<tt>Regarding SSH connection, an issue has been created in openbmc and I also see others having this same issue.</tt><br>
<tt>From the comments, I have run "dropbear -E -p 5022" in the target (UART-console) and tried to connect the target using "ssh -p 5022 <ip>" and ssh connection established.</tt><br>
<tt>But, reboot and systemctl commands hangs.</tt><br>

<tt>Hi George,</tt><br>
<br>
<tt>We are facing connection issue in accessing the target after flashing the latest image.</tt><br>
<tt>In openbmc-test-automation, whether any test cases are present in CI to identify these issues ?</tt><br>
<tt>Please let us know your comments on this.</tt><br>

<tt>After analysing the latest commits, reverted the below commit in the latest build and checked by flashing the image. Now the target is connecting through SSH. Please help us on fixing this issue.</tt><br>

<tt>Hello Patrick,</tt><br>
<br>
<tt>I saw the post about dropbear, but that commit was updated on July16 and my target is connecting till August last week image. I don't think that will be an issue. Also on working image, I tried with 'ssh -vvv ' and I got below information.</tt><br>

<tt>Subject: Re: Connection issue in OpenBMC image</tt><br>
<br>
<tt>Hello Jayashree,</tt><br>
<br>
<tt>I saw an output `ssh -v` from you earlier, but there really wasn't any useful information there. It looked like the connection was being made and keys were exchanged and then the log just stopped abruptly. This tells me it likely isn't a networking issue
but an issue in the handshake between the ssh-client (your computer) and ssh-server (dropbear). You can continue to add '-v' parameters up to `ssh -vvv` and you'll get increasingly more information.</tt><br>
<br>
<tt>Joseph Reynolds recently posted a reminder about dropbear disabling weak ciphers[1]. Is it possible that your client is using an old cipher?</tt><br>

<tt>This is the log that also looks like a good connection. Identity files were attempted to be exchanged. Version strings were exchanged. And then the log just abruptly stops. Was the connection dropped? Is it hung?</tt><br>
