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 ?

pg_transaction_status
PG_TRANSACTION_STATUS(3) PG_TRANSACTION_STATUS(3)
pg_transaction_status - Returns the current in-transaction status of the server.
SYNOPSIS
int pg_transaction_status (resource $connection)
DESCRIPTION
Returns the current in-transaction status of the server.
Caution
pg_transaction_status(3) will give incorrect results when using a PostgreSQL 7.3 server that has the parameter autocommit set to
off. The server-side autocommit feature has been deprecated and does not exist in later server versions.
PARAMETERS
o $connection
- PostgreSQL database connection resource.
RETURN VALUES
The status can be PGSQL_TRANSACTION_IDLE (currently idle), PGSQL_TRANSACTION_ACTIVE (a command is in progress), PGSQL_TRANSACTION_INTRANS
(idle, in a valid transaction block), or PGSQL_TRANSACTION_INERROR (idle, in a failed transaction block). PGSQL_TRANSACTION_UNKNOWN is
reported if the connection is bad. PGSQL_TRANSACTION_ACTIVE is reported only when a query has been sent to the server and not yet com-
pleted.
EXAMPLES
Example #1
pg_transaction_status(3) example
<?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
$stat = pg_transaction_status($dbconn);
if ($stat === PGSQL_TRANSACTION_UNKNOWN) {
echo 'Connection is bad';
} else if ($stat === PGSQL_TRANSACTION_IDLE) {
echo 'Connection is currently idle';
} else {
echo 'Connection is in a transaction state';
}
