Installing DHCP

[Eclectica]

Hi,

I like to install a DHCP on my ubuntu version 10.04 on a virtual box.
It's an exercise from school.
We need to install DHCP from source.

I downloaded the tar file from isc.org and extract it on my desktop.
I know the steps:
Configure
make && make install

but where do i need to install this dhcp?
I know there is an option in configure (--prefix)
But i don't know where to install the dhcp.
Something like this?
user#./configure --preix /etc

Because on my excercise we have to think where we need to install the dhcp
It's not allowed to download the dhcp from apt-get...
Someone who can help me ?

thnx!

Since this is a homework question I'll give you a clue. It's the largest directory in the root of the filesystem.

Hi,
I think it's '/etc' ? but i'm not sure...

Run

du -shc /

as root in order to find out the sizes of the root folders.

[Eclectica]

root@user:/# du -shc /
du: kan geen toegang krijgen tot ‘/home/user/.gvfs’: Toegang geweigerd
du: kan geen toegang krijgen tot ‘/proc/2274/task/2274/fd/4’: Bestand of map bestaat niet
du: kan geen toegang krijgen tot ‘/proc/2274/task/2274/fdinfo/4’: Bestand of map bestaat niet
du: kan geen toegang krijgen tot ‘/proc/2274/fd/4’: Bestand of map bestaat niet
du: kan geen toegang krijgen tot ‘/proc/2274/fdinfo/4’: Bestand of map bestaat niet
2,5G	/
2,5G	totaal

It's in dutch, 'kan geen toegang krijgen tot' means 'has no access to'
'Bestand of map bestaat niet' means file or dir doesn't exist

so I have no results ...

I think I may have specified the command wrong. Try changing your directory to / and running

du -shc *

The permission denied stuff for .gvfs is to do with the FUSE filesystem as they made the decision to not allow root access by default, which is a decision I completely disagree with.

Ok thnx!

My largest directory is /usr so i need to install it in /usr ?

root@user:/# du -shc * 
6,5M	bin
16M	boot
4,0K	cdrom
2,2M	dev
15M	etc

Yes, /usr is the standard directory for installing software from source. Sometimes distros like to have additional software installed to /usr/local in order to keep it from conflicting with the system, but I rarely have any problems installing straight to /usr.

Typically programs like DHCPD should already point themselves towards /usr by simply using ./configure, but this isn't always the case with most programs. In doesn't hurt to define it and make sure, and so you should find it in /usr/sbin. Additionally I would recommend the following command for installation of DHCPD:

make LIBDIR=/usr/lib INCDIR=/usr/include install

Many thanks!

so in short
The steps:

root@user:./# ./configure --prefix /usr
root@user:./# ./make LIBDIR=/usr/lib INCIDR=/include install

Is this sufficient?

[Krendoshazin]

Just a few corrections: when using options with configure you'll need to specify the arguments with =, and so the first line should be:

./configure --prefix=/usr

Also you've misspelled INCDIR in the 'make install' line, make sure you watch out for typos. Lastly there should be a command that goes inbetween configure and make install, you've already mentioned it in your original post.
