I installed twonky but no longer need the telnet service started by fun plug... how can i stop telnet and only keep twonky going????

bq041 · 2008-05-31 00:37:27

telnet in and:

Code:

/ # chmod 644 /ffp/start/telnetd.sh

Then reboot.

jrusso · 2008-05-31 00:42:31

i entered that line of code

no confirmation message came up just another / #

does this mean it worked.... i rebooted can i check to see if it's shut off... and if i need to re-activate how do i do that????

KyleK · 2008-05-31 00:46:01

No confirmation means it worked. Next time you reboot Telnet will not be started.
Reactivation is quite difficult though (it's possible either via a special php page if you have lighttpd installed, or you need to put the fun_plug.tgz back on the device)

Why do you want to disable telnet anyway? If its for security reasons, I suggest enabling ssh instead (needs a bit of setup) and then disabling telnet.

bq041 · 2008-05-31 00:48:51

You can reactivate it really easy via ftp. chmod is a command that ftp can send.

From command line ftp:

Code:

quote chmod 755 /ffp/start/telnetd.sh

assuming that the ftp root is set to Volume_1.

well it was for security reasons, but i already turned it off... i only really cared about twonky working for streaming to my xbox... don't know much about the possibilities of telnet or ssh, is there any real reason i would need telnet if my main use for the nas is streaming and storing media???

jrusso · 2008-05-31 00:51:16

i use flash fxp to ftp to the nas how do i send the chmod code and what is the actual code???

bq041 · 2008-05-31 00:54:32

I don't use flash fxp, so I do not know. What OS are you using. Most come with a command line ftp that is easy for this.

jrusso · 2008-05-31 00:56:19

windows xp.... do i just use the ftp command in run...

bq041 · 2008-05-31 01:06:02

No. At run type cmd and hit enter. This will open a command shell for XP. At the command prompt do the following:
type: ftp <ip-address-of-DNS> -- Do not include the <>
enter a valid login name
enter a valid password
type: ls and hit enter -- This will list the contents. You should see the ffp directory if this user's root directory is Volume_1.
type: quote chmod 755 /ffp/start/telnetd.sh
type: quit
type: exit

Just make sure you set up a user on the ftp to have a root of Volume_1 first.

jrusso · 2008-05-31 01:15:50

everything works up to chmod request says "could not change perms on ffp/start/telnetd.sh operation not permitted" my user has read write permission to volume 1 so i don't know why i'm getting that???

bq041 · 2008-05-31 01:40:33

Sorry about that. From your first post, I didn't know you were going to turn it back on, so I left out a step. No problem, though. Here is what you need to do. Drop the attached file on your Volume_1 and reboot. This is a special fun_plug.tgz that will put in only the telnet. Let me know what happens. Once this is done, telnet in and do this before disabling telnet

Code:

 chown <valid-user-name> /ffp/start/telnetd.sh

Then you can chmod it off and will be able to turn it back on via ftp.

will this affect or conflict with the fun plug i already installed... or will it just add a line to the already existing fun plug file to re open telnet... in my mind i see the new tgz file unpacking upon reboot and messing with the existing ffp directory... but i'm probably wrong... just to be sure i just drop the attatched file into volume_1 reboot and everything will still be the same only telnet will be re-activated??? i don't want to have to reinstall twonky or anything...

bq041 · 2008-05-31 07:52:58

Not exactly. Inside this .tgz file is 1 file, telnetd.sh. When fun_plug sees the .tgz file, it will overwrite the telnet script with an active one. It does nothing more.

jrusso · 2008-08-13 23:03:41

This did not work.... when i go to putty click telnet put my dns ip address and try and open a telnet connection a blank dos prompt looking window opens followed by the usual windows error sound and instantly closes...

jrusso · 2008-08-13 23:21:07

I was able to get the message for closing.... when i try to connect it says "connection closed by remote host" then "Network Error: connection refused" ...

Please check the ffp.log file. Post the lines at the end of the file, starting from '* Running /ffp/etc/rc ...'.

jrusso · 2008-08-14 00:19:50

sorry my find tool in notepad gave me the first running and no others so i posted from there.... i see now you only need the end...

Try the attached fun_plug.tgz. bq041 made a small mistake. fun_plug.tgz must not contain the full path /mnt/HD_a2/..., but only subdirectories of /ffp. Also it should be packed with a sufficiently old version of tar (e.g. tar-1.13) for compatibility with the firmware tar.

Code:

$ tar tzvf fun_plug.tgz 
drwxr-xr-x root/root         0 2008-08-13 22:27 start/
-rwxr-xr-x root/root       169 2008-04-19 14:26 start/telnetd.sh

Sorry, please try again. I've replaced the attached tarball above with a new version.

jrusso · 2008-08-14 00:46:28

Worked like a charm thanks a lot... is it a big security risk to leave telnet enabled... or is it not such a big deal??? also one other question i just ordered the new model of popcorn hour and was wondering if you knew whether it will simply pick up the dns 323 shared folders over the network or are there steps to be taken??? thanks again for your help
