💼 Example 9: User Mapping 💼 NFS maps local users to remote users using "usermap" file. 🗺️ Configure in /etc/idmapd.conf: echo "localuser remoteuser" >> /etc/idmapd.conf 🔄 Now, localuser is recognized as remoteuser on NFS share! 🗂️ #NFS #LinuxTricks

🚀 Example 10: NFS Performance 🚀 Boost NFS performance by tuning parameters! For example, increase the read buffer size: sudo sysctl -w sunrpc.tcp_slot_table_entries=128 🔧 Test the settings and adjust for your system! ⚙️ #NFS #LinuxPerformance
