dynamic DNS for 3G USB modem raspberry pi

Hi guys

I have a 3G USB modem (ZTE Mf 70) . i want to access a IP camera on a particular port from the pi from anywhere in the world.

I wanted the pi to use the same Ip address everytime on bootup. I thought of using a hostname which would map to the IP address everytime (even if Ip address changes)

I wanted to know if installing a dynamic dns application on the pi, would help to achieve this.

or else, is there any other way of doing this ??

I meant this, http://www.tunnelsup.com/raspberry-pi-phoning-home-using-a-reverse-remote-ssh-tunnel

I am using the motion camera software on port number 3456 on the pi.

Will the camera be accessible with the above method/ tunelling method that you mentioned ??

Yup! That would work. It is the same as what I was suggesting. That guy looked longer at the manual to figure out you need to specify "-N" to indicate to SSH that it doesn't need to do anything but open the port.

You specify "3456" instead of 22....

I'm trying to do exactly the same thing on my Raspberry Pi. I would like to be able to use two ports though, one for video, and one for serial data to communicate with a connected UART device.

Two options: run two ssh tunnels to two ports (but this assumes you have a way of connecting a port to the uart). Or just open up the "ssh" port of your 'pi using the tunnel so that you can ssh back into the pi to for the uart stuff.

Try http://www.noip.com/ they give you a static domain name and update their system when your IP address changes.

Hi Mr. Roger

I tried the following steps below to view the video stream remotely , but not able to. Please help me.

Note: I have rented a server with static IP on aws and referring to the same below.
I have a USB camera connected and motion software running and wvdial running (3g dongle).
From the PI's terminal, typed the following :
ifconfig ppp0 Link encap:Point-to-Point Protocol inet addr:100.106.202.59 P-t-P:10.64.64.64 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:212 errors:0 dropped:0 overruns:0 frame:0 TX packets:224 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:9585 (9.3 KiB) TX bytes:11292 (11.0 KiB)
Then typed in:
sudo autossh -M 65500 -o ServerAliveInterval=20 -L 16090:100.106.202.59:8081 -R 2222:localhost:22 user@server
The pi was now logged into my server.
Next, from the server (logged in via putty) I typed in:
ssh -p 2222 pi@127.0.0.1
And I was able to login to the pi.
Now, I opened up a browser on my windows laptop connected to the internet (different network) and typed in
myserveripaddress:16090
And nothing showed up in the browser.
