TACACS+ サーバ設定

LAC設定：Cisco Secure UNIX 

# ./ViewProfile -p 9900 -u rtp.cisco.com user = rtp.cisco.com{ 
service=ppp { 
protocol=vpdn { 
set tunnel-type=l2tp 
set tunnel-id=rtp_tunnel 
set ip-addresses="10.31.1.56" 
} 
} 

} 

# ./ViewProfile -p 9900 -u rtp_tunnel
user = rtp_tunnel{
password = chap "FGHIJ" 
service=ppp {
protocol=lcp {
} 
protocol=ip {
} 
} 

}

LNSの設定：Cisco Secure UNIX 

# ./ViewProfile -p 9900 -u janedoe@rtp.cisco.com
user = janedoe@rtp.cisco.com{
password = chap "rtprules" 
service=ppp {
protocol=lcp {
} 
protocol=ip {
} 
} 

}
# ./ViewProfile -p 9900 -u ABCDE
user = ABCDE{
password = chap "FGHIJ" 
service=ppp {
protocol=lcp {
} 
protocol=ip {
}
}

}

LAC設定 – Cisco Secure Windows

Cisco Secure WindowsでLACを設定するには、次の手順を実行します。

  1. ユーザrtp_tunnelを通常のPPPユーザ（ユーザ設定のパスワードまたはCHAPパスワード）として設定します。

  2. ユーザをgroup_1に入れ、サービスPPP/IPをチェックします。このボックスが表示されている場合は、[PPP/LCP]をオンにします。

  3. ユーザrtp.cisco.comを設定します。パスワードは「Do not care」です。

  4. [グループ設定]に表示されていないオプションがある場合は、[インターフェイスの設定]に移動し、ボックスを選択して表示します。

  5. ユーザをgroup_2に入れ、サービスPPP/VPDNを確認します。tunnel-idはrtp_tunnel、ipアドレスリストは10.31.1.56で、その下にある長方形のカスタム属性ボックスにtunnel-type=l2tpと入力します。

LNSの設定：Cisco Secure Windows

Cisco Secure Windows用にLNSを設定するには、次の手順を実行します。

  1. ユーザ「ABCDE」および「janedoe@rtp.cisco.com」を通常のPPPユーザ（ユーザ設定のパスワードおよびCHAPパスワード）として設定します。

  2. ユーザをgroup_3に入れ、サービスPPP/IPをチェックします。このボックスが表示されている場合は、[PPP/LCP]をオンにします。

LAC TACACS+フリーウェア設定 

user = rtp.cisco.com {
service = ppp protocol = vpdn {
tunnel-type = l2tp
tunnel-id = rtp_tunnel
ip-addresses = "10.31.1.56"
}
}

user = rtp_tunnel {
chap = cleartext "FGHIJ"
service = ppp protocol = ip {
default attribute = permit
}
}

LNS TACACS+フリーウェア設定 

key = "cisco"

user = janedoe@rtp.cisco.com {
chap = cleartext "rtprules"
service = ppp protocol = ip {
default attribute = permit
}
}

user = ABCDE {
chap = cleartext "FGHIJ"
service = ppp protocol = ip {
default attribute = permit
}
}
