Hi Aaron
I have tested java applet using these RPMs and it turned out that
sometimes it didn't work (using fakewww), however I wasn't able to
find reason for such behaviour. Besides, for me it worked almost all
the time, only few times I have problem with running tests (no
errors, it just stopped working).I guess it may be something with
fakewww as only using it I have noticed such sporadic problems. But,
again, it worked almost all the time after all. Is it that what
blocks us from releasing NDT now or are there any other tasks which
should be completed before it could happen?
Regards
Sebastian

Hi Aaron,
currently not but if needed then I can try to
make some host public so you will have access.
However I'm wondering what exactly will you be
able to verify this way? The problem with applet
not working sometimes is related to which OS,
web browser and java version client uses, so
will hosting page on another system make any
differences? Please correct me if I have not
understood your question right way :)

Hi
again
after further investigation I have
noticed that the problem on linux is
related with bug in these versions of
java (based on discussion
here).
When I installed older version as
suggested there (7u67) I was finally
able to successfully run applet.
Again, running it multiple times
resulted in working ok all the time so
I wasn't able to reproduce bug.
What is current status of releasing
NDT? Are there any things left that
should be done before we can do it?

Hi Aaron
I have tried to reproduce bug with
java applet working randomly (on
widget.html site). What I have
noticed is that on linux systems
(tried on Ubuntu 14.04 and Fedora
20) I wasn't able to successfully
run test using applet and got
warning that plugin was not loaded
properly and when I removed catching
JS exception from script.js file
then it was " Liveconnect call for
Applet ID [id] is not allowed in
this JVM instance" which is java
security issue (unless I have added
site hosting it to exceptions list).
It's odd that using windows and same
security settings I didn't have such
error (java version 8u25, on linux I
have tried with the same version and
7u72 also). However it resulted in
working all the time on windows and
not working all the time on linux,
wasn't able to reproduce it the way
you have mentioned. It would be
helpfull to know what exactly
versions of java they were using and
what system/browser.

Ok,
thanks for clearing that
up Aaron. As for the
init script, if we would
decide to split the
rpms, I believe we would
either have to have the
RPMs conflict, or create
a separate base
rpm(ndt-server-base)
which would contain
scripts, html, fakewww,
the daemon, etc. Then
have two ndt-server rpms
for just the binaries,
depending on the base
package. The daemon
would detect which
version is installed and
it could be manually
configured if both were
present. That would
probably be the simplest
route(aside from having
them conflict), but as
you say, there is no
web10g rpm so thats for
the future.
That’s more the division I was
thinking of: ndt-server-common
(init scripts, fakewww,
flashpolicyd, etc.),
ndt-server-web100 (web100srv),
ndt-server-web10g (web10gsrv).
Allow both -web100 and -web10g
RPMs to be installed, and have
the existing “ndt-server” RPM
become a meta-package that
grabs ndt-server-web100 and
ndt-server-common. Another
option would be to have
“ndt-server” have web100srv,
and have it depend on
ndt-server-common. Upgrades
would then work as expected.

I've noticed
that with the
new web10g
userlands the
RPM will fail
to build,
since
genplot10g is
not mentioned
in the spec
file. I am
assuming this
means that the
rpms being
built for
distribution
will not
contain the
web10g
binaries,
since it
passed on the
build system.
Correct, there is no
dependency for the
RPM on
web10g-userland.
I
am wondering
whether this
is ok for now,
or should we
include the
web10g stuff
in the RPM
distribution.
I think that
both web100
and web10g
binaries can
be packaged
together and
the version
used by the
daemon can be
controlled by
a
configuration
variable.
Another option
is to create a
separate
ndt-server-web10g
RPM for
web10g, since
the web10g
binaries do
require the
latest
userlands as a
dependency.
What is your
opinion on
this?
Since no one is
distributing RPMs
for the web10g
userland (AFAIK),
I’d prefer to leave
well enough alone
for -rc1. If we did
support it, i’d
prefer splitting
RPMs similar to how
you noted, though,
so that folks
without
web10g-userland RPMs
could install just
the web100-dependent
package, and vice
versa. I’m not sure
how the init script
situation would work
though.

One bit of

Hey Sebastian,
The
problem comes
in with flash
blockers,
which are
pretty common,
especially
among network
engineers.
I’ve attached
a screenshot
of what I see
when I go to
the page, and
click “Use
Flash”. It’s
completely
unclear to me
that I need to
hit anything
other than
“Start Test”.
However, if I
click “Start
Test”, it will
bomb out in a
bizarre
fashion,
because I
haven’t
clicked on the
flash applet
below the
buttons to get
around the
flash blocker,
and since I
can’t scroll
the page at
all, I can’t
even see that
there is
something for
me to click. I
just have to
blindly click
in that box
that’s below
the blue page,
and I’m given
no guidance to
do that.
Beyond that,
it’s rather
jarring to
have both
appear in that
page. If we
could shrink
the applet
down so that
it’s a very
small bar, and
specifically
note the
“flash block”
issue in the
text somewhere
(especially if
they click
“Start Test”,
and it bombs
out), that’d
be vastly more
intuitive.
If you
want to try to
see the issue
for yourself,
install a
flash blocker
in Chrome or
FF, and then
navigate to
http://desk179.internet2.edu:7123/
and select
“Use Flash”.

I'm not sure I

this client

So what about

Ah ok.
I’ve got Flash

The new page

of problem
with the

making the

It doesn’t

One
question
regarding your

reason to
change
nobase_ndt_DATA
to ndt_DATA in
HTML5-frontend/Makefile.am?
Without the
nobase
modifier
HTML5-frontend/images
and
HTML5-frontend/fonts
get installed
in /usr/ndt
without the
fonts or
images
subdirectory,
which leads to
missing
resources on
the webpage.
The install
had failed as
is, and as
part of my

removed it,

it when it

Hello

I've
committed

Issue162(https://code.google.com/p/ndt/source/detail?r=1144),

As far as
running the

out of the box
goes, the NDT
server has to
expose the

file, which is
required
for the Flash
client to
allow opening
sockets to the
server.
Unfortunately
the socket
policy does
not go through
HTTP, but a
simple
proprietary
protocol that
uses the TCP
port 843. I am
wondering for
the best way
to handle this
in the NDT

possibly add a
requirement
for a package
like
https://code.google.com/p/flashpolicyd/
and use that
to serve the
file. We could
also consider
bundling some
sort of a
simple server
script(like
this
https://github.com/xantus/mojo-websocket-examples/blob/master/script/flash-policy-server)
that would
serve the
policy file.
Do you

how to resolve
this?
