The issue names -pa, the fastdialer.IP context value, favicon requests, ztls handshakes, and -maxhr, but does not identify source files or tests. Start by tracing how -pa passes IPs into the dialer and how redirects and auxiliary requests use that context; the issue says the implementation is in #2668 and depends on projectdiscovery/fastdialer#580. Done means a given IP is used while hostname-based Host and SNI are preserved, with the listed redirect, IPv6, favicon, ztls, and per-IP error cases handled.

Descripción

Type: Enhancement
Please describe your feature request:

An input line that gives the ip to probe a target through, like curl --resolve: the connection goes to the ip, and the hostname stays in the Host header and SNI. The JSON line nuclei would use for the same thing (https://github.com/orgs/projectdiscovery/discussions/7862) fits, so one list could feed both tools:

{"target": "https://app.example.com", "ip": "192.0.2.10"}
{"target": "https://app.example.com", "ip": "192.0.2.11"}
Describe the use case of this feature:

Probing a vhost on a given server, an origin behind a CDN, or one host on each of its servers. The vhost,ip input form builds the URL from the ip and sends the vhost only as the Host header, so there is no SNI, and url and host report the ip. -pa probes the ips DNS returns, not given ones, and the way it passes each ip doesn't reach them correctly. With app.test resolving to 127.0.0.1 and 127.0.0.2, a server on each whose title is its address, and redir.test redirecting to other.test, which resolves to 127.0.0.3 (dev at c9148f0):

$ echo http://app.test:18080 | httpx -pa -title -ip -silent
http://app.test:18080 [srv=127.0.0.2 host=app.test:18080] [127.0.0.1]
http://app.test:18080 [srv=127.0.0.2 host=app.test:18080] [127.0.0.2]

$ echo http://redir.test:18201 | httpx -pa -fr -title -ip -sc -silent
http://redir.test:18201 [302,200] [srv=127.0.0.1 host=other.test:18202] [127.0.0.1]
  • -pa passes each ip in the fastdialer.IP context value, and fastdialer serves the second ip from the dialer cached for the first one (projectdiscovery/fastdialer#579, PR projectdiscovery/fastdialer#580).
  • That value pins every dial made for the request, so a redirect to another host followed with -fr goes to the probed ip.
  • IPv6 ips are passed in brackets, which fastdialer doesn't accept as an ip, so those probes fail with no ips provided in dialWrap.
  • The favicon request and the ztls handshake are made with context.Background(), so they drop the ip and reach the host through DNS, and -maxhr counts errors per host:port, so errors on one ip skip the other ips of the host.

Implemented in #2691, which replaces #2668. The fastdialer change it needs (projectdiscovery/fastdialer#580) is released in v0.6.0, which dev already requires.
