[Q] Accessing tethered clients from phone/AP - General Questions and Answers

I setup my phone (Gnexus CM10.2.1 Verizon) as wifi access point and have a tablet and rasberry pi connected to it. I can reach the pi from the tablet (ping, ssh, http) using the explicit IP.
I can't, however, reach either the table or the pi from the phone though. Again, trying http and ping off a terminal - using the IP address explicitly.
Should this be possible, or am I missing the point?
FWIW, this is a Galaxy Nexus on CM10.2.1 on Verizon. Have a headless rasberry pi running XBMC, trying to control it with Yatse running on my phone. Best I've been able to do control it from a tablet that's also tethered to the phone. Would like to cut out the middle man.

Running Server over Cellular

Hello everyone,
I am looking into the idea of being able to run an SSH or VNC server on the Windows Mobile platform over cellular (3G). I know for a fact Tmobile can assign a 'route-able' IP address to a phone here in the USA (this has been tested). I can ping this IP address from any computer on the internet (albeit with some substantial latency). Perhaps there is a way to use the Tmobile allowed "pinging your device" to tunnel SSH or VNC traffic.
I would like to figure out a way to reach an SSH or VNC server on my phone using this method. We would need to somehow "open" an inbound port to the phone (this would function like basic port forwarding).
All of this works perfectly over WiFi, of course, but the goal is to get this working over cellular 3G (in particular, Tmobile). I see this as a technical challenge we can overcome as a group.
Does anyone have any ideas on this?
Come on folks, someone must have some ideas on this!
Here's a few links I came across:

[Q] ConnectBot Port Tunneling

I have given up on working out VPN to my home network so I am giving SSH with ConnectBot a go. I can SSH to my home PC through my modem firewall ok now using key passwordless login (safest I understand) but I can't work out port forwarding.
Is it even possible to tunnel certain ports through my home Ubuntu PC using SSH? I want to access local web servers without opening them out on the Internet, for example sanzbd using the nzbair app or my other home media devices, web cams, etc.
I don't feel comfortable opening anything out on the Internet, even SSH makes me nervous although I understand it is fairly secure using key based log combined with a modem firewall and IDS, so I'd like to access my home network but securely.
I understand SSH is the next best option to VPN. But I can't find any guides.
I also have dyndns set up on my modem so (once that propagates I assume) I should be able to reliably SSH to my home PC.
I am very tired, so I'm sorry if this post is absolutely wrong.
I'm 90% certain you'd want to setup squid on your ubuntu box, so you can proxy through. Then connect with connectbot and then set up a portforward to send all port 80 traffic through on whatever port you got squid running on.
I think that should be at least a decent starting place.
Yeah I agree. I have the port tunelling working for sabnzbd now even if it's a bit flakey (drops out sometimes or the port forward can't be created).
So I'll read up on Squid and enable that on my home PC. That may cover a lot of general traffic from my phone too. I imagine a lot of apps use HTTP.

[Q] Problems with MyNet AND Splashtop in home network

Did a few hours of searching, couldn't find something similar enough that helped fix it, so here goes what I've done, and my problem...There are two problems, but I'm thinking they MAY be related....I'm more worried about splashtop though.
PROBLEMS: I cannot get any devices to see the transformer or vice-versa. Using MyNet, I can't see my PS3 or computer, nor can they see it. Also, with splashtop, after installing it all (including the HD app), I can't get them to see each other in my home network. For MyNet, when it's loaded on the transformer, the left-hand side only shows the transformer, and doesn't show any of the other DLNA devices in my household (PS3 up and running, and computer)
They are BOTH connected to my home network. My router (netgear 624v4) sees all the devices as "attached" devices, and all of them can connect to the web and browse, but don't seem to connect to each other. I tried setting up a manual IP address using both the in-network IP and the out of network IP (modem's IP I guess), but nothing.
I don't think this is an issue with ports as I've successfully forwarded them, and as I understand, this shouldn't be an issue in my house anyway. I'm really wanting to remote into the computer, mainly for hulu.com, while at home on the couch, and the MyNet is not too big an issue, but I'm surprised it doesn't work with my PS3.
I have a Netgear 624v4 router, an Actiontec GT701 modem. I have the modem assigning a static IP to the router (192.168.0.2, with the modem being .0.1), and I assigned "reserved" ip's within the router to my computer, PS3, and transformer respectively so I can make sure they get the same IP each time, and the right ports stay forwarded on the right systems.
Really frustrated that even a base application like MyNet isn't seeing the devices and I'm wondering if it's something with the network or router since they can't seem to communicate that way, or maybe something DLNA-wise that I have to do in order to get it all working.
I appreciate any help I can get, and any other tips to try to narrow down the problem. Thank you.

Ok. UPDATE:
Reset my router AND my DSL modem. Opened the ports on BOTH the modem and the router (not necessary for inhouse splashtop, but I thought in case it didnt work, maybe that'd help with remote splashtop access).
Turns out, splashtop ONLY works on the main user account. So I have to try to access it through my wife's account on the computer. One problem solved. TF also finding the computer for MyNet but not PS3 yet. Gonna open the ports for the PS3 (just in case), but I have a feeling that's not the issue.

Cannot connect to desktop, "no route to host"

I am trying to SSH from my Asus Transformer Prime to my Linux desktop using ConnectBot, but get "no route to host".
WiFi on the TFP (192.169.11.5) works fine. I can ping my router 192.169.11.1, but cannot reach my desktop 192.168.11.4. The desktop has sshd running, port 22 is open. Traceroute from the desktop to the TFP fails, Destination unreachable. SSH works to external sites fine from both the TFP & desktop
Sorry, this is probably a really basic networking issue, but I am lost... is there useful diagnostic info I can post? Anyone care to whack me over the head with a cluestick?

making a Chromecast-clone with Rasberry Pi

I am a complete newbie and I have just purchased with Rasberry Pi and want to make a cool wireless appliance/phone app project out of it that behaves a bit like Chromecast.
It's important to make it as simple to configure as possible upon initial set up with Wi-Fi Network ID and password in Raspberry Pi. I want to hide the command line and GUI's of Rasberry Pi from a non-technical user. As you know, Chromecast does all this in a very intuitive way.
Upon powering up and connecting to a TV, Chromecast makes itself discover-able and configurable to a laptop or Android phone running a Chromecast App. Then a user can configure Chromecast's wi-fi network and password within the App( without a user ever connecting to it via USB or Ethernet cable or typing in a 192.168.1.254 or any URL address, as in configuring Wi-Fi router). It's great to help user to manage the Wi-Fi and password settings..etc while hiding that complexities away from a user.
So this gets me thinking about using the same technique with my experimental Raspberry Pi.
I want to implement the Chromecast's self-broadcast and self-discovery via Wi-Fi and App with the experimental project and thus save a user the hassle of connecting to Raspberry Pi to USB or Ethernet cable in order to configure its Wi-Fi settings, but instead through a custom App.
The only problem I have is: How does Chromecast broadcast itself onto the local network? what protocol does it use to make it self-discoverable to other local network portable devices like Android phone running the Chromecast App?
What book do you recommend to help a complete beginner like myself?
I have no clue at all searching all over Google.
Please help if you know any idea. Thanks!
