I was able to see which app had an open port using standard linux knowledge.
Install terminal emulator or do an adb shell and execute the following:
shell@android:/ $ cat /proc/net/tcp
sl local_address rem_address st tx_queue rx_queue tr tm->when retrnsmt uid timeout inode
0: 0100007F:1C23 00000000:0000 0A 00000000:00000000 00:00000000 00000000 ...

This can be done on Linux: http://blog.mycila.com/2010/06/reverse-usb-tethering-with-android-22.html
You can also use Windows to create a WiFi network (using Connectify) and connect your device to that: http://www.nexusoneforum.net/forum/nexus-one-faq-how-tos/3133-reverse-tether-getting-internet-your-phone.html

OS Monitor lists network connections by app:
OS Monitor and Connection Tracker listing connections (source: Google Play; click image to enlarge)
As you can see, OS Monitor lists up all connections, and lists the corresponding app "owning" this connection along. This should enable you to see all servers your suspicious app connects to. There are other ...

Seeing that you have 2.2, the easiest solution would be to go to Settings -> Wireless & networks -> Tethering & portable hotspots. There you have an option to enable usb tethering (exactly what you asked for) or, even better try out Portable Wi-fi hotspot. That way you will be able to connect to the internet without connecting the phone via usb, and ...

Some large ISPs/cell providers have been known to be assigning reserved IP addresses (i.e. IP address that does not belong to the private addresses) to devices in their network. Many organizations (government and universities) that participated in the early days of the Internet owned very large blocks of IP address that aren't being used, and their IP ...

According to Steve Kondik, this is essentially old code that is leftover from older versions of CyanogenMod:
This was only here for apps that were statically linked against uclibc in old CM versions. It can likely just be removed.
However, he also goes on to note:
Also, this file is NOT written when connecting to a network as /system is readonly. ...

Firefox Mobile supports HTTP proxies, so whilst it's a different rendering engine you should at least be able to get a feel for how your UI performs on a small touchscreen. Here's how to get to the secret config section - http://support.mozilla.com/en-US/questions/758279
The default browser includes proxy support in Gingerbread (although that doesn't help ...

Hey! there is an app for that
Android Usb Port Forwarding

I am a bit confused how to use it, please inform if you get it working perfectly.

While you're on Wifi, have a look in Wi-Fi settings > menu|Advanced.
It looks like it's easier when you're on Wifi than when you're on a celular signal (3 or 2.5g).I've found a blog post here that seems to do what your asking, but you may need to have rooted the phone, or at least be comfotable with editing a few system bits and bobs.

In a word: No.
In order for all applications on the device to have access to a cifs mount, cifs support needs to be compiled into the kernel (or at least available as a loadable module).
I've never seen a device that shipped with such a kernel from the manufacturer. Doesn't mean that they don't exist, I just haven't seen them.
Now, for some devices that ...

A good application to do that is the Samba Filesharing. It shares your sdcard, making it easy to transfer files from/to your phone.
Settings
After installing the application from Google Play, open it and fill a password by touching the password menu. The default username is SDCARD and the default Workgroup is WORKGROUP. You can leave it that way or change ...

You can use rules like this in your custom scripts:
$IPTABLES -A "droidwall-wifi" -m owner --uid-owner 12345 --destination "192.168.1.0/24" -j RETURN
Instead of 12345, you need to specify the UID assigned to the app; you can find that UID in the list of apps in DroidWall.
Remember that UIDs are assigned dynamically, and if the app is removed, the UID ...

You could install XBMC on the linux box then use the XBMC Remote app on your Android device to control the media playing through XBMC.

Yes. On your second PC, set the environment variable ADBHOST to the IP address of the first PC and run the adb server and client. Related steps (more detailed) are here.
Although you're not connecting to a physical device, it is apparently also possible to do so over the network without using USB. Instructions for that are here.

If you combine two apps, this is possible. Of course, root is required on your device to backup app data, as you certainly know.
Now the first app you will need is Titanium Backup. This app not only creates a backup of all apps, app data, and even system data on your SD-Card, contains several useful tools for maintenance, and can schedule its actions -- it ...

Opening ADB on an unsecured connection is a major security risk. On an unrooted phone, it gives access to your entire filesystem. On a rooted phone, it gives access to your entire filesystem with write permissions. The connection isn't encrypted and there is no password or key exchange to access ADB. It's just a bad idea. Beyond that, your carrier may ...

One solution to your problem probably is Reverse Tether:
Other than your hotspot functionality (which lets you use your phones Internet connection with other devices via Wifi), this allows you to use your computers network via USB, as the screenshots imply. Thus your phone gets a (configurable) IP address (pic1: "Desired IP") matching your computers ...

As superuser run:
# netcfg
A list with the interfaces will appear. For example my interface was eth0
# ifconfig eth0 down
# ifconfig eth0 hw ether your:new:mac
# ifconfig eth0 up
Note that not all drivers support this operation, and the Android ifconfig do not support these commands. You will need another ifconfig executable, perhaps that from busybox ...

There is no way to do this natively in the settings of Android, as you've noticed.
However, there is an app on the Android Market called "Wifi Static" that should help you with what you're looking for.

I assume from your posting that resetting the phone fixed the problem (temporarily).
If you want the problem fixed for good, you can help by trying to narrow down the problem further. This will allow you to address the right people with a very specific request of what needs to be fixed. You should:
Try to reproduce the problem. Install the apps you ...

Try the free OS Monitor by eolwral. You can see every physical or logical network interface with associated ipv4/6 and mac addresses as well as total Rx ad Tx. Also has open connections and more, pretty awesome app for free if you ask me.

I'd recommend installing mpd on the linux server and an mpd client on the android device.
The squeezebox server software doesn't play audio directly so you would have to either install a player like SoftSqueeze or SqueezePlay on the server, or use another music application to play the mp3 stream.
You didn't ask about it, but if you want to play music ...

It sounds as though you are just asking for a tethering solution (whereby you share your data connection on your phone with your pc). A stalwart in tethering is the app PDAnet. The free version (which doesn't allow secure connections, but allows most browsing and even WoW connection) can be downloaded from the market and installed on your phone. From there ...

You have to be rooted and you have to have the kernel module for cifs support. if you have froyo, you also will need slow-work.ko kernel module as well.
Once you have those, you can use (shameless plug) Mount Manager, it can handle loading the modules for you automatically and lots of features available for auto mounting when connecting to wifi, and other ...

Most likely because the IP address returned was only valid within the mobile network, i.e. there is a NAT gateway. Even if you tried connecting from another device in the same network, your carrier probably have some routing rules in place to prevent devices from communicating to each other directly.
It would be neat to have a tasker profile or something ...

Android, starting from 4.0, does officially support a form of p2p wifi networking called Wifi Direct. A Wifi Direct-capable device can create an access point which any other Wifi-capable device can access. I don't know about Nexus 7 specifically, but Galaxy Nexus does support Wifi Direct so I'd presume that so is Nexus 7.

I've the exact same issue on a Galaxy Tab P1000 with gingerbread 2.3.3 since about 2-3 weeks.
My current interpretation is that Google has updated its certs (the current one I get is dated 11/7) and the new ones are not trusted by Android anymore making it impossible to use any google account for mail/play store/etc... If this is the case, the only solution ...
