Full Discussion: Need to relate Radius log entries to DHCP ones

So you need the MAC address and the IP address from the DHCP server??

Use awk or perl to scan in the DHCP file and remember mac/ip's. Then scan in the radius log, matching MACs to the hash-array used in step 1. Print the line from radius log with the extra info:
Code:
#!/usr/bin/perl

# To use: script dhcp.log radius.log

open(DHCP,shift @ARGV) || die "Cannot open DHCP logfile: $!";
open(RADIUS,shift @ARGV) || die "Cannot open RADIUS logfile: $!";

while (<DHCP>) { 
   next unless /DHCPACK on (\S+) to (\S+)/;
   $mac2ip{ lc($2) } = $1;
}

while (<RADIUS>) { 
   next unless /Auth: Login OK:.* cli (\w+)\)/;
   # remove trailing newline
   chomp;
   # grab mac address.
   $mac=lc($1);
   # convert to dhcp-style
   $mac =~ s/(\w\w)(\w\w)/$1:$2/g;
   # lookup ip from previous step
   $ip = exists $mac2ip{ $mac } ? $mac2ip{ $mac } : "UNKNOWN";
   # print original line with ip info
   print $_," $ip\n";
}

Tweaks might be necessary.
