In this video we're going to be hooking a 30 year old machine to a modern Asustor NAS and look at the configuration and security challenges involved with that.
We'll be exploring several aspects of the SMB protocol, including different dialects / versions / protocol negotiation, user authentication and guest access.
Many thanks to Asustor (www.asustor.com/) for providing me with the unit. I'm sure we'll be able to create lots more retro content with it.
Enjoy

Awesome video! My knowledge of SMB just quadrupled because of this video. Keep up the great works and yet again it's great to have you back in the retro community.

@ricardoberlimfonseca2182 5 месяцев назад

thanks for the SMB setup. I have to put and old microscope at work on a share, and it runs DOS 5.0 (I guess). Now it will have access to the net share! :)

@stuartcastle2814 6 месяцев назад

As a tech support person, with some fairly detailed knowledge of security, I can say that the best advice for securing most devices is do a combination of things. 1) Only enable what you need. Don't enable things like web servers unless you are planning to use them. Disable/uninstall them when finished. 2) Use a strong password. Preferably randomly generated, and use a password manager to remember it, if feasible> 3) Don't expose any device to the Internet unless you need to. Use a firewall (even if it's just one built into your router). It may be nice for you to have access to your NAS from outside your network, but how much could you lose if someone else got access? 4) Do not use an account with Admin rights unless you have to. 5) Make the the software and firmware on any devices you use is up to date.. This includes any networking hardware, such as routers, modems and switches.

@RetroSpector78 6 месяцев назад

Excellent points. I hoped I touched all of these points in the video as well. Majority of security related issues with these NAS devices are people that for convenience start opening up all kinds of ports on their router / firewall, opening a whole range of attack vectors to these devices. There have definitely been issues with third party apps on these devices, but I do believe that locking everything down on your route / firewall level is a first good line of defense. I would be pretty difficult to perform any SMB related attacks if no access from the outside is allowed.

Thank you for running through this! I completely forgot about adding "lanman auth" to my smb config years ago when I built my NAS for my retro computers and instead added a FTP server that lists the NAS' contents for my Win3.11 system. I made that 1 line change to my smb config file and now I can enjoy mapped drives on my win3.11 PC :) So much better. THANK YOU. Gotta love the forgotten networking knowledge of yesteryear

@RetroTechChris 6 месяцев назад

Fantastic! I love the level of detail, this video will be an evergreen video for explaining all of the SMB concepts and a great resource! One "fun" note, Samba 4.15.13 was the last version before SMB1 began to be deprecated. I host my SMB1 server on a Raspberry Pi, and as of Bookworm, the "shipped" Samba version is 4.17.x. As such, I've started to build Samba from source! I have a procedure for it if helpful.

If you love retro, how about you update the firmware to allow the config to be updated for retro from the web UI, by allowing the older protocols and password formats without dropping into SSH? You could obviously hide them by default under an "Advanced" config with appropriate warnings as to the security implications.

@@LBXComputers I think Asustor has already incorporate changes to facilitate retro usage. I've relayed my findings to them but ultimately it is up to them to decide what they do with it.

@@LBXComputers We absolutely have. We have maintained support for lower versions of SMB. We added many similar workarounds to our FTP implementation at the advice of Phil's Computer Lab. I am one person and not a software developer so it absolutely is me performing the advocacy as well as guiding our software team to implement them and also add it to their busy schedules. I can't promise overnight service as I only received the findings from Retrospector78 and need time to parse the info, digest it, and spit it back out in a way that is palatable to management and how to implement it in a way that helps assuage any concerns management might have. But, we do actually have FTP working in MS DOS right now. I fought hard for that.

I built myself a dedicated retro lan, and my central datastore is an old iomega ix2-200 cloud edition. Of course the files are backed up again on a truenas, but it works like a charm. My NAS can speak SMB1, but I usually only use FTP, because this is supported by a much wider range of computers (of that time).

@icepee9252 5 месяцев назад

Systemd allows for a file system change monitoring. You could set up a script that triggers whenever smb.conf is changed to add your amendments. You might also be able to hook into the web update scripting. However, while cleaner, may be more involved.

@colinstu 6 месяцев назад

Neat to show how to do the native file sharing with old sw + new nas. So many just enable FTP on their NAS and use that instead to transfer files with old PCs ... easier sure but not nearly as "fun"

@JimLeonard 5 месяцев назад

Heads up: SAMBA has already stated that all support for SMB1 will be dropped in the next version, so alternate methods will be needed in the future. (Likely a docker container running older versions of SAMBA.)

@thetaleteller4692 6 месяцев назад

Missed your videos, I like the calm way you explain things. Did you finally managed a way to get smb.conf settings persistent? like with a startup script updating the file and restarting the service. Another approach might be a docker container with a custom samba server on a different IP.

@ASUSTOR_YT 6 месяцев назад

I can promise one thing, that I will ask for this to be implemented so that it is persistent. I might need time though to convince them.

@alanharkleroad4376 5 месяцев назад

Very interesting video. I have already seen enough to know you can network with DOS and call BS on Vo-Tech teacher for saying you couldn't.

@UpLateGeek 6 месяцев назад

You could make this a lot more secure by running a separate instance of smbd with SMBv1 and lanman enabled from inside a docker container, then restricting access to this only from specific IP addresses, and making sure you configure a static IP address on those machines or reserve them on your router's DHCP server or whatever. I don't know about this NAS specifically, but most I've seen either have docker built-in or allow you to install it.

@giornikitop5373 6 месяцев назад

true, but you will have to use different ports for the smb services and all, so they won't conflict. not sure if smb port definitions can be changed in old dos/win31 or they are hardcoded.

@UpLateGeek 6 месяцев назад

@@giornikitop5373 I believe you can use the ipvlan driver to assign a separate IP address to the container, otherwise I think it's also possible to bind docker to a different interface/sub-interface on the host with a different IP address.

@sjogosPT 5 месяцев назад

In a home network is too overkill. I have a VM runing that mounts a network share and re-share as a smbv1 with no password and full write permissions inside my home lan. No problems here, its my lan.

@GigAHerZ64 6 месяцев назад

It is so much better to not mess around with your NAS, but instead to create a simple and small Debian Netinstall VM and configure it to consume your NAS shares over SMB3 and then *re-share* them over SMB1. You have your standard linux and you don't have to keep that VM running all the time, as it is unsecure to use anything under SMB3.

@nickwallette6201 6 месяцев назад

I considered doing something like this, but ultimately, if you have a closed network where only trusted clients have access; you have good security hygiene; and you actually keep separate, offline backups (or you only store data you can afford to lose), then... meh.

Why not use NFS, or even FTP, if security is a concern? The performance would be better too. Nothing about SMB on Windows 3.11 or MS-DOS 6.22 is secure, as SMBv1 was deprecated like 10 years ago. It’s off by default now everywhere, and shouldn’t be enabled on the NAS. There’s no real reason to enable TCP in DOS mode, it uses far too much memory and has minimal software support. Stick to using IPX for DOS if you want networking there, it’s lightweight and everything supports it. Keep TCP in the windows layer, it’s easier to manage files from File Manager anyway.
