I apologize for the LVS "newbie" questions but I was hopinh someone could
take a look at my settings to help me determine if all is ok. I am not
certain things are running properly. My Network consists of the following.
LINUX_LVS (RH 6.2 with 2 NICs to be LVS eth0:DHCP to DSL Connection
and currently 216.232.98.221. eth0: 192.168.1.1 connected to Hub)
LINUX_RS1 (RH 6.2 with one NIC to be Real Server. eth0: 192.168.1.2
Server (NT Server 4, IIS and 1 NIC eth0: 192.168.1.4
Johnny (NT WS 4 with 1 NIC eth0: 192.168.1.3) Main Workstation
The LINUX_LVS has two nics, one going to a hub which connects the others,
and the other to a DSL modem.
I am trying to setup the LINUX_LVS machine as a Firewall/Proxy so all other
machines have Internet Access and as a LVS. I can get out to the Internet
and the LINUX_LVS is running Pulse and I can hear it sending the "rsh
192.168.1.2 uptime" command to the LINUX_RS1 box every ten seconds, but how
do I know if things are working? When I access the internet the only machine
I hear chuggin away is my Main Worksation, and the LINUX_LVS box. How do I
know that the LINUX_RS1 box running RH 6.2 and Apache, and the Server box
running NTS4 amd IIS, are all working as HTTP? I hope this is not too much
trouble but here are my system details. I was also hoping to have the
LINUX_LVS machine use itself rather than just to route/load balance
requests. Any monitoring tools would also be helpful if anyone knows of any.
I also created a .rhosts file on LINUX_RS1 so that the "rsh 192.168.1.2
uptime" will work.
