Comments on Extending Perfect Server - Debian Squeeze [ISPConfig 3]

Extending Perfect Server - Debian Squeeze [ISPConfig 3] The following tutorial will extend the "Perfect Server.... " for ISPConfig 3 with BIND & Courier installed in Debian Squeeze. It explains how to change default ports (ssh, ispconfig, webmin), how to install some useful applications (webmin, roundcube, atop, htop, multitail, tiger etc), how to update awstats periodically (more than once a day) or whenever you want, how to create clients' data backups (periodically) accessible under their folder and finally it explains how to tweak your system for performance (mysqltuner, tuning-primer) or security (custom firewall rules, (D)Dos Deflate, fail2ban modified).

There is a small typo in download of the webmin

cd /tmp wget http://prdownloads.sourceforge.net/webadmin/webmin_1.530_all.deb

should actually be

cd /tmp

wget http://prdownloads.sourceforge.net/webadmin/webmin_1.530_all.deb

Hi, I've followed the perfect debian server with ispconfig3 tutorial, then the SSL post on faqforge, and everything went ok on my virtualized server and on the online one. Once it gets to changing default port for webmin, activating it on ispconfig firewall, restarting webmin and apache, and no way, the page I get on the browser (url is https://x.x.x.x:1888) is (Chrome in this case, but the timeout is consistent for all browsers.

Error 118 (net::ERR_CONNECTION_TIMED_OUT)

I've checked with a netstat, but the port is listening

tcp 0 0 0.0.0.0:18888 0.0.0.0:* LISTEN 32521/perl

udp 0 0 0.0.0.0:18888 0.0.0.0:* 32521/perl

an iptables list gives this response

So, everything seems in order, what could it be stopping me from accessing webmin from alternative port? Please consider that default port works, and all other services work, since I've followed letter by letter you instructions...

Did I forget anything? Where could I look?
