Re: [Ssh-sftp-perl-users] Help using Net::SSH::Perl with automatic authentication

[Eduardo R. A. <er...@gm...>]

Well, permissions are O.K. on the keyfiles (600).
Yes, (home) is the redacted path to my home directory.
Under .ssh I have a known_hosts2 text file with the list of machines I
usually connect and their keys (I believe), this is present in all machines
I usually connect to. Also, under .ssh2 I have a hostskeys directory with
all .pub files from machines I usually connect to, this is also present on
all of them.
I also created DSA keys and I'm having the same issue.
So everything seems to be O.K. from what you told me and everything I've
researched. I'm totally lost about what else I can try...
