HOWTO install Webmin on Fedora

login to your shell, i will be using ssh so i send this command:

wget http://prdownloads.sourceforge.net/webadmin/webmin-1.350-1.noarch.rpm

once it has finished downloadin i send this command:

rpm -U webmin-1.350-1.noarch.rpm

The rest of the install will be done automatically to the directory /usr/libexec/webmin, the administration username set to root and the password to your current root password. You should now be able to login to Webmin at the URL http://localhost:10000/ .

Webmin install complete. You can now login to https://hostname.domain:10000/
as root with your root password.

NOTE: the default login and password is your root and root password. this is the same login you used with you ssh to your server or whatever your root password is, so your login will be like this:

Username: root
Password: xxxx (what ever your root password is)

ip_conntrack: table full, dropping packet.

It will probably look like you are experiencing a network issue with a lot of packet loss, but in fact it isn’t one at all!

This error has to do with the value in /proc/sys/net/ipv4/ip_conntrack_max set to low, and letting the system only handle a few connections at once. This value is usually imposed when APF is installed, and the following should be done to correct it:

echo “138304″ > /proc/sys/net/ipv4/ip_conntrack_max

add the following to /etc/sysctl.conf:

sys.net.ipv4.ip_conntrack_max = 138304

If you are running APF modify the following line to:

SYSCTL_CONNTRACK=”138304″

To check what the current value is you can use:

cat /proc/sys/net/ipv4/ip_conntrack_max
