Annotation of researchv9/ipc/README, revision 1.1.1.1

1.1       root        1: The connection server is made up of a number of intertwined programs.
                      2: These programs are roughly divided into three groups:
                      3: 1) Managers (/usr/ipc/mgrs/*) -- These are non-terminating programs started
                      4:    by /etc/rc.  One group consists of dialers that listen for and place calls on 
                      5:    particular networks (dkmgr, tcpmgr, tpcmgr, udpmgr).  The next group are
                      6:    programs used to configure the different networks (dkhup, kdiload, ipconfig,
                      7:    dkipconfig, routed).  Finally is the service manager (svcmgr) that offers
                      8:    the standard user services such as login and program execution.
                      9: 2) Commands (/usr/ipc/bin/*) -- These programs are run by users to perform
                     10:    network functions such as remote login and remote executions.
                     11: 3) Servers (/usr/ipc/servers/*) -- These are programs started by `svcmgr'
                     12:    when called by a command on some other system (telnetd, Rpush, Rpull).
                     13: These programs have been shipped to all of our systems.
                     14: 
                     15: Connection service programs communicate using streams.  They rendezvous by
                     16: mounting onto files in the directory /cs.  A /cs has been shipped to all our
                     17: systems.  It is protected to be writable only by root and bin.  This ensures
                     18: that unprivileged users may not usurp rendezvous points.  A number of user
                     19: accessable moutn points (tcp.1024-tcp.1124) exist for use by telnet and ftp.
                     20: 
                     21: Configuration files are needed by `svcmgr' to know what services to
                     22: offer and for whom to offer them.  These are the files /usr/ipc/lib/auth,
                     23: /usr/ipc/lib/auth.local, /usr/ipc/lib/serv, and /usr/ipc/lib/serv.local.
                     24: /usr/ipc/lib/auth and /usr/ipc/lib/serv are shipped from bowell and contain
                     25: the base set of services and authentications.  The *.local files should NEVER
                     26: be shipped.  They take precedence over the base set and are used to configure
                     27: system peculiarities.
                     28:
