It's strange that rlm_sim_files was unable to find auth vectors.
Ensure that simtriplets.dat has UNIX line endings (LF, not CRLF).

i'm sorry i dont understand about LF UNIX line ending, could you show me
what should i do to simtriplets.dat format?
is there any mistake?

2.
Your users format is ok: 16-octet RAND, 4-octet SRES, 8-octet Kc.

Auth vectors in users file differ from those in simtriplets.dat. You cannot
use arbitrary auth vectors. EAP-SIM is mutual authentication protocol. UE
checks that AAA knows correct auth vectors when Request/SIM/Challenge
received before sending Response/SIM/Challenge.

i got that format in /src/tests/eapsim-03/users-example.txt
what should i fill in Rand1 attribute?

thanx for your advice
best regard
