Log Message:
- it is now possible to make the serial drivers pipe their input/output
  to programs by using a '|' followed by a command line as the modem or
  printer port setting (instead of a device name like '/dev/ttyS0')
  [Brian Johnson]
- the option "--config FILE" tells B2 to use a different config file

4 ==================================================

6 BasiliskII does not currently support networking natively on IRIX.
7 That is, the emulated Ethernet card does not do anything. There's no
8 reason one couldn't use raw domain sockets and the snoop(7p) facility
9 to do networking, but so far no one has written the required glue
10 code.
11
12 However, it is possible to do TCP/IP networking with BasiliskII on
13 IRIX via PPP, by connecting an emulated serial port to the IRIX PPP
14 daemon. Here are the steps to set it up:
15
16
17 Set up PPP on IRIX
18 ------------------
19
20 You need root privileges to do this.
21
22 First, make sure you have eoe.sw.ppp and eoe.sw.uucp installed:
23
24 IRIS# versions eoe.sw.ppp eoe.sw.uucp
25 I = Installed, R = Removed
26
27 Name Date Description
28
29 I eoe 07/22/2002 IRIX Execution Environment, 6.5.17m
30 I eoe.sw 07/22/2002 IRIX Execution Environment Software
31 I eoe.sw.ppp 07/22/2002 Point-to-Point Protocol Software
32 I eoe.sw.uucp 07/22/2002 UUCP Utilities
33
34 If they aren't installed, install them from your distribution CDs.
35
36 Next, pick IP addresses for the IRIX and MacOS sides of the PPP
37 connection. You may want to ask your local network administrator
38 about this, but any two unused addresses on your local subnet should
39 work.
40
41 Edit /etc/ppp.conf and add these three lines:
42
43 _NET_INCOMING
44 remotehost=<MacOS PPP IP address>
45 localhost=<IRIX PPP IP address>
46
47 (Replace the angle brackets and the text in them with the appropriate
48 IP addresses.)
49
50 Next, make a script to set up the environment properly when invoking
51 pppd from BasiliskII. You can name this whatever you want; I chose
52 /usr/etc/ppp-b2:
53
54 IRIS# whoami
55 root
56 IRIS# cat < /usr/etc/ppp-b2
57 #!/bin/sh
58 export USER=_NET_INCOMING
59 exec /usr/etc/ppp "$@"
60 IRIS# chmod 4775 /usr/etc/ppp-b2
61
62 Rewrite this in perl or python or C or whatever if you don't like
63 setuid shell scripts. The alternative is to run BasiliskII as root:
64 pppd _must_ be run as root.
65
66
67 Configure BasiliskII to start the PPP daemon
68 --------------------------------------------
69
70 Start up BasiliskII, and in the serial devices tab, enter:
71
72 |exec /usr/etc/ppp-b2
73
74 Supply the name you used for the script you created. Be sure to
75 include the leading pipe symbol ("|").
76
77 The "exec" causes your PPP startup script to replace the shell
78 BasiliskII runs to interpret the command. It's not strictly
79 necessary, but cuts down on the number of extra processes hanging
80 about.
81
82
83 Install a PPP client on MacOS
84 -----------------------------
85
86 The details of this step will vary depending on your PPP client
87 software. Set it up for a "direct" connection, with no modem chatting
88 or login scripting. For instance, with FreePPP I set the "Connect:"
89 item on the "Edit..." screen under the "Accounts" tab to "Directly".
90 Be sure to select the correct serial port. The serial port speed
91 shouldn't matter (BasiliskII ignores it), but I set it to 115200 bps.
92
93 Next, configure MacOS's TCP/IP stack. If you're using Open Transport,
94 Open the TCP/IP control panel and select "Using PPP Server" under the
95 "Configure" item. Copy IRIX's DNS client info. from /etc/resolv.conf
96 to the control panel: the addresses from the "nameserver" lines go in
97 the "Name server addr.:" box, and the domains from the "search" lines
98 go in the "Search domains:" box. The steps should be similar for
99 MacTCP.
100
101 Now fire up PPP. Your PPP client should establish communication with
102 the IRIX PPP daemon, and you're off and running.

108 I haven't tried this procedure from scratch on a freshly installed
109 system, so I might have missed a step somewhere. But it should get
110 you close....
