 |
|
I had my oldest and slowest machine lock up during updates, so I had to reboot it. It is a 32 bit celeron. After the reboot, I can no longer ssh into it:
| Code: |
moses ~ # ssh root@jacob
ssh_exchange_identification: read: Connection reset by peer
moses ~ #
|
I googled the message, but the answers were all over the place. This machine is a firewall/router and has been up for about a year before the reboot this morning. I checked the /etc/ssh/sshd_config file for any undesired changes, but it looked ok at first glance.
Anybody know what's causing this?

You are trying to ssh to an old box that has old cyphers from a new machine that has those cyphers disabled
You need to enable them in your ssh client config, either globally in /etc/ssh/ssh_config or in your local .ssh/config

No, it was much simpler than that. When I rebooted that machine after the lock-up, I rebooted its hot standby by mistake. So I never rebooted the hung machine.
