    There are several methods of updating the software depending on what OS your running and if you need any custom options.

    If your running CentOS,FC or whitebox linux then its simple

    ssh into server

    yum update openssl

    thats all there is to it

    if your on RHEL then up2date openssl

    freeBSD your on your own with that one

    you need to reread chirpys suggestion

    it does not say not to update it

    it says the version number will not be current because they backport fixes into the old version

    as I said above use up2date and you will get the backported updated version

    yap, you are right..

    dave, what would be the exact command to upgrade sshd on RedHat Enterprise 3 and 4?

    I readed this guide from eth0's website: http://www.eth0.us/sshd .. is your upgrade method the same as he explain in that article ?

    The question is, why do you need to upgrade openSSH? Unless you experience vulnerabilities, or have v3.4 or earlier.

    On RHEL3,4 all you have to do is run up2date -u -v to update all packages that need to be updated with the exception of the packages listed in the exclude list and a cpanel upcp will keep those updated.

    one exception to the above rules is the kernel

    to update the kernel you do this

    up2date --nox -f kernel or kernel-smp depending on if you have mutli processors or not

    This will not update any packages compiled from source that RHEL or cpanel did not install
