<div class="">Quick one for the below case, if node A have a direct
connection to node B, and node B have a connection to node X, then
I found node A will be able to talk to node X, but the
communication path is go through node B, instead of build direct
connection between A and X, is that right? I tested this in my
environment.</div>

<div class="">X-up is being called when any connection is being
built between node A and node X, it doesn't have anything to do
whether you have connectTo in the config file or not.
<div class="">Because tinc is a mesh network, if node A have a
direct connection to node B, and node B have a connection to node
X, you can have a connection between A and X, and X-up is being
called at the moment when it built a connection on
demand.<br class="">

<div class=""><span class="">Hi, Tinc Expert<br class="">
<br class="">
in my tinc.conf, the ConnectTo to host X is commented, like
below:<br class="">
<br class="">
#ConnectTo = X<br class="">
<br class="">
and there is a script: /etc/tinc/netname/hosts/X-up, I thought
commented the ConnectTo X wouldn’t trigger the X-up, but it
did.<br class="">
<br class="">
Why? What’s the logic behind to trigger host-up? How can I avoid
this except remove the host-up file?<br class="">
<br class="">
