![]() Thanks to for helping to figure this out with me in slack. If you encounter this problem, upgrade your device firmware if possible, or complain to the vendor that their devices are running an out of date SSH server. Due to a non-RFC-compliant check of the available authentication methods in the client-side SSH code, it is. SFTP / SCP file transfers and remote terminal connections are popular use cases for an SSH server. ![]() Remark: You can swap or change your SSH server at any time using DietPi-Software. An SSH server is a software program which uses the secure shell protocol to accept connections from remote computers. Sign_and_send_pubkey: signing failed for RSA "" from agent: agent refused operationÄ¡Password's logs show this error: Error handling sign request: Key(expected RSA signature algorithm, but found a Ed25519 one) Free SSH Tunnel Server - With Renewable Technology That Supports Multiple Connections Such As: Dropbear, Openssh, Stunnel SSL, Multi Port SSLH, Squid Proxy. An issue was discovered in Dropbear through 2020.81. Dropbear is a lightweight SSH server, installed by default on DietPi systems. The ssh logs when this occurs will look something like this: $ ssh -vvv 10.0.1.10Äebug3: sign_and_send_pubkey: signing using ssh-rsa SHA256: So OpenSSH has steadily been dropping support for older protocols that Dropbear used in the past. If you have this, this may be a problem for you depending on when you most recently updated the firmware. Routers with OpenWRT firmware installed on them also run Dropbear. Dropbear is the most stable SSH client/server for Termux. OpenSSH offers a little more in options (sftp for example). As for speed and security, they're pretty much on par. Find it's a common SSH server on routers. Support for these signature algorithms were added in version 2020.79. dropbear is mainly aimed for smaller footprint (embedded devices). That version of Dropbear only supports ssh-rsa signatures and not rsa-sha2-256 or rsa-sha2-512. If you are on the server, look at the process attached to the network port where ssh is expected ( 22 or something else). are compiled with the DEBUGTRACE option and then run using the -v switch. If you also have trouble logging into a device running Dropbear, check the version: # ssh -V According to its self-reported version in its banner, Dropbear SSH running on. I'm just posting this here for anyone else who may encounter this issue trying to log into a similar device. ![]() This is an alternative SSH implementation that's commonly used on low power devices like routers and access points. They said to use the command ssh -v, and while that gives a lot of information, I cant see any Dropbear stuff listed. ![]() After a lot of investigation in a thread on slack over the past 2 days, I discovered that 1Password's ssh-agent doesn't support logging into UniFi Access Points, which are running an old version of Dropbear SSH. ![]()
