使用 Powershell 和 SSH-Session 启动 openconnect VPN

Question

我需要从 Windows 上的 powershell 脚本在 linux 路由器上启动 openconnect VPN。

我在 linux 路由器上有一个工作脚本：

echo PASSWORD | sudo openconnect -b --no-dtls --interface=sslvpn host.isp.com --authgroup=SharedVPN --user=username --passwd-on-stdin

当我运行本地路由器上的脚本时，vpn 完美启动。这是我在 windows 机器上的 powershell 脚本：

Import-Module SSH-Sessions New-SshSession -ComputerName "10.1.43.11" -Username "ubuntu" -KeyFile "C:\keys.pem" Invoke-SshCommand -ComputerName "10.1.43.11" -Command '/usr/local/sbin/InitializeVPN' Remove-SshSession -computername "10.1.43.11"

当我运行 powershell 脚本时，它确实启动了 VPN，但冻结在那里，等待 VPN 结束。我可以终止路由器上的进程，然后 powershell 脚本完成。我需要在后台连接运行的 VPN。所以我像这样修改了路由器上的脚本：

echo PASSWORD | sudo openconnect -b --no-dtls --interface=sslvpn host.isp.com --authgroup=SharedVPN --user=username --passwd-on-stdin &

现在，当我运行 powershell 脚本时，它似乎确实将其发送到后台，但 VPN 无法正常运行，我只能在屏幕上获得部分输出：

Key file specified. Will override password. Trying to read key file...
Successfully connected to 10.1.43.11

10.1.43.11 should now be disconnected and disposed.

当我直接在路由器上运行它的时候，最后还有"XML POST enabled":

如何让 VPN 在后台启动？

我正在使用 ubuntu 16.04、openconnect 7.08、powershell 5.1、windows 服务器 2016，从 http://www.powershelladmin.com/wiki/SSH_from_PowerShell_using_the_SSH.NET_library#Downloads

好吧，我使用 plink 让它工作了：

C:\bin\plink.exe -i C:\key.ppk ubuntu@10.1.43.11 "nohup /usr/local/sbin/InitializeVPN >/home/ubuntu/VPN.out 2>/home/ubuntu/VPN.err </dev/null &"

stdin、stdout 和 stderr 必须重定向并使用 nohup。

我在这里找到它：Getting ssh to execute a command in the background on target machine

不知道我现在是否会花时间让它与 PowerShell 和 SSH-Sessions 一起工作。也许如果我将来需要更复杂的东西。
