realhost

Description

The solanum.chat/realhost capability causes the server to add messages tags to messages sent by a user showing that user's IP address and hostname, when visible.

The tag indicating IP address MUST be named solanum.chat/ip and specifies the IP address of the sender.

The tag indicating hostname address MUST be named solanum.chat/realhost and specifies the hostname of the sender.

Servers supporting this capability MAY be configured to restrict visibility of these tags.

When allowed, the tag is added to all commands sent by a user (e.g. PRIVMSG, MODE, NOTICE, and all others) and numeric replies sent on behalf of the user.

@solanum.chat/ip=2001:db8::1 :glguy!x@2001:db8::1 PRIVMSG friend :My IP doesn't resolve to a hostname.
@solanum.chat/ip=2001:db8::1 :glguy!x@example.com PRIVMSG friend :Mine does.
:glguy!x@user/glguy PRIVMSG friend :Unprivileged user doesn't see though spoof.

@solanum.chat/ip=2001:db8::1;solanum.chat/realhost=example.com :glguy!x@user/glguy PRIVMSG staffmember :Privileged users might see through spoofs.

Solanum Implementation

The solanum.chat/realhost tag requires the receiver to have the auspex:hostname privilege.

The solanum.chat/ip tag is not sent for senders with a configuration file IP spoof.

The solanum.chat/ip tag requires the receiver to have the auspex:hostname privilege when a sender has a dynamic IP spoof.
