Red 5: Fixing NetConnection.Connect.InvalidApp Error

Are you having problem connecting to your Red5 server? Is the error message, NetConnection.Connect.InvalidApp?

This happened to me too. Sadly, there was no available help online -- but there is now. ^^

This error occurs when your Flash application is connecting to a non-Flash-compatible service, like Skype for instance.

Skype opens a local connection at port 80 (the HTTP port). So if your Red5 is ran, it wouldn't actually be able to provide the RTMP service correctly, thus giving the NetConnection.Connect.InvalidApp error message.

What's the solution? Simply close Skype, restart Red5, and viola! Your open source media server is back running!

Connecting Sun Broadband Huawei 1550 USB modem on Ubuntu 10.04

I'm finally trying Mobile Broadband and friends recommends Sun -- because its the cheapest you can have in Philippines.

So before actually buying one, I tried my friend's Sun USB modem which happens to be a Huawei E1550. My Ubuntu 10.04 installation was upgraded from 9.10 via alternate CD (ISO). It had some problems upgrading because I am not connected to the Internet but went to upgrade most of the installations.

Based on my readings, I shouldn't be having any problem running Huawei E1550 on Ubuntu Lucid Lynx (or 10.04) but I am.

I've repeatedly plugged and unplugged the device and kept restarting Ubuntu but nothing.

So I tried my other friend's Sun USB modem (the ZTE one) and Ubuntu recognizes it -- though I still couldn't connect.

I even went to one of Sun's store at SM Megamall's cyberzone just to ask for assistance but all I got was a sarcastic response. The guy said, "You (as in me) need to be techy to run (the modem) on Linux (Ubuntu)".

It was a blunt slap in the face being a programmer and going-4-years of using Ubuntu. Ouch!

I dare say that I am techy alright, just not enough to connect a damn Huawei E1550 on my Lucid Lynx Ubuntu installation.

A day later after a few googling, I bumped into a post saying that I have to install linux-backports-modules-headers-lucid-generic and usb-modeswitch packages -- possibly not installed on my Ubuntu due to problems I had while upgrading. The article was posted on the day I went to Sun store -- odd, eh?

True enough, Ubuntu started recognizing Huawei E1550 after restarting. Still, I couldn't connect.

I still had to change APN from minternet to fbband and one final restart I'm finally connected.

Not to mention, disabling EAP, CHAP, MSCHAP and MSCHAP v2 -- leaving PAP as the only enabled Authentication Method.
