[myTouch 4G Q&A, Help & Troubleshooting] S0AndS0:
Hey ran across this sometime ago but didn't know an answer till today... but it's complicated...

1st~ it seems to depend on your service provider...

~ On Sprint I have been able to ssh into my device from a PC connected to a completely different wifi network using Putty on Vista home basic.

~ On Sprint I (with some great help from Almazick here at XDA) have also been able to run a LNMP server and connect to the sample web page and dbmin with the above mentioned network set up but with Chrome and Firefox instead of Putty (yeah that might be a duh statement for some but I don't want to lose ya reader, this stuff is cool ;) ) you can find all the steps that that took by following the link in my sig that points to the XDA Guide I maintain and jump to pages (ruffly) 11-13+ and check the easiest ways to host websites off your device. And I'll eventually have a script and section in the main guide made so you all don't have to scroll through pages of our mutterings :)

~ Almazick, the person that I credit for getting me to do all this extensive testing, is not on Sprint and because of this has run into errors when trying to connect over 3G and or 4G. This leads me to believe that the issue is the network that your device is connected to.

~ Currently there are almost no other variables left that could be at fault. Both Almazick and I are using the same software and apps to test on.... but for those that have to know what the last variables to test is; hardware, we've got different devices and different service providers, and different PC's. All others have been eliminated or made identical or have been adjusted for.

2nd~ Root is required and if you want to ssh like us then getting Linux duel booted up will make life way easier for helping in the future.

~ Almazick uses Lil Debi and I'm a fan of Debian Kit, both can be found on the Android market place for free, and there are other options like QEMU and more but for this definitely start with Lil Debi and a 2Gb img file or larger (still working on figuring it out on Debian Kit) and follow the direction on page 11 or 12 for now.

~ or you could try downloading an app for ssh server (not client alone) and muddle your way through other guides on the web... I'll be testing/checking the possibilities for this but am not holding my breath on when that'll be ready ;)

3rd~ accessing things...

~ running 'cd sdcard' and 'ls' was peppy and responsive

~ running programs or apps that use lots of data or memory can be ruff.

~~ Force closures happen when out of memory. So freeze or force close or uninstall apps that aren't needed if things like that start happening.

~~ things that use lots of data and or memory also cause much drain on the battery and if excessive wile plugged in can cause heat issues. So use a heatsink from an old computer and a fan and maybe pull the battery too and you can run a bit longer on the edge of what your device can do

4th~ all this is very "use at your own risk"

~ I haven't fried or bricked a device yet but things have gotten toasty so use some for thought and be careful.

Final notes;

I realize that this is a thread resurrection and not 100% directly related to your specific device. However, I offer a work around that should work for all devices* running root and Linux so we should celebrate and revel in the wonders of Open source and helpful people :D

*running on Sprint or WiFi if on another network then please try it and report the bugs to me on the main guide thread and I'll work with you and try to resolve it
