Remote Debugging again [message #159612]

We have a remote computer in Switzerland and want to remote debug on it from
Germany.

In Eclipse I can enter the Host. What should I enter there? The IP address?
What about the login and password? How would such a Host address look like
in our case? What about the port? Does the firewall need to be configured
for the used port number?

Here's what you do:

1) log in to the computer in Switzerland (let's say it's called
figugegl.somecompany.ch)
2) Start your VM with -Xrunjdwp:....,address=8888, server=y, ...
3) In Germany, point the eclipse debugger at host
figugegl.somecompany.ch, port 8888 (i.e. create a new Remote Application
launch configuration).
4) connect.

Any firewall will have to be configured to allow IP connections on
whichever port you use.

You write figugegl.somecompany.ch

But it is no web server. It is a EJB application server.

And what about the user name and password? How can I connect to a remote
machine without it?

figugegl.somecompany.ch is a domain name, which translates into an IP
address. You could replace it with the IP address of the target host as
well.

connect and login are different things. If the debugger is listening on
a given port, it can be accessed by anyone who knows the IP and port number.

Is this secure? What about hackers?

What damage can somebody incur by connecting to the JPDA debugger? If
the debuggee process is not running with root privileges, I dont see
much danger. In any case, the hole is only open while the debuggee
process is running, and you are not connected to it.

The hacker could terminate the remote vm! This would be very bad in a
