In the network configuration all parameters related to the network interfaces can be
changed. In the first section you can change the hostname and domain name. You can
also specify two nameservers and two SYSLOG servers. In the nameserver and
SYSLOG server fields you may enter an IPv4 or IPv6 address (the SYSLOG servers
can be specified as a hostname, too).
All information which is written to the LANTIME SYSLOG (/var/log/messages) can
be forwarded to one or two remote SYSLOG servers. The SYSLOG daemon of this
remote SYSLOG needs to be configured to allow remote systems to create entries. A
Linux SYSLOGD can be told to do so by using the command “syslogd –r” for
starting the daemon.
If you enter nothing in the SYSLOG server fields or specify 0.0.0.0 as the SYSLOG
server's addresses, the remote SYSLOG service is not started on your LANTIME.
Please be aware of the fact that all SYSLOG entries of the timeserver are stored in /
var/log/messages and will be deleted when you power off or reboot the timeserver. A
daily CRON job is checking for the size of the LANTIME SYSLOG and deletes them
automatically, if their size is exceeding a limit.
By specifying one or two remote SYSLOG servers, you can preserve the SYSLOG
information even when you have to reboot or switch off the LANTIME.
In the second section the possible network protocols and access methods can be
configured. You can enable/disable TELNET, FTP, SSH, HTTP, HTTPS, SNMP and
NETBIOS by checking/unchecking the appropriate check box. After you saved your
settings with the “Save” button, all of these subsystems are stopped and restarted (if
they are enabled).
The third section allows you to select the IP protocol 6. In this version the IPv4
protocol is mandatory and cannot be disabled, but a standalone IPv6 mode can be
reached by entering an IPv4 address “0.0.0.0” and disabling the DHCP client option
for every network interface of your LANTIME. By doing so, you ensure that the
timeserver cannot be reached with IPv4. Please note that TELNET, FTP and
