Client is version 6.1.3, server is 6.1.6

ivan-tkatchev avatar Mar 29 '21 19:03 ivan-tkatchev

There were some mutex fixes. Can you try 6.1.7 for both client and server?

MisterTea avatar Apr 07 '21 17:04 MisterTea

I'm seeing the same in 6.1.7 installed today from the Ubuntu PPA.

When the client public key is not on the server, the client shows the ssh password prompt after the UnixSocketHandler.cpp:167 line. At this point, the server is dead. Whether the public key is on the server or not, the client shuts down after that line because it can't talk to the server anymore.

I'm seeing the same in 6.1.7 installed today from the Ubuntu PPA.

I'm also seeing this same crash on Clear Linux building from source on 6.1.7 both client and server

mcybz avatar May 23 '21 21:05 mcybz

Seeing same issue on 6.1.8. Any ideas?

mcybz avatar Jun 30 '21 12:06 mcybz

This looks like an issue with libsodium. Let me see if I can repro

MisterTea avatar Aug 26 '21 17:08 MisterTea

@mcybz I think this is some backwards-incompatibility in libsodium. Can you check if, on the server, you can "et localhost"?

MisterTea avatar Nov 03 '21 17:11 MisterTea

@MisterTea thanks for picking this up.

So yeah et localhost core dumps for me.

Happy to try something else?

mcybz avatar Nov 05 '21 17:11 mcybz

Not sure if relevant, but I should mention as Clear Linux doesn't have an ET bundle (package), I'm compiling from source as per the readme instructions.

mcybz avatar Nov 05 '21 18:11 mcybz

Sorry for the multiple posts. Wanted to try rebuild and this time I get a different result on 6.1.9.

Upon start it pauses for 2 seconds then quits with the above messae. Not sure if this is the expected result.
