Hi there Stackoverflow hackers!
I have a very minor case of serious problem, or misunderstanding between me, and the C syslog() function.
The code compiles just fine, and I can see its doing its "dummy job" (pinging 8.8.8.8), but the defined log just does not append. I am completly puzzled by this, and have no idea what could be wrong. Already SMAO (Searched My Ass Off - trying to popularize that) but just can't get it working properly.
Code here:
#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <errno.h>
#include <unistd.h>
#include <syslog.h>
#include <string.h>
// Application settings # TODO: import these from a .ini file
#define WORKDIR "/var/run/management"
#define LOGDIR "/var/log/management"
#define LOGFILE "/var/log/management.log"
#define SCRIPTDIR "/var/spool/management"
#define PIDFILE "/var/run/management/daemon.pid"
int main(void) {
printf("Management Daemon\nInitializing...");
pid_t pid, sid;
setlogmask(LOG_UPTO (LOG_NOTICE));
openlog(LOGFILE, LOG_CONS | LOG_PID | LOG_NDELAY, LOG_LOCAL1);
syslog(LOG_NOTICE, "Management Daemon started by User %d", getuid());
closelog();
printf("Done.\nForking...\n");
pid = fork();
if(pid < 0) {
printf("Fork failed! Exiting...\n");
// TODO: syslog facility
syslog(LOG_EMERG, "Forking failed, exiting.");
closelog();
exit(EXIT_FAILURE);
}
if(pid > 0) {
FILE *pidfile;
pidfile = fopen(PIDFILE, "w");
fprintf(pidfile, "%d\n", pid);
fclose(pidfile);
printf("PID written to %s\nUsing log file %s\nGoing silent...\n", PIDFILE, LOGFILE);
// TODO: syslog facility
openlog(LOGFILE, LOG_CONS | LOG_PID | LOG_NDELAY, LOG_LOCAL1);
syslog(LOG_NOTICE, "Fork returned with valid PID: %d. PID file: %s", pid, PIDFILE);
exit(EXIT_SUCCESS);
}
umask(0);
sid = setsid();
if(sid <
