Hello All, A (simplified)map of the network layout is:

        +--------+  | network A.0.0.0/24
        | router |+-+
        +--------+  |  +----------+  | network B.0.0.0/24
                    |+-| firewall |+-+
                    |  +----------+  |
                    |
        +--------+  |
        | tcpdump|+-+
        +--------+  |
        
        the tcpdump box does not see -any- packets from network B using

        #ssh -f A.0.0.190 '/usr/sbin/tcpdump -l -n -tt | \
          grep -v A.0.0.190' > /home/biglogs/tcpdump.log

        I know there are better ways of doing the filtering of the ssh
        connection back to my loghost , But this works (sort of) .

        If anyone can point me in the right direction I would greatly
        appreciate the kindness .  Tia,  JimL
PS:     Yes I own network B.0.0.0 ;-)
