.SH Name
implogd \- IMP logger process
.SH Syntax
.B /etc/implogd
[
.B \-d

.SH Description
.NXR "implogd program"
.NXR "implog file" "entry format"
.NXA "implogd program" "implog program"
The
.PN implogd
program logs messages from IMP, placing them in the file
.PN /usr/adm/implog .
.PP
Entries in the file are variable length and each log
entry has a fixed length header of the form:
.EX
struct sockstamp {
	short	sin_family;
	u_short	sin_port;
	struct	in_addr sin_addr;
	time_t	sin_time;
	int	sin_len;
};
.EE
.PP
This is followed, possibly, by the message received from the IMP.  
Each time the logging process is started up, it
places a time stamp entry in the file (a header with the
.PN sin_len
field set to 0).
.SH Restrictions
The logging process will catch only those messages from
the IMP 
which are not processed by a protocol module.
Thus the log should contain only
status information such as ``IMP going down'' messages, ``host down''
and other error messages,
and, perhaps, stray NCP messages.
