I was asked to open ssh and run this commands to enable connections from machines that are not in domain but i get following errror when running the command in UnityVSA ssh console:

15:11:19 service@VIRT2242XPWCV1 spa:~/user# /nas/bin/.server_config ALL -v "param NTsec logonOptions=0x2d"
-rbash: /nas/bin/.server_config: restricted: cannot specify `/' in command names
15:12:12 service@VIRT2242XPWCV1 spa:~/user# cd /
-rbash: cd: restricted

VNXe/Unity:
Get root shell first, then run the .server_config command to change the parameter on the fiy:
/nas/bin/.server_config ALL -v "param NTsec logonOptions=0x2d"

Update the param files for SVDM_A and SVDM_B:
vi /nas/server/slot_2/param
vi /nas/server/slot_3/param

add the following line:
param NTsec logonOptions=0x2d

Run build config to ensure the changes persist upon reboot:
/nas/sbin/build_config /nas/server/slot_2 /nas/dos/slot_2
/nas/sbin/build_config /nas/server/slot_3 /nas/dos/slot_3
