Subject RE: Tomcat 4.1, Standalone, Port 80, Coyote
Date Mon, 14 Apr 2003 18:30:40 GMT
Well, I knew this had to do with being a linux newb.  There is a file present on the linux
installation of tomcat that is not present in the windows installation.  That file is the
conf/tomcat.conf file.  Apparently, there is a property called TOMCAT_USER which was originally
set to tomcat4, and once changed to root everything worked fine.  Is there no concept of this
file in a windows installation?  I am just trying to understand the difference between tomcat
installed on linux vs. installed on windows.

and do

ps -ef | grep java 

what user does it say the JVM is running as?
This will also let you know if you have a JVM running that you did not you
have running

also to see if something is currently using port 80 try

netstat -an | grep LISTEN

Ok, that makes sense. I see a few replies here about being root to bind an
app to a port < 1024. I understand those are protected ports. So I am
acting as root on this linux server. Meaning I log into the machine as
root, configure tomcat, and try to start it. No luck. What exactly do I
have to do to bind an application to a port? I know that I have configured
tomcat to use port 80, but it is being denied the bind. So can someone
tell me explicity how to perform this bind? This is only a temporary
solution (for demo purposes) so I shouldn't have to worry about security for
now. Later we will configure tomcat to work with apache. Thanks a lot guys.
I am truly the linux newb. -Dan

On unix, only the superuser and other privileged accounts can open
server sockets on ports numbered less than 1024. Windoze doesn't have
this security feature by default. Either run on a >1024 port, run as
super user, for find another alternative (e.g. use apache front-end, as
apache supports better run-as directives).
