Hi,
if you already have ssh public keys in
/etc/ssh/ssh_host_*.pub, you can do
# ipa host-mod --updatedns --sshpubkey "*ssh-rsa
AAAAB3NzaC...*" client.ipa.test
(where the bold text is the content of your .pub file).
Then in order to check what was done:
# ipa dnsrecord-show ipa.test client
Record name: client
A record: 10.0.147.130
SSHFP record: 1 1
2D9747370DF5CEDDE66AC4DC354076326F466A0A, 1 2
0B1FB068265381BE51CEA14D315C3A2647E98BC9672B0640045C9D5131BA404C
You can check that they correspond using
# ssh-keygen -r client.ipa.test -f
/etc/ssh/ssh_host_rsa_key.pub
client.ipa.test IN SSHFP 1 1
2d9747370df5cedde66ac4dc354076326f466a0a
client.ipa.test IN SSHFP 1 2
0b1fb068265381be51cea14d315c3a2647e98bc9672b0640045c9d5131ba404c
The fingerprints are also visible using
# ipa host-show client.ipa.test
...
SSH public key fingerprint: SHA256:Cx...
and can be checked using
# ssh-keygen -l -f /etc/ssh/ssh_host_rsa_key.pub
3072 SHA256:Cx...
Does it help?

Hi guys.
What is the correct way to update/modify server's
sshfp records?
I assumed those are in: /etc/ssh/ssh_host_*.pub
and I should use 'host-mod --updatedns ..'
but then such records do not look like what IPA
had/created.
many thanks, L
_______________________________________________
I've probably phrased poorly what I wanted to say.
I did that, as I said I did: 'host-mod --updatedns ..' and...
just after this I did: 'ipa host-show'
which showed also "ssh public key (FP separately as usually)
records" which puzzled me a bit as, those where not there
for/from "regular" client/replica install (including this
host prior to manual update), but...!
now those "ssh public key" records 'ipa host-show' does not
show anymore... now I begin to worry, or.. it's how IPA
"behaves"?
ps. Flo, do the right thing, follow etiquette/lang rules.
I'd like to think it's not just conversation between us two.
How do you like to read your book? aha! exactly.
many thanks, L.
