Hi, I believe the redback_telnet in checkrad.pl has a small bug. Original code starting at line 1338 #Ask the question @lines = $t->cmd(String => "show subscribers active $user\@$context"); if ($lines[0] =~ /subscriber $user\@$context/ ) { Should be #Ask the question @lines = $t->cmd(String => "show subscribers active $user\@$context"); if ($lines[0] =~ /subscriber $user\@$context/ ) { ie the $user\@$context needs to be on the same line, at least with our redback.
