LJupdate plugin error

techiem2 · Post by **techiem2** » Thu Nov 15, 2007 6:58 pm

I'm trying to use the LJupdate plugin to mirror posts between 2 copies of my S9y blog, but it's not working.
When I save a post, I get the following error:

Posting to Serendipity...
XML_RPC_Client: Connection to RPC server :80 failed.
Notice: XML_RPC_Client: Connection to RPC server :80 failed. in /var/www/localhost/htdocs/bundled-libs/PEAR.php on line 848
XML_RPC_Client: Connection to RPC server :80 failed.

any suggestions?

Thanks.

Hi!

This sounds like you didn'T configure the LJ server in the plugin?

It's configured.
I just put the domain name in, as shown in the example.
Didn't put it in as http://domain.
I didn't fill in the LJ Cut text or Category ID fields, but I figured those were optional.

Thanks

When I put in the domain as http://domain, it doesn't throw the error on post, but it's not showing up in the other blog...

Hi!

Is your server maybe firewalled? Can you send outgoing trackbacks or install plugisn through spartacus?

Spartacus works fine on both servers.
I have the XML-RPC plugin installed on the remote server so it should be able to accept posts.

Hi!

What URL did you enter for the remote server? The error message indicates that it cannot connect to that host...

Ok.
Here's the pretty much full details.

I'm trying to post from my home blog at
https://techiem2.no-ip.com
to the domain blog at
http://www.techiem2.net
Both running s9y.
Both are installed to the root of the webspace.

I have the XML-RPC plugin installed on the remote blog.
Spartacus works fine on both blogs.

When I enter the LJ Server field as www.techiem2.net, techiem2.net, www.techiem2.net/, etc. it gets the error.

If I enter it as http://www.techiem2.net or http://www.techiem2.net/, it doesn't show any errors, but the post doesn't show up on the remote blog.

Hi!

When using http:// the plugin code doesn'T recognize this, I think. So "www.techiem2.net" would be the proper thing to use.

Please put this code on the blog directory as "xmltest.php" from where you're posting from:

Code: Select all

<?php
$fp = fsockopen('www.techiem2.net', 80);
fputs("GET /serendipity_xmlrpc.php HTTP/1.0\r\nHost:www.techiem2.net\r\n\r\n");
while(!feof($fp)) {
  echo htmlspecialchars(fread($fp, 4096));
}
fclose($proxy_fp);

Then call that PHP script via https://Techiem2.no-ip.com/xmltest.php

Garvin

It sits and spins for a while then eventually gives:

Code: Select all

Warning: Wrong parameter count for fputs() in /var/www/localhost/htdocs/xmltest.php on line 3

Warning: fclose(): supplied argument is not a valid stream resource in /var/www/localhost/htdocs/xmltest.php on line 7

If I wget the file, I get a file with this content:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

Hi!

That means your server indeed is firewalled and cannot connect to the remote host. Please ask your server admin about firewalling and connection issues, this is definitely not a PHP/s9y issue...

I am the server admin for the local site.

The server is allowed direct access to the net.
The wget test was done from that box.
I also checked with links from that box and can browse the remote site fine with it.

Maybe I have a php option or something that's keeping it from retrieving remotely?

Guess I'll start digging around my configs and such.
Probably something really simple....
hehe

Hi!

Is your PHP running as CGI or as mod_php? Do you have things like mod_security or suhosin running? Do you have changed your default php.ini? (allow url/socket connects?)

Regards,
Garvin

techiem2 · Post by **techiem2** » Wed Apr 30, 2008 11:17 pm

Ok, I finally got back to looking into this a bit.
PHP is running mod_php.
I don't think I have mod_security or any such thing running.
I tried testing again using the sample code at http://us2.php.net/fsockopen
and got the following when I hit the test page on my site:

Code: Select all

Line 1 appears to be a blank line. This is invalid XML.

In the past we've seen this kind of error when one of the files involved has a blank before the <?php tag.

Unfortunately, if this is the problem, you'll need to check each file to find the extra blank. (If you've got some programming skill, you can follow the code and only check the files in the execution path. Or program something that removes any blank lines at the beginning of the file.)

I recently checked in some code that validates an upload with checksums, but it hasn't been extensively tested. In fact, so far as I know, I'm the only person who has tested it, although I've done it on two sandbox instances. If you're feeling daring, or you have a sandbox to test on, you can get the latest nightly and give it a spin.
