known_hosts file

solarman

I use Linux on my home machine and playing around with servers trying to learn the workings of the different OS is fun. But every time I install an OS and go to login with my terminal I have to delete the old entry from my known_hosts file.

Is there anyway to not have the server listed in the file?

I understand but if I install a new OS on the IP when I go to login I cant until I delete the old entry from the file.

Can you post your output?

Or do you mean the rsa-fingerprint message

The authenticity of host '111.222.333.444 (111.222.333.444)' can't be established.
RSA key fingerprint is f3:cf:58:ae:71:0b:c8:04:6f:34:a3:b2:e4:1e:0c:8b.
Are you sure you want to continue connecting (yes/no)? >

This one comes every first login from the ip/host.

or just edit the sshd_config and add the following:

Host 192.168.0.*

StrictHostKeyChecking no
UserKnownHostsFile=/dev/null>

replace host with ur real network address
