Created Unassigned: ssh with IPv6 address not working under Linux (help with example?) [2714]

Hallo,

I couldn't figure out how to use your SSH library with an IPv6 address under linux (Ubuntu 15.04),
however it works perfectly fine with an IPv4 address.

my code looks like this:

```
IPAddress ipAddress = IPAddress.Parse ("fe80::XXXX:XXXX:XXXX:XXXX");

SshClient sshClient = new SshClient(ipAddress, user, passwd);
sshClient.Connect();
SshCommand sshCmd = sshClient.RunCommand(command);
sshClient.Disconnect();
```

I hope you can reproduce this issue and/or provide me a code example.

Best regards,
wima
