ULL presentation
by JIm Romaguera 03 May '07

03 May '07

Hi, I saw that the upcoming Swinog agenda has a free slot at 11:15-12:00 (at least I guess it's free - stated "reserved"). It would be interesting for me, and I think the provider community as well, to see Swisscom give a presentation on ULL. Something like "Technical Aspects of Provider's implementing the current Swisscom defined ULL". The timing of Swinog and the current Swisscom deadlines for ULL make the theme very actual. BTW: I don't expect Swisscom to come and defend the commercial aspect - just elaborate upon the technical aspects. If the Swinog Core Team agrees and can find space in the agenda, plus some of our Swisscom colleagues on the list can coordinate internally within Swisscom, maybe someone suitable within Swisscom could be found to give such a presentation? Cheers JIm

FYI: [c-nsp] Cisco recall on 3560 and 3750 switches and PWR-2300RPS

---------- Forwarded message ---------- From: Hank Nussbacher <hank(a)efes.iucc.ac.il> Date: 24.04.2007 01:00 Subject: [c-nsp] Cisco recall on 3560 and 3750 switches and PWR-2300RPS To: cisco-nsp(a)puck.nether.net Cc: cisco-l(a)listserv.ac.il "Although there has not been a reported safety incident, Cisco is aware of a potential safety issue that can be caused by a welded nut breaking free inside the switch and Redundant Power Supply (RPS). Tightening the mounting screws used to secure the power supply or blower module to the switch or the RPS can lead to a welded nut on the interior to the switch or RPS breaking free from the chassis sheet metal. A risk of electric shock may exist if the chassis is not properly grounded and the loose nut comes in contact with the power supply line-in and chassis." There is no workaround. To check whether your switch needs to be replaced and to submit your details for the RMA go to the following page: http://www.cisco.com/en/US/customer/products/ps7077/products_field_notice09… [available to registered users] This alert is not only for 3560 and 3750 switches but also for owners of RPS - PWR-2300RPS.

SMS from Orange Customers
by Matthias Hertzog 19 Apr '07

19 Apr '07

Hi there! We currently operate our own ShortID 20037 with seperate large accounts from Swisscom, Sunrise and Orange. Since Orange is no longer able to deliver large accounts _without_ the payment options (CHF 2500.-/Month), we're looking for a company that is able to "host" our 20037 for incoming SMS traffic from Orange mobile subscribers. We don't need outgoing traffic, only a handfull of incoming SMS. (Mobile -> LargeAccount). If you can operate that or know someone who can, contact me off-list please. Thanks and best wishes, Matthias _________________________________________ mhs @ internet AG Zürcherstrasse 204, CH - 9014 St. Gallen Phone +41 71 274 93 93, Fax +41 71 274 93 94 http://www.mhs.ch _________________________________________

There is a "passive OS fingerprinting" module for iptables (see http://ippersonality.sourceforge.net/). How about treating connections differently depending on the OS they're coming from? if(windows) then block else allow? :) Or is the OS fingerprint lost through NAT? I don't know.

Exchange Servers having problems with SMTP 4xx temporary failures?
by Benoit Panizzon 12 Apr '07

12 Apr '07

Hi all During the last few days spent tracking strange problems with exchange servers from different companies. From my actual point of view exchange server seam to have troubles with tempfail messages. They notice a 4xx error, tryes again a few times and then occasionaly returns the email to the sender with following message: "Sie sind nicht berechtigt, Nachrichten an diesen Empfänger zu senden. Wenden Sie sich an den Systemadministrator." 550 5.7.1 <lucciola@*>... Relaying denied> This Relaying denied definitely is not from the server receiving the email. There I can only find tempfails. I also have seen other messages than relaying denied there which made even less sense. This happened a few times with graylists tempfails and also happens with a customer sending quite a lot of mails from his exchange and running into sendmails reject=452 4.3.2 Too many open connections. limit. Have other seen this behaviour of exchange servers and know how to prevent it? The strage thing is this only seams happens occasionaly. It can be that the customer sends a mail to hundreds of recipients, causes many tempfails about 'too many open connections' but the emails eventualy get through without problem after a while. I guess it could be, that exchange mixes up message status from other emails and just sends the wrong error message back to the sender.

Is that outbound from $customer -> $internet, or is that also for inbound $internet -> $customer? Having a block on port 25/tcp, 137-139/udp and some other magic virusports is acceptable on end-user IP's. BUT as long as the user of that line has the option to easily turn this off. Eg using a webinterface where they can login using their user/pass and then enable it again, that is disable the block. If that is not possible, then when a user moans about not getting "Internet connectivity" they are quite right. Users who are not the typical techy, can always use 587 as you indicated and should, in general, keep the block on. To avoid problems there, make a simple policy: if found spreading a virus/spamming and having disabled the blockage: no Internet for a week. Or a similar measure that can of course be lifted after paying a fine.

: You'd be amazed how many companies operate their own : mail servers, even behind dynamic addresses I'm speaking with guys in my company on an issue and part of the discussion has to do with me saying no one runs a mail server from behind a dynamic IP addresses.

You'd be amazed how many companies operate their own mail servers, even behind dynamic addresses (in which case they usually use some mailbox polling mechanism to feed their server from mail from the outside), but send outgoing mail directly with SMTP. > Of course, one day we need a better protocol than SMTP (*Simple* Mail > Transfer Protocol) which was never meant as a global email solution. > But until then we have to do something to stop people abusing it.

does Econophone block port25
by Michele Capobianco 04 Apr '07

04 Apr '07

I will tell all our costumers to not use econophone/tele2 anymore. That is no behavior! And on the econophone FAQ is nothing about that. But to be honest i did not think about tele2 FAQ at the first time. Greets Michele

Don't really know anything about it... might help if you upgrade the firmware, but i think its a bad move to tell half of the IT world that Econophone is having an open Network without any firewall ;-) cheers marco -----Original Message----- From: swinog-bounces(a)lists.swinog.ch [mailto:swinog-bounces@lists.swinog.ch] On Behalf Of Michele Capobianco Sent: Mittwoch, 4.

Mailout Server
by Michele Capobianco 03 Apr '07

03 Apr '07

Hey all Does anybody know a Mailserver Software dedicated for Mailout? The idea is : If you send Mails to x Adresses (every Mail has his own <to> adress) it works like a normal Mailout server. If you send a Mail to 1 <to> adress and to 10000 <bcc> the Server noticed that and send the 10000 in packages of (for example) 50perHour. We would like the Software is for Windows. But i just want to know if there is such a Software Linux or Windows. Thanks for your Help. Michele
