PPPoE Setup

# Install the PPP client protocol support and PPPoE cliet
yum install ppp rp-pppoe

# Add the username details to the CHAP/PAP PPP auth files /etc/ppp/chap-secrets and/or /etc/ppp/pap-secrets:

"myuser@realm.net"       *       "secret_password"

The PPPoE client looks for interfaces called "ppp*". Create ppp0 and specify the Ethernet interface is should use:

cat /etc/sysconfig/network-scripts/ifcfg-ppp0
TYPE=xDSL
DEVICE=ppp0
BOOTPROTO=dialup
USERCTL=no
IPV6INIT=no
PEERDNS=yes
PIDFILE=/var/run/pppoe-adsl.pid
FIREWALL=NONE
PING=.
PPPOE_TIMEOUT=30
LCP_FAILURE=3
LCP_INTERVAL=20
CLAMPMSS=1440
CONNECT_POLL=6
CONNECT_TIMEOUT=60
PERSIST=no
SYNCHRONOUS=no
DEFROUTE=yes
USER=myuser@realm.net
ETH=enp2s0
#PROVIDER=provider
DEMAND=no
ONBOOT=yes

The PPPoE client installs a bunch of scrtips:

[root@MaestrOS network-scripts]# which adsl-start
/sbin/adsl-start
[root@MaestrOS network-scripts]# which adsl-stop
/sbin/adsl-stop
[root@MaestrOS network-scripts]# ls -l /sbin/adsl*
