Symptome
1- Cluster has a directory (.ssh) with advanced ACL applied to it.
2-Changing the permission to "700" using chmod will not take effect.
Cluster-1# ls -l total 296 -rwxr-x--- + 1 150xxx admin 10270 Mar 31 22:14 .sh_history drwxr-x--- + 2 150xxx admin 114 Mar 30 18:15 .ssh >>>"+" indicates that Advance ACLs are applied to the directory. Cluster-1# ls -led .ssh drwxr-x--- + 2 150xxx admin 114 Mar 30 18:15 .ssh OWNER: user:150xxx GROUP: group:admin CONTROL:dacl_auto_inherited,sacl_auto_inherited 0: user:150xxx allow dir_gen_read,dir_gen_write,dir_gen_execute,std_write_dac,delete_child 1: group:admin allow std_read_dac,std_synchronize,dir_read_attr 2: everyone allow std_read_dac,std_synchronize,dir_read_attr 3: group:admin allow inherited dir_gen_read,dir_gen_execute,read_write_sacl,inherited_ace 4: creator_group allow inherited dir_gen_read,dir_gen_execute,read_write_sacl,object_inherit,container_inherit,inherit_only,inherited_ace 5: user:150xxx allow inherited dir_gen_all,inherited_ace 6: creator_owner allow inherited dir_gen_all,object_inherit,container_inherit,inherit_only,inherited_ace
2-Changing the permission to "700" using chmod will not take effect.
#Cluster-1#chmod 700 .ssh Cluster-1# Cluster-1# ls -l total 296 -rwxr-x--- + 1 150xxx admin 10270 Mar 31 22:14 .sh_history drwxr-x--- + 2 150xxx admin 114 Mar 30 18:15 .ssh <<ADV ACL remains the same >>
Ursache
Synthetic ACL must be applied to the desired directory.
Lösung
-Adding "- b" option would apply the synthetic permission to the directory
Cluster-1# chmod -b 700 .ssh Cluster-1# Cluster-1# Cluster-1# ls -l total 296 -rwxr-x--- + 1 150xxx admin 10270 Mar 31 22:14 .sh_history drwx------ 2 150xxx admin 114 Mar 30 18:15 .sshAttention: Do take consent from customers about the change that will take place.
