title: Connecting without Host Key Error
tags: net ssh

To do a one-time connect without errors: 
```bash
ssh -o StrictHostKeyChecking no -o UserKnownHostsFile=/dev/null <hostname>
```
(I have a machine usually running Kubuntu that I sometimes boot into Windows,
so encounter host key check failures when ssh'ing to Windows.)
(Answer from a comment [on this askubuntu](https://askubuntu.com/questions/87449/how-to-disable-strict-host-key-checking-in-ssh))

or put in `.ssh/config`
```
Host b
  HostName binky
  StrictHostKeyChecking no
  UserKnownHostsFile=/dev/null
```

Note, **only do this on a LAN where security isn't an issue**.
