Hi,

I am trying to dry-run the dhclient program to request a lease from the
server for debugging purposes. At the same time, I am already holding a
lease on the same interface, which is why I don't want to release the
existing lease, as I have no decent access to the remote machine.
According to the man page, I should be able to run dhclient with "-n" to
do just that, but:

# dhclient -d -v -n -w wlp59s0

No interfaces command -n and  requested interface wlp59s0
Usage: dhclient [-4|-6] [-SNTPRI1dvrxi] [-nw] [-p <port>] [-D LL|LLT]
                [--dad-wait-time <seconds>] [--prefix-len-hint <length>]
                [--decline-wait-time <seconds>]
                [--address-prefix-len <length>]
                [-s server-addr] [-cf config-file]
                [-df duid-file] [-lf lease-file]
                [-pf pid-file] [--no-pid] [-e VAR=val]
                [-sf script-file] [interface]*
       dhclient {--version|--help|-h}

If you think you have received this message due to a bug rather
than a configuration issue please read the section on submitting
bugs on either our web page at www.isc.org or in the README file
before submitting a bug.  These pages explain the proper
process and the information we find helpful for debugging.

I originally stumbled over this bug on a different Linux distro, but
have no good way to report a problem there atm. But that way I am very
confident that this is an upstream problem.



Kind regards,
Toni
