  • Description updated (diff)
  • Status changed from NEW to TRIAGED
  • % Done changed from 0 to 20

#3 Updated by Davide Principi over 6 years ago

Proposed solution:

  • drop WinsServerStatus prop
  • If the WinsServerIP prop is set to another server, set wins support = no, wins server = <VALUE>
  • If the WinsServerIP prop points to the server itself, or is not set at all:
    • if server role is PDC, set wins support = yes
    • in any other case, set wins support = no

The property WinsServerStatus is not present on a fresh install and it's removed when installing on an updated system: verified.

This test case is verified:

[root@localhost db]# config getprop smb  ServerRole 
WS

[root@localhost db]# grep wins /etc/samba/smb.conf 
wins support = No
wins server =

Even this one is verified:

[root@localhost db]# config getprop smb  ServerRole 
PDC
[root@localhost db]# grep wins /etc/samba/smb.conf 
wins support = Yes
wins server =

This test case is NOT verified: if the WinsServerIP is set, the value is lost if the server role is set to PDC.
The problem is caused by the migration fragment: /etc/e-smith/db/configuration/migrate/bug3013_ns6.5

If the server is PDC:

config setprop smb WinsServerIP 192.168.1.1
[root@localhost db]# grep wins /etc/samba/smb.conf 
wins support = Yes
wins server =

if the server is not PDC:

config setprop smb WinsServerIP 192.168.1.1
[root@localhost db]# grep wins /etc/samba/smb.conf 
wins support = No
wins server = 192.168.1.1
