Custom vhosts%0a%0a'''WARNING''': do '''not''' set individual IPv6 addresses for a user's bindhost. Do not set a user's bindhost to be something like 2605:6400:10::. If you specify an IPv6 address for the bindhost, that user can *only* connect to networks that support IPv6. IPv4-only networks completely fail.%0a%0aIt is better to set the bindhost to be username.fruit.ircnow.org. Then, for the [[openbsd/nsd|nameserver]], create an AAAA record and an A record. That way, the bindhost will use IPv6 if the network is IPv6-only, and IPv4 if it is an IPv4-only network. This solution is more flexible and allows your user to fall back to IPv4 when IPv6 is not supported.%0a%0aIf a user requests to change their vhost, do not edit the bindhost -- all you need to do is update the rDNS record (see the [[openbsd/buyvm|buyvm web panel]]. Don't delete the bindhost or the DNS A/AAAA records.%0a%0aFor example, suppose the vhost was formerly user.fruit.ircnow.org. If the user wants to change it to example.com, you just need to update the rDNS to example.com, but leave the znc bindhost as username.fruit.ircnow.org and keep the A/AAAA records for username.fruit.ircnow.org.%0a%0aOnce example.com's AAAA record is working, and the rDNS has been configured properly, you can reconnect the user (either the user types @@/znc connect@@ or you type @@/msg *controlpanel reconnect %3cusername> %3cnetwork>@@), and the vhost will update properly.%0a%0aKeeping the old A/AAAA record and bindhost working will make it easier if the user changes vhosts or if their 3rd party dns server for example.com fails for whatever reason. This method will allow the user to still connect. Otherwise, if the 3rd party dns server fails for example.com (which frequently happens with cheap, free dns services), users will be unable to connect and blame you.                                                                           %0a%0a!! Troubleshooting%0a%0aIf your user is getting disconnected, these are the most likely causes:%0a%0a# mismatch of ports or SSL (using plaintext on 6697 or SSL on 6667)%0a# SSL is not supported%0a# user has a server password where none belongs (most likely he confused server password with nickserv password)%0a# ident is not working%0a# ircd bans a certain username or ident for no good reason (the ircd mistakenly assumes your connection is a bot and glines it)%0a# typo of server name or IP address%0a# dns lookup error%0a%0aYou may be need to install icu4c-67.1 .%0a%0a!! WARNING%0a%0aIf a znc user has a bindhost that is IPv6 only but the network is IPv4 only, it will not connect.%0a%0aTo prevent this, you '''must be absolutely 100%25 certain''' that each bindhost is symbolic (such as username.fruit.ircnow.org) and that each hostname has a single A record and a single AAAA record in your DNS zone.
