Script to locating Linux servers
All,
Need an urgent help! ,
I have an simple text file that holding more than 500 IP Address,
My requirement :
bash script that will run from my central server , and will scan with nmap all the 500 ip address , for ssh port with . for example with the command : nmap -sT | grep '22.*open'
After the scan, I want him to transfer output of any address he found that SSH port is open to another text file.
What will be the effective script?
Note, I do not want him to run on subnet, only on all the ip address that found on the file.
Thank you.

SSH-ARGV0(1) BSD General Commands Manual SSH-ARGV0(1)
NAME

[-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]
