RISC OS 5.30, LanMan98, Windows 11 shares

Hello all,
Is it actually possible to make this work? i.e. mount a Windows share from Windows 11, on to RISC OS 5.30?

I have installed LanMan98, and if I click the “Net” icon, I can see my PC there, but regardless of settings, I cannot get a share to mount.

On Windows I have enabled SMB1, and I’ve turned on all printer/file sharing, along with 40 or 56 bit encryption.

The shares will mount on my other Windows computer no problem.

On RISC OS, the furthest I get is an error of “Session refused (NetBIOS name not present)”.

Before I spend too much time on this, has anybody got this to work?

All the best

First you need to enable SMBv1 in the Windows settings – as you did.

Furthermore usually with some of the security features enabled or even due to use HyperV is enabled on Windows 11 and thus your Windows 11 system has more than one IP address. Calling “ipconfig” on command line will show that listing one or more vEthernet adapters.

LanManFS will probably not work since it still does a NETBIOS lookup, gets all IP addresses of your Windows 11 host and picks the first one and thus in my case always a HyperV one which fails; it does neither try the better one (same subnet as RISC OS) or try both. So LanManFS is out of the gameplay for me.

LanMan98 does the same lookup but as work-around allows you to specify the IP address in the host name as “host” with “host” being the host name and “x.×.×.x” the IP address to use. With this the connection works.

Downside with LanMan98 is that since a while it will show remote files with German umlauts in the directory listing but can’t access them (LanManFS can access them BTW).

What will not work is to use just an IP address – so you want to use the host notation in LanMan98 – and if you’re from UK you probably are not impacted by file names with special characters :-)

Hope this helps…

Windows networking seems to behave differently for no obvious reason. I have a Win11 laptop, and I have just connected both LanManFS v2.70 and LanMan98 v2.08 to a shared disc on the laptop, using just the server name (not an IP address). I can open the Filer on it and read and save files from both mounts.

I only remember enabling SMB1 and setting the shares up on Windows when I got it earlier this year. Previously I had Win10pro, and had used LanManFS and LanMan98 with that for years without problems.

Sorry – not a lot of help, but it is possible!

Thanks both for the replies, I’ve tried getting my PC to have only one IP address, and now I’m connected directly to it via Ethernet, still no joy. I was previously using the new wifi support in RISC OS 5.30, but it’s proving a little flaky for me, so went back to wired Ethernet.

I’ve tried NFS too, but OmniClient is saying it’s not a supported protocol. I’m happy to run an NFS server on my PC if that might be easier?

I found my previous sligthly more detailed post on this topic: https://www.riscosopen.org/forum/forums/4/topics/19056.

With LanMan98 you can have more than one IP on Windows 11 by using host notation – and you might want to enable the “application guard” which implies your Windows 11 PC to have an additional IP address.

I had exactly the same issue some time ago. Someone then advised me to create a second user on the Windows 11 side and call that user name in the LanMan98 mount. That solved the problem.

Sounds like the sort of problem I have trying to persuade 2 Windows machines to share with each other.

I seem to recall disable simple sharing and ensuring there was either a matching user/password or guest access.

I just tried it making a brand new empty share, and a new user, and it worked! I have a mounted share!

Thanks to everybody who helped out.

Cheers!

Is the reverse actually possible? I mean, is it possible to access a RISC OS disk from Windows?

There is a very flaky Samba server implementation for RISC OS. It’s 32 bit but probably not ARMv7 or later.
