Fedora 30 – authentication failed

[rengland]

Downloaded and installed  NoMachine v 6.6.8_5_x86_64 and installed on Fedora 30

I have it running successfully on Fedora 29 but when I attempt to start the server on Fedora 30 I get the message

“Authentication failed, please try again”

The same thing occurs when I attempt to enable changes for the server settings.

Repeating the attempt makes no difference. During the installation a message about the inability to find libcrypt.so.1 appeared.When I run

$ ldd nxserver.bin

I see the following (I don’t know if this is pertinent):

libnxh.so => not found
libnxhs.so => not found
libnxhc.so => not found
libcrypt.so.1 => not found

I find nothing in /usr/NX/var/log that shows failures occurring but I may not be looking in the correct place.

Has any one else successfully installed and run NoMachine on this very recent release.

SOLVED:

The upgrade from Fedora 29 to 30 requires that the package libxcrypt-compat be installed for NoMachine v6.6.8_5_x86_64 to function properly . The following is taken from the library description.

Perhaps this is something for the NoMachine developers to investigate for future releases.

This package contains the library providing the compatibility API
for applications that are linked against glibc's libxcrypt, or that
are still using the unsafe and deprecated, encrypt, encrypt_r,
setkey, setkey_r, and fcrypt functions, which are still required by
recent versions of POSIX, the Single UNIX Specification, and various
other standards.

All existing binary executables linked against glibc's libcrypt should
work unmodified with the library supplied by this package.

Thank you.

NoMachine does not use any of those “unsafe and deprecated” functions, by the way Fedora changed the suffix of libcrypt.so from 1 to 2. That is, Fedora now provides libcrypt.so.2 but NoMachine depends on libcrypt.so.1.

So that’s why, at the moment, you need libxcrypt-compat package to restore the required dependency from libcrypt.so.1.
