Subject Constant requests by service Geronimo / aspentec-lm on port 6142
Date Tue, 24 Jun 2014 08:46:21 GMT
I have two servers. One of them is sending requests to the other on a second
basis (if not even more frequent) and I do not know why!

I have used "snoop" and identified following (on the server sending the
requests):

    # snoop udp
    Using device /dev/hme (promiscuous mode)
          lin134 -> 237.255.1.2  UDP D=6142 S=6142 LEN=40
          lin134 -> 237.255.1.2  UDP D=6142 S=6142 LEN=40
          lin134 -> 237.255.1.2  UDP D=6142 S=6142 LEN=40

When I go over to the server "lin134" and inspect the process:

    # grep 6142 /etc/services
    aspentec-lm     6142/tcp                        # Aspen Technology
License Manager
    aspentec-lm     6142/udp                        # Aspen Technology
License Manager
    # lsof |grep aspen
    java      18267      root  178u     IPv6           46657338                  
UDP *:aspentec-lm
    # ps -ef |grep 18267
    root      3919   939  0 15:10 pts/1    00:00:00 grep 18267

    /jre/lib/ext -Djava.io.tmpdir=var/temp -jar
/opt/geronimo-tomcat6-javaee5-2.2/
    bin/server.jar --long

The process "geronimo tomcat" obviously has something to do with it, but I
am unsure what.
I have searched google etc. but this seems to be a rare problem. Please help
