Help with to check the tcp network connectivity between servers and hosts

ello,

i am new to the networking side.
I have a requirement to check the tcp network connectivity between server it's running on and the list of host's and ports combination.

please help me where i am going wrong.

my code:

Code:
#!/bin/bash
#read the file line by line

cd "$1"
cat testping.txt | while read line
do
        # check if there are no blank lines
        if [ ! -z $line ]; then
                            hosts=${line//:/ }
                                echo $(nc -z $hosts) >> testouput.txt
        fi
done

i think nc doesn't work, as i need to check the tcp connectivity.

testping.txt file contains

Code:
seattle01.iris2.local:1522
boston01-vip.iris2.local:1521
boston02-vip.iris2.local:1521


my output file should be

Code:
seattle01.iris2.local:1522|success |3.4s
boston01-vip.iris2.local:1521|success |0.2s
boston02-vip.iris2.local:1521|service not running|3.4s

please help me how to find this.
