로컬 네트워크에서 활성 SSH 키 테스트

SSH 키를 사용하여 LAN에서 아직 활성화된 SSH 서버를 찾기 위해 bash 스크립트를 완료하려고 하는데 다음 단계에서 멈췄습니다.

#!/bin/bash

# LAN SSH KEYS DISCOVERY SCRIPT

</etc/passwd \
grep /bin/bash |
cut -d: -f6 |
sudo xargs -i -- sh -c '
     [ -e "$1" ] && cat "$1"
' -- {}/.ssh/known_hosts |
cut -d' ' -f1 |
tr ',' '\n' |
sed '
     /^\[/{
          s/\[\(.*\)\]:\(.*\)/\1 \2/;
          t;
     };
     s/$/ 22/;
' |
sort -u |
xargs -l1 -- sh -c '
    if echo "~" | nc -q1 -w3 "$1" "$2" | grep -q "^SSH"; then
          echo "#### SUCCESS $1 $2";
    else
          echo "#### ERROR $1 $2";
    fi

# TIME TO TEST WHICH SSH servers are still active with the SSH keys
# AND THIS IS WHERE I AM FROZEN...
# Would love to have bash script that could
# ssh -l $users_that_have_/bin/bash -i $ssh_keys $ssh_servers
# Would also be very nice if it could save active
# SSH servers with the valid keys in output.txt in the format
# username:local-IP:/path/to/SSH_key

#!/bin/bash

# LAN SSH KEYS DISCOVERY SCRIPT
# TRYING TO FIND THOSE SSH KEYS NOW

cat /etc/passwd | grep /bin/bash > bash_users
cat bash_users | cut -d ":" -f 6 > cutted.bash_users_home_dir
for bash_users in $(cat cutted.bash_users_home_dir)
do
ls -al $bash_users/.ssh/*id_* >> ssh-keys.txt
done

# DISCOVERING THE KNOWN_HOSTS NOW

for known_hosts in $(cat cutted.bash_users_home_dir)
do
cat $bash_users/.ssh/known_hosts | awk '{print $1}' | sort -u >> 
hosts_known.txt
sleep 2
done
hosts_known=$(wc -l hosts_known.txt)
echo "We have $hosts_known known hosts that could be still active via SSH 
keys"

# TIME TO TEST WHICH SSH servers are still active with the SSH keys
# AND THIS IS WHERE I AM FROZEN...
# Would love to have bash script that could
# ssh -l $users_that_have_/bin/bash -i $ssh_keys $ssh_servers

ssh -l $users_that_have_/bin/bash -i $ssh_keys $ssh_servers이제 위의 bash 스크립트에 명시된 대로 작업을 수행 하고 활성 로그인을 덤프하는 방법을 찾으려고 합니다 .출력.txt파일 형식은 다음과 같습니다.

username:local-IP:/path/to/SSH_key

답변돕 고티논평:

이제 이것을 내 bash 스크립트에 통합하는 방법을 알아내려고 노력 중입니다. 이것은 나의 현재 시도입니다:

users=$(cat cutted.bash_users)
ssh_keys=$(cat ssh-keys.txt)

if ssh -l $users -i $ssh_keys $hosts_known -o BatchMode=yes -o 
ConnectTimeout=5
then echo $users:$hosts_known:$ssh_keys SUCCESS >> results.txt
else
echo FAILED
fi
