libnss_log

A NSS-Library which logs all hosts requests to /tmp/nss-log-UID.log.

Usage

1. Install libnss_log
2. Add log to the hosts line in /etc/nsswitch.conf.

(Usually) the line should look like this:

hosts: files log ...

Example log output:

gethostbyname wpad
gethostbyname wpad
gethostbyname github.com
gethostbyname github.com
gethostbyname github.githubassets.com
gethostbyname github.githubassets.com
