Lighttpd has php support?

No.

It's because root has no entry in /etc/shadow. To create that entry, do the following (in telnet). Be careful to enter first the command exactly as shown:

echo "root::0:0:99999:7:::" >>/etc/shadow
passwd

Is it possible to edit the following file to point to the index page used by lighttpd - and therefore avoid having to map ports?

Don't know. I wouldn't.

Thanks fonz - The change appeared to have worked until I rebooted (via the GUI). Prior to the reboot I was able to login as root via SSH and all appeared okay.

It seems, the "root" line is removed from /etc/shadow on reboot. I guess that's another safety measure like the chmod orgy reported by radiusweb. someguy reported that he can change root password with an earlier busybox binary, however, i don't know if that changes passwd or shadow and if it survives reboots.

a work-around that probably works would be to store the "root" line from shadow in a separate file (e.g. in /mnt/HD_a2/fun_plug.d/etc/shadow.root) and then make the fun_plug script append this to /etc/shadow on boot.it's not ideal, though.

Thanks for the updated fun_plug fonz!!! I currently have upgraded my DNS-323 to Firmware 1.03, and formatted the HDD's and they are back in a RAID1 array. Before I put all the files back, I want to work on the 323 a little bit... My telnet is working fine.

What I am trying to do now is get this lightppd thing working, and I have NO IDEA how to proceed.... From what I am reading on the wiki, and what you have in the fun_plug you provided, the setup's are different... I should mention that I know ABSOLUTLY NOTHING about linux and such, so I don't know what the hell I am doing, just trying to do my best from following the steps in the wiki, or the installation readme.

Can you give me a little insight with how to proceed?? Perhaps a tip with how to go about getting the lighttpd working, or a good reference I can use to learn.... I generally pick up on things fairly quickly when it is 'hands on'.

Also, any idea on how I can improve the FTP module, so that anonymous users don't have read access at root? I would also like to be able to have an FTP log, containing times, IP Addresses, files up/downloaded, and any other pertint info I may have overlooked.

Thanks in advance!!

I am in the same spot as you are (were).  I want to install this lighttpd but know nothing about Linux.  I see that you were able to install it. 

So you just take that sample file, remove "sample" and copy it to the root of the DNS 323?  Then reboot?  It seems too easy.  But I don't have telnet access.  Anyone recommend a program to download to do this?  I have no idea where to even begin on this.

See following post by mykroft for the short version :-)

There still seems to be some confusion. "fun_plug" is the name of a shell script (http://en.wikipedia.org/wiki/Shell_script). D-Link's firmware runs this shell script, if it exists, after you turn on your device. There is no "default" or "standard" fun_plug, you can create your own or use one created by others. People create fun_plug scripts to start programs, most notably a telnet server, but also e.g. the lighttpd web server, an NFS server, or SSH/SFTP. The programs you want to run must be installed in addition to the fun_plug script.

Now there are different ways to organize fun_plug script and programs. The beginners faq on the wiki (and many other wiki pages) follow an approach where program files are copied to a directory "lnx_bin/" (on the first volume), with some additional scripts in the root directory (of vol 1). Several ready-to-use programs and guides to compile your own programs are available. Still, you have to create (or copy&paste) your own fun_plug script.

The funplug package discussed in this thread basically works the same, but organizes things a little different. First, next to the "fun_plug" script, there's a "fun_plug.d/" directory (and no "lnx_bin/") with four subdirectories: "bin/" for program files, "etc/" for config files, "log/" for log files, and "start/" for scripts that start programs. The package is a collection of programs that I compiled for the DNS-323 along with a fun_plug script to start them automatically. A telnet server is also included. The current package is "funplug-0.2.tar.gz" and can be downloaded from my website. Install instruction are also on the website. (The lighttpd.conf-sample file is also part of this package and installed to fun_plug.d/etc/). There should be no need to modify the included fun_plug script.

If you're going to try a fun_plug, no matter what approach you follow, I strongly recommend you read the man(ual) pages of the commands  and the documentation of the programs that you want to use. Concerning the shell, the wikipedia article has some links to introductions, man pages are available at www.linuxmanpages.com.

Have fun.

Hi, I'm using your updated fun_plug (funplug-0.2.tar.gz) and it seems to work, well, mostly. I'm pretty sure that I'm the one doing something wrong, but I was hoping that maybe someone in here can help me out. I'm using firmware 1.03 (NAS202B_DLINKEu_DNS323.1.03b41(1.03.0330.2007)), and it works as it should, before installing the fun_plug. So, there is nothing wrong with my equpiment.

I have two problems:

#1 After installing a script for controlling the fanspeed (the one I found here), I can no longer disconnect from the telnet client, and connect again, unless rebooting the device. I can still access the device over the network (via the file explorer, or ftp), but telnet refuses to establish a connection. If I load the script on boot, I obviously cannot connect at all.
#2 After installing the fun_plug, my discs no longer spin down/enter sleep mode. If I remove the fun_plug, reboot, then they will enter sleep mode again.

How can I fix this? I really don't need the telnet connection (if that's what's breaking it), if I can use the fun_plug to automatically load the new fancontrolscript, since that is the only thing that I'm interested in changing (at least at this time). Any input is appreciated.

This is the script I am using as a fancontroller, it's slightly altered, but on the whole the same that FIB posted (see link above).

#!/bin/sh
#
# Kill the old fan controller
kill -9 `pidof fancontrol`
echo "Fancontrol killed. Installing fan_ctrl.sh"
#echo `pidof fancontrol`
#
update_interval=100
T1=105
T2=140
RPM1=1800
RPM2=4000
#
while [ 1 ]
do
  T=`temperature g 0`
  T=${T##*=}
  # Calibrate
  #T=`expr $T - 5`
  # Show temperature in  Celcius
  #echo "Calculating and setting fanspeed ..."
  newRPM=`expr \( \( $T2 \< $T \) \* $RPM2 \) \| \( \( $RPM1 + \( $RPM2 - $RPM1 \) \* \( $T - $T1 \) \/ \( $T2 - $T1 \) \) \& \( $T \>= $T1 \) \)`   
  fanspeed w $newRPM
  #echo `date` "Fahrenheit" $T "Celcius" `expr \( \( $T - 32 \) \* 10 + 9 \) \/ 18` "fanspeed w" $newRPM > /tmp/fan.txt
  #echo "CURRENT:" $T"F" `expr \( \( $T - 32 \) \* 10 + 9 \) \/ 18`"C -- fanspeed:" $newRPM "(written to /tmp/fan.txt)."
  # wait for next cycle
  sleep $update_interval
done

Wild....

follow the link in the 1st post of this thread.  Grab the fun_plug file(s), and look at the readme file.  You ftp 2 files to your box, set the permissions on the fun_plug file to 777 and reboot - it does the rest by install the fun_plug files and auto activating telnet.....

Myk

Thanks Myk, I downloaded the fun_plug file and read the readme file.  I downloaded an ftp program (SmartFTP Client) and have been trying to copy the 2 files but it fails to copy to the root of the first volume.  Do I even need the ftp program?  Can I just copy the files using windows explorer?

Hm... have you actually read the README.txt file? It says "Unpack funplug-0.2.tar.gz" (e.g. WinZip). It contains "fun_plug" and "fun_plug.tar". These are the two files that you have to copy to your device. Windows explorer should work.

Yes, I unpacked the "funplug-0.2.tar.gz" file.  I then tried to copy the "fun_plug" and "fun_plug.tar" files by using the ftp client but it won't do it.  I can copy them by using the windows explorer just fine.  But I noticed you said to "ftp" them which is why I downloaded the ftp client.

Since I can copy using explorer, after copying do I just restart the box then?  Thanks

Now, on problem #2, I was a bit misinformed, it would seem. It was actually the script that prevented the discs from spinning down.

Add this to the start of your script:

PATH=/usr/bin:/bin:/usr/sbin:/sbin

It should then use "sleep" and "expr" from the the ramdisk (D-Link versions) instead of those installed on disk (funplug versions).

fonz...I copied the 2 files over to the root of Volume_1, and rebooted but nothing happened.  It said it would start a "telnet" automatically.  I am obviously not doing something right here.  Also, when I try to telnet to the machine by using Putty, it won't connect.

mykroft wrote:

Yes you can use explorer to copy them over, but you need a ftp program to make the fun_plug file executable so te dns box can run it upon boot up.

I use flashfxp mself.... 

thinking more about it - go ahead and just try explorer, i think the box applies a umask for file permissions and might possibility set them to 755 or 777 I am not sure tho cause I am at work at the moment....

Ah ha, I see now.  I am at work now so I haven't tried it to verify.  But I was looking at the little "how to" guide of the Smart FTP program I downloaded.  And it has a little tutorial of doing things.  I noticed one that was "CHMOD."  This is where you change the read/write/execute properties of the file.  Yes, I did get the SmartFTP program to connect to the box and I can copy using that now (had to change the setting in the D-Link FTP Server to "Read and Write" permissions.

Now to my next question, I know I am supposed to set the checkbox to "Execute" on the "fun_plug" file.  But what about the "fun_plug.tar" directory/files?

I am learning and will get this up and running tomorrow!

actually i did some digging to find out what some of the other utils were that come in this fun_plug archive.....

dropbear is a ssh server - so there ya go

turning off telnet now - since the ssh server asks for a login/pass

Myk

I have managed to save the 2 files mentioned above to my DNS323.  Rebooted it, and can telnet into it now by using Putty.

This is the message I get when trying to run the lighttpd script.

I tried making a file "lighttpd.conf" with a unix text editor with this code as per the lighttpd.conf-sample file.

But I can't save it to the .../etc/ folder.  Whenever I try it says access denied.  Any ideas?  I am surprised I have made it this far.
