If I sudo firestarter and then hit the active connections, in the terminal window I get the following error repeatedly until I stop the active connection display. Error reading /proc/net/ip_conntrack: No such file or directory I look in /proc/net and there is no such file. Suggestions on the web state that I should I check that conntrack is installed and appearently should be, to be able to do the modprobe command to get the file. so I do sudo apt-get install conntrack which install just fine then I do sudo modprobe ip_conntrack and it does not complain but the is no file ip_conntrack file created.

Also affects distribution/package Nominate for series Bug Description Binary package hint: cutter It appears, that cutter has some unresolved dependencies, that apt does *not* know about. Using cutter after a normal https://bugs.launchpad.net/bugs/240147 installation leads to the following error message. Though I don't fully understand its meaning, I'm quite sure it is a compatibility problem worth fixing. Console output of cutter: $ cutter usage: cutter ip [ port [ ip [ port ] ] ] $ sudo cutter 172.16.3.104 openning /proc/net/ip_conntrack: No such file or directory Best regards, Frederik Braun P.S.: It is stated in the man page, that cutter has been developed for and tested on ipcop and red hat linux - the author should be informed if we manage to get it working on ubuntu. P.P.S.: Report based on Ubuntu 8.04 (hardy heron) and cutter 1.03 WORKAROUND: For Ubuntu versions up to the year 2010 with kernel versions below 3.5.x, this problem can be circumvented by either manually loading the kernel module "ip_conntrack" either with "sudo modprobe ip_conntrack" or by adding a line "ip_conntrack" to the /etc/modules file and reboot.

If you find any error or imprecision in this document, please send an email to the author, it will be appreciated.In this document, the author assumes that the reader is familiar with firewalling concepts and iptables in general. If this is not your case, I suggest you to read the iptables documentation before going ahead. Moreover, the reader must also understand the difference between stateful and stateless firewalls. If this is not your case, I strongly suggest you to read the article Netfilter's Connection Tracking System published in :login; the USENIX magazine. That document contains a general description that should help to clarify the concepts.If you do not fulfill the previous requirements, this documentation is likely to be a source of frustration. Probably, you wonder why I'm insisting on these prerequisites too much, the fact is that if your iptables rule-set is stateless, it is very likely that the conntrack-tools will not be of any help for you. You have been warned!Chapter 2. What are the conntrack-tools?The conntrack-tools are a set of free software tools for GNU/Linux that allow system administrators interact, from user-spa
