Delay during a SSH connection under Linux







When connecting to an SSH server, it takes a lot of time for logging (e.g, ssh server on Debian).

This is due to a problem from the name resolution of the server.

The server will try to use the name resolution mdns(part of the self-discovery/self-configuring network protocol of Zeroconf).


The delay is due to pending response of the mdns.

Solution 1


Disable Avahi daemon.
