We want to use CNR 5.5 ip history feature. After enabling ip-history and giving ip-history-dir, we got the history database. But when we query history data through iphist utility, we got an error which told us error user/passord, or the error message AX_ENOENT. what is the default user/password? I can not find explanation about it in materials like user guide etc. Please help me. Thanks.
