Sometimes (e.g. when using an external API), a script wants to connect
by name to a server and doesn't care whether IPv4 or IPv6 is used. By
passing the "any_af" option, the first resolved address of any address
family will be used, allowing external-category scripts which used to
fail with -6 to succeed.
http-xssed unconditionally used host.targetname, which is only set when
the target is specified as a name, not an IP address or range. Now we
prefer the targetname, but fall back to the reverse-dns name, and
finally to the IP address. Perhaps we should be more strict, if
xssed.com only allows domain names, for instance?
for lib in nselib/*.lua*; do l=${lib#*/}; l=${l%.lua*}; find . -name \
\*.lua -o -name \*.nse | xargs grep -l "require .$l\>" | xargs grep \
-c "\<$l\." | grep ':0$' | awk -F: '{print "'$l'", $1}'; done
Did not remove calls to stdnse.silent_require since these can be used to
abort script execution if OpenSSL is not included, even if the script
does not directly call openssl.* (perhaps it uses comm.tryssl instead,
for instance).
Also did not remove require "strict", since that library is special and
modifies the environment.
Mostly found with:
for i in nselib/*.lua scripts/*.nse; do
echo $(perl -lne 'BEGIN{$a=$p=0}next unless $_;/^(\s*)/;' \
-e '$l=length$1;next if$l==$p;$a+=(abs($l-$p)-$a)/$.;' \
-e '$p=$l;END{print$a}' $i) $i
done | sort -nr
And indented with: https://gist.github.com/bonsaiviking/8845871
whois-ip.nse was particularly mangled (probably my fault due to using
vim's built-in indentation script, but it could be structured better)
Clean up some typos and differences. Most have been normalized to
whatever form of the name occurred in the largest number of scripts.
