Summary: wins/smbfs/cifs name resolution for AFFA
QA Contact: [email protected]
Severity: normal
Classification: Contribs
OS: ---
Reporter: [email protected]
Hardware: ---
Status: UNCONFIRMED
Version: 8.0
Component: smeserver-affa
Product: SME Contribs
After upgrading to sme version 8, the affa backup jobs pulling data from
workstations to the backup server failed. The reason had to do with smb/cifs
name resolution and is easily fixed: add 'wins' to the 'hosts:'-line in
nsswitch.conf. Those interested please find details below.
Initially, backup jobs failed with this report:
Mon_Jun__4_17:30:01[27802]:_Mounting_//WINXP-ID/c$_to_/mnt/id
Mon_Jun__4_17:30:01[27802]:_Exec_Out:_mount:_unknown_filesystem_type_'smbfs'
The reason was that smbmount is no longer available. Switching to cifs...
db affa setprop id AutomountOptions '-t smbfs -o credentials=...'
to
db affa setprop id AutomountOptions '-t cifs -o credentials=...'
...brought back the old problem that netbios names were not resolved and
(fixed) IP-addresses needed:
Mon_Jun__4_19:38:32[30025]:_Mounting_//WINXP-ID/c$_to_/mnt/id
Mon_Jun__4_19:38:32[30025]:_Exec_Out:_mount_error:_could_not_resolve_address_for_WINXP-ID:_Name_or_service_not_known
Mon_Jun__4_19:38:32[30025]:_Exec_Out:_No_ip_address_specified_and_hostname_not_found
Reading a couple of bug reports on related issues taught me that sme server
resolves hostnames by consulting the hosts file and dns but not wins. Editing
/etc/nsswitch.conf...
hosts: files dns
to
hosts: files dns wins
...solves the problem.
Maybe the wins name resolution should be added as default to prevent this and
similar problems?
I found it confusing that “ping 'netbios-name'” works on the workstations but
not on the server, even though the server 'sees' the workstations' netbios
names when the smbtree command is used.
