‐T There are no user settings. is the domain name from which access is permitted.
Not that entering anything in this field will prevent all access unless the system has a valid DNS server
*FTP Site
This setting is used for updating earlier units. If this option is not present you have the later unit
with the 100 Base‐T Ethernet and Livewire capability. See Section 13 for how to upgrade the
Xstream. This is the site to which the Xstream will download new software from. If your firewall
allows FTP access, you can use the default which is ftp.telos‐systems.com . Or, you can enter
the IP address of a local FTP server.
This can be an IP address (see the rules above) or it can be an alphanumeric entry.
t
DEEP TECH NOTE!
When an alphanumeric entry is present, a domain name server (DNS) is queried for the IP
address of the computer using that domain. The reason we do so is that while the Zephyr.com
domain will remain constant, the IP address of our FTP server (ftp.zephyr.com) might very
well change periodically.
See below for a HOT TIP! on how to determine the current IP address of a given FTP server.
*FTP update
This setting is used for updating earlier units. If this option is not present, you have the later
unit with the 100 Base‐T Ethernet and Livewire capability. This option initiates the software
update process.
See Section 13 for additional information. You must enter an IP address and subnet mask (see
above). You will also need a gateway and DNS if you will be downloading software directly from
the Telos FTP site.
∗ Note: these options found only in older versions of the Zephyr Xstream.
