Screen shot # 2 - error message

I am a retired dude so this is a personal use case.

I have a laptop running Artix with cinnamon desktop environment, and a desktop PC running Manjaro using the suckless dwm window manager as my daily drivers.  On both of these, I prefer NEMO as the file explorer.

I also have a FreeBSD box that is my home file server.

Both of the linux machines have been stable for several months, and on each I have had a shortcut established in Nemo to my home directory on the FreeBSD box.  That has given me no problem heretofore.

Recently, arch has pushed down the openssh 8.5 package.  I found that the upgrade breaks my shortcut to the FreeBSD box on both my linux machines.

Work arounds are to just use command line sftp to move files or map the FreeBSD to local file system in linux via sshfs mounting.

As soon as I realized the 8.5 package update was the breaking change, I blacklisted package manager for openssh and rolled back to 8.4 and the problem completely went away. 



Here are symptoms / circumstances

* I have static LAN IP addresses assigned to all 3 machines mentioned above on my router per MAC address, and I built my shortcuts per x.x.x.x addresses, not machine names.

* On either machine, attempt to open the link to my FreeBSD in Nemo ("Connect to server...")

  - Message "Connecting..." displays in top of dialog box with spinning circle for 40 seconds  [shot1.png]

  - After 40 seconds elapsed, error "Timed out when logging in" displays and connection fails. [shot22.png]
  
  - On the server side  (log text below)


* On the laptop with Artix I could still open my home drive on the Manjaro desktop using the same steps that failed to open the FreeBSD as described.

* I could still use plain-vanilla 'ssh' at the command line without any problem.

* I could still use SSHFS mounting without any problem.

This means that OpenSSH as supplied (and modified by Arch) still works, so it's likely a problem with something other than OpenSSH.  There's not much we can do to diagnose this, so you need to report this to Arch.

Closing as there is no evidence of this being something that can be reproduced with the stock OpenSSH as supplied by the OpenSSH team.  Please reopen if you can reproduce this with the stock OpenSSH.

closing bugs resolved before openssh-8.9
