Note: netstat does not show state for UDP ports, so a missing "LISTEN" is n= ot perceived as a bug. Steps to repeat: NFS shares enabled in /etc/rc.conf, and /etc/exports or with ZFS exports as= per the handbook: https://www.freebsd.org/doc/handbook/network-nfs.html # service nfsd start # service mountd reload $ sockstat -l4p 2049 $ netstat -4na # pkg install sysutils/lsof $ lsof -i TCP:2049 $ lsof -i UDP:2049 Potentially relevant notes from manpage: -a Specifies that nfsd should bind to the wildcard IP address. T= his is the default if no -h options are given. It may also be specified in addition to any -h options given. Note that NFS/= UDP does not operate properly when bound to the wildcard IP address whether you use -a or do not use -h. --=20 You are receiving this mail because: You are the assignee for the bug.=
