Hi
I am new to CentOS and been into Linux for about 3 months now. I first
started off with fedora and also trying my hands on CentOS now.
Basically i used yum to download softwares on the fedora box. I mainly
require the snmp agent for my linux boxes so as to test my network
management product
Thanks John.
Actually had to use "yum clean all" and then used yum to install the
net-snmp package and it worked great.
Good to go with my testing.
Appreciate your help in this regard.
Thanks

I wanted to download and install the net-snmp package. Usually on my
other CentOS boxes i use the following command to do it:
yum install net-snmp
I was able to successfully install net-snmp on 4 of my CentOS boxes but
not on one of them. It reports me the following error message:
