I am right there with you Chumbo, Putty wont let me it. I disabled the admin account months ago because of the hacking and my new admin account which is not named admin will not accept my password. just chasing my tail here.
For Putty to connect you need to have SSH enabled on your NAS and be using the proper port number.
For QNAP it’s under Control Panel > Network & File Services > Telnet / SSH
There’s a checkbox to allow SSH and and entry for what port to use (I believe it defaults to 22)
It’s recommended for Security reasons to disable SSH unless you need it. So be sure to disable it when you’re done.
Ok, another minor advance and some tips to other newbies like me…you can’t use the usual Ctrl+V for pasting as in Windows. Copy the password as usual but to paste it into Putty, you need to use the Shift+Insert key, let go of those keys and then press the Enter key. (this is the kind of things I thought warrant a step-by-step tutorial because I can’t believe EVERY Plex user knows this!?)
So I finally logged in the NAS using Putty and I’m greeted with…
Could not chdir to home directory /share/homes/MyUserName: No such file or directory
So what next? I’m guessing something involving sudo…but I still have no idea what that is??
What a PIA this whole process is. I wish we could get a bit more hands-on help for all this. Why do I need to figure out every step for myself??
I just want to watch movies, not learn to be an engineer!
I recommend you read my later post, it might help 
EUREKA!!! It finally worked!! 
I had to spend an annoying amount of time looking at Linux tutorials to learn to navigate the commands and find my way but it’s finally done. Pheeew!
Awesome this tool was quickly developed to solve this problem but I feel a step-by-step tutorial for newbies for whom words like: Putty, SSH, sudo, etc… mean absolutely nothing, would have been in order.
I think a 3-5 min video tutorial would have done the job and saved me (and probably many others) hours of trying to figure what this gibberish means.

Dane22, I am very frustrated at this point. Can you give me instructions as to completely wiping Plex off my QNAP Nas TS-673 so I can re-install it . I am not a programmer and I am stuck trying to use putty which will not connect with my server even after going thru the steps to enable it. Or give me some detailed instructions as to how to fix it. You would think a script and an update could be written to fix this problem.
lazy-e, I’m like you, a total novice in all this Putty stuff but since I succeeded in finally resolving this whole mess, let me see if I can offer a little help.
So I’m not going to tell you how to remove Plex but how I got the whole thing to work.
I’m going to assume you are as ignorant as I was.
Putty…I’ve found it to be very erratic. Sometimes it would work, other times not and yet I seemed to be doing the exact same thing. So there already, my advice is try the same thing many times with minor variations like restarting Putty or the Plex server (I even restarted the NAS!).
The pasting of the password in Putty is done by Shift+Insert key. Important…you will not see the password! It appears as if you had done nothing but it’s there, just press Enter after that.
This is the part that was most erratic for me and caused me to restart Putty many times because it often resulted in an error and refusing me access
Then - I don’t know if you fell victim to Deadbolt? - I realized I had changed the default port for SSH on the NAS which was normally Port 22 as is default in Putty. So matching the two ports finally got me in the NAS through Putty (had changed it because the Deabolt attack).
For now, I won’t go any further as getting this far is a prerequisite for any problems that might come after. But rest assured, after that it gets easier as is just a matter of getting familiar with a few Linux commands which I will gladly help you with if necessary.
PS I also had forgotten to stop Plex as given in these instructions. In fact, you are better off looking for help on that thread which is more specifically geared towards the tool as it applies to Linux-based NAS like the QNAP.
I hope some of this will help…hang in there!
Man, what a mess =). I spent hours troubleshooting on my own and found this thread luckily. Will try reclaiming, is that right? Could we update the top post so folks don’t need to scroll through the entire thread?
Edit/update: Also, watch out for it forcing HTTP-only and not accepting HTTPS connections. I thought I had other qnap issues but it was that, then reclaimed, now successful.
So I am still stuck with putty not letting me log in. I have the repair file in place, extracted it. and have yet to get putty to let me in.
I finally got putty to log into my server. I had to:
disabble my VPN
turn off my firewall
reinstate my old admin file
Now that I have it I need help as to where to go next:
I have tried the CD command (show directory ?) and get no such file or directory
Heres what I have:
My data is in datavol1
the file name is home where I inserted the file and opened it. (I need to know if its the latest version)
Can you type out for me the commands I need to get this done?
Everything should hopefully be outlined in this post
Ok, I have used DOS but Linux looks different. First, I dont know what the root is or it is not showing. I have tried to see files but I cannot figure out where the file Is looking at the Putty. I have figured out how to change files and directories, look to see whats in the directories but nothing looks like it does in the interface. What is the path to the information I need. I placed the file in a directory named home on my qnap in root I guess. I figure there is a path to the QNAP system to this file that I need to get started.
Please share a screen capture
Sorry, I need a screen capture of the procedure where you upload the file, since clearly you can’t find it
As an alternative, in the console type:
cd /
find -name UserCredentialReset.sh
Note above might take some time, since it’ll search your entire QNAP for the file
You can get to the correct directory by in a terminal to type
cd /share/home
Ok, So in screen shot ssh 2, I try your command and it says permission denied.
In screen shot ssh 3, I try to go to the directory and it dosent exhist. I then try to see the contents and I get a default index, then I look to see the hidden contents and it is also not there.
I then play with the sudo comand (I have no idea hoe to work that) thinking maybe I dont have the privileges I need even in my admin account?
