Summary: .ssh/known_hosts does not save port number
Classification: Unclassified
Product: Portable OpenSSH
Version: 5.0p1
Platform: All
OS/Version: Linux
Status: NEW
Severity: minor
Priority: P2
Component: ssh
AssignedTo: unassigned-bugs@mindrot.org
ReportedBy: parasietje@gmail.com
Problem: .ssh/known_hosts does not save the port number, only the
IP/hostname. Thus, multiple ssh-servers on the same IP will cause key
collisions.
Recreate:
Run sshd1 with certificate1 on port 2221
Run sshd2 with certificate2 on port 2222
Connect to localhost, port 2221.
The server certificate is added to .ssh/known_hosts
Connect to localhost, port 2222
Ssh reports REMOTE HOST KEY CHANGED
Expected behavior:
Ssh makes a difference between the ssh-server on port 2221, and the one
on port 2222.
Known workaround:
Use HostKeyAlias to define an alias for the host on port 2221, and for
the host on port 2222.
It would be a lot better if the port number were included in the
.ssh/known_hosts as well.
