I'm using sed for Windows at a WinNT command prompt. Wrapping the expressions with single quotes doesn't work. I have to use double quotes. Is this the norm for the Windows implementation? (2 Replies)

itsme
$ ssh xxx.xxxx.xxx.xxx 'ITSME=itsyou; echo $ITSME'

The command simply puts how many jobs each user is... (2 Replies)

PADS(8) System Manager's Manual PADS(8)NAME
pads - Passive Asset Detection System
SYNOPSIS
pads <DhUvV> <-c file > <-d file > <-g group > <-i interface > <-n network(s) > <-p file > <-r file > <-u file > <-w file > <expression>
DESCRIPTION
PADS is a libpcap based detection engine used to passively detect network assets. It is designed to complement IDS technology by providing
context to IDS alerts.
Goals:
- Passive: Records and identifies traffic seen on a network without
actively "scanning" a system. There will never be a packet sent from
the pads application.
- Portable: Has the ability to be placed easily on a remote system.
Does not require additional external libraries other than those
associated with libpcap.
- Lightweight: Logging is sent to a simple CSV file. There is no need
for a database or other data repository installed on the local
machine. All correlation is done outside of the pads program.
OPTIONS -h Display help / usage information.
-D Run PADS in the background (daemon mode).
-d file
Dump banner data into a libpcap formatted file. This feature will dump the matched packet or the first 4 packets of an unmatched
connection into a specified file. This can be used to further identify a service and also aid with signature development.
Please keep in mind that this feature must be compiled into the application in order to use it. This can be done by adding
'--enable-banner-grab' to the 'configure' step.
-g group
This switch allows you to specify a group that PADS will drop to after the libpcap interface has been initialized.
-h Display help
-i interface
Specify an interface to be used.
-n network list
Specify a set of networks to be monitored. Only assets that exist within these networks will be recorded. The networks should be
specified in the following format: 10.10.10.0/24,192.168.0.0/16 .
-p pid file
This switch allows you to specify a PID file to be used in conjunction with daemon (-D) mode.
-r file
Read packets from a libpcap formatted file.
-u user
This switch allows you to specify a user that PADS will drop to after the libpcap interface has been initialized.
-w file
Dump data into a file other than assets.csv.
expression
selects which packets will be processed. Please see tcpdump(1) for details on the libpcap primitives.
