Hello tincers, I was recently trying to add a new Windows client to my tinc network and ran into an interesting error; upon starting tinc I am met with the usual successful startup (debug level 0; detects TAP device; Ready), however it appears that any writes/reads from the TAP device fail with: "Error while writing to Windows tap device <device ID truncated>: (997) Overlapped I/O operation is in progress" A bit of googling doesn't reveal much except some possible intrusions by a couple of recent Windows KB updates. Is this some glaring failure of my own that I am just not seeing, or have the new updates incapacitated tinc in one way or another? Thanks! -- Adam Del Vecchio -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://www.tinc-vpn.org/pipermail/tinc/attachments/20141215/80027723/attachment.html>
You should mention your tinc version and the version of the "TAP-Windows Adapter V9" driver for the virtual network device you're using (i.e. the contents of "Driver version" as seen in the Device Manager).

You are almost certainly hitting this TAP driver issue: https://github.com/OpenVPN/tap-windows6/issues/3 There are two possible solutions: - Downgrade the TAP driver to the old version (the one provided with tinc) - Upgrade the TAP driver to the fixed version which is included in the latest OpenVPN installers at http://openvpn.net/index.php/download/community-downloads.html Note that I did not have time to test the new driver version so I don't know if it will work reliably (or even if it really fixes the issue). If in doubt, you should downgrade.

On Windows 8.1. Tap version: 9.0.0.21 Tinc: 1.0.25 It seems tinc is working (I can ping 3 other hosts on the network). But it seems it makes tinc a bit unstable, because the first few times it failed to run correctly(cmd hung after a huge load of those I/O errors). Regards, Tanel Liiv
