Everyone knows that unladen traceroutes display faster response times. -- --

Email security issues
by Adi Linden 10 Nov '03

10 Nov '03

Hi, Is there a place to discuss and find solutions for email related security issues? I've just receives a nice email from my banker (ok, it claims to be from my banker) asking me to visit my banks website and confirm my email address. This email is by far the most convincing piece of fraud I received to date so far. The URL loads up the bank page plus a popup provoding a login. Looking at the source of the popup it revels that it is positively not a legit source and most likely used to harvest peoples access information. Thoughts? Adi

.iq info update requests
by Eric Brunner-Williams in Portland Maine 10 Nov '03

10 Nov '03

Howdy folks, A .eu researcher asked about my .iq data, so I've put that data back up. I haven't spent any time keeping it current, or expanding it, but I will if people actually send me data. Some of you have, or have expressed an interest in doing something of marginal or greater utility, or are doing something real for a similar eventual operator. Some of you will recall some boneheaded proposal to snag the ccTLD under a theory of "doing good", and selling off witty names like "lacking.iq", with some of the proceeds going to the Home for Little Lost NOCs. That's not my idea. I'd like ICANN to get real or go home on the issue of seizure-by-operator-arrest of a ccTLD, and I'd like the eventual academic operator of the .iq ccTLD to have data, to use or ignore, as they see fit, which usefully functions as-is, for some definition of "useful". So, data, data, data. Please. Forward where you think interest or data exists. Eric

Ex PSI legacy .us domains inactive
by Christopher X. Candreva 10 Nov '03

10 Nov '03

Over the weekend a customer of mine had his legacy .us domain under .rye.ny.us stop working, as it is no longer in the root servers. After doing some checking, a whois on rye.ny.us shows it as inactive. The customer found this list of .us delegations: http://www.neustar.us/delegated_managers/delegated_subdomains.txt A random check shows every domain listed as being with psi.net as inactive. I'm about to write a little script to check all the psi domains in that list. This is basicly a heads-up if anyone else has a domain that might be in the same catagory, or if someone from Neustar is listening, the customer's attempts to contact them so far haven't been fruitfull. The PSI deleted domains are mostly NY cities. ========================================================== Chris Candreva -- chris(a)westnet.com -- (914) 967-7816 WestNet Internet Services of Westchester http://www.westnet.com/

Does anyone know if Telcove is blocking any 135 ports or 139? I have a class that is trying to access our network from this ISP and they are unable to connect. Everyone else is working fine.

And for this same reason, we ask for the resume's in "Plain ASCII" If they simply export their Word doc, it gets deleted as the formatting is terrible. A good geek/sysadmin understands the importance of a well formatted ASCII file. --Mike--

This may be stupid but..
by Fisher, Shawn 10 Nov '03

If this question is inappropriate for this list I apoligize in advance. I have several open engineering positions that I am trying to fill without the use of a recruiter. My thoughts on using a recruiter is they end up extracting a fee from the employer that would be better put to the future employee. My question, what is the most effective way to recruit quality engineers? Does anyone have experience or opinions to share? TIA, Shawn

>>talking about ICMP echos with varying TTL and routers sending back >>ICMP echo-replies. I wanted to end the interview and hire him on the >If that would be the criteria, wouldn´t the acceptable answer involve >UDP packets and >ICMP time exceeded? (not counting windows way of doing traceroute) Little details like that can be sorted out later by education. In fact, the individual that I'm thinking of may have mentioned UDP packets. The point is that the answer shows the kind of detailed understanding of the network that you want in a network engineer. This guy wasn't just a user of tools that do stuff, he understood what was happening inside the network layers themselves. There are lots of people who know how to use traceroute or Infovista but you wouldn't want them logging into your core routers for troubleshooting. --Michael Dillon
