Hi All, I am running JBoss 2.4.6 bundled with Tomcat 4.0.3. Every once in a while, when JBoss/Tomcat is started, I get this as a result of nmap:
[deepak@deepak: deepak] > nmap mephisto Starting nmap V. 2.54BETA31 ( www.insecure.org/nmap/ ) Warning: You are not root -- using TCP pingscan rather than ICMP Interesting ports on mephisto (192.168.1.253): (The 1546 ports scanned but not shown below are in state: closed) Port State Service 22/tcp open ssh 139/tcp open netbios-ssn 515/tcp open printer 8080/tcp open http-proxy 8082/tcp open blackice-alerts 32770/tcp open sometimes-rpc3 32771/tcp open sometimes-rpc5 32772/tcp open sometimes-rpc7 But more often I get just this [deepak@deepak: deepak] > nmap mephisto Starting nmap V. 2.54BETA31 ( www.insecure.org/nmap/ ) Warning: You are not root -- using TCP pingscan rather than ICMP Interesting ports on mephisto (192.168.1.253): (The 1549 ports scanned but not shown below are in state: closed) Port State Service 22/tcp open ssh 139/tcp open netbios-ssn 515/tcp open printer 8080/tcp open http-proxy 8082/tcp open blackice-alerts which seems more resonable. Port 8080 is tomcat, and 8082 is JBoss/JMX. Do you know what the 32770-32772 ports would be for? A search on google was not that helpful. I also used lsof -i tcp:32770[1,2] and it listed process java, run by user jboss, as having these ports open. Here's a brief result of the lsof command. COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME java 270 jboss 7u IPv4 604 TCP *:32770 (LISTEN) java 329 jboss 7u IPv4 604 TCP *:32770 (LISTEN) java 330 jboss 7u IPv4 604 TCP *:32770 (LISTEN) Does anybody know what these ports would be for, and why they are being opened? Setup Summary: JBoss/Tomcat : 2.4.6/4.0.3 (custom deb packages) Kernel/Distro : 2.4.18/Debian Java VM : 1.3.1_03 Sun. (build 1.3.1_03-b03) Startup script: Using Debian's start-stop-daemon Thanks in advance, Sincerely, Deepak. -- ________________________________ Deepak Kumar CombiMatrix Corp.
