OpenClipart.org has a large collection of nice clip art, and it’s all free and in the public domain. It’s the backend for the clip art libraries of, among other things, OpenOffice.org.
In following these instructions to get Xen setup with a NAT configuration for guests, I encountered the classic error:
# iptables -L
FATAL: Module ip_tables not found.
iptables v1.3.6: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
I can never remember what kernel options are necessary for NAT. They’re described in a post to xen-users here:
Networking —> Networking options —> Network packet filtering
(replaces ipchains) —> Core Netfilter Configuration —> Netfilter
Xtables support (required for ip_tables) and do enable all modules
included in that as per your need.
Then go to – Networking —> Networking options —> Network packet
filtering (replaces ipchains) —> IP: Netfilter Configuration —>
IP tables support (required for filtering/masq/NAT)
You can only go to the second step after doing the first one.
The Perfect Xen Setup for Debian and Ubuntu has a nice explanation of how to setup iptables and port forwarding.
echo "1" > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -s 192.168.0.0/16 -j MASQUERADE
### Port Forwarding ###
iptables -A PREROUTING -t nat -p tcp -i eth0 --dport 80 -j DNAT --to 192.168.3.2:80
iptables -A PREROUTING -t nat -p tcp -i eth0 --dport 25 -j DNAT --to 192.168.3.3:25
iptables -A PREROUTING -t nat -p tcp -i eth0 --dport 110 -j DNAT --to 192.168.3.3:110
You must also `chmod 755 /etc/network/if-up.d/iptables`.
Here is a page which claims Minimal Xen + Etch. So far, it’s my favorite.
I’m successfully using js2-mode. Don’t forget to byte-compile it first.
