@(#)implogd.8 6.2 (Berkeley) 05/22/86

C 5 implogd - IMP logger process /etc/implogd [ -d ] Implogd is program which logs error messages from the IMP, placing them in the file /usr/adm/implog .

Entries in the file are variable length. Each log entry has a fixed length header of the form:

struct sockstamp {
 short sin_family;
 u_short sin_port;
 struct in_addr sin_addr;
 time_t sin_time;
 int sin_len;
};

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 sin_len field set to 0).

The logging process will catch only those message from the IMP which are not processed by a protocol module, e.g. IP. This implies the log should contain only status information such as ``IMP going down'' messages, ``host down'' and other error messages, and, perhaps, stray NCP messages.
