External Link Checking

We are currently on Cascade Server 6.4 (and started after the 6.0 release). One of the things in my "todo pile" is getting the external link checking working. I'm at a loss. Cascade is on a linux server (RHEL) , and I can use links or lynx to browse to a website from the server, but if that site's URL is used in a page, the external link check just times out.

Has anyone gotten the external link checker working? If it "just works" please let me know. But, if there's a trick I'd love to hear that too.

It feels like a "firewall" kind of thing, but like I said, I can browse from the server. Did I miss doing something in my tomcat setup to give it permission?

Thanks all,

    The link checker uses HTTP Head requests to verify the validity of external links. From a Linux machine terminal with the cURL utility installed, try:

    curl -i -I <url>

    and make sure you get 200 OK response code.

    Are you definitely getting a link check timeout? If so, also try upping the "External Link Check Timeout" System Preference

    /me smacks head.

    It was the timeout. 1s just wasn't enough for a lot of the pages they are linking to.

    Upped to 10s and works fine.

    I just felt my inner-sense of awesomeness drop by 1.
