 Posted: Mon Jul 10, 2006 4:26 am Post subject: Auto-Login on certain ttys [SOLVED] |
 |
|
I hope this hasn't been asked before. I've recently started to do almost everything from the shells, rarely using X anymore. I was wondering if it was possible to have certain ttys log in automatically as certain users and start up certain programs. For instance, I want tty1 to start as user1, running screen with mocp and mc. Then I want tty2 to start as user1 running screen with tmsnc, pine, and elinks, and similar for tty3, etc... How can someone set that up?
Thanks,
Nathan

Example : Spawn a 2 Shells with user "Carl", one shell launchs top, and one shall watching a logfile:
Log in with your Username into the X-Server (Carl as example)
Put this in your Autostart ( from your WM ) :
xterm -e top&
xterm -e tail -f /home/carl/somelogfile.txt

Wow, fast reply. Sorry, I should've been more clear. I don't want to use X, at all. Like I want from boot to be logged in with screen with mocp and mc started in tty1 (Alt+F1), screen with tmsnc, pine, and elinks in tty2 (Alt+F2), etc...
Any Ideas?
Thanks,
Nathan |

nianderson,
No, I did not. And I really wish I could. I've googled it for a long time, checked other forums, can't find anything. And now I would like to have it more than ever, as I rarely use X anymore, and would like to have everything set up right at boot.
Sorry about that, maybe somebody has a solution.

Cheers,

I think you just need to edit your /etc/inittab and replace getty with what you would like to run. If you want to run something as a user then just make sure you stick su - username in front of it.
I think Im going to give that a shot today. I know its possible ive seen it on other setups.

Yep you just need to edit /etc/inittab
look for the first agetty line.
you need to emerge mingetty and then do something like this
| Code: |
1:12345:respawn:/sbin/mingetty --noclear --autologin username tty1
|
HTH

Alright, here's what I've got.
I haven't rebooted since installing mingetty, so I haven't tested that yet. But I'm trying to get certain things to execute when I log in, like screen and things like that.
So here's my .bashrc:
| Code: | | exec /usr/bin/ttytest |
and in /usr/bin/ttytest I have:
| Code: | function get_tty
{
if [ notset.$DISPLAY == notset. ]
then
ttyname="$(tty | sed -e 's/.*\([0-9]\)/\1/')"
fi
}
function startup
{
get_tty
if [ $ttyname == "1" ]
then
echo "tty1"
else
echo "not tty1"
fi
}
startup
|
I ran env-update, and source /etc/profile, just to be sure.
I did a chmod a+x to the file, and ran it in fluxbox. and sure enough, the output was "not tty1". which is what I expected. then I ran it in tty1. and the output was "tty1", again as expected. so in tty1, I logged out, then logged in again, and I got the standard:
| Code: | login(pam_unix)[8003]: session opened for user root by (uid=0)
Last login: Wed Sep 20 16:46:41 2006 on tty1
login[8002]: ROOT LOGIN on 'tty1'
localhost ~ # |
what am I doing wrong? should I put it in bash.profile? how can I fix this?
Cheers,
Nathan |

Nathan,
I use this to run hpl as a specific user on a tty as a node boots. Is this what your trying to do? Im sure you can replace that with a screen command and have a nifty screenrc that runs everything else.
| Code: |
c2:2345:once:/bin/su teamhpc /home/teamhpc/Linux_OPTERON_FBLAS/hpl-single.sh localhost

Alright, getting closer.
So in my inittab, I have:
| Code: | # TERMINALS
c1:12345:once:/bin/su root /root/screen1.sh tty1 linux
c2:2345:once:/bin/su root /root/screen2.sh tty2 linux
c3:2345:once:/bin/su root /root/screen3.sh tty3 linux
c4:2345:once:/bin/su root /root/screen4.sh tty4 linux
c5:2345:once:/bin/su root /root/screen5.sh tty5 linux
c6:2345:once:/bin/su root /root/screen6.sh tty6 linux |
and in /root/screen[n].sh I have:
| Code: | | exec /usr/bin/screen -c ~/.screenrc[n] |
then, in ~/.screen[n] I have:
| Code: | screen -t MAIL 0 pine
screen -t MSN 1 msn
screen -t GOOGLE 2 elinks http://www.google.com |
..or whatever I want to start in that session of screen. Yeah, I know it's really round-about, but after a ot of trial and error, it got me the closest to where I want to be. But now when I boot up, I get some messed up thing. First of all, it's all in tty1. Second, it's all messed up instances, sometimes they overlap a bit, and it's almost impossible to navigate between them. So, can somebody help me out? I'm sure someone will see a fault in my n00b attempt at writing configs. Thanks in advance, and thanks for all of your help so far.

You know I am doing something very similar. I have it setup a little different.
I have the user setup to login automattically in inittab
| Code: |
c1:12345:respawn:/sbin/mingetty --autologin root tty1
|
Then I have a .bash_profile that detects which tty the login was on.
| Code: |
# bash_profile
# Author: Nick Anderson
# This bash_profile launches the burn options menu
# if the users tty = 1. This allows us to only
# present the menu on the first login screen and
# only once ... as long as no one logs out of tty1
# and logs back in.
# Get current tty
TTY=$(basename $(tty))
echo "You are currently connected to $TTY"
if [ $TTY == "tty1" ]
then
#Execute Burnin Option Menu
/root/scripts/burn-menu
fi
|
then depending on the tty I launch another script see the Burnin option memu above. That basically is just a menu to select which screenrc to launch screen with. You could just stick your screen -c /path /to/config in place of the burnin option menu that I have above. See how that works out for you. |

Hey nianderson
That worked. Thanks a lot for your help. I edited your script to be:
| Code: | if [ $TTY == "tty1" ]
then
#Execute Screen
/usr/bin/screen -c ~/.screenrc1
fi
|
then to continue on:
| Code: | if [ $TTY == "tty2" ]
then
#Execute Screen
/usr/bin/scree -c ~/.screenrc2
fi
|
etc.
Thanks again for all of your time. It turned out really nicely.

Does 'mingetty --auto-login' mean that you won't be asked for password authentication anymore?

Yep just logs you in automatically, no questions asked. |
