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.
