Configuring cache only DNS server on Solaris 10

        // If there is a firewall between you and nameservers you want
        // to talk to, you might need to uncomment the query- source
        // directive below. Previous versions of BIND always asked
        // questions using port 53, but BIND 8.1 and later use an unprivileged
        // port by default.

        // query-source address * port 53;

        // If your ISP provided one or more IP addresses for stable
        // nameservers, you probably want to use them as forwarders.
        // Uncomment the following block, and insert the addresses replacing
        // the all-0's placeholder.

        // forwarders {
        // 0.0.0.0;

Solaris 10 で DHCP
この手順どうもうまくいかないでつ。
Solaris10でDHCPサーバ構築
Swing実装のGUIプログラム(/usr/sadm/admin/bin/dhcpmgr )があるじゃん。

ついでにSolaris10をブロードバンドルータにするか。 DSL サポート用の PPPoE トンネルの作成
