|
|---|
| 2 | .SH NAME
|
|---|
| 3 | rhosts, hosts.equiv \- trusted remote users or hosts
|
|---|
| 4 | .SH SYNOPSIS
|
|---|
| 5 | .BI ~ user /.rhosts
|
|---|
| 6 | .br
|
|---|
| 7 | .B /etc/hosts.equiv
|
|---|
| 8 | .SH DESCRIPTION
|
|---|
| 9 | The per user
|
|---|
| 10 | .B .rhosts
|
|---|
| 11 | and the per system
|
|---|
| 12 | .B hosts.equiv
|
|---|
| 13 | files can be used to allow users to use
|
|---|
| 14 | .B rlogin
|
|---|
| 15 | or
|
|---|
| 16 | .B rsh
|
|---|
| 17 | without a password. The remote login services first check the system wide
|
|---|
| 18 | .B /etc/hosts.equiv
|
|---|
| 19 | file and then the
|
|---|
| 20 | .BI ~ user /.rhosts
|
|---|
| 21 | of the intended user. Both files contain lines of one of two forms:
|
|---|
| 22 | .PP
|
|---|
| 23 | .RS
|
|---|
| 24 | .I host
|
|---|
| 25 | .br
|
|---|
| 26 | .I host ruser
|
|---|
| 27 | .RE
|
|---|
| 28 | .PP
|
|---|
| 29 | The first form tells that any user from
|
|---|
| 30 | .I host
|
|---|
| 31 | is allowed to login to this system under the same name. The second form
|
|---|
| 32 | allows
|
|---|
| 33 | .I ruser
|
|---|
| 34 | from
|
|---|
| 35 | .I host
|
|---|
| 36 | to login.
|
|---|
| 37 | .PP
|
|---|
| 38 | Under MINIX 3
|
|---|
| 39 | .I host
|
|---|
| 40 | may be a pattern using
|
|---|
| 41 | .B "*"
|
|---|
| 42 | as a wildcard. One can use this, carefully one may hope, to allow an
|
|---|
| 43 | entire domain to log in.
|
|---|
| 44 | .I Host
|
|---|
| 45 | may also be an IP address, or a network specification in CIDR form, e.g.
|
|---|
| 46 | 172.16.102.64/27.
|
|---|
| 47 | .SH "SEE ALSO"
|
|---|
| 48 | .BR rlogin (1),
|
|---|
| 49 | .BR rsh (1).
|
|---|
| 50 | .SH NOTES
|
|---|
| 51 | MINIX 3 has no restrictions on becoming super-user remotely. Other systems
|
|---|
| 52 | usually require one to log in as a user and then use
|
|---|
| 53 | .BR su
|
|---|
| 54 | to become root.
|
|---|
| 55 | .PP
|
|---|
| 56 | You must use fully qualified hostnames, it is not possible to
|
|---|
| 57 | omit the domain part.
