NFS connections from unprivileged ports

Hello hv036,

By default, Dell's OneFS NFS server accepts connections only from privileged ports (TCP/IP ports 1023 and lower). To allow NFS mounts from unprivileged ports (1024 and higher), you need to configure OneFS.

Configuration Steps:

1.       Modify Global Configuration:

isi_gconfig registry.Services.lwio.Parameters.Drivers.nfs.NFSPrivPort=0

By default, registry.Services.lwio.Parameters.Drivers.nfs.NFSPrivPort is set to 1, which disallows unprivileged ports.

2.       Restart NFS Service: After changing the configuration, restart the NFS service on all nodes in the cluster:

isi_for_array 'pkill nfs'

3.       Verification: To verify the configuration, clients can mount with the noresvport option:

mount -t nfs -o vers=3,noresvport xxx.xxx.xxx.xxx:/ifs/data/testdir /mnt

Use netstat to check the connection:

netstat -an | grep 2049
