<DIV><FONT face=Arial size=2>LOL</FONT></DIV>
<DIV><FONT face=Arial size=2>Erm dont delete them /me slaps Jay around with some
skills :P</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>They are owned by a different user as that's the
user u logged in as.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Your "terminal" is always owned by the user u log
in as. This is to prevent</FONT></DIV>
<DIV><FONT face=Arial size=2>other people reading your
"screen".</FONT></DIV>
<DIV><FONT face=Arial size=2>What I suspect u really want to do is to create a
server under screen</FONT></DIV>
<DIV><FONT face=Arial size=2>to do this use -m -d e.g.</FONT></DIV>
<DIV><FONT face=Arial size=2>su - coduo -c "screen -m -d <server
command>"</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Now if u want to login like u have and reconnect to
see whats happening</FONT></DIV>
<DIV><FONT face=Arial size=2>you will need to give said user access to your
"terminal". To do this</FONT></DIV>
<DIV><FONT face=Arial size=2>just use chown or chmod. Once your done dont forget
to either:</FONT></DIV>
<DIV><FONT face=Arial size=2>1. undo the permission changes</FONT></DIV>
<DIV><FONT face=Arial size=2>2. logout totally and then reconnect ( u get a new
"terminal" ).</FONT></DIV>
