Bogus bogon?
by David Luyer 08 Jul '02

08 Jul '02

Something looks wrong here: ; host ns.eu.sun.com ns.eu.sun.com A 192.18.1.3 ; wget -q -O- http://www.cymru.com/Documents/bogon-dd.html | grep '192.18' 192.18.0.0 255.254.0.0 192.18.0.0 255.254.0.0 192.18.0.0 0.1.255.255 192.18.0.0 0.1.255.255 The bogon list references rfc2455 as mentioning 192.18.0.0/15, however the subnet is never referenced in it. In fact, no IP addresses appear to be in rfc2455, and the network seems to be a perfectly legitimate block containing two /16's (Sun, Agere) and one /24 more-specific in Sun's /16 block (mrc-apu.cam.ac.uk). Rob? An experiment in social engineering? :-) David.

Assistance with a Customer Network Staffing Support Levels
by Ryan Clark 08 Jul '02

Good Evening: I'm looking for any kind of industry benchmark data to help me justify IT head count. We're also looking for the same kind of data that you may uses in order to justify IT head count. Things like, How many engineers per device? At what point should the set up internal help desks? Number of trouble tickets per technician, Number of changes per engineer, etc.etc. Can you point me in the right direction to get this information? Thank you in advance for any help you can offer. Regards, Ryan _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

stats on spam?
by deeann mikula 08 Jul '02

08 Jul '02

can anyone point me to any current statistics on the amount of email traffic carried on the internet that is actually spam? everyone kicks around an AOL report to the FTC in 1997 stating that 1/3 of their email messages received were spam, and another by ATT labs (5-15% of their email, 1997) but i've been using those stats for a while, and i'd like to update my resources for my current paper/talk, but i've been searching around and am not having much luck. private responses are welcome, since i believe this borders on off-topic land... thanks much! deeann m.m. mikula director of operations telerama public access internet http://www.telerama.com * 412.688.3200

European packet loss average increasing
by Sean Donelan 07 Jul '02

07 Jul '02

My non-scientific measurements (i.e. pings to well known european sites) show an increase in packet loss to about 6%, the 10 day average previously was less than 1%. Neither ns.ebone.net nor auth1.ebone.net are answering queries. BGP data still looks normal KPNQwest data http://bgp.potaroo.net/as286/ So far I don't see much change in traffic levels at LINX http://www.linx.net/tools/stats/index.thtml AMS-IX graphs seem to have a glitch, or one heck of a DDOS. http://www.ams-ix.net/hugegraph.html

After all, they (name your favorite carrier) wouldn't have that nice fiber network if it weren't for all the money they borrowed. Paying the interest on the borrowed money should be treated as a normal business expense. Joe ------ End of Forwarded Message
