Identification of source rpm of an installed binary is essential at some points especially during upgrades or conflicting libraries.
Let us check which rpm provides /usr/sbin/sshd
RedHat
The source RPM can be identified using the following options
# rpm -q --whatprovides /usr/sbin/sshd openssh-server-5.3p1-94.el6.x86_64
Another Handy tool is
root@server [/]# rpm -qf /usr/sbin/sshd openssh-server-5.3p1-94.el6.x86_64
Dabian
In Debian based systems there are two ways one is using apt-file & dpkg -S
apt-file installation
This binary may not be available in all installation. Below are the steps to be used for the installation
apt-get install apt-file
Once this is done update the db using the following commands
apt-file update
The above check will give the result as given below
# apt-file search /usr/sbin/sshd openssh-server: /usr/sbin/sshd
Using dpkg -S
# dpkg -S /usr/sbin/sshd openssh-server: /usr/sbin/sshd
