Installation Instructions

1.  Install the kernel part of this distribution.  A reboot is not
    required.


2.  Examine the various makefiles in this directory and subdirectories
    and if all appears to be well, type "make install".


3.  Edit /etc/rc.local; You will need to add the following lines:

if [ -f /etc/x29d ]; then
        /etc/x29d -r -c 1980 "/bin/login login -f"              >/dev/console
        echo -n ' x29d'                                         >/dev/console
fi
if [ -f /etc/nimd ]; then
        /etc/nimd -c 1980 /dev/ptyq0                            >/dev/console
        /etc/nimd -c 1980 /dev/ptyq1                            >/dev/console
        /etc/nimd -c 1980 /dev/ptyq2                            >/dev/console
        echo -n ' nimd'                                         >/dev/console
fi

/etc/x29d is the call-in server and /etc/nimd is used for making out-calls
to other sites.  Removing the "-r" flag to x29d will cause the kernel X.25
software to clear incoming collect (ie. reverse charged) X.29 calls.
The exact number of nim daemons started, pseudo-tty devices used, and
parameter support are installation dependent.  This example starts
three daemons that support the 1980 CCITT ITI parameter set.


4. Optional: compile and install dist/bin/login.c (see makefile in that
   directory).  This modified login program more gracefully handles
   incoming X.29 calls.


5. If you run 'tip' then add these lines to /etc/remote:

nimd|pad|NIM Daemon:\
        :hw:dv=/dev/ttyq0,/dev/ttyq1,/dev/ttyq2:

Make sure that the 'dv' entry lists the slave devices corresponding to
the master pseudo-tty devices that the nim daemons are connected to.

Additional lines like the following can be added if you have the version
of tip locally modified at UBC and wish to simplify connection procedures
to other remote hosts:

datapacinfo|Datapac help:\
        :cm=NIM p\s92100086:tc=nimd:
ubcg-mts|ubc-mtsg|mts-g|U of British Columbia MTS-g:\
        :cm=NIM call\subcg-mts:\
        :tc=nimd:


6. Edit /etc/x25hosts.  This step is optional.  The X.29 callin server uses
   the information in this file to map an X.121 address to host name and
   the nimd needs the same information to do the opposite with the "call"
   command (see above example with 'ubcg-mts').  Add to the hosts file an
   entry for each remote host that the X.121 address is known.  The flags
   before the X.121 address must be either an 'r' (reverse charge), or 's'
   (hi priority), or a 'p' (also hi priority).  The "hi priority" flag is
   specific X.25(1976) DTE's attached to Canada's Datapac network; all other
   sites can ignore this flag.  Some examples:

#
# Datapac hosts
#
68100124                camosun         # Camosun College, Victoria BC
p,92100086              datapacinfo     # Datapac help
r,67200040              ubcg-mts        # UBC MTS system 'G'
#
# US CCITT hosts
#
s,1311060700067         cornell         # Cornell University, Ithaca NY
s,1311061700139         mit-multics     # Mass Institute of Tech


7. Reboot with the new system.  The log file (default /usr/spool/log/nimd_log)
   will contain a record of routine nimd server activity and any serious
   problems.  This file should be periodically truncated.
