unable to create ubuntu home network

TheOne...More · 08-14-2013, 02:01 PM

hi all

i'm trying to make an home network between a couple of ubuntu boxes through ethernet. i installed samba and enabled sharing of some folders yet the windows network folder shows only local folders to the box.

any ideas what i did wrong?

thanx

Your post is a little confusing. You starting saying you are trying to make a home network between Ubuntu systems and then mention windows. Is it multiple Ubuntu computers and windows? or just Ubuntu? nfs is usually used between Linux machines.

you need more details then what you provided.

why are you using SAMBA to connect a couple of LINUX computers? never use an interpreter when you can use native. for connecting Linux to Linux shares use NFS.

2nd you are mixing connecting a couple of Ubuntu (linux) boxes through ethernet and Windows network folders, so what is it? are you trying to use Linux to connect/share files with MS Windows, or Linux to Linux only, or a combination of the two?

You have not posted any error messages, nor have you posted exactly the steps you have taken to get any kind of sharing working.

details details details my friend. the more the better and the better the response will be.

sorry my bad.

yes what i'm trying to do is connecting ubuntu boxes only, but i used samba cause when ever i googled for creating ubuntu home network, samba kept haunting the results, i just followed through.

but if there is a simpler way please tell me how.

so as to what the steps i followed. i tryed the gui simple way at first, i select the folders i wanted to share, right clicked, chose shares, enabled sharing, a popup dialog box appeared asking whether i wanted to install samba or not, i agread and it installed samba. after that i installed samba system configuration gui tool. i set on each box the user to ubuntu, and chose the folders i wanted to share, and restarted both boxes.

what happened is what i told before, in each box only the local shared folders appeared, and not the other box.

Unless you plan on expanding this share to Windows, you should abandon Samba and switch to NFS. It's native, much better supported, and is much easier to configure.

In my opinion you should also try to avoid using GUIs for this kind of thing. They rarely set the system up properly, and just end up garbling the config files.

For NFS, you'll need to make sure it's allowed in the firewall and started on boot. You'll need to make sure your /etc/hosts.allow and /etc/hosts.deny are not blocking the other machine, then just set up /etc/exports with which directories you want to export and to who, and then set up /etc/fstab on the other machine to automatically mount the shared directory wherever you want.

The end result is a directory on the client machine that acts and functions as though it's native, when it's really a remote mount from the server machine.

thank you for offering your answer, i would like to know also what if i wanted to expand the network to contain windows. what did i mess up in the steps i explained about samba installation.

Hard to say. As I mentioned before:

You'll need to dive into the config files (samba, firewall, etc.) to see what the GUI did wrong and fix it.

is there an easier way than samba to get windows into the network?

you are going to want to setup NFS server on each of the systems that you have a folder to share across the LAN.

creating /etc/exports for each system to share out the specific path.

on the other systems either use systemd or autofs to mount the shares depending on what vs. of Ubuntu you are running. I have no clue how much of systemd automount is enabled in Ubuntu. I do know you can get autofs up and running with ease in Ubuntu.

The things to google and try:

1. setting up NFS vs 4 server on Ubuntu
2. configure firewall and static ports for NFS vs 4 server in Ubuntu
3. proper configuration for /etc/exports for NFS vs 4 in Ubuntu
4. howto configure autofs for NFS shares Ubuntu.
4a. howto configure automount with systemd in Ubuntu...

Note finding info on systemd automount is going to take a lot more work then autofs. You might want to just use autofs for now as it just works and is very simple to configure.

Once you read up on those steps and start putting things together post here if you have issues.

remember to use code flags. here is my NFS server configuration and /etc/exports as well as an autofs from one of my workstations. Granted im no using Ubuntu, but the basics should be close enough.

here is the workstation autofs configuration:

Code:

[root@localhost ~]# cat /etc/auto.master
#
# Sample auto.master file
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# For details of the format look at autofs(5).
#
/misc	/etc/auto.misc
#
# NOTE: mounts done from a hosts map will be mounted with the
#	"nosuid" and "nodev" options unless the "suid" and "dev"
#	options are explicitly given.
#
/net	-hosts
#
# Include /etc/auto.master.d/*.autofs
#
+dir:/etc/auto.master.d
#
# Include central master map if it can be found using
# nsswitch sources.
#
# Note that if there are entries for /net or /misc (as
# above) in the included master map any keys that are the
# same will not be seen as the first read key seen takes
# precedence.
#
+auto.master
/home/user/NFS	/etc/auto.NFS	--timeout=600	--ghost
[root@localhost ~]# cat /etc/auto.NFS
Shares	-rw,soft,intr,bg,rsize=8192,wsize=8192	server:/exports/

here is the /etc/exports from my NFS server:

Code:

[user@server ~]$ cat /etc/exports 
#
#	/etc/exports

#	NFS4
/exports *(rw,insecure,subtree_check,crossmnt,fsid=0)

#	NFSv3
/exports/centos/public *(rw,insecure,no_subtree_check,fsid=3010)
/exports/NFS_TV_Shows *(rw,insecure,no_subtree_check,fsid=3020)

3 things of note in my exports:

1. note the fsid. each export has to have its own unique number. you assign these numbers.
2. note i have both NFSv3 and NFS4 in my exports due to the fact I have Apple Mac OSx in my LAN.
3. note unless you are running OSx in your LAN, there is no need for the insecure option in your exports.

here is my iptables:

Code:

[root@centos ~]# cat /etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter

note the specific ports.

again this is specific to CentOS, im sure it will be similar for Ubuntu.

SAMBA is for connecting MS to Linux. Samba is easy, do not bother with any GUI tools for configuring either Samba or NFS. they are not that hard to edit by hand and you will both learn more and be able to properly configure your system.

thank you guys.

good luck, and remember to post back with both questions and success stories. when you are successful post so others in your boat can learn from you. its a wonderful thing.
