RT-N66U

[GoogleCodeExporter]

Hi, I just buyed a RT-N66U router and has optware enabled by default on asus 
stoc firmware 3.0.0.3.108.
1 - I installed from our site minidlna v1.0.24 because on stoc firmware is an 
old version v1.0.21 (I have disabled it), is running great but even if is in 
the init.d folder after router reboot is not starting automaticaly, have to do 
it manualy every time with putty telnet.

2 - I tried to install openssh but I get this error:

admin@RT-N66U:/tmp/mnt/USB-HDD/asusware/etc/init.d# ipkg install openssh

First, you have to do is to change the rights of your folder on disk.

# chown -R admin:admin /media/AiDisk_a1/opt
# chmod -R 764 /media/AiDisk_a1/opt
# chmod 640 /media/AiDisk_a1/opt/etc/openssh

After these actions openssh should be installed.

And about auto start. It work on N56u thanks to the efforts of Andy Padavan. In 
your case, there should be two scripts where you can place the code for 
minidlna, so it could be started automatically.

You device is on broadcom chip. So there should be alternative firmwares by 
Tomato, DD-WRT, or others.

PS: Always read the output of commands you type in the command line.  It has 
all needed information for you to make apps work! :)

I managed to install openssh with the right permission but any password I type 
will not be recognized.
I don't want to use dd-wrt, I just want to minidlna start automaticaly or to 
replace inbuild v1.0.21 with 1.0.24
Where should I type the two scripts?
I need openssh to acces the root of the router if is possible.
If Andy Padavan would have a RT-N66U router I'm sure he will make miracles with 
the stoc garbage firmware.
Thanx for your help

I haven't seen N66U interface, that's why I can't tell you scripts path. =/

But try to do in the terminal and then post here:

# nvram show | grep mount

for openssh you should make keys.

# ssh-keygen -t rsa

Then check if the server is running:

# netstat -tpln

You should see such line:
...
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN
...

If there is no such line, check in processes:

# ps aux | grep sshd

Also uncomment and edit HostKey in /opt/etc/openssh/sshd_config

I created key for open ssh but still not accepting any password

You are creating keys in incorrect path. I wrote you to see sshd_config for the 
correct path. OpenSSH in Optware uses the next path by default: 
/opt/etc/openssh/ssh_host_rsa_key. So you should use it instead of "key" you've 
used.

I can see, there are 2 nvram values for mount and umount scripts path. That's 
good. I think it will be possible to port scripts from N56U for auto-start 
scripts, located on you disk. But it uses some other logic for mounting.

Please, post the output of mount command (when your USB is plugged-in). Just do:

# mount

Then, lets check, that these values really work.
create the script  /opt/bin/opt-mount.sh:

# vi /opt/bin/opt-mount.sh
And add there the following:

#!/bin/sh
logger -t "$0" "Hey, I'm working!"

Then do: 
# chmox +x /opt/bin/opt-mount.sh
# nvram set script_usbmount=opt/bin/opt-mount.sh
# nvram commit

Then unplug your disk and plug it again to USB port. Check syslog in web GUI 
for phrase you added to script. If you can find it, then the half of deal is 
done! =)

I created keys in /opt/etc/openssh/ssh_host_rsa_key but still not recognize

The opt-mount script is working, in syslog I get:

I added /opt/etc/init.d/S98minidlna start in opt-mount.sh right after:
#!/bin/sh
logger -t "$0" "Hey, I'm working!"
but minidlna not starting automaticaly on disk mount or router reboot even if 
in the syslog it appears to start:

Hi, it can't start now, because the file had been invoked. I'll try to port 
starting scripts for you tonight. Then it will start automatically.

And what about the output of "mount" command?..

Sorry, I forget about that

/dev/sda1 on /tmp/mnt/sda1 type ext3 (rw,nodev,noatime,data=ordered)

One more thing, I cannot acces telnet from wan even if I oppened the port 22 
and 23

Original comment by Livi...@gmail.com on 4 Apr 2012 at 4:14

[GoogleCodeExporter]

It seems you can't forward ports to router itself. This rule is in native 
firmware of N56U too.

So, finally =)
First, cd to disk, where your opt directory is located (it seems to be: 
/tmp/mnt/sda1)
Do:
# ls -la 
to be sure that "opt" exists in this location. If it does:
# wget -qc http://dl.dropbox.com/u/44733876/test/autoex_n66u.tar.gz -O- | tar 
-zx

Then:
# nvram set script_usbmount=opt/bin/opt-mount.sh
# nvram set script_usbumount=opt/bin/opt-umount.sh
# nvram commit

Reboot the device and see syslog on errors. I hope it will be clear! =)

I suppose, that openssh doesn't work because opt directory is not mounted to 
/opt.
How you've managed to install openssh without it, that's what interesting... =)

Original comment by d...@soulblader.com on 5 Apr 2012 at 6:19

[GoogleCodeExporter]

Somehow /opt is redirected to /asusware folder
ex:
admin@RT-N66U:/tmp/home/root# cd /opt
admin@RT-N66U:/tmp/mnt/sda1/asusware#

admin@RT-N66U:/tmp/home/root# cd /opt/etc
admin@RT-N66U:/tmp/mnt/sda1/asusware/etc#

I will try a little bit later opt-mount.sh
THX

Original comment by Livi...@gmail.com on 5 Apr 2012 at 6:29

[GoogleCodeExporter]

ok, it can be a symlink then:

try:

# ls -la /
I think there should be smth. like:
/opt -> /tmp/mnt/sda/asusware

If so, I think I should correct these scripts a little...

Not working but it's not such a big deal, maybe asus will release soon a new 
updated firmware, I seen on they ftp site 
ftp://ftp.asus.com.tw/pub/ASUS/wireless/RT-N66U_B1/ that is already 
GPL_RT_N66U_B1_3003112.zip.
Thank you

Ahrrr =(
Where does it fail? Any log records? I suppose, these scripts are being called 
with another parameters. Need to see the line in log: "opt-mount.sh: started 
[.....]"
The key is in values of square brackets...

I added logger -t "$0" "Hey, I'm working!" to opt-mount.sh to see if it's 
working and I attached the entire syslog:

I can see now! Line no 193. It doesn't work because the scripts is invoked 
without parameters at all. It checks - if there are not 2 parameters were 
given, then it exits. I'll change them now! =)

That's great! You are welcome! )
Sorry for my Chinese, but I haven't understood the last sentence - 'but it 
takes just more times to mount the usb hdd.' 
Do you mean the time when the disk becomes accessible has been increased? 
That's fine, because scripts need some time to load applicattions. Furthermore, 
you should check files updating options in /opt/etc/init.d/S98minidlna.
And what about ssh? It still doesn't work?..

Sorry for my japanese too, I guess it's something wrong in the original 
firmware, I made fresh install and after 5-15 reboots the hdd is not mounting 
quickly but it takes 10 minutes more or less and this was before your help. I 
tried with 3 different usb disks formatted every time ext3.
I oppened a ticket with asus support but the only answer was to update the 
firmware to the latest version (I allready have the latest 3.0.0.3.1008), even 
my grandmother knows this answer, asus support is terrible.
Thx for your support russian guys.
I didn't tried ssh anymore, maybe later today, S98minidlna is by default 
enabled 0, do not update.
I can't acces my router from work with telnet because like you said before: 
can't forward ports to router itself. 

Original comment by Livi...@gmail.com on 6 Apr 2012 at 8:18

Yes, you are right, Asus support needs more well educated specialists...
I do not recommend you to use telnet outside your home network for its complete 
insecurity. I'll try to install OpenSSH myself a little bit later today to see 
if there are any special things.. But I'm afraid there is no way to forward 
port to use it from the Internet (only fix it in the firmware)

UP:

Just tried OpenSSH.
You know, I've just installed it using: ipkg install openssh
and it works. The only thing - I've had to clean known-hosts file on my 
desktop, because there were another finger-prints for router ip. What error did 
you get, when you was trying  to connect?..

Try to view in syslog what does it want. =)

The last line seems to be strange - 'killall: /opt/sbin/sshd: no process 
killed'.
It seems that server is not running.

You should start it with: /opt/etc/init.d/S__sshd (replace __ with number - I 
can't remember it now)
You also need to change this script. As far as I remember there is no stop 
function. So your disk wouldn't be unmounted correctly until ssd runs from it.

I have same trouble. After looking to syslog I found strange msg: "Account 
admin has expired".
So then I go to /etc/shadow and increase number of last login. and remove  last 
two zeros.
Then I got   Authentication refused: bad ownership or modes for file 
/tmp/home/root/.ssh/authorized_keys.
And I changed permission to 0700. and all works fine.

sorry for the stupid question. i have sock fw 108 installed. i log in using 
telnet but /opt is missing (and so is ipkg). /opt is a symlink to tmp/opt which 
is not there. what am i doing wrong?

Actualy, is not a stupid question, optware is not enabled by default, plug a 
usb disk than go to usb application and install Download Master, now optware is 
enabled but in a different way, opt folder is replaced by asusware.
Here http://forum.ixbt.com/topic.cgi?id=14:56360-6 is a guide from PeterV how 
to enable  the original optware, is in russian and I don't understand much with 
google translate, maybe someone will translate better for us.
If you want to update minidlna to v1.0.24 better upload this firmware

This is the ASUS way to mount disk ))
There is a mistake in the beginning, I can't say why it is mounts and unmounts 
it for some time. This needs the source code reading =/ 

Original comment by d...@soulblader.com on 12 Apr 2012 at 9:39

Thanks for the guide. I was able to install openssh. Few notes: the usb needs 
to be non-fat32 because you cannot set proper file permissions on the ssh keys 
to satisfy sshd. I use ext2 fs now...
and for the "error: Could not get shadow information for NOUSER" the user above 
was right, you have to edit the shadow file manually to fix it. There is no 
add[user/groups] commands on the asus distro... i wonder if this edit survives 
a reboot... anyways your file should look like this:

admin:$1$TW3WPN4z$c4RPpI.QaCNUKSdXdXkSL/:13064:0:99999:7:::
...

Now im able to login. Regarding WAN access, maybe playing with /etc/sshd_config 
file and ListenAddress can fix this?

Thanks!

Original comment by avi...@gmail.com on 14 Apr 2012 at 1:59

[GoogleCodeExporter]

Sure, you can use only ext2 or ext3 partition for the Optware.
There is adduser package in the Optware repository (ipkg install adduser).
But it will be replaced with values from nvram on reboot.  It can also be 
replaced without reboot in runtime by rc. You can add some custom scripts, 
which will be executed on boot (disk mount), but keep in mind that it is not 
'the complete' solution.
For example:
grep -q ^username /etc/passwd || adduser ....
or you can use sed to fix it with regex.

Or maybe try to install dropbear. It doesn't have all openssh functions, but it 
is smaller. 
One small question /etc/sshd_config - is it the correct path? (I just wondering 
of the directories tree. It seems to be unusual in N66...)

Original comment by d...@soulblader.com on 14 Apr 2012 at 2:59

you are right it is on /opt/etc/openssh/sshd_config
