Configuring pppoe on Solaris for BSNL DataONE broadband

In some areas in India one need to configure pppoe for connecting BSNL DataONE broadband.So here is a reference quick guide to setup pppoe for BSNL DataONE on Solaris. (This is not restricted to BSNL, it should be applicable to any service which is based on pppoe.)

SUNW ppp packages should be already available for you unless you didn't install.If you didn't install you need the following packages. Install them from your Solaris CD.

Packages

SUNWpppd  - Solaris PPP Device Drivers.
SUNWpppdr - Solaris PPP configuration files.
SUNWpppdt - Solaris PPP Tunneling.
SUNWpppdu - Solaris PPP daemon and utilities.

There will be a file myisp.tmpl in /etc/ppp/peers directory. copy the file to a filename /etc/ppp/peers/bsnl

~# cp /etc/ppp/peers/myisp.tmpl /etc/ppp/peers/bsnl

Note the conventions

USERNAME       - is your BSNL id eg (sampleid)
PASSWORD       - provided by bsnl (******)
INTERFACENAME  - is your ethernet card name eg (bge0,iprb0....) 

Edit /etc/ppp/peers/bsnl file using you favorite editor. The uncommented section should look like the following. where INTERFACE should be your ethernet interface name and USERNAME is your broadband user name.

connect "/usr/bin/chat -f /etc/ppp/myisp-chat"  # dial into ISP.<br>
sppptun
plugin pppoe.so
connect "/usr/lib/inet/pppoec INTERFACE"
user USERNAME           # my account name at my ISP
remotename bsnl # name of the ISP; for pap-secrets
noauth                  # do not authenticate the ISP's identity (client)
noipdefault             # assume no IP address; get it from ISP
defaultroute            # install default route; ISP is Internet gateway
updetach                # log errors and CONNECT string to invoker
noccp                   # ISP doesn't support free compression

Now there are 2 configuration files to that needs to be updated.

/etc/ppp/pap-secrets
/etc/ppp/chap-secrets

In these two files add the entry as follows

USERNAME        bsnl    PASSWORD

Where USERNAME is your broadband username and PASSWORD is you broadband password. Your configuration is almost done. Now for connecting.

#/usr/sbin/sppptun plumb pppoe INTERFACENAME
#/usr/sbin/sppptun plumb pppoed INTERFACENAME
#/usr/bin/pppd debug call bsnl

(debug is optional.)

you need to specify dns server to resolve dns names. create a file in /etc with name /etc/resolv.conf and copy the nameserver info. for example:

echo nameserver  61.1.96.69 > /etc/resolv.conf

Note: The IP specified here is BSNL nameserver, but might be different for you. Please ask your BSNL operator dns file. Or you can use the opendns.com server IP.

cp /etc/nsswitch.dns /etc/nsswitch.conf 

Make a backup copy so that you can copy back when needed next time.

cp /etc/resolv.conf /etc/resolv.conf.bsnl

In case you are still not able to resolv dns name. check if dns/client service is running or not.

svcs -a | grep dns/client

if not enabled

svcadm enable dns/client

if not online, try starting

svcadm restart dns/client
or
svcadm refresh dns/client

Simple script that can help you for connecting after configuring PPPoE.

#!/usr/bin/bash
ifconfig bge0 plumb
pkill -9 pppd
/usr/sbin/sppptun plumb pppoe bge0
/usr/sbin/sppptun plumb pppoed bge0
sleep 5 
/usr/bin/pppd debug call bsnl
echo nameserver 208.67.222.222 > /etc/resolv.conf
echo nameserver 208.67.220.220 >> /etc/resolv.conf
echo nameserver  61.1.96.69 >> /etc/resolv.conf
cp /etc/nsswitch.dns /etc/nsswitch.conf
svcadm restart dns/client
