Hi,
Just to narrow down on things, I wrote a simple Daemon class as
follows
public class MyDaemon implements Daemon
ServerSocket socket;
private String[] args;
public void destroy()
System.out.println("In destroy");
public void init(DaemonContext arg0) throws Exception
// TODO Auto-generated method stub
args = arg0.getArguments();
socket = new ServerSocket();
System.out.println("In init");
public void start() throws Exception
SocketAddress endpoint;
int port = Integer.parseInt(args[0]);
endpoint = new InetSocketAddress(port);
// TODO Auto-generated method stub
try
socket.bind(endpoint);
catch(Exception e)
e.printStackTrace();
System.out.println("Cannot bind on port " + port);
System.out.println("In start");
public void stop() throws Exception
// TODO Auto-generated method stub
System.out.println("In stop");
and I run the same class using jsvc as ./jsvc -debug -verbose -cp
commons-daemon.jar:testj1.jar com.test.MyDaemon 125
I always get a BindException saying Permission denied. What am I
doing wrong. I am running as root and also the port is very much available.
Have herewith attached the jsvc output.
Any help / suggestions would be highly valued.
Thanks,
Srijith.

Hi All,
I am using jsvc to daemonize my java application, which runs on a
Linux box. I get an error java.net.BindException: Permission denied. I get this
only for ports < 1024 and I understand on linux to bind to any ports which are
below 1024, you require root permission. Therefore I am launching my
application as root. However I still am not able to get the privileges
required. My JSVC arguments are as follows.
jsvc.exec -debug -Xdebug -Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8008 -jvm server -user
root -home $JAVA_HOME
-outfile /var/opt/myfile.out -pidfile /var/run/myfile.pid -errfile '&1'
I am launching as root user and also in jsvc arguments I have
specified "-user root", but am at a loss as to why I am still getting this
exception, when I launch my jetty server. When I tried to launch it normally
outside jsvc, it works fine. I have searched on the net, and also came across
this message thread
http://markmail.org/message/3mw6r2dievxvviu3#query:jsvc%20java.net.BindException%3A%20Permission%20denied+page:1+mid:j2w4dpzp4aaypun6+state:results
where it suggested, that some system call had been modified and it worked
thereafter, but did not find the details.
Have run strace, but could not find any errors.
On starting in debug mode, I see the following messages,
10/12/2008 18:55:30 6349 jsvc debug: user changed to 'root'
10/12/2008 18:55:30 6348 jsvc debug: User 'root' validated
and I also don't see any errors.
Any help / suggestions in this regard would be greatly appreciated.
Thanks,
Srijith.
