run the fun_plug on a usb flash drive

I haven't done this myself, but others have. They might be able to provide more detailed instructions.

Here's how it's supposed to work:
- install funplug (0.5) as usual to /mnt/HD_a2/ffp
- manually mount your usb drive and copy the ffp directory
- change/extend the fun_plug script to load required kernel modules and mount the usb disk
- if successful, make it create a /ffp -> /path/to/mounted/usb/ffp symlink instead of /ffp -> /mnt/HD_a2/ffp
- fall back to /ffp -> /mnt/HD_a2/ffp if usb disk couldn't be mounted or ffp directory wasn't found

Can I upgrade fun_plug 0.3 to 0.5 or do I need to uninstall 0.3 and reinstall 0.5?
If I can upgrade, how can I do it? Did not find upgrade instructions at the README.TXT

Tks

Thanks Tester

Now I really just read the 0.5 README (read 0.3 long time ago).

libcrypto.so is part of the openssl package.

I haven't (yet) hacked the openssh package as I did with dropbear. Openssh runs the shell from /etc/passwd, while dropbear always ran /ffp/bin/sh. You can either change your shell in /etc/passwd or relink /bin/sh to /ffp/bin/busybox or /ffp/bin/bash.

PS: Enter 5784468 to unlock that shell.

PPS: Attached is a small start-script to automatically fix /etc/passwd on boot. Copy it to your dns, move it to the /ffp/start directory and make it executable. No need to reboot, just run:

chmod a+x /ffp/start/passwd.sh
/ffp/start/passwd.sh start

Then check /etc/passwd for /ffp/bin/sh instead of /bin/sh in the last column.

Using fonz's outstanding funplug 0.5 with openssh and keep getting "WARNING: Your password has expired. You must change your password now and login again!"  I'm using SSH Secure Shell v3.2.9 on Windoze XP SP2 (but I don't think it's a client issue). DNS-323 is FW 1.04.

I didn't have this problem with dropbear...but it sounds like you hacked dropbear to use /ffp/bin/ssh.  So I installed and successfully ran the passwd.sh you provided in post #184.  Still the same problem. I've changed the password, but the next time I login, same error. I've played with the sshd_config, but no luck.  It looks like ssh V1 supported a construct of "ForcePasswdChange No" (spelling in this email may not be precise), but this version doesn't like that option.

Thanks for any options you all might suggest. I'd hate to go back to 0.3.

YEAHHH  FONZ! 

So for others who encounter a problem logging in as root with SSH under fonz 0.5. Here are the detailed instructions for installing openssh on fonz 0.5.

1. Download openssh and shadow from fonz's 0.5 distribution http://www.inreto.de/dns323/fun-plug/0.5-experimental/

2. funpkg -i the openssh, openssl (for libcrypt), and shadow packages (I don't recall any other dependencies, perhaps others can comment).

3. Add root to the /etc/shadow password file using fonz's "Setting Passwords" instructions at http://www.inreto.de/dns323/fun-plug/0.3/ (attached below). First add root to /etc/shadow, THEN while logged in as root, run passwd to set the root passwd in the /etc/shadow file.

4. 'chage -l root' will show when the password expires (note first field)
       # chage -l root
       Last password change                                    : password must be changed
       Password expires                                        : never
       Password inactive                                       : never
       Account expires                                         : never
       Minimum number of days between password change          : 0
       Maximum number of days between password change          : 99999
       Number of days of warning before password expires       : 7
   

5. 'chage -d 2008-04-04 root' will change the last password change date to something more current

6. 'pwconv' will copy changes from /etc/passwd to /etc/shadow

6. Since store-passwd.sh is NOT included in 0.5 yet, I've attached it below from the 0.3 distribution. Make sure you run store-passwd.sh at the end to save your changes to NVRAM, otherwise you'll get to do all of this again at the next reboot

ADDENDUM:
--------------
http://www.inreto.de/dns323/fun-plug/0.3/  change root password excerpt.
      -- Setting passwords --

      passwd and smbpasswd can be used to change passwords on the command
      line. To make password changes permanent (i.e. survive reboots), the
      changed password files must be written to flash memory. A script is
      included for that purpose. After running passwd or smbpasswd, run:

       store-passwd.sh

      By default, root has no entry in /etc/shadow and passwd will store
      the password in /etc/passwd instead. If you want your root password
      in /etc/shadow, you can manually add an entry before running passwd:

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

      IMPORTANT: Be sure you run the command exactly as shown. Screwing up
      the shadow file can cause serious problems.

convmv

Simple enough. Please try it and let me know if it works as expected. Note that you need perl, too.

/mnt/HD_a2/MP3/Die Ärzte # convmv -f ISO-8859-1 -t utf-8 -r *.*

I forgot to patch the script interpreter, it seems. This should fix it for now:

ln -s /ffp/bin/perl /usr/bin/perl

Thank you fonz for the 0.5-Funplug. At the momentan i am looking at the source-codes in your SVN. Nice work!

I'm wondering, if it would be possible to include mysql into php? You already linked to an example for MySQL-Server (@Wiki:
http://dns323.kood.org/forum/t1737-MySQL-DNS-323.html), but i'd like to use it from PHP

Hi Fonz,

Your work is super! There are already many packages for ffp 0.5. Is it possible that you also make SABnzbd avaible so it is not required to run it via a chrooted debian? THNX!

thanks fonz for the good work,

anyway, I have trouble getting the sshd server (0.5) to run on my CH3SNAS (latest firmware 1.3).

when I telnet in and do a:
> sh /mnt/HD_a2/ffp/start/sshd.sh start

it says:

/ffp/bin/ssh-keygen: can't resolve symbol 'program_invocation_short_name'
/ffp/bin/ssh-keygen: can't resolve symbol 'program_invocation_short_name'
/ffp/bin/ssh-keygen: can't resolve symbol 'program_invocation_short_name'
Starting /ffp/sbin/sshd
/ffp/sbin/sshd: can't resolve symbol 'program_invocation_short_name'

Am i missing something? It worked correctly with dropbear under 0.3.
Any advice ?

Hi fonz,

I've just tried to get 0.5 up and running and have copied across the files and re-booted which correctly created the ffp files.

I have telnet'd to the 323 OK but when I try and run any of the start scripts I get a message that permission is denied:


/mnt/HD_a2/ffp/start # ./sshd.sh
/ffp/bin/sh: ./sshd.sh: Permission denied

/mnt/HD_a2/ffp/start # ./mediatomb.sh
/ffp/bin/sh: ./mediatomb.sh: Permission denied

I was already using 0.4 to ssh to the box so have my root password set OK so was (optimistically) hoping the all I needed to do to get ssh connection under 0.5 was to start the sshd

Any ides what I may have done wrong?
