nameserver redundancy (of debatable on-topicness)
by Joe Abley 09 Oct '02

09 Oct '02

Morning, I'm looking for an ISP with a presence in Wellington who would like to swap 5U of colo somewhere close to the WIX for something similar in Auckland, close to the APE. Gear to be colo'd is a rack-mount nameserver plus UPS plus router; traffic to the nameserver will be overwhelmingly domestic, mainly DNS, plus a tiny dribble of management traffic. Reason for looking is to increase nameserver diversity. If anybody is interested, please drop me some private mail. Thanks!

Intel HAM modem strings ?
by Simon Byrnand 07 Oct '02

07 Oct '02

Not sure if this is ontopic, but I'll give it a go anyway ;-) Does anyone know of an init string for Intel HAM based modems that will force them to connect using only V34 ? (That works ?) People on rural lines often can't get reliable connections using V90 or 56Flex, but forcing the modem to use V34 usually makes a huge improvement. For the common Rockwell and Lucent based modems its easy, for example -V90=0S38=0 for LT winmodems and +MS=V34 for most Rockwell based modems. So far I've been totally unable to find a string that actually works for the Intel HAM based modems, and they seem to be worse than other modems when it comes to not falling back automatically on poor lines. (Read: they wont even connect at all on typical rural lines where Lucent/Rockwell modems will at least get some kind of connection, albeit dodgy) Any pointers ? (Sorry if this is offtopic, but I thought it was an issue that most ISP's will have had to deal with at some time or another) Regards, Simon Byrnand iGRIN Internet - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Mailwasher (again)
by Simon Lyall 07 Oct '02

07 Oct '02

Sorry to divert people from the Microsoft bashing but I'd thought I'd bring this up again. I mentioned a few months ago about Mailwasher forging bounces, anyway I was hoping they would go away or their latest version would fix the problem but it doesn't appear that way. Checking our outgoing queues around 50% of emails waiting to go out appear to be mailwasher forgeries ( bounces from our mail servers are elsewhere) and I'm getting a little worried. I really try hard to get customer email delivered and I don't what "normal" email to get delayed when it gets stuck behind mailwasher junk. Just wondering what others are doing? Private email is okay. I'm trying to avoid blocking or deleting them if I can. One suggestion was to forward them all to feedback(a)mailwasher.net :) . The other problem is that it is fairly hard to actually pick these messages out from others in the queue safely. Maybe I can sic the fraud squad on Mr Bolton for forging my email address. FDrom their FAQ: Q. How does MailWasher bounce messages? A. MailWasher uses an algorithm to determine the best route to send the bounced message back (from, reply to, return path) and actually sends the bounce back via your isp's postmaster, so it looks exactly like it has come from your isp and not from you at your address. If the spammer has used a fake address, then your bounce message will itself be bounced back to the postmaster and you won't receive the bounced bounce email. -- Simon Lyall. | Newsmaster | Work: simon.lyall(a)ihug.co.nz Senior Network/System Admin | Postmaster | Home: simon(a)darkmere.gen.nz ihug, Auckland, NZ | Asst Doorman | Web: http://www.darkmere.gen.nz - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Most newsreaders I've seen that have email integrated allow you to set a different email address for posting to the news group than for sending email. Even Outlook Express does this. People writing newsreaders know that fake address are almost mandatory to avoid being spammed....Newsreaders that don't have integrated email will be launching the normal email program with normal email address. You definately have a point, but I've honestly never come across this actually happening before. >Checking around I also came across: > >From: Promos(a)Glengarry Wines > >Which appears to be a legit little mailout sent last week from >e-wine(a)Glengarry.co.nz . I didn't see any others in the search. Are you talking about the envelope-sender address or the "From:" header ? It looks like you're talking about the From: header here. I'm (and presumably Chris was) talking about the envelope from address, as exchanged at the beginning of the SMTP transaction... >Our spam filtering also has a "No MX for From address" rules that helps >block those. Still if you feel comfortable blocking customer's email on >that basis I guess it's your choice. It's not part of a spam filter, its just a standard sendmail setting, which defaults to on. (I could turn it off if I wanted to) You made me curious though, so I did a quick survey of the ISP's listed in iMAG to see if they'd accept a message with a bogus domain as an envelope from address: (not a very scientific survey, but..) Actrix: Yes Baycity: No Clear Net: No Ezysurf: No E3: No HyperNet: Yes Iconz: No Igrin: No Ihug: Yes Inspire: No Iprolink: Yes Jafa Net: No Kc Computer: No Maxnet: Yes Net4U: Yes Orcon: Yes paradise.net: No Planet: No Quik: No Quicksilver: No Slingshot: Yes Valuenet: Yes Watchdog: Yes Wave: No Worldnet: Yes Xtra: Yes Zip Internet: Yes Thats 13 Yes's, and 14 No's. A couple of remarks - a few are actually virutal ISP's sharing the same mailserver so that would skew the results a bit, also I only checked the primary MX. I also suspect that it really comes down to the defaults of the mailserver in question rather than a thought-out policy, as most (but not all) the servers that rejected the bogus message were sendmail, or looked like sendmail, and that is the default of sendmail. (As an aside, I noticed more than one who were running ancient versions of sendmail that have, umm, known bugs.... ahem :) Regards, Simon Byrnand iGRIN Internet - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

The answer would be yes. > I would like to find out what other NZ ISPs are doing in this area > with the hope of learning what works and what won't. A small clarification, I nearly posted this yesterday but it didnt seem appropriate or required at the time... Im one of the helpdesk team at the ISP Lin also works for. Our helpdesk is familiar with Outlook Express but that doesnt mean we're close minded about it. We regularly support clients who use other mailing software and as long as the software is reasonably generic we manage. We dont force our clients to use OE, but we do suggest it to our clients *because its there*. The differentiation is important, and stereotyping against helpdesk types isnt going to help. We all start somewhere. :-) I run Eudora in Sponsored mode and find it more than adequate - never caught anything through that, and I have never run resident antivirus either. (I manually scan my system from time to time using F-Prot for DOS.) Prior to using Eudora I used Netscape Messenger (4.x) and found this was also pretty good, although the limitation to only one mailbox is what forced me to migrate. Now that Netscape 7 is out I may consider switching back soon.... I think most ISP helpdesks crewed by reasonable people will accept that their clients dont *have* to use Outlook Express, and the only reason they may encourage their clients to use it is that especially for the less-than- technically-savvy sort, OE is easy to setup, and provided with all versions of Windows from 98 upward. If you work for an ISP and you dont have support staff familiar with a broader range of email clients than Outlook and Outlook Express, I would seriously suggest some more training is in order: Eudora, Netscape Messenger and Pegasus come to mind as alternatives, but theres obviously a lot more. </end rant> Mark. - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

I'm not really happy that this sort of posting meets the AUP, which talks about discussion between operators. There are cetainly announcements which may be of value to the list, but these seem to me to be characterised by not being present on a routine basis in other forums. I think that to allow announcements of this kind would have an unacceptable effect on the signal to noise ratio of the list. Unless people particularly want to see these here, I intend in future to treat them as outside the AUP. - Donald Neal NZNOG List Administrator > E-Secure-IT has just received this field report: > > While it does all the normal mass mailing stuff, own smtp engine, > harvests address lists etc this one did something really weird that > I've never seen before- it sent a postscript print job to > every printer > it could find. > > The scary thing was it even picked up printers attached to parallel > ports and which were not shared and sent the print job to them too. > I know it tries to access network shares, but looks like it tries to > access print q's also, be interested to see if anyone else has > seen this? > > FYI can confirm that NAV sigs of 30/9 do detect and clean. > > Arjen > www.e-secure-db.us ------------------------------------------------------------------------------ "This communication, including any attachments, is confidential.
