What does 'dhclient: suspect value in host_name option - discarded' mean?

Xavier2
Hi,

in the logs of my UTM 9.103 I see many errors(!) stating
'dhclient: suspect value in host_name option - discarded'

What's this or how can see what's really wrong or which host causes this?

    If your ISP is handing out a name with a blank character, that may be why. I thought that message was normally only displayed when dhclient read it's config file but it may also come up when dhclient receives it's lease information. There's not a lot of info from google on that error (just some stuff from Amazon AWS) so I had to dig into the source code of dhclient to make sense of it. [:)]

    Blank(whitespace) characters are not valid characters per the DNS naming specs so dhclient would throw an error. Your hostname is a valid DNS name though not resolvable anywhere except perhaps internally.

    I plugged the WAN Interface beyond another router instead of directly into the cable modem and the messages didn't show up.
    So my ISP's DHCP seems to be the one to blame.

    Thanks
    Xavier
