Hi.
I want to start Tomcat 6.0.33 (running on port 80) from the command line of
a non-root user. I have set the setuid flag in the jsvc binary to
"convert" the non-root user to root at the time of execution. Then the
jsvc binary is executed with the "--user tomcat" parameter.
The thing is that the whole setup works and I can successfully start Tomcat
from a non-root user command line if I don't use APR (libtcnative-1).
But then I installed APR and now I can only start Tomcat from root command
line. If I try to start Tomcat from the non-root user command line I get
the exception at the bottom.
Why is this happening? Is this a Tomcat bug? Do I have to setuid another
file besides "jsvc"? Thanks!
