So. My problems with next: I use pulseaudio as a sound server. I check my mic settings by arecord. All ok, but in Skype mic not working. Only silence. But when I tested it with Skype service and look at pavucontrol I saw that mic worked. Please, help!
here is my checklist I look through whenever I have any problems with Skype and pulseaudio:
open alsamixer and make sure the input source and volume settings are correct
open pavucontrol and make sure the Input Devices -> Port dropdown is set to the right value
make sure Skype itself has detected pulseaudio and is using it as a default device.
hope it helps

I have a application I wrote that uses a serial port (hand scanner connected to it) and I need to detect somehow that another user switched so I can close that port and when the new user logs on to the application it wont get 'port in use' error. Any suggestions? My program is in VB.Net but open to any suggestions.
This is a common issue unfortunately.
I find the best thing to do is create a Windows Service to handle all of the comms so that it works independently of any user being logged in. You can use a WCF/Web Service to get data out of the Windows Service.
I hope this helps.
(I would have posted this as a comment instead of an answer if I could)
I have a program on my iPad that makes a direct TCP connection (bypassing the HTTP proxy settings in the Settings menu). I have been tasked to debug this, but I've been unable to find a way to capture the data stream (and the guy who compiles the program is not very responsive).
So... I've been trying to set my wlan to "no encryption at all", booting up Kali, putting the wlan interface into monitoring mode (airmon-ng start wlan0). Then started Wireshark & tried sniffing on both mon0 & wlan0. Neither did really result into anything useful.
That's what I did till now, but I'm out of ideas.
Does anyone know what way I can do it? (preferably even using Windows?)
What I want to get in the end is a pcap file (so I can look at it in Wireshark) of the data traffic. I'm not interested in the packets per se, but in the raw data transfer of the application.
Thanks!
Use another Laptop (Windows or Linux, your choice) with WLAN card in Promiscuous mode, which will sit besides your iPad and capture all the packets on air.
Check this for more details.
What I finally did: I own an Android telephone which could be rooted (and installed "Shark for Root"). So, I enabled a hotspot, connected my iPad to it, and dumped the traffic that way. Weird thing though is that I had to reboot my device to be able to download the pcap file to my computer. It could be read on the device by SharkReader though without reboot.
bitShark is another option, and looks much more nice, but I prefer the simpler interface of Shark for Root.
my problem is :
after set AT+CMGF = 1 ( for Text mode SMS), everything work well until GSM modem reboot
After reboot, AT+CMGF? command return 0 , this means modem need re-config for CMGF parameter.
Please help to save the config value even after reboot.
Thanks so much.
The traditional modem way to store configuration settings is through profiles, controlled with AT command AT&W, see my answer for some details about that command. Now if your particular modem supports more than one profile and if the AT+CMGF mode is included is another question, but at least AT&W is what I would start investigating around.
I want to run a video conferencing server which can handle 10 party video conference calls(each person should see all the others and himself on their softphone or IP-phone). I tried doing this on asterisk10 using confbridge, but my conference room did not stream video.Audio worked fine.
I looked into bigbluebutton but I do not want any webconferencing solution.
I looked into openvcs but cant make it work as I dont seem to understand the working.
So is there any MCU out there I can intergrate with asterisk to handle my requirement.
you can use the mcu media server for video conferencing solution
you can get the application related info here http://www.medooze.com/products/mcu.aspx
Now freeswitch has full featured video conference with MCU. I have tested system with lifesize hardware and browser based phone and sip client. It works fine
I'm bored cause my development server is down and I'm running the command prompt to ping the server indefinitely so that I'll see when they stop timing out and know that I can work again. In the meantime I wanted to make an Air app that will do this for me, so I can have it chirp or alarm or do something when it starts to be able to connect to the server.
So I need to start with having AIR do the ping, does anyone know how to do this? I can't find any help on it. I can't use the HTTPService because whatever it is that is broken (think it's the VPN), our dev web site is still up.
Thanks
Otherwise you can use the NativeProcess class of the AIR 2.0 beta, and use the ping command of your operating system.
You can find informations on how to use it here.
According to the docs, SocketMonitor, descending from ServiceMonitor will check basic availability, but not a true ping. If you want to truly "ping" the server, you would need to use a socket an implement the protocol, This link to the Wikipedia article might help.
The AIR SDK offers some classes (URLMonitor, SocketMonitor) to handle this:
