Need to so some more research to determine what those "restrictions" are. One thing to try would be to also add CheckHostIP=no CheckHostIP If set to yes (the default), ssh(1) will additionally check the host IP address in the known_hosts file. This allows it to detect if a host key changed due to DNS spoofing and will add addresses of destination hosts to ~/.ssh/known_hosts in the process, regardless of the setting of StrictHostKeyChecking. If the option is set to no, the check will not be executed. -- Right: I dislike the default color scheme Wrong: What idiot picked the default color scheme _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
