[Ssh-sftp-perl-users] known_hosts2

[Morgan S. <mo...@du...>]

I have a couple questions about the handling of known_hosts2.

I know that the location of known_hosts2 file is pretty standard, but is
there an option to specify where the known_hosts2 file resides?

Now for something different.  I've been having difficulties getting
scripts to work well with the contents of known_hosts2 as created by
Net::SSH::Perl in non-interactive mode on a machine with an empty
known_hosts2 file.  What I'm finding is that the first time I connect to
a host it's host key (ssh-dss) is added to known_hosts2.  Even after
installing Crypt::RSA gand clearing the known_hosts2 file,
Net::SSH::Perl still puts ssh-dss entries into the known_hosts2 file.
Not so great.  It seems as though ssh-dss is an unsupported key type
which is caught in an eval statement.  If I use ssh to login to the
remote host then an ssh-rsa host key is added to known_hosts2 by the ssh
program.  Hosts.pm likes ssh-rsa entries :-)

I know that ssh-dss entries are default, but if they aren't supported
why are they still added to the known_hosts2 file even though Crypt::RSA
is installed? I can see how dss may be prefered over rsa because
patents.  Is there a way to enable support for dss? Is there a module I
might not have installed?

I suppose I could specify that as an option:
my $ssh =3D Net::SSH::Perl->new($host, options =3D> ["HostKeyAlgorithms
ssh-rsa,ssh-dss"]);
to enable the behavior I'm looking for. It feels like I'm missing
something though, like there's a better way to do it.  Suggestions?
