Got a problem with ipacces-telnet. My goal is to run osmo-nitb, and do some experimenting. After a factory default reset, the following commands are given: (192.168.1.11 is ip-address of the nanoBTS) ./ipaccess-config 192.168.1.11 -u 1808/0/0 ./ipaccess-config 192.168.1.11 -o 192.168.1.1 ./ipaccess-config 192.168.1.11 -r (wait) ./ipaccess-config -n 0x400/0x400 192.168.1.11 Then I start ipaccess-telnet : ipaccess-telnet 192.168.1.11 3210 And I start osmo-ntib: osmo-nitb --config-file openbsc900.cfg ========================================================== The biggest problem, that makes debugging difficult, is that I after having run osmo-nitb, I cannot use ipaccess-telnet anymore. I have put in some additional prints into ip-access-auth.c to monitor the nanoBTS response: Two examples of OK response, before osmo-nitb is run: response: 3C 31 25 01 7C 3B B2 23 D6 7D 5D 84 17 62 9A 2E 9D 3E = "<1% |;?#?}]? b?.?>" (length = 18) response: 3C 76 B9 88 4C 43 D8 E3 1E 9A 2A 81 DD A0 C7 AC A5 3E = "<v??LC?? ?*??O?>" (length = 18) Two examples of response when nanoBTS refuse connection after having run osmo-nitb: response: 7B 58 0D 7C A4 50 75 83 2B FB 38 F2 66 AD B0 B6 AA 7D = {X?|?Pu?+?8?f????}" (length = 18) response: 7B 43 4A E6 5B A7 E2 1D 1C 8D F4 88 FF FB 26 F6 69 7D = "{CJ?[?? ?????&?i}" (length = 18) Only a factory default reset will make ipaccess-telnet working again. ========================================================== Output from osmo-nitb: <0019> input/ipaccess.c:945 enabling ipaccess BSC mode DB: Database initialized.
