Nameservers
If DNS name servers are specified here, then these must be used to resolve symbolic host
names, i.e. at most of the points where an IP address is expected, a computer name can
also be used instead.
The name server setting is also sent to your DHCP client (TCU, PG) via the DHCP server of
the NCU, so that this can also work with symbolic names.
Value:
Default:
Timeservers
Here you can specify a list of NTP servers (Network Time Protocol) that can be used by the
NTPD on the NCU for time synchronization. The status of NTPD is output in the system
logfile /var/log/messages.
Value:
Default:

● Host name from the basesys.ini file, if set
● A name received from the DHCP server (if DHCP client mode and a name have been
● A default name ("NONAME_...")
Because the host name is also used as DNS name it must satisfy the corresponding
requirements of the RFC:
● ASCII letters (a-z, A-Z), numbers (0-9) and '-'
● max. 63 characters
