NAME
ipmilan - IPMI LAN to System Interface Converter
SYNOPSIS
ipmilan [-c configfile] [-i ipmidevice] [-d] [-n]
DESCRIPTION
The ipmilan daemon allows an IPMI system interface using the OpenIPMI
device driver to be accessed using the IPMI 1.5 LAN protocol.
ipmilan supports the full authentication capabilities of the IPMI LAN
protocol.
ipmilan supports multiple IP addresses for fault-tolerance. Note that
messages coming in on an address are always sent back out on the same
address they came in.
OPTIONS
-c config-file
Set the configuration file to one other than the default of
/etc/ipmi_lan.conf
-n Stops the daemon from forking and detaching from the
controlling terminal. This is useful for running from init.
-d Turns on debugging to standard output. You generally have to
use -n with this.
CONFIGURATION
Configuration is accomplished through the file /etc/ipmi_lan.conf. A
file with another name or path may be specified using the -c option.
The following fields are used in many commands:
boolean May be "true", "false", "on" or "off".
priv An IPMI privilege level. This may be "callback", "user",
"operator", or "admin".
auth An IPMI authorization type. This may be "none" for no
authentication, "straight" for straight, in-the-clear password
authentication, "md2" for use MD2 message digest authentication, or
"md5" for using MD5 message digest authentication.
addr IP-address [UDP-port]
IP-address specifies the IP address to use for an IP port. Up to
4 addresses may be specified. If no address is specified, it
defaults to one port at 0.0.0.0 (for every address on the
machine) at port 623.
UDP-port specifies an optional port to listen on. It defaults to
623 (the standard port).
PEF_alerting boolean
Turn PEF alerting on or off (not currently supported).
per_msg_auth boolean
Turn per-message authentication on or off.
priv_limit priv
The maximum privilege allowed on this interface.
allowed_auths_callback [auth [auth [...]]]
auth specifies allowed authorization levels for the callback
privilege level. Only the levels specified on this line are
allowed for the authorization level. If this line is not
present, callback authorization cannot be used.
allowed_auths_user [auth [auth [...]]]
auth specifies allowed authorization levels for the user
privilege level. Only the levels specified on this line are
allowed for the authorization level. If this line is not
present, user authorization cannot be used.
allowed_auths_operator [auth [auth [...]]]
auth specifies allowed authorization levels for the operator
privilege level. Only the levels specified on this line are
allowed for the authorization level. If this line is not
present, operator authorization cannot be used.
allowed_auths_admin [auth [auth [...]]]
auth specifies allowed authorization levels for the admin
privilege level. Only the levels specified on this line are
allowed for the authorization level. If this line is not
present, user authorization cannot be used.
user usernum enabled username password max-priv max-session [auth [auth
[...]]]
usernum specifies the user number for the user. Note that user
number 0 is invalid, and user number 1 is the special
"anonymous" user, whose username is ignored. This value may be
up to 63, the maximum possible IPMI user. If you want anonymous
access, you must have a user number 1.
enabled is a boolean that specified whether the user is enabled
or not.
username specifies the name of the user, specified as a name.
password specifies the password of the user, specified as a
name.
max-priv specifies the maximum privilege level allowed for the
user.
max.sessions specifies the maximum number of session the user
may open.
auth specifies the allowed authorization types for the user.
Only the specified ones are allowed, so if none are specified,
the user will be disabled.
guid name
Allows the 16-byte GUID for the IPMI LAN connection to be
specified. If this is not specified, then the GUID command is
not supported.
Blank lines and lines starting with ‘#’ are ignored.
SECURITY
ipmilan implements normal IPMI security. The default is no access for
anyone, so the default is pretty safe, but be careful what you add,
because this is access to control your box. straight and none
authorizations are not recommended, you should probably stick with md2
or md5.
SIGNALS
SIGHUP
ipmilan should handle SIGHUP and reread it’s configuration files.
However, it doesn’t right now. It might in the future, for now
you will have to kill it and restart it. Clients should handle
reconnecting in this case. If they don’t, they are broken.
ERROR OUTPUT
At startup, all error output goes to stderr. After that, all error
output goes to syslog.
FILES
/etc/ipmi_lan.conf
SEE ALSO
ipmi_ui(1)
KNOWN PROBLEMS
Currently, ipmilan does not implement writing the config file. IPMI
commands to change configuration options are accepted, but the
permanent writing of the changes does not currently work.
