[cod] Screen and su question.

[Steven Hartland]

LOL
Erm dont delete them /me slaps Jay around with some skills :P

They are owned by a different user as that's the user u logged in as.

Your "terminal" is always owned by the user u log in as. This is to prevent
other people reading your "screen".
What I suspect u really want to do is to create a server under screen
to do this use -m -d e.g.
su - coduo -c "screen -m -d <server command>"

Now if u want to login like u have and reconnect to see whats happening
you will need to give said user access to your "terminal". To do this
just use chown or chmod. Once your done dont forget to either:
1. undo the permission changes
2. logout totally and then reconnect ( u get a new "terminal" ).

    Hi Guys,

     

    With great joy I have read all the posts in this lists and most of the information is very valuable! Thank you all for that.

     

    Now, the time has come that I need some help. 

     

    I want to use screen to monitor my server and have created a script to start it. However, I have a problem with screen which I do not know how to solve. It's probably something trivial, but my UNIX knowledge is not so great yet so I am quite stuck. Below is a snip let of what I wanted to do and does not work.

     

     

    Using username "yuk".

    Authenticating with public key "imported-openssh-key" from agent

    [yuk at yoda yuk]$ su -

    Password:

    [root at yoda root]# su - coduo -c screen

    Cannot open your terminal '/dev/pts/6' - please check.

    [root at yoda root]# ls -la /dev/pts

    totaal 148

    drwxr-xr-x   2 root root      0 jan 11  2005 .

    drwxr-xr-x  25 root root 147456 jan 11 22:22 ..

    crw--w----   1 cod  tty  136, 0 jan 11 22:58 0

    crw--w----   1 yuk  tty  136, 1 jan 11 22:59 1

    crw--w----   1 root tty  136, 2 jan 11 22:53 2

    crw--w----   1 yuk  tty  136, 3 jan 11 22:59 3

    crw-------   1 yuk  tty  136, 4 jan 11 22:59 4

    crw--w----   1 yuk  tty  136, 5 jan 11 23:00 5

    crw--w----   1 yuk  tty  136, 6 jan 11 23:00 6

    [root at yoda root]# tty

    /dev/pts/6

     

     

    In bold, you can see that the screen command fails because it cannot open the /dev/pts/6 pseudo terminal. That is correct because that terminal is owned by the user YUK not the user CODUO which I have su'ed to before calling screen.

     

    If anyone can help me out I would really appreciate it.

     

    Kind regards,

    Yuk.
