[jitsi-users] Things on my mind


#1

I sent this to the users mailing list earlier, but it did not seem to
get posted. Resending...

Hello, I've been keeping an eye on Jitsi for a while, and I'd like to
say nicely done. It's definitely a program I'd like to use though I'm
waiting for the 2.0 release. I've decided to try out a nightly build.
I'm using v1.1.4275.9988 64-bit on Windows 7, and I am confused about
some things.

Firstly, if you go to Jitsi main window and menu: Tools => Options =>
Accounts tab => click the Add button. I notice that the "Add new
account" window appears briefly, then suddenly vanishes behind the
existing options window. I can move both windows around, but I can't
bring the new account window in front of the options window because it
always slides behind it. I think this is a bug. Can anyone confirm?

Secondly I have some questions about the encryption. In the video
tutorial on your documentation page (3rd video about OTR) I heard that
the lady suggests the OTR fingerprint be verified by using some other
channel like a phone call. Is this true? I always thought the OTR
protocol uses the socialist millionaire authentication to avoid having
to manually compare fingerprints, unlike ZRTP.

I am also confused about all the encryption options. Can I request
that some documentation be made available about the various things
that can be configured? I understand what OTR and ZRTP are supposed to
do, but what the heck are all these options in the ZRTP Ninja window?
What are the "Trusted MitM" and "SAS signature processing" options
supposed to do when (un)ticked? They seem to be unticked by default,
should I enable them? What's the recommended setup for the other
options in the ZRTP ninja window. They're all ticked. Is this okay the
way it is?

Finally, the "chat" part in the security tab (main options window)
does not seem to allow me to generate a fingerprint - the generate
button is greyed out, and there are no accounts available in the
drop-down listbox. I used to be able to generate fingerprints in the
past like this. I have a single google talk account present.

Thanks.

Hey there,

I sent this to the users mailing list earlier, but it did not seem to
get posted. Resending...

We get quite a lot of SPAM on our moderation queue (the one where mail
from unsubscribed users goes on) so sometimes valid messages may go
unnoticed.

Hello, I've been keeping an eye on Jitsi for a while, and I'd like to
say nicely done.

Thank you for your kind words!

It's definitely a program I'd like to use though I'm
waiting for the 2.0 release.

Shouldn't be long now.

I've decided to try out a nightly build.
I'm using v1.1.4275.9988 64-bit on Windows 7, and I am confused about
some things.

Firstly, if you go to Jitsi main window and menu: Tools => Options =>
Accounts tab => click the Add button. I notice that the "Add new
account" window appears briefly, then suddenly vanishes behind the
existing options window. I can move both windows around, but I can't
bring the new account window in front of the options window because it
always slides behind it. I think this is a bug. Can anyone confirm?

I don't see this happening with the latest nightly. Could you please
check with it.

Secondly I have some questions about the encryption. In the video
tutorial on your documentation page (3rd video about OTR) I heard that
the lady suggests the OTR fingerprint be verified by using some other
channel like a phone call. Is this true? I always thought the OTR
protocol uses the socialist millionaire authentication to avoid having
to manually compare fingerprints,

There are a number of things that need fixing with our OTR support.
Fingerprint verification is one of them.

unlike ZRTP.

Note that ZRTP does not require fingerprint verification. You only need
to compare four characters (the SAS) as opposed to a couple of 40
character strings ... so grossly 20 times more efficient.

I am also confused about all the encryption options. Can I request
that some documentation be made available about the various things
that can be configured? I understand what OTR and ZRTP are supposed to
do, but what the heck are all these options in the ZRTP Ninja window?
What are the "Trusted MitM" and "SAS signature processing" options
supposed to do when (un)ticked? They seem to be unticked by default,
should I enable them? What's the recommended setup for the other
options in the ZRTP ninja window. They're all ticked. Is this okay the
way it is?

The text above the ZRTP Ninja button says:

    Jitsi will automatically try to secure all your calls and you will
    both hear and see a notification once a secure connection is
    established. The following button allows ZRTP experts to fine tune
    the way Jitsi behaves during ZRTP negotiation and you don't need to
    modify any of them in order to have secure calls. You should only
    change these settings if you are well aware of the way ZRTP and
    encryption in general work.

This basically means that if you don't know what these options are for,
then you can simply ignore them and let Jitsi do its thing. This would
be the case for 99.99% of the users. Those options are only meant for
security experts who need to make tests or fine-tune Jitsi for better
performance with their infrastructure: ZRTP Ninjas.

Finally, the "chat" part in the security tab (main options window)
does not seem to allow me to generate a fingerprint - the generate
button is greyed out, and there are no accounts available in the
drop-down listbox. I used to be able to generate fingerprints in the
past like this. I have a single google talk account present.

Hmm ... this is interesting. It's normal to have your button greyed out
if you have no accounts in the combo box ... but it is weird not to have
any accounts there. I can't look into it right now but could you please
open a ticket?

Thanks,
Emil

It still happens on jitsi-1.1.4327.10073-x64.exe on my Windows 7.

The thing I wanted to find out is whether any changes are needed in
order to improve compatibility with other non-jitsi clients that use
ZRTP. Note that I haven't tested any calls yet.

Alright. I just tested this in latest nightly, and the box is still
empty. Deleting and re-adding my account has no effect.

Folks,

I am using a recent nightly-build (1.1.4323.10062) with Ubuntu 12.10. I
try to call vía Rynga. When I dial a number, a window appears
indicating it is connecting, but after a while it disconnects with the
message that the remote party did not answer. I dial my own phone
numbers, which never ring, so I know that is not the problem.

I don't know if there is any relation but I have the audio codes
starting with PCMU and then G722, which worked in the distant past.

Can you help?

Thank you

Pablo

I have some more things to add.

- Could you please allow editing offline accounts in the main options
window (accounts tab). Currently the edit button is greyed out for
accounts that are not connected/ticked (Offline). Note: tested only
with google talk (Jabber).

- The video tab in the main options window is unresponsive. It shows
the tab that was displayed last before the video tab was clicked. I
have no webcam attached to my Win7 64bit PC. If I attach a webcam and
restart jitsi, the tab becomes responsive and I can select and view
the webcam video feed. Disconnecting the webcam and restarting jitsi
causes the tab to become unresponsive again.

- The "Add new account" window pops behind the options window on WinXP
32 bit too.

- The dropdown boxes (audio in, audio out, notifications) in the audio
tab (main options window) do not fully display the device names on
Windows 7 64 bit. They seem to be limited to 31 characters - mine gets
displayed as "Speakers (Realtek High Definiti".

- Advanced => Call recording should allow an option to save in OGG
Vorbis format (maybe opus too?).

- I feel like Jitsi is a decent enough IM that it deserves some cooler
sound effects. Could you please replace the SFX with better samples?
No offense, but some of the current sounds are terrible i.e. Incoming
message, Hangup, Incoming call, incoming file, call security, dialing.
The Dialing sound is way too long - speed it up or trim it.

- Is there a way to edit the display nickname? For some reason google
talk decided to use my real name, and I can't find an option to change
it in Jitsi.

Thanks, Emil. I deleted all the codecs except for PCMU and G722 and
then it worked with Rynga. Wouldn't it make sense to make this the
default setting, instead of loading so many codecs, so that a new user
has an easier time of it? Or at least advise on how to set up?

I believe Jitsi is supposed to work with Google Talk, too, right? I did
the same codeds adjustment for the GoogleTalk but it doesn't work. In
fact, it seems to treat contacts set up with Google Talk as chat
connections that await authorization. And the calling option doesn't
appear. How to set up for Google Talk?

Thank you for your help

Pablo

- Could you please allow editing offline accounts in the main options
window (accounts tab). Currently the edit button is greyed out for
accounts that are not connected/ticked (Offline). Note: tested only
with google talk (Jabber).

You can already edit offline accounts. You cannot edit accounts that are
disabled (with the tick unchecked) but I don't see why that would be a
problem.

- The video tab in the main options window is unresponsive. It shows
the tab that was displayed last before the video tab was clicked. I
have no webcam attached to my Win7 64bit PC. If I attach a webcam and
restart jitsi, the tab becomes responsive and I can select and view
the webcam video feed. Disconnecting the webcam and restarting jitsi
causes the tab to become unresponsive again.

This is not what we get so you must be hitting a bug. Could you please
open a ticket and attach logs?

Before you do that however, given that WinXP is EOL now, could you
please check that you reproduce the problem on Win 7?

- The "Add new account" window pops behind the options window on WinXP
32 bit too.

I recently asked someone to open a ticket about this one ... or at least
I wanted to do so ... anyways, could you please open a ticket?

As above, given that WinXP is EOL now, could you please check that you
reproduce the problem on Win 7 before you file the ticket?

- The dropdown boxes (audio in, audio out, notifications) in the audio
tab (main options window) do not fully display the device names on
Windows 7 64 bit. They seem to be limited to 31 characters - mine gets
displayed as "Speakers (Realtek High Definiti".

That's just how Windows returns them through the WMME framework. We
might work on adding dsound support in the following months, which
should also improve latency, in addition to showing the full names, but
we don't know exactly when this will happen.

- Advanced => Call recording should allow an option to save in OGG
Vorbis format (maybe opus too?).

We'd gladly take a contribution for this one but I don't think we'd be
able to work on it in the following months.

- I feel like Jitsi is a decent enough IM that it deserves some cooler

If you have suggestions with appropriate IPR, we'd be more than happy to
have a look.

- Is there a way to edit the display nickname? For some reason google
talk decided to use my real name, and I can't find an option to change
it in Jitsi.

You can do so from within your Gmail account. No way to do this from
within Jitsi (in the case of Gmail, I am not even sure they would allow
us to).

Emil

The unresponsive video tab bug occurs in Linux as well. When I don't
have my webcam plugged in, I see the problem using the latest jitsi
nightly (10077).

Really? How? I'd like to access the account/connection settings window
*before* I enable an account. Currently it's possible to edit the
settings only after you have enabled an account and connected where
the "Edit" button becomes clickable.

It happens on WinXP 32 bit and on Windows 7 64 bit. What steps do you

bug, should I just run jitsi, open the options window and click some
of the tabs including the video?

I am using two XMPP accounts within the Jitsi client. However, it
appears as though I am only allowed one encrypted connection. Is this
the case or should I re-examine my configuration? Perhaps the attached
screenshot will illustrate my point.

Note that account can be offline while being enabled. If you need to
edit offline accounts then just change your presence status to "Offline"
from the contact list and then edit the account.

I don't currently remember exactly why we decided to make disabled
accounts non-modifiable, but chances are that we won't change that part
for 2.0.

That's it. Just run Jitsi, try to open the video configuration, so that
you can see the problem is there (this is when the logs would probably
record exceptions and errors) and then generate the logs.

Emil

There's no such limitation in Jitsi.

I am sorry, I am still not getting it. Two of the accounts have an

Agreed. It used to be better with the Jabber light bulb but then we
moved to (and consequently resized) the XMPP logo so we ended up with
the current situation which I definitely agree does not look good.

Btw, how is/should that number (be) calculated? I have currently three
XMPP-Accounts active, two show no number and the third shows a "2". Does
that thing even serve a purpose at all?

Yana, think you could have a look?

If anyone wants to open a ticket, that might be helpful in case Yana
can't check check it out soon enough.
