java port 80 and root privilege

Mon, 8 Mar 2010 11:13:06 +0000

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

freebsd firewall

Sat, 27 Feb 2010 15:14:25 +0000

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

always thought I was not normal, until this....
