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?

    That error message indicates that the UTM's dhclient doesn't like the host name it's being told to send to the dhcp server. As that name has to be in proper DNS form, the client is discarding it. For most ISP's that use DHCP to assign IP's to their client it doesn't really matter as the ISP discards what you suggest and uses their own.

    What did you set your UTM's fqdn to when you initially setup the unit?

    This message is the only one begging with 'dhcpclient' in the logs.

    The UTM's hostname since first installation is 'astaro.foobar.local'

    But thanks to your answers I noticed that my ISP sends a hostname 
    with a blank.
    It this the reason?
