Network card configuration
DNS resolvers configuration
Configuration file for pppoe
Stopping the connection
Using a firewall
This HOW-TO explains how to set up a DSL connection using the new kernel PPPOE support. The goal is to avoid installation of an external package (such as rp-pppoe) because it tends to be over-complicated, confusing, unreliable, outdated.
A proper kernel configuration, with of course ppp support and pppoe support - for example:
CONFIG_PPP=m CONFIG_PPP_ASYNC=m CONFIG_PPP_SYNC_TTY=m CONFIG_PPP_DEFLATE=m CONFIG_PPP_BSDCOMP=m CONFIG_PPPOE=m
This can be set to 'y' instead of 'm', according to your needs. You can
grep -i ppp /boot/linux-`uname -r`.config to check
you current kernel's options for ppp support.
If you compiled the support of your network card directly in the kernel, nothing is required here.If you compiled your network card as a kernel module, you must ensure to specify an alias like this in /etc/modprobe.conf
alias eth0 via-rhine
Ensure modules loading upon system booting by adding these lines in /etc/sysconfig/modules.d/site:
You might also need to specify ppp_generic if you built it as a modulevia-rhine is given as an example, replace it with the module name that corresponds to your hardware.
Now here is the configuration required by the network init service. Edit /etc/sysconfig/network.d/ifconfig.eth0/ipv4:
ONBOOT=yes SERVICE=ipv4-static IP=192.168.1.1 GATEWAY= PREFIX=24 BROADCAST=192.168.1.255
Edit /etc/resolv.conf with the values provided by your ISP. This is an example for the French ISP Wanadoo:
search wanadoo.fr nameserver 22.214.171.124 80.10.256.3
Edit /etc/ppp/pap-secrets and /etc/ppp/chap-secrets:
"your_isp_login" * "password"
Edit /etc/host.conf with:
order hosts,bind multi on
You must tell ppp to use the plugin rp-pppoe (installed with the ppp package) in /etc/ppp/options:
plugin rp-pppoe.so name <your ISP login name> noipdefault defaultroute mtu 1492 mru 1492 lock
That's all, you are all done! To bring up the DSL line, just type:
/usr/sbin/pppd-stopThis command doesn't come with ppp, we added it for convenience, credits does to
Using a firewall is almost mandatory with DSL lines. Formerly rp-ppoe bundled firewall scripts, we discourage their use at the benefit of either a dedicated software, or our own firewall service 'nanofw' (we bundles it with iptables):
chmod +x /etc/init.d/runlevel.3/nanofw # if you wan to setup NAT (connection sharing): nano /etc/sysonfig/nanofw # Edit the four values of the NAT section # now run it: telinit nanofw start
