should probably be
inet_ntop(AF_INET6, (struct...

I was just taking a quick look at the code, I'd make a pr otherwise.

hi.

why there is no sigmavpn dir under /usr/local/lib/?

The configure file in my server

I try the local_interface like /dev/tun /dev/tun0,but all failed
There is a openvpn service running at my server
The output of the ifconfig of openvpn is

Can't compile the master, considered creating a stable branch?

I suggest to add the key word "const" to the type specifiers for parameters like the following.

• protoname (function "loadproto")
• intfname (function "loadinterface")

Would you like to apply the advices from an article to more places in your source files?

Could you add a short description, screenshots and link to your website (if available) here on GitHub so that the use cases and target groups of your project are easily accessible to anyone coming to this GitHub page for the first time?

Many people use PPPoE as WAN. We get different IPs each time we connect PPPoE. On client side we often set bind to 0.0.0.0 to automatically let the socket choose outbound IP. ISPs may disconnect the link every few days. After reconnecting, we got a new IP. At that time, the socket created for the old outbound IP is no longer available.

We'll receive an error when writing to UDP socket:

Local write error -1: Permission denied

Then SigmaVPN exits. I think we should not exit here; we can close the old socket and create a new socket.

This problem can be bypassed by setting SigmaVPN to bind LAN IP like 192.168.1.1, which does not change, and let NAT do the IP mapping work. But still I think an extra NAT is not necessary if SigmaVPN can re-create sockets automatically.

I have configured as googlecode wiki said but always get error "Cannot assign requested address".

kernel: 3.14.3
config:

[test]
proto = nacltai
proto_publickey = xxxxxxxxxxxxxxxxxxx
proto_privatekey = xxxxxxxxxxxxx
local = tuntap
local_interface = sigmavpn
local_tunmode = 1
peer = udp
peer_ipv6 =0
peer_remoteaddr = 10.8.1.1
peer_remoteport = 995
peer_remotefloat = 1
peer_localaddr = 10.8.0.1
peer_localport = 995

It seems that you have neglected to actually check the nonce.

Hi,

Just compiled sigmavpn, but it complains about a missing config file:

root@d695d04bdc19 /root/sigmavpn/sigmavpn [169]# ./sigmavpn
SigmaVPN.
Copyright (c) 2011 Neil Alexander T. All rights reserved.
Configuration file '/usr/local/etc/sigmavpn.conf' could not be parsed

Do you have any example of a decent config file?

HI is there openwrt package for sigmavpn?

and windows support ?

thanks,
LP

Hello sir can u give me sample configuration of client and server.Thank you
