iptables installation problem

[ads nat]

[-- Attachment #1: Type: text/plain, Size: 895 bytes --]

Hi,
I am trying to install iptables-1.2.8.tar.bz2 on Linux 8.0 server.
I have downloaded iptables-1.2.8.tar.bz2 file from netfilter downloads to /root/iptables-1.2.8 directory. 
by using command 
"tar -xf iptables-1.2.8.tar"
It has created iptables-1.2.8 directory in which all files are extracted.
 
I don't know how to go further.
I tried make and make install.
 
Then when i gave command "/etc/rc.d/rc.local"
it gives following error.
"[root@xyz iptables-1.2.8]# /etc/rc.d/rc.local
SIOCDELRT: No such process
RTNETLINK answers: File exists
SIOCADDRT: File exists
SIOCADDRT: File exists
iptables v1.2.6a: can't initialize iptables table `-nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
 
How to go ahead now?
 
Thanks

After this you have to compile the iptables.

Hi,

To save yourself a bit of trouble, you may download the Red Hat rpm for 

iptables-1.2.8-8.80.2.i386.rpm

either using up2date, or checking their ftp site.

This should be

Make sure that you have removed (-) from -nat above. This is a syntax
error.

Hi,
I have Linux server REDHAT 8.0 installed with iptables v1.2.6a. I have upgrade it to 
v 1.2.8 by installing 1.2.8. But when I check iptables -V. It shows 1.2.6a version. Do i have to delete iptable file before installing 1.2.8?
Thanks.

No, read the INSTALL and README files, especially the bit about LIBDIR,
etc.

Did you install a Redhat iptables update by rpm or did you download and 
build your own? Normally a Redhat rpm automatically restarts a service 
after it updates it, but if it didn't

/etc/rc.d/init.d/iptables restart

will do the job. If you installed someone else's rpm or built your own 
binary from source, make sure that your startup script path points to 
the new version. I'm not aware of any reason you should have to delete 
the old version, although it's generally good practice to remove any 
unused software from a firewall box.

I have downloaded from netfilter.org and built. If rpm upgrade is easy please guide me and i will do it.

Redhat makes update RPMs available for all the packages in their 
distros. You can configure and run "Update Agent" or you can go to their 
site at http://www.redhat.com/apps/download/ to find them. You can also 
find the update file tree at a mirror site. This is the one I use:

ftp://mirrors.kernel.org/redhat/redhat/linux/updates/8.0/en/os/i386.

Download the file then run:

rpm -Uvh /yourfilepath/yourfilename

This will update iptables, but it won't change your config files. If the 
current version isn't running correctly then updating probably won't 
solve your problem. Hope this helps,  Jeff
