Linux error on Iptables


I have a web server running on my linux 2.4.18. The problem I'm having is from the web server I can't ping out the the world or trace route. I have checked my firewall setting and all my ip setting and they are correct. From my local PC I can ping the ip address of the server. When I do a iptables -L, I get this message:

/lib/modules/2.4.18-3/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
/lib/modules/2.4.18-3/kernel/net/ipv4/netfilter/ip_tables.o: insmod /lib/modules/2.4.18-3/kernel/net/ipv4/netfilter/ip_tables.o failed
/lib/modules/2.4.18-3/kernel/net/ipv4/netfilter/ip_tables.o: insmod ip_tables failed
iptables v1.2.5: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Does anyone have any ideas on this. I more of a networking guy so this is still really new to me.

thanks in advance

http://www.iptables.org/
The Netfilter HomePage: iptables 1.2.5
This version requires kernel >= 2.4.4 This version recommends kernel > 2.4.14

I suggest upgrading, you're lagging a few versions
behind.


Cheers,
Tink

Since your firewall/NAT scripts are likely to be using
iptables I'd think so ;)

Just download and install a newer iptables to match
your kernel modules.
No need for a system upgrade.

Whoa, I apologise... god I have to read before I write...

Sorry it appears you were told to upgrade IPTABLES, not your KERNEL. This is right.

Just cuz I am cold here in Canada right now, I'll let you guys flame me. Here's my orig. post:

?!?!?!? What on earth are you people on about??? version 2.4.18 IS later than 2.4.4... eighteen is certainly larger than four, last I checked my calculator. My 2.4.18 RH8 box runs iptables with no issue at all. 2.4.18 is a new enough kernel to do most iptables functions. but you may have to compile netfilter into your kernel if it doesn't have it already compiled in (most, if not all distros will have this).

You do NOT need a newer kernel if you are using 2.4.18, though you might need to recompile the existing one.

HTH
