It really isn't difficult to write such a robot, it just involves a port scan before actually probing. Using bash, something like: nmap $host | grep -i open

It really isn't difficult to write such a robot, it just involves a port scan before actually probing. Using bash, something like: nmap $host | grep -i open | cut -d '/' -f 1 | xargs -I {} ./sshscan.sh $host {} Where the contents of sshscan.sh is something like: #!/bin/bash nc $1 $2 | grep -i ssh if [ $? -eq 0 ]; then # ssh probing stuff here fi
