Sudo and ssh commands taking forever to work.

This just started happening today where my sudo and ssh (scp) commands onto my server are taking an exorbitant amount of time before they get "processed". ssh waited for a minute or two before request a password, and sudo had similar behavior every single time I used it.

This is my journalctl to my server for my scp command:

I also saw something about the hosts file possibly bogging down sudo, but my hosts file looks like this:

# Static table lookup for hostnames.
# See hosts(5) for details.

127.0.0.1 dogzenserver

Help would be appreciated.

Re: Sudo and ssh commands taking forever to work.

The computer crashed again recently. The problem disappeared. I'll just say the problem is solved, but this computer has been acting funny since december.

Address 127.0.0.1 is reserved for localhost connection, your hosts file should look like

127.0.0.1  localhost
a.b.c.d  dogzenserver

where a.b.c.d is real IP of dogzenserver

Re: Sudo and ssh commands taking forever to work.

You can link whatever domain you want and as many as you want to 127.0.0.1 (though many times you actually wanted to use 0.0.0.0) and it's esp. ok to have the localhost hostname there.

On topic: this could be all sorts of things, eg. sideload charging all CPUs or the IO of the host, network issues (physical, MTU, congestion, actually DNS resolution) but that's impossible to tell - notably from that not-journalctl snippet, that doesn't even have timestamps or the hostname and is completely out of context (is it the client or the server journal etcetc.)
