I'd suggest I'm notreally a noob (though at funplkug I am), but evidently I must be .. after setting up the latest firmware and funplugging it up, I had no problems; telnet worked fine, so I set up the sshd package and everything was good, so I disabled telnet. ssh was fine for a few tries, then life got very busy for a couple months. Now I've got a bit of free time again so I'm back to wanting to finish setting things up (add a git server to the DNS-323...) -- but can't seem to log into the machine. Presumably I've noted down an incorrect password (surprising, as I'm pretty anal), but I doubt the unit has corrupted its flash...

Anyway, short of it .. any easy way to impose a correction of password (or default it), or put a new /etc/passwd in (or whatever this is using for that), or would uninstall/reinstall funplkug or the firmware do this?

As long as I don't jeopardize the data, I'm cool; the admin interface works fine, too. So I can live without telnetd/sshd and all, I just really want to not have to

Thanks for any tips my friends!

Ah, I see a note I made couple months back -- tried to change password to some long pass (>8 chars), and then found a note saying it required pass to be <= 8 chars.. so apparently the set-password allowed long, but it only works wth short, so that buggered it up, possibly. (Assuming my note is correct.)

Perhaps this info helps?

Hey skeezix, sorry to hear about your trouble. Life sure does get busy sometimes!

Here would be my suggestion. Could you perhaps (1) rename the existing fun_plug and ffp folder to something like fun_plug_old and ffp_old; (2) recopy a fresh set of fonz's 0.5 so that telnet is enabled; and (3) then overwrite your old password? This is what I've done in the past when I was in trouble.

Once you've regained telnet access, if you need a reference on creating the new password (that is overwriting the old one) I like this in particular: how to change the ssh password

*g* We've a toddler around, so life has been busy the last 2 years, for sure Since I can't log in I can't inspect the mounts or the like (and I don't really know offhand what all funplug does, didn't look that close.)

I see a 'ffp' dir at the top level (in Volume_1 of course), and ffp.log and fun_plug -- I bet that last is a script, so I could figure out what the bootup process is *duh* Checking the ffp.log I see that it invokes the sh startup scripts in /ffp/start .. I bet a clever sed script in there could do what I need, or even a script to copy a plain /etc/passwd into place after backing up the old one, or something.

Anyway back to your idea ..

To 'remove' funpkug, can I really just rename /ffp to /ffp.bak or whatever and thats it?

I had thought funplug installation modified flash-ram or somesuch?

Or do you mean..

1) rename ffp to ffp.bak, fun_plug to fun_plug.bak (say)
2) Fine a new fonz package and unpack the ffp dir (I forget whats in his package offhand) and fun_plug script, without acually doing the whole installation process again?

A good tip my friend, thanks!

My best wishes to you and your family.

Someone more knowledeable will have to comment. But I dont think the fun_plug installation did anything *that* crazy.

Yes! That's exactly what I'm suggesting. Once you install the new fun_plug (current version is fonz's 0.5 which is found here: script and tar file) you simply (1) extract the tar file's contents to your root folder on Volume_1 to create a new 'ffp' folder; and (2) copy over the script file fun_plug (and rename it from fun_plug.sh if necessary). I couldn't believe it was that simple either—all thanks to Fonz. (3) Reboot your NAS and you'll regain telnet access.

Once you "revert" back to the basic installation of fun_plug, (4) follow the above instructions in the previous post to reset your password. This actually *will* be written to the memory so that your password is saved across reboots.

Lastly, (5) you should rename your more sophisticated ffp.bak and fun_plug.bak to the regular and you should be set with ssh access! Best of luck.

There's a simple way to reenable password-less telnet. See at the end of 'The root user' http://dns323.kood.org/howto:ffp#the_root_user

skeezix · 2009-06-24 16:54:01

fonz -- interesting; possibly bq041's replacement telnetd.sh might do it, or slipping in the usermod -p trick noted in the wiki there.

Seems I can't ftp into the NAS and modify those files, nor do it via SMB mount. (permissions -- the contents of that dir are locked by the NAS?)

Any other idea fonz?

Great advice fonz, many thanks!

As he noted, the fun_plug script will unjpack a fun_plug.tgz if it finds one, allowing you to overwrite the normally unwritable files or do other magic. The script referred to above just drops a new telnetd.sh startup script, whch sets up a non-password telnet daemon. *poof* Good to go.

Thaks!
