I. Overview:I received A friend's question in my blog. After phone communication, I learned the approximate situation:. the headquarters has a leased line to partner B. the partner side is not convenient to add a back-to-point route. When the Headquarters accesses the partner, PATC is implemented. now, if you want to connect the branch L2L VPN to the headquarters and PAT to the partner, the traffic from the branch to the partner is routed to the loopb

Java implements dual daemon and Linux daemon for linux server programs I. IntroductionMany of the current server-side programs are developed based on Java. For Socket programs developed for Java, You need to manually restart the server after the server goes online, it is still very troublesome.Most of the solutions are to use other processes to daemon the server
