Hello all,

I'm dealing with a challenging problem on my server that's causing a lot of symptoms. I've narrowed down what I think is the root problem. Here's where I'm at:

1) My Curl is not able to access Port 80. Other ports work no problem. So I can CURL any https URL, but not http URLS.
2) The problem isn't CURL, as when I use SVN, I can use repos that are https, but not http.
3) IP Tables seems to be OK as far as configuration goes, but there does appear to be a problem when I restart it. Here's what happens when I run iptables -;
https://pastebin.linode.com/8064

4) Here's what happens when I issue service iptables restart



As you can imagine, this is all quite frustrating since PHP wraps CURL and pretty much everything is broken. Yum is even broken.

Thank you,


Josh

What does iptables -S say? I'm leaning toward your output rules.

Pastebin the output of the following when curl is having this problem:

iptables-save

For #4, that is a problem with CentOS not understanding what the security table is. There's a patch for it, but the site hosting it is currently down, and I can't find another copy anywhere.

out of curiosity what are the contents of /etc/sysconfig/iptables?

Thanks Linode Support and everyone who responded.
