How to set Subnet in a node which act as both server and client role?
Hi, Etienne
I took a look for the below host configuration parameter (IndirectData), the default is no. For the below example:
A ConnectTo B, B ConnectTo C:
If IndirectData = no (default), then A wouldn’t establish direct connection with C, but will be forwarded by B.
If IndirectData = yes, then A will try to establish direct connection with C, even though A don’t have the statement of

How to set Subnet in a node which act as both server and client role?
Hi, Etienne
In addition, is there any option or switch can turn of the automatic direct connection? For the example below, even A has the route to C and can establish UDP connection directly, but I need the traffic to go through B, how can I achieve that easily? (instead of remove something from A’s routing table, or manually block the connection between A and C)

Conflicting Default Values. A trusts B. B trusts EvilNode. Does that mean A trusts EvilNode?
*You should repeat this for all nodes you ConnectTo, or which ConnectTo
you. However, remember that you do not need to ConnectTo all nodes in the
VPN; it is only necessary to create one or a few meta-connections, after
the connections are made tinc will learn about all the other nodes in the
VPN, and will automatically make other connections as necessary. *
The above is from the docs. Assuming

Slow Speed
Hi,
I´m using Tinc for several years, but I didn´t fix a performance problem.
There a about 20 nodes in this network.
Master:
10.0.0.12 (dedicated host in a datacenter, debian, 100mBit port)
tinc.conf:
Name = TincKnoten12
AddressFamily = ipv4
Interface = tun
ProcessPriority=high
mode = router
#DirectOnly = no
Compression=0
PMTUDiscovery = yes
#IndirectData = yes
#ReplayWindow = 64

Performance issue with TunnelServer mode
Hi,
We have a tinc network of about ~200 hosts and in the full mesh
configuration we've had a lot of problems with the edge propagation storms
taking the entire network down. Recently we had a setup with a small number
of "hubs" to which all the other nodes connected to, which limited the
number of meta connections, but that didn't help much with the edge
propagation issues.

friend of a friend type darknets
Hi!
here a little patch for darknet functionality, i hope it does what its
intended for sufficiently ... but it seems to work :).
what should it do?
imagine your friend-network. A trusts B and C. B trusts D and E, D trust
F, C trusts G. All trust relationships are mutal
A <---> C <---> G

\-----> B <---> D <---> F

File locks?
Hello,
Recently, the following problem started happening with a particular samba
server:
If i have a file open for reading (say, a pdf in xpdf) and then try to write
to it (say, through recompiling a latex document) it complains that it
cannot open the file for writing.
this seems like a file lock issue but I am unsure where it is happening. My
previous usage should be perfectly safe since

static configuration
Hello,
I am tying to create tinc vpn for the ~1000 nodes and was thinking why meta connections are
needed at all if I only need static configuration where every node knows addresses of other hosts
and due to the amount of traffic any indirect connections will not work, so DirectOnly=yes is a must
and then passing around routing information is not needed, right? Currently I have 10 nodes

Metadata flooding
Hi,
we use a tinc network of about 400 nodes, all of them linux servers, partly
in different datacenters (but generally low latency). Usually this is
working very well (for weeks without a problem).

restarted a larger number of servers or when there was a connectivity issue

Tinc CPU usage
Hi, I'm using Tinc v1.0.11 on Ubuntu 10.04 and seeing high CPU usage (up
to 30%) on what I wouldn't consider high traffic levels.
The traffic is application server to database server connections and
multicast communication for session-replication on the application server.
I'm running the tinc daemons in switch mode, to support the multicast. I
have tried settings:

Missing connection
Hi,
I've set up Tinc in switch-mode on the three nodes "gw", "rb493g" and
"v900w", but the nodes "rb493g" and "w900v" do not connect to each
other.
On each node port 655 is opened with TCP and UDP.
"gw": static IPv4- and IPv6 address listed in the hosts-file "gw"

Lots of Flushing x bytes to y would block messages
We run tinc in a linux environment in which it sits there waiting for
connections from the clients. All clients are configured to only have one
ConnectTo which points to this server.
We're seeing in the server log that as soon as a client's connection is
activated, a whole bunch of "Flushing x bytes to that host would block" is
logged and the whole vpn is bogged down and has

Lots of Flushing x bytes to y would block messages
The server has a 1G symmetrical fibre line. It has been speedtested to
various local servers to be close to 800-900M. When there is only a single
client, there isn't much problem and as soon as the connection is made, the
ping time through to tunnel is a respectable 30ms. As soon as a few more
clients are connected, ping time degrades to hundreds and sometimes seconds
and with dropped packets.

IndirectData
Hi list,
I'm hoping someone can help me understand when to use IndirectData.
Quoting the manual:
IndirectData = <yes|no> (no)
This option specifies whether other tinc daemons besides the one you
specified with ConnectTo can make a direct connection to you. This is
especially useful if you are behind a firewall and it is impossible to
make a connection from the outside to your tinc

voice mesage converted into text message & send it to resp. email ids. is
this possible.
If yes. we can do the same with help of Asterisk or we require expertnal

Cache of the the unreachable nodes cause un-optimized route?
Hi, All
Here is the case:
A, B, C, D all configured with "IndirectData = yes”, so connection only happens when there’s a “ConnectTo” in tinc.conf.
Arrow indicate the “ConnectTo” direction
Everything works fine earlier as below:
1. A connect to C, D connect to C
2. C is the transit node where only forward traffic between A and C
3. D advertise 0.0.0.0/0#2
4. A can access internet from D
