[Serusers] Problems inspecting SER with ngrep

[Alberto Cruz]

Hi all, I'm trying to inspect the packets that are arriving to my SER 
server with ngrep but when I executed the command I got the following:

[root at matrix root]# ngrep @sip.telereunion.com.mx port 5060
interface: eth0 (65.208.39.208/255.255.255.240)
filter: ip and ( port 5060 )
match: @sip.telereunion.com.mx
##

As you can see I'm only getting hash symbol. Does anybody know how could 
I display the right info?
I'm running RedHat Linux 9.0, ser 0.9.1, ngrep 1.43 and libcap 0.8.3

Regards
