> SSH connections (either password auth, or private key auth) are not working on hosts where FIPS mode is enabled. If FIPS mode is disabled, the connections start working again.
>  
> The problem seems to be that libssh2 negotiates to use non-FIPS-compliant key exchange algorithms or ciphers, and then OpenSSL refuses to use them.
> The answer is most likely to just specify a list of FIPS-compatible algorithms and ciphers before connecting, if FIPS mode is enabled. It's unclear why libssh2 isn't already doing this.
