CHAPTER 5: SERIAL PORT, HOST DEVICE AND USER CONFIG
For Unauthenticated Telnet the default port address is IP Address:Port 6000 + serial port # (that is Port #s 6001 – 6048).
Enable or disable Web Terminal.
Enabling Web Terminal enables web browser access to the serial port via Manage > Devices > Serial using the Management Console’s
built in AJAX terminal.
Web Terminal connects as the currently authenticated Management Console user and does not re-authenticate. See Section 14.3 for
more details.
Enter an IP Alias (for the Network Interface, Management LAN or Out-of-Band/Failover).
A working IP Alias enables access to the serial port using a specific IP address, specified in CIDR format. Each serial port can be
assigned one or more IP aliases, configured on a per-network-interface basis.
A serial port can, for example, be made accessible at both 192.168.0.148 (as part of the internal network) and 10.10.10.148 (as part
of the Management LAN). It is also possible to make a serial port available on two IP addresses on the same network (for example,
192.168.0.148 and 192.168.0.248).
These IP addresses can only be used to access the specific serial port, accessible using the standard protocol TCP port numbers of
the console server services. For example, SSH on serial port 3 would be accessible on port 22 of a serial port IP alias (whereas on the
console server’s primary address, it is available on port 2003).
This feature can also be configured via the multiple port edit page. In this case, the IP addresses are applied sequentially, with the first
selected port getting the IP entered and subsequent ones getting incremented, with numbers being skipped for any unselected ports.
For example if ports 2, 3 and 5 are selected and the IP alias 10.0.0.1/24 is entered for the Network Interface, the following addresses
will be assigned:
Port 2: 10.0.0.1/24
Port 3: 10.0.0.2/24
Port 5: 10.0.0.4/24
Enable or disable Encrypt Traffic and enable or disable Authenticate. (These options should be either enabled or disabled as a pair.)
Enabling these two options turns on trivial encryption and authentication of RFC2217 serial communications using Portshare. For
strong encryption, use VPN.
Set an Accumulation Period.
Once a connection has been established for a particular serial port (such as a RFC2217 redirection or Telnet connection to a remote
computer) any incoming characters on that port are forwarded over the network on a character by character basis. The accumulation
period changes this by specifying a period of time that incoming characters will be collected before then being sent as a packet over
the network.
