[Samba] Bug 1465523 - smbd killed by SIGABRT daily

Tue Jul 4 14:30:42 UTC 2017

ok, start with : 

hosts:      files mdns4_minimal [NOTFOUND=return]  dns myhostname 
change that to 
hosts:      files dns myhostname  mdns4_minimal [NOTFOUND=return] 

( optional you can test also, hosts:      files mdns4_minimal [NOTFOUND=continue] dns myhostname) 

remove the create and directory mask. 
Now test again. 

Do you jave shares over nfs? or any other thing you can share about you setup. 
That would be helpfull. 

i dont know sssd but that conf is also needed, lets hope someing else know more about that. 

Greetz, 

Louis

/etc/nsswitch.conf

#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Valid entries include:
#
#       nisplus                 Use NIS+ (NIS version 3)
#       nis                     Use NIS (NIS version 2), also called YP
#       dns                     Use DNS (Domain Name Service)
#       files                   Use the local files
#       db                      Use the local database (.db) files
#       compat                  Use NIS on compat mode
#       hesiod                  Use Hesiod for user lookups
#       [NOTFOUND=return]       Stop searching if not found so far
#

# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd:    db files nisplus nis
#shadow:    db files nisplus nis
#group:     db files nisplus nis

passwd:     files sss
shadow:     files sss
group:      files sss

#hosts:     db files nisplus nis dns
hosts:      files mdns4_minimal [NOTFOUND=return] dns myhostname

# Example - obey only what nisplus tells us...
#services:   nisplus [NOTFOUND=return] files
#networks:   nisplus [NOTFOUND=return] files
#protocols:  nisplus [NOTFOUND=return] files
#rpc:        nisplus [NOTFOUND=return] files
#ethers:     nisplus [NOTFOUND=return] files
#netmasks:   nisplus [NOTFOUND=return] files

bootparams: nisplus [NOTFOUND=return] files

ethers:     files
netmasks:   files
networks:   files
protocols:  files
rpc:        files
