Description
I am trying to connect via SSH to a remote Windows machine running a bitvise SSH server (process named "BvSshServer"). The extension fails to connect with the following error:
[08:32:35.376] > gps : Cannot find a process with the process identifier 1292.

[08:32:35.465] > no sshd parent proc
Open for full log with some redactions.

[08:32:36.814] ------
The error occurs in the MS-defined function a_ as it seeks to find the SSH daemon PID by finding a parent process named sshd. When using bitvise's SSH server, there is no sshd process. Rather, the parent process during an SSH connection using bitvise are:
>powershell .\list_parent_procs.ps1
cmd
toterms
BvSshServer
services
wininit
Open for content of `.\list_parent_proces.ps1` .
function a_ {
# get parent processes
$t_ = $PID
while ($True){
$u_=(gcim win32_process | ? processid -eq $t_).ParentProcessId
if (!$u_) {
exit 0
}
$n_=(gps -Id $u_).Name
"$n_"
if ("$n_" -eq "wininit") {
exit 0
}
$t_ = $u_
}
}
a_
How can I connect to an SSH daemon not named sshd?
