SMB 1.0 Disabled for USGS

The following GPO was linked to all computers last night:  Bureau Enterprise Configurations – SMB 1.0 Disable

If sites are experiencing issues with SAMBA shares on their UNIX servers, they are reminded to use the following guidance to switch their servers to SMB 2.0:

To:             All WRD SAs (GS-W SA All)

From:           Sun TAC

Date:           June 28, 2017

Subject:        UPDATE: Samba Protocol SMBv2

 o Update Samba Protocol SMBv2

This All-SA email is an update to the following all-SA

email sent on March 3, 2017.

http://unix.usgs.gov/solaris/sa_notes/disnote.170303

Recently a GPO disabling SMBv1 has been applied at the USGS

level.  The previous all-SA email had sites enable SMBv2

in preparation for this change.  The following update

goes a step further and has sites disable SMBv1 in samba

on Solaris servers.  Verify the /etc/samba/smb.conf

configuration file has the folloiwng max and min

protocol settings.  If either or both are missing

add them in the “global” section and disable/enable

samba.

 

## Enable support for SMBv2, disable support for SMBv1.

min protocol = SMB2

max protocol = SMB2

 

Refresh the samba service and restart it.

 

svcadm refresh samba

svcadm restart samba

 

 

NOTE: If any users are experiencing problems accessing samba

shares have them remove and re-create their drive mapping.

 

 

Please email GS-W help sun with questions.
