Hi, I am quite new to UNIX. I have been following a tutorial to turning my Raspberry Pi into a wireless router. Part of the process was to install isc-dhcp-server. I think this install created a directory /etc/dhcp/ where it stores the config files for the server.
However I just noticed while traversing around the directories that there is also a directory /etc/dhcp3/ and also a couple of files /etc/dhcpcd.conf and /etc/dhcpcd.duid. This looked to me like another version of DHCP was already installed. So I did a `dpkg -l | grep dhcp` and I got the following results:
ii dhcpcd5 6.7.1-1+rpi5 armhf DHCPv4, IPv6RA and DHCPv6 client with IPv4LL support
ii isc-dhcp-client 4.3.1-6+deb8u2 armhf DHCP client for automatically obtaining an IP address
ii isc-dhcp-common 4.3.1-6+deb8u2 armhf common files used by all of the isc-dhcp packages
ii isc-dhcp-server 4.3.1-6+deb8u2 armhf ISC DHCP server for automatic IP address assignment
So I feel like I have installed (or at least parts of) 4 different version of DHCP:
* dhcp3
* dhcpcd
* dhcpcd5 (this could be the same as dhcpcd)
* isc-dhcp[/list]
My questions are:
1. What DHCP comes standard with Raspbian?
2. I would like to stick with isc-dhcp, what can and should I remove?
3. How do I remove them?
