RE: port 80 !!?? Running !
Normal users cannot open sockets on ports less than 1024. Apache avoids this problem by starting as root, creating and binding a socket in port 80 and then switching to another user (nobody). As the socket has already been bound by root, nobody can use it. Note the difference: nobody uses the socket, does not bind it to port 80 (which only root can do). What Tomcat cannot do is switch from root to nobody. It either starts as root or as nobody, and stays with that user for all its execution. If it starts as root it can create sockets in port 1024. If it starts as nobody, it cannot, so it has to use port 8080 or similar. Anyway, using mod_jk is quite easy, and there are lots of docs available that explain how to connect Apache and Tomcat. Hope now it is clear enough, Ion -Mensaje original- De: Tevfik Aytekin [mailto:[EMAIL PROTECTED]] Enviado el: martes, 30 de abril de 2002 15:10 Para: Tomcat Users List Asunto: RE: port 80 !!??

Re: port 80 !!?? Running !
Yes , a non root process cannot bind to a port under 80. Apache actually starts one process as root according to ps -U root. the child processes are started as www.

Re: port 80 !!?? Running !
You said you were concerned about mod_jk so you didn`t want to just map tomcat request to port 80 . If you are running under 1.3 , mod_jk is really simple to get up to speed with. I built it on freeBSD with only minor changes to the make file. Linux has binaries of mod_jk.so available. recently I have also got mod_webapp to run quite well under 1.3 and Apache2. If you need assistance , let me know. If your running under windows, I think people are having alot of trouble with connectors. Tevfik Aytekin wrote: Adrian, I do not understand your answer.
