Full Discussion: Find active SSH servers w/ ssh keys on LAN
Top Forums Shell Programming and Scripting Find active SSH servers w/ ssh keys on LAN Post 303025446 by syrius on Friday 2nd of November 2018 01:33:01 PM

What is not working is this part exactly:

Code:
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 $users:$hosts_known:$ssh_keys FAILED >> not-active.txt
fi

You can see what it should do but actually my syntax seems incorrect because nothing gets into the file results.txt & not-active.txt.

You can see below the output I am getting when launching the bash script:

Code:
root@blackb0x:/home/sirius/TEST# ./TEST3.sh
We have 6 hosts_known.txt known hosts that could be still active via SSH keys
ssh: Could not resolve hostname sirius: Name or service not known
root@blackb0x:/home/sirius/TEST# ls
bash_users  cutted.bash_users  cutted.bash_users_home_dir  cutted.ssh_keys.txt  hosts_known.txt  not-active.txt  ssh-keys.txt  TEST3.sh
root@blackb0x:/home/sirius/TEST# cat not-active.txt
root sirius postgres:6 hosts_known.txt:/root/.ssh/id_rsa /home/sirius/.ssh/id_rsa /var/lib/postgresql/.ssh/id_rsa /var/lib/postgresql/.ssh/id_rsa.pub FAILED

Seems like I have a syntax error in my bash script...
