windows网络上的centos iptables

我有一台运行Centos的机器，它连接到windows网络。当我试图查看网络时，出现错误“无法从服务器连接共享列表”。一旦我关掉iptables，一切都很好。我怎样才能解决这个问题。我当前的iptables配置是

# Generated by iptables-save v1.4.7 on Sat Nov 16 11:06:35 2013
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [6:360]

您可以为被拒绝的流量临时添加日志规则：

-A INPUT -j LOG --log-prefix "Rejected: "

在申请前：

-A INPUT -j REJECT --reject-with icmp-host-prohibited

---

您将看到哪些流量被拒绝

a]首先记录丢弃的ip表，例如

#----------
# Logs to messages.log
#----------
-A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: INPUT " --log-level 4
-A OUTPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: OUTPUT " --log-level 4
-A FORWARD -m limit --limit 5/min -j LOG --log-prefix "iptables denied: FORWARD " --log-level 4

b] 从消息中删除表的尾部

tomas@raspirarium:~ $ tail -f /var/log/messages |grep "iptables denied"

c] 在message.log中动态写入ip表规则，超出拒绝的规则，如下面的示例所示

#----------
# Windows Samba
#----------
# incoming request
-A INPUT -i eth0 -p tcp -s 192.168.79.0/24 -m multiport --dports 139,445 -m state --state NEW,ESTABLISHED -j ACCEPT
-A OUTPUT -o eth0 -p tcp -d 192.168.79.0/24 -m multiport --sports 1024:65535 -m state --state ESTABLISHED -j ACCEPT
# outgoing laso handler
-A OUTPUT -o eth0 -p tcp -s 192.168.79.0/24 -m multiport --dports 139,445 -m state --state NEW,ESTABLISHED -j ACCEPT
-A INPUT -i eth0 -p tcp -s 192.168.79.0/24 -m multiport --sports 1024:65535 -m state --state ESTABLISHED -j ACCEPT
