tinc-1.0pre7-i386-1.tgz
Beste tinc-developer,
Ik moet van mijn baas een aantal VPN's aanleggen en ben nu thuis bezig om te
testen. Ik heb 2 computers in een thuisnetwerkje (totaal 6 computers)
geinstalleerd met SuSe 7.3, daar de klanten dit ook hebben. De computers zijn
verbonden met een switch.
Dit is de inhoud van mijn bestanden:
Op computer 1 genaamd suse met ip 192.168.0.99 netmask 255.255.255.0

Strange Traffic Problem
I'm been experiencing a very very odd problem for the past several weeks and
am throwing it out in case someone can shed some light on it for me.
There is a single box on our tinc mesh which can be pinged from all hosts,
but cannot ping any. It is not limited to ping, the box cannot communicate
over tinc. tinc is running in router mode for this mesh. ~30 other nodes
function normally,

Route certain trafic via a tinc node that is not directly connected.
Hello again :)
Thank you all for your reply's. Below are the config files of the 3 hosts.
I use tinc in router mode. I do not have a kernel mode config lines
anywhere so tinc must be using the default settings here.
I added the ipaddressx to subnets on hostc and this works. Traffic to
that ip is now routed via hostc.
But since this ipaddressx address changes often I need to resolve it

Packet capture to analysis the tinc connection close
Hi, All
Recently, one of my tinc client always suffer connection drop, I was suspect the connection was not stable to cause this issue, and BTW, I’ve set the PingTimeout to 10 seconds already, but this situation still happens a lot sometimes, but when the connection drop happens, the connection recovery pretty fast, normally in a minutes.
In order to deep dive into the cause, or proven the

I have configured the system as follow:
The LAN interface, of the two ADSL router, have address

Thank you for the helpful advice. We will try to group the servers with
different ConnectTo servers first. If this does not help we will look at
the TunnelServer solution. Just to make sure we understand TunnelServer
correctly: do you need to specify every host as ConnectTo that the host
should be able to communicate with or is it sufficient to just provide the
hosts files?
Thanks, Hendrik

Error: cannot route packet - please help
Hi,
I?m fighting with a silly problem: my syslog tells me tinc cannot route
a packet. I can use a telnet or the good ol ping, it is the same effect.
When I?m pinging from the laptop (172.16.11.2) the network address
(172.16.11.0) or any address numerically lower than the laptops address,
the packet gets routed, otherwise not. And when I ping the network
address, I get the reply twice, as to be

ARP resolution not done from one end
Folks,
We have a setup where each mobile node connects with 1 or more tinc instances (over different links) to a central node. tinc is running in switch mode. The link is chosen by setting the IP address on the active link's interface, and the central node sees this after the first packet on the link, and moves the MAC address to a different 'ethernet port' (link). This works really

book on tinc
Hi Ivo and Guus,
We are writing a book on building VPNs for Linux and a part of it describes
tinc. I wanted to make sure that your opinion, as tinc authors and
developers, is reflected.
First, let me ask a couple of technical questions.
1.
If there are two hosts, foo and bar, that are to be connected via tinc, and
each host should only have _one_ IP address (i.e. nmask is /32), would the

Multiple Tinc servers HA cross multiple regions
Hi,
I spend some time to investigate tinc to see how use it, Tinc is really
good.
I met some wired issue, maybe some guys can do me a favor.
In my case, there are 3 regions, and 2 servers in each region, total 6
servers.
each of servers will connect the servers in other regions, but no
connection to server in same region in configuration.
Region us-east
Region us-west
Region uk

Does the INT signal will force the tinc to re-read the tinc.conf file
I mean, if I changed pingtimeout on tinc.conf, -kHUP will force the tinc to re-read that parameter into effective? If no, any other ways to make it effective other that kill the process?
for tinc 1.0.
