[ILUG] Interactions between

[spirals]

Hi, I have run into a problem with guarddog interacting with (blocking)  
ssh.
As per my last email, I am running Debian on two test machines located 
side by side and connected via a hub.  I installed ssh and 
openssh-server as was suggested in the reply (have saturated myself 
reading the related RFCs). However I cannot establish a ssh connection 
with guarddog active despite setting ssh remote login as permitted with 
the guarddog GUI.  With guarddog disabled at each end, I can connect 
with ssh and sftp works too.
The machines: ASUS  A7V8X-X, 1GB memory, 2.4 Ghz Duron, 6GB disk 
contains 20GB swap.
Hub 100Mb 16 port Ovislink  FH16P

uname gives: "pene 2.6.18-6-k7 #1 SMP Sun Feb 10 22:16:15 UTC 2008 i686 
GNU/Linux"

ssh -V gives: OpenSSH_4.3p2 Debian-9, OpenSSL 0.9.8c 05 Sep 2006

Any suggestions please?  Better/different firewall ?
