Summary | 0005095: SSH over NAT fails with broken pipe message | ||||
Description | For all versions after OpenSSH_7.7p1, when using a NAT connection, any attempts to connect over SSH fail with an error message 'Broken pipe' | ||||
It's hard to tell with a description this brief, but this is almost certainly related to a known VMware bug[1]. If the reporter could confirm that this was observed in a VMware VM with NAT, that would be very helpful. That said, I was able to successfully reproduce the issue with those assumptions. In short, as of OpenSSH 7.8 the default IPQoS values have changed to DSCP AF21 for interactive traffic and CS1 for bulk traffic[2][3]. vmnat does not support these, and breaks the connection immediately after ssh auth completes. As far as I can tell, there are four possible solutions: 1) Wait for VMware to fix vmnat (no sign of this happening in sight, this bug has been present for months) [1] - https://communities.vmware.com/thread/590825 |

This was using vmWare Fusion 8.5.10 on a Mac with a Kali VM with a NAT connection. I can confirm that using "IPQoS=throughput" on the command line when using SSH works. Thanks |

Due to the age of the OS (Kali Moto [v1], Kali Safi [v2], Kali Rolling <= 2018.4), these legacy versions are no longer supported. Please could you see if you are able to replicate this issue with the latest version of Kali Linux - https://www.kali.org/downloads/)? If you are still facing the same problem, feel free to re-open the ticket. If you choose to do this, could you provide more information to the issue you are facing, and also give information about your setup? |
