OpenSSH server: Other version running than installed
I have an Ubuntu 18.04 server. I installed openssh-server and openssh-client. According to apt, the installed version of both packages is 7.6p1-4ubuntu0.1, but the running version of the ssh-server (sshd) is OpenSSH_6.7p2 Ubuntu-4p1. The version of the client (ssh) is correct.
I already restarted the server several times, but the running version is still the same.
Recently I reinstalled OpenSSH, because my clients couldn't connect to the server with version 6.7. See: SSH connection closed right after login
It worked for a while, but after some system-updates, it switched back to version 6.7. (the installed package is still 7.6)
Could anybody please help me with this? I don't understand how the running version can differ from the package version.

How did you determine that versionOpenSSH_6.7p2 Ubuntu-4p1is running? What is the output ofdpkg -l | grep openssh? Add both to your question by editing your question.

@Thomas I executedsshd -V(and/usr/sbin/sshd -Vwhich resulted in the same output). Additionally, my client on OS X tells me that the server is usingOpenSSH_6.7p2. The output of your command is a table with openssh-client, -server and -sftp-server. The version is1:7.6p1-4ubuntu0.1for all of them.

@guiverc: not necessarily, but if you have such a big difference in versions, then something is wrong.

@FelixSFD: sosshd -Vdoes result inOpenSSH_6.7p2? Did you somehow overwrite the binaries in/usr/sbin/sshdby copying things or similar?

@FelixSFD: so
sshd -V does result in OpenSSH_6.7p2? Did you somehow overwrite the binaries in /usr/sbin/sshd by copying things or similar?– Thomas
