remsh and login messages

Scott E Smith — Wed, 24 Jul 2002 18:02:52 GMT

I am doing an su from root to another account and issuing a subsequent remsh command. ALl of the output is being re-directed to a file but the file is full of the information in the /etc/copyright file. Is there any way to avoid this? Thanks.

Yes and no. Yes you can zero out the copyright file. I'd recommend backing up the old one for possible legal reasons. I.E.
cp -p /etc/copyright /etc/copyright_orig
cat /dev/null >/etc/copyright

FYI it is not the "su" causing the problem, but the remsh. If no session is established in recex, rsh, rlogin then the /etc/copyright and /etc/motd are displayed as this becomes a login session.

Shannon

Do you want to disable the copyright info for all users?
To do that in /etc/profile

comment out /etc/copyright.

#cat /etc/copyright

Might then there be a better way than remsh? I tried rexec but it requires a password.

.: check the difference between :
# su - username
AND
# su username

You could fgrep -v -f /etc/copyright outputscriptpath

This is a very common problem. /etc/profile and .profile must be rewritten to bypass terminal-specific code. That's because cron jobs and remsh's do not have a controlling terminal. Thus, commands that are appropriate for an interactive login must be bypassed when there is no terminal.

To determine whether this session is interactive, you can use:

if [ -o interactive ]
then
export INTERACTIVESHELL=/sbin/true
else
export INTERACTIVESHELL=/sbin/false
fi

Now when a command such as ttytype or tset or the copyright message appears, run these commands only when INTERACTIVESHELL is true:

if $INTERACTIVE
then
eval $(ttytype -s)
fi

And here's a solution for the long copyright message:

# This meets legal requirements...without the long message

if $INTERACTIVE
then
echo "\nThe copyright notice can be read by typing: cat /etc/copyright\n"
fi

Now, the message won't appear at all if the shell is not interactive and if it is, only the one-liner will be shown.
