8: Device Ports
SecureLinx SLC User Guide
74
To connect to a device port to monitor and/or interact with it, or to establish an
outbound network connection:
connect direct <endpoint>
endpoint is one of:
deviceport <
Port #
or
Name
>
ssh
<
IP Address
> [port <TCP Port>][<SSH flags>]
where:
<SSH flags> is one or more of:
user <Login Name>
version <1|2>
command <Command to Execute>
tcp <IP Address> port <TCP Port>
telnet <IP Address> [port <TCP Port>]
udp <IP Address> port <UDP Port>
Notes:
To escape from the
connect direct
command when the endpoint of the
command is
deviceport
,
tcp
, or
udp
and return to the command line
interface, type the escape sequence assigned to the currently logged in user
(see
Setting up Local Users
on page 94 ). If the endpoint is
telnet
or
SSH
,
logging out returns the user to the command line prompt.
To escape from the
connect listen
command, press any key.
Setting up a user with an escape sequence is optional. For any NIS, LDAP,
RADIUS, Kerberos, or user, or any local user who does not have an
escape sequence defined, the default escape sequence is Esc+A.
Device Ports – Logging
The SLC products support port buffering of the data on the system's device ports as well
as notification of receiving data on a device port. Port logging is disabled by default. You
can enable more than one type of logging (local, NFS file, email/SNMP, or PC Card) at a
time. The buffer containing device port data is cleared when any type of logging is
enabled.
Local Logging
If local logging is enabled, each device port stores 256 Kbytes (approximately 400
screens) of I/O data in a true FIFO buffer. You may view this data (in ASCII format) at the
CLI with the
show locallog
command, through the CIFS share by viewing the text file
containing the contents of the FIFO buffer, or on the Device Ports – Logging web page.
The file containing the buffer is named <Device Port Number>_<Device Port Name>.log.
(For more information about the CIFS share, see
NFS and SMB/CIFS
on page 57.) You
clear the port buffer with the
set locallog clear
command.
Buffered data is normally stored in RAM and is lost in the event of a power failure if it is
not logged using an NFS mount solution. If the buffer data overflows the buffer capacity,
