Earlier versions of the Solaris OS included a different PPP implementation, Asynchronous Solaris PPP (asppp). If you want to convert peers that run asppp to the newer PPP 4.0, you need to run a conversion script. This chapter covers the following topics in PPP conversion:Before Converting asppp Files Running the asppp2pppd Conversion Script (Tasks) The chapter uses a sample asppp configuration to explain how to accomplish PPP conversion. For a description of the differences between Solaris PPP 4.0 and asppp, go to Which Version of Solaris PPP to Use. You can use the conversion script /usr/sbin/asppp2pppd to convert the files that compose a standard asppp configuration:/etc/asppp.cf – Asynchronous PPP configuration file /etc/uucp/Systems – UUCP file that describes the characteristics of the remote peer /etc/uucp/Devices – UUCP file that describes the modem on the local machine /etc/uucp/Dialers – UUCP file that contains the login sequence to be used by the modem that is described in the /etc/uucp/Devices file For more information about asppp, see the Solaris 8 System Administration Collection, Volume 3, available from http://docs.sun.com.The procedure that is shown in How to Convert From asppp to Solaris PPP 4.0 uses the following /etc/asppp.cf file.# ifconfig ipdptp0 plumb mojave gobi up path inactivity_timeout 120 # Approx. 2 minutes interface ipdptp0 peer_system_name Pgobi # The name we log in with (also in # /etc/uucp/SystemsThe file contains the following parameters.ifconfig ipdptp0 plumb mojave gobi upRuns the ifconfig command to configure a link from PPP interface ipdptp0 on the local machine mojave to the remote peer gobi inactivity_timeout 120Terminates the line after two minutes of inactivity interface ipdptp0Configures the interface ipdptp0 on the dial-out machine for asynchronous PPP peer_system_name PgobiGives the name of the remote peer, Pgobi The procedure that is shown in How to Convert From asppp to Solaris PPP 4.0 uses the following /etc/uucp/Systems file.#ident "@(#)Systems 1.5 92/07/14 SMI" /* from SVR4 bnu:Systems 2.4 */ # # . # .

Any ACUTells the modem on the dial-out machine mojave to establish a link with a modem on Pgobi at any time of the day. Any ACU means “look for ACU in the /etc/uucp/Devices file.” 38400Sets 38400 as the maximum speed of the link. 15551212Gives the telephone number of Pgobi. in:—in: mojave word: sandDefines the login script that is required by Pgobi to authenticate dial-out machine mojave. The procedure that is shown in How to Convert From asppp to Solaris PPP 4.0 uses the following /etc/uucp/Devices file.#ident "@(#)Devices 1.6 92/07/14 SMI" /* from SVR4 bnu:Devices 2.7 */ . . # TCP,et - - Any TCP - . . # ACU cua/b - Any hayes # 0-7 are on a Magma 8 port card Direct cua/0 - Any direct Direct cua/1 - Any direct Direct cua/2 - Any direct Direct cua/3 - Any direct Direct cua/4 - Any direct Direct cua/5 - Any direct Direct cua/6 - Any direct Direct cua/7 - Any direct # a is the console port (aka "tip" line) Direct cua/a - Any direct # b is the aux port on the motherboard Direct cua/b - Any direct # c and d are high speed sync/async ports Direct cua/c - Any direct Direct cua/d - Any directThe file supports any Hayes modem that is connected to serial port cua/b. The procedure that is shown in How to Convert From asppp to Solaris PPP 4.0 uses the following /etc/uucp/Dialers file.# #<Much information about modems supported by Solaris UUCP> penril =W-P "" \d > Q\c : \d- > s\p9\c )-W\p\r\ds\p9\c-) y\c : \E\TP > 9\c OK ventel =&-% "" \r\p\r\c $ k\c ONLINE! vadic =K-K "" \005\p *-\005\p-*\005\p-* D\p BER? \E\T\e \r\c LINE develcon "" "" \pr\ps\c est:\007 \E\D\e \n\007 micom "" "" \s\c NAME? \D\r\c GO direct # # # # Hayes Smartmodem -- modem should be set with the configuration # switches as follows: # # S1 - UP S2 - UP S3 - DOWN S4 - UP # S5 - UP S6 - DOWN S7 - ?

The /usr/sbin/asppp2pppd script copies the PPP information in /etc/asppp.cf and PPP-related UUCP files to appropriate locations in the Solaris PPP 4.0 files. Before doing the next task, you should have done the following:Installed the Solaris 9 release or Solaris 10 release on the machine that also has the asppp and UUCP configuration files Become superuser on the machine with the PPP files, for example, the machine mojave Start the conversion script.# /usr/sbin/asppp2pppdThe conversion process starts and gives you the following screen output.This script provides only a suggested translation for your existing aspppd configuration. You will need to evaluate for yourself whether the translation is appropriate for your operating environment. Continue [Yn]? Type “Y” to continue.You receive the following output.Chat cannot do echo checking; requests for this removed. Adding 'noauth' to /etc/ppp/options Preparing to write out translated configuration: 1 chat file: 1. /etc/ppp/chat.Pgobi.hayes 2 option files: 2. /etc/ppp/peers/Pgobi 3. /etc/ppp/options 1 script file: 4. /etc/ppp/demandThe new Solaris PPP 4.0 files have been generated. You can view the Solaris PPP 4.0 files that were created by the /usr/sbin/asppp2pppd conversion script at the end of the conversion process. The script displays the following list of options.Enter option number: 1 - view contents of file on standard output 2 - view contents of file using /usr/bin/less 3 - edit contents of file using /usr/bin/vi 4 - delete/undelete file from list 5 - rename file in list 6 - show file list again 7 - escape to shell (or "!") 8 - abort without saving anything 9 - save all files and exit (default) Option: Type 1 to view the contents of the files on the screen. The script requests the number of the file you want to view.File number (1 .. 4):The numbers refer to the translated files that are listed during the conversion process, as shown in the previous Step 2. Type 1 to view the chat file /etc/ppp/chat.Pgobi.hayes.File number (1 .. 4): 1 "" \d\dA\p\pTE1V1X1Q0S2=255S12=255\r\c OK\r ATDT\T\r\c CONNECT \c in:--in: mojave word: sandThe chat script contains the modem “chat” information that appears on the hayes line in the sample /etc/uucp/Dialers file. /etc/ppp/chat.Pgobi.hayes also contains the login sequence for Pgobi that appears in the sample /etc/uucp/Systems file. The chat script is now in the /etc/ppp/chat.Pgobi.hayes file. Type 2 to view the peers file, /etc/ppp/peers/Pgobi. File number (1 .. 4): 2 /dev/cua/b 38400 demand idle 120 connect "/usr/bin/chat -f /etc/ppp/chat.Pgobi.hayes -T '15551212'" user NeverAuthenticate mojave:gobiThe serial port information (/dev/cua/b) is from the /etc/uucp/Devices file. The link speed, idle time, authentication information, and peer names are from the /etc/asppp.cf file. “demand” refers to the “demand” script, to be called when the dial-out machine tries to connect to peer Pgobi. Type 3 to view the /etc/ppp/options file that are created for dial-out machine mojave.File number (1 .. 4): 3 #lock noauthThe information in /etc/ppp/options is from the /etc/asppp.cf file. Type 4 to view the contents of the demand script.File number (1 .. 4): 4 /usr/bin/pppd file /etc/ppp/peers/PgobiThis script, when invoked, runs the pppd command, which then reads the /etc/ppp/peers/Pgobi to initiate the link between mojave and Pgobi. Type 9 to save the created files. Then exit the conversion script.
