Hi?guys. There is a wierd problem with iptables recently, hopes somebody can help me. I have installed Centos 7.2.1511 on a bare metal Dell server these days, disabled firewalld and enabled iptables.services, and setup a group of very simple rules, as the following: # iptables-save # Generated by iptables-save v1.4.21 on Tue Apr 23 09:15:14 2019 *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT

Hello, Stephen, thank you for input. Yes, these servers have the same firewall rules, and both of them have the same problem from time to time, most of time they are good. Actually, these servers are newly installed to be used as the Glusterfs storage server, so not much data flowing at this time. >From the sysctl output, I suppose it can't be a conntrack table overflow :

Rowland, Did some editing in smb.conf that I had to reverse. Now I'm back to being able to connect with the firewall disabled. When I enable the firewall I get as far as windows network -> workgroup but no connection. I have only the rules you recommended in your last email. Louis, The information you requested is below: martin at radio:~$ dpkg -l|egrep "iptables|ufw" ii 

After doing some system work, including upgrading the Samba server to 3.0.28a from 3.0.24, upgrading the kernel to 2.6.24, and changing the firewall rulesk, the XP workstations which belong to that domain, the right click "run as ..." option is slow to bring up a dialog. The phenotype is this: right click some program (for instance, a shortcut to the "command prompt")

Hi Guys, I have tried every single rule I could into iptables but I can't register this VPS to a provider Spikko. Finally I did an iptable accept on INPUT, OUTPUT, and FORWARD, for ports 0:65000 just to test things and still I can't register to the provider. I can easily register to another provider which uses port 5060 and I can make calls. But sip show registry only show Request Sent

Hi, Over the past few days I've been trying to get a prototype working of a stateful firewall for a Virtual Machine using Libvirt's network filters. My goal is to replace the current custom Python/Java code in the Apache CloudStack [0] project by Network Filters of Libvirt. Both IPv4 and IPv6 should work, but I started off with IPv4 and I have issues with accepting back

Hello, I'm having problem setting up filtering traffic for a virtual machine managed by libvirt. Strange thing is, such a setup has been working fine for me on an older version of distro (namely, opensuse 11.3 w/updates, kernel 2.6.34, libvirt 0.8.8) but refused to work on shiny new opensuse 12.4 (kernel 3.7.10, libvirt 1.0.2). The definition of filter in question is pretty simple:

Hi, I contact you as i have difficulties to use nwfilter with KVM host. I want to implemente flow filtering between my Linux guests. I created the following filter : cat admin-dmz-internet.xml <filter name='admin-dmz-internet'> <!-- this zone is an SSH ingoing only zone --> <!-- but SSH can go to an other SSH proxy --> <filterref

Louis, Made the changes. Still unable to mount office. Firewall also blocks Thunderbird mail and maybe internet. Will check that more fully later.Any thoughts ob Tony's response? Outputs: martin at radio:/etc$ sudo apt-get install ufw Reading package lists... Done Building dependency tree Reading state information...

Yes, Try this ( copy past-able. ) ufw disable ufw reset ufw limit 22/tcp ufw allow in proto tcp from any port 389,1024:65535 to any port 1024:65535 ufw allow 139,445/tcp ufw allow 137,138/udp ufw --force enable Sorry for the late reply, but im bit busy with some servers here.
