Dear Harald, thank you for explanation, I really appreciate it. So, osmo-hlr now need authentication for connect to the network? so we cannot attach IMSI without the ki?
if Im not wrong I need to set disable it on the configuration? location updating reject cause 13 encryption a5 1 authentication optional on this authentication line need to change? I try do change to authentication disable, but not work. I believe I have wrong understanding here. Im using for 2g network. as far I know only for 3g network you need ki right? Hope some feedback. Thank you. regards, DUO On Fri, Feb 2, 2018 at 7:13 AM, Harald Welte <lafo...@gnumonks.org> wrote: > Hi! > > On Thu, Feb 01, 2018 at 07:14:41PM +0000, Sandi Suhendro wrote: > > 20180201190135844 DAUC <0003> hlr.c:79 510106127044410: IMSI known, but > has > > no auth data; Returning slightly inaccurate cause 'IMSI Unknown' via GSUP > > the error is quite clear: You have only an IMSI in your HLR, but no > authentication > tokens (key material) for cryptographic authentication. > > If at the same time you have configured your network to perform > authentication (i.e. > not explicitly disabled it), then this will of course result in an error. > > Either you enter key data in the HLR for your SIM cards, or you disable > authentication. > > > Does the new osmo-bsc on master cannot use? or maybe I need to > investigate > > more? > > The BSC has nothing to do with it.
