Brian,
Can you please clarify the statement you made below. I understood that
anything less than SSH v2.0 should not be used.
With the recent issues with ssh, it may be a sitting target.

re:
Cisco currently has no plans for v2.0 or later (it offers no advantage for
Telnet access)"

Subject: Re: Configuring PIX via TCP/IP Connection?


Harry,

Ahh, serial connectivity.  Do you have a 2509 or a 2511 access server with
an octopus cable?  You can Telnet to the access server and then gain
console access via serial cable to a locally attached device (PIX, router,
switch, etc...).

You have a number of options for configuring the PIX over the (TCP/IP)
network.  All assume that the PIX can be configured in advance.

As Jay pointed out you can configure Telnet to the PIX.  Permitting Telnet
access to the PIX is only allowed from the inside interface.  Any sessions
that attempt to initiate from the outside interface must be IPsec.  If they
are not IPsec, they are rejected (they can be configured but just don't
work, ugh).  You can define a range of addresses from the inside network
from which Telnet is allowed. That is configurable with a net mask so you
can narrow it to a range or an individual IP address.

You can configure the PIX to accept a Telnet session over the outside
(actually any) interface using IPsec.  You have a range of control over the
IP addresses that will be accepted from.  I'd suggest using a different
IPsec configuration for remote management as opposed to site to site
connectivity (pre-shared and DES is good).

You can configure SSH (Telnet) access to the PIX.  The PIX supports SSH
v1.5 implementations.  Cisco currently has no plans for v2.0 or later (it
offers no advantage for Telnet access).

PIX Device Manager (PDM) GUI uses SSL when connecting to the PIX.  PDM is a
v6.0 add-on (a separate file from the PIX OS).  You can use this from the
inside or the outside interface.  The IPsec session is still a requirement
for outside access.  I use PDM to manage a number of PIXen.  I created  a
web page on my management station that allows me to browse to any one of
the PIX.  Be careful though, I have found that some PCs cannot handle
running multiple SSL sessions well (more memory?).

In order to log Telnet management access to the PIX you'll probably want to
configure Syslog for either notifications (Syslog level 5) or informational
(Syslog level 6) or better.

In v5.3 you have Telnet, SSH and IPsec options.

In v6.0 (and later) the PIX OS implemented the "setup" feature.  If the PIX
starts and finds no configuration it will ask the console if the admin
wants to run through a setup dialogue.  The setup dialogue works in
conjunction with PDM, and sets the PIX up to allow PDM access from the
inside.

In v6.1 the PIX 501 does come with "plug and play" configuration.  That
pre-configures the PIX to expect a DHCP server on the outside interface
(PIX DHCP client) and act as a DHCP server to a pool of 256 inside IP
addresses.   You can order that same configuration on any new PIX but it is
standard on the 501.

Liberty for All,

Brian
