PPP sur easynet : la config de David ROCHER

--- /usr/local/bin/ppcall ---
#!/bin/sh
if [ $# = "1" ]
then
	target=$1
else
	target=easynet
fi
exec /usr/sbin/pppd connect "/usr/sbin/chat -f /etc/ppp/Links/$target/chat" ipparam $target \
	oipdefault defaultroute 57600 /dev/ttyS0
--- /usr/local/bin/ppcall ---
il supporte le multilinks (tres utile ;-).

le chat script associe au link Easynet est :
--- /etc/ppp/Links/easynet/chat ---
REPORT          CONNECT
ABORT           BUSY
ABORT           ERROR
ABORT           "NO DIALTONE"
ABORT           "NO CARRIER"
""		AT&F&K3S25=20%E1%X4W2
OK\r		ATDT0561163866
CONNECT		""
ogin:		<user>
sword:		<password>
--- /etc/ppp/Links/easynet/chat ---
le numero de telephone est celui du POP de Toulouse et la chaine d'init
est pour un Olitec fax pocket 33.6.

de plus, j'ai les options suivates pour pppD:
--- /etc/ppp/options ---
asyncmap 0
crtscts
lock
modem
-pap
lcp-echo-interval 30
lcp-echo-failure 4
-ipx-protocol
--- /etc/ppp/options ---

le parametre ipparam permet aux scripts ip-up et ip-down appeles par pppd 
de faire des actions specifiques au up-link :
--- /etc/ppp/ip-up ---
#!/bin/sh
#
# This script is called with the following arguments:
#    Arg  Name               Example
#    $1   Interface name     ppp0
#    $2   The tty            ttyS1
#    $3   The link speed     38400
#    $4   Local IP number    12.34.56.78
#    $5   Peer  IP number    12.34.56.99
#    $6   IP param	     un petit texte

# The  environment is cleared before executing this script
# so the path must be reset
PATH=/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin
export PATH

# log le debut de la connexion
echo "$6 up at   `date "+%X"`" >> /etc/ppp/connect-errors

# modifie les parametres du resolver
if [ -f /etc/ppp/Links/$6/resolv.conf ]; then
	cp -fp /etc/ppp/Links/$6/resolv.conf /etc/resolv.conf
fi

# execute des commandes specifiques
if [ -x /etc/ppp/Links/$6/actions ]; then
	/etc/ppp/Links/$6/actions
fi
# last line
--- /etc/ppp/ip-up ---

--- /etc/ppp/ip-down ---
#!/bin/sh
#
# This script is called with the following arguments:
#    Arg  Name               Example
#    $1   Interface name     ppp0
#    $2   The tty            ttyS1

# The  environment is cleared before executing this script

PATH=/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin
export PATH

# log la fin de la connection
echo "$6 down at `date "+%X"`" >> /etc/ppp/connect-errors

# retablit les parametres par defaut
if [ -f /etc/ppp/Links/resolv.conf ]; then
	cp -fp /etc/ppp/Links/resolv.conf /etc/resolv.conf
fi
# last line
--- /etc/ppp/ip-down ---

pour les Easynet, le script actions est :
--- /etc/ppp/Links/easynet/actions ---
#!/bin/bash
# le mail sortant avec sendmail
/usr/sbin/sendmail -q
# le mail entrant avec fetchmail
/bin/su - <non_user> -c "/usr/bin/fetchmail"
# les news avec leafnode
/bin/su news -c "/usr/sbin/fetch"
--- /etc/ppp/Links/easynet/actions ---

RQ: pour sendmail, il faut utiliser le mode expensive pour le SNTP.

le resolver est mis a jour par ip-up et ip-down.
celui pour easynet est :
--- /etc/ppp/Links/easynet/resolv.conf ---
domain easynet.fr
nameserver 195.114.64.193
nameserver 193.131.248.2
--- /etc/ppp/Links/easynet/resolv.conf ---

ceci permet une connexion direct chez easynet. les points
sensibles sont la chaine d'init du modem, le login/password
du chat script.
