Description:

When wifi if off, the hostid command can give correct values. But when wifi is enabled, hostid gives 00000000. This starts to happen after recent system upgrades. I tried to downgrade the coreutils package but it didn't fix the problem. I suppose some other packages are responsible for the problem.

Additional info:

* coreutils 8.26-1

Steps to reproduce:

1. upgrade all packages to the newest version.

2. connect to wifi

3. enter 'hostid' in command line, the output is "00000000"
This task depends upon

This program doesn't do much useful, what are you trying to use if for here?

Anyway, this is likely because you don't have an entry in /etc/hosts for the hostname you're on.

The license manager from a commercial software uses it for verification. Thank you for your help, adding hostname to /etc/hosts fixes the problem. I think this bug report may be closed.

LOL, using hostid for licensing is a really horrible idea, it's not even close to unique and can change easily. Not your issue, though.
