Hello

You're on kernel 5.18, so you have to use branch kernel_5.15 instead of master! Documentation is wrong at this point, sorry.

Best regards

Thanks a lot. Your work is very valuable.

[malec0101]

I can't use the module's functions. ncpmount, slist doesn't run. Does the module require additional software?

[EnzephaloN]

This is just the "filesystem-driver". The ncpfsutils are not included. Maybe you can find them on older linux distributions (for example maybe here: https://packages.altlinux.org/en/p8/srpms/ncpfs/rpms/ ). you need /usr/bin/ncplogin, /usr/bin/ncplogout, /usr/bin/ncpmap, /usr/bin/ncpmount and /usr/bin/ncpumount. Also you need a symlink /usr/sbin/mount.ncpfs -> /usr/bin/ncpmount .

[malec0101]

I assumed so. I am using Ubuntu 22.04. At the moment, I was unable to install older versions of the ncpfs package. At the installation stage, it shows an unpacking error. Installing from source code will crash. Apparently a deb package is needed that will suit my system. Thank you very much for your support and advice.

[EnzephaloN]

I think it's a bit too tricky to find a deb-package... Maybe this works: Grab http://ftp.altlinux.org/pub/distributions/ALTLinux/p8/branch/files/x86_64/RPMS/ncpfs-2.2.6-alt9.qa1.x86_64.rpm and unpack it. Inside in /usr/bin you will find the binaries I pointed above.
