[Shivkumar]

Hi,

In the below output of who command, pts/1 and pts/2 indicates what type of terminals ? I mean users has logged in by which method to the box ?

user1 pts/1 Jun 12 08:53
user2 pts/2 Jun 19 10:15

Thanks,
shiv

So many parameters for who.

Try

who -T

and man who.

Shalom Shiv,

pts/1 do designate psuedo terminals.

As the term implies its a really a terminal tarcking connection.

There is no relation to the termain type at all.

pts/1 can be vt100, vt220, hp TERM type, anything your system is set up to perform.

The ttyp devices are different and indicate a login via probably a mux or other serial device sharing scheme.

HI SHiv,
hope u find out pts from SEP's reply.
and little more:
who -R --->u can find out the ip address of the users.
simple command to give lot of info is the single letter "w".

Your listing above shows two very different methods of connecting to your computer. The ttyp# names are for serial ports, perhaps a modem or direct-connect terminal. The pts names refer to LAN or network connections. If you want to know the type of terminal (Wyse, VT100, Hyperterminal, HP terminal, etc), there is no way to determine this without asking each user to tell you what $TERM reports in their session.

If you must determine the terminal type automatically for each user, edit the file /etc/profile and add something like this:

MYTERM=$(ttytype -s)
echo "$LOGNAME $(date) $(tty) $MYTERM" >> /tmp/logins.history

This will tell you what each user has as a terminal.

Actually, this is cleaner:

echo "$LOGNAME $(date) $(tty) $(ttytype)" >> /tmp/logins.history

Bill, in my 11i system,
# ttytype -s
TERM='vt100'; export TERM;
LINES=24; export LINES;
COLUMNS=80; export COLUMNS;
ERASE='^?'; export ERASE;
root@hpspool1 [ / ] #

# tty
/dev/pts/ta

but

#set
TERM=xterm
TMOUT=0
TZ=IST-5:30

what is wrong?

Sekar,

You wrote:

This indicates that you are running a dumb terminal emulator.

> #set
> TERM=xterm
> TMOUT=0
> TZ=IST-5:30

This indicates that you did not login using telnet since there is virtually no environment. Your TERM variable is set to xterm which means you are borrorwing an emulator from HP-UX. And since xterm is an Xwindows program, you are either running an HP-UX graphics workstation or using a PC or Linux system to connect to your HP-UX system. This is a very different environment (due to the way Xwindows is normally configured) so your environment is severely truncated.

You need to use a 'normal' login where you get a login shell and a normal environment. If you must use Xwindows, then run this command:

echo "*loginShell: true" >> $HOME/.Xdefaults

on your HP-UX system. Then close your window and login again. This time, you will have a login shell and complete environment.
