RTX1100のIP設定

RARPでIPv4アドレスを設定する場合

以下を仮定。

RTX1100に設定するIPアドレス: 192.168.11.10/24
RTX1100の底面に書いてあるMACアドレス: xx:xx:xx:xx:xx:xx
USB-LANアダプタに設定するIPアドレス: 192.168.11.11/24
USB-LANのインタフェース名: en3

MacとRTX1100（LAN1）を接続
OS Xのネットワーク環境設定画面でUSB-LANアダプタの設定変更

（例）IPv4設定：手入力、IPアドレス：192.168.11.11、サブネットマスク：255.255.255.0

# ln -s /private/tftpboot/ /tftpboot
RTX1100に設定するIPアドレスの16進数表記を調べる

IP Address to Hex Converterなど
192.168.11.10 => 0xC0A80B0A

↑の16進数表記IPをもとに、ディレクトリorファイルを/tftpboot````内に作成: # mkdir -p /tftpboot/C0A80B0A```

これやらないとrarpdでIP設定できない

# echo xx:xx:xx:xx:xx:xx rtx1100 >> /etc/ethers
# echo "192.168.11.10 rtx1100" >> /etc/hosts
RTX1100を起動する
# rarpd -d en3
RTX1100を再起動する

ターミナルにrarpd: got a packetが一回だけ出たらIP設定完了

# telnet 192.168.11.10

IPv6アドレスを用いる場合

以下を仮定。

USB-LANのインタフェース名: en3

MacとRTX1100（LAN1）を接続
# ping6 -I en3 ff02::2
(応答があったアドレスがRTX1100のIPv6アドレスなはずなので、そこにtelnet)

設定書き込み

無駄にL2TP/IPsecを有効化した。ほぼ YAMAHAサイト記載の設定コピペ。
