Can't get Identify open data channels to YES

[Reinoud Koornstra <sockstat () hotmail com>]

Hi Everyone,

 

I am trying to get the ftp data to be checked completely.

When running snort it tells me:

 

    FTP CONFIG:
      FTP Server: default
        Ports (PAF): 21 2100 3535 
        Check for Telnet Cmds: YES alert: YES
        Ignore Telnet Cmd Operations: YES alert: YES
        Identify open data channels: NO


How can i get Identify open data channels to YES?

Here the part of my snort.conf that matters:

 

preprocessor ftp_telnet: global inspection_type stateful encrypted_traffic no check_encrypted
preprocessor ftp_telnet_protocol: telnet \
    ayt_attack_thresh 20 \
    normalize ports { 23 } \
    detect_anomalies
preprocessor ftp_telnet_protocol: ftp server default \
    def_max_param_len 100 \
    ports { 21 2100 3535 } \
    telnet_cmds yes \
    ignore_telnet_erase_cmds yes \
    ignore_data_chan no \


What am I doing wrong?

Thanks,

 

Reinoud.
