How to report crash issues?

• Learn to use GDB (or see Arch Wiki if you can't stand seeing the Ubuntu logo)
• Preferably, build tuntox and c-toxcore from source
• run tuntox with -d -d -d switch (yes, three times) on both sides (client and server)
• Try reproducing the problem
• Type backtrace full in gdb console when it crashes
• Paste full debug output including gdb output in your issue. Don't forget to paste log from the other side (eg. from a client when you're reporting a server crash).
• Describe exactly how you reproduced the problem. Preferably try reproducing it again.

How to report non-crash issues?

• Make sure you're running the latest version
• run tuntox with -d -d -d switch (yes, three times):

tuntox -d -d -d -i ABDE4CF4541C27DBE36A812FF6752F71A9F44D1CF917CE489B30CC3D742500039B86C14F85F9

• Try reproducing the problem and note approximate date/time of the problem, so that logs can be cross-referenced
• Depending on the nature of the problem, logs from both server and client may be needed
• Describe exactly how you reproduced the problem. Preferably try reproducing it again.

Why is my connection slow?

The actual p2p connection is made by the c-toxcore library. The way it works is: it tries to establish a direct connection between peers and falls back to TCP relays if that's impossible.

The direct connection code doesn't see much work and c-toxcore sometimes uses a TCP relay even when both peers have a public IP address and can reach each other directly.

Also please note that sometimes the connection improves after a few minutes as the peers discover each other.

You're going to get the best connection if you see the following message on the client:

2018-03-24 08:59:21: [INFO]     Friend request accepted (An UDP connection has been established)!

The connection is likely to have worse latency when you see the following:

2018-03-24 08:57:21: [INFO]     Friend request accepted (A TCP connection has been established (via TCP relay))!

There's, however, a chance that it will upgrade to UDP after a few minutes:

2018-03-24 10:17:06: [INFO]     Friend connection status changed to: An UDP connection has been established

I have a direct UDP connection. Why isn't my connection faster?

Wait until https://github.com/gjedeer/tuntox/issues/41 is implemented. This change should improve speed and latency in the 10 Mbit/s+ range.

Can I run it with Docker?

I've made a Docker image by bundling a static build with Alpine Linux, but I don't think I'm going to remember to keep it up to date at all times. There's a Dockerfile and docker-compose.yaml.

The tox config is stored in /data and that's where you want to attach your volumes.

docker run -e 'TUNTOX_SHARED_SECRET=myassfeelsweird' -v /tmp/tt:/data -it registry.gitlab.com/gjedeer/tuntox:latest

The binary is in /usr/bin/tuntox (and /usr/bin/tokssh):

docker run -e 'TUNTOX_SHARED_SECRET=myassfeelsweird' -it registry.gitlab.com/gjedeer/tuntox:latest /usr/bin/tuntox -i 1234abc -p

Can I run it on Windows?

There's no native Windows version but, in the spirit of "just use Wine" answers, try the following:

• Why don't you install Docker for Windows and use the Docker image in Linux Containers mode?
• Windows Subsystem for Linux works with tuntox binaries too (see Releases tab on Github). To use the smallest amount of disk space, use Alpine Linux instead of Ubuntu (but it works on both). screenshot

Is your website a joke?

You're a joke for not using NoScript.
