I'm trying to set up a proxy server on an Ubuntu Box, but my linux-fu is pretty weak and I'm stymied with an iptables issue.
I'm trying to execute this command:
iptables -A INPUT -d xxx.xxx.xxx.xxx -p tcp -m –dport 443 -j ACCEPT
The error I get back is this:
iptables v1.4.4: Couldn't load match `-dport':/lib/xtables/libipt_-dport.so: cannot open shared object file: No such file or directory Try `iptables -h' or 'iptables --help' for more information.
There is, in fact, no file with that name.
iptables was not installed on my machine, I did:
apt-get install iptables
to install it. Finally, here's my distro info:
DISTRIB_ID=Ubuntu DISTRIB_RELEASE=10.04 DISTRIB_CODENAME=lucid DISTRIB_DESCRIPTION="Ubuntu 10.04 LTS"
Any idea what's going on? If this is an obvious question, please point me to the relevant documentation; I'm kinda lost on even where to look, and Googling pulls up nothing.
