>Description: Having >1k mountpoints in fstab, mount -a fails after the 212th mountpoint with the following message: "RPCPROG_MNT: RPC: Authentication error; why = Client credential too weak" All mountpoints are mounted with: rw,soft,noatime,-N,-T,noinet6,-r=8192,-w=8192 Ommitting the -T flag and so using UDP mounts, everything is OK as long as -N is given, otherwise even UDP mounts fail. The Server is FreeBSD-8.0, exporting >1k ZFS mountpoints. In /var/log/messages, there is the following hint "mount request from XXXXX from unprivileged port" As mountd(8) says, one may set vfs.nfsrv.nfs_privport to 0, but could that expose a security risk? >How-To-Repeat: create /etc/fstab with a large number of NFS mounts $ mount -a >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
