It will ask for username and password.

admin won't work (because it has a non-existent home dir), but any username/password you configured in the web interface should work.
If you set a root password, you can also log in as 'root' (the telnet without password 'logs in as root').

IMPORTANT: Only root can edit the funplug files by default. If you make telnet ask for username and password, but don't set a root password,
you'll lose the ability to edit the funplug files!

I am not sure if it was caused by the fun_plug or the DNS itself, but when I type in "uptime", it shows that my DNS has been running for "13760 days".
Any idea how to fix this problem?

I changed the telnetd.sh file in the start directory. Reboot. And now when I telnet, it says "could not open connection to host". Oh no, what have I done.

FTP still works. lighttpd also still runs as I can see my website but I cannot telnet.

Is there a way to change the telnetd.sh file? I try to overwrite it via FTP but there's an error "no such file or directory". Previously when I want to chmod or rename a file I have to use telnet, FTP doesn't work. But now with telnet down.... what can I do?

Thanks!

Hack it

If you have php running and if you can still put files into the www directory, create 'chmod.php' and surf to it:


Code:
<?php
chmod("/mnt/HD_a2/fun_plug.d/start/telnetd.sh", 0777);
?>
This will make telnetd.sh world-writeable, so you can edit it.

The last resort approach is: remove the disk, put it in another computer and edit telnetd.sh there.

Your problem shows that it might be safer to store a modified passwd file somewhere on disk and copy it to /etc/passwd on boot. And not store stuff to flash.

Offline

OK so how do I activate php? Otherwise I can just wipe the disk clean and restart. Hvn'et really worked much with it yet.

But on another note, even if I do that, what went wrong when I tried to activate passwrod for telnet? I am probably going to try again and may hit the same problem again.

What text editor did you use? What else did you do to the file (e.g. transferred via ftp?)?

Before experimenting or tweaking critical functions, _always_ make sure, you have a way to recover - especially if you dont have a serial console (you could just login on the serial console, and correct the telnetd.sh file). Several approaches come to mind:

- setup alternate root access via ssh
- make critical files world-writeable (so you can edit via samba and/or as non-root user)
- prepare a special web page for recovery actions

I'm sure there are a lot more possibilities.

I used notepad+ for editing. Shd have used something else? Transfered via filezilla.

I will be reformatting my disk to try again. And I do not have serial assess.

Maybe I'll use Scite to edit it and make sure the file is in LF format when I try the next time.

The php hack does not seem to work. Perhaps my php is not activated.

fonz, I am trying to get something like http://www.phpalbum.net/ working but it requires the GD/GD2 component to compile thumbnails automatically.  There are a few other programs like that one for photo albums that need that too.  As for now I am just using JAlbum but was looking for something all in one that is web based with the ability to upload photos away from home.

Another thing is the mySQL issue.  I know this box can't run that but damn, there are so many programs I would like to run but can't due to that limitation.

I've compiled php with gd weeks ago: http://www.inreto.de/dns323/fun-plug/0. … -5.2.3.tgz

I think you can run mysql in a debian chroot. Can you give a few examples?

Hmm, I am using that php file.  I will have to look at it to see why gd isn't running.

These are some of the things that I have been looking at but can't run without mysql.

Does version 0.2 affect performace of the DNS in a negative way? All I'm running is a fan script really.
Before I used to get same performance as a Windows SMB share to my Xbox as I did with my DNS-323. But now I have shitload of framedrops from the DNS. I am able to copy a DVD in 5-10 minutes from the DNS.  I'm nore sure if these problems started after I installed funplug or not.  Anyone know about this?

fonz, any idea why this happens?

--8<--
/mnt/HD_a2/fun_plug.d/start # sh timezone.sh
timezone.sh: line 15: syntax error: "}" unexpected
--8<--

AFAIK it's the original timezone.sh script from fun_plug v0.3

Thanks.

Does this output look normal?
