Hi,

Can anyone help me out in disabling SMP in Redhat Linux Enterprises server 5. As my Cisco VPN Client does not support SMP.

hope this is what you mean. You will need to reboot to apply the changes.

If that works and you want to make it permanent you might consider editing

config files for either lilo or grub (I have no idea about grub2) generally found in /boot/grub/menu.lst for example.

I was just reading about this earlier today... maxcpus=1 may be another way, but not together 'maxcpus=1 nosmp'

Those will work, however the next question from me is:
Why are you running RHEL ?. That's a licensed distro - if you are paying for support, ask them. If you're not paying for support, you probably shouldn't be asking support type questions on a public forum.
