Installing VSFTPD and configuring IPTables to match another server


I've been tasked with setting up a RHEL FTP server to mirror one we currently have. From what I've read, I need to install and configure VSFTPD and then configure IPTables. From what I've been able to come up with, I need to follow the steps in this article to install and setup VSFTPD. Is this a good complete article to follow you think?

http://www.cyberciti.biz/tips/rhel-f...tallation.html

Also, how do I copy the iptables config from that server to my new one? I think that iptables on our current server only allows certain IPs or blocks certain IPs (not sure which), so I need to have it do that on my new server as well.

Thanks everybody.

Without having used the tutorial (or vsftpd, for that matter)
I'd say it looks clear enough; and not many people have
complained about it on the blog. ;}

Depends on how iptables was set-up on the first machine.
You should be able to just copy /etc/sysconfig/iptables*
to the new box (maybe check the content after the copy,
and verify that any references to the original machines
IP address are changed to the new ones).


Cheers,
Tink

not many people complained, thats how i figured it was good too :-) it looked easy enough, but not sure if there were some other things it failed to mention since this will be hanging out on the internet. can't trust hackers!

Thanks for the tip on iptables.

True that. If the other machine hasn't been rooted you could
basically just clone it, modify a few bits and bobs (files that
store info about the IP and/or name of the machine) and be away
laughing ;}

If only I knew how to do that, sounds cool!

I'm not even sure how to partition my 70GB drive properly for an FTP server.

When I do a df -h I get the following, which I don't understand at all. Plus that other server has bigger drives.

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
131G 16G 109G 13% /
/dev/sda1 99M 23M 71M 25% /boot
tmpfs 506M 0 506M 0% /dev/shm

Basically that says the machine was set-up with Logical Volume Manager
and uses a /boot partition (physical), and one root partition "/" on LVM.


What's the output of
fdisk -l

From what I can tell (which isn't worth much) doesn't look like it. wouldn't it have shown in one of those two?
