similar to: Feature Request: Invalid sshd port fallback

I see your point and that makes valid sense;I even change default port. "It would be better to let you know the port is wrong and fail to start until you fixed the problem and selected a valid non-standard port." Is there any reason something like this isn't implemented already? Could it be implemented? On Thu, Jul 30, 2015 at 2:02 PM Ron Frederick <ronf at timeheart.net>

I could not find anything in the mailing list archive or bug tracker. In ssh2.h, the value (4) is re-used 148 #define SSH2_DISCONNECT_KEY_EXCHANGE_FAILED 3 149 #define SSH2_DISCONNECT_HOST_AUTHENTICATION_FAILED 4 150 #define SSH2_DISCONNECT_RESERVED 4 151 #define SSH2_DISCONNECT_MAC_ERROR 5 Is this intentional? Thanks, Noah Zalev

Thanks for clarification. One question though: As far as I have tested openssh, it logs every unsuccessful authentication attempt on the very moment it becomes unsuccessful, not after the connection is closed (after timeout or when reaching max auth attempts). Is this true or not even for this attack or not? Because if it is true, if there is a IDS system that bans IP after X failed logins,

Greetings everyone! I would like to know if adding support for Unix socket to sshd would be a feature that would be consider to be added upstream? (ListenAddress). One of the main reason for this question to you all is that tor now has Unix socket support for hidden services that is traffic of a hidden service can be forwarded to a Unix socket (see HiddenServicePort in tor.1). The rationale

I?m working on an implementation of ?gssapi-with-mic? authentication for my AsyncSSH package and trying to get it to interoperate with OpenSSH. I?ve gotten it working, but there seems to be a discrepancy between the OpenSSH implementation and RFC 4462. Specifically, RFC 4462 says the following in section 3.4: Since the user authentication process by its nature authenticates only the client,

Hello, In testing security key support in OpenSSH 8.2, I had some trouble making the ?no-touch-required? option in the authorized_keys file work in conjunction with OpenSSH certificates. I think I?ve figured it out, but I think there may be a bug in ssh-keygen related to this. To make ?no-touch-required? work with certificates, I actually had to do three things: Generate the security key with

Hello, I?m trying out the ?resident key? functionality in OpenSSH 8.2, and I?m having trouble getting it to find keys that I?ve created. I?m trying to create a new resident key using: ssh-keygen -O resident -t ed25519-sk -f <filename> This creates a key, but I?m not actually sure it is creating a ?resident? key, as when I try to dump out the resident keys with either ?ssh-keygen -K?

I updated to the latest versions of libfido2 and openssh-portable tonight, with an intention to test out the security key functionality and look closely at the changes over the last couple of months to see if I need to change anything in my AsyncSSH implementation to stay in sync. However, it seems that libfido2 no longer provides the ?libsk-libfido2.so? library that it used to. That was something

There is no hash algorithm associated with SSH keys. The key format for RSA keys is always ?ssh-rsa?, and it is capable of being used with any of the available signature algorithms (ssh-rsa for SHA-1 and rsa-sha2-256 or rsa-sha2-512 for SHA-2). See section 3 in https://www.rfc-editor.org/rfc/rfc8332: rsa-sha2-256 RECOMMENDED sign Raw RSA key rsa-sha2-512 OPTIONAL

Hello, I noticed a problem recently when running some test code against the OpenSSH 7.6p1 ssh-agent. These tests ran fine against OpenSSH 7.5p1 and earlier, but with OpenSSH 7.6p1, they were suddenly causing ssh-agent to exit. The request being made was a ?sign? request, and the point of the test was to have the sign operation fail. To trigger this, I was passing in an invalid key blob
