Tinc Clients Disconnecting
Hi,
Can you help me explain some behaviour please? I've 2 tinc clients that
happen to be on the same network and behind the same NAT gateway.
They've been working for ages. Without anything changing, they've
stopped. They both died, in sequence while I was actively connected to
them and using an SSH session.
When I check the logs of another tinc node they connect to I see

How to diagnostic UDP discovery failed situation
I found the server(1.1.1.1) didn’t receive the MTU probe from client, so I add iptables -A INPUT -p udp —port 443 -j ACCEPT.
After this, I see one packet matching on the server side, and the MTU negotiation works, but when I tear down the tinc, and re-establish the tinc connection, the counter of below UDP/443 never increase, and also my other tinc nodes never add this statement on iptables, but

How to diagnostic UDP discovery failed situation
Hi, experts
for example, the below case:
You can see a lot of back and forth MTU probe packets been exchanged between tinc nodes, but it’s weird that, from the debug log, one line shows "No response to MTU probes from node1”, but it indeed received a lot of MTU probe response, and finally it get the conclusion of "Packet for node1 (1.1.1.1 port 443) larger than minimum MTU”.

What/why this event happens: Can't write to Linux tun/tap device (tun mode) /dev/net/tun: Input/output error
Hi, Guus
Thanks a lot for your suggestion, actually I did something else as below.
But one question here is if I don’t add "/sbin/ifconfig myvpn 10.0.0.1 netmask 255.255.255.0”, it seems the crontab wouldn’t trigger tinc-up, and then the ip addr of myvpn wouldn’t be configured, then it will prompt the error of "Can't write to Linux tun/tap device (tun mode) /dev/net/tun:

What/why this event happens: Can't write to Linux tun/tap device (tun mode) /dev/net/tun: Input/output error
Hi, All
Due to some routing rotation purpose, I use crontab to add below info:
0 * * * * echo Subnet = 54.169.128.0/17 >> /etc/tinc/myvpn/hosts/aws_sgp
0 * * * * echo Subnet = 54.169.0.0/17 >> /etc/tinc/myvpn/hosts/aws_sgp
1 * * * * /usr/sbin/tincd -n myvpn -k

A FAQ: is it mandatory to include the local IP address classes in the global VPN address class?
Hello,
Since the present tinc documentation is not very clear about this, please
explain the following: is it mandatory to include the local IP address
classes in the global VPN address class?
Namely, please consider the following setup (which works great in practice):
1. A tinc VPN, full mesh, with n nodes (n > 3)
2. tinc runs on the firewall, which is also the default gateway for each

Sending METAKEY to db1
It looks like it's communicating properly but there is a problem with your
keys.
Can you rename and regenerate your keys?
On a project I'm working on when we transferred our keys to another client
it put Carriage returns so there was a key mismatch.
Try that and

I think, you do not need to specify "Device".

I've got a relatively simple tinc setup.
I've got two "servers" that are on the public internet that act as
routers for three "clients" that are behind NATs.
Those servers are called aaaaa and bbbbb the clients are xxxxx, yyyyy and zzzzz
Unfortunatly the servers have problems accepting a connection from the clients

Tinc 1.1pre15 double-crash
Hello,
this morning I apparently had tinc crash on me.
In 2 independent tinc clusters of 3 nodes each (but located in the same datacenter), one tinc process crashed in each of the clusters.
One process apparently with `status=6/ABRT`, the other with `status=11/SEGV`.
Interestingly, they crashed with only 5 minutes difference.
The only thing I can come up with that might explain this correlation

Yes, I am sure but added another broader rule:

same result for debug example.

Telnet will only do tcp not udp which tinc works on. Are you sure udp 655 is open?

Authentication scheme
Hello everybody,
Here are some thoughts about the authentication scheme to be used in tinc. The
current scheme (see CVS version, revision CABAL) does this:
Client Server
---------------------------------------
send_id(u)
send_challenge(R)
send_chal_reply(H)
send_id(u)

How can I change the speed of tun interface?
Hi, experts
I found the tun0 is 10Mb/s and I installed vnstat to monitor the tinc vpn traffic statistic, but due to 10Mb/s, the vnstat couldn’t update it’s database due to low speed rate, so anyway to change the tun from10Mb/s to higher?
[root at box1 ~]# vnstat -u
Info: Traffic rate for "myvpn" higher than set maximum 10 Mbit (248->341, r735 t38), syncing.

strange tinc error with many nodes
Hello,
we currently set up a large tinc network with 2 central Nodes (these nodes connecting to each other).
All satellites (ca 40) connect to these both machines. All containing two ConntectTo fields (for backup)

Name = nfp_hy
Device = /dev/tun
PrivateKeyFile = /etc/tinc/nfp_hy/rsa_key.priv
ConnectTo = nfp_f_vpn
ConnectTo = nfp_c_vpn
