Broken pipe when connecting from ubuntu 14.04

[derhoeppi]

Hi,
i'm troubleshooting my brocade ssh Connection. Therefore i used an ubuntu 14.04 (default Installation). If i connect from ubuntu to my Windows openssh server i get the message: Write failed: Broken pipe

What's the Problem?

Hello I do the the same issue.

I installed the Win32-OpenSSH via chocolatey (choco install -y win32-openssh --params='/SSHServerFeature /KeyBasedAuthenticationFeature') and I'm getting the same issue:

If I stop sshd service and start sshd -d or just sshd via command line - it works fine...

[MattHodge]

+1 Same problem as @ruzickap

[MattHodge]

Looks like a bug with the Chocolatey installation. Doing ntrights.exe -u +r SeAssignPrimaryTokenPrivilege from inside C:\Program Files\OpenSSH-Win64 fixes it.

[DarwinJS]

@MattHodge - are you installing the fixed version? => 2016.05.30.20160807

[ruzickap]

Runniong ntrights.exe -u "NT SERVICE\SSHD" +r SeAssignPrimaryTokenPrivilege inside C:\Program Files\OpenSSH-Win64 fixes it.

I'm using the latest available version, but I still need to run the command mentioned above to make it working:

C:\Users\vagrant>choco list --local-only
Chocolatey v0.10.0
chocolatey 0.10.0
win32-openssh 2016.05.30.20160807
2 packages installed.�

Thank you

[SteveL-MSFT]

I would suggest following up with the Chocolatey package owner https://chocolatey.org/packages/win32-openssh

[DarwinJS]

This should be working now in the latest release (still in moderation). You can try it with:

choco install -y win32-openssh -version 2016.05.30.20160902 -params='"/SSHServerFeature"'

[ruzickap]

Thank you.
It's working fine with the latest version 2016.05.30.20160902.
