system.rootdaemonrc, .rootdaemonrc - access control directives for ROOT daemons

ROOTDAEMORC, $HOME/.rootdaemonrc
/etc/root/system.rootdaemonrc, $ROOTSYS/etc/system.rootdaemonrc

This manual page documents the format of directives specifying access control directives for ROOT daemons. These directives are read from a text file whose full path is taken from the environment variable ROOTDAEMONRC. If such a variable in undefined, the daemon looks for a file named .rootdaemonrc in the $HOME directory of the user starting the daemon; if this file does not exists either, the file system.rootdaemonrc, located under /etc/root or $ROOTSYS/etc, is used. If none of these file exists (or is readable), the daemon makes use of a default built-in directive derived from the configuration options of the installation.

lines starting with '#' are comment lines.
hosts can specified either with their name (e.g. pcepsft43), their FQDN (e.g. or their IP address (e.g.
directives applying to all host can be specified either by 'default' or '*'
the '*' character can be used in any field of the name to indicate a set of machines or domains, e.g. pcepsft* applies to all 'pcepsft' machines in the domain ''. (to indicate all 'lxplus' machines you should use 'lxplus*' because internally the generic lxplus machine has a real name of the form; you can also use 'lxplus' if you don't care about domain name checking).
a whole domain can be indicated by its name, e.g. '', '' or '.ch'
truncated IP address can also be used to indicate a set of machines; they are interpreted as the very first or very last part of the address; for example, to select, any of these is valid: '137.138.99', '137.138', '137`, '99.73'; or with wild cards: '137.13*' or '*.99.73`; however, '138.99' is invalid because ambiguous.
the information following the name or IP address indicates, in order of preference, the short names or the internal codes of authentication methods accepted for requests coming from the specified host(s); the ones implemented so far are:

Method nickname code

UsrPwd usrpwd 0

Methods not specified explicitly are not accepted.

Lines ending with '´ are followed by additional information for the host on the next line; the name of the host should not be repeated.

Valid examples:

All requests are denied unless specified by dedicated directives.
Authentication mechanisms allowed by default are 'usrpwd' (code 0)
137.138. 0
Authentication mechanisms allowed from host in the domain 137.138. ( are 'usrpwd' (code 0)
Requests from the lxplus cluster from users 'qwerty' and 'uytre' can authenticate using 'usrpwd'.
Requests from the pcep* nodes can authenticate using 'usrpwd' when accessing the 'rootd' daemon ; user 'qwerty' cannot use 'usrpwd'.
