Samba NOT allowing access
 

Friends, I have tried very hard for the past week and a half to set up this Samba thing with no luck, about to give up! this is my smb.conf:

#Global Parameters
workgroup= LAB
netbios name=
#security= SHARE
encrypt passwords= yes

[homes]
read only= no
browseable= no

[music]
path= /data/mp3
browseable= yes
public=yes
write list= xrgm,gts18,rguisbert

[everyone]
path= /data/everyone
read only= no
browseable= yes

[apps]
path= /data/apps
browseable= yes
valid users= @admins, root, rguisbert
write list= @admins, root, rguisbert

I have being following the instructions from http://www.samba.netfirms.comwhich
gives simple process on setting up samba.

This is the error that I keep getting when trying to access Samba server:

\\XubuntuLab is not accessible. You might not have permission to use this network resource.
Network path was not found.

Im in a Computer lab in which all pcs are under the LAB workgroup name. What should I do? We are a non-profit org trying to quit Windows in order to save some $ by using Linux, but everything seems to be failing at this point. Thanks for any help....

Have you allowed ports 137,138,139 and 445 through your firewall? For example, with IPTABLES:

This is what I have:

xrgm@XubuntuLab:/$ sudo netstat -plant
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp6 0 0 :::22 :::* LISTEN 4680/sshd

How do you add those values to the IP tables? Thanks..

The Ubuntu Firewall Documentation has the information you need.

I still get the same error message and this what I have after following your steps:

xrgm@XubuntuLab:~$ sudo netstat -plant

I also tried using Firestarter and I did Allowed service:
Samba(SMB) on port 137-139 445 For everyone

Please help me I'm NOT giving up!!
