Linux – Share Folders on OpenSUSE 13.1 Using SAMBA (Share Not Working)

linuxnetwork-sharesopensusesamba

Gentlemen,

I tried all ways to share folders on OpenSUSE 13.1 using SAMBA, but without success. Frankly, I do not know what to do to resolve this situation.

Among my actions are taken…

Stop the firewall
Do the procedures set out in :

I can make the server work normally and without error including its parameters (testparm), but I can not access it from another machine (Linux or Windows) using "smb://[MACHINE_IP]/[SHARE_NAME]" or "\[MACHINE_IP][SHARE_NAME]"! I also tested using the machine itself.

Nothing seems to make samba work. What was supposed to be a simple and ordinary thing in other distributions became a nightmare. I'm beginning to think that this is a problem in the distribution itself!

I can not imagine what can be done! = /

Please help me!

Thanks in advance!

More!

Below I put the outputs of the smbd and nmbd logs!

These logs covering the time when I start the service to when I try to access the share from another computer!

Conclusions so far:

Some peculiarity of the corporate network where I work is blocking access to Samba OpenSUSE 13.1, because in my home network samba works perfectly.

The OpenSUSE 13.1 is running on a VMWare using NAT network. In my view there should not be any interference from the outside network, since I'm using NAT.

I have an other virtual machine running Linux Mint 16 KDE on VMWare using NAT. Samba works perfectly in both my home network and the corporate network which leads me to believe that this is some configuration to be taken in the openSUSE 13.1 to make samba work.

Below I put the output from running "smbclient" over my host to both virtual machines:

smbclient //172.16.124.141/share -N -U'brlight%brlight'
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.6.18]
smb: \>

smbclient //172.16.124.136/share -N -U'brlight%brlight'
protocol negotiation failed: NT_STATUS_IO_TIMEOUT

Centos – Samba + Centos (Share not working)

Samba shares need both users and settings. I'm sure you already have CentOS users, but do you also have Samba users setup?

smbpasswd -a joe

you can also add the following line to your share definitions

[ruby]
valid users = joe randi insert-samba-user-here

Oh and make sure you reload samba via

service smb restart

(Note, most code taken from: http://www.cyberciti.biz/faq/adding-a-user-to-a-samba-smb-share/ )

Linux – need iptables rule to accept all incoming traffic

Run the following. It'll insert the rule at the top of your iptables and will allow all traffic unless subsequently handled by another rule.

iptables -I INPUT -j ACCEPT

You can also flush your entire iptables setup with the following:

iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT

If you flush it, you might want to run something like:

iptables -A INPUT -i lo -j ACCEPT -m comment --comment "Allow all loopback traffic"
iptables -A INPUT ! -i lo -d 127.0.0.0/8 -j REJECT -m comment --comment "Drop all traffic to 127 that doesn't use lo"
iptables -A OUTPUT -j ACCEPT -m comment --comment "Accept all outgoing"
iptables -A INPUT -j ACCEPT -m comment --comment "Accept all incoming"
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -m comment --comment "Allow all incoming on established connections"
iptables -A INPUT -j REJECT -m comment --comment "Reject all incoming"
iptables -A FORWARD -j REJECT -m comment --comment "Reject all forwarded"

If you want to be a bit safer with your traffic, don't use the accept all incoming rule, or remove it with "iptables -D INPUT -j ACCEPT -m comment --comment "Accept all incoming"", and add more specific rules like:

iptables -I INPUT -p tcp --dport 80 -j ACCEPT -m comment --comment "Allow HTTP"
iptables -I INPUT -p tcp --dport 443 -j ACCEPT -m comment --comment "Allow HTTPS"
iptables -I INPUT -p tcp -m state --state NEW --dport 22 -j ACCEPT -m comment --comment "Allow SSH"
iptables -I INPUT -p tcp --dport 8071:8079 -j ACCEPT -m comment --comment "Allow torrents"

NOTE: They need to be above the 2 reject rules at the bottom, so use I to insert them at the top. Or if you're anal like me, use "iptables -nL --line-numbers" to get the line numbers, then use "iptables -I INPUT ..." to insert a rule at a specific line number.

Finally, save your work with:

iptables-save > /etc/network/iptables.rules #Or wherever your iptables.rules file is
