If the PPP client calling the server already has a static IP address on some remote network, make sure the dummy IP address assigned to the server will not conflict with another valid IP on the PPP client’s network. Replace the string remotehostIP with the IP address of the PPP client. If it is going to be used as a stand-alone machine, then make up a dummy IP address. Note: If the PPP server is networked, then it should already have an IP address, and you must replace the string localhostIP with it. ppprc in /home/ppp and add the following lines: Edit the file only to modify the shell, after the account has been created through the control panel.Ĭreate the file. Note: Do not edit the /etc/passwd file to create the ppp account. After the ppp login authentication process has completed, the remote server will start the pppd process automatically instead of the normal shell. This is not a recognized shell by the user configuration control panel and this is why the /etc/passwd file has to be edited separately. Close the configuration panel and activate the changes.Įdit the /etc/passwd file and replace the default shell with /usr/sbin/pppd. Do not make any changes to the default shell at this time. Set the password, user information, and create the /home/ppp directory. Using the user configuration panel, create a new user ppp. Re-boot the machine and the mgetty process will be started automatically by the inittab master process. Note that the –D option is important as it forces mgetty to treat the modem as a DATA modem. This port should be dedicated to incoming calls and not be used to interface with any other devices (such as a UPS serial connection). Where # is the number of the port which will be monitored by the mgetty process. Setup procedure for PPP server (dial-in):ĭ1:2345:respawn:/sbin/mgetty –D /dev/ttyS# Follow steps in HOWTO.2 and make sure the remote computer is sending a clean login prompt to your screen. Note: It is a good idea to set up a basic dial-up connection and check that the serial link and mgetty program are functioning properly.
