Re: [swinog] background migration of swisscom connection from IPv4 native to v6 + DS-Lite

Which makes the whole "I want this to be compatible so I do not have to change infra or end points" totally moot. Worse, then you have "old IPv4" and "new IPv4" machines who might or might not be able to talk to each other, depending on which IPv4 address the "new IPv4" got (a long one or a short one) - while with IPv6, you have unmodified old IPv4 to ensure compatibility during the transition, and then you turn it off (in 10 years or so). --------------------------------------------------- I guess all ways IETF participants thought of a new address space would not have allowed backwards compatibility with IPv4? Thanks for the explanation. I appreciate it. Hopefully, others here find it interesting, too. scott

This one, too... :) I was not around for those discussions (and not being a computer science person, nor wanting to go on this for too long as has been endlessly done on other lists), but it seems TLV would have allowed 4 to be a subset of the new space. I never heard that discussed much and that's what I meant by my comment. scott

GSM AT command to set 'Validity Period'?
by Benoit Panizzon 16 Oct '17

16 Oct '17

Dear Swinogers We use smsd to send our nagios alarms via a GSM usb stick. I'm looking for some advice after I was not able to find a working solution. The mobile operator we use has a somewhat short queue to accept SMS and when a recipient is not getting the SMS (mobile off during vacation or whatever) this sms blocks the queue until it expires. If the queue is full, no more sms are being accepted. The SMS are being sent with a default validity period of 7 days. So they expire from the queue after this period. Well, the easy solution would be to sent the period to a couple of hours. No need for techs to get old SMS. What I did is: AT+CSMP=17,143,0,0 // Set Validity Period to 12 hours. AT+CSAS // Save settings to SIM If I query the settings: AT+CSMP? I see these values are set. But after contacting the mobile operator to check if the VP is correct, he tells me we still send them with default 7 days. Does anyone have a hint on how to set the VP correctly via AT commands? Kind regards -Benoît Panizzon- -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________
