PPPoEの設定
下記コマンドでプロバイダーの接続ID・パスワードなどを設定する。
# pppoe-setup
プロバイダーの接続IDを指定
Welcome to the PPPoE client setup. First, I will run some checks on your system to make sure the PPPoE client is installed properly... LOGIN NAME Enter your Login Name (default root): [プロバイダーの接続ID]
ens192にPPPoE接続を割り当てる
INTERFACE Enter the Ethernet interface connected to the PPPoE modem For Solaris, this is likely to be something like /dev/hme0. For Linux, it will be ethX, where 'X' is a number. (default eth0): ens192
常時接続環境の場合はデフォルトno
そのままエンター
Do you want the link to come up on demand, or stay up continuously? If you want it to come up on demand, enter the idle time in seconds after which the link should be dropped. If you want the link to stay up permanently, enter 'no' (two letters, lower-case.) NOTE: Demand-activated links do not interact well with dynamic IP addresses. You may have some problems with demand-activated links. Enter the demand value (default no):
/etc/resolv.confを参照してほしいので
そのままエンター
DNS Please enter the IP address of your ISP's primary DNS server. If your ISP claims that 'the server will provide dynamic DNS addresses', enter 'server' (all lower-case) here. If you just press enter, I will assume you know what you are doing and not modify your DNS setup. Enter the DNS information here:
プロバイダーの接続パスワードを入力
PASSWORD Please enter your Password: [プロバイダーの接続パスワード]
一般ユーザーでも接続できるのか という設定だと思う。
とりあえずyesにしておく。
USERCTRL Please enter 'yes' (three letters, lower-case.) if you want to allow normal user to start or stop DSL connection (default yes):
ファイヤーウォールの設定
firewalld側で設定するのでとりあえず0を指定
FIREWALLING Please choose the firewall rules to use. Note that these rules are very basic. You are strongly encouraged to use a more sophisticated firewall setup; however, these will provide basic security. If you are running any servers on your machine, you must choose 'NONE' and set up firewalling yourself. Otherwise, the firewall rules will deny access to all standard servers like Web, e-mail, ftp, etc. If you are using SSH, the rules will block outgoing SSH connections which allocate a privileged source port. The firewall choices are: 0 - NONE: This script will not set any firewall rules. You are responsible for ensuring the security of your machine. You are STRONGLY recommended to use some kind of firewall rules. 1 - STANDALONE: Appropriate for a basic stand-alone web-surfing workstation 2 - MASQUERADE: Appropriate for a machine acting as an Internet gateway for a LAN Choose a type of firewall (0-2): 0
1,2の場合は接続時に下記スクリプトが実行されるので
細かい設定が出来る。
例えば、マルチホーミング時のゲートウェイの設定とか
/etc/ppp/firewall-masq /etc/ppp/ip-up
設定を保存しますか？
yを設定
** Summary of what you entered ** Ethernet Interface: ens192 User name: 50921_01@n-f.ipq.jp Activate-on-demand: No DNS: Do not adjust Firewalling: NONE User Control: yes Accept these settings and adjust configuration files (y/n)? y
以上で設定完了。
ifcfg-ppp0が生成される。
/etc/sysconfig/network-scripts/ifcfg-ppp0
カーネルモードの方が負荷がかからなく、速度も出るらしいので設定する。
# vi /etc/sysconfig/network-scripts/ifcfg-ppp0
