Hi Folks,
This has been driving me nuts all day. I've been unable to google myself out of it. Maybe someone here can help? I followed the instructions from: http://www.tinc-vpn.org/examples/macbook-install/ Ubuntu server <-> Ubuntu server works just fine with the same config. Ubuntu server <-> Mac laptop not so much. The error I'm getting is: 2012-04-10 21:48:44 tinc.l3vpn[52621]: Error while writing to Generic BSD tap device /dev/tun0: Input/output error 2012-04-10 21:48:44 tinc.l3vpn[52621]: Error while writing to Generic BSD tap device /dev/tun0: Input/output error <lot of the same spew…> The error pops up after I try to get DHCP going over the link. (ipconfig set tun0 DHCP). Not that it works before I try and do that. Both sides seems happily connected before issuing the DHCP command. I've tried just about everything I can think of for the configs. Switch on, off, bridging on and off on the server side.. nothing seems to work. I do find it odd that under linux the virtual device looks like this: vpn Link encap:Ethernet HWaddr 4e:31:65:e7:32:f6 inet6 addr: fe80::4c32:66ff:fec6:32e7/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1034 errors:0 dropped:0 overruns:0 frame:0 TX packets:529919 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:87139 (87.1 KB) TX bytes:56253688 (56.2 MB) standard kinds of goodness. On the Mac side it seems slim on info: tun0: flags=8851<UP,POINTOPOINT,RUNNING,SIMPLEX,MULTICAST> mtu 1500 open (pid 57014) Makes me think that the tun/tap device is wonky? The Tun/Tap stuff I got from port as per the instructions. Configs: # cat tinc.conf Name = laptop Mode = switch # cat hosts/laptop Subnet = 10.20.20.0/24 Address = 10.20.20.38 -----BEGIN RSA PUBLIC KEY----- <blahblahblah> # cat hosts/server -----BEGIN RSA PUBLIC KEY----- <blahblahblah> I figure it's something very simple that I'm missing. Can someone save my sanity please? Thanks, -Matt
