Greetings -- in the "Linux Advanced Routing & Traffic Control HOWTO" chapter 14.1 on bfifo/pfifo it says that: "you can use this qdisc to determine the backlog on your interface". But it does not say exactly how. Command [#tc -s qdisc ls] outputs the number of packets sent so far but it does not output any info about the backlog. My first question is whether a command exists that provides info about the backlog. My second question is whether a sys...

What techniques and tools do you use to manage your feature backlogs? It could be as low tech as a post-it note, TODO file in your Rails project tree, or as high tech as a web-based collaborative tool. Thanks, Mark

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the

Hi all, First, let me say I''ve been most impressed with how quickly and professionally people on this list ask and answer questions. Next, let me say that with which I need help is properly configuring strict PQ, and gathering certain stats. Specifically: - I need to create a priority queue with four queues (let''s say they are of high, medium, normal, and low priority) - I

...completed its part of the TCP handshake and is ready to exchange data over the socket. This problem reveals itself in situations where 64 or more client nodes issue concurrent ssh requests to the server. Looking at sshd.c, I noticed that the daemon's listen socket is created with a very short backlog value (5), and we are certain that this is the cause of our problem. Is there a reason for using such a small value, as opposed to setting the backlog to SOMAXCONN? We need to scale our application to clusters with thousands of nodes and we are trying to determine whether openssh would permit us t...

With this i can cause a temporary DoS on SSHd preventing any user to log-on. ( sometimes the real connection is closed , somethimes it does't response at all ( there is no SYN-ACK ).
