sshd Connection closed by <IP> [preauth]
by mfoley from LinuxQuestions.org on (#6GY4Z)
I'm stumped. I have a Linux host, DC1, which was located remotely. I was able to ssh into it from my home linux computer QUADMON without problem. I then brought this host home and connected it to my LAN with IP 192.168.0.2. But now when I try to connect from QUADMON I get the following in DC1's /var/log/messages:
Code:sshd Connection closed by 192.168.0.17 port 54786 [preauth]If I try connecting from another linux computer on my home LAN I get:
Code:ssh_exchange_identification: read: Connection reset by peersshd is listening on 22 on DC1. DC1 has an empty /home/mfoley/.ssh/know_hosts.
I can telnet from QUADMON to port 22 on DC1.
Any idea why I can't ssh from QUADMON to DC1?
