I can't find putty.
dnf install epel-release
Package epel-release-9-4.el9.noarch is already installed.
dnf config-manager --enable powertools
Error: No matching repo to modify: powertools.
Repos appstream, baseos, crb, epel, extras and plus are enabled. Is powertools CRB now?
but anyway, you cannot find it because EPEL didn’t make putty available in their repository. You can use alternatives, such as open a console window and use standard ssh client:
ssh x.x.x.x
where x.x.x.x is the server you want to connect to, or replace it with the hostname.example.com if you are using DNS to resolve.
You can always make a request with EPEL to ask them to add putty rpm to their repository.
