http://bugzilla.opensuse.org/show_bug.cgi?id=1203723 Bug ID: 1203723 Summary: ssh -6 "Address family not supported by protocol" Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Network Assignee: screening-team-bugs@suse.de Reporter: georg.pfuetzenreuter@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Hello, I use `ssh -6 foo` to force SSH connections to use IPv6. This worked fine until I applied the last distribution upgrade to my Tumbleweed system and rebooted. Now ``` $ ssh -6 eros ssh: connect to host eros port : Address family not supported by protocol ``` even though IPv6 connectivity to the host is working fine ``` $ ping -c1 eros PING eros.lysergic.dev(eros.syscid.de (2a03:4000:6:b666::)) 56 data bytes 64 bytes from eros.syscid.de (2a03:4000:6:b666::): icmp_seq=1 ttl=56 time=14.2 ms ``` and a connection without the "-6" flag happens over IPv6 as well (i.e. having it choose v6 automatically instead of forcing it): ``` $ ssh eros $ w georg pts/2 2a02:1748:f7df:9 17:20 1.00s 0.01s 0.00s w ``` Forcing IPv4 with "-4" still works fine: ``` $ ssh -4 eros $ w georg pts/2 185.68.249.200 17:21 0.00s 0.03s 0.00s w ``` Someone in IRC brought the same issue up some days ago: ``` 2022-09-21 13:13:58 nbjoerg is it just me or has the last big ssh update broken AddressFamily pinnin via .ssh/config ``` I attempted the using `AddressFamily inet6` in ssh_config as well and it returned the same result as using the command line "-6" flag.
