Hi there
it works great on Windows/Linux/iOS ...
Ist there support for Android? I couln't find any packages or build docs.

Thank you for help.
Greetings

The password is indeed not shown in argv, but for the better security that might be beneficial.

There are workarounds for not storing commands in bash_history and not using clear text passwords in scripts, but that still will be useful.

Hello.

I would like to use hans client on Windows. I've already test in server with openSuse and client with openSuse too, and it works fine, ping works between client and server.

Now I'm running windows client. I've installed TAP Driver and it's selected by hans. In fact when I run hans -c SERVER_IP -p xxx the TAP Adapter gets a valid IP addres like 10.0.10.101. But when try to ping to 10.0.10.1(Server addres) it doesn't work.

When I see log on my server it says: hans connection established: Cliente_IP.

But I noticed tha the TAP Adapter always says unppluged cable.

I'm using Windows 7 32Bits, runing hans as administrator.

Any ideas to make it works?

Thanks.

Hi,

I wonder how much bandwidth we got max, for tunneling IP over ICMP, as we see tunneling IP over DNS is very very slow.

the connection is not created, requests from the client is transmitted and arrive ok but back does not.
what can be the cause? thank you

ping from client to server are successful

Server:

Client:

I have to use NAT to pass a subnet through the tunnel.Adding site-to-site support would be great. BTW thanks for your great work.

Hi i am testing hans on windows 7 and i have the issue on the screeshot below :

any help please.

Would you please explain how to initialize an OpenVPN on top of hans?

this->device[VTUN_DEV_LEN] = 0;

sets the 20th element to 0 but its zero based so its past the end of the array.

Should read

this->device[VTUN_DEV_LEN-1] = 0;

Hello.
Not dropping other groups might leave the new process with some unwanted groups inherited.
I would recommend adding following patch:

I have downloaded hanstunnel in cydia. I can see that the info advises that it is a "background app", but I can still not figure out a way to configure hanstunnel.

I've even tried ssh'ing into my iphone, but I still cannot find an executable.

Please advised how I can setup my iphone to use hanstunnel.

Hi,

I would like to have more info on how to compile the hans code (branch "cygwin") on windows.
I downloaded cygwin with gcc-c++ and make, but then I do the .exe compiler through the cygwin terminal, if I execute it, I get:
"Error while starting application (0xc000007b)".

What should I do?

Thanks!

Some years ago upstream net-tools changed ifconfig to live in /bin: ecki/net-tools@36b541c

Of course, many distros continue to put it in /sbin/, but not all.

Moreover, in some distros such as RHEL/CentOS since at least 7.x, ifconfig is not even included in a base install, only ip and the like.

I've got some simple hacks to osflags and tun.cpp to handle alternate ifconfig paths at compile time, much like ac0d27e#diff-2fc819de3e4f16d2b86d4cc7bcb7042e739f76193d7de454488cb4b33fea848d for android support.

But I think better still would be some runtime selection/fallback. One could easily compile hans on a CentOS 7 system that has optional ifconfig installed, then bring the binary to a system that has only ip and find a nasty surprise.

There is some bug while handling multiple clients. The latest release of hans is running on Debian 7.7 server with that command:
hans -u nobody -s 10.5.2.0 -p ........

Then I run hans on windows 7:
hans.exe -c [MYSERV] -p ........ -q -f -a 10.5.2.34
and having no problems, 10.5.2.0/24 is visible and I am able to access the proxy IP at 10.5.2.222

After that I turn on my laptop with windows 8.1 and run hans on it:
hans.exe -c [MYSERV] -p ........ -q -f -a 10.5.2.70
It gives an output error: 2 [main] hans 3624 find_fast_cwd: WARNING: Couldn't compute FAST_CWD pointer . Please report this problem to the public mailing list [email protected] (I suppose this error is unrelated to the main issue, but please just keep it in mind too)
Though it connects normally. After that the windows 7 machine is losing connectivity with the 10.5.2.X network, I can't ping any address, on win8.1 neigher.
But if I disconnect windows 7 machine and reconnect 8.1 machine, I am able to access the net.

Resuming:

• They can't work constantly, looks like some broadcasting failure between the clients , meanwhile when there is only 1 connection it works fine.
• Issue persists if I remove -a and let hans assign IPs automatically
• both machines have the same WAN ip (connected to the same WIFI AP)

  UPDATE 1.1
  Just found out that if I connect them from the different WAN ip's this problem disappears. I confirm that the issue persists when connecting 2 different machines from the same external IP. Is there any workaround for it?

Now it's 2022, can I install this so that I get a tunnel between the server (linux) and my machine on windows or linux?

Mac OS Sierra,

freshly compiled from master,

sudo ./hans -c myhost.com -p mypassw
./hans[26398] : could not create tunnel device: No such file or directory

Thank you!

Hi,

I keep receiving the following message from the Windows client when trying to connect to a server that is running hans as well.

hans: error sending icmp packet: No route to host

This message is repeated 34 times and then the output stops. Is this a bug with the Windows version? or did I miss something while setting up hans? Here's the full output I receive

hans: opened tunnel device: Local Area Connection 2
Ok.
