I have a redhat server 7.5. I have a openssh installed on this server. The openssh is 7.4. I need to upgrade openssh 7.4 to 7.6 AS Nessus, vulnerability scanner scanned this vulnerability (Openssh <7.6) and thus need to upgrade to 7.6 or later.The details is found here, https://www.tenable.com/plugins/nessus/103781.
I found the link, https://ftp.openbsd.org/pub/OpenBSD/OpenSSH/openssh-7.6.tar.gz but they said that this cannot be installed on Red Hat as you cant install bsd on Linux. I referred to this link, https://superuser.com/questions/577389/make-command-for-installing-openssh-on-ubuntu/
Thus I went to this link, http://www.openssh.com/portable.html to have a portable version. I used this link, https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-7.6p1.tar.gz.
I downloaded this file in /tmp directory.
I performed the following command,
# tar xvfz …/openssh-7.6p1.tar.gz # cd ssh # make obj ←-------------------- error message # make cleandir # make depend # make # make install
I got this error when I performed the command make obj. The error is
make: *** No rule to make target 'obj'. Stop.
