我是网络相关的新手,我想通过另一台服务器(隧道)访问远程客户端, 例如,用户名为user2和password2的远程客户端11.11.111.111,以及用户名为user1和password1的隧道11.11.10.01
我可以成功ping通地址隧道地址。 但是当我尝试使用cygwin访问远程客户端时:
ssh -vv -o 'ProxyCommand ssh -vv user1@11.11.10.01 nc %h %p' user2@11.11.111.111
我收到此错误:
OpenSSH_6.4, OpenSSL 1.0.1f 6 Jan 2014

ssh: connect to host 11.11.10.01 port 22: Connection timed out

我的命令是否正确,有关可能原因的任何想法?
有哪些方法可以排除故障(最好是在我的机器上,而不是在服务器和远程客户端上)?
答案 0 :(得分:1)
我认为这只是一个部分答案,但尝试用ssh连接到11.11.10.01:
ssh user1@11.11.10.01 -L20022:11.11.111.111:22
然后在另一个窗口连接通过:
ssh user2@127.0.0.1 -p20022
通过这种方式,您将在第一个终端窗口中收到错误。
