I'm running Ubuntu on my work PC, and my work place provides me with a
static IP address but not with a domain. It's sometimes useful for me to connect to that PC through ssh, but it's not common enough for me to instantly remember the
IP number. So I set um a dyndns account, and associated a short and intuitive domain name to that
IP.
Here's my question, when I try to ssh to the domain, it asks me
$ ssh
[email protected]
The authenticity of host 'something.there.foo (xx.xx.xx.xx)' can't be established.
RSA key fingerprint is 'ALPHANUMERIC STRING'
Are you sure you want to continue connecting (yes/no)?
That surprised me a little bit. I have already registered the RSA fingerprint by connecting directly to the
IP address. I thought the domain name was simply a convenient way of pointing me in the right direction (i. e. the
ip address), but that message makes me think my data is actually going through their servers or something.
Which one is it? Am I sending my password through someone else's server? Or is ssh just really really careful, thus warning me even if the final destination is a know host?
The ssh server I'm using is the openssh-server package.
