2 Installing PPP on an Ultrix system requires rebuilding the kernel and
3 rebooting, in addition to making and installing the pppd and chat
4 programs. These instructions apply to RISC (MIPS) systems. This
5 software has been tested under Ultrix 4.4; it should also work under
9 Kernel installation procedure.
10 ******************************
12 If you have not previously had an earlier version of this package
13 installed in the kernel, follow these steps:
17 2. Apply the patches in the file ultrix/patches using the command:
19 patch -p -N <ultrix/patches
21 This will edit the following files, saving the original versions in a
22 file with `.orig' appended to the name:
26 /usr/sys/net/net/netisr.h
27 /usr/sys/net/net/conf_net.c
28 /usr/sys/data/pseudo_data.c
29 /usr/sys/data/tty_conf_data.c
30 /usr/sys/conf/mips/files.mips
32 Alternatively, edit these files according to the differences shown in
35 3. Copy the following files to /sys/io/netif:
47 4. Add a line like this to the configuration file for your kernel:
51 The `2' indicates the number of interfaces desired. The configuration
52 file should be in /usr/sys/conf/mips.
54 5. Rebuild your kernel. The simplest way to do this is with the
55 `doconfig' command, like this:
57 /etc/doconfig -c kernel-name
59 where `kernel-name' should be replaced by the name of your kernel
60 configuration file. Alternatively, run config, cd to the compilation
61 directory, and run make.
63 6. Copy the new /vmunix to /. It would be a good idea to keep a copy
64 of your old /vmunix in / under a different name.
70 If you have ppp-2.1.2 or earlier already installed in your kernel,
71 some files will already have been modified as required. The files
72 which still need to be modified are:
74 /usr/sys/net/net/netisr.h
75 /usr/sys/net/net/conf_net.c
76 /usr/sys/conf/mips/files.mips
78 The file ultrix/upgrade is a patch file to modify these files. The
79 upgrade procedure is much the same as the installation procedure
80 described above, except that you use ultrix/upgrade in step 2 instead
81 of ultrix/patches, and step 4 should already have been done.
83 Earlier versions of ppp-2.x replaced if.o with a modified version.
84 This version does not need the modifications, so you can use either
85 the original or the modified version.
88 Installing pppd and chat.
