I keep getting these errors showing up in the log from sshd: error: kex_exchange_identification: banner line contains invalid characters I finally tracked them down and understand the nonsense that is happening: For historical reasons (having to do with butthead IT people at work deciding outgoing sshd should be blocked by firewall), I listen on the https port (443) as well as the normal 22 on my sshd at home. Apparently "helpful" web browsers on my android devices and wot-not decide they ought to probe connections to see if https is possible before falling back to http, so they all probe my ssh daemon :-). The error has been happening forever, but the latest sshd now logs it (it previously just ignored it). _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
