This whole area is system admin is a pain in the butt. Perderabo is right about training, unless you have people who consdier logging in to be a chore, i.e., lazy.
Using TMOUT works (as Google said), so do the idle daemons. But then you get complaints because you set the time out values too large or too small, too hot, too cold...
Some of our programmers have written little ditties to keep their processes on just about forever -- like this user:
Get people to use the unix lock utility. And if they have a PC used as a terminal then set up mandatory screensavers with passwords. Longterm, you'll be in better shape than trying to kill idle processes. IMO.
Hello,
I administer a NetBSD (1.6.2) server that receives remote logins over telnet with users running Csh. I wish to be able to occasionally bring up exactly what these users are doing. Echoing their consoles to mine would be ideal, but I cannot find any information on how this would be... (1 Reply)
Hi,
I have been asked if it is possible to track the last time a specific user logged in to the sysetm.
checked my documentation but can't see it there - google is not being very helpful either.
I wonder if someone here can help - it will be much appreciated.
Thanks

Hello,
Does any one knows any tools or method to monitor users all activities on Solaris 8, including command and its result. Similar to 'script' ???
Thanks

Hello,
First post so bear with me....i've done lost of searches on this and did not find a definitive answer.
I need to be able to capture in log every single keystroke a user performs, I am aware that the script command can be used to do this, however, here is my dilemma/problem.

Hi there,
I'm looking for some help to get a little script done that shows me (or counts) only the added lines from an SVN repository of one specific user. Anybody has an idea?

What commands would you recommend in order to monitor things like when a user logs on to a server, assuming you know that user's name on the server? (2 Replies)
Write a tool that will be displayed in real time, what user connects or disconnects from a system that uses this tool :))
Maybe anyone can help me? (2 Replies)
Need some help in coming up to log all the activity that is used with our common "unix account".
Ideally I am looking for to log the activity in a "separate" file for each session or login until the user logout, I would like to capture the date/time and terminal login and record all the ... (3 Replies)
Hi All
Please can you help me with the following issue:

runqueue
RUNQUEUE(9) BSD Kernel Developer's Manual RUNQUEUE(9)NAME
choosethread, procrunnable, remrunqueue, setrunqueue -- manage the queue of runnable processes
SYNOPSIS
#include <sys/param.h>
#include <sys/proc.h>
extern struct rq itqueues[];
extern struct rq rtqueues[];
extern struct rq queues[];
extern struct rq idqueues[];
struct thread *
choosethread(void);
int
procrunnable(void);
void
remrunqueue(struct thread *td);
void
setrunqueue(struct thread *td);
DESCRIPTION
The run queue consists of four priority queues: itqueues for interrupt threads, rtqueues for realtime priority processes, queues for time
sharing processes, and idqueues for idle priority processes. Each priority queue consists of an array of NQS queue header structures. Each
queue header identifies a list of runnable processes of equal priority. Each queue also has a single word that contains a bit mask identify-
ing non-empty queues to assist in selecting a process quickly. These are named itqueuebits, rtqueuebits, queuebits, and idqueuebits. The
run queues are protected by the sched_lock mutex.
procrunnable() returns zero if there are no runnable processes other than the idle process. If there is at least one runnable process other
than the idle process, it will return a non-zero value. Note that the sched_lock mutex does not need to be held when this function is
called. There is a small race window where one CPU may place a process on the run queue when there are currently no other runnable processes
while another CPU is calling this function. In that case the second CPU will simply travel through the idle loop one additional time before
noticing that there is a runnable process. This works because idle CPUs are not halted in SMP systems. If idle CPUs are halted in SMP sys-
tems, then this race condition might have more serious repercussions in the losing case, and procrunnable() may have to require that the
sched_lock mutex be acquired.
choosethread() returns the highest priority runnable thread. If there are no runnable threads, then the idle thread is returned. This func-
tion is called by cpu_switch() and cpu_throw() to determine which thread to switch to. choosethread() must be called with the sched_lock
mutex held.
setrunqueue() adds the thread td to the tail of the appropriate queue in the proper priority queue. The thread must be runnable, i.e. p_stat
must be set to SRUN. This function must be called with the sched_lock mutex held.
remrunqueue() removes thread td from its run queue. If td is not on a run queue, then the kernel will panic(9). This function must be
called with the sched_lock mutex held.
