Common operations on IPv4-to-IPv6-Proxy

This document only concerns operations by ungleich staff. See How to use the IPv4-to-IPv6-Proxy page for user documentation.

Status

This document is IN PRODUCTION.

HTTP / HTTPS proxying.

  • It's configured by cdist, type __ungleich_haproxy
  • To add a domain, edit manifest/ungleich
    • Find either ipv6-proxy.place5.ungleich.ch OR ipv6-proxy.place6.ungleich.ch
    • Verify that the domain has an AAAA entry
    • Add the domain using the "--v4proxy DOMAIN" parameter
    • Commit in git, push
  • Run cdist: (either of them)
    • cdist config ipv6-proxy.place5.ungleich.ch
    • cdist config ipv6-proxy.place6.ungleich.ch

Troubleshooting

If the customer domain does not exist (anymore), haproxy will refuse to reload. In this case the customer domain has to be removed and the customer to be notified.

SMTP proxying (experimental)

  • Configured by cdist, type __ungleich_smtp_proxy.
  • To add an entry, edit manifest/ungleich.
    • Find configuration entry for ipv6-mx.ungleich.ch.
    • Add --proxy domain.tld entry to the __ungleich_smtp_proxy type. Make sure that ipv6-mx.ungleich.ch is not the primary MX of domain.tld:t we will have routing loops if it is the case.
    • Commit, push.
  • Deploy with cdist config -v ipv6-mx.ungleich.ch.

Troubleshooting

Postfix's logs can be found in /var/log/messages on ipv6-mx.ungleich.ch.
