Two quick questions. Question 1:
When tomcat creates a TCP connection to a remote server (for example, a back-end database) tomcat is acting as the TCP client in that case. Does it use the IP it is listening on as the source IP for its outbound client connection? For example, Server1 has three IPs: 10.0.0.1 (primary), and two additional IPs, 10.0.0.2 and 10.0.0.3. Tomcat is listening on 10.0.0.2. It receives a request that requires it to connect to a database server. When it creates a TCP connection the database server, which IP does it use as the source address? Question 2: Suppose you have two instances of tomcat on the same server. TomcatA is listening on 10.0.0.2 and TomcatB on 10.0.0.3. First, TomcatA establishes a connection to a remote server from its source IP 10.0.0.2, source port 3456. Can TomcatB, which is listening on a different IP, also establish a connection to the remote database server using the same source port 3456, given that the sockets is unique (different source IP)? -Eric Disclaimer : This email and any files transmitted with it are confidential and intended solely for intended recipients.
