Hi, Currently my "Simultaneous-Use" attribute is not working and I have few questions regarding this. Following are my setup: ================ OS: CentOS 5.3 freeradius2-2.1.6 MySQL 5.0.45 PERL 5.8.8 =============== I am consulting the FAQ checklist. Some are not applicable to me since I am doing everything from SQL. 1) FAQ says "uncheck the Simutaneus check query in sql.conf" but I couldn't find that in in my sql.conf. Where is this in FR2? 2) in "/etc/raddb/sites-enable/default" I noticed that "radutmp" is uncommented by default in "session" and "accounting" section. I tried disabling this but no effect on simultaneous use. Do I need to turn on "radutmp" for something else (like for "radwho"? (What I mean is does any other part the freeradius use this feature for session and accounting purpose? Is it necessary to turn on this feature if I am using SQL for my session and accounting?) 3) I am trying to use "radwho" and it is giving me the error ========== "radwho: Error reading /var/log/radius/sradutmp: No such file or directory". ========== It is looking for "sradutmp" instead of "radutmp" which is not there. I guess probably it has its historical reasons. May be I can solve this my renaming the "radutmp" to "sradutmp" but I am not sure if I want to do that. 4) What are the other things I need to look for to solve this problem? Some suggestions greatly appreciated Thanks -- ============================== Registered Linux User #460714 Currently Using Fedora 10, CentOS 5.3 ==============================
