# PyLink FAQ
|
|
|
|
## Startup errors
|
|
|
|
### I get errors like "ImportError: No module named 'yaml'" when I start PyLink
|
|
|
|
You are missing dependencies - re-read https://github.com/GLolol/PyLink/blob/master/README.md#installation
|
|
|
|
### I get errors like "yaml.scanner.ScannerError: while scanning for the next token, found character '\t' that cannot start any token"
|
|
|
|
You must use **spaces** and not tabs to indent your configuration file! (`\t` is the escaped code for a tab, which is disallowed by YAML)
|
|
|
|
## Linking / connection issues
|
|
|
|
### PyLink won't connect to my network!
|
|
|
|
As a general guide, you should check the following before asking for support:
|
|
|
|
1) Is the target network's IRCd showing failed connection attempts?
|
|
- If not:
|
|
1) Is PyLink connecting to the right port (i.e. one the IRCd is listening on?)
|
|
2) Is the target network's IRCd actually binding to the port you're trying to use? If there is a port conflict with another program, the IRCd may fail to bind but *still start* on other ports that are free.
|
|
3) Is the target port firewalled on the target machine?
|
|
4) Is there a working connection between the source and target servers? Use ping to test this, as sometimes routing issues between providers can cause servers to become unreachable.
|
|
- If your servers are purposely blocking ping, it's up to you to find another solution to test this! 😬
|
|
|
|
- If so:
|
|
1) Check for recvpass/sendpass/server hostname/IP mismatches - usually the IRCd will tell you if you're running into one of these, provided you have the right server notices enabled (consult your IRCd documentation for how to do this).
|
|
2) Make sure you're not connecting with SSL on a non-SSL port, or vice versa.
|
|
|
|
If these steps haven't helped you so far, it doesn't hurt to ask for help. :)
|
|
|
|
### I turned autoconnect for PyLink on, and now I'm getting errors!
|
|
|
|
PyLink does not support inbound connections - much like regular services such as Atheme or Anope, it only connects outwards *to* IRCds. (If you don't understand what this means, it means you should turn autoconnect **off** for PyLink)
|
|
|
|
## Relay issues
|
|
|
|
### Does everyone need to install PyLink Relay for it to work?
|
|
|
|
**No!** Only the PyLink administrator needs to host a PyLink instance, as each can connect to multiple networks. Everyone else only needs to add a link block on their IRCd.
|
|
|
|
InterJanus-style links between PyLink daemons are not supported yet; see https://github.com/GLolol/PyLink/issues/99 for any progress regarding that.
|
|
|
|
### What are PyLink's advantages over Janus?
|
|
|
|
PyLink provides, in no particular order:
|
|
- More complete support for modern IRCds (UnrealIRCd 4.x, InspIRCd 2.0, charybdis 4, Nefarious IRCu, etc.).
|
|
- A flexible, maintainable codebase extensible beyond Relay.
|
|
- Cross platform functionality (*nix, Windows, and probably others too).
|
|
- Proper protocol negotiation leading to fewer SQUIT/DoS possibilities:
|
|
- Better support for channel modes such as +fjMOR, etc.
|
|
- Proper support for nick length limits with relayed users.
|
|
|
|
### My IRCd SQUITs the relay server with errors like "Bad nickname introduced"!
|
|
|
|
First, check whether the SQUIT message includes the nick that triggered the netsplit. If this nick includes any characters not allowed in regular IRC, such as the slash ("/"), or is otherwise an invalid nick (e.g. beginning with a hyphen or number), this likely indicates a bug in PyLink Relay. These problems should be reported on the issue tracker!
|
|
|
|
However, if the nick mentioned is legal on IRC, this issue is likely caused by a max nick length misconfiguration: i.e. the relay server is introducing nicks too long for the target network. This can be fixed by setting the `maxnicklen` option in the affected network's PyLink `server:` block to the same value as that network's `005` `NICKLEN` (that is, the `NICKLEN=<num>` value in `/raw version`).

|
|
|
### Clientbot doesn't relay both ways!
|
|
|
|
Load the `relay_clientbot` plugin. https://github.com/GLolol/PyLink/blob/e1fab8c/example-conf.yml#L303-L306
