Openssh

OpenSSH is a 100% complete SSH protocol 2.0 implementation and includes sftp client and server support. OpenSSH also includes transitional support for the legacy SSH 1.3 and 1.5 protocols that may be enabled at compile-time. UPDATE -We have updated ssh-shellhost.exe binary (fix for #1222) in V7.7.2.0 payload on 8/4/2018. This release includes. Support for auto updating knownhosts via ssh and ssh-keygen; Optimized group membership resolution that results in vast performance improvement in processing simple user/group configuration rules. I have a Red Hat Enterprise Linux server (7.5 x8664). I have OpenSSH version 7.4. I was asked to upgrade it to a later version for security reasons: Nessus states that OpenSSH should be ugraded from 7.4 to 7.6 or later.However the Red Hat software and downloads does not have the latest package RPM. To upgrade openssh from 7.6 to 8.0 on Ubuntu 18.04 (bionic), I followed the instructions given here: How to Install OpenSSH 8.0 Server from Source in Linux. The version I started with: $ ssh -V OpenSSH7.6p1 Ubuntu-4ubuntu0.3, OpenSSL 1.0.2n 7 Dec 2017 Here are the commands to upgrade.
