Hi I wanted to ask if anyone came across this problem. I got freeradius 3.0.2 and enabled the perl module. and after fiddling with it I found some issues the change that I made was to example.pl by doing this --- # Function to handle authenticate sub authenticate { my $memcache_key = $RAD_REQUEST{'User-Name'}; open( my $fh, '>', '/tmp/x2' ); print $fh $memcache_key; close( $fh ); return RLM_MODULE_OK; } --- and I was expecting to get the username in /tmp/x2 file but instead I got this --- [root@radius perl]# cat /tmp/x2 this_is_my_user_but_what_is_this pc|wo ▒" ▒▒;▒▒;▒▒;▒▒;▒{▒ ;b ▒4b|wn''▒▒; 0▒}▒ٞd▒▒;0▒} ▒▒;▒▒;P▒}▒.▒dUNIVERSAL::Ğd(▒▒▒@c@ pc|,,▒.▒d ▒▒0▒}▒ٞd▒1[|wn(▒▒▒▒▒▒P ▒.▒d0▒}p z▒▒2b`{▒{▒Qba▒▒▒▒b▒2b0▒}P▒▒▒▒b ▒"@▒▒ ▒▒▒P▒} 0▒}▒2b▒2b▒{▒▒2b;b0 Z<b0▒}0▒} --- the user that I tested with is: "this_is_my_user_but_what_is_this". I tested it with different lengths of usernames and it seems to be a leak somewhere as the returns jumps around so unless I am doing something completely wrong, this might be an issue with the way the variables are passed on. The odd thing is that if I use the internal debugger the strings seem to be correct. Kind Regards, Sorin
