how many ws can you find in:
q: ssl connection refused im getting connection refused errors for some sites being served over ssl on my ubuntu box (10.04 lts). it doesnt affect all sites: https://github.com/, for example, loads no problem, but https://codeeval.com does not.
ive checked my firewall settings, and there are no rules affecting connection to sites over port 443. but running nmap yields the following:
$ nmap -st -r -n -p443 codeeval.com

starting nmap 5.00 ( http://nmap.org ) at 2011-06-22 11:25 bst
interesting ports on 184.72.48.116:
port    state  service
443/tcp closed https

nmap done: 1 ip address (1 host up) scanned in 1.31 seconds

to check that it wasnt a problem with the site, i sshd into another computer on my local network and ran the same command, this time getting:
$ nmap -st -r -n -p443 codeeval.com

starting nmap 5.00 ( http://nmap.org ) at 2011-06-22 11:37 bst
interesting ports on 184.72.48.116:
port    state service
443/tcp open  https

nmap done: 1 ip address (1 host up) scanned in 0.53 seconds

theres clearly something wrong with my local config, but i cant work out what might be causing it. i havent been able to track down any meaningful log messages; the only response when i try to connect is connection refused.
does anyone have any insight into what might be causing this?

a: actually, ive found the solution. i followed the advice here - ssh connection refused - which i assumed to be an unrelated problem.
clearing the ip tables and resetting the rules fixed my problem.
edit - a follow up:
ive also determined what caused the problem, though im now looking for a long-term solution. it would seem that the changes made to my ip tables made by software called ipblock persist even after the application process has ended. the only way i can seem to prevent this is by flushing the tables after i quit ipblock. does anyone have any better suggestions?
