Hi all! I am a long time lurker, but have not posted until now. My old trusted firewall machine broke a couple of weeks ago and I replaced it with a XEN domU that is using DNAT and has two interfaces. The firewall domU and the FTP server domU are both guests on the same dom0. All three machines are running Debian/etch (stable) and Shorewall has version 3.2.6. I can''t get FTP to work

This patch adds an ACM hook into the network scripts (/etc/xen/scripts). It adds iptables rules that enforce mandatory access control on network packets exchanged between virtual interfaces. If ACM is active, this patch sets the default FORWARD policy in Dom0 to DROP and adds iptables ACCEPT rules between vifs that belong to domains that are permitted to share (determined by using the

Hello everybody, I have an odd problem with iptables using a Xen bridge setup. I don''t know if it would be better to post to netfilter Mailing-List. But I hope someone here know how to solve it. If it''s OT here, please let me know. I''ll try to do a little bit ASCII-Graphics to explain the topo better: _________ ________

Hi, I''m using the same set of firewall rules of 2.0.x (sorry, I can''t remember the exact minor version) and put it to work with 2.0.9. And now I can''t do passive ftp (was working before). I see that my NEWNOTSYN is set to Yes, and the loc->net rule is blocking 1024:65535. But I believe with the ip_conntrack_ftp, the passive mode would be allowed, since

Hello I''ve setuped a bridge with iptables + layer + ipp2p + tc I don''t know how to shape passive ftp ? If I put rules on port 20, 21 or using layer 7 iptables accounting still empty ...

Hi, I just wanted to share my script with the list. I have been trying to shape outbound passive and active ftp traffic without affecting inbound and lan transfers. I have tried to do this for a long time and it seems that I have finally figured it out. Feel free to comment on the below script if there is anything that can be improved. It seems to work flawlessly so far. #!/bin/bash

Hi, I am trying to use the following script to limit my passive ftp traffic to 35KBytes. Problem is, it kill''s the entire connection on that computer. The script is running on the same machine as the ftp server. I was hoping to limit the ftp traffic, and only the ftp traffic, leaving the computer. It seems to limit everything, i tried transfering a file with samba and the whole

I am trying to mark outbound passive ftp traffic with iptables and shape it to 35KBytes. I am using the following script on the computer that runs the ftp server. It is not working correctly, it seems to limit ALL traffic. Cant file share or anything. Anyone might know what is wrong? #!/bin/bash #shaping passive ftp traffic # mark the outbound passive ftp packets on ports 50000-51000
