NAME
ugidd - uid/gid mapping daemons
SYNOPSIS
/usr/sbin/rpc.ugidd [ -P port ]
DESCRIPTION
ugidd starts a daemon that handles rpc requests to map uid/gids to
string names and vice versa. It is called by the nfsd(8) server when
the client and server do not share the same passwd file.
This version allows you to restrict access to the server through the
hosts_access(5) files when compiled with the -DHOSTS_ACCESS option.
Otherwise, ugidd could be used by anyone in the Internet to obtain a
list of all valid usernames on the client machine. For instance, to
restrict access to hosts on your class C IP network, you could add the
following lines to hosts.allow and hosts.deny:
# /etc/hosts.allow
rpc.ugidd: 192.168.1.
# /etc/hosts.deny
rpc.ugidd: ALL
OPTIONS
-P portnum or --port portnum
Makes ugidd listen on port portnum instead of some random port.
By default, ugidd will listen on some arbitrary port number
below 1024.
SEE ALSO
exports(5), inetd(8), hosts_access(5)
BUGS
The rpc program number is legal in that it lies in the 0x20000000 to
0x3fffffff ‘‘Defined by user’’ range, but is completely arbitrary.
