Hiya,
Just to let you know that I got the load balancing (using
LinuxVirtualServer) working fine the other day. Thanks to Liam, and Kate for
help.
The main problem was that the system didn't like having two IP addresses on
the one NIC. I'm not sure why, because I have used this method before for
testing purposes (because having two IP addresses on the one card is both
inefficient and insecure). Anyway, when I put in the second NIC, everything
was fine. I don't know why it didn't work this time.... any ideas?
System I had it running on a few years ago: Redhat 6.1 -
Kernel 2.2.12 (i think) - NIC = 3Com 3C905
New system: Redhat 7.1 -
Kernel 2.2.19, 2.4.3/5/8 - NIC = 3Com 3C900
Right so I have a brain teaser for you. Does anyone know how to temporarily
disable one of the processors on a dual processor machine? Basically just to
tell the kernel not to use the second processor for the time being? Any
/proc settings? My feeling is that while being tricky, it should be possible
for the kernel to achieve this.
Thanks,
Tim
