The /var/log/messages file showed zillions of the following lines being added continously: Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: time from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: daytime from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: time from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: daytime from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: time from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: daytime from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: time from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: daytime from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: time from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: daytime from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: time from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: daytime from 192.168.17.100 Jul 23 11:21:28 <daemon.info> printfix inetd[1743]: time from 192.168.17.100 .... 192.168.17.100 is the machine where I started nmap.
