[Q] Syslog for Android?

I'm trying to start busybox's httpd at boot w/o success. However, I can start it manually post-boot w/o problems. Can I enable a syslog facility so I can see what happens when the bootup script calls it?
Code:
httpd -p 80 -u 80 -h /sdcard/www -c /etc/httpd.conf
I've tried running the process as -u 80 and as -u 0, both work post-boot, not before.

It's Linux - if there is an rc.local you should be able to drop a string in there to make it start.

Not that simple
There is no rc.local, but I inserted
Code:
/sbin/syslogd -O /data/log/syslog
into the beginning of init.rc, but it logs nothing.

Go into applications and turn on debugging mode. Plug your phone into your computer and run 'adb logcat' or something to that effect. You can play around with your phone and watch the log scroll by.
Your gonna need the whole ADB setup. Go to the samsung epic 4G wiki and check the article about getting root and flashing a new kernel. This will have the instructions for getting ADB on your system as well.

I've compiled my own rooted kernel and a new busybox with syslogd to see if I can diagnose why bb's httpd isn't starting at boot. As I mentioned, it starts manually w/o a problem. adb logcat isn't very useful in this particular situation. Thanks for the reply though.

I'm kind of a noob myself, but I recall reading that init.rc isn't really a shell script. It has a special syntax that is parsed by Android init, I'm not sure just throwing shell commands in there is going to work. I'd post a link to the doc but I can't post links yet

Weird, the first 500 lines of init.rc are nothing BUT shell commands.
i.e. chmod 0666 /dev/input/event0
Anyway, further along in init.rc the daemon processes are started up. syntax looks like:
Code:
service playlogo /system/bin/playlogo
user root
oneshot
I've tried setting up my programs (httpd,syslogd) as services, no joy.

sorry to hijack your post.
but i want to know how do you modify the /init.rc,
because when i reboot, the /init.rc will automatic recovery the old verison.
did you check the /init.rc, is it modified, after your phone reboot?

Does logcat not give you the info you want?
You can go here to find out how to redirect stdout and stderr to the logcat as well.

init.rc is part of the root fs, which is compiled into the kernel. So, a custom kernel is required. Search for custom kernel for details.

[Q] Wifi MAC Fix?

Solved: See post #4
Obviously for those with a modded kernel and broken MAC.
If we knew the real MAC address for the specific device, couldn't we set the module's MAC to our real one?
Or just a MAC spoofer? But more like an un-spoofer..

Im looking for the answer as well...
I have been through every oc kernel so far, only stock/insmod seems to keep the mac addy. This might be the best option until a proper solution is found, if anyone has an idea on how to insmod on startup that would be good.
I also tried ipconfig eth0 hw ether, but got an invalid argument.

Can't you setup a script that insmod's and set that up to run on startup?
I'm sure there is somewhere in the ROM where a script can be added for it to run on boot, or at least a boot time Android one...
init.rc perhaps?

Okay i found it... there is a file called /bootcomplete.rc that calls
/system/xbin/busybox run-parts /system/etc/init.d
so, on stock kernel with oc-dz.ko:
Code:
# cd /system/etc/
# mkdir init.d
# cd init.d
# echo insmod /system/lib/modules/oc-dz.ko pll2_l_val=74 > overclock
# chmod 0755 overclock
will load the module at boot. wifi mac is correct

Okay I've been using this for most of the day and just had a hard crash on level 99 of robo defence(F7U13!) Looking into it, it seems this kernel module only seems to step up from 700 straight to 1497! I'm disabling it for now.
Apparently cyanogen is quite a lot faster than the stock Sense, even without overclock. As soon as it hits RC2, I'm gonna give it a shot.

EDIT
Trying from a Terminal I get: "undable to chmod overclock: Read-only file system"
I tryed from ADB and all commands were accepted, file was created and chmod processed, but after reboot the OC module is not loaded
What ROM are your using ??

Obviously you should remount your system partition rw

What ROM are you using ?? Have you changed the Kernel ??

at the time i was using stock.. currently using virtuous from rom manager

I've been strugglin with that command line for days, trying to find a way t make it stick from boot (and not typing it from a console), I finaly made it today via updater script (update.zip).
I also included the stock radio module and the stock kernel (rooted) to the package, so it can serve as a "rescue kit" for other users stuck with the MAC WiFi shizz. I shared it @ devs forum.

Ubuntu 11.04 unity-2d VNC

Hi guys,
I'm really new here, I can't post in this thread: http://forum.xda-developers.com/showthread.php?t=836022
I created a working ubuntu11.04 .img, with unity-2d. I don't know if anybody cares, it was funny to make.
It is just a minimal install with unity-2d and tightvncserver. Really minimal. Firefox, office applications, anything else DOES NOT installed.
However, you can install anything using apt-get install.
I installed wget and nano, because it was needed to configure the vnc. I plan to make a bigger one with all the programs and stuff installed. Maybe tomorrow. Or next week.
How to use: Unzip, rename to ubuntu.img and simply replace the original ubuntu.img with this one. Use root as user/nickname and ubuntu as password, as usual.
Download link to .img:
Download link to the other files needed:
Links tomorrow. "New" .img too.
If you are a mod and you're reading this, please move this post it the thread I linked in the beginning, or anywhere where this post is in its place.
-Sorry for my english.
Please help! Give me additional space by using my referral: http://db.tt/W0knUea
edit1: So, now I've got 10 comments, I don't have to write everything in separate comments. What I've done yet: make some simple script to automatically turn on/off the vncserver (1024x600, tab native res, I found it enough), and get tired of the resource hungriness of unity-2d. I mean it needs about the same CPU power (I guess) as the galaxy tab has, and it needs about 200MB RAM. But this is to run native. The VNC version is far from native, so it's slow as f..., I mean, very slow. Then I looked for a little less resource-hungry desktop environment, and I found lxde. I made an image with that. It's slow too, but much faster than unity-2d. I need to configure it a little more, to be more touch-friendly. And I want to do a few other thing, and write a how to make your own .img file thing. If you want to do it now, here some links, I will write about it sometimes.

I also suggest reading mount, umount and rootstock man pages.

This image works quite well. As with every VNC build, its a bit slow and Unity doesn't help that (even in its nice Unity-2d form), but if you want Ubuntu on your Tab this is a pretty sweet image. Ultra-lightweight, too. Nice work, OP!

Firstly, thankyou for not making 10 spam posts just to get this posted in the Development section, shouldnt take you long to get 10 posts under your belt in this thread then I'll move it into the dev section for you
Good job by the way..

It's writen down here.
The link to the files is in the first post.

Do I write 'bootubuntu' in command line instead of 'bootlinux' or do I have to change the filename of 'bootubuntu' file? I guess first of the two is correct, but it's better to ask than to brick
Oh and is the AndroidSDK really needed? I don't see anything about usage of it in instruction....

Hi!
The SDK is not strictly necessary since you could use a Terminal Emulator to run the necessary commands but using an ADB shell is just bit easier sometimes. That being said, you should install the SDK if you ever want to do much with an Android. It's easy to install and very powerful.
And yes, write bootubuntu instead of bootlinux when prompted. I know what you mean

Allright, I went through it and now got it installed . But I can't see firefox nor any office application... How to access them? Also can't get into terminal to write 'apt-install' there.....

I'll write a howto tonight or next day or I don't know. I need to study to university too. You need adb or android terminal emulator (from the market) to use apt. Short version: when your prompt is "[email protected]:/#" simply do this command: "apt-get install firefox"

Just poked around a little. Now I know (or at least I think I now) what else I have to do.
http://dl.dropbox.com/u/41806444/bootubuntu2
Cleaned up version of bootubuntu. Copy it to /sdcard/ubuntu and simply run it. You need to use the sh command, so type "sh bootubuntu2" in android terminal emulator or adb shell in /sdcard/ubuntu foler.

Oh, sorry I forgot to mention, this script only works with overcome kernel and rom. You shold modify the
mount -o remount,rw -t ext4 /dev/block/stl9 /system
and the
mount -o remount,ro -t ext4 /dev/block/stl9 /system
rows. Enter "mount" to android terminal to see your /system dir type and path.

Synaptic looks like to work, software-center doesn't even start.

To really enjoy full linux distros like this, one should have a swap-enabled kernel. Instead, kernel on the Tab has no swap, and if you dare open some large app, the lack of ram makes it slow and unresponsive.
This is the main problem imho.

Did you try rootkeeper ? and renamkeing superuser.apk ? I plan to try it next time I wipe but just dont want to mess with it now.

Did not try anything since i dont bave good installed yet.

RootKeeper works. Just shutdown QFE and then re-root. Unroot before you start QFE again.

This does not work. Good for Enterprise tries multiple checks to see if you have root. I specifically tried using voodoo ota rootkeeper to unroot then install Good for Enterprise and I still got the out of compliance error resulting in Good wiping the data and locking the app. The only solutions the google searches show to work are to unroot your phone and remove su, etc. At that point, you might as well reflash stock.
It sucks that so many corporate security feams seem to be jumping on the antiroot bandwagon. Also that they opt for Good over, say, Touchdown.
I refuse to change my personal phone back to stock, so I will end up using google calendar sync on my laptol, and my companies OWA access via broweser for email.

OLD

I would just get a cheap phone to use for work and use Google voice to forward all business calls to your primary phone. This seems like the easier softer way

I am going to take a break but I updated the main post. I may have rebooted with su in /system/bin/ and I think GFE randomly checks and on boot it always runs ...

at work they took away my GFE because I was rooted so I cant test this, but here is an Idea...
Create a user on the system
make GFE startup with that user
deny that user access to all the binaries used for root
that could possibly work I think

same issue
. Any luck? I am having the same issue. I removed SU and Busy box, as well renamed su and busybox in /bin and /binx. I was able to get in for about 5 min then it booted. I have no idea what it checks for because I even checked myself.with Root Check Pro and it couldn't find a trace

im about to have the same issue here. any help would be greatly appreciated.
Well since im only signing up for corporate email so they will pay my cell phone bill, i dont ACTUALLY want email on my phone, im sure this will be of no use to anyone but heres what i did
nandroided my phone
Reinstalled my current rom
Removed Root
Installed and synced good
Nandroided the unrooted version with good installed
Nandroided back my rooted rom
Now once every 40 days ill nandroid my unrooted rom, sync goodlink to stay active (they disable you after 45 days of non use) then put back my rooted rom.

if you flash a rom then remove root will GOOD be able to detect the rom or unlocked bootloader? or does it work as long as you are not rooted?

debug
I plan to wait some time and resync/ run my script to hide sqlite3 busybox and su / the su folder and run this:

maybe I can tell what it is doing with this software.

worked for me. I have an unlocked bootloader, all i did was unisntall root in that rom, then nandrioded the rom. Restored my regular rom and all is well.

Huh, so this why my GOOD app quit working. I had a Nexus S 4G and I started to have problems with GOOD booting me. I got a new SGS3 and rooted it, stock rom, had GOOD device changed with my work and they sent me a new pin. Intalled GOOD from Play and I get the Account Disabled message.
Is there any work around for this yet?

i started a thread. This works for now...

How I made my GPS working on A500

I write down how I made my GPS working after I spent hours trying all tips in the hope it can help someone.
What I write should apply to all ROMs since it concerns the GPS subsystem whose source is closed ("I love proprietary code...").
For an A500 (and not A501) try from the shell
Code:
ls /sys/class/gpio/gpio203/*
if you get
No such file or directory
Click to expand...
Click to collapse
then continue reading.
Now you can try from the shell
Code:
getprop ro.dinfo.radio
if you get
Wifi
Click to expand...
Click to collapse
I cannot help while if you get
3G
Click to expand...
Click to collapse
(this should be the answer for A501, I guess) or something else then I can help.
To solve your problem simply add
ro.dinfo.radio=Wifi
Click to expand...
Click to collapse
to /system/build.prop
You can do it as you want for example by the following commands
Code:
su
mount -o remount,rw /system
cp /system/build.prop /system/build.prop.orig
echo ro.dinfo.radio=Wifi >> /system/build.prop
Pay attention that there are two (2) > in the last line.

Details
I now describe how I reached the previous results because this could help also those making ROMs.
In init.picasso.rc there is actually the solution.
If you look at the services you notice that
# Start GPS daemon
service gps-daemon /system/bin/glgps_nvidiaTegra2android -c /system/etc/gps/gpsconfig.xml
class late_start
user root
group root
Click to expand...
Click to collapse
Then (thanks to engineerings at BMC)
Code:
# /system/bin/glgps_nvidiaTegra2android -h
glgps_nvidiaTegra2android [-d] [-c] [config_file] [job_name] [-p pidfile]
-d: It'll be run as a daemon
-c: It'll be run in a console
-h: This help
-s: stick in a tight loop to await attaching by GDB
-p: file name where the pid will be saved, by default it'll be /var/run/glgps_nvidiaTegra2android.pid
gives you some hints on how to use /system/etc/gps/gpsconfig.xml.
In particular at its beginning you find
<hal
acPortName="/dev/ttyHS1"
lBaudRate="115200"
cLogEnabled="false"
acLogDirectory="/data/gps"
ltoFileName="lto.dat"
ctrlPipe="/data/gps/glgpsctrl"
lcsApiSockName="/dev/socket/gps"
gpioNStdbyPath="/sys/class/gpio/gpio203/value"
gpioDelayMs="120"
arp-supl-enable="false"
/>
Click to expand...
Click to collapse
then if you change to
cLogEnabled="true"
Click to expand...
Click to collapse
and restart the gps subsystem you find nice logs in /data/gps.
You can produce logs and test your gps subsystem by issuing commands as
Code:
/system/bin/glgps_nvidiaTegra2android Cold_Starts
which can be used to make a cold start.
From these logs it was easy to suppose that the issue was that /sys/class/gpio/gpio203/value was not present.
Then in init.picasso.rc you find
# WIFI SKU GPS (BCM)
on property:ro.dinfo.radio=Wifi
write /sys/class/gpio/export 203
write /sys/class/gpio/gpio203/value 0
write /sys/class/gpio/gpio203/direction out
# FOR Ericsson GPS
on property:ro.dinfo.radio=3G
chmod 666 /dev/bus/usb/002/049
chown root root /dev/bus/usb/002/049
Click to expand...
Click to collapse
which explains what you should expect in A500 (ro.dinfo.radio=Wifi) and A501 (ro.dinfo.radio=3G).

When I type.... /sys/class/gpio/gpio203/.... I get the following
/sys/class/gpio/gpio203/active_low
/sys/class/gpio/gpio203/direction
/sys/class/gpio/gpio203/edge
Control
runtime_active_time
runtime_status
runtime_suspended_time
wakeup
wakeup_count
/sys/class/gpio/gpio203/subsystem
/sys/class/gpio/gpio203/uevent
/sys/class/gpio/gpio203/value
---------- Post added at 07:29 PM ---------- Previous post was at 07:25 PM ----------
Then when I type getprop. ro.dinfo.radio....... I get radio
How do get this fixed if needed
