我想让SSH去跳服务器。从jumpserver，我想要SSH到主机并执行一个命令：'rpm -qa \ grep包‘并获得输出。完成后，我希望首先成功地注销主机，然后注销跳转服务器。
以下是我迄今所做的尝试：
Import pexpect
options = '-q -oStrictHostKeyChecking=no -oUserKnownHostsFile=/dev/null -oPubkeyAuthentication=no'
child = pexpect.spawn('ssh ssheth@jumpserver %s'%(options), timeout=None)
child.expect(['password: '])
child.sendline('hello123')
child.expect('#')
child.sendline('ssh ssheth@host "rpm -qa | grep -v watch | grep extractor"')
child.expect(['password: '])
child.sendline(password)
child.logfile = fout
child.expect(".*\$ ", timeout=None)
child.close()这会引发以下异常：
Timeout exceeded in read_nonblocking().

最简单的答案是打开一个端口转发到远程服务器。
这在bash中效果最好，但您可以进行子进程，也可以通过python运行它。
假设IP是：
- jumpserver IP为151.121.121.121
- 最后服务器IP为10.1.2.3。
如下所示
# Open a local port 13000 that will map through jumpserver and
# connect to finalserver on port 22
ssh -L 13000:10.1.2.3:22 username@151.121.121.121
# Then open an ssh session to localhost:13000 (which will forward to the
# finalserver.com and run your command)
ssh username@localhost -p 13000 'rpm -qa | grep package'Stack Overflow用户
