Valentin and me are now playing quite a lot with copr-*-dev as part of new OpenStack testing and I always have to ask somebody to wipe the entry from known_hosts on lockbox otherwise rbac will refuse to connect. Can I suggest to put into ssh_config on lockbox: Host copr-be-dev.cloud.fedoraproject.org copr-fe-dev.cloud.fedoraproject.org UserKnownHostsFile /dev/null Can I get two +1? And can somebody put it there then? -- Miroslav Suchy, RHCE, RHCDS Red Hat, Senior Software Engineer, #brno, #devexp, #fedora-buildsys
