Abstract
A special syslog daemon on a send node, wherein the send node is connected to a receive node by a one-way data link, the special syslog daemon configured to receive a syslog message from a syslog sender, insert a portion of IP information of the syslog sender in the body of the received syslog message and route the resulting syslog message to the one-way data link so that the resulting syslog message can be sent through the one-way data link to a syslog receiver communicatively coupled to the receive node. The present invention resolves the potential conflict between syslog and one-way data transfer applications that are configured to remove IP information from data prior to its passage through a one-way data link, thereby leading to a further enhancement of network security through their combination.
