Re: libssh session connection timed out error

[Aris Adamantiadis <aris@xxxxxxxxxxxx>]

Hi,

Are you sure that there is no firewall ?
Are you sure libssh does not attempt to connect on IPv6 which is not
supported by FreeSSHd ?

I would also advise you not to use FreeSSHd on a production system as it
has a known vulnerability and no public patch:
