Yeah if you put the uid and gid options in your mount command, they should be mounted as the user you set. On a pi, this would be like,

code:

uid=pi,gid=pi

Full command would be something like:

code:

mount -t cifs -o username=pi,password=[pass],nofail,uid=pi,gid=pi //serverip/sharename /mnt/share

If you don't have a mini hdmi adapter and a usb otg adapter (with the correct dimensions! otherwise it's worthless) then you may want to consider picking them up.

The zero w doesn't use standard hdmi (the pi 4 uses hdmi micro, which is also incompatible), so you'd need it for display

The zero w also doesn't have standard usb ports, so you'll need the otg cable to plug a keyboard into it.

One nice thing about pi zero is that it takes very little power, so you can generally plug it into any usb slot and it works (the standard pi stuff tends to draw too much power). I'm working on some firmware that automatically plays movies when it's connected to a tv (since the tv can provide output via hdmi and power on the service port). Maybe you could use a bluetooth joypad and use it to play old console games?

# ? May 19, 2023 19:30

sb hermit: Dec 13, 2016

there are a lot of projects out there that convert a pi zero to a handheld gaming device but the additional hardware costs money

likely you could just get by with, as I mentioned, connecting it to a tv and then connecting a joypad via bluetooth

CIFS is not NFS

just want to repeat this

they are wildly different filesystems

it's dead simple to use and is a fine option if you have a secure network (i.e. you are't running it over the internet)

but it doesn't really do security. unless you use kerberos and a lot of other elbow grease and candle light, nfs doesn't even support encryption or logins. the most that pre nfs4 can do is only allow access to certain shares via the ip address of the client.

Anyways, since CIFS (aka SMB) works, just stick with that. It's what most small networks use without any issues.

What really made me want the beepberry is that they sourced blackberry keyboards for it. I never used one before, but I figure they've gotta be a better user experience than any other home made design. Also, as the pi0 improves over time, this should be a forward compatible drop in upgrade so it's a good candidate for a "forever" computer. I'm tired of throwing electronics away.

Thanks! NFS is different than CIFS. If you've used NFS with your other clients, then this would be a good start. But if you used CIFS or SMB, it may be worth using that instead. Just a heads up.

Anyways, we can keep using NFS for now. The security won't be great but it can be a start. First, you will want to go into the synology nfs settings and set squash to "no mapping". If it does what I think it does, then this will allow root to access your files. I pulled the UI information from here:

https://kb.synology.com/en-ph/DSM/help/DSM/AdminCenter/file_share_privilege_nfs?version=7

Next, you can try mounting again and see if things look a bit better:

code:

sudo mount -t nfs4 -o proto=tcp,port=2049,no_root_squash 192.168.1.247:/volume1/'Share Videos' /mnt/share

However, if this doesn't work, then please do the following:

code:

sudo mount -t nfs4 -o proto=tcp,port=2049,no_root_squash 192.168.1.247:/volume1 /mnt/share

sudo ls -lAd /mnt/share/'Shared Videos'

This will let us know who owns that directory and what its permissions are.

As you know, NFS doesn't use usernames and passwords (modern NFS uses kerberos for user authentication, security, and mapping which is a five thousand word post on its own) so buckle up for some more debugging.

yeah, disabling root squash on the server (which is the synology in this case) should really help things.

So just to be clear on my end, and I really ought to know this, SMB is the recommended �networked file drive� solution for Linux stuff correct? NFS is mainly for windows iirc, though it does SMB fine too.

E - googled and I have that backwards.

# ? May 22, 2023 02:01

sb hermit: Dec 13, 2016

it depends on what you're doing and what your resources are

if your systems and resources are already configured for nfs and you have the infrastructure for it, it's good, particularly for servers that talk to each other (like for storing databases, or whatnot)

if you have older unix systems, then it's still good

if you want to run virtual machines and store the disk images over NFS, it's a well supported use case

anytime you have unix systems talking to unix systems (or linux talking to linux), the test cases and scenarios will assume NFS

but it can be a big learning curve. NFSv4, in particular, has a lot of pitfalls and changes that NFSv3 and earlier did not.

On the other hand, SMB and CIFS are great if you have a lot of end user clients (desktops, tablets, laptops, etc) talking to a file server. Even modern Macintoshes will use CIFS for Time Machine (in the past, they supported AFP and AppleTalk only, which was mac specific). If you have a network with actual real users on desktops, you should use CIFS to have them talk to the file server. If you have servers talking to each other or to dedicated SANs, then the use case for NFS is bigger. It all depends on your requirements.

sb hermit posted:

Actually, CIFS is sort of the newer term, but it's also obsolete and SMB is the current term. CIFS was a rebranding of SMB 1.0 that Microsoft tried to standardize, but it wasn't meant to be and the later branding became SMB 2.0 and 3.0.

My own opinion is that you shouldn't try to mix Linux and SMB. My group administers close to 900 servers and the ones that operate as SMB clients are absolutely the most unreliable ones. If my coworker bangs his head against the wall long enough he can make them run decentish, then Microsoft releases some new security update and here we go again.

If I need Linux and SMB, I'd probably install Windows Server and turn it into Linux with WSL.

# ? May 22, 2023 03:19

Computer viking: May 30, 2011; Now with less breakage.

SMB on linux seems to work best with temporary userland mounts, and even then you run into annoying things like gvfs mounting to some horrible path with brackets and commas that confuses a lot of tools.

Disabling squash mapping should hopefully fix more access configuration issues.

If you still encounter issues, and "sudo chmod 755 /mnt/share" doesn't work, then please try this:

code:

sudo mount -t nfs4 -o proto=tcp,port=2049,no_root_squash 192.168.1.247:/volume1 /mnt/share

sudo ls -lAd /mnt/share/'Shared Videos'

sudo ls /mnt/share/'Shared Videos'

If this still doesn't work then we may have to try using a lower nfs version number or seeing if some synology web ui option was overlooked.

Looks like stock is still improving, like the raspberry pi man has been saying in interviews recently. I was sceptical initially as it was first mentioned at the start of the year, and nothing much seemed to change.
Zeros and 3As seem to be staying in stock ok, and even the 4s last more than a few hours now. CM4s and even the odd CM3s have appeared.
I got a zero to make a pseudo scsi thing for and old Akai sampler so that's cool. Use sd cards for 8 "hdd devices" rather than spend hundreds on one 30 year old 500mb hard drive. Good stuff.

Oh yeah, the raspberry guy has got the poshest English accent ever. Really hard to follow him, even as a brit who's heard plenty of posh English fuckers (usually barking orders and being entitled, though he seems to be a good egg)
