Trying to compile gives an error when running make:

*** No rule to make target @VMODTOOL@', needed byvcc_if.c'. Stop.

I have a centos 6.5 machine.
Installed varnish via yum and have these RPM:

varnish-libs-3.0.7-1.el6.x86_64
varnish-libs-devel-3.0.7-1.el6.x86_64
varnish-release-3.0-1.el6.noarch
varnish-3.0.7-1.el6.x86_64

Could you help please?

Hello,
Could you please give me some tips to install you great mod on my system Varnsih installation.
I've download the mod and uncompress it
I start ./configure with parameters but it doesn't work.
I'm not sure my system can use .ac files

Thank you.

Hi,

I'm planning to use this vmod for the intended purpose (bot validation) on our Varnish 4 servers, however it seems like there is no caching of results involved. Each request would trigger DNS lookups.

Are there any performance issues we should consider? Would it lock up client threads while waiting for DNS results. Maybe we should run a local DNS server on the same host or something like that to delegate caching?

Any ideas?

Thanks.

I have installed this VMOD on varnish 3.0.4/3.0.3 running on Ubuntu 12.04 as well as 10.04 and its not working. If I try changing my user agent to googlebot the connection is reset rather than forbidden.

I tried fetching using real googlebot user agent from my webmaster account and it did the same. The issue seems to be with set req.http.X-Crawler-DNS-Reverse = dns.rresolve(req.http.X-Forwarded-For);

If I remove the reverse option, I get a 403 even when its real googlebot.
I have this in my default.vcl

if (req.http.user-agent ~ "(?i)(googlebot|bingbot|msnbot|slurp|teoma)") {
# / Do a reverse lookup on the client.ip (X-Forwarded-For) and check that its in the allowed domains

set req.http.X-Crawler-DNS-Reverse = dns.rresolve(req.http.X-Forwarded-For);
# / check that the RDNS points to an allowed domain -- 403 error if it doesn't

if (req.http.X-Crawler-DNS-Reverse !~ "(?i).(googlebot.com|search.msn.com|crawl.yahoo.net|ask.com)$") {
error 403 "Forbidden";
}
/# do a forward lookup on the DNS
set req.http.X-Crawler-DNS-Forward = dns.resolve(req.http.X-Crawler-DNS-Reverse);
# / if the client.ip/X-Forwarded-For doesn't match, then the user-agent is fake

if (req.http.X-Crawler-DNS-Forward != req.http.X-Forwarded-For) {
error 403 "Forbidden";
}}```

The errors:-

Google error:- with dns.rresolve(req.http.X-Forwarded-For);

`Fetch as Google
This is how Googlebot fetched the page.

Should there be a libvmod_dns.a? Both throttle and shield are working and were compiled the same way

Why?
I'll update Varnish, but I don't want to do that now. 😕

Hi
is there any way to support Varnish 4.1?

my varnish is 4.1x , aclocal: couldn't open directory `m4 error when I run the autogen.sh
