From: Colin Ian King <colin.king at canonical.com> Simply mmap'ing /dev/dri/card0 repeatedly will spam the kernel log with qxl_mmap information messages.

Gang, For months now, we're all seeing repeated bruteforce attempts on SSH. I've configured my pf install to ratelimit TCP connections to port 22 and to automatically add IP-addresses that connect too fast to a table that's filtered: table <lamers> { } block quick from <lamers> to any pass in quick on $ext_if inet proto tcp from any to ($ext_if) port 22 modulate

A user reported getting spammed when moving to 3.0 by this message. Since we switched to the normal checksumming infrastructure all old free space caches will be wrong and need to be regenerated so people are likely to see this message a lot, so ratelimit it so it doesn''t fill up their logs and freak them out.

I have a question about the function of line feeds/carriage returns in an all linux (R, vi to write scripts) environment. In my scripts I have a few functions, using { or ( to wrap commands on the next line. Usually this is fine, but sometimes R appears confused by line wrappings (more likely of course it is me who is confused). I tried ';' to explictly break the line, but no dice. An

Building today in git - kernel 2.6.32 (git) + nouveau (git). Failed as nouveau_irq.c doesn't include <linux/ratelimit.h> Added the include to nouveau_irq.c and was able to compile... not sure that's where it ought to go.

Hi, Please advise how to use Response Rate Limiting on a server which has multiple NSD server processes (nsd.conf server section has server-count > 1). We have a problem with NSD v3.2.16 repeatedly unblocking and blocking again a single source which is flooding positive queries at a ~steady 700 qps rate. rrl-ratelimit setting is the default 200 qps. The unblock-block happens multiple times

Dear NSD users, Here is the release candidate for NSD 3.2.15. This comes with ILNP support, NSD-RRL and different TSIG initialization (it fails if it can't find no suitable algorithms, instead of can't find 'one of the'). Plus some bugfixes. The NSD-RRL implementation is based on the work by Vixie and Schryver. However, because of the code-diversity argument that is at the basis

Dear Steve and *.* e1r2 developers and users, now MFCR2 is successfully installed! many thanks for your help. I'm living in Argelia (north africa). I have configure my MFCR2 according argentina R2 settigs : the test call run perfectly (only warnings and I think that is just debug). but I have many problems and when I run Asterisk-MFCR2. generally in the begging no errors occur. after

Hello, We have a number of systems running KM400 chipsets from VIA (Socket A/462). Two different models have produced the same results -- DFI KM400-MLV and MSI KM4M-V. When a /sbin/reboot or /sbin/shutdown -r now is issued, the system does everything you would expect from a reboot, but when it gets to Rebooting System, it hangs and requires a power cycle. The logs do not indicate anything

I think it would be nice to be able to rate limit an action, too.. suppose I have an action named Accept_good_source : ACCEPT - - tcp - 1024:65535 ACCEPT - - udp - 1024:65535 and that i want to use it in an action called AllowCVS, i can''t limit the cvs usage, but only the general use of Accept_good_source... same goes for userset... as each rule will give one iptables command, I

Hello, I'm trying to setup an Asterix PBX solution in our office. We plan to have 5 active lines open available at any point in time. We'd like to use VoIP Phones, and possibly Software Based phone (*NIX/Windows enviroment). I was researching the various cards and I think I'd want to go with the Digium TDM40B - 4-port. However, I can't figure the differences between FXS &

People are proposing rate-limiting built into BIND, to defend against some DoS attackes (a proposal <http://fanf.livejournal.com/122111.html> and its implementation <https://github.com/fanf2/bind-9/blob/master/doc/misc/ratelimiting>). What is the current thinking for NSD? (It is a truly open question, do not take it as "this guy requires rate-limiting in NSD".)

Hello list, I'd like to know if there is a function that tells in which package is a given function. Something like : which.package("lda") [1] "MASS" Thank you.
