matched no files
debug1: /etc/ssh/ssh_config line 21: Applying options for *
debug1: Connecting to 10.0.2.15 [10.0.2.15] port 22.
这就是它所做的一切。如果我运行 ssh 时没有使用详细标志，它不会打印任何内容。终端被锁定，我必须使用 ctrl+c 终止该进程。我做错了什么，如何使用 ssh 连接到此虚拟机？
运行命令 ping -c4 10.0.2.15 得到以下输出：
PING 10.0.2.15 (10.0.2.15) 56(84) bytes of data.
^C

该命令ssh -vvvv 10.0.2.15给出以下输出：
