Hello.
I'm working with RedHat 7.1. It's connected to Internet (eth1) and to my LAN (eth0).
I would like to allow my LAN users access IRC, ping, FTP, ... through my RedHat box.
I heard about iptables, ip-masquerade or ipchains in order to perform this. So I checked this RedHat to know if they were installed.
ipchains -L :
Chain input (policy ACCEPT):
target prot opt source destination ports
ACCEPT all ---f-- anywhere anywhere n/a
acctin all ------ anywhere anywhere n/a
......
iptables:
ip_tables.o: init_module: Device or resource busy
ip_tables.o: insmod /lib/modules/2.4.2-2smp/kernel/net/ipv4/netfilter/ip_tables.o failed
ip_tables.o: insmod ip_tables failed
iptables v1.2.1a: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
ipfwadm:
ipchains failed!
If this command worked with the original ipfwadm 2.3, please
submit a bug report to `ipchains@rustcorp.com'. Note that you
now need to be root, even to list the chains (complain to Alan Cox).
...
I would be extremely obliged if anybody could explain the sense of these messages. I suppose that 'ipchains' is running, isn`t? But why iptables and ip-masquerade are installed and giving errors?
Shall I use 'ipchains' to allow my LAN users access several protocols?
Thank you very much in advance. Wishes.
