Hi Tinc Mailing-Group, Having set up the kernel correctly, and got tinc running successfully, I am now trying to get two VPNs running at once. Hence I need to have two ethertap devices ( /dev/tap0 and /dev/tap1 ). The first tap0 device was created thus: mknod -m 600 /dev/tap0 c 36 16 chown 0.0 /dev/tap0 The second tap1 device was created too: mknod -m 600 /dev/tap1 c 36 17 chown 0.0 /dev/tap1 I am running a Linux 2.2.18 kernel, and the following lines have been added...

Hi, I recently had a machine filling up its harddisk with syslog and tinc pilling up milions of messages like this: "Error while reading from Linux ethertap device /dev/net/tun: File descriptor in bad state" I remembered that there was a difference between rsyslog and other loggers, where one of those was skipping those messages, and simply was displaying: "this message has been repeated x times" Any idea which logger it was? Best,...

...ress is correct) I got this on both hosts, but I deleted the line on the listening host so the problem is only left on the host that should connect ;-) Anyone that knows what this could be? (Kernel=2.4.16, tincd=1.0pre4) A other small question I have is; is it possible to use the "old" Ethertap instead of the universal TUN/TAP by just compile it into the kernel and create the /dev-files? I can't recompile tincd and I get the "File descriptor in bad state"-error when trying to use the universal TUN/TAP. Thanks! Best regards, Lars Fredriksson ----- Lars Fredriksson (mailto:...

Hello everybody, I have just released tinc 1.0pre4. Changes: - New authentication protocol (better security, and faster too). - TCPonly and IndirectData are back (but not fully tested). - Documentation revised, it's really up to date with the released package now. - tincd -K now stores public/private keys in PEM format, but keys of 1.0pre3 can still be used. - Faster and more secure

I fairly new to Linux, and I'm trying to set up Tinc on my Linux box. However I got stuck at the following point in the documentation: ".... The actual setup of the ethertap device is quite simple, just repeat after me: ifconfig tap_n_ hw ether fe:fd:00:00:00:00 ... ". Now, this is obviously not what I have to type to the command prompt, although, I'm not ashamed to say, that I tried this, too. These are the commands that I also tried: ifconfig...

It's your network, you can choose whereever you want to run tinc. As long as you make sure everything is routed correctly. If the firewall has the ethertap module, tinc can use that as well. -- Met vriendelijke groet / with kind regards, Guus Sliepen <guus@sliepen.eu.org> -------------- next part -------------- A non-text attachment was scrubbed...
