How to Disable password prompt during ssh login with key failure

How to Disable password prompt during ssh login with key failure

I wanted to login to a bunch of servers and test whether I could get in, or if I got error messages.

After messing around a while, I worked it into:

for n in `cat allhosts.txt`; do echo "host: ${n}"; ssh -oConnectTimeout=2 -oKbdInteractiveAuthentication=no -oPasswordAuthentication=no -oStrictHostKeyChecking=no -oChallengeResponseAuthentication=no myuser@${n} echo '----------'; done
