Doesn't work with rooted Epic 4G (Samsung Galaxy S) -- old shell version & no 4G interface support

[GoogleCodeExporter]

Droidwall does not work with a rooted Epic 4G (Samsung Galaxy S)

There are several problems:

1) the stock /system/bin/sh shell does not support shell scripting! 
droidwall.sh fails on the first 'if' statement:
# sh droidwall.sh
[: not found
[: not found
[: not found
[: not found
--version: not found

2) droidwall does not generate rules for the 4G WiMax interface ("uwbr0" on 
this phone). A simple solution would be to apply the same rules to this 
interface as to the wifi interface, since sprint plans come with real unlimited 
4G (unlike the "unlimited" 3G that is really capped at 10GB/month). Or 
alternatively, apply the same rules to the 4G interface as to the 3G interface.

You can detect the existence of the WiMax interface when it's not loaded by 
grep'ing one of the following files:
/system/etc/dhcpcd/dhcpcd.conf:interface uwbr0
/system/bin/dhcpcd:uwbr0
/system/app/MobileAP.odex:dhcp.uwbr0.result
/system/etc/enable_uwbr.sh:iptables -t nat -D POSTROUTING -o uwbr0 -j MASQUERADE
/system/etc/initialize_nat.sh:iptables -t nat -D POSTROUTING -o uwbr0 -j 
MASQUERADE
/system/framework/framework.odex: /sys/class/net/uwbr0/statistics/

Works for me!

Thank you for your hard work Rodrigo! I couldn't stand having an Android 
without your awesome app

By the way -- I noticed droidwall itself doesn't show up on the applicatons 
list in droidwall. Is that only the case on my phone? Or is that intentional?

Great that it works now :)

Droid Wall only displays applications that are capable of accessing the 
network, that is why many applications are filtered from the list. See issue 3 
for more details.

found" Any ideas?

samichlaus:

Probably it's because the scripts that install busybox when you root the phone 
don't properly link all of busybox's functions.

-- Do the following as root, in Terminal --

You can fix this by doing the following:
  mount -o=remount,rw -t rfs /dev/block/stl9 /system
  ln -s /system/bin/busybox /system/bin/grep

You should probably fix all the possibly busybox functions, so you don't have 
to worry about it again:

Once you're done, you probably should remount read-only again: either reboot or 
run the following:
  mount -o=remount,ro -t rfs /dev/block/stl9 /system

Busybox is not always located /system/bin/ - on my phone it is on 
/system/xbin/, for example.

I changed Droid Wall to try to find where "grep" is. Could you try the attached 
development version? Thanks
