Newbie questions: Kc thru vty and CHAN_REQ

Hi list !! Three newbie questions: 1.- What is the correct way to put Kc in the the sim-test ? the help command says: ki Set Key (Kc) on test card there are two options: - ki comp128 HEX HEX HEX HEX HEX HEX HEX HEX HEX HEX HEX HEX HEX HEX HEX HEX (i think this is to fix the Ki value - 16bytes) - ki xor HEX HEX HEX HEX HEX HEX HEX HEX HEX HEX HEX HEX (this one need 12 bytes, when Kc it's only 8) 2.- In both calls type MOC and MTC i can't see the CHAN_REQ frame from MS in wireshark. I only get the RR IMM_ASS_CMD from BTS and the rest of the traffic: (from wireshark) to_MS 12:34:38.411650 GSMTAP (CCCH) (RR) Immediate Assignment from-MS 12:34:38.411675 LAPDm U, func=UI(DTAP) (RR) Measurement Report from-MS 12:34:38.411695 LAPDm U P, func=SABM(DTAP) (MM) CM Service Request to-MS 12:34:38.431273 GSMTAP (CCCH) (RR) Immediate Assignment (from my mobile app logs) Sun Mar 6 12:34:38 2011 <0001> gsm48_rr.c:363 new state idle -> connection pending Sun Mar 6 12:34:38 2011 <0001> gsm48_rr.c:1313 CHANNEL REQUEST: e0 (Orig TCH/F) (but i don't see this one in wireshark) Sun Mar 6 12:34:38 2011 <0004> gsm48_mm.c:887 new state MM IDLE, normal service -> wait for RR connection (MM connection) 3.- How must I activate the timestamp in the logs ? I'm using: //target->print_timestamp = 0; target->print_timestamp = 1; But i guess that there is an easy way without recompile... Thanx in advance !!
