NAME

       rootd - The ROOT file server daemon

SYNOPSIS

       rootd [options]

DESCRIPTION

       This manual page documents briefly the rootd program.

       rootd is a ROOT remote file server daemon.

       This small server is started either by inetd(8) (or xinetd(8)) when a client requests a connection to a  rootd server or by hand (i.e. from
       the command line). The  rootd server works with the ROOT TNetFile, TFTP and TNetSystem classes. It allows access to remote directories  and
       ROOT files in either read or write mode from any ROOT interactive session. By default rootd listens on port 1094, assigned to it by IANA.

STARTING VIA (X)INETD
       To run rootd via inetd(8) or xinetd(8) the port 1094 must be assigned to rootd in /etc/services; the following line should be added, if not
       present:

              rootd     1094/tcp

       If the system uses inetd, add the following line to /etc/inetd.conf:

              rootd stream tcp nowait root <bindir>/rootd rootd -i

       where <bindir> is the directory you have installed rootd in.

       The inetd(8) daemon must re-read its configuration file to become aware of the new service. This can be done either by killing and restart-
       ing it manually

              kill -HUP <pid inetd>

       or, if SYSV init(8) scripts are used, by restarting it, e.g.

              /etc/init.d/inetd restart

       If the system uses xinetd(8) instead, a file named 'rootd' should be created under /etc/xinetd.d with content:

              # default: off
              # description: The rootd daemon
              #
              service rootd
              {
                   disable         = no
                   flags           = REUSE
                   socket_type     = stream
                   wait            = no
                   user            = root
                   server          = <bindir>/rootd
                   server_args     = -i
              }

       where, again, <bindir> is the directory you have installed rootd in.

       The xinetd(8) daemon must be restarted:

              /sbin/service xinetd restart

       If  you installed ROOT using some pre-compiled package (for example a Redhat Linux or a Debian GNU/Linux package), this may already be done
       for you.

       The above configuration examples start the daemon with superuser privileges. Please refer to the inetd(8) or  xinetd(8)  documentation  for
       ways of limiting the privileges.

STARTING BY HAND

       You can also start rootd by hand running directly under your private account (no root system privileges needed). For example to start rootd
       listening on port 5151 just type:

              rootd -p 5151

       Notice: no & is needed rootd will go in background by itself.

ANONYMOUS LOGINS

       rootd can also be configured for anonymous usage (like anonymous ftp). To setup rootd to accept anonymous logins do  the  following  (while
       being logged in as root):

       1      Add the following line to /etc/passwd:

                 rootd:*:71:72:Anonymous rootd:/var/spool/rootd:/bin/false

              where you may modify the uid, gid (71, 72) and the home directory to suite your system.

       2      Add the following line to /etc/group:

                 rootd:*:72:rootd

              where the gid must match the gid in /etc/passwd

       3
               Create the directories:

                 /var/spool/rootd
                 mkdir /var/spool/rootd/tmp
                 chmod 777 /var/spool/rootd/tmp

              Where /var/spool/rootd must match the rootd home directory as specified in the rootd /etc/passwd entry.

       4      To make writable directories for anonymous do, for example:

                 mkdir /var/spool/rootd/pub
                 chown rootd:rootd /var/spool/rootd/pub

              That's all.

       If  you installed ROOT using some pre-compiled package (for example a Redhat Linux or a Debian GNU/Linux package), this may already be done
       for you.

       Several remarks:

       *      You can login to an anonymous server either with the names anonymous or rootd.

       *      The passwd should be of type user@host.domain Only the @ is enforced for the time being.

       *      In anonymous mode the top of the file tree is set to the rootd home directory, therefore only files below the home directory can  be
              accessed.

       *      Anonymous mode only works when the server is started via inetd(8) or xinetd(8).

ABOUT PASSWORD AUTHENTICATION

       In  system using shadow passwords, full access to the password field of the user information structure requires special privileges; this is
       typically granted if rootd is started by inetd(8) or xinetd(8), as the in above examples. If the daemon is started  in  unprivileged  mode,
       either  from  a  regular  account  or  by  (x)inetd  with  reduced privileges, password-based authentication require users to create a file
       $HOME/.rootdpass containing an encrypted password (using crypt(3)). The system tests the existence of this file before checking the  system
       password files. An encrypted password can be created in the following way:

              perl -e '$pw = crypt("<secretpasswd>","salt"); print "$pw0'

       storing the output string in $HOME/.rootdpass .

       If  the  $HOME/.rootdpass  does not exists and the system password file cannot be accessed, rootd attempts to run the authentication via an
       sshd(8) daemon.

OPTIONS

       -b <tcpwindowsize>
              specifies the tcp window size in bytes (e.g.  see  http://www.psc.edu/networking/perf_tune.html).  Default  is  65535.  Only  change
              default for pipes with a high bandwidth*delay product.

       -d <level>
              level of debug info written to syslogd 0 = no debug (default), 1 = minimum, 2 = medium, 3 = maximum.

       -D <rootdaemonrc>
              read  access  rules  from file <rootdaemonrc>. By default <root_etc_dir>/system.rootdaemonrc is used for access rules; for privately
              started daemons $HOME/.rootdaemonrc (if present) is read first.

       -f     run in the foreground (output on the window); useful for debugging purposes.

       -i     indicates that rootd was started by inetd(8) or xinetd(8).

       -noauth
              do not require client authentication

       -p <port#>[-<port2#>]
              specifies the port number to listen on. Use port-port2 to find the first available port in the indicated range. Use  0-N  for  range
              relative to default service port.

       -r     files can only be opened in read-only mode

       -s <sshd_port#>
              specifies the port number for the sshd daemon used for authentication (default is 22).

       -T <tmpdir>
              specifies the directory path to be used to place temporary files; default is /usr/tmp. Useful when running with limited privileges.

       -w     do  not check /etc/hosts.equiv, $HOME/.rhosts for password-based authentication; by default these files are checked first by calling
              ruserok(...); if this option is specified a password is always required.
