[Plugin: WordPress Varnish] XMLRPC calls don't trigger purge

I have a similar issue.
To understand what the problem is I put an echo of the errno and errstr in the wp-varnish.php code..
it gives me a 13 permission denied.

I can telnet to the port on the server itself, but somehow from within wordpress it doesn’t work.

It might be the same issue you’re having

Some progress

I did 2 things
1. modifies the wp-varnish.php a little to look like this
$
if (!$varnish_sock) {
error_log(“wp-varnish error: $errstr ($errno)”);
echo $errstr;
} else {
$out = “url.purge $wpv_url \r\n”;
#$out .= “Host: $wpv_host\r\n”;
#$out .= “Connection: Close\r\n\r\n”;
$out .= “quit”;
echo $out;
fwrite($varnish_sock, $out);
fclose($varnish_sock);

echoes are not necessary but helped me find the issue.
It seems the PURGE is not accepted as all is lowercase and the call is different.
Also the Host and Connection Close are not needed.

2. This seemed to be the biggest issue on my Centos installation
run ‘setsebool -P httpd_can_network_connect 1’

Could you contact me so we can talk some more about this? Ta ??
