Package: openssh-client
Version: 1:7.4p1-5
Severity: normal
Dear Maintainer,
After having manually added a host to my known_hosts file, I wanted to
hash the new hostname. According to ssh-keygen(1),
-H ... This option will not modify existing hashed hostnames and is
therefore safe to use on files that mix hashed and non-hashed names.
So, I used `ssh-keygen -H` and was notified that all hostnames have been
hashed.
However, when I subsequently tried to access an old server (not the
newly added one), ssh asked me to verify its fingerprint. I compared the
new known_hosts file with the automatic backup and noticed that the
hashes of all 500+ entries in my known_hosts file had changed, so not
only -- as expected -- the single new one.
Workaround: put line in extra file, hash the hostname using `ssh-keygen
-H -f <file>` and append it to the actual known_hosts file afterwards.
Thank you!
Best,
Maximilian
