Hi there,
first of all I think I must say sorry for my language skill.
Recently I had built pgcluster-1.9.0rc2 from sources and it works just
fine; some days ago however I gave a try for 1.9.0rc5 and found that
pglb isn't working at all. I made a diff between these versions for
src/pgcluster/pglb and saw a big redesign, it just scared me, and so I
decided to ask here for help.
So, I've setup two nodes with similar configurations (see attach for
explicit config files).
I've found that clusters is up and running, replication between them
seems to work fine, but when I connect to pglb port it says
[fisher at rabbit lib]# psql -h 192.168.8.89 -p 5432 -U postgres postgres
psql: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
In log file (pglb.log) I see these lines:
Sat Mar 22 15:09:27 2008
PGRset_status_on_cluster_tbl():host:192.168.8.89 port:5433 max:32 use:0

user:
Sat Mar 22 15:09:39 2008 PGRdo_child(): SSLRequest: sent N; retry
startup
...and that's all. Connection is closed.
I feel like I forgot something or doing something wrong, but I am stuck
here and need some advice. Please help me =)

# 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 [OPTION]
# host DATABASE USER CIDR-ADDRESS METHOD [OPTION]
# hostssl DATABASE USER CIDR-ADDRESS METHOD [OPTION]
# hostnossl DATABASE USER CIDR-ADDRESS METHOD [OPTION]
#
# (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 of significant bits in the mask. Alternatively, you can write
# an IP address and netmask in separate columns to specify the set of hosts.
#
# METHOD can be "trust", "reject", "md5", "crypt", "password", "gss", "sspi",
# "krb5", "ident", "pam" or "ldap". Note that "password" sends passwords
# in clear text; "md5" is preferred since it sends encrypted passwords.
#
# OPTION is the ident map or the name of the PAM service, depending on METHOD.
#
# Database and user names containing spaces, commas, quotes and other special
# characters must be quoted. Quoting one of the keywords "all", "sameuser" or
# "samerole" 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
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
host all all 192.168.8.0/24 trust
host all all 62.149.13.100/32 trust
