Hello, Linux (kernel 3.2) /etc/exports contains the following: /exp -ro,fsid=0,async,subtree_check,all_squash,crossmnt 192.168.1.0/24 /exp/freebsd -ro,no_acl,async,subtree_check,all_squash 192.168.1.0/24 /exp/freebsd/extra -rw,no_acl,async,subtree_check,no_root_squash 192.168.1.0/24 /exp/freebsd/ports -rw,no_acl,async,subtree_check,no_root_squash 192.168.1.0/24 I have also tested it without no_acl, and with the alternative 192.168.1.0/24(options). The used mount command on FreeBSD and the resulting error: # mount_nfs -o nfsv4 192.168.1.3:/freebsd/ports /usr/ports mount_nfs: /usr/ports, : Operation not permitted I am emailing this list and not FreeBSD, because of this next output from tcpdump. Note that 192.168.1.3 is the server and 192.168.1.10 is the client: 17:00:21.761418 IP (tos 0x0, ttl 64, id 62972, offset 0, flags [DF], proto TCP (6), length 116) 192.168.1.3.2049 > 192.168.1.10.1382070341: reply ok 60 getattr ERROR: Operation not permitted The entire output of the tcpdump can be found at the following url: http://sprunge.us/OVbQ Looking forward to resolving this.
