UGIDD(8)UGIDD(8)NAME
ugidd - uid/gid mapping daemons
SYNOPSIS
/usr/sbin/rpc.ugidd
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 -DENABLE_HOSTS_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

The rpc program number is legal in that it lies in the 0x20000000 to
0x3fffffff ``Defined by user'' range, but is completely arbitrary.
