similar to: u32 hashing filter - deletion problem!

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I''ve written a minimal sort of Perl module that dynamically creates and destroys traffic control rules for specific IPs. I''m currently using it for a user bandwidth control application at a client site. The module essentially gets Ethernet device(s), IP address and in/out speeds as input and dynamically creates classes, queues

Does anyone have experience with using HTB to shape traffic for several thousands of users, each with a class of their own? The LARTC HOWTO has a section about setting up hashed filters to deal with "many" classes. Has anyone used that setup? -- ams

Hi, currently I''m using 48 class with htb & very stable Is there any maximum number of class I can create in a single linux box ? I need 500 or even 1000 class for campuss network. Any help appreciated thanks & regards Tino _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

I am planning to replace our cisco 7200 core router with Linux. We currently serve around 1500 (3/4 DSL - different router) customers with probably half of them being concurrent at any given time. We have a fiber network and customers currently aren''t managed as far as how much bandwidth they can use at anytime. Therefore I have constructed a working tc qdisc Linux router as a test. It

Hey Marek, I´know that i must to works whith the INGRESS (instead of EGRESS), i´ve well formed my kernel. My others TC rules for source IP address (not for MAC address) does work fine...!!!, the problem is whith the MAC because is a not "IP PROTOCOL" and for that i must to use the "u32/u16 match" to solve it, and if i make an analogy from my others INGRESS rules applied to Src

I''m hashing on a non-octet boundary, and it doesn''t seem to be working. I''ve got this set of filters, that does work: # root tc filter add dev eth1 \ parent 1: protocol ip prio 2 \ u32 # ht tc filter add dev eth1 \ parent 1: protocol ip prio 2 \ handle 2: \ u32 divisor 256 # flow tc filter replace dev eth1 \

Hi, is it possible to use firewall mark as an u32 hash key? What i understood from the source code is that only 32-bit number inside of the packet can be used as a hash key, though fw mark can be matched using u32 match(with 2.6 kernel and recent iproute2 version). Thanks, -b42

Hi guys, Sorry if this is a little offtopic, but I was wandering what can one do to prevent/stop arp flooding ? Thanks, Alex -- This message has been scanned for viruses and dangerous content by LG-Network(http://www.lgnet.ro), and is believed to be clean.

Hi to everybody. I read some info and documentation but i still can''t find how to make this simple setup for example . I just want to make priority of certain traffic without shaping the traffic . For example SSH and RDP first priority Mail second priority WEB and FTP third And everything else last priority. What will be the simple and best way to achieve this. I will appreciate

Hi! I want to upgrade hardware on my router (iptables, htb, >1000 users). Now it is based on usual desktop PC (Intel Prescott P4 3.00 Ghz, 1 Gb RAM). The reason of hardware upgrade is growing up number of users, also we are planning to increase upstream link from 100 Mbit/s to 1 Gbit/s. Iptables rules are now optimized with ipset tool, for tc I''m using hash tables as well. So I

Hi, with the attached config my gaming ping is still +20ms, even if the line isn''t saturated..can anybody give me a hint how to get a better response time? my line: 1024/128kbit outbound: one htb qdisc for gaming (7kbps) prio 0 ceil 14kbps<- should get more traffic when needed. Htb again for irc and default. inbound: css, irc, p2p, default <- same shema as before, give css

We are currently running a production mail server using version 0.990.99.11-2 (latest RPM from RHEL/CentOS). We would like to migrate more virtual domains off our courier imap server to dovecot but the courier imap user passswords are stored in LDAP and are SSHA hashed which is not supported by our current version of dovecot (CRYPT only). >From reading the mailing lists this feature is now

Hi. Is there anyone who has understood of how u32 nexthdr addressing is supposed to work? (including the "tcp/icmp/.." matches who implicitly uses nexthdr) From reading the kernel code it apparently is using the location set by "offset at", but this seems to only be evaluated on hash parents, and only for it''s children.. I.e. the logic for u32 filter rule

Hi everyone, I have a small problem. I have my debian server setup in my home. I have setup htb that is working perfectly. The only problem I have is to control the traffic server <-> internet I have a daemon (bittorrent) and I would like to limit its download to a certail amount. How can I do that ? I have tried layer7 but it seems I''m doing something wrong in the htb script.

I'm trying to understand the method dispatch in objc_MsgSend. At some point during compilation, ascii selectors are hashed into integer SEL's. Is this hash somehow guaranteed to be unique? If so, how? If not, how are collisions handled? Is this hashing done during the link phase? Any insights/pointers to the code/documentation related to this hashing would be greatly appreciated.

The MKsetup() in unique.c throws an error if the vector to be hashed is longer than (2^32)/8: if(n < 0 || n > 536870912) /* protect against overflow to -ve */ error(_("length %d is too large for hashing"), n); I occasionally work with vectors longer than this on 64-bit builds. Would it be too much to ask that R can take advantage of all 64 bits for hashing when

Hello, I'm doing some analysis on a rather large data set. In this case, some simple commands are failing. For example, this one: > x$eventtype <- factor(x$eventtype) Error in unique.default(x) : length 1093574297 is too large for hashing ...I think this is a bug, because "hashing" should not be required for the "factor" function. Am I right? The whole column

This is intended for those interested in IceShare development.. The earlier drafts of the IceT protocol (sorry, not back on the wiki yet) used SHA1 hashes for pages. This, AFAIR, is the same that bittorrent uses for .torrent files, except ours are transfered "live" between the peer and the tracker as the data is being transfered. The first method, where the Tracker sent a seperate

Hello, I am trying to make a load balance at my box using two conections. I have compile my kernel with this patch routes-2.6.13-12.diff (tha I get from this website: http://www.linuxvirtualserver.org/~julian/#routes). The problem is that when I try to balance using weight sintaxe (i will put the script bellow) some conectios just drop. So I can enter some pages but other I could not...
