[Bug 1592] New: Fingerprints for SSHD host key don't match (local ssh-keygen -l vs. ssh localhost)
...--> (http://bugzilla.mindrot.org/attachment.cgi?id=1628)
All files needed to set up test case
Problem:
I've come across two host key pairs which do not work correctly:
- ssh-keygen -l -f key_A gives fingerprint fp_A
- ssh'ing to an sshd using key_A as host key givs fingerprint fp_B
- fp_B != fp_A (actually the ssh client receives a different host
key)
The problem occurs with OpenSSH 5.1p (both openSUSE 11.1 and Knoppix
6.1 (Debian based)) and OpenSSH 4.6p1 (openSUSE 10.3).
It's not an MITM. I could reproduce the behavior booting from a clean
live Linux CD, ssh'ing...
