Description
Verify tcp_wrappers are not mandatory in the system
Setup
Make sure your favorite software that could be using tcp_wrappers is installed
rpm -q openssh-server openssh-clients
How to test
- Check if
tcp_wrappersis not installed:rpm -q tcp_wrappers - Check that
tcp_wrappers-develcan not be installed:dnf install tcp_wrappers-devel - Query repository for a list of packages, that still link against
tcp_wrappers:dnf repoquery --whatrequires 'libwrap.so.0()(64bit)'|grep x86_64
Expected Results
- Step #1 should return non-zero exit code and a message
package tcp_wrappers is not installed - Step #2 should fail --
No match for argument: tcp_wrappers-develor similar message - Step #3 should not return anything (assuming all the bugs mentioned in the Comment #10 of a bug #1495181 were fixed)
Optional
If you still see some of the packages directly depending on libwrap.so, first check unresolved dependent bugs before opening a new one. Also check the updates-testing repository.
