Tox-Sync

A bot that sync messages between IRC and Tox NGC group chat.

Hard Forked

Hard forked from https://github.com/aitjcize/tox-irc-sync and changed to use the Python wrapping from https://git.plastiras.org/emdee/toxygen_wrapper. Just clone that repo and put the resulting directory on your PYTHONPATH.

Usage

Run: tox-irc-sync.py --help for command line arguments.

  --group_ignore GROUP_IGNORE A PK to ignore by the group

Examples

The general idea here is to use this to create a profile, and that profile will have one user, and one group to start with. That profile will contain the founders keypair for the group, so protect the profile as it contains the group's secret key.

Then you use this profile to invite yourself to be a moderator, by providing the your public key of the device you want to use to moderate the group with the ---group_moderator cmdline arg.

For the #tox group on libera.chat:

python3 tox-irc-sync.py \
	--nodes_json $HOME/.config/tox/DHTnodes.json \
	--irc_chan "#tox" --irc_host irc.libera.net --irc_port 6667 \
	profile_that_will_get_the_group_key.tox

Libera will not work over Tor, but irc.oftc.net#tor will:

python3 tox-irc-sync.py \
	--nodes_json $HOME/.config/tox/DHTnodes.json \
	--irc_chan "#tor" --irc_host irc.oftc.net --irc_port 6667 \
	--proxy_type 2 --proxy_host 127.0.0.1 --proxy_port 9050 \
	profile_that_will_get_the_group_key.tox

ChangeLog

• changed to use the Python wrapping from https://git.plastiras.org/emdee/toxygen_wrapper
• tox_irc_sync does SSL now.

Future Directions

1. It's intended as a IRC->Tox NGC gateway but it could work the other way round.
2. It could be a plugin under https://git.plastiras.org/emdee/toxygen which would broaden the range of callbacks that could be supported.
3. It could be a gateway to an existing NGC group with an invite bot.

Updates

Although Tox works over Tor, we do not recommend its usage for anonymity as it leaks DNS requests due to a 6-year old known security issue: https://github.com/TokTok/c-toxcore/issues/469 Do not use it for anonymous communication unless you have a TCP and UDP firewall in place.
