Hello everyone , I want to implement a new firewall, detection system on my network composed of some 200 computers as follows: The fire wall would be a linux box with router, L7 iptable and also snort as IDPS system. These are my questions: 1. Is there any security consideration regarding putting all of these packages on the same server , that is to say that should I inevitably put IDPS and FW on two different linux boxes or they can all be put together on one linux box. 2. Is there any package that contains L7 iptables with snort or any other equally strong IDPS using GUI environment for manipulation and configurations? 3. Is there any other package at all that might have the same functionality; i.e., L7 filter and an IDPS with graphic user interface? Also I have a question on snort : Is it possible to have control on the size of uploaded files and not only tcp packets from my internal network to internet by L7 filter or Snort or any other software? If this can be done , then I will be able to prevent leakage of data from my internal network by malwares to malicious servers. Thanks

WALL(1) User Commands WALL(1)NAME
wall - write a message to all users
SYNOPSIS
wall [-n] [-t timeout] [-g group] [message | file]
DESCRIPTION
wall displays a message, or the contents of a file, or otherwise its standard input, on the terminals of all currently logged in users.
The command will wrap lines that are longer than 79 characters. Short lines are whitespace padded to have 79 characters. The command will
always put a carriage return and new line at the end of each line.
Only the superuser can write on the terminals of users who have chosen to deny messages or are using a program which automatically denies
messages.
Reading from a file is refused when the invoker is not superuser and the program is set-user-ID or set-group-ID.
OPTIONS -n, --nobanner
Suppress the banner.
-t, --timeout timeout
Abandon the write attempt to the terminals after timeout seconds. This timeout must be a positive integer. The default value is
300 seconds, which is a legacy from the time when people ran terminals over modem lines.
-g, --group group
Limit printing message to members of group defined as a group argument. The argument can be group name or GID.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
NOTES
Some sessions, such as wdm, that have in the beginning of utmp(5) ut_type data a ':' character will not get the message from wall. This is
done to avoid write errors.
SEE ALSO mesg(1), talk(1), write(1), shutdown(8)HISTORY
A wall command appeared in Version 7 AT&T UNIX.
AVAILABILITY
The wall command is part of the util-linux package and is available from Linux Kernel Archive <https://www.kernel.org/pub/linux/utils/util-
linux/>.
