Fibre Optic / Laser Safety with Single Mode Fibre
by Mark Foster 25 Jul '06

25 Jul '06

G'day guys, Have been doing a bit of research in the area of Laser Safety, we're looking at buying some new continuity-type testers for fibre (Model is OVF-1 Visible Fault Locator, as I gather it - A google gave me http://www.butlertech.ie/products/pdfs/ovf1.pdf) and one issue that was raised was that of safety when looking down a fibre line. Especially given that some of our newer technicians particularly, are OK with networking hardware but have relatively low levels of experience with Fibre. So in the interests of safety and best practise i'm looking at what kit we should have to safely troubleshoot fibre runs at a basic level (eg, validate continuity of a fibre run / clearly identify what goes where. Not talking full fibre loss analysis or anything at this stage - initial solution is for our computer techs, not our cabling specialists.). Multimode stuff is less of an issue, being LED driven, but Single Mode is a different can of worms, especially given that its often outside the visible spectrum. What do the players on here use? Laser filter goggles or somesuch I presume? Any brands or types reccomended / preferred? Of course due care should be taken to make sure theres no active laser emmitters on the other end of the feed, but beyond that, nice to be protected. Recommendations from the floor? Cheers Mark. (All thoughts/comments are in my personal opinion, this is largely a personal enquiry i'm making off my own bat, out of interest...)

Xtra filter email with blank From, To or Subject
by Dave Green 25 Jul '06

25 Jul '06

I started having problems some weeks back with Xtra mailboxes not receiving mail from a number of lists that we send. After a bit of troubleshooting our end, a query to Xtra helpdesk revealed that they now filter emails that have a blank Mail From, To or Subject field (our lists have never had a from address and our email server appears to not have the facility to add one, which kinda makes it my problem but ...). Xtra said: "We have implemented a rule on our Xtra Email Servers requiring at a minimum of a From email address, To email address, and a subject to be displayed to prevent this form of Spam. If all of these are enterred into the email this will ensure continued delivery of the automated emails. The Anti-Spam filter works by checking the content and style of email content. These blank emails have hidden content in the body that appears legitimate to the Anti-Spam filter and are passed." Not sure if this is news or not, but I hadn't seen anything publicised re this change. My understanding was that blank "from" fields are valid, so filtering this type of email may break other things such as read receipts. Has this been a problem for anyone else out there? Dave

Does anyone know what happened to Telecom's Faxright service which I'm pretty sure used to be 0800 108 208 ?. It gives number disconnected at the moment.. I'm not sure if I have the number wrong or if it has been shut down.

Dear Colleague, This is to notify you that some object(s) in NZRR database which you either maintain or are listed as to-be-notified have been added, deleted or changed. These objects are used to configure the various NZIX route servers (http://nzix.net/) so you can expect the relevant servers to be reloaded in the near future. The reloading of the servers is staggered over a period of time so that if you are peering with both servers at an exchange, you can maintain at least one BGP session at all times and consequently a full set of routes. --- PREVIOUS OBJECT: route-set: AS9560:RS-ROUTES:AS9503 descr: advertised to AS9560 by FX Networks - AS9503 members: 131.203.0.0/16^16-29, 161.29.0.0/16^16-29, 161.65.0.0/16^16-29, 202.53.176.0/20^20-29, 202.174.160.0/20^20-29, 202.191.32.0/20^20-29, 202.46.176.0/21^21-29, 202.50.200.0/21^21-29, 202.78.240.0/21^21-29, 203.190.208.0/21^21-29, 202.50.52.0/22^22-29, 202.50.196.0/22^22-29, 202.59.4.0/22^22-29, 202.37.86.0/23^23-29, 202.49.80.0/23^23-29, 202.124.106.0/23^23-29, 192.88.85.0/24^24-29, 192.133.31.0/24^24-29, 202.20.97.0/24^24-29, 202.27.208.0/24^24-29, 202.36.119.0/24^24-29, 202.36.183.0/24^24-29, 202.36.226.0/24^24-29, 202.46.190.0/24^24-29, 202.50.247.0/24^24-29 admin-c: RPA1-NZRR tech-c: RPA1-NZRR notify: rpsl-admin(a)nzix.net notify: nznog(a)list.waikato.ac.nz notify: noc-minor(a)fx.net.nz mnt-by: MAINT-NZRR-NZ changed: rpsl-admin(a)nzix.net 20060629 source: NZRR REPLACED BY: route-set: AS9560:RS-ROUTES:AS9503 descr: advertised to AS9560 by FX Networks - AS9503 members: 131.203.0.0/16^16-29, 161.29.0.0/16^16-29, 161.65.0.0/16^16-29, 202.53.176.0/20^20-29, 202.174.160.0/20^20-29, 202.191.32.0/20^20-29, 210.48.160.0/20^20-29, 202.46.176.0/21^21-29, 202.50.200.0/21^21-29, 202.78.240.0/21^21-29, 203.190.208.0/21^21-29, 202.50.52.0/22^22-29, 202.50.196.0/22^22-29, 202.59.4.0/22^22-29, 202.37.86.0/23^23-29, 202.49.80.0/23^23-29, 202.124.106.0/23^23-29, 192.88.85.0/24^24-29, 192.133.31.0/24^24-29, 202.20.97.0/24^24-29, 202.27.208.0/24^24-29, 202.36.119.0/24^24-29, 202.36.183.0/24^24-29, 202.36.226.0/24^24-29, 202.46.190.0/24^24-29, 202.50.247.0/24^24-29 admin-c: RPA1-NZRR tech-c: RPA1-NZRR notify: rpsl-admin(a)nzix.net notify: nznog(a)list.waikato.ac.nz notify: noc-minor(a)fx.net.nz mnt-by: MAINT-NZRR-NZ changed: rpsl-admin(a)nzix.net 20060725 source: NZRR

Re: [nznog] SMTP Server Callbacks, the Devil or a Godsend?

In message <040c01c6af00$812193c0$de0dea3c(a)office.orcon.net.nz>, "Craig Whitmore" writes: >I have been looking into callbacks lately for SMTP (to reduce spam) and have >noticed a few things with a number of large nz sites who send out email. This is the scheme where upon receiving an inbound MAIL FROM:/RCPT TO: the mail server then connects back to the MX for the claimed domain and issues a MAIL FROM:/RCPT TO: as if it were going to send a reply? I'm pretty wary of such schemes because of the potential for looping (eg, A connects to B, B connects to A to verify, A connects to B to verify, ...), and because the "callback" action looks pretty much like an address verification probe for, eg, a spam list. (Once upon a time SMTP had a VRFY action which could be used to confirm addresses, but pretty much everyone turns that off due to abuse.) Aside from that some way of being sure the originator is a "real" address, preferably without requiring a separate connection, is a nice idea. One scheme I've seen a fairly large mail source (Yahoo? AOL? I forget) was to test for postmaster(a)domain instead, on the basis that the address should exist and at least they'd have somewhere to send reports of problems. That seems marginally less bad than trying the originator of the message. >A number of sites send from email addresses which don't exist. Including some newsletter mailouts that I'm aware of. Your (Craig's) list is by no means complete. Personally I'd be reasonable keen to see such mail refused as a general industry policy. Because they inevitably seem to send out (regularly) to large numbers of addresses which ceased to exist a long time ago, or never existed (hotmale.com, anyone?). The ones with valid sender addresses which have, eg, full mailboxse are only marginally less annoying. Especially given that automatic bounce processing systems have existed for a long time. I think using some sort of sender address verification scheme and then papering over it with a whitelist to allow those that fail to still send mail rather misses the point. But then I also think that email is virtually a lost cause these days, at least in the "anyone can forge anything" SMTP form. Ewen
