How to check if any user is login to CVS

If User has a password on server and repository is using pserver and using ssh for login.
Assuming the repository is using pserver (you really should use ssh)

export xorpw=`grep "$CVSROOT" ~/.cvspass |awk '{print $3}'`
if [ "$xorpw" != "A" ]
then
LOGEDIN=true
else
LOGEDIN=false
fi
echo $LOGEDIN


With SSH
Assumption
A) $CVSROOT does not have a FQDN
B) hostname on the server does not return a FQDN
C) no username in $CVSROOT
or
D) both $CVSROOT and hostname will give you the same FQDN

If the above assumptions are wrong then script around them

MACHINE=`echo $CVSROOT |awk -F: '{print $3}'`
FROMMACHINE=`ssh $MACHINE hostname 2>/dev/null`
if [ "$FROMMACHINE" == "$MACHINE" ]
then
LOGEDIN=true
else
LOGEDIN=false
fi
echo $LOGEDIN
