[split] Is it ok to leave PCH on 24/7?
Hi guys,
is there a way to prevent internal HD to spin-up when unauthenticated ftp/smb request comes from network in standby mode?

Split as the question was not really on topic and it deserves a thread of its own.
Perhaps you should change the thread title as well.

I meant - threre's no issue with leaving it on "forever", but spinning up a harddisk at 2am is really annoying. And it pnly because somebody connects from the internet to port 21 and gets username/password prompt. Even if he doesn't pass, system reads something from disk.

Could this be treated as a bug to be fixed in future releases?

I don't see how you can treat that as a bug. How is any device to know if the connection on the other end is authentic or not until the username/password challenge is met?

If you must have port 21 redirected to the NMT from the internet then consider using the router to only allow access during certain hours.

Or IP filtering, allowing only the IP address you know you'll connect from.

Well.. bug is not exact word...
I meant something like cache user database file in RAM (that contains only one username anyway). When authentication is not successful, then ftp server doesn't need to access harddrive.

Well, there is only a finite amount of ram in the unit and to cache the authentication for all the protocols could be a problem. I don't know of any device that does this.

I seriously doubt, they would action anything like this. If it really bothers you, I would suggest finding another means to achieve your end result. Also consider, what are the number of NMTs out there compared the the ones co-located in sleeping areas? Might make for a good poll?

Well, one thing is is is annoying during night. The second thing is, it keeps harddrive spinning almost continuously 24/7 - and this is my main concern - couldn't it harm an HD?
Limiting access based on IP or time is not an option for me, I have mates all arround the world.
Userdatabase on NMT contains 1 (one) pair of username-password (hardcoded limit). I'm wondering there's no space in RAM for that.

Actually, a drive spinning 7/24 is not a big issue. Many OS drives spin/run 7/24. The bigger problem seems to be parking/unparking all the time.

I did suggest limiting access times via the router but if you have friends all around the world then they would need 7/24 access because of the different time zones.

Place your request here: http://www.networkedmediatank.com/forumd...php?fid=41 and see how far it goes. If others want the same thing, then it might get noticed by Syabas.

A little offtopic: a HDD is best left running always. Most wear and tear is caused by startup/shutdown, due to mechanical wear and temperature changes.

You could use a different port like 1021 and forward that to port 21 of your PCH through your router

I think, you might be correct. My personal results seem to suggest this but has there been any real testing in this area? Got a URL?

Maybe i don't really get what you are talking about when you say "somebody connects from the internet to port 21 and gets username/password prompt" and if this case happens often or not but what i can tell is that when i shape my yamj, which is stored on the internal pch hdd, from a home networked pc, it indeed makes the pch hdd to spin up but when i stop to access to the pch the hdd spins down itself moments later, as it does when i access to a webservice for example.
By the way i had to disable the torrent and the ng clients to sort this out.

I had a similar problem but solved it by not using the built-in ftp server on the NMT.

What I did was install Cerberus FTP Server (free for home use) on a windows-based computer in my office, set up individual accounts for each of my friends with their own usernames and passwords. Then directed their "root" drive to be z:\ drive (the NMT).

The only things I have to watch for are:
1. ensure the drive is properly shared and accessible from the windows box;
2. the ports on the router are configured to allow the ftp connection through;
3. they all only have upload and download permission (not delete, make dir, edit, or otherwise change anything); and
4. makes sure both the nmt and the windows boxes are powered up and Cerberus is running before I go to bed at night.

I also automated the last using a little proggy that runs in the background of Windows, Z-Cron (also free for home use) and is far better than Windows' built-in scheduler.

This way I allow a select few to access the files on the NMT during my own "downtime" and the internal HDD only spins up when properly authorised peeps access the server.

Cerberus FTP Server: http://www.cerberusftp.com/

Z-Cron for Windows: http://www.z-cron.com/

HTH HAND Smile

[Edit] Actually, I have to clarify that a bit. I've just discovered that the ftp server is not directing through to the Popcorn, but is instead going to a directory on my HDD that I use to pass AV files through to the Popcorn.
