Ubuntu Natty: activate old scrollbars in Ubuntu Classic

2011-05-04 by xpheas

Natty comes with new overlay scrollbars. The work fine in the filebrowser but not in Eclipse (the overlay does not appear). So i deactivated the new scrollbars to get the old one back.

BASH-Code:

1

sudo su
echo "export LIBOVERLAY_SCROLLBAR=0" > /etc/X11/Xsession.d/80-disableoverlayscrollbars

Port forwarding with iptables

2011-02-27 by xpheas

I am using a Linux gateway with an public IP-address to access the Internet.
To access an internal machine on port 80 beind the gateway from outside I created the following forwarding rule (iptables).

BASH-Code:

1
2

iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j DNAT --to 192.168.100.50:80
iptables -A INPUT -p tcp -m state --state NEW --dport 80 -i eth0 -j ACCEPT

The first rule does the forwaring job, the second allows new incomming connections on port 80.

Now the webserver on Port 80 behind the gateway is accessible over the public IP.

If you are in a foreign network and want to secure up your HTTP traffic you can use an SSH Tunnel:

BASH-Code:

`1`	ssh user@host -NfD 8080

Configure Firefox:

SOCKS-Host: localhost
Port: 8080

To tunnel DNS lookups open about:config and change network.proxy.socks_remote_dns to true
