Need to open port 10000 for webmin and 21 for FTP in Centos?
Solution 1
Based on the iptables output you posted, everything is already open. In fact, your not blocking anything!
Solution 2
when you want to change it manually, here is a good tutorial:

Otherwise you could use the programs system-config-securitylevel
or system-config-firewall
.
Solution 3
iptables -I INPUT -p tcp --dport 10000 -s 192.168.1.0/24 -j ACCEPT
iptables -I INPUT -p tcp --dport 21 -s 192.168.1.0/24 -j ACCEPT
And save the changes to iptables :
iptables-save > /etc/sysconfig/iptables
Solution 4
You might want to reconsider opening those ports since Webmin is notoriously full of bugs and ftp sends usernames and passwords in plain text. Better to ssh in and tunnel through that to gain access to Webmin (or just learn to manage the server without Webmin, which in the long-term is a far better option). For ftp, consider replacing it with sftp/scp.

How can I open these two ports in CentOS? I have used Ubuntu before, but I never had to manually open any port.
When I enter iptables -L, I get output like this:
Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination [root@sachinvasudev test]#
