sflow proxy/multiplexer
by Julian Rutz 18 Jun '13

18 Jun '13

Hi there, Maybe some of you folks can give me a hint on this... I do have a linux box which is receiving sflow data from routers/switches/etc. I want this box to forward the sflow data to two or three other hosts. So I am looking for a "decent" sflow proxy/multiplexer. Any suggestions are welcome - preferably opensource :) Thanks in advance. Cheers, Julian

need SNMP devices for Torrus demo
by Stanislav Sinyagin 01 Jun '13

01 Jun '13

greetings, Some devices that we used at the Torrus+Extopus demo are no longer available: http://demo.oetiker.torrus.net/ so, I'm looking for more devices, preferably with some real and active traffic, so that the graphs don't look boring. The interface descriptions and SNMP location and contact will be screened, and your company will be listed in the Acknowledgments section. We can poll via IPv4 or IPv6, using SNMP versions 1, 2c, and 3. Please contact me at ssinyagin(a)k-open.com thanks

IRC Network / Swinog / Link down
by bm＠imp.ch 27 May '13

27 May '13

Hi there There's an issue around that the IRC Channel #swinog is in a splitted state (Link between irc.humppa.ch and irc.swissix.ch). The reason: It seems that irc.swissix.ch NTP/date is out of sync. As soon as some1 there has fixed the Issue, the #swinog Channel will have both part of the brain again (so plz: Administrator of the server, let Marty jump back/forward to the actual time/date). Thank you + Best Regards, Boris

WG: DDOS DNS Attack by Netgear Products caused by CNAME instead of A record?
by Michael Richter 24 May '13

24 May '13

Hmm I thought it is better you'll do the rate limiting on a lower layer. It's the same fix. you give the customer x queries in y time. But with RRL I think every query is counted. With iptables you can say, just count the ANY queries. So it's more specific Freundliche Grüsse sasag Kabelkommunikation AG Michael Richter Professional Bachelor ODEC in Engineering mrichter(a)sasag.ch 052 633 01 71 ________________________________________ Von: Jeroen Massar [jeroen(a)massar.ch] Gesendet: Freitag, 24.

You want to deploy RRL. iptables is not the right location for doing this kind of stuff as you will have false positives. Please see http://www.redbarn.org/dns/ratelimits Greets, Jeroen

Privat hat er unter anderem kürzlich eine Menge Dell Blade Server zum Teil sogar auf eigene Kosten für diverse Mitglieder der Linux User Group Bern und für den Linux User Group Schweiz Verein organisiert. Es wäre super wenn sich jemand der eine Offene Stelle oder besser ein Mandat für einen Unix-/Linux Engineer kennt sich bei Ihm melden könnte. Seine Email Adresse für allfällige Fragen und Angebote wäre gigabyte1(a)gmx.net Danke im Voraus für eure Kenntnisnahme und Hilfe Freundliche Grüsse Romeo
