The sections below discuss how to set up the PPP configuration files from SLIP configuration files. Three types of SLIP configurations are used as examples.

Case 1: Dialout SLIP Connection without UUCP System Name

This type of connection is represented by an entry in /etc/ppl/ppl.remotes where type=DIALOUT, modem_control=YES and there is no uucp_system name. The migration task involves creating an entry in both /etc/ppp/Systems and /etc/ppp/Devices using information from /etc/ppl/ppl.remotes and /etc/uucp/Devices.

SLIP Configuration

/etc/ppl/ppl.remotes

The dialout SLIP connection without a UUCP system name is defined in /etc/ppl/ppl.remotes by:

keywest

# remote host name or IP address

ewok

# local hostname or IP address

# Internet mask

SLIP

# protocol [SLIP] [ASLIPC] [ASLIPS] [PPP] [CSLIPA] [CSLIP]

DIALOUT

# type [DIRECT] [DIALIN] [DIALOUT] [DIALIN & DIALOUT]

# UUCP system name

NONE

# line parity [EVEN] [ODD] [NONE]

9600

# line speed

cul1b1

# serial line

89659

# phone number

YES

# modem control available [YES] [NO]

login: test password: blue

# log in info

"" ppl\s-i\s ewok

# command name

/etc/uucp/Devices

The dialout SLIP connection is defined in /etc/uucp/Devices by:

ACU cul1b1 - 9600 hayes
Command Line

The command line for the dialout SLIP connection is:

ppl -o keywest

PPP Configuration

/etc/ppp/Systems

Information in the /etc/ppp/Systems file corresponds to the following information from the /etc/ppl/ppl.remotes file:

/etc/ppp/Systems/etc/ppl/ppl.remotes
nameremote host name (keywest)
whenset to Any
deviceset to ACU
speedline speed (9600)
phonephone number (89659)
chat_scriptlog in info (login: test password: blue)

After migration, the dialout PPP connection is defined in /etc/ppp/Systems by:

keywest   Any   ACU   9600   89659   in:--in: test word: blue
/etc/ppp/Devices

An entry in /etc/ppp/Devices is created by searching the /etc/uucp/Devices file with an entry corresponding to an entry with device_type=ACU, device_file=serial_line from ppl.remotes, and speed=speed from /etc/ppl/ppl.remotes. The /etc/ppp/Devices entry is created using the following information from /etc/uucp/Devices entry.

/etc/ppp/Devices/etc/uucp/Devices
dialerdialer_token (hayes)
devicedevice_file (cul1b1)
speedspeed (9600)

After migration, the dialout PPP connection is defined in /etc/ppp/Devices by:

hayes   cul1b1   9600
/etc/ppp/Autostart

The /etc/ppp/Autostart entry for the dialout PPP connection is:

pppd  ewok:keywest  auto  idle  350

Case 2: Direct SLIP Connection without UUCP System Name

This type of connection is represented by an entry in /etc/ppl/ppl.remotes by type=DIRECT, modem_control=NO and no uucp_system name. The migration task involves creating an entry in both /etc/ppp/Systems and /etc/ppp/Devices using information from /etc/ppl/ppl.remotes and /etc/uucp/Devices.

SLIP Configuration

/etc/ppl/ppl.remotes

The direct SLIP connection without a UUCP system name is defined in /etc/ppl/ppl.remotes by the following:

keywest

# remote hostname or IP address

ewok

# local hostname or IP address

# Internet mask

SLIP

# protocol [SLIP] [ASLIPC] [ASLIPS] [PPP] [CSLIPA] [CSLIP]

DIRECT

# type [DIRECT] [DIALIN] [DIALOUT] [DIALIN & DIALOUT]

# UUCP system name

NONE

# line parity [EVEN] [ODD] [NONE]

57600

# line speed

tty1p0

# serial line

# phone number

NO

# modem control available [YES][NO]

# log in info

# command name

/etc/uucp/Devices

The direct SLIP connection is defined in /etc/uucp/Devices by:

Direct   tty1p0   -   57600   direct
Command Line

The command line for the direct SLIP connection is:

ppl -o keywest

PPP Configuration

/etc/ppp/Systems

Information in the /etc/ppp/Systems file corresponds to the following information from the /etc/ppl/ppl.remotes file:

/etc/ppp/Systems/etc/ppl/ppl.remotes
nameremote host name (keywest)
whenset to Any
deviceserial line (tty1p0)
speedline speed (57600)

After migration, the direct PPP connection is defined by:

keywest   Any   tty1p0   57600
/etc/ppp/Devices

An entry in /etc/ppp/Devices will be created using the information from /etc/uucp/Devices.

/etc/ppp/Devices/etc/uucp/Devices
dialerset to Direct
devicedevice_file (tty1p0)
speedspeed (57600)

After migration, the direct PPP connection is defined by:

Direct   tty1p0   57600 
/etc/ppp/Autostart

The /etc/ppp/Autostart entry for the direct PPP connection is:

pppd ewok:keywest auto

Case 3: Dialout SLIP Connection with UUCP System Name

This type of connection is represented by an entry in /etc/ppl/ppl.remotes by type=DIALOUT, modem_control=YES and the presence of uucp_system name. The migration task involves creating an entry in both /etc/ppp/Systems and /etc/ppp/Devices using information from /etc/ppl/ppl.remotes, /etc/uucp/Systems, and /etc/uucp/Devices.

SLIP Configuration

/etc/ppl/ppl.remotes

The dialout SLIP connection is defined in /etc/ppl/ppl.remotes by the following:

keywest

# remote hostname or IP address

ewok

# local hostname or IP address

# Internet mask

SLIP

# protocol [SLIP] [ASLIPC] [ASLIPS] [PPP] [CSLIPA] [CSLIP]

DIALOUT

# type [DIRECT] [DIALIN] [DIALOUT] [DIALIN & DIALOUT]

kqu

# UUCP system name

NONE

# line parity [EVEN] [ODD] [NONE]

# line speed

# serial line

# phone number

YES

# modem control available [YES][NO]

# log in info

# command name

/etc/uucp/Systems

The dialout SLIP connection is defined in /etc/uucp/Systems by:

kqu   ANY;1   ACU   9600   89659   login: test password: blueSky
/etc/uucp/Devices

The dialout SLIP connection is defined in /etc/uucp/Devices by:

kqu   cul1b1   -   9600   hayes
Command Line

The command line for the dialout SLIP connection is:

ppl -o keywest

PPP Configuration

/etc/ppp/Systems

The name for the /etc/ppp/Systems entry is taken from the remote host field in /etc/ppl/ppl.remotes. The rest of the information for the /etc/ppp/Systems entry is taken from the /etc/uucp/Systems file that corresponds to the UUCP system name defined in /etc/ppl/ppl.remotes (kqu):

/etc/ppp/Systems/etc/uucp/Systems
when; retrytime; retry (set to ANY) *
devicedevice (must be ACU)
speedspeed (9600)
phonephone (89659)
chat_scriptchat_script (login: test password: blueSky)

* A numerical value for retry in /etc/uucp/System must be converted to seconds.

After migration, the dialout PPP connection is defined in /etc/ppp/Systems by:

keywest  Any;1  ACU  9600  89659  login: test password: blueSky
/etc/ppp/Devices

An entry in /etc/ppp/Devices will be created by searching the /etc/uucp/Devices file with an entry corresponding to an entry with device_type=ACU, and speed=speed from /etc/uucp/Systems. The /etc/ppp/Devices entry will be created using the following information from /etc/uucp/Devices entry.

/etc/ppp/Devices/etc/uucp/Devices
dialerdialer_token (hayes)
devicedevice_file (cul1b1)
speedspeed (9600)

After migration, the dialout PPP connection is defined in /etc/ppp/Devices by:

hayes   cul1b1   9600
/etc/ppp/Autostart

The /etc/ppp/Autostart entry for the dialout PPP connection is:

pppd ewok:keywest auto idle 350
