Chapter 15: Advanced Configuration
D. Set up the DHCP server
This is on Ubuntu with the isc-dhcp-server package installed. We assume you have already set this up server DHCP leases.
1. Add this entry to /etc/dhcp/dhcpd.conf
option space tripplite code width 1  length width 1;  
option tripplite.config-url code 1 = text;   
class “tripplite-demo-config” { 
   match if option vendor-class-identifier ~~ “^TrippLite/”; 
   vendor-option-space tripplite; 
   option tripplite.config-url “https://demo.example.com/opg/demo.o\
pg”;  
}
2. Restart the DHCP server with
 /etc/init.d/isc-dhcp-server restart
Appliances booting in configured mode will now be sent a config-url \
list from the server.
The config-url string is a space-separated list of URLs that will be tried in order. In secure mode, only the https URLs will 
be tried.  Demonstration
If you’ve followed all the instructions above, you should be able to \
demonstrate it by resetting a test unit.
If you have console access to the appliance, reset it in this way:
config -s config.console.debug=on -r console 
flatfsd -i
This will allow you to watch for error messages when backup-url runs.
E. Set up Wireshark for decrypting HTTPS connections
Wireshark can also be used to debug the situation. Since we have the server.key file, we can give that to Wireshark and 
inspect the packets, decrypted.
1. Start Wireshark
2. Go to Edit > Preferences
3. Scroll down to SSL
4. Click Edit... next to RSA keys list
5. Click New
6. Enter the IP address, port 443 protocol http and select the server.key file 
Close all those dialogs to get back to the main panel.

Chapter 16: Thin Client
The B092-016 has a selection of management clients (Firefox browser, SSH, Telnet, VNC viewer, ICA, RDP) embedded as well 
as the Tripp Lite PowerAlert software. With these, the B092-016 provides rackside control of computers, networki\
ng, telecom, 
power and other managed devices via serial, USB or IP over the LAN. 
This chapter provides instructions on configuring the thin clients and\
 using them locally and remotely. The thin clients can be 
controlled from the rack side using a direct monitor/keyboard/mouse conn\
ected to the B092-016 or remotely using a VNC 
connection from the remote user to the B092-016.
16.1 Local Client Service Connections
These client connections first need to be configured: 
• Select Connect: Add/Delete/Edit on the control panel
• Then select a Connect client (such as RDP) and click Add to configure the Host connection for that client service
• For each new Host you add, you will be asked to enter a L abel (enter a descriptive name) and a Hostname (enter the IP 
Address or DNS Name of the new network connected Host) and possibly a Username (enter the name you will use to 
log in to the Host)
• Once a Host has been added, you can select Edit and update the commands that will be executed in connecting the 
service to the existing Host

Chapter 16: Thin Client
• The sixteen serial ports are pre-configured by default in Console Serv\
er mode for the B096-016 / B096-032 / B096-048 
Console Server Management Switch or in UPS (PowerAlert) mode for the B092-016 Console Server with PowerAlert 
product. To change these settings, select Configure, which will load the local F\
irefox browser and run the Management 
Console. You can then reconfigure the serial ports as detailed in Chapter 4

16.1.4 Connect: SSH
SSH is typically used to log into a remote machine and execute commands.
• Select Connect: SSH on the control panel and click on the Host to be accessed
• An SSH connection window will be opened. Enter the SSH login password and you will be securely connected to the 
selected Host
The B092-016 SSH connection uses OpenSSH (http://www.openssh.com/) and the terminal connection is presented using rxvt 
(ou RXVT). You can find more details on configuration options in http://www.rxvt.org/manual.html

16.1.5 Connect: IPMI
The B092-016 control panel provides a number of IPMI tools for managing \
service processors or Baseboard Management 
Controllers (BMCs). These IPMI controls are built on the ipmitools program. Find more details on configuration options in http://
ipmitool.sourceforge.net/manpage.html
The ipmitool program provides a simple command-line interface to the BMC\
s and features the ability to read the sensor 
data repository (SDR),  display the contents of the System Event Log (\
SEL), read and set LAN configuration parameters, and 
perform remote chassis power control. The B092-016 Management Console al\
so has additional tools for controlling power 
units with IPMI interfaces (refer to Chapter 8). 
• Select Connect: IPMI on the control panel and select the Serial over L AN connection to be accessed
This will launch a Serial-Over-LAN session by running:
 # ipmitool -I lanplus -H hostname -U username -P password sol activate
The resulting serial character connection is presented in an rxvt (ouR XVT) window. Also the Serial-Over-LAN feature is only 
applicable to IPMI2.0 devices. 
• Select Logs: IPMI on the control panel and select the IPMI Event Log to be viewed
This will retrieve the selected IPMI event log by running:
 # ipmitool -I lanplus -H hostname -U username -P password sel info

16.1.6 Connect: Remote Desktop (RDP) 
• Select Connect: RDP on the control panel and click on the Windows computer to be accessed
• The rdesktop program in your B092-016 will be started, an RDP connection to the Remo\
te Desktop server in the selected 
computer will be opened, the rdesktop window will appear on your B092-016 screen and you will be prompted for\
 a 
password. (If the selected computer does not have RDP access enabled, t\
hen the rdesktop window will not appear.)
You can use Add/Delete/Edit to customize the rdesktop client (e.g. to in\
clude login username passwords). The command line 
protocol is: 
 rdesktop -u windows-user-id -p windows-password -g 1200x950 ms-windows-terminal-server-host-name
optionDescription
-aColor depth: 8, 16, 24

16.2 Advanced Control Panel  
16.2.1  System: Terminal 
Selecting System: Terminal on the control panel logs you in at the command line to the B092\
-016 Linux kernel. As detailed 
in Chapters 14 and 15, this enables you to configure and customize you\
r B092-016 using the config and portmanager 
commands or general Linux commands. 
16.2.2 System: Shutdown / Reboot
Clicking System: Shutdown on the control panel will shut down the B092-016 system. You will need to cycle the power to 
reactivate the B092-01. 
Similarly, by clicking System: Reboot, you will initiate a soft reset. With a soft reset, the B092-016 reboots with all settings 
such as the assigned network IP address, preserved. However a soft reset disconnects all Users and ends any SSH sessions 
that had been established. 
A soft reset will also occur when you switch OFF power from the B092-016, and \
then switch the power back ON. However, 
if you cycle the power while the unit is writing to flash, you could c\
orrupt or lose data, so the software Shutdown or Reboot 
from the control panel is the safer option.
16.2.3 System: Logout
Clicking System: Logout closes the local user log in session (and removes the control panel).\
 However, this does not logout 
remote users who may be logged into the B092-016 Console Server, or accessing attached devices using SSH tunneling.
16.2.4 Custom
The Custom button on the control panel enables you to customize your B09\
2-016 by adding buttons to the control panel that 
execute bash and other Linux commands you specify.
16.2.5 Status
These menu items give the user a snapshot of the serial port and IPMI de\
vice status.
16.2.6 Logs
These menu items give the user an audit log of B092-016 activity.
