Unable to add proxy via PowerShell, SSHKEYCONVERTER.EXE executable not found

[mkevenaar]

Case#: 07784904

We are working on adding proxy servers via PowerShell and we are unable to do so because it failed with the message:

Code: Select all

Add-VBOProxy: SSHKEYCONVERTER.EXE executable not found.

PowerShell script:

Code: Select all

$hostname = "my.host.name"
$keypasswd = Read-Host "Supply SSH Key Password" -AsSecureString
$credentials = New-VBOLinuxCredential -Account "my_svc_account" -ElevateAccountToRoot:$true -PrivateKeyFilePath "C:\Path\To\id_ed25519" -Passphrase $keypasswd
$proxy = Add-VBOProxy -Hostname $hostname -Port 22 -LinuxCredential $credentials -force

We are running the latest version of VB365: v8.1.2.180 P20250619

Has anyone been able to do this with an SSH key using PowerShell?

Hi Maurice,

Thank you for opening the case. I tested it myself and encountered the same error in my lab. After checking internally, I couldn't find any known issues related to this.

For now, I recommend continuing with the case. I'll also inform our internal VB365 team about the case.



Best,
Fabian

Hi Fabian,
