[gpadmin@sgpc146 ~]$ vi $MASTER_data_dirECTORY/pg_hba.conf # Postgresql Client Authentication Configuration File # =================================================== # # Refer to the "Client Authentication" section in the Postgresql # documentation for a complete description of this file. A short # synopsis follows. # # This file controls: which hosts are allowed to connect,how clients # are authenticated,which Postgresql user names they can use,which # databases they can access. Records take one of these forms: # # local DATABASE USER METHOD [OPTIONS] # host DATABASE USER CIDR-ADDRESS METHOD [OPTIONS] # hostssl DATABASE USER CIDR-ADDRESS METHOD [OPTIONS] # hostnossl DATABASE USER CIDR-ADDRESS METHOD [OPTIONS] # # (The uppercase items must be replaced by actual values.) # # The first field is the connection type: "local" is a Unix-domain # socket,"host" is either a plain or SSL-encrypted TCP/IP socket,# "hostssl" is an SSL-encrypted TCP/IP socket,and "hostnossl" is a # plain TCP/IP socket. # # DATABASE can be "all","sameuser","samerole",a # database name,or a comma-separated list thereof. # # USER can be "all",a user name,a group name prefixed with "+",or a # comma-separated list thereof. In both the DATABASE and USER fields # you can also write a file name prefixed with "@" to include names # from a separate file. # # CIDR-ADDRESS specifies the set of hosts the record matches. It is # made up of an IP address and a CIDR mask that is an integer (between # 0 and 32 (IPv4) or 128 (IPv6) inclusive) that specifies the number "/data/master/gpseg-1/pg_hba.conf" 86L,4411C 1,1 Top # special characters must be quoted. Quoting one of the keywords # "all","samerole" or "replication" makes the name lose # its special character,and just match a database or username with # that name. # # This file is read on server startup and when the postmaster receives # a SIGHUP signal. If you edit the file on a running system,you have # to SIGHUP the postmaster for the changes to take effect. You can # use "pg_ctl reload" to do that. # Put your actual configuration here # ---------------------------------- # # If you want to allow non-local connections,you need to add more # "host" records. In that case you will also need to make Postgresql # listen on a non-local interface via the listen_addresses # configuration parameter,or via the -i or -h command line switches. # CAUTION: Configuring the system for local "trust" authentication allows # any local user to connect as any Postgresql user,including the database # superuser. If you do not trust all your local users,use another # authentication method. # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only # IPv4 local connections: # IPv6 local connections: local all gpadmin ident host all gpadmin 127.0.0.1/28 trust host all gpadmin 129.100.253.146/32 trust host all gpadmin 169.254.95.120/32 trust host all gpadmin ::1/128 trust host all gpadmin 2002:8164:fdd6:b:3640:b5ff:fea2:119c/128 trust host all gpadmin 2002:8164:fdde:b:3640:b5ff:fea2:119c/128 trust host all gpadmin fec0::b:3640:b5ff:fea2:119c/128 trust host all gpadmin fe80::3640:b5ff:fea2:119c/128 trust host all gpadmin fe80::3440:b5ff:fe9b:119f/128 trust host all all 0.0.0.0/0 trust "/data/master/gpseg-1/pg_hba.conf" 87L,4440C written [gpadmin@sgpc146 ~]$ gpstop -u 20110928:21:13:19:028768 gpstop:sgpc146:gpadmin-[INFO]:-Starting gpstop with args: -u 20110928:21:13:19:028768 gpstop:sgpc146:gpadmin-[INFO]:-Gathering information and validating the environment... 20110928:21:13:19:028768 gpstop:sgpc146:gpadmin-[INFO]:-Obtaining Greenplum Master catalog information 20110928:21:13:19:028768 gpstop:sgpc146:gpadmin-[INFO]:-Obtaining Segment details from master... 20110928:21:13:19:028768 gpstop:sgpc146:gpadmin-[INFO]:-Greenplum Version: 'postgres (Greenplum Database) 4.2.1.2 build 2' 20110928:21:13:19:028768 gpstop:sgpc146:gpadmin-[INFO]:-Signalling all postmaster processes to reload .
