How can I tell which ports are blocked

[crazy_gadgets]

HI

So i've got EWA up and running (not tested the streaming part) and can access it all from outside my network.

Unfortunately my Office has kindly decided to block port 7647 so i can't access it from work!
I know I can change the port in GBpvr but the questions is what to change it to. I can't use 80 as i have an IRtrans VFD/IR receiver and it runs a server on port 80 (can't find a way to change it, which would be the easiest thing if anyoine knows how) firefox won't let me access anything on port 21 as Its not a usual web port. So i'm stuck with trying some other ports

Its a bit time consuming to try a port go to work see it doesn't work and go round and round, so what i'd like is a way to be able to see what has been blocked so I can set it up just once!

Anybody any ideas on this, obviously I don't want to be fired for hacking into the system

thanks in advance fior your help

Just a guess...but try 8080. It's most likely not blocked by your company. If somebody else posts...they probably know better though

Alternatively, try 443 which is (I believe) HTTPS and should be open. What I do is use PuTTY to open a SSH tunnel to my machine, then use localhost: port to open the EWA. This way I can leave only one port open but use it for EWA, VNC, etc.

I use 443 for this port as it is usually open anywhere. Hope this helps.

great thanks for that

just tried port 8080 (my routers webadmin is set to that and it works so will switch that around this evening). I'm assuming I need to find a different port to run streaming off although I've not tested it yet on localhost so i don't know anything about it. Must read the wiki later.

I'm not familiar with Putty, will also look into that from what i gather its a way of getting into my machine that then allows me to access it as if I was there.

will google in a minute

thanks for your help

Glad to help. PuTTY is a client app, and you will need an SSH server on your machine - most people go for OpenSSH which can be a bit in depth to get up and running but the documentation is pretty good. For security, I strongly recommend:

Change from the default SSH port; apart from the fact that it will more than likely be blocked by your employer, etc., it is just asking to be probed. Like I say, I use 443 which is (a) very likely to be open and (b) just looks like you are accessing a secure website.

Use PuTTYGen (part of the PuTTY package) to generate yourself a pair of public / private keys; this will be a LOT more secure than just having a password to log in. I check my SSH logs every so often and see it being probed fairly often. Without the private key they don't have a chance and the SSH server just drops 'em. I carry my private key around on a USB drive with PuTTY.

Hope this helps!

Don't use 8080 if you are planning on streaming.....EWA commuinicates with VLC on the server via port 8080.

i use Putty on port 8080 to SSh to my GBPVR server. Then use tunnels for the EWA streaming ports. I've always had streaming problems but i put this down to my low 384k upstream.

Are you saying that because i'm using 8080 to access GBPVR, it could be causing problems with my streaming?

Streaming should work....it is if you try to use the VLC controls that are on the player page (stop, pause, next, etc.) when you click on them they communicate with VLC via prot 8080.

That said......If you are running other things on 8080 they could be impacting your streaming since they would be hitting the VLC web server as well. To my knowlege there is no way to change the port on the VLC web server from 8080.
