I noticed that I wasn’t able to connect to RHN and was able to troubleshoot the problem down to a DNS problem. However, I’m able to ping the DNS IP’s. I’m not able to dig them though.
I thought the problem might be with iptables, so I tried to flush it by:
I get this error:
/lib/modules/2.4.18-24.8.0/kernel/net/ipv4/netfilter/ip_tables.o: init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg

iptables v1.2.6a: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
I also tried booting with a earlier kernel version, but I get the same error.
