(There are many variants of the mount utilities and patch versions RM> of the nfs4 client for Linux, so your mileage definitely may vary.) I'm using Sabayon 3.5 with kernel 2.6.25 here. I guess I could try and update to the new Sabayon 5 for testing (if that might help). The installed nfs packages are: net-libs/libnfsidmap-0.20 net-fs/nfs4-acl-tools-0.3.2 net-fs/nfs-utils-1.1.2 RM> I'll be happy to look at a tcpdump capture, if you get one, rick You should have received it by now. I'm looking forward to your answer. Thanks again. cu Gerrit
