[Bug 1602] ssh: doesn't handle IPv6 addresses with brackets
https://bugzilla.mindrot.org/show_bug.cgi?id=1602 --- Comment #8 from Marc Herbert <marc.herbert+mindrot at gmail.com> --- Fun fact: ssh _does_ produce brackets for IPv6 addresses in .ssh/known_hosts: [review.openstack.org]:29418,[104.130.246.32]:29418 ssh-rsa AAAAB3NzaC1yc2... [review.openstack.org]:29418,[2001:4800:7819:103:be76:4eff:fe04:9229]:29418 ssh-rsa AAAAB3Nza... But it can't parse back what it printed itself: ssh ssh://[review.openstack.org]:29418 OK ssh ssh://[104.130.246.32]:29418 OK ssh ssh://[2001:4800:7819:103:be76:4eff:fe04:9229]:29418 FAIL with usage message OpenSSH_8.2p1, OpenSSL 1.1.1g 21 Apr 2020 Digression: with many operating systems using randomized IPv6 addresses by default for privacy reasons, using ssh to .local systems on the same LAN causes uncontrollable .ssh/know_hosts growth. -- You are receiving this mail because: You are watching the assignee of the bug.
