If I remember correctly, webmin was removed from Debian due to security issues. Anyway, webmin provides an Debian package:
prdownloads.sourceforge.net/weba … 30_all.deb
You have to install some dependencies, such as libauthen-pam-perl apt-show-versions. Theses packages are only in the unmaintained repository.
An example[code]
download package
wget http://prdownloads.sourceforge.net/webadmin/webmin_1.730_all.deb
activate unmaintained repository and install dependencies
ucr set repository/online/unmaintained=‘yes’
univention-install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python
install webmin
dpkg -i webmin_1.730_all.deb
open port 10000
ucr set security/packetfilter/package/webmin/tcp/10000/all=ACCEPT
/etc/init.d/univention-firewall restart
[/code]
Unfortunately, if ssl is activated, webmin segfaults. SSL can be disabled in /etc/webmin/miniserv.conf but I think it is not the best idea. Maybe someone knows webmin and perl better and can have a look.
