Hi Chris,
Firstly, let me thank you for your handy work, its the best thing ever. I am involved with security related systems, IP surveillance to be precise, and Snarl powers almost all my notifications by now. I do however, have some issues with the latest v4 beta 5... I cant get it to redirect or subscribe...
1) Redirect works perfectly using the current release v3, but not 4
2) I don't manage to get v4 or v3 subscriptions to work, the transport is correct, the connection is established, but testing fails...
What am I doing wrong? Is there a guide? The redirect is a bug, I'm pretty sure... Please point me in the right direction...

Hi Karel
Can you send me an example of what you're trying to do so I can troubleshoot?

Hi Chris,
I want to generate Snarl events on a machine (Machine A) and then have a remote PC (Machine B) subscribe to events generated by machine A. On Machine A I have setup a transport GNTP on the correct port, and also completed port forwarding. On Machine B I added the address of machine A under subscriptions...
Current Status:
Machine A, status is listening with 1 connection.
Machine B, status connected, but when I press the test link, it fails.
My alternative setup when this didn't work was to push messages to server B, but this would be less ideal since I don't control port forwarding rules on machine B. When I add a forward to machine B, it also doesn't work, but it works if I use Snarl v3 instead of 4 beta5. Tested this on a different set of computers tho.
Please let me know if anything is unclear...

Hi Chris,
I sent you the Teamviewer details... did you receive the message?

Hi Karel
Just to confirm a few things:
- Does this work ok on a LAN?
- Can you try it using SNP 3 rather than GNTP? My implementation of GNTP is still a bit incomplete

Hey Chris, awesome to hear from you.
1) I did try all the protocols. I may have done something wrong somewhere tho, but i doubt it. You should still be able to access those machines on TeamViewer...

A quick check shows Beta 6 isn't working right - I need to look at the code to see what's going on.

Quick update...
I've had a look at the latest code and I remember now that I'd removed subscription support as it was very unstable, especially around handling when a remote machine unexpectedly disconnected.
Sorry about this. I'm adding the functionality back in right now and will get you a version to test ASAP.
Thanks

Further update. V46.90 EXE uploaded here as a zip:
https://fullphat.net/support/snarl/
Key points:
- Now shows subscribed machines in network page
- Can list consumers of a transport in network page
- Subscribing machine will now reset and wait if the machine it's subscribed to disappears
- Made it more obvious in network page that subscriptions are waiting to connect
- Added notifications when a machine subscribes and unsubscribes
- Notifications are now broadcast to subscribers
- Notifications from Snarl itself are not broadcast to subscribers
All this applies to SNP 3 only at the moment; GNTP support will follow.
To test:
1. Install EXE on both machines
2. Create transport on machine A
3. Create subscription to machine A on machine B
4. Run heysnarl on machine A and create a test notification
Thanks

Hi Chris,
subscribe works, great job!
I did however run into a problem, but it may be resolved by parenthesis:
This URL used to work:
notify?app-sig=Office-MD&title=Office - MD event triggered...&text=Event ocurred:2015/10/12 10:40:18, You may view this event by following the relevant URL\n\nNetwork:\nhttp://11.0.0.73:3080/protected/ViewEvent.htm?uuid%3Df4c7f4b1-67fb-45f6-b0f5-b664ca878117\n\nInternet:\nhttp://197.86.211.240:3080/protected/ViewEvent.htm?uuid%3Df4c7f4b1-67fb-45f6-b0f5-b664ca878117&timeout=6&icon=C:\PROGRA~2\COMMON~1\DRACON~1\Snarl\Img\DRTRIG~1.PNG&sound=-1&action=View event using local network,http://11.0.0.73:3080/protected/ViewEvent.htm?uuid%3Df4c7f4b1-67fb-45f6-b0f5-b664ca878117&action=View event using internet,http://197.86.211.240:3080/protected/ViewEvent.htm?uuid%3Df4c7f4b1-67fb-45f6-b0f5-b664ca878117&action=View your Webplatform using local network,http://11.0.0.73:3080&action=View your Webplatform using the internet,http://197.86.211.240:3080
Now I get the heading, but everything past the \n seems to go missing. I also tested using bestest tester, same results. Must I wrap the text somehow?

How are you generating the notification? I just tried using heysnarl and it worked fine...

Hi Chris,
I'm not being specific enough here, apologies!
If you setup a redirect, and then generate that event, it works fine on the sending machine, but not on the receiving machine. I am using bestest-tester.exe to generate events, and the included message causes snarl to crash without a specific error message.

Understood - that'll be me rushing the SNP 3 forwarding - it's likely not escaping things correctly - will take a look tomorrow if I get chance...

Hey Chris,
I did some additional testing, and Snarl doesn't crash ALL the time, but it does it fairly regularly, as in every few minutes.
You should have no problems replicating the issue...

Hi Chris,
I can confirm that \n causes the messages to be truncated still. I did not get Snarl to crash tho, which is good.
You have been pressed a bit, so are you sure you uploaded the right file? ;)

Hey Chris,
You nailed it! YAY!
This one works according to my previous (Admittedly superficial) test case...Now lets see how it does on a production server with real world challenges. Don't worry, the client has been notified were testing ;)
Out of absolute curiosity, what is the advantages of the different transports?
Chris

to snarl-...@googlegroups.com
At last! :)
So, win32 uses the Windows messaging system and is therefore the fastest but also limited to the machine you're running snarl on. SNP and GNTP are network based so will work within and without the machine running snarl (but they're not multi-user*).
SNP is my protocol so it's under my control; GNTP is controlled by the Growl guys hence doesn't support everything snarl can do, but it does have much better app take-up.
SNP 4 is under development. It'll be a lot more lightweight and will support subscribing, notifying and forwarding better. It will also likely require encryption and hashing by default.
GNTP is traditionally bound to port 23053 but it can be changed, although whether the sending app supports that is down to it of course. Snarl 4.0 abstracts the port number for all transports leaving you free to decide what communicates with what, and how.
* Snarl 4.0 does allow multiuser GNTP in a rather clunky way by creating GNTP transports on different ports.

OK, very informative. Thx!
In our environment multiuser isn't immediately critical, so you're off the hook completely with multiuser systems in the foreseeable future. At least from our world ;)
BTW, this is us: http://www.draconian.co.za/ We have officially started using Snarl beginning 2014 at all our sites. I'm pretty dumbstruck why were the first IP surveillance crowd to embrace snarl tho. I can only think that you need more exposure. Please make a nice 'Supports Snarl' banner so we can stick it in our website, software brochure etc.

Hey Chris,
There is an intermittent crash on the subscriber snarl. Just says stopped responding. It looks like a buffer overflow or something, because I replayed all the events and none of them made Snarl crash. I replayed them a couple of times just to be sure. The generating machine is completely stable. In the test/Live setup, it survived about 80 events since testing started 2.5 hours ago. If you want to send me a debug one, I'll test happily enough.

Hey Chris,
So far so good. I have experienced a few crashes in Snarl since, so there is almost certainly an issue somewhere. The notifications associated with the crash all displayed normally on both computers. Apart from this issue, the end client is ecstatic about this function. I am too ;)
I put a watchdog process in place that monitor snarl and will re-launch as required. A second similar test have just been commissioned, so lets see if this is an isolated incident or maybe machine specific. Who knows. Will report back...

Hi Chris,
I have some updates on this issue...
- I still get occasional crashes.
- Under 'Network' I get lots of the same connecting client as in below image.
- On the client I get "Waiting..." and obviously nothing happens anymore because it reached (I guess) the connection limit..

Hi Chris,
The intermittant crashing is stopping us from using subscribe in a production environment. Please take a peek at it when you have some time, THX!
