I am trying to install NFS Server to my brand new Ubuntu machine and is about to follow this article. But before that, is there any way to figure out whether it is already installed?

I am running Ubuntu 12.04

Update:-

This is what I got after running this - 

dpkg -la | grep nfs

ii  libnfsidmap2                     0.23-2                                            An nfs idmapping library
ii  nfs-common                       1:1.2.2-1ubuntu1                                  NFS support files common to client and server

And aptitude command gave me like this - 

aptitude search nfs

p   fai-nfsroot                                                                                                    - Fully Automatic Installation nfsroot package

I tried netstat command as well - 

netstat -tl | grep 2049

and nobody is listening to that as well

If you know the package's name, try dpkg -l package-name. That should list the package (with two is next to it) if it's installed, or give you an error if it isn't.

Ubuntu 13.10 (which is running in a VM here) calls its server package nfs-kernel-server. (There might be other packages or other names on older versions; looks like it used to be called knfs. But nfs-kernel-server is the recommended package.)

If you're using a decent package management program, though (like Synaptic, which i highly recommend), you can just type some stuff into a search box and it'll find matches for you -- at which point you can set it to install (unless you're installing from source, which i don't recommend if you can get by with the version Ubuntu includes with that release).

  • I don't know the package name.. I was about to install it by following the above article but thought to check it before installing it again.. – AKIWEB Nov 25 '13 at 23:22
  • It looks like `nfs-kernel-server` or (for older versions) `knfs`, plus whatever dependencies get added to the list, would be enough to give you a working NFS server. – cHao Nov 25 '13 at 23:27

dpkg -la | grep nfs

will list all packages that you have installed and whose name includes nfs.

aptitude search nfs

will tell you that the nfs server package is called nfs-server. Since you are not seeing that, I'd say you don't have it installed.

To be safe, also do:

netstat -tl | grep 2049

to check whether anyone is already listening on the nfs port.

  • this is what I got when I executed the above command - `ii ftp 0.17-23 The FTP client ` – AKIWEB Nov 25 '13 at 23:19
  • @TrekkieTechieT-T: That was just an example. For an NFS server, of course, you'd grep for "nfs". – cHao Nov 25 '13 at 23:20
  • Sorry, yes, I misread at first. Corrected my answer to nfs. – Christian Fritz Nov 25 '13 at 23:22
  • oops.. this is what I got - `ii libnfsidmap2 0.23-2 An nfs idmapping library ii nfs-common 1:1.2.2-1ubuntu1 NFS support files common to client and server ` – AKIWEB Nov 25 '13 at 23:22
  • I just have updated the question with more details and nobody is listening to that port as well which means I don't have it installed right? – AKIWEB Nov 25 '13 at 23:29
  • @TrekkieTechieT-T: Yeah, from the looks of it, it appears you don't have the server stuff installed. – cHao Nov 25 '13 at 23:33
