Check SSH Connection .. help ..
I've script where i check connection to many hosts ... it take input from HOSTLIST.txt
Ex. cat HOSTLIST.txt
host1
host2
while read HOSTNAME
do
echo $HOSTNAME
ssh -o "BatchMode=yes" ${HOSTNAME} "echo 2>&1" $$ echo flag=0 || flag=1;
if [ $? -ne 0 ]; then
echo "No SSH Connection" >> ${LOG}
else
echo " SSH Connection Good " >> ${LOG}
fi
done < HOSTLIST.txt
Problem is it processes host1 successfully and breaks before even it checks for host2
+ read HOSTNAME
+ ssh -o BatchMode=yes host1 echo 2>&1 2701 echo flag=0
2701 echo flag=0
+ [ 0 -ne 0 ]
+ echo SSH Connection Good
+ 1>> logfile.log
+ read HOSTLIST.txt
this is all i get from set -x mode ....
any ideas why its breaking ?
