I'm searching for an way to give dhcpd process more permissions. I will to add a custom script to dhcdp-hooks. For test I have add to 95-configured this line:
Code:
log $(touch /sdcard/test2 2>&1)
log $(touch /data/misc/dhcp/test2 2>&1)
log $(arp -s 192.168.0.0 54:e6:fc:e9:f8:11 2>&1)
And in logcat I am getting:
Code:
I/log ( 6260): touch: /sdcard/test2: Permission denied
I/log ( 6266): arp: SIOCSARP: Operation not permitted
Only /data/misc/dhcp/test2 works because this folder is owned by dhcp. I will to run arp command (this arguments are only for example) after connecting to a network. Any way to do this without recompiling the complete Android rom, I know that the UID are hard coded in Android code. Another way is getting libcap working on Android, but I can't found any info about this. I have try to put line like this:
Code:
log $(su -c 'arp -s 192.168.0.0 54:e6:fc:e9:f8:11' 2>&1)
But then dhcpd stuck and I can't connect to my network.

-Fails to give root access while running the torpedo as far as I can tell.
(would post to the thread this pertains to but I do not have enough posts to do so apparently)
In addition: this was previously rooted on a older version of the firmware, which one I cannot remember. Current BusyBox is 1.17.1 su is running binary v3.0(11) permissions are -rwxr-xr-x rootshell /system/bin/su
I think this one is definitely needed for this forum as i am seeing more and more users ask how to logcat. So posting this here.
Here's how to use logcat:
There are two main ways to do a logcat, within android, and through adb.
Logcat within android can be done one of two ways, through a Logcat app:
Here are two good examples are either: aLogcat or Catlog
I prefer catlog, because in my opinion it has a little bit nicer UI. Both of these programs can dump their logs to a txt file, which is very useful for debugging. Or, you can do it in terminal emulator (same rules as running through adb(see below))
From Moscow Desire:
On the other hand, using adb to run logcat, in my opinion is much more useful, because you can start using it when android boots (i.e. once the boot animation appears.)
The code for logcat to output to a file is
Code:
adb logcat > name of problem.txt
you can also do
Code:
adb logcat -f name of problem.txt
how I prefer to do it is this way:
Code:
adb logcat -v long > name of problem.txt
with the -v flag & the long argument, it changes output to long style, which means every line of logcat will be on its own line (makes it a little neater, imo)
Note: When outputting to a file, you will see a newline, but nothing printed, this is normal. To stop logcat from writting to a file, you need to press ctrl+c.
Here's where using logcat (via adb makes life really easy)
Lets say you find a problem you're having after looking at a logcat.
For example:
When I was trying to use a different ramdisk, wifi wouldn't work so I got a logcat that's almost 1300 lines long (a lot of stuff happens in the background)
So if you are searching for an error in the logcat file (it's always e/ for error, f/ for fatal. Those are the two main things that will break a system.)

(mind you, that's 29 lines out of 1300ish, just for example)
I then could do the following with logcat:
Code:
adb logcat WifiStateMachine:E *:S -v long > name of problem.txt
and this will only print out any errors associated with WifiStateMachine, and anything which is fatal, which makes it about a million times easier to figure out what's going on!
In WifiStateMachine:E, the :E = to look for Errors, the full list of options is as follows:
V — Verbose (lowest priority)
D — Debug
I — Info (default priority)
W — Warning
E — Error
F — Fatal
S — Silent (highest priority, on which nothing is ever printed)
You can replace the :E with any other letter from above to get more info.
In order to filter out anything other than what you are looking for (in this case, WifiStateMachine) you must put a *:S after your last command (i.e. WifiStateMachine:E ThemeChoose:V ... ... AndroidRuntime:E *:S)

PERSIST DROID SSHD - The persistent lil SSH server
I've modified an SSH server/daemon to install to /system using a .zip, start on boot and even function after the phone has been wiped of it's user data (think anti-theft). Because dropbear is executed with root UID some ROMs even allow for removal su binaries and app while maintaining root shell /filesystem access on device through SSH.

FAQ
I'm going to get this out of the way first thing. Some of it may be painfully obvious but I wanna get as many questions out of the way for those who may be inexperienced, so please bare with me.
Q. What is SSH?
A. SSH is a protocol for establishing secure communications between two computers. You can use it to send remote commands to machines, transfer files, encrypt other forms of communication & tunnel traffic to or from a remote machine. IMHO SSH is probably one of the most versatile protocols out there. If you'd like to learn more just head on over to wikipedia.
Q. I already use an SSH app on my device, what makes your mod so special?
A. That's a good question, so let me break it down... I used to use the SSH apps from the market & they're are great, but all of them lack some important features for me.
F. None of them will run after phone has been wiped of it's user data.
F. A lot of them have some kind of notification or status bar icon.
F. I haven't seen one that allows you to connect to your device when using a mobile data connection.
Q. How does all of this work?
A. It's actually pretty simple. I wrote a bash script that ask the user a series of questions then saves those answers to a file. Another set of scripts starts the server using the answers you specified as parameters. I based it in part on this guide, but my scripts handle all of the dirty work for you.

Released ver. 2.0.9 which adds new features
including:
openssh
wakelock support
connection notification
64bit compatibility
automated private/public key generation
Rom updates (just reflash no config req)
PIE executables
Now using su.d (want init.d copy 60dropbear from su.d to init.d)
Very nice project, I'll after cleaning up my old dropbear this weekend!
I have a few questions:
Does the reverse tunnel set any kind of wakelocks? Or alarms? Or does it rely solely on Android's own network scheduler? Will it reconnect automatically?
How does the wakelock for the sshd work? Is it a full/partial wakelock set on client connect and removed when the client disconnects? Does it work with sftp too?
Thanks!
Friendly reminder:
PLEASE DIRECT QUESTIONS TO Q&A THREAD
The wake lock works by running a script that constantly checks if there is a connection established on port 22 using a while loop and some grep magic. When you disconnect the wakelock is toggled off. I don't know if it is full or partial but it keeps device from slowing to crawl when connected . I did some limited research to get it working.
Code:
#!/system/bin/sh
#Dropbear Wakelock Script by:
#[email protected] ©2015
. /system/etc/sshd.conf
sleep 10
while true; do
sleep 3
if netstat -a | grep 127.0.0.1:22 |grep ESTABLISHED >/dev/null; then
sleep 3
echo "dropbear_wakelock" > /sys/power/wake_lock
elif IP="$(ip route get 8.8.8.8 | awk '{ print $NF; exit }')" &&
netstat -a | grep $IP:22 |grep ESTABLISHED >/dev/null; then
sleep 3
echo "dropbear_wakelock" > /sys/power/wake_lock
elif netstat -a | grep 0.0.0.0:22 |grep LISTEN >/dev/null; then
sleep 3
echo "dropbear_wakelock" > /sys/power/wake_unlock
else
sleep 3
fi
done
it should work with the reverse ssh too and in my test it does
The reverse ssh tunnel uses a loop as well. Whenever the connection gets dropped it will try to re-establish automatically. I have had some minor issues with it but it gets the job done and keeps you connected minus a few rare net conditions... autossh would be better but I can't find a compiled binary for android. I'm working on that tho.
Code:
#!/system/xbin/bash
. /system/etc/sshd.conf
until ssh -N -g -T -K 180 -i "$KEYFILE" -R "$REVPORT":localhost:"$PORT" "$REMUSER"@"$REMSERV" -p "$REMSERVPORT" -y
do
sleep 1; ssh -T -i "$KEYFILE" "$REMUSER"@"$REMSERV" -p "$REMSERVPORT" -y ssh localhost -p "$REVPORT"
done

Friendly reminder:
PLEASE DIRECT QUESTIONS TO Q&A THREAD
The wake lock works by running a script that constantly checks if there is a connection established on port 22 using a while loop and some grep magic. When you disconnect the wakelock is toggled off. I don't know if it is full or partial but it keeps device from slowing to crawl when connected . I did some limited research to get it working.
Code:
#!/system/bin/sh
#Dropbear Wakelock Script by:
#[email protected] ©2015
. /system/etc/sshd.conf
sleep 10
while true; do
sleep 3
if netstat -a | grep 127.0.0.1:22 |grep ESTABLISHED >/dev/null; then
sleep 3
echo "dropbear_wakelock" > /sys/power/wake_lock
elif IP="$(ip route get 8.8.8.8 | awk '{ print $NF; exit }')" &&
netstat -a | grep $IP:22 |grep ESTABLISHED >/dev/null; then
sleep 3
echo "dropbear_wakelock" > /sys/power/wake_lock
elif netstat -a | grep 0.0.0.0:22 |grep LISTEN >/dev/null; then
sleep 3
echo "dropbear_wakelock" > /sys/power/wake_unlock
else
sleep 3
fi
done
it should work with the reverse ssh too and in my test it does

Try on Note 3 Lollipop
I'll try the mod, because I just upgraded my Note 3 to lollipop and had a habit of running my mobile for sftp. Now with lollipop moment it is impossible root access. See if it works.
Thank You.
Edit: I just installed the mod and these are the results, suggestions and problems I found:
Results:
Full access to all folders.
Suggestions:
1.- Although after installing the mod appears "MUST RUN 'pdsshd-toolkit' in terminal after install" Maybe people do not read and in the tutorial you indicate that you have to run "pdsshd-config"
2.- (solution to a small error): When you will run "pdsshd-config" get the following error: "pdsshd-toolkit: Permission denied." This is because the binary file "bash" has the Execute permission. My suggestion is to add to the installation script something like "set_perm (0, 0, 0500," /system /xbin /bash ");" or change permissions manually.
Problems:
1.-The sftp access does not work (which is what I am most interested).
2.-init.d not work. This will cause the kernel of my Note 3 (Civato: http://forum.xda-developers.com/galaxy-note-3/development/rom-civz-flexlollipop-rev1-2-aroma-t2987732)

1.) this is because sftp-server is not compiled with PIE support, just swap /etc/dropbear/data/br.com.bott.droidsshd/files/bin/sftp-server with my attached one.
2.) install SuperSU and move the init script to /system/su.d/10dropbear

Great find! Thanks for providing a sftp binary with PIE support. As you can see I'm not always actively updating this thread. I plan on releasing an update containing the necessary PIExecutables in near future but I can't find one for the dropbear ssh client aka dbclient. If anybody knows of a a client that was compiled with appropriate /support/flags please let me know or uploaded here.
I found a lil info on compiling with PIE support if anyone is interested. I might try it myself... MIGHT...
DISREGARD - Leaving for histroical purposes
If anybody is desperate to run PDSSHD (fully working) there is a way to bypass the requirement for PIEs by replacing /system/bin/linker with a modified one so this whole package will run on lollipop. Be weary though, you're sacrificing security for compatibility and replacing a file required by Android to properly boot. Some user have reported issues. Make a backup of /system/bin/linker first!
DISREGARD
Update:
I compiled a new working version of dbclient (first ver didn't have password access) with PIE support & attached it to this post. It will be included in the next release. PDSSHD is almost fully compatible with lollipop now I just need a PIE binary for inadyn now.
Update 2:
I uploaded a new version of my mod v2.0.6. It should be fully compatible on lollipop and probably marshmallow with the exception of inadyn. I can't figure out how to compile for android yet without ./configure...

here it is, compiled without https support, so it should work with mm, too.

some ideas / requests for further releases:
aroma installer to choose a dropbear or openssh deamon.
gui to configure the deamon.
ssh-copy-id support.
sshfs mount manager
cloud based backup of settings in case of a full wipe.
.
Thanks Sub, you the man! I appreciate you helping with the binaries and supporting other users in this thread. The Aroma installer is probably doable for me, problem is (correct me if I'm wrong) openssh can only use private key authentication since Android doesn't sport /etc/shadow.... I have thought of creating a GUI front end to write to the pseudo sshd.conf but I am no Java/Android app developer so that probably won't be happening unless you or someone you know is willing to tackle it. As for ssh-copy-id, sshfs and cloud based backup I will look further into it
I think I have already found some source to compile sshfs could be wrong tho.

Hi @Geofferey,
I am new to your mod and I like it. I currently use it on my OPO, CM13 and it works quite well (ssh server only, no ddns or reverse).
Only today I was unable to connect to my device. A restart of dropbear solved my problem. So I'd suggest to add a kind of nightly restart. E.g. with cron:
http://stackoverflow.com/questions/16747880/how-to-use-crontab-in-android
In addition to this, I'd suggest a config backup in sdcard. (I use /sdcard/Android/etc for things like that. ) Because I sometimes fully wipe my device (/system, /data, /cache - but NEVER my internal SD ) to really begin from scratch. First thing I could need would be ssh. So on first start after flashing, when there is no sshd.conf, it could search in sd for it and try it with this one if present.
Good work.
Cheers,
Enkidu
Can anyone please tell me, where to place my ssh-pubkey resp. authorized_keys(2) so that I get rid of pw-login!? And what key formats are valid?
Tnx!
I found another problem:
When I reboot my device, dropbear does not work. Means, "ssh mydevice" just hangs. So port seems to be open, but dropbear is not reacting at all.
When I restart dropbear manually, all is fine.
When you reboot your device run pdsshd-toolkit -c and report back what it says.
I need openssh binary for proxy, but it seems that it was compiled without PIE support. Will not run on my Android M 6.0 Device :/ Can you please build a version with PIE support ?
thanks
Thanks for your awesome work! It looks like we also need a build for 64-bit architecture.. I'm running a CM13-NIGHTLY on a Nexus 5X.
Code:
CANNOT LINK EXECUTABLE: "/system/lib/libc++.so" is 32-bit instead of 64-bit
page record for 0x7fa4402010 was not found (block_size=32)
Connection to 10.10.10.12 closed.
I have a Nexus 5X and a S6 as well... I need to recompile for 64bit but I am lazy to attempt ATM. Sorry. I'll update when I get around to it.
So how do I uninstall it? Can I just delete a folder somewhere?
Finally found a way to get this usb 3g modem to work with android x86. Looks like there are significant differences in android kitkat, the other tutorials didn't work for me. Here's what i did in case somebody else finds it useful:
Model: Huawei E1752 HSPA USB Stick
Android x86 4.4.2 on Acer Netbook
Get modem to work under Ubuntu first so you have chat scripts that are known to work with your modem/provider. (If having trouble finding the right AT commands to initialize your modem you can record them under windows. Try free serial port monitor)
Install PPP Widget. It doesn't work, but that gives us usb_modeswitch and pppd to play with.
Install busybox if you don't have it already. Your device should be rooted.
I disabled modem's cdrom mode so that i wouldn't have to modeswitch it with PPP Widget every time (did it from linux)
http://ma.juii.net/blog/disable-usb-mode-switching
Tweak and install pppd/chat scripts for your provider:
/sdcard/pppwidget/ppp/free-chat
Chat script to initiate connection. Change AT commands and dial number (*99#) if yours differ.
Code:
ABORT BUSY
ABORT 'NO CARRIER'
ABORT 'NO ANSWER'
ABORT DELAYED
REPORT CONNECT
TIMEOUT 2
"" AT
OK-AT-OK AT&FE0V1X1&D2&C1S0=0
OK-AT-OK AT
OK-AT-OK ATS0=0
OK-AT-OK AT
OK-AT-OK AT&FE0V1X1&D2&C1S0=0
OK-AT-OK AT
OK ATDT*99#
TIMEOUT 30
CONNECT ''
SAY '\rReport from chat:\r'
/sdcard/pppwidget/ppp/peers/free
pppd config file
Code:
#/etc/ppp/peers/free
# Usage: root>pppd call free
ttyUSB0
3600000
crtscts
connect '/data/data/de.draisberghof.pppwidget/app_bin/chat -v -f /sdcard/pppwidget/ppp/free-chat'
noauth
defaultroute
usehostname
user fooooooo
noipdefault
usepeerdns
idle 0
/sdcard/3gmodem/connect
script to start connection
Code:
#!/system/bin/sh
pppd call free
# use own DNS (OpenDNS)
ndc resolver setifdns ppp0 208.67.222.222 208.67.222.220
ndc resolver setdefaultif ppp0
To connect, open a terminal and type:
Code:
$ su
# cd /sdcard/3gmodem
# ./connect
Now you're connected. browser should work now.
Connection is there but android doesn't know about it, so apps like play store which check connectivity will think you're offline. Install Fake Wifi Connection to deal with those.
Done !
how to get chat script for other modem
Hello, Can I use your chat script with Huawei E3531, and replace only the AT commands?
Do I need busybox?
I have no knowledge of commands, just very basic commands on android terminal.
I am having a really hard time to connect to internet, mainly because Broadcom BCM43142 wifi is not compatible with android 9.0-r2, and older versions.
Thank you
