Why is there a browser (text or otherwise) installed on the server?
This was an example. Servers do not have web browsers? Hah???? I do
occassionally use an x-session to fire up things on the server, as I do
have servlet programs that obey only localhost and write web content as
non root users, so having a web browser on the server does not hurt
really and I do know of many servers like that.
And the pam bit that logs keystrokes to auditd does log every keypress.
And it logs the program you were typing in.
https://bugzilla.redhat.com/show_bug.cgi?id=483086 is the functionality I'm describing.
Like I said - I only use it to log for root. People should not be considering actions done as root to be private
What I said refers to the whole picture. What you really want to do is
to correlate events that occur. Logging keystrokes gives you the
keyboard stream, but does not always help you to correlate what you type
and what happens at the OS layer. As for privacy, there are reasons that
I can tell you it's a bad idea to do it. For example, I have found that
my sysadmins type occasionally sensitive (as opposed to private) info,
such as rhn reg keys or ssh passwords. These do not really need to be
inside a text log file in plain text.

Auditing keystrokes will not always reveal the whole picture and is VERY
intrusive for people. How are you going to correlate (and prove) that when
you type something like http://www.abadsite.com , you are typing it on the
descriptor of the web browser and not a text word processor. Too much
noise for the data and too much invasion to privacy, never saw the point
really apart from folk that due keystroke based user authentication, which is
very error prone and it logs only some keystrokes to work, not everything.

I'm a fan of auditing root keystrokes and shipping them off the box - you
can see what happens if your server gets compromised or if you have a
disgruntled employee by setting up alerts on the log correlation box. Plus it
allows a historical view of an event that bash_history doesn't always -
especially if the admin doesn't use a shell that has a history. Auditing normal
users, however, typically isn't worth it.

It also strikes me as a) a great way to create an overwhelming amount
of data; b) useless - consider the user edits a script, suspends the
editing session, runs the script, forgrounds the editing session, and
undoes whatever code they put in. Oh, and c) over-the-top Big
Brother; I mean, there's oversight, and there's this: if there's this
mistrust of the employees, then perhaps management should either hire
trustworthy employees, or only allow trusted employees to work on the
systems.
mark, *not* a fan of the idea.

Hi Rob,
I'm logging command history of every user to remote syslog server.
It requires two steps on client side:
1) Add following function to /etc/profile:
function history_to_syslog
{
declare command
command=$(fc -ln -0)
logger -p local7.notice -t bash -i -- $USER : $command } trap
history_to_syslog DEBUG
2) Configure local syslog to resend logs to remote syslog
(/etc/syslog-
ng/syslog-ng.conf):
# Send local messages to central syslog server
filter f_filter7 { facility(local7); };
destination d_syslog_server { udp(xxx.xxx.xxx.xxx); }; log {
source(s_sys); filter(f_filter7); destination(d_syslog_server); };
Best regards,
Zbynek Vymazal

This should be an easy question.
I use Logwatch on all of my RHEL servers and would like for it to
also report on all commands that any user had typed when logged in
as well.
Something along the lines of UID: Command to give me an idea of who
was doing what at any given period of time.
I tried using snoopy but that gave me much more than I was looking
for.
I'm
now playing around with psacct and logger but was curious to know
what everyone else out there uses to monitor user activity besides
looking into everyone history file.
Thanks in advance!
~Rob
