Potential SSH2 exploit
I just noticed (at least on OpenSSH 3.0p1) that even though I have both RSA
and DSA keys available in sshd_config on a server, only a ssh-rsa line
shows up in known_hosts on the client side, not a ssh-dss line (that
priority may come from the fact that my RSA key is listed before my DSA key
in sshd_config). If I comment out the RSA key in sshd_config and restart
the server, then the next time the

Out of interest, did you, perchance, try running an ssh-keygen -l on a
DSA-infested file?

Manual Page for ssh_config
Hello,
I am using OpenSSH on a FreeBSD box
(OpenSSH_3.5p1 FreeBSD-20030201, SSH protocols 1.5/2.0, OpenSSL 0x0090701f)
and I noticed that the manual page for ssh_config probably needs to be
fixed. The manual page says that the default value for the parameter
HostKeyAlgorithms is "ssh-rsa,ssh-dss" but that seems to be wrong,
because ssh only uses RSA-Keys in my .ssh/known_hosts if I

Possible problem with hostbased protocol 1 rhosts authentication
I found this problem when working with the Suse9.1 distribution, but have
since reproduced it with a vanilla build of Openssh
(openssh-3.9p1.tar.gz). Basically I cannot get a command like this:
XXXX>ssh -vvv -1 -o "RhostsAuthentication yes" AAAA
to work. Yes the appropriate settings are in the servers sshd_config file.
Hostbased protocol 1 ssh using rhosts between computers is

known_hosts question for Ubuntu Server 14.04 and 16.04 LTS
Hello & thanks for reading.
I'm having a problem configuring known_hosts from scripts so an accept
key yes/no prompt doesn't appear.
I'm using this command to detect if the server is known and add it to
known_hosts:
if ! ssh-keygen -F ${IP_ADDR} -f ~/.ssh/known_hosts > /dev/null 2>&1; t
hen ssh-keyscan -p ${PORT} ${IP_ADDR} >> ~/.ssh/known_hosts; fi

shared private key
Hi SSH-devs,
This may be a bit off topic for this list, but....
Would it be ok to share a private key in an installer script so long
as the corresponding public key is setup like this...
command="cat ~/.ssh/id_rsa.pub" ssh-rsa AAAA...
I'm looking for a secure way to get a user to share their public key
through SSH which can be invoked from an installer on another
host...for

Where to look next?
Thanks for your suggestion! It seems to have gone a little further this time, but isn't accepting the key and is failing back on password-based auth.
We're double-checking that the public key was correctly configured with the account, and also trying a DSA key to see if it behaves differently.
Is there anything you'd suggest we look at or try at this point, and thank you very much

Disconnecting: protocol error: rcvd type 98
When I SSH using protocol 1 from a Debian box running OpenSSH 2.9p2-4
to a sparc.sunos5 box running vanilla OpenSSH 2.9.1, after a little
while (of inactivity?) I get the following message on the client
terminal:
Disconnecting: protocol error: rcvd type 98
Looking further, this message is actually caused by the SSH daemon.
However, I'm at a loss to determine why sshd is doing this.

DSA Fingerprints...
Hello,
Questions, observations, and curiosities.
Maybe this is something stupid or maybe I'm doing something wrong...
But... In light of the Kurt Seifried paper on SSH and SSL, I was looking
for the finger prints on my various servers and known hosts files to have
a little crib sheet and maybe plug the list into a database on my palm pilot.
I found that ssh-keygen lists out the

Keysize mismatch error on host key
I've got a problem that I'm hoping the list can help with, otherwise ...
Heres the problem, I've got OpenSSH 1.2.2p1 running on my Intel Linux
box as the secure server. I can connect from another Intel Linux box
using scp and it all seems to work fine.
Another box tries to connect and it gets a warning about the host
keysize not matching. I'm thinking this could be some byte

HashKnownHosts vs @cert-authority
Hi folks,
maybe I am too blind to see, but would it be possible to
avoid extra entries in known_hosts, if the remote host
has a signed public key matching a @cert-authority line?
Something like
Host *
HashKnownHosts unsigned
This could help to keep the known_hosts file small and
yet get all the unsigned public keys in.
Just a suggestion, of course. Regards
Harri

Not sure whether anything should be done with it, but I noticed so
thought I'd mention: if you pass ssh-keygen -R a known_hosts file with
DSA sigs, you get "invalid line" warnings.

hostbase authentication of hostcertificate

I am trying to use the hostcertificate to do the hostbaed authentication with the steps in the regress/cert-hostkey.sh
