The original rootd server can be obtained from:
but, for it to work correctly with CFITSIO one has to use a modified
version which supports a command to return the length of the file.
This modified version is available in rootd subdirectory
in the CFITSIO ftp area at
This small server is started either by inetd 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 class. It allows remote access to ROOT database files in either read or write mode. By default TNetFile assumes port 432 (which requires rootd to be started as root). To run rootd via inetd add the following line to /etc/services:
rootd 432/tcpand to /etc/inetd.conf, add the following line:
rootd stream tcp nowait root /user/rdm/root/bin/rootd rootd -iForce inetd to reread its conf file with
kill -HUP <pid inetd>. 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 5151Notice that no & is needed. Rootd will go into background by itself.
Rootd arguments: -i says we were started by inetd -p port# specifies a different port to listen on -d level level of debug info written to syslog 0 = no debug (default) 1 = minimum 2 = medium 3 = maximumRootd 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):
- 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. - Add the following line to /etc/group: rootd:*:72:rootd where the gid must match the gid in /etc/passwd. - Create the directories: mkdir /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. - To make writeable directories for anonymous do, for example: mkdir /var/spool/rootd/pub chown rootd:rootd /var/spool/rootd/pubThat's all. Several additional remarks: you can login to an anonymous server either with the names "anonymous" or "rootd". The password should be of type email@example.com. 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.
