For security reasons it is not possible to run a java program on linux on ports lower then 1024.

It will throw an exception like :
java.net.BindException: Permission denied:80

For this you can either choose to run the progam as root or route the requests via iptables :

iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080

setting up a firewall that blocks all ports and only allow ports needed. do not lock yourself (ssh) out!

modify /etc/rc.d to contain following lines:
pf_enable="YES"
pf_rules="/etc/pf.conf"

create file /etc/pf.conf and modify following lines (use ifconfig to detect settings) :

ext_if="re0" # replace with actual external interface name i.e., dc0
int_if="lo0" # replace with actual internal interface name i.e., dc1
internal_net="127.0.0.1"
external_addr="138.125.203.14O"

tcp_public_services="{ 21, 22, 25, 53, 80 }"
udp_public_services="{ 21, 22, 25, 53, 80 }"
tcp_priv_services="{ 20, 21, 110, 8009 }"
udp_priv_services="{ 20, 21, 110, 8009 }"

kldload pf

test the rules
pfctl -n -f /etc/pf.conf

apply the rules
pfctl -f /etc/pf.conf

start: /etc/rc.d/pf start

To create a regular expression that does not match a URL ( or more ) but matches another, or more, the following can be used. First two negate the match with ?! .


(?!/ui/login.do)(?!/ui/registration/.*)(/ui/.*)

To record your desktop on linux, you can use xvidcap.
At first there were some problems with the audio but these dissapeared after installing a new version.

It's a nice screen capturer with possibility of saving in flv, avi and more with support of all the video codecs libavformat can handle.

basically to cut and split video on linux you need to install mplayer and mencoder.

mencoder input.flv -ovc copy -oac copy -of lavf -o result.flv -ss 00:00:01.01 -endpos 00:04:04

-ovc refers the video codec ( copy, libx264, mpeg4 )
-oac refers the audio codec.
-ss starting time
-endpos ending time

mencoder can practically handle all formats like avi, mp4, flv.

check the man for more info.
mencoder can easy be installed by standard distributions.

sudo apt-get install mencoder

also ffmpeg can be used for cutting and splitting.
