Dial-back
The SLC advanced console manager waits for a peer to call the SLC unit, establishes a text
(command line) or PPP connection, authenticates the user, and if the SLC 8000 advanced console
manager is able to determine a dial-back number to use, hangs up and calls the dial-back number
to establish either a text or PPP connection.
For text connections, the user will be prompted for a login and password, and will be
authenticated via the currently enabled authentication methods (Local Users, NIS, LDAP, etc).
The site list will be searched for a site that (a) the
Login/CHAP Host
matches the name that
was authenticated, (b)
Authentication
is set to PAP, and (c) the
Port
is set to
None
or
matches the port the modem is on.
If a matching site is found, its
Timeout Logins
,
Dial-back Number
,
Allow Dial-back
, and
Dial-back Delay
parameters will be used for the rest of the dial-back connection instead of the
parameters configured for the modem. Once the remote server is authenticated, if
Allow Dial-
back
is enabled for the site and a
Dial-back Number
is defined, the SLC unit will hang up and
wait
Dial-back Delay
seconds before initiating the dial-back. The SLC 8000 advanced
console manager will dial, prompt the user again for a login and password, and a CLI session
will be initiated. The user will remain connected to the SLC unit until they either logout of the
CLI session, or (if
Timeout Logins
is enabled) the CLI session is terminated if it has been
idle.
For PPP connections, the user will be authenticated via PAP or CHAP (determined by the
Authentication
setting for the modem). For PAP, the Local/Remote User list will be used to
authenticate the login and password sent by the PPP peer, and the site list will be searched for
a site that (a) the
Login/CHAP Host
matches the name that was authenticated, (b)
Authentication
is set to PAP, and (c) the
Port
is set to
None
or matches the port the modem
is on. For CHAP, the site list will be searched for a site that (a) the
Login/CHAP Host
and
CHAP Secret
match the name and secret sent in the CHAP Challenge response by the PPP
peer, (b)
Authentication
is set to CHAP, and (c) the
Port
is set to
None
or matches the port
the modem is on. If the remote peer requests PAP or CHAP authentication from the SLC 8000
advanced console manager, the
Remote/Dial-out Login
and
Remote/Dial-out Password
configured for the modem (not the site) will be provided as authentication tokens.
If a matching site is found, its
Dial-back Number
,
Allow Dial-back
,
Dial-back Delay
,
Dial-
out Login
,
Dial-out Password
,
Negotiate IP Address
,
NAT
, and
Modem Timeout
parameters will be used for the rest of the dial-back connection instead of the parameters
configured for the modem. Once the remote server is authenticated, if
Allow Dial-back
is
enabled for the site and a
Dial-back Number
is defined, the SLC unit will will hang up and wait
Dial-back Delay
seconds before initiating the dial-back. The SLC 8000 advanced console
manager will dial, and if the remote peer requests PAP or CHAP authentication, provide the
Dial-out Login
and
Dial-out Password
as authentication tokens. Once authenticated, a PPP
session will be established using either negotiated IP addresses or specific IP addresses
(determined by the
Negotiate IP Address
setting).
Dial-on-demand
The SLC unit automatically dial outs and establishes a PPP connection when IP traffic destined for
a remote network needs to be sent. It will remain connected until no data packets have been sent
to the peer for a specified amount of time.
When this modem state is initiated, the SLC 8000 advanced console manager searches the site
list for all sites that (a) have a
Dial-out Number
defined, (b) have a
Static Route IP Address
,
Static Route Subnet Mask
and
Static Route Gateway
defined, and (c) the
Port
matches the port
the modem is on. A dial-on-demand connection will be started for each, waiting for IP traffic
destined for a remote network.
When IP traffic needs to be sent, the SLC unit dials the appropriate
Dial-out Number
for the site,
