Re: [bug-inetutils] inetd patch: server args passed incorrectly

Not quite so. The last part of each inetd.conf entry takes the form

    server program arguments

where `server' is the full pathname to the program to be executed,
`program' is the value for argv[0] (sic!), `arguments' are any arguments
the program might need (see man inetd for more derails).

Use the following line:

rlogin  stream  tcp  nowait  root  /usr/sbin/rlogin rlogin -o

If you wish to protect it by tcpd:

rlogin  stream  tcp  nowait  root  /usr/sbin/tcpd /usr/sbin/rlogin -o
