Model For The Sol Proxy - Dell iDRAC6 User Manual

Model for the SOL Proxy

Telnet Client (port 623) ← → WAN connection ← → SOL Proxy ← → iDRAC6
server
When the SOL Proxy communicates with the Telnet client on a management
station, it uses the TCP/IP protocol. However, SOL proxy communicates with
the managed server's iDRAC6 over the RMCP/IPMI/SOL protocol, which is a
UDP-based protocol. Therefore if you communicate with your managed
system's iDRAC6 from SOL Proxy over a WAN connection, you may
experience network performance issues. The recommended usage model is to
have the SOL Proxy and iDRAC6 server on the same LAN. The management
station with the Telnet client can then connect to the SOL Proxy over a WAN
connection. In this usage model, SOL Proxy will function as desired.
Model for Redirecting SOL Over IPMItool
IPMItool ← → WAN connection ← → iDRAC6 server
The IPMI-based SOL utility, IPMItool, uses RMCP+ protocol delivered
using UDP datagrams to port 623. iDRAC6 requires this RMCP+ connection
to be encrypted. The encryption key (KG key) must contains characters of
zero or NULL that can be configured in iDRAC6 Web GUI or in iDRAC6
Configuration Utility. You can also wipe out the encryption key by pressing
the backspace key so that iDRAC6 will provide NULL characters as the
encryption key by default. The advantage of using RMCP+ is improved
authentication, data integrity checks, encryption, and the ability to carry
multiple types of payloads. See "Using SOL over IPMItool" or the IPMItool
website for more information:
http://ipmitool.sourceforge.net/manpage.html.
Disconnecting SOL session in iDRAC6 Command Line Console
Commands to disconnect a SOL session are utility oriented. You can exit the
utility only when a SOL session is fully terminated. To disconnect a SOL
session, terminate the SOL session from the iDRAC6 command line console.
When you are ready to quit SOL redirection, press <Enter>, <Esc>, and
then <t> (press the keys in sequence, one after the other). The SOL session
will close accordingly. The escape sequence is also printed on screen as soon as
a SOL session is connected. When the managed server is off, it takes a bit
longer to establish the SOL session.
