Interestingly, apart from some IPv6 ndp and also showmount problems, this works nicely. Regarding "apart", what does not initially work with this "wrong" setup: - on mizar: "showmount -e " - this is fixed by running "showmount -e mizar" on any of them, then the command on mizar succeeds (if done quickly enough, even while the one on mi= zar is still trying) - Underlying seems to be an IPv6 ndp issue, the showmount is by default usi= ng IPv6 in my setup. See also bug 247912 which is not really valid because of = the "wrong" configuration. So unfortunately I cannot say with which commit this surfaced. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
