Hi folk,
I am trying to get iptables working on a samba server but find it is
blocking something that prevents the windoze clients from being able to
access the share.
here are the bits from iptables:
> # nmb provided netbios-ns
> -A RH-Firewall-1-INPUT -p udp -m udp -s 192.168.230.100/24 -i eth1
> --dport 137 -j ACCEPT
> # nmb provided netbios-dgm
> -A RH-Firewall-1-INPUT -p udp -m udp -s 192.168.230.100/24 -i eth1
> --dport 138 -j ACCEPT
> # Samba
> -A RH-Firewall-1-INPUT -p tcp -m tcp -m state -s 192.168.230.100/24 -i
> eth1 --dport 135 --state NEW -j ACCEPT
> # smb provided netbios-ssn
> -A RH-Firewall-1-INPUT -p tcp -m tcp -m state -s 192.168.230.100/24 -i
> eth1 --dport 139 --state NEW -j ACCEPT
> # smb provided microsoft-ds
> -A RH-Firewall-1-INPUT -p tcp -m tcp -m state -s 192.168.230.100/24 -i
> eth1 --dport 445 --state NEW -j ACCEPT
so as far as I can tell this should provide access to the required services.
BTW the server has two NICs; 100Mb is eth0 at 192.168.230.230 and
connects to the router with internet/NAT firewall; 1Gb is eth1 at
192.168.230.232 and this connects to a G ethernet switch that has the
windoze clients.
The smb.conf is as follows:
[global]
workgroup = NDG
netbios name = SAMBA
netbios aliases = Samba
server string = Samba Server Version %v
interfaces = lo, eth1, 192.168.230.232
bind interfaces only = Yes
security = DOMAIN
obey pam restrictions = Yes
passdb backend = tdbsam
pam password change = Yes
log file = /var/log/samba/%m.log
max log size = 50
load printers = No
add user script = /usr/sbin/useradd "%u" -n -g users
delete user script = /usr/sbin/userdel "%u"
add group script = /usr/sbin/groupadd "%g"
delete group script = /usr/sbin/groupdel "%g"
delete user from group script = /usr/sbin/userdel "%u" "%g"
add machine script = /usr/sbin/useradd -n -c "Workstation (%u)"
-M -d /nohome -s /bin/false "%u"
logon path =

os level = 32
preferred master = Yes
domain master = Yes
dns proxy = No
wins support = Yes
ldap ssl = no
create mask = 0664
directory mask = 0775
hosts allow = 127., 192.168.230., 192.168.231.
case sensitive = Yes
browseable = No
available = No
wide links = No
dont descend = /
[homes]
comment = Home Directories
valid users = %S
read only = No
browseable = Yes
available = Yes
[NDG]
comment = NDG files
path = /NDG
write list = @NDGstaff, @birdseye
read only = No
browseable = Yes
available = Yes
I found that making the rule for port 139 ignore the eth port (i.e.
remove the -i eth1) allowed things to work better, but do not want this
to be the case as I do not want the eth0 interface to be used for this
traffic.
looking at netstat -l -n shows only lo and eth1 listening on port 139,
so how is this failing to work??
Any ideas?
Thanks
Rob
