How to use the latest version of openssl？thx :)

Thanks very much! You saved my life. Old ssh stopped working after upgrading to openssl-1.1.1

Something has changed :) All CentOS and epel repos for CentOS 6 are dead :)

Before installation you have to replace:

• CentOS-Base.repo with Vault (just google it)
• epel.repo with any mirror (i've used princeton mirror)

Before rpmbuild command you should fix bad permissions (owner\group), my os doesn't have user with uid 1000:

chown -R user:group rpmbuild

Also you should update repos section in /etc/mock/epel-6-x86_64.cfg, just copy content of CentOS-Base.repo and epel.repo files.
Be careful about file format, it ends with triple quotes """.

this solves bulding the rpm's:
openssh-9.1p1-2.el6.src.rpm
openssh-9.1p1-2.el6.x86_64.rpm
openssh-clients-9.1p1-2.el6.x86_64.rpm
openssh-debuginfo-9.1p1-2.el6.x86_64.rpm
openssh-server-9.1p1-2.el6.x86_64.rpm
.
without such a lot of issues like the very old script here on this side
