Hi all, I just spin off two CentOS6 VMs to replicate a problem I had on Friday afternoon at work. I want use NFSv4 to share folders. Short, from memory, I have on the server: - /etc/exports populated - domainname configured - domain in /etc/idmapd.conf - rcpidmapd running On the client, I have - /etc/fstab entries with nfsvers=4 - SecureNFS=no in /etc/sysconfig/nfs - domainname configured - domain in /etc/idmapd.conf - rcpidmapd running When I mount, it works, but all files belong to nobody.. What do I miss? If I start rpcimapd in verbose, it complains about /proc/net/nfsv4/nfstoid or something similar missing(sorry, I am not there yet with my replicas) but I am not sure whether this matters. DuckDuckGo and Google did not help much yesterday. I do not have Kerberos or LDAP configured, the firewall (2049 connection only) restricts me and I 'don't mind' that the two machines trust each other. The environment is quite isolated and under tight control. Thanks for ideas Peter
