lots of disconnected things here...

telnet fails to connect probably because Fedora never installs telnet
server by default - use ssh for that.

seems as though ntpd reached the server (looks like a clock.redhat type
address)

avahi is for multicast and you probably don't need that so for now
ignore it.

openvpn for network manager, I'm assuming is an extension to allow you
to use network manager to up/down VPN connections as a user which makes
sense but isn't at all related to what you are trying to do.

network manager is the desired product for most if not all wireless
network connection management so don't remove it.

If you can ping back and forth, between the two machines, what exactly
is the problem?
