Salewski <[email protected]> --- [Just want to note this experience and workaround for other Debian users who might wander through here...] I ran into this on a current Debian machine with the 'openssh-server' package version 1:8.2p1-4. IPv6 is disabled on the host, but via a runtime sysctl.d/ file rather than the kernel command line option. The sysctl config file contains the settings: net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 After cranking-up the sshd debug logging, I would see a ton of messages like the following in /var/log/auth.log when a client would connect with X11 forwarding requested ('-X'): Mar 31 06:22:42 myhostname sshd[3187]: debug2: x11_create_display_inet: bind port 6011: Cannot assign requested address Mar 31 06:22:42 myhostname sshd[3187]: debug3: sock_set_v6only: set socket 9 IPV6_V6ONLY Unlike the documented experience of others (above, and elsewhere on the Net), setting[0] 'AddressFamily inet' *did not* correct the problem for me. However, adding '-4' to the (otherwise empty) sshd startup options via the '/etc/default/ssh' file did work. [0] Actually, it was already set explicitly. -- You are receiving this mail because: You are watching someone on the CC list of the bug.
