<div dir="ltr">i need forwarding off , cause i need a central node , which is connected directly to all the network , directly , so it can usually upload content directly , without slowing down other nodes in the network , i also don't want it to act as a forwarder , since ,it only has 2mbps of bandwidth , and i don't want it for that purpose , <br>
is there any other way to fix this problem ?<br><br><div class="gmail_quote">On 16 March 2012 14:30, <span dir="ltr"><<a href="mailto:tinc-request@tinc-vpn.org">tinc-request@tinc-vpn.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

the thing is that , the node with forwarding off is connected to all hosts , directly with connect to , <br>
and seems like that for some nodes the shortest path , that the tinc network can find is through the node with forwarding off , <br>here are the results of my first ping to all my hosts with the host with forwarding off present : <br>
./monitorhosts <br>Host : 10.0.113.3 is down (ping failed) at Fri Mar 16 13:36:57 2012<br>Host : 10.0.128.3 is down (ping failed) at Fri Mar 16 13:37:43 2012<br>Host : 10.0.130.3 is down (ping failed) at Fri Mar 16 13:37:59 2012<br>
Host : 10.0.132.3 is down (ping failed) at Fri Mar 16 13:38:05 2012<br>Host : 10.0.138.3 is down (ping failed) at Fri Mar 16 13:38:34 2012<br>Host : 10.0.141.3 is down (ping failed) at Fri Mar 16 13:38:43 2012<br><br>
if i switch off the node with forwarding=off , the result is as follows :<br>
./monitorhosts <br>Host : 10.0.113.3 is down (ping failed) at Fri Mar 16 13:39:28 2012<br>which is flawless (don't mind 113) , <br>when i reconnect the node with forwarding=off , the result changes to the following :<br>
./monitorhosts<br>Host : 10.0.113.3 is down (ping failed) at Fri Mar 16 13:44:49 2012<br>Host : 10.0.141.3 is down (ping failed) at Fri Mar 16 13:46:06 2012<br>. :D<br>when i try to ping 10.0.114.3 i receive the following :<br>
ping 10.0.141.3<br>PING 10.0.141.3 (10.0.141.3) 56(84) bytes of data.<br>From 10.0.141.3 icmp_seq=1 Destination Net Prohibited<br>From 10.0.141.3 icmp_seq=2 Destination Net Prohibited<br>.<br>the tinc version is 1.0.16 , running on centos 5. <br>
if anymore information needed i'd be happy to help , <br>also i should mention that , i have no problem reaching the nodes from the node with forwarding off .<br>i have around 64 nodes in my tinc mesh , <br>i remember our previous admin told me that , when he made full mesh , (connectto to everwhere) , the network became unstable , is there a limit ? should we experience slowdowns or something as the nodes grow ?<br>
thank you.<br><br><br></div>

<br>
That is correct. And indeed with Forwarding = off, those packets are dropped,<br>
that is exactly what this option is meant to do. Why do you want to use<br>
Forwarding = off?<br>

<br>
64 nodes is not an unusual number for tinc. In what way does the network become<br>
unstable?<br>
<br>
> is there a limit ?<br>
<br>
There is no limit in tinc itself, but if you have slow network connections it<br>
can take a while for tinc to exchange metadata between nodes. If it takes too<br>
long, it might close connections. You can try to increase the value of<br>
PingTimeout in that case.<br>
<br>
> should we experience slowdowns or something as the nodes grow ?<br>
<br>
It should not be noticably slower, but if you have a lot of nodes joining and<br>
leaving all the time it might.<br>
