# 01/xx/2003 Ron Fox.. Remove preforking. This makes the general daemon |
| |
# logic simpler (and there were problems maintaining the preforked |
| |
# population). Since the time averaged connection rate is close to zero |
| |
# because lonc's purpose is to maintain near continuous connnections, |
| |
# preforking is not really needed. |

=head1 NAME |
| |
|
| |
lond - "LON Daemon" Server (port "LOND" 5663) |
| |
|
| |
=head1 SYNOPSIS |
| |
|
| |
Usage: B<lond> |
| |
|
| |
Should only be run as user=www. This is a command-line script which |
| |
is invoked by B<loncron>. There is no expectation that a typical user |
| |
will manually start B<lond> from the command-line. (In other words, |
| |
DO NOT START B<lond> YOURSELF.) |
| |
|
| |
=head1 DESCRIPTION |
| |
|
| |
There are two characteristics associated with the running of B<lond>, |
| |
PROCESS MANAGEMENT (starting, stopping, handling child processes) |
| |
and SERVER-SIDE ACTIVITIES (password authentication, user creation, |
| |
subscriptions, etc). These are described in two large |
| |
sections below. |
| |
|
| |
B<PROCESS MANAGEMENT> |
| |
|
| |
Preforker - server who forks first. Runs as a daemon. HUPs. |
| |
Uses IDEA encryption |
| |
|
| |
B<lond> forks off children processes that correspond to the other servers |
| |
in the network. Management of these processes can be done at the |
| |
parent process level or the child process level. |
| |
|
| |
B<logs/lond.log> is the location of log messages. |
| |
|
| |
The process management is now explained in terms of linux shell commands, |
| |
subroutines internal to this code, and signal assignments: |
| |
|
| |
=over 4 |
| |
|
| |
=item * |
| |
|
| |
PID is stored in B<logs/lond.pid> |
| |
|
| |
This is the process id number of the parent B<lond> process. |
| |
|
| |
=item * |
| |
|
| |
SIGTERM and SIGINT |
| |
|
| |
Parent signal assignment: |
| |
$SIG{INT} = $SIG{TERM} = \&HUNTSMAN; |
| |
|
| |
Child signal assignment: |
| |
$SIG{INT} = 'DEFAULT'; (and SIGTERM is DEFAULT also) |
| |
(The child dies and a SIGALRM is sent to parent, awaking parent from slumber |
| |
to restart a new child.) |
| |
|
| |
Command-line invocations: |
| |
B<kill> B<-s> SIGTERM I<PID> |
| |
B<kill> B<-s> SIGINT I<PID> |
| |
|
| |
Subroutine B<HUNTSMAN>: |
| |
This is only invoked for the B<lond> parent I<PID>. |
| |
This kills all the children, and then the parent. |
| |
The B<lonc.pid> file is cleared. |
| |
|
| |
=item * |
| |
|
| |
SIGHUP |
| |
|
| |
Current bug: |
| |
This signal can only be processed the first time |
| |
on the parent process. Subsequent SIGHUP signals |
| |
have no effect. |
| |
|
| |
Parent signal assignment: |
| |
$SIG{HUP} = \&HUPSMAN; |
| |
|
| |
Child signal assignment: |
| |
none (nothing happens) |
| |
|
| |
Command-line invocations: |
| |
B<kill> B<-s> SIGHUP I<PID> |
| |
|
| |
Subroutine B<HUPSMAN>: |
| |
This is only invoked for the B<lond> parent I<PID>, |
| |
This kills all the children, and then the parent. |
| |
The B<lond.pid> file is cleared. |
| |
|
| |
=item * |
| |
|
| |
SIGUSR1 |
| |
|
| |
Parent signal assignment: |
| |
$SIG{USR1} = \&USRMAN; |
| |
|
| |
Child signal assignment: |
| |
$SIG{USR1}= \&logstatus; |
| |
|
| |
Command-line invocations: |
| |
B<kill> B<-s> SIGUSR1 I<PID> |
| |
|
| |
Subroutine B<USRMAN>: |
| |
When invoked for the B<lond> parent I<PID>, |
| |
SIGUSR1 is sent to all the children, and the status of |
| |
each connection is logged. |
| |
|
| |
=item * |
| |
|
| |
SIGCHLD |
| |
|
| |
Parent signal assignment: |
| |
$SIG{CHLD} = \&REAPER; |
| |
|
| |
Child signal assignment: |
| |
none |
| |
|
| |
Command-line invocations: |
| |
B<kill> B<-s> SIGCHLD I<PID> |
| |
|
| |
Subroutine B<REAPER>: |
| |
This is only invoked for the B<lond> parent I<PID>. |
| |
Information pertaining to the child is removed. |
| |
The socket port is cleaned up. |
| |
|
| |

| |
|
| |
