Webmin in debian etch

install packages

1. access wemin/usermin official website (http://www.webmin.com/) and get the latest debian packages, or simply run:
   
   wget http://prdownloads.sourceforge.net/webadmin/webmin_1.350_all.deb
wget http://prdownloads.sourceforge.net/webadmin/usermin_1.280_all.deb
2. first install their dependent packages:
   
   apt-get install libnet-ssleay-perl libauthen-pam-perl libio-pty-perl libmd5-perl
3. therefore you can install webmin/usermin package without error message:
   
   dpkg -i webmin_1.350_all.deb usermin_1.280_all.deb
4. also update your rc*.d and so webmin/usermin will startup correctly, and able to manage by using rcconf:
   
   rm -rvf /etc/rc*d/S*webmin*
rm -rvf /etc/rc*d/K*webmin*
rm -rvf /etc/rc*d/S*usermin*
rm -rvf /etc/rc*d/K*usermin*
update-rc.d -f webmin defaults 99 01
update-rc.d -f usermin defaults 99 01
5. you can now log into your webmin interface by https://www.example.com:10000 for webmin, and https://www.example.com:20000 for usermin

some follow up and tips

1. remember to set auto-logout: the original debian's webmin package come with 15min auto-logout as default setting. this is a very good idea for increase the security level.

   go to "Webmin -> Webmin Configuration -> Authentication", active "Auto-logout after..." and set to 15min (case of webmin), or "Webmin -> Usermin Configuration -> Authentication", active "Auto-logout after..." and set to 15min (case of usermin)

2. remember to set IP access control: as like as the case of above, original debian's webmin package come with only 127.0.0.1 (localhost) restricted access to webmin as default setting.

   go to "Webmin -> Webmin Configuration -> IP Access Control", click "Only allow from listed addresses", set to 127.0.0.1 and 192.168.0.0/16 (optional, you should fill in your LAN network) (case of webmin), or "Webmin -> Usermin Configuration -> IP Access Control", click "Only allow from listed addresses", set to 127.0.0.1 and 192.168.0.0/16 (case of usermin)
