Install whois On CentOS Linux Using Yum Package Manager
Posted by alex in Insights at 3:38 PMEarlier today I needed to lookup the origin of some IP’s and I typically use whois but it wasn’t installed on the CentOS server I was working on. Attempting to install whois failed so below there is information on installing whois using the yum package manager on CentOS.
whois Not Installed On CentOS Linux:
[root@dev ~]# whois -bash: whois: command not found
Above you can see that the whois command is not currently installed on this CentOS Linux server. Below we describe how to use yum to search for what package installs whois and then we install the correct package.
Use yum whatprovides To See What Installs A Specific Application On CentOS:
[root@dev ~]# yum whatprovides *bin/whois* Loading "installonlyn" plugin Setting up repositories Reading repository metadata in from local files jwhois.x86_64 3.2.3-8.el5 base Matched from: /usr/bin/whois [root@dev ~]#
As you can see above the jwhois package installs the whois application. The yum whatprovides command can be very useful for figuring out what package installs a specific application.
Install jwhois Package Via Yum On CentOS Linux:
[root@dev ~]# yum install jwhois Loading "installonlyn" plugin Setting up Install Process Setting up repositories pgdg83 100% |=========================| 1.9 kB 00:00 rpmforge 100% |=========================| 1.1 kB 00:00 base 100% |=========================| 2.1 kB 00:00 updates 100% |=========================| 1.9 kB 00:00 addons 100% |=========================| 951 B 00:00 ruby 100% |=========================| 951 B 00:00 extras 2.1 kB 00:00 Reading repository metadata in from local files Parsing package install arguments Resolving Dependencies --> Populating transaction set with selected packages.

[root@dev ~]#
Now that jwhois has been installed you should be able to use whois from the CentOS command line as shown in the below example.
Use whois On CentOS Linux:
[root@dev etc]# whois 136.165.238.241 [Querying whois.arin.net] [whois.arin.net] # # Query terms are ambiguous.
