## To disable CIFS Null Sessions (no data mover reboot is required)
[nasadmin@nyvnxcs0 ~]$ server_param server_2 -f cifs -modify nullSessionNotOnFS -value 0
server_2 : done
## To check current parameter value
[nasadmin@nyvnxcs0 ~]$ server_param server_2 -f cifs -info nullSession
server_2 :
name = nullSession
facility_name = cifs
default_value = 1
current_value = 0
configured_value = 0
user_action = none
change_effective = immediate
range = (0,1)
description = Allows Null Session connection to share
The parameter cifs.nullSession allows client to use Null Session (no username, no password) to connect to a share.
By default, user will be able to login, but not read/write on the File System. The mapped UID for such user is -2 value.
param cifs nullSession=0 prevents clients from connecting to a share when using Null Session.
param cifs nullSession=1 allows clients to connect to a share without username and password.
Please also refer to cifs.nullSessionNotOnFS parameter.
