F.2 運用管理サーバにIPv6が設定されている場合の運用設定時の注意事項

構築済みの運用管理サーバにIPv6の設定を行う場合、運用管理クライアントから運用管理サーバに接続できない場合があります。その場合は、以下の手順で運用管理サーバに設定を行う必要があります。

1.  運用管理サーバにroot権限でログインします。

2.  以下のコマンドを実行し、IPv6のIPアドレスおよびサブネットマスク値を確認します。

# ifconfig -a

3.  「2.」で確認したIPv6のIPアドレスおよびサブネットマスク値を以下のファイルに設定します。

・設定ファイル:$DIR/FJSVnett/postgres/data/pg_hda.conf
($DIR:Systemwalker Network Managerのインストールディレクトリ)

4.  運用管理サーバを再起動します。再起動の手順は10.2.2.5 運用管理サーバの再起動を参照して下さい。

参考

  • 「3.」の設定例を以下に示します。IPv6のIPアドレスが「fec0::1:280:17ff:fe28:ac21/64」の場合の設定例を示します。最終行を以下のように修正して下さい。

# PostgreSQL Client Authentication Configuration File
# ===================================================
#
# Refer to the PostgreSQL Administrator's Guide, chapter "Client
# Authentication" for a complete description. 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 seven forms:
#
# local DATABASE USER METHOD [OPTION]
# host DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# hostssl DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# hostnossl DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# host DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
# hostssl DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
# hostnossl DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
#
# (The uppercase quantities should 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", "samegroup", a database name (or
# a comma-separated list thereof), or a file name prefixed with "@".
# USER can be "all", an actual user name or a group name prefixed with
# "+" or a list containing either. IP-ADDRESS and IP-MASK specify the
# set of hosts the record matches. CIDR-MASK is an integer between 0
# and 32 (IPv6) or 128(IPv6) inclusive, that specifies the number of
# significant bits in the mask, so an IPv4 CIDR-MASK of 8 is equivalent
# to an IP-MASK of 255.0.0.0, and an IPv6 CIDR-MASK of 64 is equivalent
# to an IP-MASK of ffff:ffff:ffff:ffff::. METHOD can be "trust", "reject",
# "md5", "crypt", "password", "krb4", "krb5", "ident", or "pam". Note
# that "password" uses clear-text passwords; "md5" is preferred for
# encrypted passwords. OPTION is the ident map or the name of the PAM
# service.
#
# 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, or use
# "pg_ctl reload".

# Put your actual configuration here
# ----------------------------------
#
# CAUTION: The default configuration allows any local user to connect
# using any PostgreSQL user name, including the superuser, over either
# Unix-domain sockets or TCP/IP. If you are on a multiple-user
# machine, the default configuration is probably too liberal for you.
# Change it to use something other than "trust" authentication.
#
# If you want to allow non-local connections, you need to add more
# "host" records. Also, remember TCP/IP connections are only enabled
# if you enable "tcpip_socket" in postgresql.conf.

# TYPE DATABASE USER IP-ADDRESS IP-MASK   METHOD

local all all trust
# IPv4-style local connections:
host all all 192.168.1.0 255.255.255.0 trust
# IPv6-style local connections:
host all all fec0::1:280:17ff:fe28:ac21/64 trust

注意

  • IPv6が設定されている環境にSystemwalker Network Managerはインストールできません。IPv6の設定を削除後にSystemwalker Network Managerのインストールを実施して下さい。インストール実施後に本節を参考にIPv6の再設定を実施して下さい。
