I tried:

root@host [/home]# yum install iftop
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
 * base: centos.mirrors.tds.net
 * extras: yum.singlehop.com
 * updates: mirror.wiredtree.com
Setting up Install Process
No package iftop available.
Error: Nothing to do

So how to do it?

What should I do to be able to do so?


You can either download the source code and compile the package yourself, or you can downloaded the binary package for your distribution.

Have a look at http://pkgs.repoforge.org/iftop/ as it provides binary packages for RHEL/CentOS and the source.

To install the binary package on CentOS-6 64-bit just do the following:

wget http://pkgs.repoforge.org/iftop/iftop-0.17-1.el6.rf.x86_64.rpm
rpm -ivh iftop-0.17-1.el6.rf.x86_64.rpm

iftop available in EPEL repository:

# rpm -ivh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
  • I did that. Now how to run iftop? I run it and nothing shows up – user4951 Jul 11 '14 at 4:36
  • after adding repository run this: yum install iftop – manuel Mar 13 '15 at 14:23

For CentOS 7 (fully updated today), install from EPEL repository

yum install epel-release -y
yum install iftop -y

Not 100% sure, but I think earlier versions require downloading the EPEL repository and installing manually using rpm, then you can just "yum install iftop" (as per other answers)

  • Yes it works for me! – newguy Aug 24 '17 at 16:19

For Centos 7 you can do this:

rpm -i http://mirror.pnl.gov/epel/7/x86_64/i/iftop-1.0-0.7.pre4.el7.x86_64.rpm

    sudo yum install libpcap && rpm -i https://dl.fedoraproject.org/pub/epel/7/x86_64/i/iftop-1.0-0.12.pre4.el7.x86_64.rpm worked for me - also you posted a mirror – Jose Alban Feb 8 '17 at 11:25
