Whatever 6.1-RELEASE comes standard with. After your mail I did cd /usr/ports ; echo */*nfs* net-mgmt/nfsen net/nfsshell net/pcnfsd net/unfs3 /usr/ports/net/unfs3 offers a non ernel V3 server but I'd still need a v3 client I suppose ? Are 6.2-pre or current using V3 NFS then ? Hints which way to jump / where to RTFM please :-) -- Julian Stacey. BSD Unix C Net Consultancy, Munich/Muenchen http://berklix.com Mail Ascii, not HTML.
