hmm, I directly connected the unit to my PC now (1000mb/s vs 100 mb/s before) and it's alleviating the problems I was having

I was a bit skeptical of the wall port that I was using before

Essentially, the unit was VERY slow to respond to anything: web, telnet, ssh, lighttd web, even just editing a text file over the network (using either vim or nano) was making it go really slow).  Everything was way slower than I expected and often times things timed out.  File transfers were also very very slow.  So either my router (linksys wrt-54g w/ dd-wrt) or that wall port (which I've had problems w/ before) is messing up.
I was very surprised by this when I learned that the processor was 500 mhz--more than enough to run quickly for what it is doing.

So if you come across those symptoms (super slow file editing over ssh, locking up, not responding, etc... when you think it shouldn't be doing that), trying direct connecting to your pc (or a different ethernet cable).


Anyway

Now that my issues are gone, perhaps I'll write up some instructions tomorrow for the wiki.  It's really not that hard if you've ever done any building programs from source before...
So the instructions will be aimed at those who haven't.

Do I have permissions to create a page if I'm a new user?

Also, if you don't know anything about BackupPC

I prefer it because basically everything visible is done server side
You only have to set up the rsyncd on the host computer and configure files to be backed up, and then the server does all the scheduling, etc... and it can all be managed from one web interface

I'm sure this is a noob question however, i still need to ask it.

after setting up the latest ffp (0.5 beta).
I'm stepping through your install guide, and i get to the perl command and it fails as i don't have perl installed.

perl configure.pl

im guessing i dl http://www.inreto.de/dns323/fun-plug/0. … .8.8-2.tgz

how do I install this, is the command ?
funpkg -i /path/to/perl-5.8.8-2.tgz

is there anything else that perl needs to get running

and thanks for the write up much appreciated.

cheers

heazlewood, you're going to need more than just the perl program
though after you learn how to install that, I'm sure you could learn how to install lighttpd as well

but anyway, I have updated the wiki with instructions on how to install all of the fun_plug packages at once

Yes, the compiling is done in the configure.pl for BackupPC
For other programs, the sequence often looks like:

./configure
make
make install

So if you want to try building a program yourself, you could go through that.  For example, I built the editor called "nano" for my DNS-323 in the beginning when I was having timing out problems (I thought vim was taking up too many resources perhaps)

If you'd like to try building that yourself, here you go:

Download nano from http://www.nano-editor.org/
or easier, on the DNS-323:

cd /ffp/tmp
wget http://www.nano-editor.org/dist/v2.0/nano-2.0.7.tar.gz
tar zxvf nano-2.0.7.tar.gz
cd nano-2.0.7

Have a look at the INSTALL file if you'd like.  It's a typical INSTALL file that comes with a lot programs
Also have a look at all of the configure options:

./configure --help

There are two options we need to specify are the prefix and bindir.  Often times you don't have to set these options, but in this case, the defaults will go to /usr/local and /usr/local/bin respectively.  The problem with these directories is that they're not on the large RAID volume that's been created, and instead are on the OS volume which is very small in size (try running "df" or "df -h" to see the difference), in addition to anything that's saved on the OS volume will be gone on next reboot.  I'm not an expert on this device, but I'm guessing that the OS volume is on some kind of non-volatile flash memory that is then loaded into a ram disk on startup -- someone that really knows, please correct me on this.

We can set the prefix (basically the installation directory) where ever we would like (except where it will be erased on reboot).  The bin directory could go anywhere, but it really needs to be in the $PATH.  $PATH is a global variable that specifies all of the directories where the system looks for programs to run.  For example, when you type "ls" at the command prompt, it looks in the directories specified by the $PATH variable to find a program called "ls" and then runs it.  To see what's in your $PATH variable:

echo $PATH

The result should be something like:

/ffp/sbin:/ffp/bin:/usr/sbin:/sbin:/usr/bin:/bin

So a good directory to install the nano binary (executable) to is /ffp/bin

./configure --prefix=/ffp/usr/ --bindir=/ffp/bin

now to compile and then install:

make
make install

You should now be able type "nano" at the command prompt and bring up the nano editor

hey pwnbot
i know its been a while but i finally got time to install backup pc.
i have done everything except config backupPC.

when i try to navigate to
http://192.168.x.x:8080/cgi-bin/BackupPC_Admin.pl or
http://192.168.x.x:8080/cgi-bin/sample.pl (file does exist)
i get a 403 - Forbidden

when i look at the permisions on the files i see
-rwxrwxrwx 1 root root 3989 Jul  4 09:29 BackupPC_Admin
lrwxrwxrwx 1 root root   14 Jul  4 09:32 BackupPC_Admin.pl -> BackupPC_Admin
-rw-r--r-- 1 root root   26 Jul  5 09:10 BackupPC_admin

have any idea what i might have done wrong?

cheers for your time agan

On the list of files you have given here, what directory is this?
Why is there a file called BackupPC_Admin and one called BackupPC_admin

and where is sample.pl?

I have just gone through the instructions with another DNS-323 that I'm setting up for someone else so I'm fixing a couple of issues in the wiki page, but I did not encounter your problem.

My guess is that you did not do the lighttpd.conf file correctly or that the permissions on the /mnt/HD_a2/www/ directory (or one of the sub directories) are not set correctly

Here is the listing of my /mnt/HD_a2/www directory:

Thanks pwnbot for your replay.

I had made a misstake in downloading the funplug packages and therefore some applications where not installed.
I was not able to download the packages as mentined in the wiki pages for two reasons:
       1. I didn't enter the '.' at the of the line "----- Packages ."
       2. The DNS setting were not filled via the normal web interface "LAN settings". For some reason it was empty and so there
           DNS323 was not able to connect to the internet.

I've installed the ZLib package but didn't tested it already. Installation was successfully and it didin't take that much time.

You have to install the following packages:

             tar zxvf Compress-Raw-Zlib-2.011.tar.gz
             cd Compress-Raw-Zlib-2.011.tar.gz
             perl Makefile.pl
             make
             make install
             cd ..

             tar zxvf IO-Compress-Base-2.011.tar.gz
             perl Makefile.pl
             make
             make install
             cd ..

             tar zxvf IO-Compress-Zlib-2.011.tar.gz
             perl Makefile.pl
             make
             make install
             cd ..

             tar zxvf Compress-Zlib-2.011.tar.gz
             perl Makefile.pl
             make
             make install
             cd ..


My first backup has been completed successfully.

Thanks.


Question.

Does sombody know how to build some security on the CGI interface as everybody on the network has access to this interface.
Is there a way to work with a kind of authentication procedure?

Thanks

Hi all,

thanks so much for all the work everybody does on that subject, this is so helpfull.

My time to share my experience :

Be carefull to UNCOMMENT THE LINE "mod_cgi" in the lighttpd.conf file.
This is why you might get a 403 - forbidden error when you try to connect to sample.pl page.

Thanks for building the directions for BackupPC. Any thoughts on just building a binary install for fonz0.5?  e.g. an idiot proof install

I'm not a UNIX newbie, but it's the first time I've compiled anything in a long time and the first time on the DNS-323.

Do you have any ideas why I would be getting this error with rsync.h?  I'm using a DNS-323 FW 1.05 and fonz0.5 and compiling on the box itself.

I would really like a binary build, but I think that's going to be a fair amount of work that I'll have to put into it.  One of these days, perhaps....


Anyway, to your problem, why are you doing this through distcc?  You're doing the distcc, right?  I don't remember that being in the rsync install.

Have you installed all of the fonz packages from here: http://www.inreto.de/dns323/fun-plug/0.5/packages/ through the instructions that he gives here: http://www.inreto.de/dns323/fun-plug/0.5/README.txt

Also, can you please list the actual commands you're using and also a little more of the output from that first code snippet?


Lastly, you did do what the BackupPC script was suggesting you do, correct?
    cd BackupPC-3.1.0
    ./configure.pl

Though I suspect that won't work until the perl install gets fixed first.
