Tomcat directory listing? → java.net.BindException: Permission denied:80 Posted on October 21, 2011 by admin Another error message that can be found http://www.jvmhost.com/articles/java-net-bindexception-permisssion-denied-operation-not-permitted in logs when trying to bind to a non-privileged port http://serverfault.com/questions/112795/how-to-run-a-server-on-port-80-as-a-normal-user-on-linux is java.net.BindException: Operation not permitted. On a shared server this is usually avoided by binding application servers to non-privileged ports and proxying from HTTP (80) and HTTPS (443) ports to specific appservers using virtual host configuration directives. Within a VPS your application server like permission denied Tomcat or JBoss usually runs also as unprivileged user. This is the default setup made by JVM Host on request and also a security-wise recommended one. But here you may want and be able to bind to port 80 (this is also technically possible on a shared server if you have a dedicated IP assigned java.net.bindexception permission denied there). If you run Apache as frontend you usually use mod_proxy, mod_proxy_ajp or mod_jk. See more on this in Mapping Apache to Tomcat and other application servers at JVM Host. Otherwise, if you want to bind your application server to e.g. port 80 or 443 by only modifying its configuration file you may get java.net.BindException: Permission denied:80 Why? Because ports below 1024 can be opened only by root. Possible solutions are: You can redirect connections on port 80 to some other port using iptables. Place the line iptables -I PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080 in /etc/rc.local or other file that is run at the end of boot process. Use authbind, for example modify an application server startup script to contain ‘authbind -deep' prefix Install and configure authbind apt-get install authbind touch /etc/authbind/byport/80 chown tomcat:tomcat /etc/authbind/byport/80 chmod 755 /etc/authbind/byport/80 Start your appserver as regular user su - tomcat authbind --deep $JAVA_HOME/bin/java ... authbind --deep appservers/apache-tomcat-6.0.32/bin/startup.s

I am on Ubuntu Linux and want to run a server on port 80, but due to security mechanism of Ubuntu, I get the following error: java.net.BindException: Permission denied:80 I think it should be simple enough to either disable this security mechanism so that port 80 is available to all users or to assign required privileges to the current user to access port 80. linux share|improve this question edited Aug 5 at 14:29 030 2,46521748 asked Nov 10 '08 at 14:31 Deepak Mittal 1,090387 migrated from stackoverflow.com Feb 14 '10 at 20:47 This question came from our site for professional and enthusiast programmers. 2 What is the problem to run the server on another port that is unprivileged? You are thinking about something as harsh as disabling the security mechanism without providing at least a very serious reason for running a server on that port. Is the server hardcoded to bind to port 80? If so, throw it away. –Anonymous Feb 20 '10 at 17:00 Or a Python error message: socket.error: [Errno 13] Permission denied –Kazark Nov 15 '11 at 15:15 5 pos
