Hello,

Sorry for the html I am using a web interface to send these 
posts.
I hope this is now in ascii.

One thing I have noticed is when setting TCP logging on the 
wingate router (win98) machine and then connecting to the 
director on port 80 I do not see any loging for the 
connection from the director.

It looks like the director is not forwarding the requests 
onwards!

Another point I should make the Director is a matrox server 
with a pre installed linux kernel that fasthosts have built.

The info from uname =
Linux server1 2.2.19-6.2.7 #1 Thu Jun 14 06:57:47 EDT 2001 
i686 unknown

I checked the modules and found these already installed on 
the server.

ls -l /lib/modules/2.2.19-6.2.7/ipv4/

OS = Matrix Server Type 1 Red Hat Linux release 6.2

ipvsadm was not available so I installed 
ipvs-1.0.8-2.2.19.tar.gz (pls note I did not patch the 
kernel)

I run the commands :-
ipvsadm -A -t 212.20.20.2:80 -s rr
ipvsadm -a -t 212.20.20.2:80 -r 192.55.55.81 -i -w 1

and it appeared to work as the ipvsadm command returned 
this :-
IP Virtual Server version 1.0.6 
(size=4096)                    
Prot LocalAddress:Port Scheduler 
Flags                         
 -> RemoteAddress:Port             Forward Weight 
ActiveConn InActConn
TCP  212.20.20.2:80 rr
 -> 192.55.55.81:80     Tunnel  1      0          0   

But as mentioned above when I telnet to 212.20.20.2 on port 
80

I see 1 InActConn and I do not see any TCP activity at 
192.55.55.81 (the Winroute router)?

Are the ip_vs_... modules specific to LVS?

Can these modules be available even if the kernel has not 
been patched with ipvs-1.0.8-2.2.19.tar.gz?

Would the ipvsadm commands appear to work if the kernel has 
not been patched?

The problem I have is that I do not want to build a new 
kernel (unless I am absolutely sure that it is the kernel 
at fault) as I have no physical access to this machine I 
can only telnet remotely. If I build a kernel that does not 
work I have no way of restore the original.

Thank you for your on going help.

SG
