.SH DESCRIPTION
|
|
These programs support remote access across the Internet. All expect the
|
|
network connection to be standard input, output, and error. They are normally
|
|
started from scripts in
|
|
.B /rc/bin/service
|
|
(see
|
|
.IR listen (8)).
|
|
.PP
|
|
.I Telnetd
|
|
allows login from a remote client.
|
|
There are three types of login:
|
|
.TF anonymo
|
|
.TP
|
|
.I normal
|
|
Normal users log in by encrypting and returning a
|
|
challenge printed by
|
|
.IR telnetd .
|
|
The user can use either the
|
|
.IR netkey
|
|
program
|
|
(see
|
|
.IR passwd (1))
|
|
or a SecureNet handheld authenticator to encrypt the challenge.
|
|
.B /lib/namespace
|
|
defines the namespace.
|
|
.TP
|
|
.I noworld
|
|
Users in group
|
|
.B noworld
|
|
in
|
|
.BR /adm/users
|
|
authenticate with a password in the clear.
|
|
.B /lib/namespace.noworld
|
|
defines the namespace.
|
|
.TP
|
|
.I anonymous
|
|
User
|
|
.B none
|
|
requires no authentication.
|
|
.B /lib/namespace
|
|
defines the namespace.

.PP
|
|
.I Rexexec
|
|
executes a command locally for a remote client. It uses the
|
|
standard Plan 9 authentication (see
|
|
.IR authsrv (6)).
|
|
.PP
|
|
.I Ftpd
|
|
runs the Internet file transfer protocol. It supports both
|
|
implicit and explicit ftps. Users may transfer
|
|
files in either direction between the local and
|
|
remote machines.
|
|
There are two types of login:
|
|
.TF anonymous
|
|
.TP
|
|
.I normal
|
|
Normal users authenticate with their username and password when using tls.
|
|
.BI /usr/ username /lib/namespace.ftp
|
|
or, if that file does not exist,
|
|
.B /lib/namespace
|
|
defines the namespace.
|
|
.TP
|
|
.I anonymous
|
|
Users
|
|
.B anonymous
|
|
and
|
|
.B none
|
|
require no authentication.
|
|
The argument to the
|
|
.B \-n
|
|
option (default
|
|
.IR /lib/namespace.ftp )
|
|
defines the namespace.

Anonymous users may not store files.

|
|
.I Socksd
|
|
is a SOCKS4 and SOCKS5
|
|
proxy server allowing non-Plan 9 machines to access the
|
|
outside network.
|
|
The net to use for outgoing calls can be specified
|
|
with the
|
|
.B -o
|
|
.I outside
|
|
and the internal network is specified with
|
|
.B -x
|
|
.I inside
|
|
(for UDP relay).
|
|
If not specified,
|
|
.I inside
|
|
and
|
|
.I outside
|
|
will default to
|
|
.BR /net .
|
|
.PP
|
|
.I Hproxy
|
|
is a simple HTTP proxy server.
