Fun with proxies

[Michael Doube-3]

Hi everyone,

I'm helping a collaborator get started with ImageJ and we are totally
stuck getting access to their network. (freshly downloaded ImageJ and Fiji
both affected)

Internet Explorer always asks for proxy username and password and there
are no system-wide proxy settings. Neither entering the same credentials
nor asking to use system proxy settings works.  Could we be missing
something? I have tried setting sytem-wide proxy details, but then Fiji
spews a 407 error and there doesn't seem to be anywhere I can enter
authentication details. This is on a Win 7 laptop.

If you're talking about MTZ, you can set the system-wide proxy settings
and at least in my tests back then, that helped the matter.

Unfortunately, it is a little bit more involved when 407 is encountered:
you have to implement an Authenticator. I did that here:

http://fiji.sc/cgi-bin/gitweb.cgi?p=fiji.git;a=commitdiff;h=f70190e264da6739a6f21d683bf68aa51f4f2985;hb=refs/heads/master

and activated it in the Fiji Updater thusly:

So: in Fiji, a simple Beanshell like this should do the job:

-- snip --
java.net.Authenticator.setDefault(new fiji.updater.GraphicalAuthenticator());
-- snap --

Hope this helps!

P.S.: I am sure that other people have solved this differently, so I would
caution against including this in core IJ1. Even if it is quite hard, some
people do use IJ1 as a library.

Hi Johannes,

It turned out that the laptop was set up to be in WORKGROUP. Giving it a
proper domain allowed it to find the proxy server, and updates run OK.
Also, I can get the sample images now.

Thanks!
