similar to: Watchdog timer and packet enqueuing

Hi there! I''ve using HTB for a while and now I an faced with a ''problem''. How hierarchical is HTB? Let''s say I have this 3 layer HTB setup: root class 1: (rate=100, ceil=100) 1: children classes 1:10 (30,100) and 1:20 (70,100) 1:10 children classes 1:100 (10,100) and 1:101 (20,100) 1:20 children classes 1:200 (30,100) and 1:201 (70,100) I managed to have

Hi all, I've got a Portwell NANO-6060 board I am testing out for potential use in a project of ours. One of the nice features of this board, beyond nice NICs, is that it has a hardware watchdog timer. The problem is that I don't get a /dev/watchdog device file. I know the hardware works, because when I enable it in BIOS, the box will reboot after the timer expires. However,

I''ve been reading the Linux Advanced Routing & Traffic Control Howto and it''s well put together but I''ve a few questions about the mechanism. I dont'' think that I''d have any questions if I just wanted to know how to configure the Shaping method but I''m trying to get into the nuts and bolts. Basically I''m trying to find out the

Hello! I like to announce sch_ooo, a new queue discipline that, attached to a class (or a device, as root) reorder the packets that pass by delaying some. Example: tc qdisc add dev eth0 root ooo limit 100 gap 4 wait 1100 This queue will create a pfifo with limit 100 and will delay every 4th packet with 1100ms. An stream of 6 packets like this: 1 2 3 4 5 6, generated by ping will be reordered

Hi you all, I am reading the Rolling with Rails article, by Curt Hibbs. In the beginning, when he is explaining how to install the MySQL Server, he comments we mustn''t set up any account cause MySQL uses an authentication algorithm that is not compatible with the current version of Rails. Is there any way to avoid this and establish an account with its password? (I am using MySQL 5.0

Greg: This patch series removes the get_driver() and put_driver() routines from the kernel. Those routines don''t do anything useful. Their comments say that they increment and decrement the driver''s reference count, just like get_device()/put_device() and a lot of other utility routines. But a struct driver is _not_ like a struct device! It resembles a piece of code more

We use spinlock to synchronize the work list now which may cause unnecessary contentions. So this patch switch to use llist to remove this contention. Pktgen tests shows about 5% improvement: Before: ~1300000 pps After: ~1370000 pps Signed-off-by: Jason Wang <jasowang at redhat.com> --- drivers/vhost/vhost.c | 52 +++++++++++++++++++++++++-------------------------- drivers/vhost/vhost.h |

Hi all, I''m looking into installing Ruby on Rails on my dedicated server which is RH Linux with a traditional PHP/MySQL/Apache configuration. I''m not an expert Linux user, but I can hold my own. My server hosts around 15 domains with websites of various complexity, some shops, some CMS, some completely flat. I''m looking for a tutorial explaining how to install Ruby

lartc-request,hello! 　　 I find a line in tbf_change() in sch_tbf.c: ptab = xchg(&q->P_tab, ptab); Can I consider that the pointers are exchanged between q->P_tab and ptab? as following: prev=q->R_tab; q->R_tab = rtab; rtab = prev; Is my understanding righ? ======= 2002-03-23 12:01:00 you wrote:======= >Send LARTC mailing list

This feels more like a question to ask the core list, forgive me if I trespass. I''ve been trying to help one of my cow orkers get through a sticky problem. He''s got a fairly complex nested form to update a model and its children. He''s started adding some validations, and we''ve encountered a number of issues: First he had a validation on one of the child

Hi Corentin, I am fine with this proposal: it is generic enough and I have been able to test and run the crypto engine with aead_request without changing any single line of code. This is what I need to be able to send the AEAD extension of the stm32-cryp driver (successfully tested with your engine upgrade proposal). I have also tested the stm32-hash patch. Note that stm32-cryp (new

Okay, here is a very simple QOS scheduler that delays packets for 2.6. It is good for testing, and might be useful for people who want to put some class of traffic into a "penalty box". Alexey''s tc command is really easy to extend to new disciplines. There is a version which knows about this scheduler at: http://developer.osdl.org/shemminger/tcp/iproute2-delay.tar.bz2 The
